Problems solved by technology

Therefore, the detection cycle is long, the information feedback speed is slow, and the detection cost is high, which can no longer meet the increasing needs of transportation in today's society.
To do a good job in traffic signal system fault detection, we must first understand the normal operation of the traffic signal system and the main characteristic information under various faults. At present, the traffic department and manufacturers lack research and statistics on the above information, and it is difficult to provide targeted faults. Monitoring program
If designated personnel are assigned to monitor by regular inspection, although the fault information can be detected simply and directly, for areas with complex traffic conditions and a large number of signal lights, this method is inefficient, high in cost, and cannot satisfy accurate positioning

Abstract

The invention discloses a road traffic signal light fault diagnosis device comprising a detector fault diagnosis module, a signal light fault diagnosis module, a power supply system diagnosis module, a wireless communication module, a sound and light alarm module, and a human-machine interaction module. The modules are independent from each other. The software and hardware modules of the device are effectively separated. In timing plan analysis diagnosis, the device uses a detector for information analysis, fully considers the actual status of an intersection, and improves the reliability of diagnosis. The device realizes remote diagnosis, so that a technician can modify configuration and parameters of the device through a remote 4G wireless network and do analysis and processing of data through a wireless network without being on site.

Description

technical field [0001] The invention relates to a traffic signal lamp fault detection device, which can reduce traffic congestion and traffic accidents caused by traffic signal faults based on the real-time analysis and diagnosis of traffic signal control information by an information collection device. 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 urgent problems for the transportation department. The accurate information of the traffic signal system is the basis for ensuring smooth and safe highway and road traffic. Therefore, the detection and fault diagnosis of the signal system is particularly critical. In this context, as the traffic signal system maintains stability and the requirements for safe work continue to increase, higher requirements are put forward for the continuous real-time de...
