Abstract: To address the problems of strong manual dependence, significant subjective influence in traditional train operation control, and the inability to automatically identify ground interlocking information, this paper developed a train route pre-announcement system based on the real-time status of interlocking signal equipment. It adopted a distributed architecture to deploy the interlocking information acquisition subsystem, and obtained real-time status information such as signals, turnouts and track circuits from the station computer interlocking system through one-way serial communication technology, realizing the dynamic establishment and static verification of station routes. It relied on LTE-R wireless communication technology to realize train-ground information interaction and transmitted the matched route pre-announcement information to on-board equipment. Practical application verification shows that the system can automatically perceive the route ahead of the train, reduce the labor intensity of locomotive drivers, improve the intelligence level of train operation control, and provide technical support for the integration of future train operation control and dynamic dispatching.
