Title:
SYSTEM AND METHOD FOR DIAGNOSING FAILURE OF BELT-TYPE CONVEYOR
Document Type and Number:
WIPO Patent Application WO/2017/197873
Kind Code:
A1
Abstract:
Provided are a system and method for diagnosing a failure of a belt-type conveyor; said system comprises a current sensor, an oil-pressure sensor, four rotational-speed sensors, a PLC, and a master computer; the current sensor is mounted on the drive motor of the belt-type conveyor; the oil-pressure sensor is mounted on the hydraulic cylinder of a tensioning apparatus; the first rotational-speed sensor is mounted on the drive motor of the belt-type conveyor; the second rotational-speed sensor is mounted on a driven drum of the belt-type conveyor; the third rotational-speed sensor is mounted beneath the belt, 10 m away from the machine tail; the fourth rotational-speed sensor is mounted beneath the belt, 10 m away from the machine head; the PLC, as the slave computer, receives a sensor signal and transmits the signal to the master computer; the master computer processes the signal in real time to enable status monitoring and failure diagnosis of the belt-type conveyor. The method utilizes sensor redundancy information and constructs a parsing model of the conveyor to observe its status and diagnose failures; thus failures are discovered at an early stage, enabling the healthy management of a device.
