Research And Implementation Of Signal Simulation And Operation Training System

With the development of the urban rail transit industry,the metro transportation companies crying out for the technology talent with both abilities of transit operation and production management.The subway industry faced a new trend of construct ion boom,and gradually been a main transportation tool in daily life.At present,only a few domestic companies have the ability to train talents.Therefore,the market for training services in the industry has a broad prospect in the coming ten years.Fo r the operation headquarters which put train service-skilled talents as one of its important training management operations,one of the key cores-training resource support is particularly important and depend whether they can promote related training effectively and scientifically or not.With the help of training equipment resources,it can play a greater role in the standard operations of the station operations,dispatch,and signal professionals under the conventional line operation,as well as the emergency skill response under line signal failure.The existing professional training mainly depend on the mainline operating equipment.Since the operating equipment is responsible for the mainline operational tasks,employees actually have very less opportunities to operate the equipment during the training,and the training courses also have a negative effect on the operating equipment.This paper studied the railway station signal control system and developed a signal simulation operation training system which is consistent with the actual station operation.The following summarizations were the main research works of this paper:Firstly,introduced the background and research meaning of this paper.Analyzed the contents of the research and each chapter in detail based on the latest domestic and abroad studies on the station signal simulation and operation training system.Then,expounded the concept and theory of the station signal control system and the main technical methods,and the structure of the station signal control system was introduced.The technical foundation for developing system was described in detail.Did the Summarization works from the aspects of facts and features used in various technologies,which provides theoretical support for the design and implementation of the system.In order to fit user needs,analyzed the functional requirement of the signal simulation operation training system,including the display and refresh function of the battlefield diagram graphics,human-computer interaction function,interlock function,and signal device status simulation function,which makes the system design closer to the true station.And on this basis clearly defined the design ideas of the system and determined the simulation system architecture.The C/S three-tier structure model is used for system design,and the main functional components of the system were modularly divided.Then,the design works of the system including battlefield diagram interface,station interlock table,simulation of the access control process,etc.and the route search algorithm were studied in detail.Finally,the system software were developed by using C# programming language and object-oriented technology.The simulation works of each modules on the station signal simulation operation training system were realized based on Visual Studio 2010 software development platform and SQL Server database.The simulation results reveal that the system of this paper satisfied the system functional requirements of the operation headquarters of the Guangzhou Metro Corporation.It can not only provide a real operating environment for the trainees,but also check the theoretical basis of the trainees.It can also simulate the simulation of train route selection and save the labor an d materials for the company.
