Intelligent automatic switching device for urban traffic signals

Abstract

The invention discloses an intelligent automatic switching device for urban traffic signals. The device includes a signal lamp base, wherein the signal lamp base is equipped with a signal lamp assembly, the signal lamp assembly is connected with a signal lamp switching system, the signal lamp switching system is used for emitting an instruction for the signal lamp assembly through collecting the road condition information and the environment information, signal switching and intensity conversion of the signal lamp assembly are controlled, the signal lamp assembly is internally further equippedwith an auxiliary power assembly used as a standby power, and the auxiliary power assembly is used for generating power through absorbing external sunlight and extra light of the signal lamp assembly. The device is advantaged in that through detecting the road condition information and the environment information, traffic signal lamp switching and brightness are intelligently adjusted, the electricity utilization rate is improved while efficient pass is guaranteed, self-made clean energy is utilized for providing the auxiliary power for the entire signal lamps, emergent power off can be effectively responded, and accidents can be avoided.

Description

technical field [0001] The invention relates to the technical field of traffic signal equipment, in particular to an intelligent autonomous switching device for urban traffic signals. Background technique [0002] At the intersection, red, yellow, green and three-color traffic lights are hung on all sides. It is a silent "traffic policeman". At the intersection, cars coming from several directions gather here, some have to go straight, some have to turn, who should go first, this is to obey the command of the traffic lights, when the red light is on, it is forbidden to go straight or turn left, without hindering pedestrians In the case of vehicles and vehicles, the vehicle is allowed to turn right; when the green light is on, the vehicle is allowed to go straight or turn; [0003] With the continuous expansion of the city scale and the increasing number of motor vehicles in the city, the pressure on urban road traffic is increasing. In order to ensure road traffic safety a...

AI Technical Summary

Problems solved by technology

[0006] (1) Traditional traffic lights are set at fixed time intervals, and there are still many problems in actual use. For example, safety accidents are easy to occur under road congestion or harsh environmental conditions, and it is not conducive to improving road utilization. , causing more congestion in the city;

[0007] (2) At the same time, when responding to emergencies, the stoppage of traffic lights not only increases the burden on traffic control personnel, but also is prone to traffic accidents, which affects traffic safety
