Wireless traffic light signal system

Abstract

The invention belongs to the technical field of intelligent traffic, and particularly relates to a wireless traffic light signal system which comprises a traffic signal control system electrically connected with traffic lights, and the traffic signal control system is electrically connected with a traffic control signal wireless transmitting module. The traffic control signal wireless transmitting module comprises a traffic control signal synchronous decoder, a traffic control signal encoder and traffic control signal wireless transmitting equipment which are electrically connected in sequence, and the traffic control signal wireless transmitting equipment is in wireless communication with the traffic control signal wireless receiving equipment in the motor vehicle traffic control signal receiving module; the motor vehicle traffic control signal receiving module comprises traffic control signal wireless receiving equipment, a traffic control signal decoder and a vehicle advanced driving assistance system (ADAS) which are electrically connected in sequence. Traffic light information is sent to the motor vehicle in a wireless mode, traffic light signal information is provided for the unmanned automatic driving motor vehicle, and the safety index of the vehicle driving under severe conditions is improved.

Description

technical field [0001] The invention relates to the technical field of smart traffic, in particular to a wireless traffic traffic light signal system. Background technique [0002] Traffic lights are an important part of traffic signals and an important language of road traffic. Modern urban traffic mainly uses the traffic light control system to regularly switch between red, green, and yellow lights to guide the orderly passage of vehicles and pedestrians, so as to effectively alleviate traffic congestion and traffic safety accidents. Unmanned automatic driving technology has also been introduced into the automotive industry. [0003] The application document with the authorized announcement number CN108877268B discloses an intelligent dispatching method for unmanned intersections without traffic lights, including the following steps: Step 1: Set up traffic managers based on intersections and dispatch areas and divide collision avoidance areas, establish the following The ...

[0004] However, the traffic lights are generally placed on the opposite side of the intersection to facilitate the vehicles passing through the intersection to observe the traffic lights' indication signals to ensure traffic safety. In extreme weather such as smog, the indication signals of traffic lights are easily blocked, which brings hidden dangers to driving
