Intelligent traffic signal lamp control system

Abstract

The invention discloses an intelligent traffic signal lamp control system which comprises a traffic flow signal collecting unit, a processor unit connected with the traffic flow signal collecting unit, a wireless sending and receiving module connected with the processor unit, a traffic signal lamp controller in long-distance wireless connection with the wireless sending and receiving module, a displayer connected with the traffic signal lamp controller, and a signal lamp driver used for driving the traffic signal lamp to be lighted. The traffic flow signal collecting unit comprises a microwave detector and a camera. The processor unit comprises an ARM microprocessor, a clock module and a Flash storage module, and the clock module and the Flash storage module are connected with the ARM microprocessor. The microwave detector, the camera and the wireless sending and receiving module are connected with the ARM microprocessor. The intelligent traffic signal lamp control system is simple in structure, reasonable in design, convenient to mount and implement, easy to use and operate, the displaying color and time of the traffic signal lamp can be adjusted automatically according to traffic flow information, practicability is strong, implementation cost is low, using effect is good, and popularization and application are convenient.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic, in particular to an intelligent traffic signal lamp control system. Background technique [0002] With the continuous development of the city, intelligent traffic lights based on traffic flow will be favored by the majority of the people, while traditional traffic lights usually adopt a timing distribution control method, which mainly has three defects: 1. When the lane releases vehicles, the intersection It often happens that vehicles on different phases have the same release time, and the side with more vehicles is prone to vehicle accumulation, causing traffic jams at the next intersection; In a period of time, there is a traffic command blind spot; 3, when the traffic flow at a crossing is very large, the green light time of the crossing cannot be extended automatically, causing the vehicles at this crossing to not pass through completely in one cycle. Contents of the invention ...

When the lane releases vehicles, the intersection It often happens that vehicles on different phases have the same release time, and the side with more vehicles is prone to vehicle accumulation, causing traffic jams at the next intersection; During a period of time, traffic command blind spots appeared; 3. When the traffic flow at the intersection is very large, the green light time at the intersection cannot be automatically extended, resulting in that the vehicles at this intersection cannot pass completely within a cycle
