Study And Design On The Simulation System For Tactical Training Of Armored Units

With the continuous advancement and development of computer technology,operation equipments are renewed and replaced quickly,the military training methods of armored forces are changing,and more and more virtual simulation trainings replace the traditional trainings step by step.Simulation of military training is used for the skills training of equipments operation,exercise training of the staff and analysts,and command training of perception of the battlefield situation of commanders.The main components of military training include physical training,psychological training,professional training,tactical training,and many other elements.As a technical arm,the armored forces units' simulation training contents are to model and quantitative describe some environments,such as geographical environment,atmospheric environment,marine environment,electromagnetic environment and other special environments,and to construct the background of battlefield environment fulfill the training requirements.We can finish basic skill trainings,such as driving,communication and shooting.By using simulation equipments,we can achieve the tactical training programs of single tank,platoon,company,and battalion gradually.The form of war has changed dramatically since 1980.We find the increasing technological contents of equipments from the Gulf War and the Kosovo War.The information condition and integrative joint operations demand all-around qualities of fighters highly.Tactical training of armored forces is limited by time,space,political situation,security,weather and many other factors.Skilled operators' skills are the basis of combat effectiveness,only when the crew have a close coordination,commander has a right decision-making quickly,and the various components of combat units have a perfect harmony,will we destroy the enemy and preserve ourselves effectively.If a gunner wants to take a good grade,he must operate cannon more thanⅩhours every year.The overhaul period of cannon is aboutⅩhours,and in addition,cannon system consume vast power, when we operate cannon.We operate tanks at first,one hour tank's working costing more thanⅩYuan per hour.In order to avoid the blind area of the laser finder,training objectives must be located beyondⅩmeters,so that the units often have no chance of training because of these limited conditions.Virtual reality(VR) is an applied technique of computer,which emerged in 1960's and developed quickly in 1990's.VR is a wide involving and complex technique that including computer graphics,interface of human and computer,interactivity of human and computer, artificial intelligence,psychology,3-dimensional sound,and many subjects and techniques. VR has three main features:immersion,interaction and imagination.Immersion means the real degree which user feels when he exists in virtual environment.Interaction means the degree which user operates objects in virtual environment,and the degree which callback from virtual environment(including real time feature).Imagination means that VR is not only a medium,a senior user interface,but also reflects ideology of designer.Just because of the features of VR,it has widely applied in military science,medical science,education, culture,art and many fields.Tactical simulation training has many advantages of shortening the training cycle,saving training costs,operating safely,processing transparently,and avoiding influence of weather conditions and site constraints,etc.It has been attached by the military of many countries.For instance:A tank driver will gain more driving experience in one hour by simulator than 6 months by a real tank in 6 months.As a superpower,the United Status's military simulation technology is always going to the forefront of the world.In 1983,"Defense Advanced Research Projects Agency" made out the "Analog Network(SIMNET)" program.Cooperating with the U.S.army,they want to develop the technology which can connect all single simulators by one net.The concentrate central tactical trainer(CCTT) has put tanks and flight training simulator in one net, connecting hundreds of simulators eventually,and implementing distributed collaborative training including armored forces and other arms.The development of military training simulation is unenlightened in our country,so that the relevant technology is still underdeveloped,and distributed combat simulation is still in the research phase.This technology has obvious advantage.It is the main direction to develop for the simulated training system.Under the situation that the research of virtual reality is just begin in domestic,this subject established the foundation for promoting the further research and application of the virtual reality technology and training simulator technology in the virtual training field.Based on the methodology and theory of armored tactical training above,according to the armored military training program,combination military education,training bases,and military training of the actual situation.The essay has a comprehensive summary of the armored units' training content.In order to have a single function,we must divide the training contents reasonably,model analysis at first,implement the software,assemble it with real equipments or semi-real equipments,at last,a new armored tactical training system will be assembled step-by-step.It synthesizes professional technical training, tactical training,and the current training of troops,To satisfy the armored units' requirements of tactical training,this paper carried out a new framework design.The focus of this study is the analysis of the cannon contrd system's structure and function further.This paper refine the support components of the system and the structure,modularize mission needs,analyze the 13 main function modules of the system and relations between these modules,and describes function modules one by one.This paper supports the mobile system's mathematical model of simulation,giver the example of flow chart which is operated by battalion commander.The focus on tank cannon control system,in accordance with the operation flow,includes:tank searching,tracking, distinguishing,judging,choosing the battlefield goal,the analysis of tanks shooting error, laser ranging,environmental data collection,cannon simulation of single tank,and assessing the battlefield situation with the participation of armored units.In the process of research and development,I use VisualC++6.0 as the development platform mainly.And I also use the General MapGIS,MultigenCreator,Vega,OpenGVS. Matlab and other software.I combine the ability of armored tactical training,system monitoring capabilities,as well as the simulation training content of driving,shooting, command(communication),and verify the feasibility of a person's professional skills in-the-loop simulation training.Because of the limitations of time and condition,the visual simulation system of tank driving and training simulator exists a lot insufficiencies,such as operate sense of reality is not strong,environment of battle field is monotonous in the system,virtual instrument is not precise enough,these contents will be proposed to be perfect in the work afterward.After studying the content of single tank tactical training and armored units tactical training,I dare say,a single tank can observe battlefield,search,find, and cannon at the target.In the red army tank company attacks blue chariot platoon,the system supports two-dimensional map operations in the preparation phase of cannon fighting.In the implementation phase,it can do much tactical action training,such as marching,dispersing,spreading,impinging,etc.All of these preliminary validate the system which has the advantages of feasibility,practicability,and vitality.
