[0065] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0066] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0067] In this embodiment, for ease of description, the following description will focus on fire detection equipment configured on vehicles equipped with smoke sensors, temperature sensors, cameras, and charging unlocking modules, or on terminals such as mobile terminals, data storage control terminals, and PCs connected to electronic control units that are associated with fire detection equipment.

[0068] Based on the aforementioned fire detection equipment, the overall concept of the fire avoidance method of this application is proposed.

[0069] With the continuous development of the automotive industry, new energy vehicles have become the preferred mode of transportation for more and more users' daily travel. In particular, new energy vehicles are prone to spontaneous combustion during charging or after being left stagnant in high-temperature environments for extended periods. Spontaneous combustion in a new energy vehicle can spread to nearby parked vehicles, causing significant economic losses. In related technologies, technicians typically install fire detection systems in vehicles to determine if combustion is occurring inside the vehicle and then initiate fire suppression procedures when confirmed. However, this method only allows the vehicle to detect its own combustion. Thus, if other vehicles nearby spontaneously combust, the new energy vehicle itself remains vulnerable to the spread, significantly increasing its own risk of ignition.

[0070] To address the above phenomena, this application provides a fire avoidance method applied to a vehicle, comprising: acquiring combustion characteristic parameters, wherein the combustion characteristic parameters include real-time temperature parameters and / or real-time smoke concentration parameters; when the combustion characteristic parameters are detected to reach a matching first parameter threshold, capturing a target image; extracting image features from the target image, and determining whether a burning vehicle exists in the target image based on the image features; and, if a burning vehicle is determined to exist in the target image, determining a target escape route, and controlling the vehicle to move away from the burning vehicle according to the target escape route.

[0071] This application, by detecting the environment in which the vehicle is located, can promptly identify other vehicles in the environment when abnormal real-time temperature and / or real-time smoke concentration are detected. If a burning vehicle is detected in the surrounding environment, a target escape route can be planned to move away from the burning vehicle, thereby avoiding the situation where the vehicle is ignited by the burning vehicle and achieving the technical effect of reducing the risk of vehicle ignition.

[0072] Based on the overall concept of the fire avoidance method of this application, the embodiments of this application provide a fire avoidance method. Referring to Figure 1, Figure 1 is a flowchart of the first embodiment of the fire avoidance method of this application.

[0073] In this embodiment, the fire avoidance method is applied to a vehicle, and the fire avoidance method includes steps S10 to S40:

[0074] Step S10: Obtain combustion characteristic parameters, wherein the combustion characteristic parameters include real-time temperature parameters and / or real-time smoke concentration parameters;

[0075] It should be noted that the vehicle is equipped with an environmental detection module, which may specifically include a smoke detection unit and a temperature detection unit, both of which can be mounted on the vehicle's exterior. Furthermore, the combustion characteristic parameters refer to environmental parameters within the vehicle's surrounding environment, specifically including real-time smoke concentration parameters and / or real-time temperature parameters. The real-time smoke concentration parameter S represents the smoke concentration within the vehicle's surrounding environment per unit time t0; similarly, the real-time temperature parameter T represents the temperature within the vehicle's surrounding environment per unit time t0.

[0076] In this embodiment, during operation, the fire detection equipment first controls the environmental detection module installed on the vehicle, thereby collecting combustion characteristic parameters such as real-time temperature parameters and / or real-time smoke concentration parameters generated by the environment around the vehicle through the environmental detection module.

[0077] For example, when the fire detection equipment is in operation, it first controls the smoke sensor configured on the vehicle to collect the real-time smoke concentration parameter S generated in the environment around the vehicle; and / or, the fire detection equipment may also control the temperature sensor configured on the vehicle to collect the real-time temperature parameter T generated in the environment around the vehicle.

[0078] In this way, fire detection equipment can constantly monitor the environment around the vehicle to obtain combustion characteristic parameters of the surrounding environment, so as to determine in a timely manner whether there is a burning vehicle around the vehicle based on the combustion characteristic parameters.

[0079] Step S20: If the combustion feature parameters are detected to reach the matching first parameter threshold, acquire the target image;

[0080] It should be noted that the first parameter threshold is an environmental parameter used to determine the probability of a burning vehicle existing around the vehicle. Specifically, this first parameter threshold may include a first temperature parameter threshold, a first temperature change threshold, and a first smoke concentration threshold. That is, when the real-time temperature parameter reaches the first temperature parameter threshold, and / or the real-time smoke concentration parameter reaches the first smoke concentration threshold, and / or the temperature change parameter reaches the first temperature change threshold, it indicates a high probability of a burning vehicle existing around the vehicle. Furthermore, the target image is image data containing target vehicles adjacent to the vehicle.

[0081] In this embodiment, after acquiring each combustion characteristic parameter, the fire detection device further reads its own configured storage module to obtain a preset first parameter threshold that matches the combustion characteristic parameter. The fire detection device then compares the combustion characteristic parameter with the first parameter threshold, and when it detects that the combustion characteristic parameter has reached the first parameter threshold, it controls the image acquisition module configured on the vehicle to capture image data of the target vehicle adjacent to the vehicle through the image acquisition module.

[0082] For example, please refer to Figure 2, which is a schematic diagram of the target image involved in an embodiment of the fire avoidance method of this application. After acquiring the real-time smoke concentration parameter S and the real-time temperature parameter T, the fire detection device reads its configured storage module to obtain a first smoke concentration threshold S0 that matches the real-time smoke concentration parameter S. The fire detection device then compares the real-time smoke concentration parameter S and the first smoke concentration threshold S0 to obtain a first comparison result. At the same time, the fire detection device calculates the temperature change parameter ΔT corresponding to the vehicle based on the real-time temperature parameter T. The fire detection device then reads the storage module to obtain the temperature change parameter ΔT that matches the real-time smoke concentration parameter S0. The fire detection device compares the temperature change parameter ΔT with the first temperature change threshold ΔT0 to obtain a second comparison result. When the fire detection device reads that the real-time smoke concentration parameter S reaches the first smoke concentration threshold S0, and / or when the fire detection device reads that the temperature change parameter ΔT reaches the first temperature change threshold ΔT0, it determines that there may be a burning vehicle around the vehicle, and then controls the camera configured on the vehicle to capture a target image containing the target vehicle adjacent to the vehicle, as shown in Figure 2.

[0083] In this way, the fire detection equipment can promptly determine whether there is a burning vehicle around the vehicle based on the combustion characteristic parameters. If it determines that there may be a burning vehicle around the vehicle, it calls the image acquisition module configured on the vehicle to capture a target image containing adjacent vehicles in order to determine whether the target vehicle is a burning vehicle.

[0084] Step S30: Extract the image features of the target image, and determine whether there is a burning vehicle in the target image based on the image features;

[0085] In this embodiment, after acquiring the target image, the fire detection device extracts the image features of the target image, and then identifies the target vehicle contained in the target image based on the image features to determine whether there is a burning vehicle in the target image.

[0086] For example, after acquiring a target image, the fire detection device extracts the image features contained in the target image. The fire detection device then determines the vehicle outline, local image brightness difference, image brightness parameters, image color features, and other burning vehicle identification parameters of the target vehicle based on the image features. The fire detection device then determines whether the target vehicle in the image data is a burning vehicle based on the burning vehicle identification.

[0087] In this way, the fire detection equipment can identify the acquired target image to determine whether the target vehicle contained in the target image is a burning vehicle.

[0088] In one feasible implementation, the step of "determining whether a burning vehicle exists in the target image based on the image features" in step S30 above may specifically include at least one of steps S301 to S304:

[0089] Step S301: Determine the vehicle outline corresponding to the target vehicle contained in the target image based on the image features, and determine the presence of a burning vehicle in the target image if the vehicle outline is detected to be in a state of missing lines.

[0090] Step S302: Determine the local image brightness difference corresponding to the target vehicle based on the image features, and if the local image brightness difference reaches a preset brightness difference threshold, determine that there is a burning vehicle in the target image;

[0091] Step S303: Determine the area of ​​the bright image corresponding to the target vehicle based on the image features, and if the area of ​​the bright image reaches a preset image area threshold, determine that there is a burning vehicle in the target image;

[0092] Step S304: Determine the local image color features corresponding to the target vehicle based on the image features, and if the local image color features match the preset combustion color features, determine that there is a burning vehicle in the target image.

[0093] In this embodiment, after the fire detection device extracts the image features of the target image, it determines the vehicle outline of the target vehicle contained in the target image based on the image features. The fire detection device then identifies the vehicle outline, and thus determines that there is a burning vehicle in the target image when the vehicle outline is in a state of missing lines.

[0094] After acquiring image features, the fire detection equipment can also determine the first image brightness parameter corresponding to the area where the target vehicle is located based on the image features. At the same time, the fire detection equipment determines the second image brightness parameter corresponding to the scene around the target vehicle based on the image features. The fire detection equipment processes the first image brightness parameter and the second image brightness parameter to obtain the local image brightness difference value corresponding to the target vehicle. The fire detection equipment reads the aforementioned storage module to obtain a preset brightness difference threshold value. When it detects that the local image brightness difference value reaches the brightness difference threshold value, it determines that there is a burning vehicle in the target image.

[0095] After acquiring image features, the fire detection equipment can also identify the first image brightness parameter corresponding to the area where the target vehicle is located, and read the brightness parameter threshold corresponding to the first image brightness parameter. The fire detection equipment compares the first image brightness parameter with the brightness parameter threshold, and determines the bright image area corresponding to the first brightness parameter when it is determined that the first image brightness parameter reaches the brightness parameter threshold. At the same time, the fire detection equipment reads the storage module to obtain the preset image area threshold, and determines that there is a burning vehicle in the target image when the detected bright image area reaches the image area threshold.

[0096] After acquiring image features, the fire detection equipment can also determine the local image color corresponding to the area where the target vehicle is located based on the image features. The fire detection equipment then reads the storage module to obtain multiple preset burning image colors used to indicate vehicle combustion. The fire detection equipment compares the local image color with the multiple burning image colors respectively. If it is determined that there is a target burning image color that matches the local image color among the multiple burning image colors, it is determined that there is a burning vehicle in the target image.

[0097] For example, after acquiring image features, the fire detection device first determines the vehicle outline of the target vehicle contained in the target image based on the image features. The fire detection device identifies the vehicle outline to determine whether the vehicle outline is complete. If the fire detection device determines that the vehicle outline is complete, it determines that the vehicle outline is in a complete state. Similarly, if the fire detection device determines that the vehicle outline is incomplete, it determines that the vehicle outline is in a missing state. Then, if the fire detection device detects that the vehicle outline is in a missing state, it determines that the vehicle outline is missing due to interference from flames, smoke, etc., and thus determines that there is a burning vehicle in the target image.

[0098] After acquiring image features, the fire detection equipment can determine the first image brightness parameter B1 corresponding to the area where the target vehicle is located based on the image features. At the same time, the fire detection equipment determines the second image brightness parameter B2 corresponding to other image areas around the target vehicle based on the image features. The fire detection equipment then calculates the first image brightness parameter B1 and the second image brightness parameter B2 to determine the local image brightness difference B2-B1 between the target vehicle and the surrounding environment. The fire detection equipment then reads the aforementioned storage module to obtain a preset brightness difference threshold and compares the local image brightness difference B2-B1 with the preset brightness difference threshold. If the fire detection equipment determines that the comparison result is that the local image brightness difference B2-B1 reaches the brightness difference threshold, it determines that there may be fire in the area where the target vehicle is located, and thus determines that there is a burning vehicle in the target image.

[0099] After acquiring image features, the fire detection equipment can determine the first image brightness parameter B1 corresponding to the area where the target vehicle is located based on the image features. At the same time, the fire detection equipment reads the storage module to obtain a preset brightness parameter threshold and compares the first image brightness parameter B1 with the brightness parameter threshold to obtain a comparison result. If the fire detection equipment reads that the comparison result shows that the first image brightness parameter B1 has reached the brightness parameter threshold, it further detects the bright image area corresponding to the first image brightness parameter B1 and obtains a preset image area threshold. The fire detection equipment compares the bright image area with the image area threshold. Thus, if it is determined that the bright image area has reached the image area threshold, it is determined that there may be fire in the area where the target vehicle is located, and thus it is determined that there is a burning vehicle in the target image.

[0100] After acquiring image features, the fire detection equipment can determine the local image color (RGB) of the area where the target vehicle is located based on the image features. At the same time, the fire detection equipment reads the storage module to obtain multiple preset burning image colors such as red, golden yellow, gray, and black, which are used to indicate vehicle combustion. The fire detection equipment then determines the image color area corresponding to the local image color (RGB). If the detected image color area reaches a preset color area threshold, the local image color (RGB) is compared with the multiple burning image colors. If the fire detection equipment determines that the local image color (RGB) matches the target burning image color among the multiple burning image colors, it determines that there may be flames or smoke in the area where the target vehicle is located, and thus determines that there is a burning vehicle in the target image.

[0101] In addition, in this embodiment and another embodiment, after the fire detection equipment determines that the target vehicle is a burning vehicle, it can first call the camera to take pictures of the surrounding environment to generate fire information, and send the fire information to the mobile terminal device used by the driver to issue a reminder to the driver.

[0102] In this way, the fire detection equipment can identify the acquired target image to determine whether the target vehicle contained in the target image is a burning vehicle.

[0103] Step S40: If it is determined that there is a burning vehicle in the target image, determine the target escape route and control the vehicle to move away from the burning vehicle according to the target escape route.

[0104] In this embodiment, after the fire detection equipment determines the burning vehicle in the target image, it further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the burning vehicle.

[0105] In this way, fire detection equipment can automatically drive away from the burning vehicle by following a pre-planned route, thereby reducing the risk of the vehicle itself being ignited.

[0106] In one feasible implementation, the step of "determining the target escape route" in step S40 above may specifically include steps S401 to S403:

[0107] Step S401: Obtain the parking route corresponding to the vehicle and obtain the preset vehicle departure distance;

[0108] Step S402: Determine each parking space to be screened on the parking route, and screen each parking space to be screened according to the vehicle departure distance to determine the target parking space;

[0109] Step S403: Generate a target departure route based on the target and the parking route.

[0110] In this embodiment, after the fire detection device determines that the burning vehicle is contained in the target image, it first reads the aforementioned storage module to obtain the parking route generated by the vehicle before entering the parking space and the preset vehicle departure distance. Then, the fire detection device determines each parking space to be screened on the parking route and screens each parking space to be screened according to the vehicle departure distance to determine the target parking space that is outside the vehicle departure distance and located on the vehicle parking route. Finally, the fire detection device generates a target departure route based on the target parking space and the parking route.

[0111] For example, after determining that the target image contains a burning vehicle, the fire detection device first reads the aforementioned storage module to obtain the parking route generated by the vehicle before entering the parking space and the preset vehicle departure distance D. Then, the fire detection device calls the aforementioned camera to identify the parking route to determine each unused parking space to be screened on the parking route. The fire detection device then screens each unused parking space to be screened based on the vehicle departure distance D, thereby determining the target parking space that is on the parking route and is more than D away from the current parking space. Finally, the fire detection device plans the target departure route based on the target parking space and the parking route.

[0112] In this way, fire detection equipment can automatically drive away from the burning vehicle by following a pre-planned route, thereby reducing the risk of the vehicle itself being ignited.

[0113] It should be noted that, in this embodiment and another embodiment, after extracting image features, the fire detection equipment can also identify other fire sources such as burning houses and equipment in the image based on parameters such as the outlines of various objects, local image brightness differences, bright image areas, and local color features contained in the image features. Upon detecting a fire source, the equipment can control the vehicle to move away from the fire source along a target escape route. It is understood that this application does not limit the specific type of fire source.

[0114] In this embodiment, during operation, the fire detection device first controls the environmental detection module configured on the vehicle to collect real-time temperature parameters and / or real-time smoke concentration parameters and other combustion characteristic parameters generated by the environment around the vehicle. Then, the fire detection device reads its own configured storage module to obtain a preset first parameter threshold that matches the combustion characteristic parameters. The fire detection device then compares the combustion characteristic parameters with the first parameter threshold. If the combustion characteristic parameters are detected to have reached the first parameter threshold, the device controls the image acquisition module configured on the vehicle to capture image data of target vehicles adjacent to the vehicle. Next, the fire detection device extracts the image features of the target image and then identifies the target vehicles contained in the target image based on the image features to determine whether there is a burning vehicle in the target image. Finally, after determining that there is a burning vehicle in the target image, the fire detection device further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the burning vehicle.

[0115] Thus, this application solves the technical problem of the high risk of vehicle ignition in related technologies. That is, by detecting the environment in which the vehicle is located, this application can identify other vehicles in the environment in a timely manner when abnormal real-time temperature and / or real-time smoke concentration are detected. When a burning vehicle is detected in the surrounding environment, a target escape route is planned to move away from the burning vehicle, thereby avoiding the situation where the vehicle is ignited by the burning vehicle and achieving the technical effect of reducing the risk of vehicle ignition.

[0116] Based on the first embodiment of this application, a second embodiment of this application is proposed herein. In this second embodiment, content that is the same as or similar to the above embodiments can be referred to the above description and will not be repeated hereafter. Furthermore, after step S10, the fire avoidance method of this application may further include steps A10 to A30:

[0117] Step A10: Determine the real-time temperature parameter included in the combustion characteristic parameters, and determine the second temperature parameter threshold that matches the real-time temperature parameter, wherein the second temperature parameter threshold is greater than the first temperature parameter threshold included in the first parameter threshold;

[0118] Step A20: If the real-time temperature parameter is detected to reach the second temperature parameter threshold, it is determined that there is a burning vehicle around the vehicle; Step A30: If it is determined that there is a burning vehicle around the vehicle, a target escape route is determined, and the vehicle is controlled to move away from the burning vehicle according to the target escape route.

[0119] In this embodiment, after acquiring combustion characteristic parameters, the fire detection device can not only call the image acquisition module to identify whether there is a burning vehicle around the vehicle, but also directly read the real-time temperature parameters contained in the combustion characteristic parameters and read the aforementioned storage module to obtain a second temperature parameter threshold greater than the aforementioned first temperature parameter threshold. Then, the fire detection device compares the real-time temperature parameter and the second temperature parameter threshold. Thus, if the real-time temperature parameter reaches the second temperature parameter threshold, it determines that there is a burning vehicle around the vehicle. Finally, if it determines that there is a burning vehicle around the vehicle, the fire detection device further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the aforementioned burning vehicle.

[0120] For example, if other vehicles adjacent to the vehicle spontaneously combust at a relatively high speed, causing a rapid increase in the real-time temperature of the environment surrounding the vehicle, the fire detection device, after acquiring various combustion characteristic parameters, can first read the real-time temperature parameter included in the combustion characteristic parameters, and then read the aforementioned storage module to obtain the second temperature parameter threshold T1 corresponding to the real-time temperature parameter, which is greater than the aforementioned first temperature parameter threshold T0. Afterwards, the fire detection device compares the real-time temperature parameter T with the second temperature parameter threshold T1. Thus, if the real-time temperature parameter T is detected to reach the second temperature parameter threshold T1, it determines that the temperature around the vehicle is rapidly increasing, thereby determining that there is a burning vehicle around the vehicle. Finally, if the fire detection device determines that there is a burning vehicle around the vehicle, it further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the aforementioned burning vehicle.

[0121] In this way, when neighboring vehicles around the vehicle spontaneously combust at a relatively high speed, the fire detection equipment can detect the drastic temperature changes in a short period of time, and thus control the vehicle in advance to move away from the burning vehicle along the target escape route, thereby further reducing the risk of the vehicle itself being ignited.

[0122] In one feasible implementation, after the step of "determining the real-time temperature parameter included in the combustion characteristic parameters" in step A10 above, the fire avoidance method of this application may further include steps A40 to A60:

[0123] Step A40: Determine the temperature change parameter based on the real-time temperature parameter, and determine the second temperature change threshold that matches the temperature change parameter, wherein the second temperature change threshold is greater than the first temperature change threshold included in the first parameter threshold;

[0124] Step A50: If the temperature change parameter is detected to reach the second temperature change threshold, it is determined that there is a burning vehicle around the vehicle; Step A60: If it is determined that there is a burning vehicle around the vehicle, a target escape route is determined, and the vehicle is controlled to move away from the burning vehicle according to the target escape route.

[0125] In this embodiment, after acquiring real-time temperature parameters, the fire detection device can also calculate the temperature change parameters per unit time based on each real-time temperature parameter, and read the storage module to obtain a preset second temperature change threshold that is greater than the first temperature change threshold. Then, the fire detection device compares the temperature change parameters with the second temperature change threshold. If the temperature change parameters reach the second temperature change threshold, it determines that there is a burning vehicle around the vehicle. Finally, if the fire detection device determines that there is a burning vehicle around the vehicle, it further determines the target escape route corresponding to the vehicle and controls the vehicle to drive along the target escape route to move away from the burning vehicle.

[0126] For example, if other vehicles adjacent to the vehicle spontaneously combust at a relatively high speed, causing a rapid increase in the real-time temperature of the environment surrounding the vehicle, the fire detection device, after acquiring the real-time temperature parameter T, can first determine the temperature change parameter ΔT in the environment surrounding the vehicle based on each real-time temperature parameter T, and read the aforementioned storage module to obtain a second temperature change threshold ΔT1 that matches the temperature change parameter ΔT and is greater than the aforementioned first temperature change threshold ΔT0. Then, the fire detection device compares the temperature change parameter ΔT with the second temperature change threshold ΔT1, thereby determining that the temperature around the vehicle is rapidly increasing when the temperature change parameter ΔT is detected to reach the second temperature change threshold ΔT1, and thus determining that there is a burning vehicle around the vehicle. Finally, when the fire detection device determines that there is a burning vehicle around the vehicle, it further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the aforementioned burning vehicle.

[0127] In this way, when neighboring vehicles around the vehicle spontaneously combust at a relatively high speed, the fire detection equipment can detect the drastic temperature changes in a short period of time, and thus control the vehicle in advance to move away from the burning vehicle along the target escape route, thereby further reducing the risk of the vehicle itself being ignited.

[0128] In one feasible implementation, after step S10 above, the fire avoidance method of this application may further include steps A70 to A90:

[0129] Step A70: Determine the real-time smoke concentration parameter included in the combustion characteristic parameters, and determine the second smoke concentration threshold matched by the real-time smoke concentration parameter, wherein the second smoke concentration threshold is greater than the first smoke concentration threshold included in the first parameter threshold;

[0130] Step A80: If the real-time smoke concentration parameter is detected to reach the second smoke concentration threshold, it is determined that there is a burning vehicle around the vehicle;

[0131] Step A90: If it is determined that there is a burning vehicle around the vehicle, determine the target escape route and control the vehicle to move away from the burning vehicle according to the target escape route.

[0132] In this embodiment, after acquiring combustion characteristic parameters, the fire detection device can not only call the image acquisition module to identify whether there is a burning vehicle around the vehicle, but also directly read the real-time smoke concentration parameter contained in the combustion characteristic parameters and read the aforementioned storage module to obtain a second smoke concentration threshold greater than the first smoke concentration threshold. Then, the fire detection device compares the real-time smoke concentration parameter with the second smoke concentration threshold. Thus, if the real-time smoke concentration parameter reaches the second smoke concentration threshold, it determines that there is a burning vehicle around the vehicle. Finally, if it determines that there is a burning vehicle around the vehicle, the fire detection device further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the burning vehicle.

[0133] For example, if another vehicle adjacent to the vehicle spontaneously combusts at a relatively high speed, and the smoke emitted by the burning vehicle quickly spreads to the vicinity of the vehicle, the fire detection device, after acquiring various combustion characteristic parameters, can first read the real-time smoke concentration parameter S included in the combustion characteristic parameters, and then read the aforementioned storage module to obtain a second smoke concentration threshold S1 that matches the real-time smoke concentration parameter S and is greater than the aforementioned first smoke concentration threshold S0. Subsequently, the fire detection device compares the real-time smoke concentration parameter S with the second smoke concentration threshold S1. Thus, when it detects that the real-time smoke concentration parameter S reaches the second smoke concentration threshold S1, it determines that the smoke generated by the fire has spread to the vicinity of the vehicle, thereby determining that there is a burning vehicle around the vehicle. Finally, when it determines that there is a burning vehicle around the vehicle, the fire detection device further determines the target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to move away from the aforementioned burning vehicle.

[0134] In this way, when neighboring vehicles spontaneously combust at a relatively high speed, the fire detection equipment can detect the drastic changes in smoke concentration in the surrounding environment within a short period of time, and thus control the vehicle in advance to move away from the burning vehicle along the target escape route, thereby further reducing the risk of itself being ignited.

[0135] Based on the first and / or second embodiments of this application, a third embodiment of this application is proposed herein. In this third embodiment, content that is the same as or similar to the above embodiments can be referred to the above description and will not be repeated hereafter. In addition, the vehicle further includes a charging unlocking module. After step S30 above, the fire avoidance method of this application may further include steps B10 to B20:

[0136] Step B10: If it is determined that a burning vehicle exists in the target image, detect the vehicle's status;

[0137] Step B20: If the vehicle status is detected as charging port locked, the vehicle status is switched to charging port unlocked via the charging unlock module, and the step of determining the target departure route is executed.

[0138] It should be noted that, please refer to Figure 3, which is a schematic diagram of the charging module involved in an embodiment of the fire avoidance method of this application. As shown in Figure 3, in the charging port locked state, the charging gun 12 is inserted into the charging port 13, and the charging gun locking tongue 1 inside the charging gun 12 and the charging port locking buckle 2 inside the charging port are in contact; in addition, in the charging port unlocked state, the charging gun locking tongue 1 and the charging port locking buckle 2 are separated, and the charging gun 12 is dislodged from the charging port 13.

[0139] In this embodiment, after determining that there is a burning vehicle in the target image, the fire detection device can further detect the charging port configured inside the vehicle to determine the vehicle status. Then, if the fire detection device determines that the vehicle status is a charging port locked state, it controls the charging unlocking module configured inside the vehicle to adjust the vehicle status from the charging port locked state to the charging port unlocked state, thereby determining the target escape route corresponding to the vehicle and controlling the vehicle to drive along the target escape route to move away from the burning vehicle.

[0140] For example, after the fire detection equipment identifies a burning vehicle in the target image, it further detects the charging port configured inside the vehicle to determine whether the charging port latch is in contact with the charging gun latch of the external charging pile. If the fire detection equipment detects that the charging port latch is in contact with the charging gun latch, it determines that the vehicle status is a charging port locked state. Then, the fire detection equipment controls the charging unlocking module configured inside the vehicle to eject the charging gun from the charging port, thereby switching the vehicle status from the charging port locked state to the charging port unlocked state. This allows the fire detection equipment to determine the target escape route and control the vehicle to travel along the target escape route to move away from the burning vehicle.

[0141] In this way, when the fire detection equipment detects a burning vehicle around the vehicle and the vehicle is charging, it controls the charging unlocking module to automatically eject the charging gun from the charging pile, allowing the vehicle to quickly leave the charging pile and automatically drive away from the burning vehicle according to the planned departure route, further reducing the risk of the vehicle being ignited.

[0142] In one feasible implementation, the charging unlocking module includes a latch unlocking mechanism and a charging gun insulation ejection mechanism; the step of "switching the vehicle state to the charging port unlocked state through the charging unlocking module" in step B20 above may specifically include steps B201 to B202:

[0143] Step B201: Adjust the vehicle's charging port and charging gun to separate using the locking tongue unlocking mechanism;

[0144] Step B202: The charging gun is pushed out of the charging port by the charging gun insulation ejection mechanism, so that the vehicle status is switched to the charging port unlocked state.

[0145] In this embodiment, when the fire detection device detects that the vehicle is in a charging port locked state, it first controls the locking mechanism of the locking tongue in the charging unlocking module to adjust the charging gun locking tongue and the charging port latch to disengage, thereby separating the charging port and the charging gun. Then, the fire detection device controls the charging gun insulation ejection mechanism in the charging unlocking module to eject the charging gun connected to the charging port, thereby switching the vehicle state to the charging port unlocked state.

[0146] For example, when the fire detection equipment detects that the vehicle is in a charging port locked state, it first controls the charging unlocking module configured in the charging port to activate the locking tongue unlocking mechanism included in the charging unlocking module. The locking tongue unlocking mechanism impacts the charging gun locking tongue, causing the charging gun locking tongue to separate from the charging port latch. Then, the fire detection equipment controls the charging gun insulation ejection mechanism included in the charging unlocking module to push the charging gun plug, causing the charging gun plug to disengage from the charging port, thereby switching the vehicle state to the charging port unlocked state.

[0147] In this way, when the fire detection equipment detects a burning vehicle around the vehicle and the vehicle is charging, it can control the charging unlocking module to automatically eject the charging gun from the charging pile, allowing the vehicle to quickly detach from the charging pile.

[0148] In one feasible implementation, the latch unlocking mechanism includes an unlocking motor, an unlocking lever cord, and an unlocking lever. The unlocking motor is connected to the unlocking lever via the unlocking lever cord, and the unlocking lever is connected to the charging gun latch inside the charging gun. Step B201 above may specifically include steps B2011 to B2012:

[0149] Step B1011: Control the unlocking motor to enter the running state;

[0150] Step B1012: The unlocking lever is controlled by the unlocking motor and the unlocking lever pull rope so that the unlocking lever impacts the charging gun latch, thereby separating the charging gun latch from the vehicle's charging port.

[0151] In this embodiment, when the fire detection equipment detects that the vehicle is in a charging port locked state, it first controls the charging unlocking module configured in the charging port to control the unlocking motor in the unlocking mechanism of the charging unlocking module to enter the running state. Then, during the operation, the unlocking motor drives the unlocking lever rope connected to itself, and drives the unlocking lever connected to the unlocking lever rope through the unlocking lever rope, so that the unlocking lever impacts the charging gun latch connected to the charging port latch, thereby causing the charging gun latch connected to the charging port latch to separate.

[0152] For example, please refer to Figure 4, which is a schematic diagram of the latch unlocking mechanism involved in an embodiment of the fire avoidance method of this application. When the fire detection equipment detects that the vehicle is in a charging port locked state, it first controls the charging unlocking module configured in the charging port to call the latch unlocking mechanism shown in Figure 4, thereby causing the unlocking motor 3 in the latch unlocking mechanism to run. Then, during the operation, the unlocking motor 3 drives the unlocking lever pull rope 4 connected to itself, which drives the unlocking lever 5 connected to itself, causing the unlocking lever 5 to pry based on the movement fulcrum 6 on the charging port base 9, thereby causing the end of the unlocking lever 5 to impact the charging gun latch 1, so as to separate the charging gun latch 1 from the charging port latch 2.

[0153] In this way, when the fire detection equipment detects a burning vehicle around the vehicle and the vehicle is charging, it can control the charging unlocking module to automatically eject the charging gun from the charging pile, allowing the vehicle to quickly detach from the charging pile.

[0154] In one feasible implementation, the charging gun insulation ejection mechanism includes a push plate motor, a push plate screw, and a charging gun insulation push plate. The push plate motor is connected to the push plate screw, the push plate screw is connected to the charging gun insulation push plate, and the charging gun insulation push plate is connected to the charging gun. Step B202 may specifically include steps B2021 to B2022:

[0155] Step B2021: Control the pusher motor to enter the running state;

[0156] Step B2022: The operating state and the push plate screw drive the charging gun insulating push plate to move, so as to push the charging gun out of the charging port, thereby switching the vehicle state to the charging port unlocked state.

[0157] In this embodiment, please refer to Figure 5. Figure 5 is a schematic diagram of the charging gun insulation ejection mechanism involved in an embodiment of the fire avoidance method of this application. As shown in Figure 5, after the fire detection equipment determines that the charging gun latch 1 and the charging port latch 2 are separated, it further controls the charging gun insulation ejection mechanism configured in the charging unlocking module, thereby causing the push plate motor 11 configured in the charging gun insulation ejection mechanism to enter the running state. Then, during the operation, the push plate motor 11 drives the charging gun push plate 8 in the charging gun insulation ejection mechanism to move outward of the charging port through the push plate threaded rod 10 connected to itself, so as to push the charging gun plug 7 inserted into the charging port base 9 out of the charging port 13, thereby switching the vehicle status to the charging port unlocked state.

[0158] In this way, when the fire detection equipment detects a burning vehicle around the vehicle and the vehicle is charging, it can control the charging unlocking module to automatically eject the charging gun from the charging pile, allowing the vehicle to quickly detach from the charging pile.

[0159] For example, to help understand the implementation flow of the fire avoidance method obtained by combining the above embodiments, please refer to Figure 6. Figure 6 is a simplified flowchart of the fire avoidance method of this application, specifically:

[0160] In this embodiment, the fire detection equipment first controls the smoke sensor installed in the vehicle to collect real-time smoke concentration parameters in the surrounding environment. Simultaneously, the fire detection equipment controls the temperature sensor installed in the vehicle to collect real-time temperature parameters in the surrounding environment. The fire detection equipment then obtains a preset first smoke concentration threshold and a first temperature parameter threshold, compares the real-time smoke concentration parameters with the first smoke concentration threshold to obtain a first comparison result, and compares the real-time temperature parameters with the first temperature parameter threshold to obtain a second comparison result. Subsequently, if the fire detection equipment detects that the first comparison result indicates the real-time smoke concentration parameter has reached the first smoke concentration threshold, or if the second comparison result indicates the real-time temperature parameter has reached the first temperature parameter threshold, it controls the camera installed in the vehicle to capture images containing... The fire detection equipment extracts the target image features from the adjacent vehicle and determines the vehicle outline based on these features. If the fire detection equipment detects an incomplete vehicle outline, it determines that the target vehicle is on fire. Next, the fire detection equipment uses a camera to capture images of the surrounding environment to generate fire information, which is then sent to the driver's mobile terminal. Then, the fire detection equipment detects the vehicle's charging port to determine its status. If the charging port is locked, the fire detection equipment controls the charging unlock module inside the vehicle to eject the charging gun from the charging port, thus switching the vehicle's status to the unlocked charging port state. Finally, the fire detection equipment determines the target escape route and controls the vehicle to travel along this route to move away from the burning vehicle.

[0161] In addition, when the fire detection equipment obtains the first comparison result and the second comparison result, and determines that the real-time smoke concentration parameter has reached the first smoke concentration threshold and the second comparison result has reached the second temperature parameter threshold, it can directly call the camera to take pictures of the surrounding environment to generate fire information and send the fire information to the mobile terminal device used by the driver, thereby controlling the vehicle status to switch to the charging port unlocked state so that it can drive away from the burning vehicle according to the target escape route.

[0162] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the fire avoidance method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
