Temporary speed restriction is a core function of the train control system for high speed railways.The missing or wrong issuance of Temporary Speed Restriction(TSR)commands may cause great safety hazards.This is especially true for complex lines,where TSR commands may not be issued correctly because the relevant personnel are not familiar with the line information of civil works and signal systems,and the speed restriction rehearsal is dependent on the real operating environment,which affects both operational efficiency and safety.To solve these problems,this paper studies the automatic generation method of TSR parameters based on the speed restriction parameters of the civil works as well as the integrated simulation technology of train control equipment.On this basis,it describes the design and implementation of a TSR decision support system.The proposed system can automatically generate the TSR parameters of the signal system,and provide an independent simulated rehearsal environment.The trial operation results of system deployment show that the proposed system can effectively assist the relevant personnel in efficiently and accurately completing the TSR related operations.
