Abstract

The invention relates to the urban rail transit equipment technology field and especially relates to an LED lighting system with a cold filament monitoring function. The system comprises an LED powersupply circuit and a single-chip microcomputer U1. The LED power supply circuit comprises a first connection point 1 and a second connection point 2 which are used for collecting a current in the LEDpower supply circuit. The LED power supply circuit further comprises a third connecting point 3, a fourth connecting point 4 and a fifth connecting point 5 which are used for collecting a voltage in the LED power supply circuit. The first connecting point 1, the second connecting point 2, the third connecting point 3, the fourth connecting point 4 and the fifth connecting point 5 are connected with the single-chip microcomputer U1. In the invention, the intelligent LED lighting system with the cold filament monitoring function is researched; a lighting filament state of an outdoor signal lampcan be monitored in real time, acquired information is transmitted back to an indoor terminal through a cable, a terminal carries out data retention and fault prompt, a deterioration trend of a filament state and an electrical characteristic is pre-judged in advance, and the number of light-off faults of a signal machine is greatly reduced.

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 existing domestic urban rail transit lines that use the ATC system have been added to the technical conditions and standards in recent years to supervise the function of the cold wire of the signal, but there is no actual product to provide technical support and implementation in the actual project. [0003] With the rapid development of rail transit projects, the existing signal application technology can no longer meet operational needs. [0004] E.g: [0005] The high-speed rail semaphore is usually off as a backup redundant device. When the main equipment fails, the semaphore can be activated as a substitute. Therefore, the semaphore should be able to periodically automatically detect the main and auxiliary lights in the standby state to ensure that it is used In good c...
