Safety Indez of High-Speed Maglev Train Decentralized Operation Control System
The decentralized operation control system, which realizes the function of operation command and safety protect ion to high-speed maglev train, is a kind of safetycritical computer control system. On the basis of the experience of developing, debugging and running the decentralized operatio n control system engineering prototype, using for 1.5km high speed maglev experimental railway line, two safety indexes that are used to quantify the security of the decentralized operation control system were proposed-stable safety probabil ity, mean time to insecure failure, and a 3-state Markov safety critical system model was set up. Based on the model, quantita tive analysis was made to the two safety indexes of the decentralized operation control system which consists of a sing le functional unit. At last the expressions of the two safety indexes, which are used to obtain the stable safety probability and mean time to insecure failure of the triple module redund ant decentralized operation control system, were got.
