This paper addresses the existing problems of the 64D relay-based semi-automatic blocking/automatic inter-station blocking system,which is widely used in China's single-track railways,such as low transmission reliability,poor maintainability,poor scalability,difficulty in intelligent fault diagnosis,and difficulty in fault locating.It studies and designs a computer-based inter-station blocking system based on vital computer technology,secure communication technology,and electromagnetic wheel detection technology.The proposed system provides the integrated functions of inter-station blocking,secure information transmission,and section occupancy detection.The blocking logic circuit is implemented through the software-based approach,the redundant design is adopted to improve reliability,and the proposed system is compatible with both the existing relay interface of interlocking system and the extended communication interface.The practical application shows that the proposed system can simplify the equipment composition,reduce the engineering costs,improve the fault locating efficiency,and meet the safety and development needs of railway signaling systems.
