Abstract

The invention relates to the technical field of urban rail transit equipment, in particular to an LED lighting system with a cold wire supervision function. It includes an LED power supply circuit and a single-chip microcomputer U1; the LED power supply circuit includes a first connection point 1 and a second connection point 2 for collecting current in the LED power supply circuit, and the LED power supply circuit also includes a LED power supply circuit for collecting The third connection point 3, the fourth connection point 4 and the fifth connection point 5 of the medium voltage, the first connection point 1, the second connection point 2, the third connection point 3, the fourth connection point 4 and the fifth connection point Point 5 includes connecting with single-chip microcomputer U1 respectively. Through the research on the intelligent LED lighting system with the cold wire supervision function, the present invention can monitor the status of the lighting filament of the outdoor signal lamp in real time, and transmit the collected information back to the indoor terminal through the cable, and the terminal performs data retention, fault prompting, and early judgment The deterioration trend of the filament state and electrical characteristics greatly reduces the number of lights-off failures of the signal machine.

Description

technical field [0001] The invention relates to the technical field of urban rail transit equipment, in particular to an LED lighting system with a cold wire supervision function. Background technique [0002] The urban rail transit lines using the ATC system that have been opened in China have added requirements for the cold wire supervision function of the signal machine in the technical conditions and standards in recent years, but there are no actual products to provide technical support and implementation in actual projects. [0003] With the rapid development of rail transit projects, the existing signal application technology can no longer meet the operational needs. [0004] E.g: [0005] As a backup redundant device, the high-speed rail signal machine is usually closed. When the main equipment fails, the signal machine can be used as a substitute. Therefore, the signal machine should be able to regularly and automatically detect the main and auxiliary lights in the...
