Method and system for traffic light signal control based on wifi (Wireless Local Area Network) signal

Abstract

The invention relates to a method and a system for traffic light signal control based on wifi (Wireless Local Area Network) signal. The system comprises a monitoring center computer and a traffic light controller, wherein the monitoring center computer is used for installing traffic light operation scheme developing software and traffic light monitoring software on the computer; the traffic light operation scheme developing software is capable of deploying street lamps according to the site condition of a traffic crossing, developing a traffic light operation scheme in a graphic interface manner and carrying out simulated running, and is also capable of transforming the developed traffic light operation scheme into data files recognized by the traffic light controller; and the traffic light monitoring software is capable of displaying the information of each traffic crossing transmitted through the Internet in real time. In the system for traffic light signal control, the traffic light controller and a monitoring center carry out two-directional communication by means of a universal wireless network so that the monitoring center can remotely control and monitor the operation of the traffic light and simultaneously the purposes of remotely developing and amending the traffic light operation scheme can be reached.

Description

technical field [0001] The present invention relates to a traffic light control system, in particular to an intelligent traffic light control method and system based on wifi network wireless connection, which are used for traffic light network control. Background technique [0002] With the increasing traffic flow in the city, the urban traffic pressure is also increasing, which puts forward higher requirements for the traffic light control system. Most of the existing traffic light controllers are managed independently, using single-point control mode, without real-time communication with the traffic management center. With single-point control, it is difficult to modify the traffic light operation scheme or check the current traffic light signal status, let alone coordinate the traffic at the relevant intersections. At present, there are traffic light control systems with networked communication, and most of them are based on wired or dedicated wireless signals. There ...

AI Technical Summary

Problems solved by technology

In this communication system, a dedicated wireless network is used, which only realizes one-way communication between the monitoring center and the traffic light controller, so that the monitoring center cannot remotely monitor the operating status of the traffic light

At the same time, in this device, it is only used to modify the designed traffic light operation scheme, and cannot remotely develop the traffic light operation scheme
