摘要
A system to monitor the operational state of a coal mine drainage system is presented, fault problems are diagnosed and solved. The system includes a Single Chip Microprocessor (SCM) Atmega169 and an industrial PC used as a master-slave structure. Characteristic parameters of the drainage system were extracted and analysed. As well, a research project on the fault diagnosis of centrifugal water pump based on a fuzzy synthetic evaluation method is initiated. The proposed monitoring and fault diagnostic system can improve the automation, safety, reliability, economy and efficiency of mine drainage systems considerably, decrease blindness and shorten the time required for water pump maintenance.
