[0023] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.
[0024] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
[0025] like Figure 1 and Figure 2 As shown, a fire simulation system includes: a display screen 10, a signal receiver, a simulated fire extinguisher and a simulation controller.
[0026] There are multiple display screens 10, and the multiple display screens 10 are arranged to form a fire simulation space 101; for example, the fire simulation space is surrounded by at least three curved screens to form a 270° surrounding space (such as Figure 1 ), display resolution ≥ 4K, refresh rate 120Hz, support for dynamic flame rendering, and improve the simulation effect of fire through dynamic rendering.
[0027] The signal receiving matrix is equipped with multiple signal receivers, which are arranged on the surface of the display screen; each display screen surface is mounted with a 20×20 receiver array with a spacing of 5cm, supporting infrared or laser signal capture (accuracy ±1°).
[0028] The nozzle of the simulated fire extinguisher is equipped with a signal transmitter; the nozzle of the simulated fire extinguisher has a built-in high-precision signal transmitter, and the transmission frequency of the signal transmitter is 10Hz. The handle of the simulated fire extinguisher is integrated with a pressure sensor and a gyroscope, and the gyroscope is used to detect the inclination angle. The pressure sensor can detect the firefighting strength of the trainees. When the trainees increase their strength, the spraying strength of the fire-extinguishing gas or foam can also be increased synchronously.
[0029] The simulation controller is connected to each display screen, and is used to simulate the formation of a flame image on the display screen with the signal receiver as the fire point. The simulation controller is mainly used for fire point generation, scene rendering, and data analysis.
[0030] In this embodiment, the trainee enters the fire simulation space and performs fire extinguishing operation on the simulated flame image through the simulated fire extinguisher. The flame image is formed with the signal receiver as the fire point. After the signal transmitter of the fire extinguisher fights the signal receiver, the flame image disappears, thereby improving the authenticity of the fire simulation and the simulation training effect.
[0031] In addition, the fire simulation space can accommodate multiple people operating at the same time. Multiple people can conduct simulation training at the same time to improve training efficiency, and can also conduct collaborative firefighting training among multiple people.
[0032] In order to simulate a real fire for training, in one embodiment of the present application, the simulation controller randomly selects one or more signal receivers as fire points to form a flame image. Multiple signal receivers can be used as fire points at the same time to form a larger flame image, or the flame image can be dispersed into multiple ones to increase the difficulty of fire extinguishing.
[0033] In one embodiment of the present application, the fire simulation system further includes a memory, which stores fire scenes under different circumstances; when forming a flame image, the simulation controller randomly retrieves the fire scene from the memory and displays the fire scene on the display screen. For example, the fire scene may be an electrical fire in an office, a spontaneous combustion of a vehicle, or a gas fire in a kitchen, etc. The simulation effect is improved by presenting the fire scene.
[0034] In one embodiment of the present application, the fire simulation system further includes a speaker, which is connected to the simulation controller and is used to play the sound of the simulated fire scene, so that the fire scene is closer to reality. For example, the speaker is a 7.1-channel surround sound system with a maximum sound pressure level of 110dB. Various sound, light, electricity and other measures can also be added to improve the authenticity of the scene.
[0035] In one embodiment of the present application, the signal transmitter is an infrared signal transmitter or a laser signal transmitter; the signal receiver receives the infrared signal or the laser signal to determine that the fire extinguishing operation is completed.
[0036] In one embodiment of the present application, the fire simulation system further includes a timer and a camera, the timer and the camera are connected to a simulation controller, the timer is used to measure the fire extinguishing time, the camera is used to record the fire extinguishing process of the trainee, and the simulation controller outputs a simulation training report based on the fire extinguishing time and the fire extinguishing process. The camera can be Intel RealSense D455, and the camera can sense depth and capture the motion of the trainee. A time can be set, and if the fire extinguishing is not completed within the set time, it can be determined that the simulated trainee can no longer escape and the training has failed.
[0037] In one embodiment of the present application, the fire simulation system also includes a biological monitoring kit, which is wirelessly connected to the simulation controller. The biological monitoring kit is used to detect the heartbeat and body temperature of the trainee, and the simulation controller outputs a training report based on the heartbeat and body temperature of the trainee. The biological monitoring kit can be a smart bracelet. The present application can be used to train professional firefighters by quantifying the HRV (Heart Rate Variability) index to evaluate the psychological stability and stress tolerance of firefighters during the firefighting process. In the firefighting scene, psychological quality directly affects operational performance. As a "biomarker" of psychological state, HRV can evaluate firefighting ability from the following dimensions:
[0038] 1. Emergency decision-making quality, high HRV: The parasympathetic nerves are active, and the trainees can quickly and calmly analyze the fire (such as determining the priority firefighting area), and the decision-making error rate is reduced by about 30% (refer to the experimental data of the National Fire Protection Association in 2022). Low HRV: Overactivation of the sympathetic nerves can easily lead to panic, and mistakes such as blind spraying and ignoring escape routes. 2. Stress resistance, the dynamic changes in HRV reflect the level of stress adaptation: when the fire suddenly changes, HRV drops briefly and then recovers quickly, indicating strong anti-interference ability; HRV remains low and recovers slowly, indicating excessive tension or fatigue. 3. Teamwork efficiency, HRV synchronization research shows that the HRV fluctuation trends of members of efficient firefighting teams are similar (cooperative stress adaptation), and communication errors are reduced by 40%.
[0039] In one embodiment of the present application, an artificial intelligence model is provided in the simulation controller, and a training report is output based on the analysis of the artificial intelligence model. The artificial intelligence model may be YOLOv7 and BiLSTM. The training report may be transmitted remotely, for example, to a mobile phone of a trainer.
[0040] Physiological fusion evaluation: The controller randomly selects N receivers as the initial fire points (N=1~5, increasing with difficulty); calls up scene data from the memory (such as chemical leakage causing explosion), superimposes flame special effects and physical engine simulation of spread; the speakers simultaneously play burning sounds, explosion sounds and structural collapse sound effects.
[0041] Fire extinguishing stage: The trainee holds the simulated fire extinguisher and aims it at the fire point, and the nozzle emits a signal; after the receiver captures the signal, the controller calculates the hit rate:
[0042] Hit rate = number of fire point receptors hit / total number of active fire points × 100% Hit rate = total number of active fire points / number of fire point receptors hit × 100%; the fire intensity dynamically decays according to the hit rate, and the flames in the missed areas expand.
[0043] Evaluation phase: Analyze the standardization of body movements recorded by the camera; evaluate psychological stability in combination with heart rate variability (HRV); and achieve full closed-loop training of "physical operation-virtual feedback-physiological monitoring".
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
