Industrial mining equipment monitoring PCBAs integrate data acquisition, signal processing, communication transmission, and fault alarm functions. They are primarily used for real-time monitoring of mining equipment's operating status to prevent production stoppages or safety incidents caused by equipment failures. Typical application scenarios include:

　　Underground mining equipment: Monitoring temperature (bearings, motors), vibration, oil pressure, and current for shearers, roadheaders, and face conveyors;

　　Hoisting and transportation equipment: Monitoring speed, brake oil pressure, and wire rope tension for mine hoists;

　　Mineral processing equipment: Monitoring bearing temperature, vibration frequency, and material level for crushers and ball mills;

　　Auxiliary equipment: Monitoring motor current, air pressure, and flow for fans and water pumps.
