Problems solved by technology

For occasions where a small number of AC filament conversion relays are used, the method of manual disassembly and detection is feasible to a certain extent, but for the occasions where AC filament conversion relays are widely used, frequent and large-scale disassembly and maintenance of AC filament conversion relays will affect the system. Caused a great impact, greatly consumed manpower and material resources, and the detection cycle was long and the process was cumbersome

Abstract

An AC filament conversion relay online detection system is composed of an MCU, an on-off execution unit, an acquisition unit, a wireless remote data transmission unit, a cloud server and a monitoringplatform. The system is simple in structure, and is directly installed in an AC filament conversion relay circuit. The system is high in anti-interference performance, long in transmission distance, high in transmission speed, good in instantaneity and accurate in operation coordination, remote fault diagnosis and fault monitoring of the alternating-current filament conversion relay can be achieved on the premise that normal work of the alternating-current filament conversion relay is not affected, and normal operation of a system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of relay detection, in particular to an on-line detection system and method for an AC filament conversion relay. Background technique [0002] The normal operation of the AC filament conversion relay provides a guarantee for the normal operation of the railway colored light signal machine system. According to the requirements of the national standard, in order to ensure the stability of the railway color light signal machine, the AC filament conversion relay should be regularly overhauled. [0003] Most of the traditional detection methods for AC filament conversion relays are to dismantle the AC filament conversion relays, install spare qualified AC filament conversion relays, take the AC filament conversion relays to be tested back to the production workshop, and use special AC filament conversion relay testing equipment for testing. After passing the test, install it back to its original position. For o...
