Abstract

A wireless vehicle reversal monitoring device comprised of an image acquisition unit and an image control display processing system 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.

Claims

1. A wireless vehicle reversal monitoring device comprised of an image acquisition unit and an image control display processing system, of which:

The said image acquisition unit consists of an observation camera, a high frequency transmitter, and a controller;

the said controller has control over the switching on of the said observation camera, control over the switching on of the said high frequency transmitter, and control over the channel selector of the said high frequency transmitter;

The said image control display processing system consists of a high frequency receiver, a multi-scanning video frequency amplifier controller, and a display;

in addition to having control over the switching on of the said high frequency receiver and the channel selector of the said high frequency receiver, the said multi-scanning video frequency amplifier controller 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 said display;

When a vehicle equipped with the present invention is in reverse gear and backing up, a vehicle power supply signal is inputted to the said controller and the said multi-scanning video frequency amplifier controller, following which power is switched on to the said observation camera and the said high frequency transmitter, the said observation camera next provides images that show the view to the rear of the vehicle and sends the video signals to the said high frequency transmitter, and then the said high frequency transmitter propagates the video signal wirelessly via radio frequency waves;

the said high frequency receiver detects the video signals containing images at the rear of the vehicle and relays it to the said multi-scanning video frequency amplifier controller and after the said multi-scanning video frequency amplifier controller filters out interference artifacts and amplifies the images taken at the rear of the vehicle, the video signals are sent to the said display.
