| Summary: | Railway transit vital computer is the core equipment to ensure the safe and reliable operation of train. The common architecture of vital computer on rail transit was described, and the key reliability indexes by reliability analysis was calculated. An improved vital computer architecture was proposed based on the common redundant architecture in this paper. By contrast with currently commonly used architecture, the improved architectures can significantly improve system reliability, and can be widely used in railway system or product which demanding high traffic safety and reliability. The reliability analysis method and results described in this paper can be referred by other vital computer reliability analysis. |
