Abstract

As a crucial component of railway transportation, the safety protection measures for local railway shunting are inadequate. The design of a shunting protection system that fulfills the requirements of the local railways is essential in guaranteeing safety during shunting operations and also enhancing efficiency in shunting operations. The vehicle-ground radio communication serves as a key link in shunting safety protection, which is closely related to the safety and efficiency of train operation. In this paper, the Systems Modeling Language (SysML) is used to analyze the process of vehicle-ground radio communication. We propose the activity diagram probabilistic model description method based on discrete-time Markov chains to convert the SysML activity diagram into the probabilistic model, which can provide a reference for the formal verification and analysis of the SysML model and reduces the difficulty of directly using formal methods. We analyze the reliability of vehicle-ground wireless communication under random conditions. And the system's control capability is further enhanced through the optimization of vehicle-ground wireless communication transmission strategy. The results hold significant reference significance to the improvement of shunting efficiency and the design of shunting protection system.
