Abstract
A monitoring system for distributed utilities. A generation
device is provided for converting an available resource to a
desired utility; the resource may be water, in which case the
generator is a purifier for providing potable water, or,
alternatively, the generator may convert a fuel to electrical
power. In either case, an input sensor is provided for measuring
input to the generation device, while an output sensor is provided
for measuring consumption of output from the generation device. The
monitoring system has a controller for concatenating measured input
and consumption of output on the basis of the input and output
sensors. Measured parameters are telemetered to a remote site where
utility generation and use are monitored and may also be
controlled.

TECHNICAL FIELD
[0003] The present invention relates to the field of distributed
utilities, and, more particularly, to distributed water
purification systems and distributed power.
BACKGROUND ART
[0004] In many developing countries and remote areas without power
plants and water purification plants, access to electricity and
safe drinking water is a significant need. Often in such areas,
poor financial resources, limited technical assets, and low
population density does not make it feasible to build power plants
and water purification plants to provide these resources to the
population. In such circumstances, the use of distributed utilities
may provide a solution. Distributed water purification systems,
such as described in U.S. Provisional Application 60/425,820, and
distributed electrical generators, such as diesel-powered internal
combustion generators and generators based on the Stirling cycle,
such as described in U.S. Pat. No. 6,253,550, may be used to
provide electricity and safe drinking water without the expense and
delays associated with building and maintaining utility plants and
the infrastructure required to bring the electricity and safe
drinking water and to its point of use. With such the use of such
distributed utilities, however, comes the need to appropriately
distribute these utilities to the people who need them and to
monitor the operation and correct usage of these systems.
SUMMARY OF THE INVENTION
[0005] In accordance with preferred embodiments of the present
invention, a monitoring system for distributed utilities is
provided. The monitoring system has a generation device for
converting an available resource to a desired utility. The
available resource may be water, in which case the generator is a
purifier for providing potable water. Alternatively, the generator
may convert a fuel to electrical power. In either case, an input
sensor is provided for measuring one or more characteristics of the
input to the generation device, while an output sensor is provided
for measuring consumption or other characteristic of output from
the generation device. The monitoring system has a controller for
concatenating measured input and consumption of output on the basis
of the input and output sensors.
[0006] Where the generation device, in the case, for example, of a
particular utility of a network, is a water purifier, the input
sensor may be a flow rate monitor. The output sensor may be a water
quality sensor including one or more of turpidity, conductivity,
and temperature sensors. On the other hand, where the generation
device is an electrical power generator, the input sensor may
include a fuel consumption rate monitor and the output sensor may
include an electrical usage meter.
[0007] The monitoring system may also have a telemetry module for
communicating measured input and output parameters to a remote
site, either directly or via an intermediary device such as a
satellite, and, moreover, the system may include a remote actuator
for varying operating parameters of the generator based on remotely
received instructions. The monitoring system may also have a
self-locating device, such as a GPS receiver, having an output
indicative of the location of the monitoring system. In that case,
characteristics of the measured input and output may depend upon
the location of the monitoring system.
[0008] In accordance with further embodiments of the invention, a
distributed network of utilities is provided, including sources of
purified water and sources of electrical power. The distributed
network has generators for converting a resource into a useful
utility, input sensors for measuring inputs to respective
generators, output sensor for measuring consumption of output from
respective generators, and a telemetry transmitter for transmitting
input and output parameters of a specified generator. Finally, the
distributed network has a remote processor for receiving input and
output parameters from a plurality of utility generators.
[0009] In accordance with yet another embodiment of the invention,
a method is provided for supplying distributed utilities. The
method has steps of providing a generator to a user, monitoring at
least one index of generator usage to supply a utility, and
charging the user on the basis of the index of generator usage.
[0010] In accordance with other aspects of the present invention,
methods are provided for assembling monitoring systems that monitor
input to, and consumption of output from, a generating device.
These methods include coupling sensors to a controller of the
generating device, and communication channels between the
controller and a monitoring station via a telemetry module.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The foregoing features of the invention will be more readily
understood by reference to the following detailed description,
taken with reference to the accompanying drawings, in which:
[0012] FIG. 1 is a depiction of a monitoring system for distributed
utilities in accordance with embodiments of the present invention;
and
[0013] FIG. 2 is a depiction of a distribution system for utilities
in accordance with embodiments of the present invention.
DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
Monitoring
[0014] Referring first to FIG. 1, preferred embodiments of the
present invention provide for monitoring generation device 10.
Generation device 10 can be any distributed utility generation
device, such as a water purification system, an electrical
generator, or other utility generation device, or a combination of
these. Generation device 10 may typically be characterized by a set
of parameters that describe its current operating status and
conditions. Such parameters may include, without limitation, its
temperature, its input or output flux, etc., and may be subject to
monitoring by means of sensors, as described in detail below.
[0015] In the case in which generation device 10 is a water
purification device, source water enters the generation device 10
at inlet 22 and leaves the generation device at outlet 12. The
amount of source water 25 entering generation device 10 and the
amount of purified water 13 leaving generation device 10 can be
monitored through the use of one or more of a variety of sensors
commonly used to determine flow rate, such as sensors for
determining them temperature and pressure or a rotometer, located
at inlet sensor module 21 and/or at outlet sensor module 11, either
on a per event or cumulative basis. Additionally, the proper
functioning of the generation device 10 can be determined by
measuring the turpidity, conductivity, and/or temperature at the
outlet sensor module 11 and/or the inlet sensor module 21. Other
parameters, such as system usage time or power consumption, either
per event or cumulatively, can also be determined. A sensor can be
coupled to an alarm or shut off switch that may be triggered when
the sensor detects a value outside a pre-programmed range.
[0016] When the location of the system is known, either through
direct input of the system location or by the use of a GPS location
detector, additional water quality tests may be run based on
location, including checks for known local water contaminates,
utilizing a variety of detectors, such as antibody chip detectors
or cell-based detectors. The water quality sensors may detect an
amount of contaminates in water. The sensors can be programmed to
sound an alarm if the water quality value rises above a
pre-programmed water quality value. The water quality value is the
measured amount of contaminates in the water. Alternatively, a shut
off switch may turn off the generation device if the water quality
value rises about a pre-programmed water quality value.
[0017] Further, scale build-up in the generation device 10, if any,
can be determined by a variety of methods, including monitoring the
heat transfer properties of the system or measuring the flow
impedance. A variety of other sensors may be used to monitor a
variety of other system parameters.
[0018] In the case in which generation device 10 is an electrical
generator, either alone or in combination with a water purification
device or other device, fuel enters the generation device from a
tank, pipe, or other means through fuel inlet 24. The amount of
fuel consumed by generation device 10 can be determined through the
use of a fuel sensor 23, such as a flow sensor. Electricity
generated, or in the case of a combined electrical generator and
water purification device, excess electricity generated can be
accessed through electricity outlet 15. The amount of electricity
used, either per event of cumulatively, may be determined by outlet
sensor module 14. A variety of other sensors may be used to monitor
a variety of other system parameters.
[0019] In either of the cases described above, input sensor modules
21 and 23 as well as output sensor modules 11 and 14 may be coupled
to a controller 100, electrically or otherwise, in order to
process, concatenate, store, or communicate the output values of
the respective sensor modules as now described in the following
section.
Communications
[0020] The sensors described above may be used to monitor and/or
record the various parameters described above onboard the
generation device 10, or in an alternative embodiment of the
present invention, the generation device 10 may be equipped with a
communication system 17, such as a cellular communication system.
The communication system 17 could be an internal system used solely
for communication between the generation device 10 and the
monitoring station 20. Alternatively, the communication system 17
could be a cellular communication system that includes a cellular
telephone for general communication through a cellular satellite
system 19. The communication system 17 may also employ wireless
technology such as the Bluetooth.RTM. open specification. The
communication system 17 may additionally include a GPS (Global
Positioning System) locator.
[0021] Communication system 17 enables a variety of improvements to
the generation device 10, by enabling communication with a
monitoring station 20. For example, the monitoring station 20 may
monitor the location of the generation device 10 to ensure that use
in an intended location by an intended user. Additionally, the
monitoring station 20 may monitor the amount of water and/or
electricity produced, which may allow the calculation of usage
charges. Additionally, the determination of the amount of water
and/or electricity produced during a certain period or the
cumulative hours of usage during a certain period, allows for the
calculation of a preventative maintenance schedule. If it is
determined that a maintenance call is required, either by the
calculation of usage or by the output of any of the sensors used to
determine water quality, the monitoring station 20 can arrange for
a maintenance visit. In the case that a GPS (Global Positioning
System) locator is in use, monitoring station 20 can determine the
precise location of the generation device 10 to better facilitate a
maintenance visit. The monitoring station 20 can also determine
which water quality or other tests are most appropriate for the
present location of the generation device 10. The communication
system 17 can also be used to turn the generation device 10 on or
off, to pre-heat the device prior to use, or to deactivate the
system in the event the system is relocated without advance
warning, such as in the event of theft.
[0022] This information can be advantageously monitored through the
use of a web-based utility monitoring system, such as those
produced by Teletrol Systems, Inc. of Bedford, N.H.
Distribution
[0023] The use of the monitoring and communication system described
above facilitates the use of a variety of utility distribution
systems. For example, with reference to FIG. 2, an organization 30,
such as a Government agency, non-governmental agency (NGO), or
privately funded relief organization, a corporation, or a
combination of these, could provide distributed utilities, such as
safe drinking water or electricity, to a geographical or political
area, such as an entire country. The organization 30 can then
establish local distributors 31A, 31B, and 31C. These local
distributors could preferably be a monitoring station 20 described
above. In one possible arrangement, organization 30 could provide
some number of generation devices 10 to the local distributor 31A,
etc. In another possible arrangement, the organization 30 could
sell, loan, or make other financial arrangements for the
distribution of the generation devices 10. The local distributor
31A, etc. could then either give these generation devices to
operators 32A, 32 B, etc., or provide the generation devices 10 to
the operators though some type of financial arrangement, such as a
sale or micro-loan.
[0024] The operator 32 could then provide distributed utilities to
a village center, school, hospital, or other group at or near the
point of water access. In one preferred embodiment, when the
generation device 10 is provided to the operator 32 by means of a
micro-loan, the operator 32 could charge the end users on a
per-unit bases, such as per watt hour in the case of electricity or
per liter in the case of purified water. Either the local
distributor 31 or the organization 30 may monitor usage and other
parameters using one of the communication systems described above.
The distributor 31 or the organization 30 could then recoup some of
the cost of the generation device 10 or effect repayment of the
micro-loan by charging the operator 32 for some portion of the
per-unit charges, such as 50%. The communication systems described
additionally can be used to deactivate the generation device 10 if
the generation device is relocated outside of a pre-set area or if
payments are not made in a timely manner. This type of a
distribution system may allow the distribution of needed utilities
across a significant area quickly, while then allowing for at least
the partial recoupment of funds, which, for example, could then be
used to develop a similar system in another area.
[0025] In view of the foregoing, it will therefore be understood
that the scope of the invention as defined in the following claims
is not limited to the embodiments described herein, and that the
above and numerous additional variations and modifications could be
made thereto without departing from the scope of the invention.
