Description

Technical Field

[0001] The present application relates to the field of vehicle spontaneous combustion identification and warning, and in particular to a vehicle spontaneous combustion identification and warning method and system. Background Art

[0002] With the increase of urban population and the rapid growth of car ownership, the demand for underground parking lots in residential areas and office buildings is increasing. However, due to the relatively closed and densely populated underground spaces, the risk of fire is also increasing. The number of spontaneous combustion of vehicles in underground garages is also increasing. If not handled in time, it may lead to serious consequences.

[0003] Traditional fire warning technologies, which rely on smoke detectors or security personnel to monitor in real time via surveillance video, have certain limitations in underground parking environments. Due to the large number of interference factors such as vehicle exhaust and dust in underground parking lots, smoke detectors are prone to false alarms or missed alarms. In addition, by the time the smoke sensor detects smoke, the fire has already spread rapidly, making it impossible to extinguish the fire in time. Summary of the invention

[0031] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0032] The embodiment of the present application provides a vehicle spontaneous combustion identification and warning method, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and the embodiment of the present application does not limit this. Figure 1 As shown, the method includes step S101, step S102, step S103, step S104, step S105 and step S106, wherein: S101, acquiring surveillance images and infrared images at multiple locations in the parking lot.

[0033] For the embodiments of the present application, in order to monitor the parking situation, personnel situation and accidents in the parking lot, camera devices are installed in multiple positions of the parking lot. The camera devices are used to collect images of the vehicle appearance and the surrounding environment. The camera devices are connected to electronic devices by wire. The electronic devices obtain monitoring images and infrared images of multiple positions in the parking lot. The infrared images can clearly show the pixel changes in the parking lot.

[0034] S102, performing flame recognition on the infrared image after preprocessing to obtain a recognition result.

[0035] In the embodiment of the present application, the electronic device performs flame recognition on the infrared image after graying, filtering, enhancing, etc., to obtain a recognition result.

[0036] S103, judging whether there is a spontaneously combusting vehicle based on the recognition result.

[0037] Among them, a spontaneous combustion vehicle is a vehicle that produces flames.

[0038] For the embodiment of the present application, specific algorithms and models are stored in the electronic device for identifying flame characteristics. During the identification process, each pixel or area in the image is analyzed to determine whether it has the characteristics of a flame. Based on the identification results, it can be determined whether there is a self-igniting vehicle that produces flames.

[0039] S104: If yes, determine the flame range based on the infrared image.

[0040] For the embodiment of the present application, if any, the electronic device determines the flame range based on the infrared image, and the size of the flame range reflects the size of the fire and the size of the possible impact.

[0041] S105, determining a target fire sprinkler head from all fire sprinkler heads based on the monitoring image and the flame range.

[0042] For the embodiment of the present application, in order to respond to sudden fire situations in the parking lot in a timely manner, fire-fighting equipment is installed in the parking lot, but the positions of the fire sprinklers are randomly distributed corresponding to each parking space. Therefore, the electronic device determines the target fire sprinkler from all the fire sprinklers based on the monitoring image and the flame range. The target fire sprinkler can extinguish the fire of the spontaneously combusting vehicle more quickly and accurately.

[0043] S106, controlling the target fire sprinkler to open.

[0044] In the embodiment of the present application, all fire sprinklers are wired to the electronic device, and the electronic device controls the target fire sprinkler to open, so as to timely and accurately extinguish the flame of the spontaneous combustion vehicle, prevent the fire from spreading, and reduce unnecessary losses. The flame is identified based on the monitoring images and infrared images in the parking lot, the flame range is determined, and the target fire sprinkler is determined from all the fire sprinklers based on the monitoring images and the flame range, and then the target fire sprinkler is controlled to open, so that the flame of the spontaneous combustion vehicle can be extinguished in time, the fire is prevented from spreading, and unnecessary losses are reduced.

[0045] In a possible implementation of the embodiment of the present application, flame recognition is performed after preprocessing the infrared image in step S102 to obtain a recognition result, which specifically includes step S1021 (not shown in the figure), step S1022 (not shown in the figure), step S1023 (not shown in the figure) and step S1024 (not shown in the figure), wherein: Step S1021, performing grayscale transformation on the infrared image to obtain a grayscale image, and determining each pixel point and its neighboring pixels in the grayscale image.

[0046] For the embodiment of the present application, the electronic device converts the infrared image into a grayscale image, and determines each pixel point and its neighboring pixels in the grayscale image. Because the infrared image contains a large amount of information, the computational complexity will increase, and the main features of the flame, such as brightness, can also be effectively reflected in the grayscale image. For example, in the RGB color space, the color pixel values ​​in the infrared image are converted into grayscale values ​​through a specific weighted average algorithm, and the formula can be Y=0.299R+0.587G+0.114B, where Y is the grayscale value of each pixel point, and R, G, and B are the red, green, and blue brightness values ​​of each pixel point, respectively.

[0047] Step S1022, denoising the grayscale image based on each pixel and its neighboring pixels to obtain a denoised grayscale image.

[0048] For the embodiment of the present application, the electronic device performs denoising on the grayscale image based on each pixel and its neighboring pixels to obtain a denoised grayscale image. The denoised grayscale image can more accurately extract the true characteristics of the flame.

[0049] Step S1023, performing enhancement processing on the denoised grayscale image to obtain an enhanced grayscale image.

[0050] For the embodiment of the present application, the electronic device performs enhancement processing on the denoised grayscale image to obtain an enhanced grayscale image, and can enhance the contrast of the image through methods such as histogram equalization to make the difference between the flame area and the background more obvious.

[0051] Step S1024, inputting the enhanced grayscale image into the trained network model for flame recognition to obtain a recognition result.

[0052] For the embodiment of the present application, the electronic device inputs the enhanced grayscale image into a trained network model for flame recognition to obtain a recognition result, wherein the network model may be a convolutional neural network model, which extracts local features of the image through a convolutional layer, reduces data dimensions through a pooling layer, and performs classification through a fully connected layer. The convolutional neural network model is a model that has been trained with a large number of flame and non-flame images and can automatically learn the complex features of flames.

[0053] In a possible implementation of the embodiment of the present application, in step S105, a target fire sprinkler is determined from all fire sprinklers based on the monitoring image and the flame range, specifically including step S1051 (not shown in the figure), step S1052 (not shown in the figure), step S1053 (not shown in the figure) and step S1054 (not shown in the figure), wherein: Step S1051, determining a first distance between each fire sprinkler and each vertex of the parking space where the spontaneously ignited vehicle is located.

[0054] For the embodiment of the present application, the fire sprinklers in the parking lot are randomly distributed and the distances between each parking space are inconsistent. Therefore, the electronic device determines the first distance between each fire sprinkler and each vertex of the parking space where the spontaneously ignited vehicle is located based on the monitoring image.

[0055] Step S1052: determine the candidate fire sprinkler with the shortest distance to each vertex based on the first distance.

[0056] For the embodiment of the present application, there are many fire sprinklers in the parking lot. In order to accurately extinguish the spontaneously combusting vehicle, it is necessary to determine the fire sprinklers that are closer to the spontaneously combusting vehicle. Therefore, the electronic device determines the candidate fire sprinklers with the shortest distance to each vertex based on the first distance.

[0057] Step S1053: if there is no identical fire sprinkler head among the fire sprinkler heads corresponding to all vertices, the fire sprinkler head with the smallest distance between each vertex is determined as the target fire sprinkler head.

[0058] For the embodiment of the present application, if there are no identical candidate fire sprinklers among the candidate fire sprinklers corresponding to all vertices, the electronic device will determine the candidate fire sprinkler with the smallest distance to each vertex as the target fire sprinkler, that is, the four candidate fire sprinklers closest to the four vertices of the parking space are the target fire sprinklers.

[0059] Step S1054: if there is at least one identical fire sprinkler head among the fire sprinklers corresponding to all vertices, at least one target area is determined according to a first preset range with each identical fire sprinkler head as the center, and the fire sprinklers in each target area and the fire sprinklers corresponding to each vertex are determined as target fire sprinklers.

[0060] For the embodiment of the present application, if there is at least one identical fire sprinkler head to be selected among the fire sprinklers corresponding to all the vertices, it means that the distance between the fire sprinklers is too far, and there may be 3, 2 or 1 fire sprinklers to be selected corresponding to the 4 vertices, and the amount of water sprayed may not be enough to cope with the fire extinguishing of the spontaneous combustion vehicle. Then the electronic device determines at least one target area according to the first preset range with each identical fire sprinkler head to be selected as the center, and determines the fire sprinklers in each target area together with the fire sprinklers corresponding to each vertex as the target fire sprinkler. For example, there are 2 identical fire sprinklers to be selected among the fire sprinklers corresponding to all the vertices, that is, there are 2 fire sprinklers to be selected corresponding to the 4 vertices, and 2 target areas are determined according to the first preset range with these 2 fire sprinklers to be selected as the center. There are another 2 fire sprinklers in the 2 target areas. Finally, the 2 fire sprinklers to be selected corresponding to the 4 vertices and the 2 fire sprinklers in the target area are determined as the final target fire sprinklers.

[0061] In a possible implementation manner of the embodiment of the present application, the method further includes step S1 (not shown in the figure), step S2 (not shown in the figure) and step S3 (not shown in the figure), wherein: Step S1, performing license plate color recognition on the monitoring image to determine the type of the spontaneously ignited vehicle, which includes a fuel vehicle with a blue license plate and a new energy vehicle with a green license plate.

[0062] For the embodiment of the present application, the underground parking lots of residential areas or office buildings are mostly fuel vehicles with blue license plates and new energy vehicles with green license plates. The electronic equipment inputs the monitoring image into the trained network model to perform license plate color recognition, determine the license plate color of the spontaneously combusting vehicle, and then determine the type of the spontaneously combusting vehicle. Different vehicle types are prone to different ignition points, so determining the vehicle type is conducive to the subsequent targeted fire extinguishing treatment of the flame.

[0063] Step S2, if the spontaneously igniting vehicle is a fuel vehicle, determine the positions of adjacent vehicles, each position corresponds to a preset parking space edge, determine the first fire nozzle for extinguishing fire from the target fire nozzles, and the second fire nozzle for spraying water to the preset parking space edge corresponding to the position of the adjacent vehicle, control the first fire nozzle to spray to the engine area of ​​the spontaneously igniting vehicle, and control the second fire nozzle to spray to the preset parking space edge corresponding to the position of the adjacent vehicle.

[0064] For the embodiment of the present application, if the fire of the spontaneously combusting vehicle is too large, it may spread to the surrounding vehicles. If the spontaneously combusting vehicle is a fuel vehicle, the electronic device determines the position of the adjacent vehicles. Each position corresponds to a preset parking space edge, that is, the interval between the parking positions of the two vehicles. In addition, under normal circumstances, the ignition point of a fuel vehicle is prone to occur in the engine part, that is, the engine area of ​​the front of the vehicle. Therefore, the electronic device determines a first fire sprinkler for extinguishing the fire from the target fire sprinklers, and a second fire sprinkler for spraying water to the preset parking space edge corresponding to the position of the adjacent vehicle, and controls the first fire sprinkler to spray to the engine area of ​​the spontaneously combusting vehicle, and controls the second fire sprinkler to spray to the preset parking space edge corresponding to the position of the adjacent vehicle. One part is used for extinguishing the fire, and the other part is used to prevent the spread of the fire, thereby reducing damage to surrounding vehicles.

[0065] Among them, the shape of water sprayed from the first fire sprinkler and the second fire sprinkler can be changed. The first fire sprinkler used for fire extinguishing can be a water column type, which is directly sprayed to the engine area for fire extinguishing, while the second fire sprinkler used to prevent the fire from spreading to surrounding vehicles can be a fan-shaped water curtain in the form of a surface, which can extinguish the flames spreading outward when passing through the water curtain.

[0066] Step S3, if the spontaneously igniting vehicle is a new energy vehicle, the positions of adjacent vehicles are determined, each position corresponds to a preset parking space edge, and a first fire sprinkler for extinguishing fires and a second fire sprinkler for spraying water to the preset parking space edge corresponding to the position of the adjacent vehicle are determined from the target fire sprinklers. The first fire sprinkler is controlled to spray to the preset position around the spontaneously igniting vehicle, which is the ground on both sides of the spontaneously igniting vehicle, so that the water sprayed from the first fire sprinkler contacts the preset position and then rebounds to the battery area of ​​the spontaneously igniting vehicle, and the second fire sprinkler is controlled to spray to the preset parking space edge corresponding to the position of the adjacent vehicle.

[0067] For the embodiment of the present application, if the fire of the spontaneously combusting vehicle is too large, it may spread to the surrounding vehicles. If the spontaneously combusting vehicle is a new energy vehicle, the electronic device determines the position of the adjacent vehicles, and each position corresponds to a preset parking space edge, that is, the interval between the parking positions of the two vehicles. In addition, under normal circumstances, the fire points of new energy vehicles are mainly concentrated at the battery, that is, the battery area under the bottom of the vehicle body. The electronic device determines the first fire sprinkler for extinguishing the fire and the second fire sprinkler for spraying water to the preset parking space edge corresponding to the position of the adjacent vehicle from the target fire sprinkler. The first fire sprinkler is controlled to spray to the preset position around the spontaneously combusting vehicle. The water sprayed from the fire sprinkler from the top cannot be sprayed directly to the spontaneously combusting flame no matter how the angle is adjusted. Therefore, the preset position is the ground on both sides of the spontaneously combusting vehicle, so that the water sprayed from the first fire sprinkler contacts the preset position and rebounds to the battery area of ​​the spontaneously combusting vehicle, and the second fire sprinkler is controlled to spray to the preset parking space edge corresponding to the position of the adjacent vehicle.

[0068] Among them, the shape of water sprayed from the first fire sprinkler and the second fire sprinkler can be changed. The first fire sprinkler used for extinguishing fire can be a water column type, which can rebound to the spontaneous combustion flame after spraying to a preset position. The second fire sprinkler used to prevent the fire from spreading to surrounding vehicles can be a fan-shaped water curtain in the form of a surface.

[0069] A possible implementation of the embodiment of the present application, in step S2 and step S3, a first fire sprinkler head for extinguishing fire and a second fire sprinkler head for spraying water to the edge of a preset parking space corresponding to the position of an adjacent vehicle are determined from the target fire sprinkler heads, specifically including step S4 (not shown in the figure) and step S5 (not shown in the figure), wherein: Step S4, if the spontaneous combustion vehicle is a new energy vehicle, determine the second distance between each target fire sprinkler and the preset position, determine the target fire sprinkler with the shortest distance to the preset position as the first fire sprinkler, and determine the remaining target fire sprinkler as the second fire sprinkler.

[0070] For the embodiments of the present application, the positions of the target fire sprinklers are different, and the positions of the ignition points are different for different vehicle types. Therefore, if the spontaneously combusting vehicle is a new energy vehicle, the electronic device determines the second distance between each target fire sprinkler and the preset position, and determines the target fire sprinkler with the shortest distance to the preset position as the first fire sprinkler, and determines the remaining target fire sprinklers as the second fire sprinkler. There can be two preset positions, which are on the ground on the left and right sides of the vehicle, that is, the two first fire sprinklers closest to the preset positions are used for fire extinguishing, and spray toward the preset positions and rebound to the battery at the bottom of the vehicle body.

[0071] Step S5, if the spontaneously igniting vehicle is a fuel vehicle, the electronic device determines the third distance between each target fire sprinkler and the center point of the edge of the preset parking space, and determines the target fire sprinkler with the shortest distance to the center point of the edge of the preset parking space as the second fire sprinkler, and determines the remaining target fire sprinkler as the first fire sprinkler.

[0072] For the embodiment of the present application, if the spontaneously ignited vehicle is a fuel vehicle, the electronic device determines the third distance between each target fire sprinkler and the center point of the edge of the preset parking space, and determines the target fire sprinkler with the smallest distance to the center point of the edge of the preset parking space as the second fire sprinkler for spraying water to prevent the fire from spreading to surrounding vehicles, and determines the remaining target fire sprinklers as the first fire sprinkler for spraying water at the flame to extinguish the fire.

[0073] In a possible implementation manner of the embodiment of the present application, the method further includes step 1, wherein: Step 1: If there is a vehicle that has caught fire, an alarm message is output and the broadcast in the parking lot is turned on.

[0074] For the embodiment of the present application, if there is a vehicle that spontaneously ignites, the electronic device will send an alarm message to relevant personnel, such as notifying the parking lot manager, security personnel, and fire department through text messages, APP push, etc., and turning on the broadcast in the parking lot. When there are people in the parking lot, they can shout and drive them away remotely to prevent secondary accidents.

[0075] In a possible implementation manner of the embodiment of the present application, the method further includes step 2, step 3, step 4 and step 5, wherein: Step 2: Determine whether there is a target vehicle within the second preset range of the spontaneous combustion vehicle based on the monitoring image. The target vehicle is a vehicle that may be spread by the spontaneous combustion vehicle.

[0076] For the embodiment of the present application, when a vehicle catches fire spontaneously, the fire may spread to the fuel tank or battery due to the large size, which may easily cause an explosion and cause the fire to spread to a larger area. Therefore, the electronic device determines based on the monitoring image whether there is a target vehicle within the second preset range of the spontaneously combusting vehicle that may be spread to by the spontaneously combusting vehicle.

[0077] Step three: if it exists, determine the target position of the target vehicle, and determine the vacant parking space outside the second preset range based on the monitoring image.

[0078] For the embodiment of the present application, if it exists, the electronic device determines the target position of the target vehicle and needs to move the target vehicle as soon as possible to avoid causing damage to the target vehicle. Therefore, the electronic device also needs to determine the vacant parking spaces outside the second preset range based on the monitoring image, so that the target vehicle will not stay in the aisle after being moved away to affect the parking of other vehicles or fire fighting.

[0079] Step 4: Determine the moving route of the target vehicle based on the target position and the position of the vacant parking space.

[0080] For the embodiment of the present application, the electronic device determines multiple routes based on the target location and the location of the vacant parking spaces, and determines the shortest route as the moving route of the target vehicle, which can move the target vehicle out and away from the spontaneously combusting vehicle more quickly.

[0081] Step 5: Control the vehicle moving robot to move the target vehicle according to the moving route.

[0082] For the embodiment of the present application, the car moving robot can control the tires of the vehicle to move, so the electronic device controls the car moving robot to move the target vehicle according to the moving route to avoid being affected by the fire of the spontaneously combusting vehicle.
