International Patent Application No. PCT/CN2016/096097 entitled
"ELECTRIC POWER MANAGEMENT SYSTEM AND METHOD" filed on Aug. 19,
2016, the contents of which are hereby incorporated by
reference.
[0034] FIG. 1 is a schematic diagram illustrating an application
scenario of an environmental parameter measurement system 110
according to some embodiments of the present disclosure. In some
embodiments, the environmental parameter measurement system 110 may
be installed inside a house building 100. The house building 100
may be a residential building, a public building, and/or an
industrial building, or the like. In some embodiments, the parts or
components of the environmental parameter measurement system 110
may be mounted on different locations, rooms, buildings, or other
places. A sensing device, a data obtaining device, a data
processing device, a data storage and other devices in the
environmental parameter measurement system 110 may communicate with
each other via a wireless connection or a wired connection.
[0035] In some embodiments, the environmental parameter measurement
system 110 may measure one or more environmental parameters and
compensate the measured value of the environmental parameters. In
some embodiments, the environmental parameter may be temperature,
relative humidity, absolute humidity, a gas pressure, a partial
pressure of a certain gas (e.g., nitrogen, oxygen, or carbon
dioxide, etc.), particulate matter in the air, etc. As an example,
the measured value of the environmental parameter may be a current
measured value (also referred to as a "target measured value") of
the environmental parameter.
[0036] It may also exit a second sensing device 120 and a heat
generating device 130 inside the building 100. The heat generating
device 130 may be a device generating heat and dissipating the heat
outward during operation. In some embodiments, the heat may be
generated based on a thermal effect of a current caused by the
operation of the heat generating device 130. In some embodiments,
the heat generating device 130 may be a powered device, such as a
household electric appliance. As an example, the household electric
appliance may be an air conditioner, a television, a temperature
and humidity measuring device, a control panel, etc. In some
embodiments, the environmental parameter measuring system 110 may
be integrated with the air conditioner, the television, the
temperature and humidity measuring device, or the control panel. In
some embodiments, when the environmental parameter measurement
system 110 is integrated with the control panel, the components of
the environmental parameter measurement system 110 for sensing,
collecting data, and displaying data may be integrated into the
control panel. For example, the temperature of the environment
surrounding the control panel may be measured by a built-in
temperature sensor in the control panel. The control panel may
upload the measured temperature data to a network server for
processing. The control panel may also download the processed data
from the network server and display the downloaded data via an LCD
screen or an LED screen.
[0037] The second sensing device 120 may collect reference data of
one or more environmental parameters, such as a temperature
reference data, a humidity reference data, etc. The reference data
may include one or more measured values of the environmental
parameter under different measurement conditions. The measurement
conditions may have an effect on the measured value of the
environmental parameter. The measurement conditions may include the
material about a building wall, the electric power of the heat
generating device 130, the power-on duration of the heat generating
device 130, the measured value of the current ambient temperature,
and the measured value of the current indoor humidity, etc.
[0038] In some embodiments, the second sensing device 120 may be
deployed at a position farther from the heat generating device 130.
The position farther from the heat generating device 130 may be a
position located at a distance (also referred to as a "second
distance") not less than a threshold D1 (also referred to as a
"second threshold") with the heat generating device 130 distance.
Wherein, the value of D1 may range from 0 meters to 3 meters, or 0
meters to 5 meters, or at least 1.5 meters. In some embodiments,
the influence of the heat generating device 130 on the reference
data measured by the second sensing device 120 may be negligible.
In some embodiments, when comparing the standard data measured by
the second sensing device 120 along with the heat generating device
130 with the standard data measured by the second sensing device
120 without the heat generating device 130, and the difference
between them in the range of 1%, 2%, 3%, 5%, 8% or 10%, or the
like, it may be considered that the effect of the heat generating
device 130 on the reference data measured by the second sensing
device 120 may be negligible. In some embodiments, the second
sensing device 120 may be used for correction of the environmental
parameter measurement system 110 before leaving a factory. In some
embodiments, the environmental parameter measurement system 110 may
not include the second measurement device 120.
[0039] As an example, the reference data may include a measured
value of the same current ambient temperature, an electric power of
the same heat generating device, and a position relative to the
system 110 or a portion thereof (e.g., the first sensing device 201
of FIG. 2, etc.), reference data of the environmental parameter
measured by the second sensing device 120 (e.g., temperature
reference data and humidity reference data, etc.) under difference
power-on duration conditions of the heat generating device. In some
embodiments, the deviation of the environmental parameter measured
value may be determined according to the reference data of the
environmental parameter. In some embodiments, a reference
environmental parameter time table may be generated, for example, a
reference temperature time table, a reference humidity time table,
etc., according to the reference data of the environmental
parameter or the deviation of the environmental parameter measured
value. In some embodiments, the reference temperature time table
may represent a relationship between a reference temperature and a
power-on duration. In some embodiments, the reference humidity time
table may represent a relationship between reference humidity and
power-on duration.
[0040] The second sensing device 120 may include an infrared
sensor, a pressure sensor, a temperature sensor, a humidity sensor,
or a gas sensor, or the like, according to the measured
environmental parameter. The second sensor 120 may include a
resistive sensor, an inductive sensor, a capacitive sensor and a
potential sensor according to the working principle for the second
sensor 120.
[0041] FIG. 2 is a schematic diagram illustrating an environmental
parameter measurement system 110 according to some embodiments of
the present disclosure. The environmental parameter measurement
system 110 may include a first sensing device 201 and an
environmental parameter compensating device 202. The environmental

the communication module 224.
[0049] The data processing module 222 may process the data. The

and/or the current measured data of the environmental parameter. In
some embodiments, the data processing module 222 may perform a
preprocessing operation on the data. The preprocessing operation
may include processing dark currents, removing dead pixels,
denoising, performing geometric corrections, etc. In some
embodiments, the data processing module 222 may perform operations,
such as correction, on the data. In some embodiments, the data
processing module 222 may generate the compensated data of the
current measured value of the environmental parameter, and correct
the current measured value of the environmental parameter based on
the compensated data to obtain the corrected measured value of the
environmental parameter. The compensated data may be the deviation
of the current measured value of the environmental parameter.
[0050] In some embodiments, the data processing module 222 may
transmit the processed data to the display module 226. In some

temperature after the compensation may be displayed by the display
module 226 allowed by the user control module 223 via the user. As
another example, the user may control the display module 226 to
display only the temperature after the compensation.
[0053] Display module 226 may display data. In some embodiments,
the display module 226 may display the environmental parameter

measurement system 110. As an example, the display module 226 may
display the system in a normal working state. As another example,
the display module 226 may display the system in an abnormal
working state and transmitting a warning signal. As an example,
when the current measured value (e.g., the current temperature
value) of the environmental parameter of the system reaches the
threshold, the system may be in an abnormal working state. In some
embodiments, the threshold may be set by the system 110 based on
the default settings or the results of the machine learning, or
provided by the user. In some embodiments, the threshold of a
certain environmental parameter may be varied with the change of
other environmental parameters. For example, when the ambient
humidity increases, the temperature range over which the system
operates normally may be reduced. In some embodiments, the warning
signal may be an optical signal, an acoustic signal, or a
combination of a plurality of signals. In some embodiments, the
display module 226 may also display network connection status of a
device. In some embodiments, the display module 226 may also

module 222, the user control module 223, and/or the display module
226. In some embodiments, the storage module 225 may receive data
from the above module or transmit data to the above module. As an

[0057] It should be noted that the above description of the
environmental parameter measurement system 110 is merely provided
for convenience of description and not intended to limit the
present disclosure to the scope of the embodiments. For persons
having ordinary skills in the art, modules may be combined in
various ways, or connected with other modules as sub-systems.

teachings of the present disclosure. However, those variations and
modifications may not depart from the spirit and the scope of the
present disclosure.
[0058] FIG. 3 is an exemplary flowchart illustrating an exemplary
process for compensating an environmental parameter according to
some embodiments of the present disclosure. In step 302, the
environmental parameter compensating device 202 may obtain data.
The process of obtaining data may be implemented by the data
obtaining module 221. In some embodiments, the current measured
value of the environmental parameter may be obtained, for example,
the measured value of the current temperature. In some embodiments,
the reference data of the environmental parameter may be obtained.
In some embodiments, the environmental reference data may be
collected by the second sensing device 120. In some embodiments,
the environmental reference data may be transmitted to the data
obtaining module 221 by an external data source.
[0059] In step 304, the environmental parameter compensating device
202 may process the obtained data to obtain the compensated data.
The process of processing data may be implemented by the data
processing module 222. The processing on the data may include a
preprocessing operation on the data, a compensating operation on
the data, or the like, or any combination thereof. The
preprocessing operation on the data may include denoising,
filtering, dark current processing, geometric correction, or the
like, or any combination thereof. In some embodiments, the
compensated data of the current measured value of the environmental
parameter may be obtained according to the reference data of the
environmental parameter. For example, the current measured value of
the environmental parameter may be compensated according to the
compensated data of the current measured value of the environmental
parameter to obtain the measured value of the environmental
parameter after the compensation.
[0060] In step 306, the environmental parameter compensating device
202 may output the compensated data. In some embodiments, the
compensated data may be displayed by the display module 226. In
some embodiments, the data may be transmitted to any external
device, such as a database, a terminal, etc., connected with the
environmental parameter measurement system 110. The database may be
located on the network and collect the compensated data from one or
more environmental parameter measurement system 110. The terminal
may be a user device, for example, a smartphone, a tablet computer,
a laptop computer, a wearable device, etc.
[0061] It should be noted that the above description of the
environmental parameter compensating process is merely provided for
convenience of description and not intended to limit the present
disclosure to the scope of the embodiments. It should be understood
that for persons having ordinary skills in the art, modules may be
combined in various ways, or connected with other modules as
sub-systems. Various variations and modifications may be made under
the teachings of the present disclosure. However, those variations
and modifications may not depart from the spirit and the scope of
the present disclosure. For example, the compensated data obtained
in step 304 may be returned to step 302 for processing again.
[0062] FIG. 4 is a schematic diagram illustrating the data
processing module 222 according to some embodiments of the present
disclosure. The data processing module 222 may include a data
interface unit 410, a data processing unit 420, a determination
unit 430, and a storage unit 440.
[0063] The data interface unit 410 may receive and/or send data
related to the environmental parameter. The data may be the
measured value of the environmental parameter or data related to
the measurement condition. The environmental parameter may be
temperature, humidity, air pressure, partial pressure, particulate
matter content in the air, etc. The measurement condition may be a
condition affecting the measured value of the environmental
parameter, for example, the measured value of the ambient
temperature, the material of the building wall, the electric power
of the heat generating device 130, the operating voltage of the
heat generating device 130, the power-on duration of the heat
generating device 130, etc. Data interface unit 410 may be
connected with the data obtaining module 221, the storage module
225, the display module 226, the data processing unit 420, the
determination unit 430, and/or the storage unit 440. As an example,
data interface unit 410 may obtain data from the data obtaining
module 221 and/or the storage module 225. As another example, the
data interface unit 410 may obtain the reference data and transmit
the obtained reference data to the data processing unit 420, the
determining unit 430, or the storage unit 440.
[0064] The data processing unit 420 may perform analysis and
processing on the received data. For example, the data processing
unit 420 may receive data from the data interface unit 410 and/or
the storage unit 440 and perform analysis processing. As an
example, the data received by the data interface unit 420 may
include the reference data of the environmental parameter and the
current measured value of the environmental parameter. In some
embodiments, the data processing unit 420 may preprocess the
received data. As an example, the preprocessing may include
filtering, dark current, removing noise, geometric correction, or
the like, or any combination thereof. In some embodiments, the data
processing unit 420 may determine the compensated data of the
current measured value of the environmental parameter. As an
example, the data processing unit 420 may analyze the received
reference data to generate a reference temperature time
relationship and a quasi-reference temperature time relationship.
The quasi-reference temperature time relationship may be one or
more temperature time relationships obtained by screening in a
reference temperature time table. In some embodiments, the data
processing unit 420 may perform a fitting calculation on the
reference temperature time relationship to generate a compensating
temperature time table. The compensating temperature time
relationship may be generated based on the one or more
quasi-reference temperature time relationships, and contain the
temperature time relationship of the compensated data of the
current measured value of the environmental parameter. The
compensating temperature time relationship may be used as a
reference for the compensation of the current measured value of the
environmental parameter. The reference temperature time
relationship or the quasi-reference temperature time relationship
may be in the form of a table, such as a reference temperature time
table, a quasi-reference temperature time table, etc. The reference
temperature time relationship or the quasi-reference temperature
time relationship may be in the form of a graph, such as a
reference temperature time diagram, a quasi-reference temperature
time diagram, etc.
[0065] The determination unit 430 may be connected with the data
interface unit 410, the data processing unit 420, and/or the
storage unit 440. In some embodiments, the determination unit 430
may select an algorithm for the data processing unit 420 to perform
a data processing. As an example, the determining unit 430 may
select an algorithm for a compensating temperature time
relationship generated by the quasi-reference temperature time
relationship. The algorithm may include an interpolation method and
an extrapolation method, or the like, or any combination thereof.
The interpolation methods may include a Newton's method, a linear
interpolation method, a polynomial interpolation method, or the
like, or any combination thereof. The extrapolation method may
include a linear extrapolation method, an exponential extrapolation
method, a growth curve method, a trend extrapolation method, or the
like, or any combination thereof.
[0066] The storage unit 440 may store data or related parameters,
etc. The stored data may be data in various forms, such as a
numerical value, a signal, a command, an algorithms, a program, or
the like, or any combination thereof. In some embodiments, the
storage unit 440 may include a fixed storage system (e.g., a
magnetic disk), a mobile storage system (e.g., a universal serial
bus (USB) interface, an interface of a firewire port, and/or a
drive of a disk drive type, etc.). The storage unit 440 may include
a hard disk, a floppy disk, a random access memory, a dynamic
random access memory, a static random access memory, a bubble
memory, a thin film memory, a magnetic plate line memory, a phase
change memory, a flash memory, a cloud disk, or the like, or any
combination thereof.
[0067] In some embodiments, the storage unit 440 may be connected
with the data interface unit 410, the data processing unit 420,
and/or the determination unit 430, and receive data from one or
more of the above units, or transmit data to one or more of the
above units. As an example, the storage unit 440 may store data
transmitted by the data interface unit 410. As another example, the
determining unit 430 may select one or more algorithms stored in
the storage unit 440 as an algorithm for the data processing
performed by the data unit. The storage unit 440 may store
temporary data, i.e., dump data for future data processing. The
storage unit 440 may store the final data, i.e., store a result of
the final data processing.
[0068] It should be noted that the above description of the data
processing module 222 is merely provided for convenience of
description and not intended to limit the present disclosure to the
scope of the embodiments. For persons having ordinary skills in the
art, modules may be combined in various ways, or connected with
other modules as sub-systems. Various variations and modifications
may be made under the teaching of the present disclosure. However,
those variations and modifications may not depart from the spirit
and scope of this disclosure.
[0069] FIG. 5 is an exemplary flowchart illustrating a process of
compensating the environmental parameter according to some
embodiments of the present disclosure. In some embodiments, the
compensation process of the environmental parameter may be
implemented by the data processing module 222.
[0070] In step 502, the current measured data may be obtained. The
measured data may include the current measured data of the
environmental parameter, such as a current measured value of
temperature, a current measured value of humidity, etc. The current
measured data may include a measurement condition of a current
environmental parameter, for example, the current electric power
value of the heat generating device 130, the current power-on
duration (also referred to as "target power-on duration) of the
heat generating device 130, the measured value of the current
ambient temperature, or the like, or any combination thereof. In
some embodiments, the measurement condition may also be referred to
as "a set of target conditions". In some embodiments, the current
measured data may be obtained by the first sensing device 201.
[0071] In step 504, the quasi-reference data may be selected from
the reference data based on the current measured data. In some
embodiments, the reference data may include reference measured data
of an environmental parameter under different measurement
conditions, for example, powers of different heat generating
devices, power-on durations of different heat generating devices,
or under the conditions of the measured value of different
reference ambient temperatures, the reference measured data of the
environment parameter. The reference measured data of the
environmental parameter may be obtained according to the process
shown in FIG. 8 and its description. In some embodiments, the
measurement condition that is closer to the current measured data
may be determined according to the current measured data, and the
reference data under the condition may be selected as the
quasi-reference data. The "closer" as used herein may indicate the
ratio of one or more measurement conditions (e.g., ambient
temperature, humidity or an electric power value) of the
temperature time relationship to the current corresponding
measurement condition may be within a range, for example, 95% to
105%, 90% to 110%, or 85% to 115%, etc.
[0072] In step 506, the compensated data may be generated based on
the quasi-reference data and the current measured data. In some
embodiments, the compensated data of the current measured data may
be generated according to the quasi-reference data. The compensated
data may be generated according to the current measured data and
the compensated data.
[0073] In step 508, the compensated data may be output. In some
embodiments, the compensated data may be output by the display
module 226. In some embodiments, the compensated data may be output
to the storage module 225 for storage.
[0074] It should be noted that the above description of the
environmental parameter compensating process is merely provided for
convenience of description and not intended to limit the present
disclosure to the scope of the embodiments. It will be understood
that for persons having ordinary skills in the art, modules may be
combined in various ways, or connected with other modules as
sub-systems. Various variations and modifications may be made under
the teachings of the present disclosure. However, those variations
and modifications may not depart from the spirit and the scope of
the present disclosure. For example, other operations or
determinations may be added between the step 502 of obtaining the
measurement data and the step 508 of outputting the compensated
data. For example, the obtained current measured data may be stored
and backed up. Similarly, a storage backup step may be added
between any two steps in the process of the FIG. 5.
[0075] FIG. 6 is a schematic diagram illustrating the data
processing unit 420 according to some embodiments of the present
disclosure. The data processing unit 420 may include a
preprocessing sub-unit 610, a generating sub-unit 620, and a
compensating sub-unit 630.
[0076] The preprocessing sub-unit 610 may perform preprocessing
operations on the received data. In some embodiments, the
preprocessing sub-unit 610 may perform on filtering, processing
dark current, removing noise, and geometric correction, or the
like, or any combination thereof. In some embodiments, the
preprocessing sub-unit 610 may filter the received data to select
the required data. In some embodiments, the preprocessing sub-unit
610 may be connected with the generating sub-unit 620. As an
example, the preprocessing sub-unit 610 may transfer the
pre-processed data to the generating sub-unit 620.
[0077] The generating sub-unit 620 may determine the reference
temperature time relationship. In some embodiments, the generating
sub-unit 620 may determine the relationship between the reference
temperature and the running time of the heat generating device 130
(referred to as "the reference temperature time relationship")
according to the reference data. In some embodiments, the reference
data may be obtained by the second sensing device 120. As an
example, the generating sub-unit 620 may determine the relationship
between the reference temperature and the time under different
measurement conditions, with the reference data under different
measurement conditions. In some embodiments, the measurement
condition may be a combination of the power of the heat generating
device 130 and the measured value of the reference ambient
temperature. As an example, the measured value of the reference
ambient temperature may have four temperature values including
T.sub.A, T.sub.B, T.sub.C, and T.sub.D, and the power of the device
may have three electric power values including P.sub.1, P.sub.2,
and P.sub.3. The different measurement conditions may be twelve
kinds of combinations of the aforementioned four temperature values
and the aforementioned three electric power values. The reference
temperature data of the heat generating device 130 under different
power-on duration conditions may be respectively measured based on
the 12 combinations, and the 12 reference temperature time
relationship tables may be generated. As an example, the selection
of T.sub.A, T.sub.B, T.sub.C, and T.sub.D may be arbitrary, or
determined based on the possible upper temperature limits and the
possible lower temperature limits of the actual use environment of
heat generating device 130. For example, the T.sub.A and the
T.sub.D may be selected as the upper temperature limit and the
lower temperature limit, respectively. The T.sub.B and the T.sub.C
may be determined as follows: in a state of P.sub.1, under the
condition of the T.sub.D, a required time from a stable temperature
deviation in the non-operating state of the heat generating device
130 to the stable temperature deviation in the running state of the
heat generating device 130 for the first time, may be determined as
t.sub.a; in the state of the P.sub.1, under the condition of the
T.sub.A, the required time from a stable temperature deviation in
the non-operating state of the heat generating device 130 to the
stable temperature deviation in the running state of the heat
generating device 130 for the first time, may be determined as
t.sub.b; then T.sub.B and T.sub.C may select any node between
t.sub.a and t.sub.b, for example, the temperatures of
(t.sub.b-t.sub.a)/3 and 2(t.sub.b-t.sub.a)/3. Similarly, P.sub.2
may be determined as follows: P.sub.1 and P.sub.3 may be selected
as the upper limits of the power of the heat generating device and
lower limits of the power of the heat generating device. In the
state of the P.sub.1, under the condition of the T.sub.A, the
required time from a stable temperature deviation in the
non-operating state of the heat generating device 130 to the stable
temperature deviation in the running state of the heat generating
device 130 for the first time, may be determined as t.sub.c; in the
state of P.sub.1, under the condition of the T.sub.A, the required
time from a stable temperature deviation in the non-operating state
of the heat generating device 130 to the stable temperature
deviation in the running state of the heat generating device 130
for the first time, may be determined as t.sub.d; then any node
between to and t.sub.b, for example, the temperature of
(t.sub.c-t.sub.d)/2, may be selected. In some embodiments, the
temperature deviation may be a deviation of the measured value of
the current ambient temperature relative to the measured value of
the ambient temperature reference ambient temperature. The stable
temperature deviation may refer to a temperature deviation reached
after the heat generating device 130 remains in the running state
or the non-operating state for a long time. The longer time herein
may be 1 hour, 2 hours, 5 hours or other time.
[0078] The compensating sub-unit 630 may generate the compensated
data of the measured value of the current temperature. In some
embodiments, the measured value of the current temperature may be
obtained by the first sensing device 201. In some embodiments, the
compensating sub-unit 630 may select a quasi-reference temperature
time relationship of one or more measured value of the current
temperature and generate a compensating temperature time
relationship. In some embodiments, N reference temperature time
relationships closer to the current measurement condition may be
selected as the quasi-reference temperature time table, wherein N
may refer to any positive integer. Herein, the "closer" may refer
to a ratio of one or more measurement conditions in the temperature
time table (e.g., the measured value of the ambient temperature, a
measured value of the ambient humidity, or the electric power
value) to the values of current corresponding measurement
conditions may not exceed a range, for example, 95% to 105%, 90% to
110%, or 85% to 115%. In some embodiments, the compensating
sub-unit 630 may generate the compensating temperature time table
according to the quasi-reference temperature time table. As an
example, the compensating sub-unit 630 may perform a fitting
calculation against the quasi-reference temperature time table to
generate a compensating temperature table. In some embodiments, the
compensating sub-unit 630 may also compensate for the current
measured value of the temperature according to the compensating
temperature time table. The fitting calculation method herein may
be a combination of one or more of the aforementioned interpolation
methods or the aforementioned extrapolation methods.
[0079] It should be noted that the above description of the data
processing unit 420 is merely provided for convenience of
description and not intended to limit the present disclosure to the
scope of the embodiments. For persons having ordinary skills in the
art, modules may be combined in various ways, or connected with
other modules as sub-systems, and various modifications and
transformations in form and detail may be conducted under the
teaching of the present disclosure. However, those modifications
and transformations may not depart from the spirit and scope of the
present disclosure. For example, the preprocessing sub-unit 610 and
the generating sub-unit 620 may be combined without the
preprocessing sub-unit 610 being reserved. For another example, the
generating sub-unit 620 and the compensating sub-unit 630 may be
combined, and the compensating sub-unit 630 may implement the
aforementioned function of the generating sub-unit 620. In some
embodiments, the environmental parameter measurement system 110 may
not have the generating sub-unit 620. The reference temperature
time relationship used by the environmental parameter measurement
system 110 for compensating the measured value of the current
environmental parameter may be obtained from the storage device
internal to the system 110 (the data obtaining module 221, the user
control module 223, the storage module 225, etc.) or the external
storage device (e.g., a database on a network, the smartphone, the
tablet computer, the laptop computer, a wearable device, or other
device, etc.). In some embodiments, the obtained reference
temperature time relationship may be measured and obtained by a
system having a similar arrangement of the heat generating device
130 and the first measuring device 201 in the environmental
parameter measuring system 110. See FIG. 8 and its description.
[0080] FIG. 7 is a schematic diagram illustrating a compensating
sub-unit 630 according to some embodiments of the present
disclosure. The compensating sub-unit 630 may include a lookup
sub-unit 710 and a computing sub-unit 720. The lookup sub-unit 710
may look up and select the quasi-reference temperature time
relationship in the reference temperature time relationship. In
some embodiments, the lookup sub-unit 710 may select one or more
reference temperature time relationships close to the current
measurement conditions (e.g., the measured value of the current
ambient temperature and the electric power value of the heat
generating device 130, etc.) as the quasi-reference temperature
time table. Herein, the "close" may refer to the ratio of one or
more measurement conditions (e.g., the measured value of ambient
temperature, the measured value of ambient humidity, or the power
value of the heat generating device 130) of the reference
temperature time relationship to the value of the current
corresponding measurement condition may not exceed a range, for
example, 95% to 105%, 90% to 110%, or 85% to 115%.
[0081] The computing sub-unit 720 may perform a calculation
according to the found quasi-reference temperature time
relationship, and generate the compensated temperature time
relationship. In some embodiments, the computing sub-unit 720 may
perform a fitting calculation (e.g., a combination of one or more
of interpolation, extrapolation, etc.) on the found quasi-reference
temperature time relationship to generate the compensating
temperature time relationship. In some embodiments, the computing
sub-unit 720 may calculate according to the compensating
temperature time relationship, generate the compensated value of
the current measured value of the temperature, and perform
compensation on the current measured value of the temperature. As
an example, the computing sub-unit 720 may perform linear
interpolation or extrapolation based on the compensating
temperature time relationship to generate a compensated value. The
computing sub-unit 720 may also calculate the compensated value
according to other algorithms, for example, other interpolation
methods or extrapolation methods. More details on the interpolation
methods and the extrapolation methods, please refer to the above,
and will not be repeated herein.
[0082] It should be noted that the above description of the
compensating sub-unit 630 is merely provided for convenience of
description and not intended to limit the present disclosure to the
scope of the embodiments. For persons having ordinary skills in the
art, upon understanding the principle of the system, modules may be
combined in various ways, or connected with other modules as
sub-systems. Various variations and modifications may be made under
the teachings of the present disclosure. However, those variations
and modifications may not depart from the spirit and the scope of
the present disclosure. For example, in some embodiments, for
example, when the compensating temperature time table contains the
same or substantially the same temperature data as the current
measured value of the temperature, the computing sub-unit 720 may
also directly obtain the compensated value of the current measured
value of the temperature by the compensating temperature time
relationship without the linearity. Interpolation or the
extrapolation process. The "substantially the same" may refer to
the error between the environmental parameter and the measured
value of the environmental parameter after the compensation is
within the range of system 110 or the range allowed by the
user.
[0083] FIG. 8 is an exemplary flowchart for generating a reference
temperature time relationship according to some embodiments of the
present disclosure. In step 802, a first set of conditions for the
heat generating device 130 may be obtained. The first set of
conditions may be a combination of one or more measurement
conditions. The measurement conditions may include the electric
power of the heat generating device 130, the measured value of the
ambient temperature, and other parameters that may affect the
measurement of the environmental parameter, for example, a
wallpaper material of the environment in which the system 110 is
located, or the like, or any combination thereof. As an example,
the first set of conditions may be a combination of the electric
power of the heat generating device 130 and the measured value of
the ambient temperature. For example, the first set of conditions
may be that electric power of the heat generating device is 90
watts and the measured value of the ambient temperature is
30.degree. C.
[0084] In step 804, a first reference temperature may be obtained
in a first power-on duration of the heat generating device 130
under the first set of conditions. In some embodiments, the first
reference temperature may be measured by the second sensing device
120. The first power-on duration may be any time period t.sub.1 of
the device powered on. For example, t.sub.1 may be selected as 5
seconds, 10 minutes, 1 hour, etc. As an example, under the first
set of conditions, such as the electric power of the heat
generating device as 90 watts and the measured value of the ambient
temperature as 30.degree. C., in the first power-on duration of the
heat generating device, for example, t.sub.1 as 1 hour, the first
reference temperature S1 at this time may be obtained by the second
sensing device 120. In some embodiments, the measured value of the
first ambient temperature may be obtained by the first sensing
device 201 at the same time when the first reference temperature is
obtained, that is, in the first power-on duration. The measured
value of the first ambient temperature may be a measured value of
the ambient temperature obtained by the first sensing device 201
while the first reference temperature obtained. The first
measurement deviation of the ambient temperature may be obtained
according to the measured value of the first ambient temperature
and the first reference temperature as S1.
[0085] In step 806, a second reference temperature may be obtained
in the second power-on duration of the heat generating device 130
under the first set of conditions. In some embodiments, the second
reference temperature may be measured by the second sensing device
120. The second power-on duration may be any time period t.sub.2
(t.sub.2>t.sub.1) when the device is powered on. For example,
t.sub.2 may be selected as 6 seconds, 16 minutes, 2 hours, etc. As
an example, under the conditions of the first set, such as the
electric power of the heat generating device as 90 watts and the
measured value of the ambient temperature as 30.degree. C., in the
second power-on duration of the heat generating device, for
example, when t.sub.2 is 2 hours, the second reference temperature
S2 at this time may be obtained by the second sensing device 120.
In some embodiments, the measured value of the second ambient
temperature may be obtained by the first sensing device 201 while
the second reference temperature is obtained, that is, in the
second power-on duration. The measured value of the second ambient
temperature may be a measured value of the ambient temperature
obtained by the first sensing device 201 while the second reference
temperature is obtained. A second measurement deviation of the
ambient temperature may be obtained according to the measured value
of the second ambient temperature and the second reference
temperature data S2.
[0086] In step 808, the reference temperature time relationship
under the first set of conditions may be generated based on the
first set of conditions, the first reference temperature data, and
the second reference temperature data. As an example, the first
reference temperature (or the first measurement deviation), the
second reference temperature (or the second measurement deviation),
the first power-on duration and the second power-on duration, may
generate a temperature time relationship representing the
temperature time relationship under the first set of conditions. As
an example, under the first set of conditions, for example, the
electric power of the heat generating device as 90 watts, and the
measured value of the ambient temperature as 30.degree. C., the
reference temperature time relationship may be generated according
to the first reference S1, the second reference S2, the first
power-on duration 1 hour, and the second power-on duration 2
hours.
[0087] The reference temperature time relationship for the system
110 may be generated prior to installation of the system 110. For
example, a manufacturer of the system 110 or a portion thereof may
generate one or more reference temperature time relationships for
the arrangement of the heat generating device 130 and the first
measurement device 201. In some embodiments, the one or more
reference temperature time relationship may be generated by the
second environmental parameter measurement system. The second
environmental parameter measurement system has the heat generating
device and the measuring device. In some embodiments, the effect of
the heat generating device of the second environmental parameter
measurement system on its measuring device may be similar to the
effect of the heat generating device 130 on the first measuring
device 201. As an example, the arrangement of the heat generating
device and the measuring device of the second environmental
parameter measurement system, for example, a distance or the like,
may be the same as or similar to the arrangement of the heat
generating device 130 of the environmental parameter measurement
system 110 and the first measuring device 201. As another example,
the user may debug and generate a reference temperature time
relationship suitable for the system 110. As an example, the user
may collect data during the commissioning of the first measurement
device (e.g., one week, one month, etc.), in conjunction with data
collected by the second sensing device during this time, to
generate the aforementioned reference temperature time
relationship. For another example, the system 110 is officially
used for a period of time, for example, one month, one quarter, one
year, etc., the user may re-commission the system 110 and update
the existing reference temperature time relationship table. In some
embodiments, the existing reference temperature time relationship
table may be generated during the debugging process before the
official use, or loaded into the system 110 by the manufacturer
before leaving the factory.
[0088] It should be noted that the above description of the process
of generating the temperature time relationship is merely provided
for convenience of description and not intended to limit the
present disclosure to the scope of the embodiments. For persons
having ordinary skills in the art, upon understanding the principle
of the system, modules may be combined in various ways, or
connected with other modules as sub-systems. Various variations and
modifications may be made under the teachings of the present
disclosure. However, those variations and modifications may not
depart from the spirit and the scope of the present disclosure. For
example, the flowchart is only used as an embodiment of a
temperature environmental parameter compensation, and the
temperature may be replaced with other environmental parameters,
such as humidity, air pressure, partial pressure, airborne
particulate matter contents, etc., to achieve a corresponding
environmental parameter compensating effect. For another example,
under the second group condition, the third group condition . . . ,
the Nth group condition, the step 802 to the step 808 may be
respectively implemented to obtain the temperature time table under
different conditions.
[0089] FIG. 9 is an exemplary flowchart for compensating the
measured value of the current environmental parameter according to
some embodiments of the present disclosure. In step 902, the
relationship among the measured derivation of the environmental
parameter of system 110, the electric power value of the heat
generating device of the system 110 and the power-on duration of
the heat generating device of the system 110 may be obtained. The
measured deviation of the environmental parameter may be the
deviation of the measured value of the environmental parameter and
the corresponding reference data.
[0090] In step 904, the current electric power value of the heat
generating device, the power-on duration of the heat generating
device, and the measured value of the current environmental
parameter may be obtained. In some embodiments, the measured value
of the current environmental parameter may be measured and obtained
by the first sensing device 201. The first sensing device 201 may
be deployed near the heat generating device 130. In some
embodiments, when the measured value of the environmental parameter
is obtained, the electric power and the power-on duration of the
heat generating device 130 may be the current electric power value
and the current power-on duration, respectively.
[0091] In step 906, a measured deviation of the current
environmental parameter may be determined according to the current
electric power value, the current power-on duration, the current
measured value of the environmental parameter and the relationship.
In some embodiments, the existing reference data may be selected
according to the current electric power value of the heat
generating device and the measured value of the current
environmental parameter. In some embodiments, the reference data
measured under a set or sets of measurement conditions that are
closer to the current electric power value and the measured value
of the current environmental parameter may be selected. The
"closer" may refer to the ratio of one or more measurement
conditions (for example, the measured value of the ambient
temperature, the measured value of the ambient humidity, or the
electric power value of the heat generating device) of the
reference temperature time relationship to the value of the current
corresponding measurement condition may not exceed a range, for
example, 95% to 105%, 90% to 110%, or 85% to 115%, etc. The
measurement condition may be a combination of the electric power
value of the reference heat generating device and the measured
value of a reference ambient temperature. In some embodiments, the
reference temperature parameter time relationship of the selected
different electric power of the reference heat generating device
and the reference environmental parameter time relationship under
the reference ambient temperature conditions may be the
quasi-reference temperature time relationship. In some embodiments,
a compensating temperature time relationship may be determined
according to the selected quasi-reference environmental parameter
time relationship. In some embodiments, according to the
compensating environmental parameter time relationship, the
measured value of the current environmental parameter and the
power-on duration of the heat generating device 130, the
measurement deviation of the current environmental parameter, that
is, the current deviation (also referred to as "target deviation"),
may be determined. As an example, the linear interpolation or the
extrapolation may be performed based on the compensating
temperature time relationship to generate the current deviation.
The compensated value may also be calculated according to other
interpolation methods, such as a Newton method, a linear
interpolation method, a polynomial interpolation method, or
extrapolation methods, for example, a linear extrapolation, an
exponential extrapolation, a growth curve method and a trend
extrapolation, etc.
[0092] In step 908, a corrected measured value of the environmental
parameter may be determined based on the current measured value of
the environmental parameter and the current measured deviation. As
an example, the current measured value of the environmental
parameter may be added to or subtracted from the current measured
deviation to obtain the corrected (or "after the compensation")
measured value of the environmental parameter.
[0093] It should be noted that the above description of the
compensation process of the measured value of the current
environmental parameter is merely provided for convenience of
description and not intended to limit the present disclosure to the
scope of the embodiment. For persons having ordinary skills in the
art, modules may be combined in various ways, or connected with
other modules as sub-systems. Various variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications may not depart from the spirit
and the scope of the present disclosure. For example, other
selection or processing conditions may be added between the step
902 and the step 908. For example, the relationship among the
obtained measured deviation of environment parameter of the device,
the obtained electric power value of the device, and the obtained
power-on duration of the device may be stored and backed up.
Similarly, the storage backup step may be added between any two
steps in the flowchart. For example, in some cases, if the
conditions of the power-on duration, the current measured value of
the environmental parameter, or the electric power value of the
heat generating device 130 and/or the power-on duration of the heat
generating device 130 correspond to the existing compensating
temperature time relationship, the compensated value may be
generated by directly querying the data in the compensating
temperature time relationship.
[0094] FIG. 10 shows a schematic diagram of the reference
temperature time relationship (the power of the heat generating
device 130 remains unchanged) according to some embodiments of the
present disclosure. The reference temperature time relationship may
be expressed in the form of a table or function curve. As shown in
FIG. 10, the temperature time relationship shows the relationship
between the deviation for the measured value of the current ambient
temperature of the first sensing device 201 relative to the
measured value of the reference ambient temperature (referred to as
"temperature deviation") and the power-on duration of the heat
generating device 130. Wherein T.sub.0 may be the stable
temperature deviation reached by the heat generating device 130 in
the non-operating state. T.sub.1 may be the stable temperature
deviation reached by the heat generating device 130 in the running
time for a long time. The stable temperature deviation may refer to
the temperature deviation reached after the heat generating device
130 remains in the running state or the non-operating state for a
long time. The longer time herein may be 1 hour, 2 hours, 5 hours
or other time periods. The time to reach the stable temperature
deviation may be related to a combination of one or more factors
such as the type of heat generating device 130, the electric power
of the heat generating device 130, the ambient temperature, and the
ambient humidity. t.sub.r0, t.sub.r1, t.sub.r2, t.sub.r(x-1) and
t.sub.rx may respectively refer to the power-on duration of the
heat generating device 130 of one unit temperature rising at a
time, for example, 0.1.degree. C., when the temperature deviation
rises from T.sub.0 to T.sub.1.
[0095] FIG. 11 is a schematic diagram showing the reference
humidity time relationship (the power of the heat generating device
130 remains unchanged) according to some embodiments of the present
disclosure. The reference humidity time relationship may be
represented by the table or the function curve. As shown in FIG.
11, the humidity time relationship shows the relationship between
the deviation for the measured value of the ambient humidity
relative to the reference ambient humidity deviation ("humidity
deviation") and the power-on duration of the heat generating device
130. Wherein, Ho may be the stable humidity deviation reached by
the heat generating device 130 in the non-operating state. Hi may
be the stable humidity deviation reached by the heat generating
device 130 in the running time for a long time. The time to reach
the stable humidity deviation may be related to factors such as the
type of heat generating device 130, the electric power of the heat
generating device 130, the ambient temperature, and the ambient
humidity, etc. .tau..sub.r0, .tau..sub.r1, .tau..sub.r2,
.tau..sub.r(x-1), .tau..sub.rx may respectively refer to the
power-on duration of the heat generating device 130 of one unit
temperature rising at a time, for example, 0.1 g/m.sup.3, when the
humidity deviation rises from T.sub.0 to T.sub.1.
