Analysis of District Handover Procedure of High-Speed Maglev Operation Control System

The district handover is one of the key technologies in the high-speed maglev operation control system. It completes the transfer of safety responsibilities when a train passes across two districts, and it directly affects the safety and stability regarding train operation. This article first makes a general analysis of its mechanism, including the essential characteristics, stakeholders and tasks of the district handover. In order to simplify the complexity of the behavior models, the whole procedure is divided into four phases, namely, the preparation phase, the stopping point stepping phase, the vehicle reception phase and the termination phase. The information interaction and timing relationship of these models are presented by UML.
