The Design And Implementation Of Client-Side For A Simulation Training System Of Army's Equipments

With the accelerated process of national defense modernization in China,the shortcomings of traditional military training are more and more obvious,such as the traditional military training lasts long,the consumption is large and the risk is high.The virtual simulation technology can solve the problem of traditional military training by its unique advantages,such as repeatability,short cycle,low risk,no damage,controllability and so on.Simulation training system's client-side is a client software which is based on virtual simulation technology,and supports army equipments simulation training.The simulation training system's client-side is designed and implemented by the software engineering method.After a detailed analysis of the daily training tasks of the army equipments,the functional and non-functional requirements of the system are clarified,and the function modules are divided.Client system implementation includes two parts: model making and visual simulation.Using MultiGen Creator as a model builder to create weaponry models,battlefield terrain,and other scene element models;Using VTree engine as the basic platform for visual simulation to complete the battlefield 3D visual simulation;In addition,the client in the same local area network usewindows socket communication technology to share data in different seat equipments,the sharing data includes the equipment position and attitude data,the location of the blast point,artillery trajectory,battlefield terrain,target unit data,weather data and so on,and the clients obtains the data from the 3D scene and uses the serial communication technology to complete the data transmission between clients and the specific hardware systems.The simulation training system's client-side supports the daily training of eleven kinds of equipments,such as a certain type of reconnaissance vehicle,a certain type of battalion command vehicle,a certain type of artillery,a certain type of reconnaissance and calibration radar,a certain type of unmanned aerial vehicle and so on.The participants use the client simulation training system can quickly and efficiently improve the equipment operation skill and the cooperation of different equipments in combat.
