Research and prospective technology on optimization schemes for new generation signal systems
As urban rail transit gradually moves towards networked operation,the traditional signal system is facing the urgent challenges of compatibility and scalability due to the complex system architecture and redundant interfaces.This situation not only restricts the flexibility of urban rail transit capacity deployment,but also puts forward higher requirements on the intelligence level and safety reliability of trains.To strengthen the train's ability to perceive the information of the traveling space and in-vehicle environment,and to improve the utilization rate of trackside equipment,the fully automatic train operation system,which is based on the principle of fault-safety operation and integrates automatic and autonomous train operation,is the development direction of the new generation of signal system.In line with the basic architecture of TACS system and its system principles,this article focuses on the deep integration between vehicle and signal system to streamline the system architecture and optimize the information flow path,and elaborates the system and equipment configuration optimization scheme based on the capacity demand,decouples the on-board control and the trackside control,and improves the compatibility and ease of deployment of TACS system;finally,this article explores the direction of cutting-edge technology implementation and conducts technical analysis on the degradation backup mode of TACS system based on autonomous perception to ensure more effective utilization of limited line and vehicle resources under the premise of operation safety,so as to give full play to the advantages of TACS system in terms of downsizing and increasing efficiency.
