| Abstract: | According to mine hoist and its high reliability requirement for control system, using fault tolerant theory and techniques, a three module redundancy comparison fault tolerant system structure is proposed which consist of PLC.The fault tolerant system has been applied into full digital control system for mine hoist, and as the operation and protection unit which executes key tasks. Its powerful fault tolerant and high reliability have been proved by practice. |
