[0002] With the development of my country's social economy, the number of private cars, official cars, commercial vehicles and trucks is increasing, and the vehicle rescue service industry that develops along with it is also changing with each passing day.

[0003] As an important force to ensure the safe and efficient operation of highways, vehicle rescue faces extremely high safety risks during operations. In the past, operator training was mostly done through offline theoretical knowledge learning and practical training before going on the road to work, which made it difficult to prevent safety risks. The existing training system and training methods are costly (the rescue company needs to provide enough parts for operators to practice); in addition, the training content for operators is relatively large, and the existing training system and training methods are inefficient, which greatly prolongs the training cycle. Summary of the invention

[0004] In order to solve the existing technical problems, the present invention provides a vehicle rescue VR training system;

[0005] It includes a server, in which a vehicle rescue VR training system and a login system for trainees to enter the vehicle rescue VR training system for training are installed;

[0006] It also includes a VR helmet and a VR operating handle, wherein the VR helmet is connected to the VR operating handle;

[0007] The server is used to receive an operation menu interface from a trainee wearing a VR helmet manipulating a VR operating handle after starting the vehicle rescue VR training system. The vehicle rescue VR training system determines the training content to be conducted in the menu interface according to the operation control signal output by the received VR operating handle.

[0008] A further solution is that the vehicle rescue VR training system includes a trailer model selection module;

[0009] The trailer model selection module includes:

[0010] Flatbed recovery vehicle training module to simulate clearing a broken down or accident vehicle from the road.
