Real Time Detection of Traffic Signal Running State and Remote Alarm for Fault Information at Road Intersection

摘要

This paper developed a set of intelligent system technology of real time detection of traffic signal running state and remote alarm for fault information, aimed at the hot and difficult problems which are caused by traffic signal running faults in Urban Road intersection through the analysis of the mechanism of those faults. This set of system technology determines the state of the traffic light by detecting the sub-voltage signal in the output section of the traffic signal controller terminals. If it finds an abnormal situation, it will alarm remotely automatically. The technology was authorized for the patent of the Chinese invention in 2018.
