The Design And Implementation Of Server-side For A Simulation Training System Of Army's Equipments

The traditional military theory teaching is usually tedious,the teaching results is less effective.Military exercises allow soldiers to personally operate equipments,and bring instant feedback to them.Thus,it makes teaching effect better.However,this approach faces the facts that military exercies are not easy to carry out,and resourse-intensive.With the technology of virtual simulation becoming increasingly mature,simulation training used as an emerging method of military teaching becomes a reality and is an effective and easy to carry out.The simulation training system of army's equipments provides one college with a simulation training teaching method.It allows cadets to manipulate equipments and provides features of synchronizing scenery-view and establishing communication between virtual equipments and military hardware devices.From functional perspective,the system can be devided into client-side and server-side.The server-side was implemented with C++ Language,technologies of TCP network communication as well as VTree simulation engine.The server-side primarily includes: function of stable network communication service,function of scene simulation with stable render performance and function of global configuration storage.According to the software engineering methods,the functional and performance requirements are firstly analyzied,the process of designing system is executed and the system architecture of the server-side is put forward.Then,According to function,the server-side is devided into 6 modules,including network communication,scene simulation,walkthrouhgh,picking entity,configuration management and message handling,and then the detailed designeing process of modues is executed.According to the function requirements of network communication and message handling,the system network communication protocol is designed with reference to HTTP protocol.At the same time,the network message data structure is designed,and then a configuration data structure is designed according to the configuration managerment requirement.The system is now deployed in a college,all functions mentioned in functional requirements are performs correctly,and performance satisfies exceptions.
