Description
BACKGROUND OF THE INVENTION
[0001] 1) Field of the Invention
[0002] The invention herein relates to a wireless vehicle reversal
monitoring device comprised of an image acquisition unit and an
image control display processing system that provides a wireless
vehicle reversal monitoring device of higher product utility and
increased safety when a vehicle so equipped is in the process of
reversing.
[0003] 2) DESCRIPTION OF THE PRIOR ART
[0004] As is well-known, the rear-view mirrors at the left and
right sides of a vehicle are utilized to assist the driver while a
vehicle is reversing; however, the field of vision of the rear-view
mirrors is limited and due to the numerous blind angles present,
vehicle reversal based on such a limited field of vision can be
quite dangerous; to improve the conventional rear-view mirror-based
vehicle reversal model, vehicle reversal monitoring devices were
introduced on the market; the first generation reversal monitoring
devices were hard-wired installations and users had to expend
considerable effort concealing cables which, furthermore, spoiled
the appearance of vehicle interiors; moreover, vehicle reversal
monitors mounted on vehicle exteriors were often damaged and when
the conventional wired-type vehicle reversal monitoring devices
were utilized on trailered vehicles and other similar heavy
vehicles, every separation of the tractor truck from the trailer
required the reinstallation of wiring several dozen meters in
length which caused great user difficulty. To overcome the existent
shortcomings of the conventional product, while increasing
utilization convenience and practicality, the inventor of the
invention herein addressed the said shortcomings based on many
years of experience gained while engaged in the related specialized
fields by conducting research and development as well as repeated
testing and refinement to ensure that the invention herein was
capable of optimal utility, which culminated in the completion of
the wireless vehicle reversal monitoring device of the present
invention.
SUMMARY OF THE INVENTION
[0005] Therefore, the primary objective of the invention herein is
to provide a wireless vehicle reversal monitoring device that
eliminates the inconveniences and perplexities of wired
installations. In addition, the present invention is theft-proof in
that it is easily uninstalled, ensures increased safety during
vehicle reversal, and is of greater product value.
[0006] To enable the examination committee to further understand
the structural characteristics and technological content as well as
the advantages and innovative features of the invention herein, the
brief description of the drawings below is followed by the detailed
description of the invention herein.

DETAILED DESCRIPTION OF THE INVENTION
[0011] The invention herein provides a wireless vehicle reversal
monitoring device comprised of an image acquisition unit and an
image control display processing system, wherein the image
acquisition unit, referring to FIG. 1, consists of an observation
camera 1, a high frequency transmitter 2, and a controller 3; the
said controller 3 has control over the switching on of the
observation camera 1, control over the switching on of the high
frequency transmitter 2, and control over the channel selector of
the high frequency transmitter 2; (the said high frequency
transmitter 2 is a commonly used conventional wireless transmission
system and, furthermore, the observation camera 1 is a commonly
used conventional video camera system, the principles and
utilization of which are familiar to those skilled in the related
technologies).
[0012] Referring to FIG. 2, the image control display processing
system consists of a high frequency receiver 4, a multi-scanning
video frequency amplifier controller 5, and a display 6; in
addition to having control over the switching on of the high
frequency receiver 4 and the channel selector of the high frequency
receiver 4, the said multi-scanning video frequency amplifier
controller 5 is capable of automatically adapting to the different
video transmission output of various video signal sources,
enhancing inputted images, and eliminating interference artifacts
to provide an optimal signal source for the display 6.
[0013] As indicated in FIG. 3, when a vehicle equipped with the
present invention is in reverse gear and backing up, a vehicle
power supply signal is inputted to the controller 3 and the
multi-scanning video frequency amplifier controller 5, following
which power is switched on to the observation camera 1 and the high
frequency transmitter 2, the observation camera 1 next provides
images that show the view to the rear of the vehicle and sends the
video signals to the high frequency transmitter 2, and then the
high frequency transmitter 2 propagates the video signal wirelessly
via radio frequency waves. The high frequency receiver 4 detects
the video signals containing images at the rear of the vehicle and
relays it to the said multi-scanning video frequency amplifier
controller 5 and after the said multi-scanning video frequency
amplifier controller 5 filters out interference artifacts and
amplifies the images taken at the rear of the vehicle, the video
signals are sent to the display 6 so the driver can clearly see
images showing the view at the rear of vehicle to thereby augment
vehicle reversing safety.
[0014] Referring to FIG. 4, the flow chart illustrating the
operation of the multi-scanning video frequency amplifier
controller 5, the said multi-scanning video frequency amplifier
controller 5 also has an image filtering and amplifying circuit 51
as well as a power signal control circuit 52 such that when the
vehicle is not in the process of reversal, it is capable of
receiving multimedia video imaging signals from other sources in
the vehicle and functions as a signal amplifier; when the vehicle
is placed in reverse and the vehicle reversal power signal is
inputted, the high frequency receiver 4 is immediately switched on,
processing is re-directed to video signals sourced from the rear of
the vehicle, and rear-of-vehicle imaging is sent to the display
6.
[0015] Following the assembly of the said structure that provides
for a wireless vehicle reversal monitoring device, when compared to
the laborious wired installation utilized by the conventional
technology, the wireless separate-type arrangement of the image
acquisition unit and the image control display processing system of
the present invention is more convenient and practical to install.
In addition, when a vehicle so equipped is not in the process of
reversing, the invention herein functions as a signal amplifier for
other multimedia video imaging signal sources and, furthermore, is
theft-proof in that it is easily uninstalled, ensures increased
safety during vehicle reversal, and is of greater product
value.
[0016] The preceding detailed description elaborates one feasible
embodiment of the invention herein; however, the said embodiment
shall not be construed as a limitation of the scope and claims of
the present invention and, furthermore, all adaptations and
modifications based on technological spirit of the present
invention shall remain within the scope and claims of the invention
herein.
[0017] In summation of the foregoing section, since the invention
herein is of an original spatial arrangement and capable of
achieving even greater utility and performance as well as higher
practical value and, furthermore, similar or identical product
disclosures have not been observed on the market, the invention
herein is submitted to the examination committee for review in
application for the granting of the commensurate patent rights.
