Abstract :
In order to meet the requirements for high security and high availability of critical control system in many fields of modern industry, a new system architecture - TVSDC is proposed in this paper and the subsystems are designed. On this basis, Markov model for TVSDC is established. A comparison of TVSDC with other various existing control systems from four indexes which are reliability, availability, maintainability and safety is studied. The results show that the reliability of the TVSDC is the best, meanwhile, availability and safety of this system is also very excellent.
