1.  Programme overview

Based on Unity3D equipment support simulation scheme and VT-MÄk distributed simulation tool, a joint operation simulation experiment environment is constructed to provide precise support requirements Based on Unity 3D, a highly immersive, interactive and deeply inspiring human-computer interactive maintenance support site is constructed. Users can make use of customized tool library tools through interactive peripherals, such as mouse, 3d mouse, data glove, etc. , to realize the effective interactive control with the 3D model of VR virtual equipment components, complete the whole process of equipment support and maintenance, and the system automatically records the maintenance and training process, and according to the standard support flow and evaluation standard, the system realizes the technical evaluation of the whole process of maintenance and the management of the trainees’training files, and satisfies the three-level training requirements and the actual maintenance support requirements of the base-level relay Foshan base.

 
2.  Introduction of the scheme
 2.1. System composition

 2.2. Module introduction
2.2.1. Virtual maintenance training universal platform
⑴Efficient universal open bottom model system

       Virtual maintenance training content aggregation model, training-oriented virtual prototype model, virtual maintenance training process model, virtual maintenance training evaluation model and other four models:

⑵It is easy to understand the equipment principle in a visual way, support the 3D model of the component extension, integrate and interact with the component schematic diagram and digital instrument, and finish the operation and maintenance in an interactive way, to grasp the operating rules and essentials is easy to visualize the understanding of equipment, extension principle and structure

                                                                
                                                        Initial effect of device model                                                     Device model expansion effect

⑶A variety of training patterns

2.2.2. VR-Link for Unity U3d interface
       VR-Link for Unity is a customized VT mäk communication middleware for the Unity game engine that supports Hla/dis applications and is a customized version of VR-Link.

      VR-Link for Unity includes a send and receive class middleware for Unity 3D, which allows Unity 3D to evolve from a pure game scenario to a simulation class that is compatible with HLA1.3, Hla 1516, HLA-evolved, and DIS protocols. VR-Link for Unity, as a component of the Unity toolset, provides a c #-encapsulated interface library for developers to easily publish Unity entity mapping, articulated motion, weapon fire, explosion, etc. to the overall simulation network.

2.2.3.Simulation experiment environment of Equipment Support Command training
1、The members of the combat unit shall be the objects of support and report battle losses, ammunition consumption and ammunition requirements to their superiors;

2、人在回路控制（指挥结构），接收作战单位信息,向装备保障组下达保障命令，仿真过程中，变更保障难度；

3、Support Subject Development Release Group, according to the needs of support, simulation model and subject development, and release;

4、Guide and Control Evaluation Group, training subjects selection, simulation data storage and playback disk, battlefield situation display, evaluation;

5、Equipment Maintenance and support group, receive equipment support orders, implement equipment battlefield repair and bad to receive, report equipment requirements;

6、The equipment supply support group receives the Equipment Supply Order, implements the supply support, records the material, the transport vehicle information to issue the active warning information; Vehicle information includes vehicle number, model number, volume, load, vehicle status, running route and so on.

 
2.2.4.Based on Unity3D virtual teaching, training, examination, support function
       Generate force, input battle plan, Equipment Support Plan and implementation plan according to the desired requirements, generate support simulation battle based on Unity3D, provide initial situation and action plan of operation and equipment support, according to the progress of the battle, the consumption and the information of the equipment battle damage are transmitted to the equipment support simulation platform in real time, according to the corresponding support requirements, support plan and its operation rules, the equipment support organizations carry out the supply, equipment supply and war damage equipment assessment and repair. 

3. Technical characteristics

1.     This paper constructs an immersive equipment maintenance training environment, and combines it with virtual and real simulation experimental environment to realize the effective interaction between virtual maintenance and simulation experimental environment, and based on system equipment wartime support peacetime maintenance training

2.     Through a variety of equipment support maintenance training methods, it effectively meets the three-level training requirements of the basic-level relay base, providing immersive and high fidelity equipment —— Human Interactive maintenance support scene, effectively enhance the training effect of equipment support maintenance.

4. Application scenario
       Based on the Unity 3D equipment support simulation scheme, it can be used in virtual teaching, virtual training, virtual examination, virtual support command, support scientific research, etc. , to meet the on-the-spot or long-distance learning needs of the teachers, students and army personnel in the teaching of equipment maintenance, to facilitate the students to master the operation and use of equipment, the key technologies, and to upgrade the proficiency level of core skills, maintenance skills and methods, it can carry out equipment grading ability test, evaluate the tester’s performance or ability, support real-time dynamic or virtual battle scene’s fault alarm and maintenance order, maintenance resource dispatch, organize and implement site or base maintenance, support the scientific research and service of the troops by the personnel of the Scientific Research Section, and meet the requirements of the troops for the new equipment support resources and technical support through the remote network.
