[0002] In recent years, with the acceleration of urbanization, the number of motor vehicles has increased rapidly, and the risk of parking lot fire accidents has gradually increased. Traditional parking lot fire extinguishing methods mostly rely on fixed sprinkler systems and manual fire extinguishing devices. These systems have problems such as slow response speed, limited coverage, and inability to quickly locate the fire source in actual application.

[0003] Existing parking lot fire protection systems usually use fixed sprinkler devices and smoke detectors. When a fire occurs, the smoke detector senses the smoke and triggers the fixed sprinkler device to extinguish the fire. This system relies on the spread of smoke to detect fires and uses sprinkler heads in fixed positions to extinguish the fire. Existing fire protection systems have the following defects: (1) Slow response speed: The fixed sprinkler system needs to wait for the smoke to spread to the detector before it can be triggered, resulting in the inability to control the fire in time at the early stage; (2) Limited coverage: The sprinkler head is fixedly installed and cannot adjust the spray direction and coverage according to the location of the fire source; (3) Inability to quickly locate: The system cannot accurately locate the fire source, resulting in low fire extinguishing efficiency.

[0104] Path optimization objective: Minimize the total path of the device movement so that the device can reach the fire source and perform fire extinguishing operations as quickly as possible.

[0105] Mathematical model: Assume that the speed of the device during movement is v(t), and the movement path is P(t) = (x(t), y(t), z(t)), and it is necessary to minimize the total movement time T from the current position to the fire source position total .

[0106] The objective function is: where

[0107] Kinematics constraints: The movement of the device is limited by the acceleration and maximum speed of each movement driving mechanism. Consider the following constraint conditions: and v max ≤ v(t) ≤ v min .

[0108] Optimization objective: By combining path planning and kinematics constraints, the system can calculate the optimal three-dimensional path from the current state to the fire source.

[0109] The system uses sensor data (such as infrared video information and position data) to calculate the three-dimensional position (x f , y f , z f ) of the fire source, and then optimizes the movement paths of the camera and the sprinkler.

[0110] After the fire source position is determined, by calculating the path optimization model, select the shortest path and the fastest response method to ensure that the device can reach the target and perform fire extinguishing in the shortest time.

[0111] The system calculates the relative position and angle between the device and the fire source in real time and dynamically adjusts the movement direction of the device according to the movement path model to ensure that the device accurately aims at the fire source for fire extinguishing.

[0112] In an embodiment of the present invention, the intelligent fire extinguishing system for the parking lot of the present invention can use a flexible fire blanket, and the following model can be constructed:

[0113] (1) Mechanical model of elastic locking fire blanket;

[0114] The flexible fire blanket is provided with an elastic mechanism and a locking mechanism; the elastic mechanism is arranged on the fire blanket body, and is rolled up in the first state and unrolled in the second state, and can be locked by the locking mechanism in the rolled up state. The locking mechanism can be a solenoid valve, or can be through electromagnetic adsorption; the elastic mechanism can be a structure such as a shrapnel, a rubber band, or other elastic mechanisms. Assuming that the fire blanket is released through the solenoid valve, the elastic mechanism will generate elastic force when it unfolds, and the speed and acceleration are related to the elastic coefficient k and the elongation ΔL.

[0115] Elastic force formula: The force F generated by an elastic mechanism (such as a rubber band or other elastic mechanisms) when it pops out can be expressed as: F = k·ΔL; where ΔL = L final -L initial , L final is the final length of the elastic mechanism, L initial is the original length of the elastic mechanism.

[0116] Acceleration and velocity model: Under the elastic force of the elastic mechanism, the acceleration a of the fire blanket is: where m is the mass of the fire blanket. Using the law of conservation of energy, we can calculate the velocity v and the deployment time t, the final velocity v final It can be approximated as: where h m is the initial installation height of the fire blanket and g is the acceleration due to gravity.

[0117] Deployment time model: By controlling parameters (such as the timing of the solenoid valve disconnection, the elastic coefficient of the elastic mechanism, the hysteresis time, etc.), the deployment time t of the fire blanket can be accurately calculated. This time should meet the conditions of maximizing the coverage area and minimizing the deployment time: Use optimization algorithm to adjust elastic coefficient k and installation height h m , making the fire blanket deploy faster and cover a larger area.

[0118] After receiving the fire source information, the control system calculates the optimal deployment path according to the fire source location, the installation height of the fire blanket and the deployment model, and adjusts the operation of the solenoid valve in real time to ensure the rapid deployment of the fire blanket. The fire source status is displayed in the background scheduling display system to ensure that the fire blanket can quickly locate and cover the fire source area.

[0119] When fires occur in multiple parking spaces at the same time, the system uses a mathematical model of the target vehicle's position to dynamically calculate the deployment position and sequence of the fire blanket to ensure that multiple fire sources are dealt with in a timely manner.

[0120] In addition, the parking lot intelligent fire extinguishing system of the present invention can also construct a dynamic deployment model for multiple fire situations; when multiple fire sources occur simultaneously, the system dynamically deploys fire extinguishing equipment by calculating the relative position, fire source intensity and other information of each fire source using a multi-objective optimization algorithm.

[0121] The shortest path calculation between the fire source and the fire extinguishing equipment: Use the Dijkstra algorithm to calculate the shortest path from the current position of the fire extinguishing equipment to each fire source.

[0122] Dynamically allocate resources based on the available status of fire-fighting equipment (such as current mobile status, distance, load, etc.). Set the objective function: where d i is the distance from the fire source to the equipment, v i is the current speed of the device, r i : Device response time (the time from receiving the command to starting to move, in seconds); c i :Equipment comprehensive fire extinguishing capacity coefficient (such as the flow rate Q (L / s) of the high-pressure spray gun and the coverage area A (m 2 ), c i =λQ+μA); α, β: weight coefficients, dynamically adjusted according to the parking lot size and equipment performance (e.g. α=0.2, β=0.8); optimize the path and ensure that the fire extinguishing task is completed in the fastest time. i The impact of equipment startup delay on fire extinguishing efficiency can be quantified; the introduction of c i Equipment with stronger fire-fighting capabilities can be dispatched preferentially (such as high-pressure spray guns for large-area fire sources and fire blankets for local fire sources); weight coefficients α and β support dynamic strategy adaptation.

[0123] According to the urgency of multiple fire sources, the priority of fire extinguishing equipment is assigned to each fire source and dispatched. The scheduling algorithm can be optimized based on greedy strategy or genetic algorithm to minimize the fire extinguishing time.

[0124] In the background dispatching system, a dynamic dispatching algorithm is used to deploy fire-fighting equipment in real time based on the location information of different fire sources, ensuring that the equipment closest to the fire source is dispatched first.

[0125] The system automatically adjusts the equipment's operating trajectory according to the status of different equipment to ensure that all fire sources can be effectively extinguished in the shortest time possible.

[0126] Change the model update mechanism from fixed time interval to event-triggered update. The trigger conditions may include:

[0127] Fire source event: a new fire source is detected, the fire source intensity changes beyond the threshold (ΔT>50°C), or the fire source position shifts (Δd>1m);

[0128] Equipment events: equipment status changes (such as failure, task completion, battery power below 20%);

[0129] Environmental events: Sudden changes in traffic volume (such as a 50% increase in the frequency of vehicles entering and exiting).

[0130] Mathematical model update rules: Update condition: ∪{ΔT, Δd, equipment status, vehicle flow} ≥ threshold.

[0131] The present invention can reduce redundant calculations and trigger model updates only when key events occur; it can improve the system response speed and adapt to the dynamic environment of the parking lot (such as dense traffic during peak hours and sudden fires).

[0132] Scheduling process after objective function optimization:

[0133] Input: Fire source location set {(x f ,y f ,z f )}, device status set {d i ,v i ,r i ,c i}; Calculate priority weight:

[0134] Optimizing min∑w using genetic algorithm i , generate the equipment-fire source matching matrix; dynamically adjust α and β to adapt to different scenarios (such as focusing on firefighting capability at night with low traffic volume and focusing on response speed during the day).

[0135] The system conducts comprehensive optimization based on multi-dimensional information such as fire source intensity, location of fire-fighting equipment, equipment load, etc., to ensure that resources are maximized while avoiding waste of resources.

[0136] The present invention further discloses a fire extinguishing control method of the parking lot fire extinguishing system. Figure 7 Schematic diagram of a fire extinguishing control method according to an embodiment of the present invention. Figure 8 This is a flow chart of a fire extinguishing control method in one embodiment of the present invention; please refer to Figure 7 , Figure 8 , the fire extinguishing control method comprises:

[0143] In one embodiment of the present invention, the fire extinguishing control method may further include:

[0144] Steps for constructing the mathematical model of the target vehicle position: constructing the mathematical model of the target vehicle position by learning the position data of the infrared temperature measuring device, the coordinates of each pixel point corresponding to the high temperature area detected by the infrared temperature measuring device, and the identification data of the parking space where the high temperature appears;

[0145] Parking space determination step: Use the target vehicle position mathematical model to determine the parking space position, input the position data of the infrared temperature measuring device and the coordinates of each pixel point detected in the high temperature area into the target vehicle position mathematical model, and the target vehicle position mathematical model generates corresponding parking space identification data, thereby determining the parking space position.

[0146] The parking lot fire extinguishing system achieves fast, accurate and efficient fire fighting through the collaborative work of hardware and software. The system is installed on the aviation aluminum frame above the parking spaces in the parking lot. The main equipment includes movable infrared temperature sensing cameras, high-pressure fire extinguishing liquid nozzles, flexible fire blankets, etc., all installed on movable slide rails, supporting three-dimensional movement to achieve maximum coverage and fastest response speed.

[0147] The workflow includes:

[0148] 1. Fire monitoring: When a fire occurs in a parking space in the parking lot, the movable infrared temperature sensing camera monitors the temperature changes in real time and identifies the location of the fire source.

[0149] 2. Information transmission and processing: The camera transmits the fire source information to the central control system, and the system analyzes the location and severity of the fire.

[0150] 3. Equipment dispatch and response: According to the location of the fire source, the central control system dispatches the flexible fire blanket and high-pressure fire extinguishing liquid nozzle to move above the fire source.

[0155] 6. Backstage monitoring and notification: The backstage dispatch display system updates the fire status in real time and notifies personnel to handle the fire on site.

[0156] Overall working logic

[0157] Input stage: Temperature sensor camera data: Use a movable infrared temperature sensor camera to monitor temperature changes in the parking lot in real time and collect data related to fire sources.

[0158] Processing stage: The central control system calculates the location of the fire source: The central control system receives data from multiple temperature sensing cameras, calculates and analyzes the location of the fire source, and determines the specific location and intensity of the fire.

[0159] Output stage: Dispatch fire-fighting equipment: According to the location of the fire source and the intensity of the fire, the central control system automatically dispatches the corresponding fire-fighting equipment. Execute fire-fighting operations: Execute fire-fighting operations, which may include the activation and operation of high-pressure fire-fighting liquid nozzles, flexible fire-fighting blankets, emergency fire-fighting robots and other equipment. Backstage monitoring display: Real-time update of fire-fighting progress, display of fire source conditions, equipment status, fire-fighting operations and other information, to ensure that backstage staff can fully monitor the fire-fighting process.

[0160] In one use scenario of the present invention, the fire extinguishing control method of the present invention includes the steps of constructing a mathematical model of the position of a target vehicle;

[0161] Each parking space in the parking lot has a unique mark, and each mark corresponds to a parking position. The infrared camera temperature monitor (temperature sensing camera) can detect the temperature of the fire source in real time, provide infrared video data, and its location is also monitored in real time (obtained through the position sensor).

[0162] Definition of input data. Position data of infrared camera temperature monitor: Let the position be (x cam ,y cam ), which represents the two-dimensional coordinates of the camera location. Infrared video data: Infrared image data I(x,y) obtained from an infrared camera temperature monitor, where I(x,y) represents the temperature value at position (x,y) in the image. Marker data: Each parking space in the parking lot has a marker m i , and its corresponding position is Used to indicate the parking space. Relationship between the target vehicle location and the abnormal temperature area: The temperature abnormal area caused by the fire source will have features in the infrared image, marking the possible location of the target vehicle.

[0163] Inference of the target vehicle position based on infrared data. Assuming that the abnormal temperature area (e.g., high temperature area) in the image is caused by a fire source, the target vehicle is located near the center of the area. Infrared video data can provide the spatial location range of the fire source. fire , and the temperature distribution of the area. According to the location of the temperature anomaly in the image (x fire ,y fire ), the location of the target vehicle can be inferred. The boundary of the abnormal temperature area is extracted through image processing algorithm, and the precise location of the fire source is estimated.

[0164] The mathematical model of the target vehicle location is established. The model assumes that the target vehicle is located at the center of the abnormal temperature area detected by the infrared camera temperature monitor. According to the temperature distribution in the video, the coordinates of the target vehicle (x vehicle ,y vehicle ) can be calculated by the following formula: Where f is a function that represents the mapping relationship between the target vehicle position based on infrared video data, camera position, and parking space markings.

[0165] Geometric model for target vehicle positioning: Considering the parking space position and the relative position of the target vehicle in the parking lot, the geometric relationship between the parking space marking and the camera and the fire source can be expressed as follows: where d vehicle is the Euclidean distance between the target vehicle and the camera. Using the relative distance between the target vehicle and the fire source and the parking space mark, the specific location of the target vehicle in the parking lot can be further calculated.

[0166] Dataset construction: A large amount of infrared video data and target vehicle data corresponding to the fire source in the parking lot are collected to build a training dataset. Each data point includes an infrared image, the actual location of the vehicle, and the corresponding temperature data.

[0167] Supervised learning: Use regression algorithms in machine learning (such as linear regression, support vector regression, neural networks, etc.) to train the mathematical model of the target vehicle position. The goal of training is to minimize the error between the target vehicle position output by the model and the actual vehicle position: in is the actual target vehicle position, is the position predicted by the model.

[0168] Optimization of the mathematical model of the target vehicle position. Through the training optimization process, the model can gradually improve the prediction accuracy, and finally accurately infer the location of the target vehicle based on the infrared video data and the location of the fire source. In practical applications, the control module can obtain the position data and infrared video data of the infrared camera temperature monitor in real time, and calculate the location of the target vehicle in real time based on the mathematical model of the target vehicle position.

[0169] The infrared camera temperature monitor obtains the temperature data of the parking lot in real time and sends it to the control module. According to the mathematical model of the target vehicle position, the position of the target vehicle is calculated, and combined with the parking space mark and the position of the equipment, the corresponding fire-fighting equipment (such as fire blankets, sprinklers, etc.) is dispatched for precise fire extinguishing.

[0170] The target vehicle positioning module uses the constructed mathematical model to calculate the position of the target vehicle in real time and deploy fire-fighting resources based on it.

[0171] When multiple fire sources occur, the system can use the mathematical model of the target vehicle position to dynamically adjust the position and working order of the fire extinguishing equipment. By combining the location data of multiple fire sources and the position of the target vehicle, the control module can optimize resource scheduling to ensure that each fire source receives the best fire extinguishing treatment.

[0172] During system operation, the mathematical model of the target vehicle position can be dynamically adjusted through real-time data feedback to optimize the positioning accuracy of the target vehicle and the fire extinguishing effect. For example, when the system detects temperature changes or equipment failures in the parking lot, the position of the target vehicle can be automatically updated to ensure that the fire extinguishing process is not interrupted.

[0173] In order to accurately obtain the three-dimensional location information of the fire source and enable the equipment (camera, sprinkler, fire blanket) to be effectively moved and positioned, the three-dimensional location of the fire source needs to be determined.

[0174] Infrared cameras (thermal cameras) can provide spatial location data of fire sources. Infrared cameras detect the thermal radiation of fire sources and generate infrared images or videos. The abnormal temperature areas in these images correspond to the location of the fire sources.

[0175] Assume a fixed camera position (x cam ,y cam ,z cam), the abnormal area position of the fire source in the image is extracted through image processing, and the three-dimensional position is calculated through geometric relationship based on the camera's viewing angle and focal length: Depth = f(x cam ,y cam ,pixel coordinates of fire), where Depth is the depth information and f is a function calculated by known camera parameters, reflecting the spatial mapping relationship of the camera.

[0176] Precise alignment of the sprinkler nozzle is a critical step in the fire extinguishing process, and it is necessary to ensure that the sprinkler nozzle can continue to aim at the fire source to extinguish the fire.

[0177] The sprinkler head needs to have enough degrees of freedom to move and adjust the angle. This patented design uses a servo motor or a stepper motor to control the pitch and rotation angle of the sprinkler head so that the sprinkler head can adjust its direction and accurately point to the fire source.

[0178] Positioning control system: The movement of the nozzle is directed by the control module in real time. The control module adjusts the angle of the nozzle according to the three-dimensional coordinates of the fire source: θ 喷头 =atan2(y 火源 -y 喷头 , x 火源 -x 喷头 ), where θ 喷头 is the rotation angle of the nozzle, (x 喷头 ,y 喷头 ) and (x 火源 ,y 火源 ) are the two-dimensional coordinates of the nozzle and the fire source. According to this angle, the nozzle is controlled to aim at the fire source.

[0179] Pitch and rotation angle calculation: Once the three-dimensional coordinates of the fire source are calculated, the relative position between the sprinkler and the fire source can be calculated using the geometric model. The relative position between the sprinkler and the fire source can be described by distance and angle:

[0180] Vertical direction (pitch angle): θ 俯仰 = atan2(z 火源 -z 喷头 , d 水平 ) Among them, z 火源 and z 喷头 is the position of the fire source and the sprinkler in height (Z axis), d 水平 is the horizontal distance between them.

[0181] Horizontal direction (rotation angle): θ 旋转 =atan2(y 火源 -y 喷头 , x 火源 -x 喷头)This angle is used to ensure that the sprinkler head is always facing the fire source.

[0182] The sprinkler usually has a fixed spraying range (such as the sprinkler's spraying angle and water flow), so the size of the fire source and the sprinkler's coverage capacity need to be considered to ensure that the sprinkler can cover the entire fire source area. The control system will dynamically adjust the relative position of the sprinkler and the fire source by calculating the size of the fire source and the sprinkler's spraying radius to maximize coverage of the fire source area.

[0183] The relative position between the fire source and the equipment is the key to controlling the precise movement of the equipment. The relative position between the fire source and the equipment can be accurately calculated by the following methods:

[0184] (1) Calculation of the distance between the fire source and the equipment. Euclidean distance calculation: Once the three-dimensional position of the fire source and the three-dimensional position of the equipment (camera, sprinkler, etc.) are determined, the distance between the fire source and the equipment can be calculated using the Euclidean distance formula: This distance is the basis for the movement and positioning of the device.

[0185] (2) Path planning and optimal movement of equipment. Dynamic path planning: Based on the relative position between the fire source and the equipment, the system will calculate the optimal path of the equipment in real time. The most commonly used path planning algorithms include the Dijkstra algorithm, which can calculate the shortest path from the current equipment location to the fire source location, ensuring that the equipment can be quickly and effectively moved to the fire source area for fire extinguishing.

[0186] (3) Dynamic adjustment of equipment.

[0187] Real-time adjustment: If the fire source changes (such as wind direction changes, fire source location moves, etc.), the control system will calculate the new device position in real time and adjust the device's motion trajectory so that the device can always accurately approach the fire source.

[0188] Multi-device coordination: If there are multiple devices in the system (such as multiple sprinklers, fire blankets, etc.), the system will dynamically dispatch the devices based on the relative position of each device to the fire source to achieve multi-point fire extinguishing. The relative positions between devices can be calculated using the same Euclidean distance and dispatched based on these positions.

[0189] Use infrared cameras and temperature sensors to monitor abnormal temperature areas in the parking lot in real time, and combine image processing technology (such as infrared video analysis and temperature data analysis) to identify and locate multiple fire sources.

[0190] The system will analyze the data from each camera or sensor, extract the specific location of each fire source through image segmentation or region detection algorithm, and obtain the three-dimensional coordinates of multiple fire sources.

[0191] Once multiple fire sources are detected, the system will automatically identify the specific location of each fire source through geometric inference and deep learning technology. For example, suppose the system has located multiple fire source areas (x 1 ,y 1 ,z 1 ),(x 2 ,y 2 ,z 2 ),...,(x n ,y n ,z n ), these location data will become the basis for subsequent equipment scheduling.

[0192] Deep learning and optimization algorithms: The system can further optimize fire source detection and positioning accuracy through machine learning models (such as convolutional neural networks (CNNs), image segmentation algorithms, etc.), ensuring that the system can accurately identify and distinguish multiple fire sources even in complex fire environments.

[0193] Once the fire source is monitored and located in real time, the next step is how to properly allocate firefighting equipment among multiple fire sources. The core issue of equipment scheduling is how to dynamically allocate firefighting resources based on factors such as the urgency of the fire source, the distance of the firefighting equipment, and the availability of the equipment.

[0194] Priority allocation: Based on the intensity, scale and threat to the surrounding environment of the fire source, the system will assign a priority to each fire source (such as fire source temperature, fire source spread speed, etc.). Fire sources with high priority will be dispatched first.

[0195] Scheduling strategy: The system uses greedy algorithms or heuristic algorithms (such as A* algorithm, genetic algorithm, particle swarm algorithm, etc.) to decide which fire extinguishing equipment should prioritize which fire source. For example, fire extinguishing equipment that is closer will be dispatched first to ensure the timeliness of the fire extinguishing effect.

[0196] Each fire-fighting equipment (such as high-pressure sprinkler, fire blanket, etc.) will be assigned a task according to the location and urgency of the fire.

[0197] The system dynamically adjusts the allocation of fire-fighting resources based on the status of the equipment (whether it is idle, whether it is moving, whether it has been dispatched to other fire sources, etc.).

[0198] Path planning algorithm: Each fire-fighting device calculates the shortest path or optimal path based on the location of the target fire source to ensure that the device can quickly and accurately reach the fire source and start extinguishing the fire. Dijkstra algorithm is often used to calculate the shortest path. The system can also use methods such as reinforcement learning to optimize path planning so that the device can dynamically adapt to changes in different fire sources.

[0199] Device collaborative work: If multiple devices are dispatched to the same fire source, the system needs to avoid conflicts and resource waste between devices. By coordinating the work between devices, the system ensures that each device can play its full role and avoids duplicate fire extinguishing or resource waste.

[0200] Virtual coordination: Through virtual device coordination and time allocation, ensure that the working time and space of each device are effectively allocated.

[0201] Parallel work: Different devices (such as sprinklers, fire blankets, etc.) can simultaneously perform fire extinguishing tasks for different fire sources, improving the overall fire extinguishing efficiency.

[0202] To ensure the efficient operation of the system, the status of each fire extinguishing device must be monitored in real time. The status feedback of the device is crucial for dynamic allocation.

[0203] Each fire extinguishing device is equipped with a position sensor and a working status sensor (such as whether the sprinkler is activated, whether the fire extinguishing liquid is sprayed normally, etc.). These sensors real-time feedback the status data of the device (such as the current position, working status, remaining power, etc.) to the central control system.

[0204] Real-time data update: The status data of the device is transmitted to the control system, and the system dynamically adjusts the task allocation of the device according to these data to ensure that each device can effectively execute the task.

[0205] When a device completes a task, the system immediately updates its status to "idle" and re-evaluates the priority of the current fire source, and may dispatch the device to other fire sources for support.

[0206] Load balancing: If the fire extinguishing work at a certain fire source progresses slowly, the system can re-adjust the task allocation according to the device status, prevent a certain fire source from not being processed for a long time, and ensure that multiple fire sources are processed in a timely manner.

[0207] In a complex fire scenario, the position and status of the fire source change over time. The system needs to have the ability of dynamic response and adapt to the changes of the fire in real time.

[0208] Real-time monitoring: The system continuously obtains the status information of the fire source and the device from sensors, cameras, temperature sensors, etc. Based on these data, the control system will real-time update the status of the fire source and the availability of the device to ensure that the scheduling strategy can be adjusted at any time.

[0209] Fire source change tracking: If some fire sources change due to environmental factors (such as wind direction change, fire source expansion, etc.), the system can real-time update the coordinates of the fire source and recalculate the path and scheduling strategy.

[0210] The system can perform multi-objective optimization based on the multi-dimensional information of the fire source and equipment (such as temperature, distance, fire spread speed, working status of fire extinguishing equipment, etc.). Using the multi-objective optimization algorithm, the system can find a balance between multiple objectives (such as the shortest fire extinguishing time, the least resource waste, etc.).
