Automobile tail traffic signal display system

Abstract

The invention relates to an automobile tail traffic signal display system. The automobile tail traffic signal display system comprises a radio-frequency signal output module and a signal receiving module, wherein the radio-frequency signal output module outputs traffic light signals and is installed at the position where traffic lights are located, and the signal receiving module is installed on an automobile. The system further comprises a signal selection module, a signal processing module and a control module, wherein the signal selection module is used for recognizing the driving direction of the automobile and determining that radio-frequency signals in which driving direction need to be selected, the signal processing module is used for decoding the signals sent by the signal selection module, and the control module is used for receiving the signals sent by the signal processing module and controlling color changing of the automobile tail traffic lights. The system can be triggered within a determined range near the traffic lights and display corresponding traffic information in real time at the automobile tail. The system is simple and low in cost and does not influence the overall attractiveness and waterproofness of the automobile.

Description

technical field [0001] The invention relates to a traffic safety device, in particular to a traffic signal display system installed at the rear of a vehicle. Background technique [0002] At the present stage, at the traffic lights, when a small car follows a large vehicle such as a bus, it is easy to follow the car and run through the red light because it cannot see the traffic light signal ahead. Some existing patents have proposed solutions to this problem, such as a car that can provide a field of view for the rear car disclosed in Chinese patent (201410293996. , but it is not practical in practice. First of all, adding a display screen at the rear of the car increases the cost. Secondly, adding a display screen will limit the use of the vehicle. It is not practical for container trucks. Another example is a freight car. The car body is often scratched and bumped, and the safety of the display screen is a big problem. [0003] Another example is a Chinese patent (20151...
