Design And Develop Of The Virtual Train Group For The Metro OCC Traffic Dispatcher Simulation Training System

With the rapid development of the railway,more and more railway dispatchers are needed.Because of too much expense and low efficiency the traditional way of training railway dispathers hasn’t already met the requirement. So that a kind of new training way that using computer simulation technology to train railway dispathers emerges,which is low expense and high efficiency.And OCC traffic dispatcher simulation training system is an important part of the OCC dispatcher simulation training system.It will provide strong support for the railway traffic dispatcher training.Simulating the operation of train flow on line (virtual train group) is the core content of the OCC traffic dispatcher simulation.It provides all the train simulation model for the entire rail transit comprehensive simulation training system.Every train establishes the operation model on the basis of traction calculation theory.The train is drived by virtual driver,and constrainted by signal system and train diagram.Nowdays,the research of train group at home is mainly to aim at the shop painting and adjustment of the train diagram, and the line condition, train properties and characteristics of signal system treatment are quite simple.Therefore, in this paper,the design and development of virtual train group has very important practical significance.Combined to the function of the metro OCC dispatching simulation training system the virtual train group is designed and developed on the basis of the realization of the function of the virtual train group.This paper first introduces the function and composition of the simulation training system and the basic environment related train operation.Then,combined to the characteristic of train operation,virtual train group has been made detailed functional requirement analysis.Then,the modules are designed and implemented,including the design and implement of data structure for virtual driver,the modeling and implementation of train operation,the modeling and implementation of ATP,the design and implemention for train group control management function.Finally,the virtual train group is applied to the simulation training system.Combined with the function of the simulation training system,the function are tested and verificated.And from two concrete cases,this paper expounds the impletement of the simulation of train group and the function for training dispatchers.The simulation results show that the train group module is applied to the simulation training system,not only can provide the dispatcher a real operation environment,but also can verify the ability of the line through,and can simulate various abnormal driving,realize the dispatcher training function.
