Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1-2 As shown, the present invention provides a safety training system based on virtual reality, including a VR output device 1, a VR input device 2, a VR position tracker device 3, a somatosensory device 4 and a management platform 5;

[0027] The VR input device 2 is connected to the VR output device 1. The VR output device 1, the VR position tracker device 3, and the somatosensory device 4 are all connected to the management platform 5. The VR output device 1 and the VR input device 2 are respectively provided with a plurality of tracking sensors. The VR position tracker device 3 detects the position of the tracking sensors and transmits the position to the management platform 5 to realize the positioning of the VR output device 1 and the VR input device 2.

[0028] The management platform 5 includes a 3D model library management sub-platform 51, a visual editing sub-platform 52, and an application sub-platform 53. The 3D model library management sub-platform 51 is used to store 3D models. The visual editing sub-platform 52 accesses the 3D model library management sub-platform 51 to obtain 3D models and implement model assembly and 3D scene construction. The application sub-platform 53 manages and implements application scenarios edited by the visual editing sub-platform. The application sub-platform 53 is built using a B / S architecture. The 3D model management sub-platform 51 includes a MySQL database and is built using a B / S architecture. The management platform 5 also includes a display 54.

[0029] In the present invention, the VR output device 1 includes a VR helmet and multi-channel headphones to achieve visual and auditory simulation. The VR input device 2 includes a VR handheld operating handle, which blocks the experiencer's vision from the outside world and guides the user to feel like they are in a virtual environment by tracking eye and head movements. At the same time, it can sense the experiencer's displacement and trigger corresponding scenes.

[0030] In the present invention, the VR position tracking device 3 includes at least two laser locators. Several devices that can emit lasers are installed in the space to emit lasers that scan the space in both horizontal and vertical directions. Multiple laser sensing receivers are placed on the object to be located. By calculating the angular difference between the two beams of light reaching the located object, the three-dimensional coordinates of the object are obtained. When the object moves, the three-dimensional coordinates will also change, so the motion information is obtained and the motion capture is completed.

[0031] In addition to visual and auditory experiences, this utility model utilizes a somatosensory device 4 to enhance the user's actual experience. This somatosensory device incorporates a lifting platform composed of multi-degree-of-freedom electric cylinders. Network communication between the host computer and the dynamic chair is achieved via the UDP protocol. The host computer sends commands to control the extension and retraction of the multi-degree-of-freedom electric cylinders, which in turn drives the upper platform bracket, which in turn drives the upper platform experience chair. This allows for program-implemented actions such as walking, falling, and shaking. The addition of various sensors and devices enables special effects such as electric shock, air blowing, water spraying, and hot air, providing users with a realistic, immersive VR experience and enhancing safety training.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
