System and method for automatically detecting and processing fault of traffic signal lamp

Abstract

The invention relates to a system and method for automatically detecting and processing a fault of a traffic signal lamp. The system comprises the traffic signal lamp, a current and voltage detecting module, a protection control module, a signal lamp drive control module, a signal lamp processor, a signal machine central processing unit and a traffic monitor center. When the signal lamp breaks down, a signal machine does not independently drive a yellow lamp to achieve yellow lamp flashing control by simply cutting off a signal lamp power supply any more, a degradation control instruction is sent to the signal lamp, short-time software is started for yellow lamp flashing control, meanwhile, the fault signal lamp is automatically detected to start a second-level protection control mode on the signal lamp, fault information is sent to the last level, and finally normal signal control over a whole intersection is achieved. The second-level protection control module for signal lamp control achieves the backup of the signal lamp control function, stability and reliability of signal lamp control are effectively improved, and the influence of long-time yellow lamp flashing control on traffic is avoided well.

Description

technical field

[0001] The invention relates to the field of traffic signal machines, in particular to a system and method for automatic fault detection and processing of traffic signal lights. Background technique

[0002] With the increase of urban road construction and the number of motor vehicles, road traffic problems have increasingly become the focus of social attention. The control of signal lights separates conflicting traffic flows in time, and through the method of time-sharing release, the safety and order of traffic at road intersections is guaranteed, and the traffic efficiency is improved. When the signal lights fail, it is easy to cause traffic jams at traffic intersections, and even cause traffic accidents. The control of visible signal lights plays an extremely important role in alleviating road traffic problems. However, signal lights are installed at traffic intersections and are easily affected by natural factors, and they are in working condition for ...
