Method and system for remote fault detection of traffic signal controller

Abstract

The invention discloses a method and a system for remote fault detection of a traffic signal controller. The system comprises a system consisting of a fault detection module arranged in a box body of the traffic signal controller and a server arranged in a traffic management center, and a program of module operation, wherein the fault detection module is connected with a main controller of the traffic signal controller through an internal bus, performs real-time receiving and processing on state information acquired by the main controller, regularly sends the state information to the remote server according to a format if the normal operation of the controller is detected, and detects the deviation of state parameters for advance accident alarm at the same time; and the fault detection module automatically alarms the remote server through a network if the abnormal state of the controller is detected, submits detailed fault information at the same time, and provides remote connection and state query services. The method and the system can timely and automatically notify related departments for the treatment under the condition of the damaged traffic signal controller, support the real-time state detection and remote fault diagnosis of the signal controller, and can be widely used for guaranteeing traffic safety.

Description

technical field [0001] The invention belongs to the technical field of traffic information control, and relates to a remote fault detection method and system of a traffic signal controller. Background technique [0002] Because the traffic signal controller is installed at the intersection of the city and the working environment is harsh, it will be subject to various interferences in actual work, and it is prone to failures, such as signal lamp failures, bidirectional thyristor failures, program memory failures, and green signal conflict failures. If the traffic signal controller at an important intersection breaks down, it will easily cause traffic jams or even serious traffic accidents. When the traffic signal controller suffers from unpredictable or irreversible natural disasters (such as lightning strikes, power outages, flooding), the traffic control department can get an alarm in time, and can obtain detailed information on the traffic signal controller failure, and d...
