Description

technical field [0001] The invention relates to a traffic signal control network, especially a traffic signal control system with remote control capability. Background technique [0002] With the development of modern cities and the increasing number of vehicles, the problem of urban traffic congestion is becoming more and more serious. Especially during the peak traffic period, the intersection has become a frequent area where various motor vehicles and non-motor vehicles compete with each other and cause various traffic accidents. , but also to limit traffic flow. Therefore, it is an important means to solve the above problems to establish a traffic signal control system to direct the traffic so that the traffic is orderly and the traffic efficiency is improved. Existing traffic control systems, such as digital display traffic signal light control systems, include a traffic signal control machine and a digital display that contain a signal control module. In the signal co...

Problems solved by technology

However, in the actual traffic control command of the existing traffic signal control system, because the traffic signal control machine only includes the signal control module, its control mode is fixed, and it cannot adapt to the special circumstances that occur at traffic intersections. The routine control of stopping traffic lights requires human intervention and command by the traffic police. For example, a traffic policeman needs to use gestures to command the vehicle to stop at the scene, and another traffic policeman controls the signal light console set in the traffic police booth according to the situation on the spot. Carry out manual control and cooperate with the traffic police on the scene

Such a control method not only has low control efficiency, but also is rigid and inconvenient to operate.

At the same time, the existing traffic signal control system is susceptible to external interference in command, and also wastes human resources
