| Abstract: | In order to improve the efficiency of the interlocking system, an execution-supervision computer system is developed. Compared with homogeneous and heterogeneous 2 vote 2 system,the novel system improves the reliability by reducing software complexity while keeping the system function. The simulation and comparison resultsshow that the complexity of execution-supervision software is the lowest,only 0. 550,which proves the validity of the execution-supervision structure. |
