Problems solved by technology

[0003] 1. The communication method is single, once the communication method is damaged, it will affect the operation of the entire system;
[0004] 2. The setting method of the traffic signal is rigid, and generally there is only a single setting method;
[0005] 3. The system is poor in anti-surge impact, anti-period drop, anti-group pulse interference, and anti-static interference;
[0006] 4. The human-computer interaction of the traffic signal machine is inconvenient;
[0007] 5. Poor system scalability

Abstract

The invention relates to an urban traffic signal control system which comprises: a center control subsystem, a monitoring computer, a GIS geographic information subsystem, a traffic monitoring control interface, a data communication controller, traffic signal machines, a traffic signal acquisition device and a traffic signal display device. The center control subsystem is respectively connected with the monitoring computer, the GIS geographic information subsystem, the traffic monitoring control interface and the data communication controller. The data communication controller is connected with the traffic signal machines through a communication module. The traffic signal machines are respectively connected with the traffic signal acquisition device and the traffic signal display device. Compared to the prior art, the system has advantages of various communication modes, easy setting and the like.

Description

technical field [0001] The invention relates to a traffic signal control system, in particular to a centralized urban traffic signal control system. Background technique [0002] Urban traffic centralized and coordinated control system (UTCS, Urban Traffic Control System) is one of the important components of modern urban intelligent traffic system (ITS), which is mainly used for the control and intelligent management of urban road traffic. The existing urban traffic signal control system has the following defects [0003] 1. The communication method is single, once the communication method is damaged, it will affect the operation of the entire system; [0004] 2. The setting method of the traffic signal is rigid, and generally there is only a single setting method; [0005] 3. The system is poor in anti-surge impact, anti-period drop, anti-group pulse interference, and anti-static interference; [0006] 4. The human-computer interaction of the traffic signal machine is i...
