Abstract: In order to ensure the normal operation of the mine hoist and to ensure the fault diagnosis timely, accurately and reliably, the fault diagnosis solution of t he hoist system based on the remote monitoring and control was provided.The system was designed with a SIMATIC WinCC configuration software of the windows cont rol center, Visual BASIC6.0, SQL Server2000 and Office Excel.With the fault diagnosis expert system of the mine hoist, the remote monitoring and control and the fault diagnosis was conducted.A independent fault diagnosis system of the mine hoist was integrated in the mine digital information network to form a general coordinated op eration mechanism. Thus a remote on-line diagnosis function could be realized and the requirements of the rapid fault diagnosis, maintenance and others could be met.
