Intelligent traffic signal control system

Abstract

The invention discloses an intelligent traffic signal control system. The intelligent traffic signal control system comprises a signal control platform, a signal lamp terminal and a police intelligentterminal, wherein the signal lamp terminal comprises a control gateway and a display device; the control gateway reports state information of the signal lamp terminal to the signal control platform,receives a traffic signal timing scheme issued by the signal control platform, and drives the display device to display traffic signals; the police intelligent terminal takes over the signal lamp terminal through the signal control platform; and the signal control platform receives registration of the signal lamp terminal and the police intelligent terminal, issues the traffic signal timing schemeto the signal lamp terminal, or receives a taking-over request of the police intelligent terminal, so that the police intelligent terminal takes over the signal lamp terminal. According to the intelligent traffic signal control system, the signal lamp terminal and the signal control platform are in two-way communication, and the signal control platform timely masters the traffic signal conditionand the road condition of an intersection and performs real-time intervention.

Description

technical field [0001] The invention belongs to the technical field of traffic signal control, in particular to an intelligent traffic signal control system. Background technique [0002] As cities continue to expand and urban roads become more and more complex, traffic signal control systems are becoming more and more important. How to comprehensively apply a variety of technologies to make vehicle driving and road navigation intelligent, so as to alleviate road traffic congestion, reduce traffic accidents, improve road traffic environment, save traffic energy, reduce driving fatigue and other functions, has become an urgent problem in urban traffic. One of the key propositions of the management system. [0003] At present, with the development of communication technology and big data technology, the traffic signal control system is gradually developing towards networking and intelligence. Networking means that the signal machine is connected to the signal control platfor...

Problems solved by technology

For example, the signal machine is a kind of special equipment, which is expensive, so that the traffic signal control system cannot cover all road intersections in cities and villages; from the perspective of system reliability, the signal machine is a "single point" that is prone to failure. fault, the traffic at the entire intersection is paralyzed; the current traffic signal lights can only be a special display device, and the information that can be displayed is very limited; the connection between the signal machine and the signal light is based on AC220V to realize power supply and communication functions, and the central signal control platform is difficult Perceive the operating status of the signal light (you need to add additional communication channels such as serial ports, wireless networks, etc. to perceive); it is inconvenient for the traffic police to temporarily take over the signal control system at the intersection, and you need to carry a special key to open the signal machine control cabinet and follow the operation instructions. deal with
