Design Of Human-computer Interface Function Of Computer Interlocking Teaching System Based On VC++ Technology

The computer interlocking system of railway signaling is a safety-critical system that controls wayside signal equipment and ensures the safety and efficiency of train operation in railway station.How to use and master computer interlocking correctly is an important teaching content for students major in railway signaling and railway transportation.However,the high cost of computer interlocking makes it difficult to meet the teaching need of school practical training,so computer interlocking teaching stays at theoretical level in most schools and students can’t have actual practical training.Therefore,it is urgent to develop a human-machine interface function of computer interlocking teaching system so that students can operate computer interlocking and know the handling of failure conditions in computer interlocking system.By analyzing the structure and function of computer interlocking system,the module function and design scheme of human-machine interface function of computer interlocking simulation teaching system are proposed based on the layout of station signal plan.And it is developed in Microsoft Visual Studio 2010.The specific research contents are as follows:(1)First,the module structure and function of the simulation teaching system are elicited after analyzing structure and function of computer interlocking system,and then each function module is designed in detail.(2)Second,all functions of the simulation teaching system,including man-machine interface display,operation processing and communication between man-machine interface are realized with Visual C++ in Microsoft Visual Studio 2010.(3)Next,in order to realize the teaching function of the simulation teaching system,fault setting function for signal,switch and track circuit and train running simulation function are added.(4)Finally,when the development of the systems is completed,a large number of test have been done to verify and improve functions of the simulation teaching system.
