Embodiment Construction

[0018] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is a detailed description in conjunction with the embodiments and accompanying drawings.

[0019] See figure 1 and figure 2 , The present invention provides a traffic signal control system, including a central management server cluster 10, a communication server 20, and an intersection signal 30. A plurality of the intersection signal 30 is connected to the communication server 20 through a local area network, and the communication server 20 is connected to The central management service area cluster 10. The intersection signal machine 30 is used to execute the command of the central management server cluster 10 to control the work of the intersection signal light, detect the intersection condition in real time and upload it to the central management server cluster 10, the intersection signal machine 30 is installed at the traf...

Abstract

The invention discloses a traffic signal control system which comprises a center management server cluster, a communication server and multiple intersection annunciators, wherein the multiple intersection annunciators are connected with the communication server by virtue of a local area network; the communication server is connected to the center management server cluster; the intersection annunciators are used for controlling intersection signal lamps to work, detecting the intersection situation in real time and uploading the intersection situation to the center management server cluster; the communication server is used for forwarding data of the intersection annunciators and the center management server cluster, and storing data uploaded to the center management server cluster from the intersection annunciators; and the center management server cluster is the control center of the system, and remotely controls the intersection annunciators. According to the traffic signal control system, the traffic interaction can be managed in a zoned mode so as to uniformly control the whole zone. The traffic signal control system can be quickly restored when having faults, and can conveniently provide various modes of intersection state inquiry. Furthermore, coordination control can be carried out on a plurality of intersections.

Description

Technical field [0001] The invention relates to the field of signal control, in particular to a traffic signal control system. Background technique [0002] The existing traffic signal lights are generally controlled by the intersection signal and run according to the set fixed parameters, but the control of the intersection signal lacks a remote control mechanism. If the traffic signal needs to be adjusted temporarily, it is often necessary to have the traffic police on-site to the intersection. The semaphore is temporarily adjusted to control the light color and time of the signal light, and the on-site adjustment cannot be uniformly deployed for multiple intersections. Due to the lack of an overall analysis of the signal lights at different intersections, the traffic flow efficiency of on-site adjustment of the signal lights is low. If the intersection semaphore fails, the control parameters of the signal light in the intersection semaphore will be lost, and resetting will ta...
