Abstract

A type of computer-interlocking control system of 2 out of 2 multiplying 2 was provided based on the combination of fault-switch and fault-shield techniques. A set of redundancy scheme was designed according to system hardware and software and then the status-transformed model of system was established in combination with the practiced application experiences. Based on this model, the reliability and security of maintainable system were studied with Markov procession. In addition, the influences of faulty-covering rate and maintainable rate on the reliability and security of the system were analyzed. Simulation results show that the system has excellent property of reliability and security.
