Traffic signal remote control system

Abstract

The invention relates to the technical field of traffic equipment, and discloses a traffic signal remote control system. The system comprises a terminal control device which is used for controlling intersection annunciators of all intersections in the area; and a communication server which is used for communicating the multiple intersection annunciators with the terminal control device; each intersection annunciator is in communication connection with a signal lamp, the signal lamps are specifically a red lamp for forbidding passing, a street lamp allowing passing and a yellow lamp used for prompting, and the red lamp, the green lamp and the yellow lamp are all in communication connection with the intersection annunciators through a time control device. When emergency situations such as fire alarms or passing of important vehicles like ambulances occur, traffic polices can control the intersection annunciator in the area where the traffic polices are located through the handheld remotecontroller, and then the red light or the green light is changed for route changing, so that the important vehicles can pass through the traffic light preferentially.

Description

technical field [0001] The invention relates to the technical field of traffic equipment, in particular to a traffic signal remote control system. Background technique [0002] Traffic signal refers to the place where traffic separation cannot be realized at road intersections. It is used to allocate traffic flow to traffic flow in time. Traffic command measures are divided into traffic signal lights, traffic signs, traffic markings and traffic police commands. The role of traffic signals is to scientifically allocate the right of way of vehicles and pedestrians on the road, so that they can pass in an orderly and smooth manner. China implements unified road traffic signals. [0003] Since most of the current signal lights are controlled by signal machines, the traffic command department controls the signal lights through the control device, but in practice, there are often problems with the signal lights at intersections, which requires maintenance of signal lights or sign...

AI Technical Summary

Problems solved by technology

[0003] Since most of the current signal lights are controlled by signal machines, the traffic command department controls the signal lights through the control device. However, in practice, there are often problems with the signal lights at intersections. Sexual congestion and congestion, and when there is an emergency, such as an ambulance or a fire alarm that encounters a red light, it will affect the rescue time. At this time, it is necessary for the traffic police on duty to report the intersection to the command department and control the intersection from the control terminal The time of the signal lights, so there is a problem of time difference
