摘　　要：为降低投资成本并有效保障列车运行安全,提出一种在进路首未两端设置计轴点的列车进路占用检查模式,设计并实现了一种进路状态判别处理器。基于RSSP-I协议实现进路状态判别处理器与联锁系统之间的通信,进路状态判别处理器接收联锁系统发送的进路选择信息和道岔状态,并进行一致性校核,保障进路占用或空闲状态输出的正确性。To reduce the cost and ensure the safety of train operation effectively, a new mode of train route occupancy check by setting up axle counting at the starting point and ending point of a route is proposed and a route status identification processor is designed and implemented. The communicate of the processor with the interlocking system is realized based on the RSSP-I protocol. The processor can receives the data of route selection and switch status from the interlocking system and check the consistency of route selection and switch status, thus ensuring the correctness of outputting the status of route occupied or cleared.
