Research And Implementation Of Multi-stations Cooperative Training System Based On MAS For High-speed Railway

With the rapid development of Chinese high-speed railway,new technologies and equipment,such as Computer-based Interlocking(CBI),Centralized Traffic Control(CTC),Chinese Train Control System(CTCS),bring an efficient transport organization model,but also put forward higher requirements on front-line operators of the professional quality,operational skills and emergency response capacity.In view of the circumstance that the field equipment could not be directly used for training,this thesis applies the Multi-agent System(MAS)to the railway station simulation system for the purpose of realizing the training of high-speed railway operation personnel.On the basis of ensuring the user interface,operation mode and interlocking relationship with the actual system,it aims to achieve multi-station coordination,multi-control mode and multi-simulation scenarios under the practical training.The main works of the thesis are as follows:(1)Introduce the main theory,system architecture and main function of CBI and CTC system for the main operation object of high-speed railway operation personnel.The MAS theory is analyzed and the applicability of MAS in simulation system is demonstrated,which provides the theoretical basis for the follow-up study.(2)Based on the analysis of the functional requirements of the system,the centralized MAS structure of the three software agents including interlocking,station terminal and teacher machine is designed,and the module structure of each agent is designed in detail.It makes a description on the knowledge base,control functions and workflow of the agents,to achieve the communication and collaboration among agents.(3)Detailed design of the basic functions of the agent units:design of the station graph elements to achieve agent man-machine interaction module display function;realization of the station basic,flexible,guide route based on the shortest path algorithm;design of basic interlocking function and train operation simulation function according to equipment interlocking relationship.(4)Design and implement CTC self-discipline control function.This part studies the process of shunting operation of CTC station,and uses the track circuit segment as the object of collision judgment,and constructs the optimization model of CTC station shunting operation plan according to the characteristics of long and short route.By solving the small scale example,the correctness and feasibility of the model are verified.This modeling idea even can be used into the process of CTC shunting route self-discipline control.(5)Case study.Based on the actual station structure,build the Beijing-Shanghai high-speed railway simulation training platform,and design training assessment outline,to achieve 23 stations under the coordinated operation of the vehicle operation simulation.
