WebGIS (Web Geographic Information System)-based traffic light fault supervision system

Abstract

The invention discloses a WebGIS (Web Geographic Information System)-based traffic light fault supervision system. The system mainly comprises a traffic light information collection terminal, a supervision center, a monitoring user side and a maintenance user side which realize two-way information communication by virtue of a mobile communication network and an Internet. The traffic light information collection terminal periodically collects status information of traffic lights and sends the fault information to the supervision center in a text message manner, and the supervision center analyzes and processes the fault information and provides the real-time fault information of the traffic lights in a WebGIS map manner for the monitoring user side logged by a browser, and can automatically perform maintenance task assignment, optimization and calculation after receiving the new fault information, and automatically send a maintenance task command to the maintenance user side after being confirmed by a monitoring personnel. The system can be used for realizing the real-time monitoring and timely maintenance of the traffic lights and increasing the non-fault working time of the traffic lights, thereby further ensuring the safety and smoothing of road traffic..

Description

technical field [0001] The invention belongs to the technical field of traffic lights, and in particular relates to a traffic light failure monitoring system. Background technique [0002] With the development of social economy, urban traffic problems have attracted more and more attention. The coordination of the relationship between people, vehicles and roads has become one of the problems that the transportation department needs to solve urgently, and the normal operation of traffic lights is the basis for ensuring smooth and safe road traffic. With the continuous increase of the number of various vehicles, the continuous real-time monitoring of the working conditions of traffic lights has put forward higher requirements. [0003] Occasionally, traffic lights fail due to equipment reliability and the operating environment. General failures of traffic lights, such as off-light, mixed color conflicts, lack of dot matrix and garbled characters, etc., will provide wrong tra...

AI Technical Summary

Problems solved by technology

[0005] Through the research on the existing technology, it is found that the traffic light monitoring system in the prior art only has the function of collecting controller data, and cannot automatically monitor the traffic light failure, nor has the maintenance management function for the traffic light failure, and cannot immediately Assign personnel to carry out maintenance; and the monitoring center adopts a stand-alone working mode. The monitoring computer must first install monitoring software to display the traffic light situation. When replacing the monitoring computer, it is very time-consuming and difficult to meet the current requirements for rapid response to traffic light failures.
