Traffic light live wire open circuit monitoring device, traffic light live wire open circuit monitoring circuit, and monitoring method

Abstract

The invention provides a traffic light live wire open circuit monitoring device, a traffic light live wire open circuit monitoring circuit, and a monitoring method. In the case of normal working of traffic lights, the monitoring device is in a real-time monitoring state with low power consumption, and does not interfere the normal work of a traffic light, once a line fault occurs, the monitoring device locates an open circuit line in time, and supplies power to the traffic light encountering the open circuit fault in the line by using a standby power supply so as to avoid traffic chaos, congestion and even traffic accidents generated accordingly. Since the wireless communication technology is adopted, the normal work of the traffic light can be guaranteed without temporary external line after the open circuit of the live wire of the traffic light. In addition, the monitoring device can also upload the line fault information to a monitoring platform in real time to realize remote monitoring.

Description

technical field [0001] The invention relates to the field of traffic signal lamp monitoring, in particular to a traffic signal lamp live wire open circuit monitoring device, monitoring circuit and monitoring method. Background technique [0002] The current traffic lights are all operated by the centralized control of the signal machine. The lines between the signal machine and the signal light may be damaged due to road damage, insects and other animals biting the wires, and the aging of the wires. Abnormal phenomena such as lighting or failure will not only cause traffic paralysis, but also make troubleshooting very difficult. At present, to solve this kind of problem, it is necessary to arrange staff to detect and check the signal machine and signal light at the same time, which is time-consuming and labor-intensive. [0003] It can be seen that how to monitor the status of traffic lights in real time, and solve the problem of signal light line failure in time after the ...
