The B-PHM system comprehensively collects monitoring parameters, electrical parameters, environmental data, status parameters, video data, factory documentation, and maintenance records from key locations of power supply equipment through online monitoring, system integration, and manual data entry. The system utilizes artificial intelligence algorithms, performs data cleansing on the equipment status parameters, and trains intelligent prediction models. Simultaneously, it forecasts trends for related temperature and vibration data, automatically recognizes video data, and conducts in-depth analysis. By applying intelligent models, the system enables online monitoring of critical components, status assessment, and lifespan prediction for equipment, while also providing tailored maintenance and repair strategies for each device.
