It is mainly used in the military, medical and industrial fields.

[0003] A search revealed that publication number CN115862411A discloses a high-speed gliding simulation training device and method for bobsleigh and luge athletes. The device includes a motion-sensing control device, a bobsleigh and luge vibration and posture feedback control device, a competition venue stereoscopic audiovisual simulation module, and a physical interface compatible with different bobsleighs and luges. The bobsleigh and luge vibration and posture feedback control device is connected to the motion-sensing control device. The motion-sensing control device, the bobsleigh and luge vibration and posture feedback control device, and the competition venue stereoscopic audiovisual simulation module are connected via a microprocessor running a virtual bobsleigh and luge gliding program. The bobsleigh and luge vibration and posture feedback control device is used to simulate the posture during bobsleigh and luge movement and provide tactile feedback to the athlete. The physical interface is installed on the bobsleigh and luge vibration and posture feedback control device. This invention can effectively improve the convenience and safety of athlete training. The inventors discovered the following problems with the existing technology during the development of this invention:

[0004] Existing VR simulation training equipment generally uses the FDS engine to simulate various environmental scenarios. However, when simulating complex scenarios, the FDS engine has insufficient real-time computing power, which leads to a delay between the foam coverage effect and the actual fire feedback. For example, virtual foam has been sprayed but the fire has not been weakened. In addition, traditional VR simulation training equipment does not have a fixed place to store VR headsets after use, which makes it difficult to find or lose VR headsets.

[0005] Therefore, a VR simulation training device for a compressed air foam vehicle controller is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a VR simulation training device for a compressed air foam vehicle controller to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a VR simulation training device for a compressed air foam vehicle controller, comprising a VR headset and a physical control console mechanism. The physical control console mechanism is placed above the VR headset, and the physical control console mechanism includes a vehicle control component, a system initialization component, a seat component, and a display screen. The system initialization component is placed on the side of the vehicle control component, and the display screen is placed above the system initialization component. The seat component is placed on the side of the system initialization component away from the vehicle control component, and the seat component includes a vehicle seat and a vibration motor. The vibration motor is installed under the vehicle seat.

[0008] Preferably, the vehicle control assembly includes a brake pedal, an electronic parking brake, a gear shift lever, and outrigger control buttons. The electronic parking brake is placed above the brake pedal, the gear shift lever is placed to the side of the electronic parking brake, and the outrigger control buttons are placed on the side of the gear shift lever away from the electronic parking brake.

[0009] Preferably, the system initialization component includes a main power button, an on-board computer button, an opening component, a valve component, and an unlocking component. The on-board computer button is placed on the side of the main power button, the opening component is placed on the side of the on-board computer button away from the main power button, the valve component is placed on the side of the opening component away from the on-board computer button, and the unlocking component is placed on the side of the valve component away from the opening component. The unlocking component includes a proportional knob and a foot brake valve plate, and the foot brake valve plate is placed below the proportional knob.

[0010] Preferably, the opening component includes an air compressor button, a foam pump button, and a water pump button, with the foam pump button placed to the side of the air compressor button and the water pump button placed on the side of the foam pump button away from the air compressor button.

[0011] Preferably, the valve assembly includes an inlet valve handle, a foam valve button, and an air vent button, with the foam valve button located on the side of the inlet valve handle and the air vent button located on the side of the foam valve button away from the inlet valve button.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with existing technologies, this VR simulation training device for a compressed air foam truck controller improves the real-time performance of complex scenarios by using a lightweight fire model through a physical control console mechanism. While retaining the ability to simulate the basic physical characteristics of fire, it also optimizes the calculation model. It adopts adaptive mesh technology, which can dynamically adjust the mesh density according to the development of the fire. In areas where the fire is stable and changes slowly, a relatively large mesh size is used to reduce unnecessary calculations. In critical areas where the flame front and heat flux density change drastically, the mesh is automatically refined to ensure simulation accuracy.

[0014] 2. Compared with the existing technology, this VR simulation training device for a compressed air foam vehicle controller has a special placement component for the VR headset installed above the armrest of the vehicle seat. This allows the VR headset to be fixed in place when not in use, preventing its loss. When retrieving the VR headset, the operator needs to activate the cylinder above the armrest to retract a portion of the push rod, thereby removing the VR headset stuck inside.

At this time, the display screen 6 will show the training scenario for Training 1, and the vibration motor 8 under the seat 7 will also vibrate, simulating the state when the compressed air foam vehicle starts. The operator needs to control the vehicle control assembly 3 to pass through the training scenario. After the operator passes through the training scenario, they can choose to leave or choose the training scenario 2 to continue training. When operating the training scenario 2, the operator needs to operate the system initialization assembly 4.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, the vehicle control assembly 3 includes a brake pedal 9, an electronic parking brake 10, a gear shift lever 11, and a outrigger control button 12. The electronic parking brake 10 is placed above the brake pedal 9, the gear shift lever 11 is placed on the side of the electronic parking brake 10, and the outrigger control button 12 is placed on the side of the gear shift lever 11 away from the electronic parking brake 10.

[0027] In a preferred embodiment, the system initialization component 4 includes a main power button 13, an on-board computer button 14, an opening component 15, a valve component 16, and an unlocking component 17. The on-board computer button 14 is placed on the side of the main power button 13. The opening component 15 is placed on the side of the on-board computer button 14 away from the main power button 13. The valve component 16 is placed on the side of the opening component 15 away from the on-board computer button 14. The unlocking component 17 is placed on the side of the valve component 16 away from the opening component 15. The unlocking component 17 includes a proportional knob 24 and a foot brake valve plate 25. The foot brake valve plate 25 is placed below the proportional knob 24.

[0028] In a preferred embodiment, the activation component 15 includes an air compressor button 18, a foam pump button 19, and a water pump button 20. The foam pump button 19 is placed on the side of the air compressor button 18, and the water pump button 20 is placed on the side of the foam pump button 19 away from the air compressor button 18.

[0029] In a preferred embodiment, the valve assembly 16 includes an inlet valve handle 21, a foam valve button 22, and an vent valve button 23. The foam valve button 22 is placed on the side of the inlet valve handle 21, and the vent valve button 23 is placed on the side of the foam valve button 22 away from the inlet valve button.

[0030] The working process of this utility model is as follows: First, when the operator needs to conduct VR simulation training on the compressed air foam vehicle, they first need to sit on the seat assembly 5 of the physical control console mechanism 2, and then activate the cylinder in the armrest of the seat 7 to remove the VR headset 1, which is held in place by the push rod. After removing the VR headset 1, the operator needs to put it on their face and then activate the button of the VR simulation training device to start it running. At this time, the display screen 6 will show the training scenario required for training one, and the vibration motor 8 under the seat 7 will also vibrate, simulating the state when the compressed air foam vehicle starts. The scenario simulated in training one is... In the event of a fire near a chemical plant in windy conditions, the operator must first maneuver the simulated compressed air foam truck to an upwind location 15 to 30 meters from the fire source. If the vehicle is incorrectly positioned, a warning message will appear on display screen 6. Once the vehicle is correctly positioned, the operator must use the vehicle control unit 3 to park the simulated compressed air foam truck. The operator must first depress the brake pedal 9, then use the electronic handbrake 10, and engage the gear shift lever 11. After this, the operator must activate the outrigger control button to lower the outriggers in the following order: left front outrigger, ... The right front outrigger, left rear outrigger, and right rear outrigger provide support for the compressed air foam vehicle, ensuring its tilt angle is less than 3 degrees. If an operational error occurs, display screen 6 will show a warning message and repeat the previous operational scenario for the operator to practice repeatedly. After successfully completing training scenario one, the operator can choose to leave or continue training in training scenario two. When operating in training scenario two, the operator needs to operate the system initialization component 4. Training scenario two involves practicing the use of a fire extinguishing device. First, the operator must activate the main power button 13 of the system initialization component, and then turn the onboard computer button 14. This allows the operating system in the compressed foam truck to be used. After the onboard computer is working properly, the operator needs to first turn the air compressor button 18 of the start component 15, wait 30 seconds, and then press the foam pump button 19 and the water pump button 20 in sequence. After the operation is completed, the operator also needs to turn the water inlet valve handle 21 clockwise four turns, and then press the foam valve button 22 and the air outlet valve button 23 in sequence. Then, turn the proportional knob 24 of the unlock component 17 to adjust the mixing ratio of water, foam and air. Finally, press the foot brake valve plate 25 to unlock the water spray gun. The above is the working principle of the VR simulation training device of the compressed air foam truck controller.
