A kind of traffic signal light fault intelligent detection, alarm system and method

Abstract

The invention discloses an intelligent detection and alarm system for traffic signal lights, which includes a signal light working state collector, a signal light controller working state collector, a central server / wireless mobile data transmitter, and the signal light working state collector is connected to the signal light to collect the current working state of the signal light status, and transmit it to the working status collector of the signal lamp controller; the working status collector of the signal lamp controller is set between the signal lamp and the connection line of the signal lamp controller, collects the output signal of the signal lamp controller, and compares it with the current working status of the received signal lamp; The working state collector of the signal light controller is connected to the central server through the data communication network, and the fault information is sent to the user after processing, or the working state collector of the signal light controller is connected with the wireless mobile data transmitter, and the fault information is sent to the user. The invention improves the accuracy and real-time performance of signal lamp fault detection and alarm, enhances detection means, and reports signal lamp fault more comprehensively.

Description

technical field [0001] The invention relates to the technical field of traffic information control, in particular to a traffic signal light failure intelligent detection and alarm system and method. Background technique [0002] Nowadays, after the failure of the traffic signal light occurs, the maintenance unit generally obtains the failure information through the following ways: [0003] 1. Traffic signal light controller self-inspection [0004] The development of the traffic signal light controller generally goes through the following stages: single-point fixed-period stage-single-point adaptive stage-network control stage-network coordination stage. The function has also changed from a single time-period timing timing of the green light time of each direction signal light at a single intersection to regional signal machines to coordinate and control traffic flow, and the corresponding additional functions are also changing with each passing day. At present, all networ...

Problems solved by technology

The detection of the signal lamp controller can only detect the presence or absence of voltage and current on the cable, but cannot detect the failure of the signal lamp light-emitting unit power supply control circuit on the signal lamp and the light-emitting unit formed by the LED arrangement.

Traffic lights working outdoors are greatly affected by environmental factors and the quality of electronic parts, and various problems emerge in an endless stream. The detection method of the power-on signal of the cable on the output circuit by the controller alone is not enough to accurately respond to the work of the on-site signal lights. The actual situation, so the effect of the independent detection method of the signal light controller is not satisfactory
