[0037] On the other hand, refer to Figure 2 The embodiment of the present application also provides a method for implementing a fire crowd evacuation device, which is implemented through the above device. The method includes steps S101 and S102.

[0038] S101, the gas sensor collects the carbon monoxide concentration in the environment, the steering gear camera collects the crowd density, crowd flow rate and wall temperature, and the light temperature sensor collects the ambient temperature;

[0039] S102: When the carbon monoxide concentration is greater than a first preset threshold, and / or the ambient temperature is greater than a second preset threshold, the controller controls the alarm in the building or structure to sound an alarm according to the carbon monoxide concentration, ambient temperature, crowd density, and crowd flow rate.

[0040] Further, in the embodiment of the present application, when the carbon monoxide concentration is greater than a first preset threshold value, and / or the ambient temperature is greater than a second preset threshold value; the controller controls the alarm in the building or structure to sound an alarm according to the carbon monoxide concentration, ambient temperature, crowd density, and crowd flow rate, including:

[0041] The controller controls the indicator light of the target channel in the building or structure to light up and the audio player to send out an alarm message according to the carbon monoxide concentration, ambient temperature, crowd density and crowd flow rate; the target channel is the optimal channel obtained by the controller.

[0042] The specific implementation principle of this application is described below with reference to the accompanying drawings:

[0043] Reference Figure 3 The present invention provides a fire crowd dispersal device based on the combination of sound and light, including a single chip microcomputer 1, a steering gear control 2, a thermal imaging camera 3, an audio amplifier 4, a light temperature sensor 5, a CO sensor 6, an indicator light 7, and a WiFi module 8. In some embodiments, the steering gear control 2 and the thermal imaging camera 3 can be integrated into a steering gear camera.

[0044] MCU 1 uses the RTOS real-time operating system to schedule time slices. The servo turns 1° every 50ms. Thermal imaging collects crowd density, crowd flow rate and wall temperature. After Kalman filtering, normalization is performed. The importance of each factor is analyzed through simulated annealing. Finally, deep learning and CFD algorithm analysis channels are performed.

[0045] The light temperature sensor 5 can determine whether the temperature reaches the threshold value and release the low-power sleep mode. The master microcontroller operates the slave microcontroller through the RTOS real-time operating system. The RTOS operating system schedules the thermal imaging camera through time slices to obtain information from corners. The light temperature sensor and the CO sensor directly obtain information. The slave microcontroller transmits the data to the master microcontroller for time slice scheduling and uploads it to the cloud for display through the Wi-Fi module. Then the slave microcontroller receives the instructions of the master microcontroller to indicate the route with the indicator light, and the audio amplifier sends a voice broadcast to indicate the escape route.

[0046] In the above device, the slave microcontroller is not connected to the Wi-Fi module. When the light temperature sensor value changes dramatically, the master and slave microcontrollers will be awakened through the RCC clock to enable other modules. The data obtained by the light temperature sensor is obtained after filtering to prevent abnormal awakening due to inaccurate sampling. After the microcontroller works, it performs collaborative operations through the RT OS real-time operating system, and one of the microcontrollers is responsible for data processing and analysis as the host, and the other microcontrollers are slaves to perform specific operations. The light and temperature sensor collects ambient temperature data, the CO sensor obtains the concentration value of CO (carbon monoxide), and the servo infrared sensor operated by time slice scheduling is responsible for obtaining crowd density and crowd flow rate. When the fire spreads, the indicator light is enabled to indicate the direction, and the voice broadcast issued by the audio amplifier is used to prompt the CO concentration and escape channel. The escape channel is obtained by normalizing the data, calculating the importance of each component through the simulated annealing algorithm, and finally importing the CFD model after the deep learning algorithm. The 3D model of the building must be imported first, and then the location of the fire source is obtained through the light and temperature sensor. If there is a linkage surveillance camera, it is used in conjunction with the surveillance camera. At the same time, the CO sensor and thermal imaging camera obtain the crowd density and crowd flow direction at each point, as well as the CO concentration value. Finally, the CFD model is imported to obtain the corresponding escape channel, and then the slave microcontroller receives instructions to adjust the indicator light, and the audio player issues a warning sound to notify the crowd of the location and direction of the escape channel. In addition, the main control microcontroller transmits cloud app data through the Wi-Fi module, so that rescuers can quickly carry out rescue and clear the fire source. The single-chip computer connected by the real-time operating system realizes the coordinated work of multiple components, improving the efficiency and response speed of the device. The light temperature sensor detects the change of ambient temperature in real time and responds accordingly when a fire occurs. The CO sensor detects the change of CO concentration in real time and responds accordingly when a fire occurs. The thermal imaging camera determines the flow rate of the crowd by calculating the infrared reflection rate, and knows the time when the fire spreads to this place through the refractive index of the high temperature area, and obtains the crowd density through the change of the crowd flow rate. The role of the servo is to achieve the effect of simulating radar by scheduling the real-time change of angle through time slices. The role of the indicator light is to inform the escapee of the danger situation at this point through red, yellow and green to inform the escapee of the escapee. If they are all in red, try to get materials on the spot and wait for rescue.

[0047] The audio amplifier is used to amplify the warning sound stored in advance, and amplify it through the differential circuit to remind people of the location of the escape route. The audio amplifier amplifies and processes the audio signal through an analog circuit or a digital signal processor (DSP). The WiFi module is used to transmit data to the cloud, and the app displays the CO concentration temperature, indicator lights, and rescue status at each point.

[0048] Through this device, this embodiment can achieve the combination of sound and light to disperse and guide the crowd when a fire occurs, thereby improving the efficiency and safety of escape. The device uses technical means such as temperature sensors and thermal imaging cameras for real-time monitoring and analysis, and combines sound and light path indications to provide people with clear escape guidance, thereby improving the orderliness and efficiency of fire escape.

[0049] Reference Figure 4 Real-time monitoring is a vital part of the sound and light dispersal device. It can monitor the smoke concentration, temperature, pressure and other parameters of the fire scene in real time, and transmit the data to the sound and light diffuser, so as to achieve the purpose of precise control of the fire scene. Real-time monitoring usually uses infrared, ultraviolet, laser and other technologies to detect smoke, which can ensure that the fire protection system responds and starts in the shortest time.

[0050] CFD algorithm is a common numerical simulation method in fire sound and light dispersal devices. In this embodiment, the 3D model of the corresponding location is imported. The model is:

[0051]

[0052] Where ρ is the fluid density; V is the velocity vector, u, v, w are the velocity components of the fluid at point (x,,z) at time t; p is the pressure; f is the external force per unit volume of fluid. If only gravity is considered, then f=ρg; the constant μ is the dynamic viscosity.

[0053] At this time, this embodiment uses the conservation of fluid momentum, the conservation of energy formula, and the NS formula to obtain the CO concentration of the nearby points obtained by the CO sensor, the light temperature sensor, and the thermal imaging camera. The temperature and the change of its CO concentration can not only objectively reflect the flow rate, but also solve the predicted CO concentration and temperature of each network cell. At this time, the boundary conditions can be used, such as by setting the temperature CO threshold at 5m away from the device, to determine whether the threshold point has been reached, and then predict the possibility of fire, and then use the audio amplifier and indicator light to remind the escapees in real time whether it is suitable to take this road. The CFD algorithm can simulate the complex environment and flow field of the fire scene, and provide accurate and reliable data support for the design and optimization of the fire sound and light dispersal device. At the same time, the CFD algorithm can also simulate various smoke diffusion parameters under different fire conditions, and achieve more accurate fire fighting through cooperation with the RTOS real-time operating system and other hardware equipment.

[0054] Deep learning technology continuously extracts data from fire scenes simulated by computational fluid dynamics (CFD) algorithms, conducts in-depth analysis and learning on these data, and thus builds an intelligent model that can identify complex environmental factors in fires and predict smoke diffusion patterns. The model uses the CO concentration and temperature of each point obtained by the CFD algorithm. Since the CO flow rate is linearly related to its temperature, the model uses regression analysis in time series prediction to derive the CO concentration and temperature of the point in the future, so as to prevent the fire from spreading to the point after a while after the crowd runs to the point. Through continuous machine learning, the understanding and prediction of fire spread behavior are continuously optimized. After repeated training and verification, the deep learning model can accurately identify the best escape route under specific fire conditions, taking into account the shortest and safest route from the fire source to the safe exit, while avoiding high temperature and highly toxic smoke areas, and providing users with a reliable and intelligently optimized escape plan. This solution is not only based on the accuracy of physical simulation, but also integrates the adaptive and generalization capabilities of machine learning algorithms, significantly improving the accuracy and practicality of fire escape route prediction.

[0055] In summary, the fire crowd evacuation device of the present application has the following advantages:

[0056] This application can provide timely warnings. The sound and light combined device can quickly emit high-intensity sound and flashing light to effectively convey fire alarm signals to the crowd. This can help people quickly realize the existence of fire and increase their awareness of danger.

[0057] This application can guide the crowd to move. The device is usually placed in the key position of the fire evacuation passage, and guides people to quickly leave the fire scene through the safe passage by emitting sound and light. This helps to reduce the confusion and panic of the crowd and improve the efficiency of evacuation.

[0058] This application can improve visibility. Fire scenes are often accompanied by thick smoke and darkness, which makes it difficult for people to escape. The flashing light of the sound and light combined device can effectively improve visibility, help people better identify escape routes and obstacles, and reduce the occurrence of accidents.

[0059] This application can reduce the risk of casualties. When a fire occurs, it is crucial to disperse the crowd in a timely and effective manner. The sound and light combined device can help people quickly leave the fire scene and reduce the risk of being trapped, injured or killed. It plays a positive role in protecting people's lives and safety.
