3. System function
3.1 Co-training function
The trainees use virtual operation tools to simulate the disassembly operation process of the equipment in the real environment, and make strict safety judgments in accordance with the real operation steps. The decomposed device model is so small that it can reach the fine level of a screw. Through the signal collection of the curvature of the finger, it can track the movement state data of the hand and realize accurate positioning. The CMTS allows multiple virtual seats to work together to realize the parallel and antegrade disassembly and assembly of virtual equipment according to a certain process, so as to realize the purpose of collaborative training. 

3.2 Comprehensive guarantee function
Equipment support function, realize virtual maintenance of damaged equipment; material support function, realize delivery and supply of needed items, etc.; troubleshooting function, realize check equipment integrity and troubleshoot problems; connect with ILS system platform data to realize integration Simulation of the maintenance support link in the support process.

3.3 Equipment teaching function
CMTS can realize the learning of the function, structure and principle of the equipment and the cognition of the spatial location, and handle the operation process, emergencies and other situations. The teaching function mainly includes three modules, namely: principle module, training module, and assessment module. The principle module includes multimedia information such as teaching pictures, 3D animation, audio, text description, etc. The trainees can learn according to the way of watching pictures, learning text content, watching 3D animation and listening to audio, and can explore and learn according to the prompt information; training module According to the highlighted or flashing display of the model, the effect of 3D animation and text description are adopted to realize the training module, so that the trainee can achieve the purpose of learning; the assessment module, the trainee can use tools according to the specific purpose to complete specific functions, Realize the assessment mechanism according to the operation results.

5. Product advantages
1) The system supports multi-platform customization
CMTS supports stand-alone maintenance training, multi-person collaborative maintenance training, wearable maintenance training and mobile version maintenance training. Multi-version mode applications supporting mobile version, PC version and Web version. 

Mobile version:
Support multi-person collaborative disassembly and assembly, with basic information display function, suitable for theoretical knowledge learning.

PC version:
Using hardware such as motion capture and Oculus, it has good real-time collaboration capabilities, so that users can feel the immersive effect.

Web version:
The web version supports the interactive operation of the mouse and keyboard.

2) Multiplayer VR immersion
CMTS is equipped with multi-client cooperative disassembly and assembly equipment functions. Operators in each seat can realize multi-person immersive collaborative interaction according to the configured virtual helmets, motion capture, and Wii controllers, and realize the function of multiple people training the same subject together through the configured standardized operation process, operation tool library, etc.

3) Scalability
Control extension:
CMTS adopts object-oriented thinking, which can realize the development of customized controls for different needs.

Function expansion:
According to the new demand function, realize the new user control, thus insert the simulation system, make the software and the module independent management. Three-dimensional scene expansion: This software can customize the scene and realize the function of customizing the scene. Application field expansion: According to the needs of users, customize the system of its application fields, such as aerospace, virtual real estate, education industry, etc.

4) AR augmented reality
CMTS is equipped with augmented reality modules, including tag card recognition, 3D object recognition and facial recognition. This module supports the function of self-defining logo pictures. The system enhances the corresponding models and effects according to the pictures configured by the user, so as to realize a series of operations such as disassembly and assembly of the virtual model.

6. Application areas
military training:
Through multi-person full-body motion capture equipment and virtual helmets, it can provide soldiers with absolutely safe "thrilling" scenes and realize the training of the original "impossible" missions. Improve the practice of multi-arm combat skills and training of attacking skills.

Military education:
Through the process modeling of the training teaching environment, the operation and skill training of the officers and soldiers in the military field can be realized; the trainees can feel the fidelity of training and the flexibility of training.

Equipment support:
For equipment maintenance support, through virtual modeling and virtual disassembly, virtual simulation technology can be used to evaluate the familiarity and skill training level of maintenance personnel with weapons and equipment.

Weapon development:
In the weapon development stage, by viewing the design model from the first perspective in the virtual environment, it is more conducive for the designer to observe the rationality of the combination of parts, so as to adjust the design plan. At the same time, multi-person collaborative design can more effectively complete the weapon design. Task.

7. Successful cases
China Star uses the CMTS framework to develop the "cooperative maintenance training simulation software" for a military institute to achieve the purpose of multi-person equipment support maintenance, teaching and training, and to provide a virtual immersive experience for the institute’s business skills training. It provides an effective way to assess the familiarity and skill training of maintenance personnel for weapons and equipment.
