Embodiment 1
[0029]Referring to Figure 1, an automatic fault detection and processing system for traffic lights, including traffic lights, a current and voltage detection module, a protection control module, a signal light drive control module, a signal light processor, a signal central processing unit, and a traffic monitoring center; the current The input end of the voltage detection module is connected to the output end of the traffic signal light, and the output end is connected to the input end of the signal light processor; the input end of the signal light processor is connected to the power module, and the output end is respectively connected to the input end of the signal light driving control module and the protection control module The input end is connected; the input end of the protection control module is connected with the output end of the signal light driving control module, and the output end is connected with the traffic signal light input end; the signal light processor i...
Embodiment 2
[0035] Referring to Figure 1, a method for automatic fault detection and processing of traffic lights, including an automatic fault detection system, a fault processing system, and a fault information reporting system, the automatic fault detection system includes a traffic signal light, a current and voltage detection module, a signal light processor, a fault The processing system includes a signal central processor, a signal light processor, a protection control module, and a traffic signal light, and the fault information reporting system includes a signal light processor, a signal light central processor, and a traffic monitoring center; the method includes the following steps:
[0036] (1) Use the current and voltage detection module to detect whether the traffic lights are working normally. When the signal lights fail, the central processor of the signal machine sends a degraded control command to the signal light processor to drive the traffic lights to start software yel...
