Vehicle speed auxiliary prompting system for traffic signal lamp

Abstract

The invention relates to the technical field of traffic, in particular to a vehicle speed auxiliary prompting system for a traffic signal lamp, which comprises a processor, and the output end of the processor is electrically connected with a radar sensor, a tachymeter, a camera, a first LED display screen, a second LED display screen and an alarm. According to the invention, the speed of the vehicle is obtained through the tachymeter and is displayed through the first LED display screen, the processor is used for obtaining the light conversion time of the first traffic light controller and the second traffic light controller for the traffic lights, and the specific speed of the vehicle from the first traffic light to the second traffic light is calculated and then is displayed through the second LED display screen. After the vehicle passes through the first traffic light, a driver can see the specific driving speed of the vehicle, so that the vehicle can smoothly pass through the next traffic light within the passing time of the next traffic light, and therefore, the vehicle can be ensured to pass quickly, and the secondary waiting time of the vehicle can be reduced.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a vehicle speed auxiliary prompting system for traffic signal lights. Background technique [0002] Road traffic lights are a category of traffic safety products, that is, traffic lights. Traffic lights are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Applicable to intersections such as crosses and T-shaped intersections, it is controlled by road traffic signal controllers to guide vehicles and pedestrians to pass safely and orderly. LED (Light Emitting Diode) is a new type of light source developed and produced in recent years. It has low power consumption (current is only 10~20mA), high brightness (light intensity can reach tens of thousands of mcd), and small size (the minimum diameter can reach 3mm) , light weight (a light-emitting diode weighs only a few tenths of a gram), lon...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vehicle speed auxiliary reminder system for traffic lights, which solves the problem that when vehicles are waiting under a red light, the queue length of vehicles will continue to increase with the increase of traffic flow, which will cause congestion and often cause traffic congestion. There is a problem that the vehicles queuing up behind cannot complete the passage in time after the traffic light turns green, and the vehicles need to wait for the second time
