Intelligent traffic signal lamp control system

Abstract

The invention discloses an intelligent traffic signal light control system, which comprises a ground sense line, a PLC controller, a computer processing system and a signal light. The ground sense line and the signal light are respectively connected to a PLC controller, and the PLC controller is connected to a computer processing system. The line is used to detect the traffic flow information, and the PLC controller is used to obtain the detected traffic flow information from the ground sense line and send the traffic flow information to the computer processing system. The signal lamp sends a control signal, and the signal lamp performs signal display according to the control signal. The invention automatically adjusts the time according to the traffic flow, so that the time in the direction with fewer or no vehicles is automatically shortened, and the time in the direction with more vehicles is automatically changed to effectively relieve the traffic pressure in the city, reduce traffic accidents, save a lot of travel time for the people, and create Bring out more social value.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic equipment, in particular to an intelligent traffic signal lamp control system. Background technique [0002] Due to the development of cities, traffic intersection problems have become more and more serious. Although signal control at traffic intersections has been widely used, good control effects cannot be achieved due to backward control methods. Basically, the traffic lights at intersections are still programmed to be fixed. If you want to adjust the time, you need a special program staff to adjust the program to solve the problem. Over the years, people have conducted systematic research on urban traffic control, and have achieved a lot of research results. The most advanced method is that the traffic police observe the traffic flow at the intersection, and then adjust the green light time by holding the remote control. The quantity is large, and a lot of personnel are needed. ...

On the other hand, the purpose of traffic lights is to provide instructions for the passage of people and vehicles, so as to ensure the normal passage of people and vehicles and avoid accidents. These all require people and vehicles to obey the traffic rules. However, ignoring traffic lights abounds in real life, especially at crossroads. Population crowds cross the road by crossing the red light in groups, forcing normal vehicles to stop and wait, causing trouble to the driver, and easily leading to traffic accidents. The existing solution is to arrange some traffic coordinators at the intersection of traffic lights to maintain order, so as to assist traffic Signal lights, wasting a lot of manpower
