[0067] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0068] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0069] In this embodiment, for ease of description, the following description is based on a fire detection device configured on a vehicle with a smoke sensor, a temperature sensor, a camera, and a charging unlocking module, or a mobile terminal, a data storage control terminal, a PC, or other terminals connected to an electronic control unit supporting the fire detection device as the execution subject.

[0070] Based on the above-mentioned fire detection equipment, the overall concept of the fire avoidance method of the present application is proposed here.

[0071] With the continuous development of the automobile industry, new energy vehicles have become the preferred means of transportation for more and more users in their daily travel. In particular, new energy vehicles are prone to spontaneous combustion during the charging process, or after being stationary for a long time in a high temperature environment. After spontaneous combustion, new energy vehicles will affect the surrounding parked vehicles, thereby causing huge economic losses. In related technologies, technicians usually configure a fire detection system in the vehicle, so as to determine whether there is a combustion phenomenon inside the vehicle through the signal output by the fire detection system, and then perform a fire extinguishing operation when it is determined that there is a combustion phenomenon inside the vehicle. However, the above method can only enable the vehicle to detect whether there is a combustion phenomenon itself. In this way, when other vehicles around the vehicle spontaneously combust, the vehicle itself is still easily affected, which greatly increases its own ignition risk.

[0072] In view of the above phenomenon, the present application provides a fire avoidance method, which is applied to a vehicle, and includes: obtaining combustion characteristic parameters, wherein the combustion characteristic parameters include real-time temperature parameters and / or real-time smoke concentration parameters; capturing a target image when it is detected that the combustion characteristic parameters reach a matching first parameter threshold; extracting image features of the target image, and determining whether there is a burning vehicle in the target image based on the image features; when it is determined that there is a burning vehicle in the target image, determining a target escape route, and controlling the vehicle to move along the target escape route to move away from the burning vehicle.

[0073] In this way, the present application solves the technical problem in the related art that vehicles have a high risk of ignition. That is, the present application can detect the environment in which the vehicle is located, and when the real-time temperature and / or real-time smoke concentration in the environment are identified to be abnormal, other vehicles in the environment can be identified in a timely manner, and when the presence of a burning vehicle in the surrounding environment is identified, a target escape route can be planned to stay away from the burning vehicle, thereby avoiding the situation where the vehicle is ignited by the burning vehicle, thereby achieving the technical effect of reducing the risk of vehicle ignition.

[0074] Based on the overall concept of the fire avoidance method of the present application, the embodiment of the present application provides a fire avoidance method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the fire avoidance method of the present application.

[0075] In this embodiment, the fire risk avoidance method is applied to a vehicle, and the fire risk avoidance method includes steps S10 to S40:

[0076] Step S10: Obtaining combustion characteristic parameters, wherein the combustion characteristic parameters include real-time temperature parameters and / or real-time smoke concentration parameters;

[0077] It should be noted that the vehicle is equipped with an environment detection module, which may specifically include a smoke detection unit and a temperature detection unit, and both the smoke detection unit and the temperature detection unit may be arranged on the vehicle shell. In addition, the combustion characteristic parameter is an environmental parameter in the vehicle surrounding environment, which may specifically include a real-time smoke concentration parameter and / or a real-time temperature parameter, wherein the real-time smoke concentration parameter is the unit time in the vehicle's surrounding environment The smoke concentration inside, similarly, the real-time temperature parameter is the unit time in the vehicle's surrounding environment Temperature parameters within.

[0078] In this embodiment, during operation, the fire detection device first controls the environment detection module configured on the vehicle, so as to collect combustion characteristic parameters such as real-time temperature parameters and / or real-time smoke concentration parameters generated by the vehicle's surrounding environment through the environment detection module.

[0079] For example, when the fire detection device is running, it first controls the smoke sensor configured on the vehicle, so as to collect the real-time smoke concentration parameters generated in the vehicle's surrounding environment through the smoke sensor. ; and / or, the fire detection device can also control the temperature sensor configured on the vehicle, so as to collect the real-time temperature parameters generated in the vehicle's surrounding environment through the temperature sensor .

[0080] In this way, the fire detection equipment can constantly detect the environment around the vehicle to obtain the combustion characteristic parameters of the environment around the vehicle, so as to timely determine whether there is a burning vehicle around the vehicle based on the combustion characteristic parameters.

[0081] Step S20: capturing a target image when it is detected that the combustion characteristic parameter reaches a matching first parameter threshold;

[0082] 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. It can be understood that the first parameter threshold may specifically 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 that the probability of a burning vehicle existing around the vehicle is high. In addition, the target image is image data containing a target vehicle adjacent to the vehicle.

[0083] In this embodiment, after obtaining each combustion characteristic parameter, the fire detection device further reads the storage module configured therein 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 is detected that the combustion characteristic parameter reaches the first parameter threshold, the image acquisition module configured on the vehicle is controlled, thereby capturing image data of the target vehicle adjacent to the vehicle through the image acquisition module.

[0084] For example, see Figure 2 , Figure 2 This is a target image schematic diagram of an embodiment of the fire avoidance method of the present application, in which the fire detection device obtains the real-time smoke concentration parameter and real-time temperature parameters After that, read the storage module configured by itself to obtain the real-time smoke concentration parameters The first smoke density threshold to match , the fire detection equipment then sends the real-time smoke density parameters and the first smoke density threshold The first comparison result is obtained by comparison. At the same time, the fire detection device detects the temperature of the fire according to the real-time temperature parameter. Calculate the temperature change parameters corresponding to the vehicle , the fire detection device reads the storage module to obtain the temperature change parameters Corresponding first temperature change threshold , the fire detection equipment will change the temperature parameter and the first temperature change threshold The fire detection equipment reads the first comparison result as the real-time smoke concentration parameter. Reaching the first smoke density threshold , and / or, the fire detection device reads the second comparison result as a temperature change parameter Reaching the first temperature change threshold In the case of a burning vehicle, it is determined that there may be a burning vehicle around the vehicle, and then the camera configured on the vehicle is controlled to capture the burning vehicle through the camera. Figure 2 The target image shown includes target vehicles adjacent to the vehicle.

[0085] In this way, the fire detection equipment can promptly determine whether there are burning vehicles around the vehicle based on the combustion characteristic parameters, and when it is determined that there may be burning vehicles around the vehicle, the image acquisition module configured on the vehicle is called to capture a target image containing adjacent vehicles to determine whether the target vehicle is a burning vehicle.

[0086] Step S30: extracting image features of the target image, and determining whether there is a burning vehicle in the target image according to the image features;

[0087] 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 according to the image features to determine whether there is a burning vehicle in the target image.

[0088] Exemplarily, for example, after acquiring the target image, the fire detection device extracts the image features contained in the target image, and the fire detection device determines the burning vehicle identification parameters such as the vehicle contour line, local image brightness difference, image brightness parameters, and image color features 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.

[0089] In this way, the fire detection device can identify the acquired target image to determine whether the target vehicle contained in the target image is a burning vehicle.

[0090] In a feasible implementation manner, the step of “determining whether there is a burning vehicle in the target image according to the image features” in the above step S30 may specifically include at least one of steps S301 to S304:

[0091] Step S301: determining a vehicle contour line corresponding to a target vehicle contained in the target image according to the image features, and determining that there is a burning vehicle in the target image when it is detected that the vehicle contour line is in a line-missing state;

[0092] Step S302: determining a local image brightness difference corresponding to the target vehicle according to the image feature, and determining that there is a burning vehicle in the target image when detecting that the local image brightness difference reaches a preset brightness difference threshold;

[0093] Step S303: determining a highlighted image area corresponding to the target vehicle according to the image features, and determining that a burning vehicle exists in the target image when detecting that the highlighted image area reaches a preset image area threshold;

[0094] Step S304: determining the local image color feature corresponding to the target vehicle according to the image feature, and determining that there is a burning vehicle in the target image when it is detected that the local image color feature matches a preset burning color feature.

[0095] In this embodiment, after extracting the image features of the target image, the fire detection device determines the vehicle contour line of the target vehicle contained in the target image according to the image features, and then the fire detection device identifies the vehicle contour line, so that when it is identified that the vehicle contour line is in a line-missing state, it is determined that there is a burning vehicle in the target image;

[0096] After acquiring the image features, the fire detection device can also determine the first image brightness parameter corresponding to the area where the target vehicle is located according to the image features. At the same time, the fire detection device determines the second image brightness parameter corresponding to the picture around the target vehicle according to the image features. The fire detection device processes the first image brightness parameter and the second image brightness parameter to obtain the local image brightness difference corresponding to the target vehicle. The fire detection device reads the above-mentioned storage module to obtain a preset brightness difference threshold, and when it is detected that the local image brightness difference reaches the brightness difference threshold, it is determined that there is a burning vehicle in the target image.

[0097] After acquiring the image features, the fire detection device 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 device compares the first image brightness parameter with the brightness parameter threshold, and thereby determines the highlighted 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 device reads the storage module to obtain a preset image area threshold, and determines that there is a burning vehicle in the target image when it is detected that the highlighted image area reaches the image area threshold.

[0098] After acquiring the image features, the fire detection device 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 device reads the storage module to obtain multiple preset burning image colors indicating that the vehicle is burning. The fire detection device compares the local image color with the multiple burning image colors respectively, and thus determines that there is a burning vehicle in the target image when it is determined that there is a target burning image color among the multiple burning image colors that matches the local image color.

[0099] Exemplarily, for example, after acquiring the image features, the fire detection device first determines the vehicle contour line of the target vehicle contained in the target image according to the image features, and the fire detection device identifies the vehicle contour line to determine whether the vehicle contour line is complete. When the fire detection device determines that the vehicle contour line is complete, it determines that the vehicle contour line is in a line-complete state. Similarly, when the fire detection device determines that the vehicle contour line is incomplete, it determines that the vehicle contour line is in a line-missing state. Afterwards, if the fire detection device detects that the vehicle contour line is in a line-missing state, it determines that the vehicle contour line is missing due to interference such as flames and smoke, and further determines that there is a burning vehicle in the target image.

[0100] After acquiring the image features, the fire detection device can also determine the first image brightness parameter corresponding to the area where the target vehicle is located according to the image features. At the same time, the fire detection device determines the second image brightness parameters corresponding to other image areas around the target vehicle according to the image features. The fire detection device then calculates the brightness parameter of the first image and the second image brightness parameter Calculates the local image brightness difference between the target vehicle and the surrounding environment The fire detection device then reads the above storage module to obtain a preset brightness difference threshold and converts the local image brightness difference into The fire detection device compares the brightness difference value with the preset brightness difference threshold value. When the brightness difference threshold is reached, it is determined that there may be fire in the area where the target vehicle is located, and then it is determined that there is a burning vehicle in the target image;

[0101] After acquiring the image features, the fire detection device can also determine the first image brightness parameter corresponding to the area where the target vehicle is located according to the image features. At the same time, the fire detection device reads the storage module to obtain the preset brightness parameter threshold, and converts the brightness parameter of the first image into The fire detection device reads the comparison result as the brightness parameter threshold of the first image. When the brightness parameter threshold is reached, the brightness parameter of the first image is further detected. The fire detection device compares the highlighted image area with the image area threshold, and determines that there may be fire in the area where the target vehicle is located when it is determined that the highlighted image area reaches the image area threshold, and further determines that there is a burning vehicle in the target image;

[0102] After acquiring the image features, the fire detection device can also 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 device reads the storage module to obtain multiple preset burning image colors such as red, golden, gray, black, etc. used to indicate that the vehicle is burning. The fire detection device then determines the image color area corresponding to the local image color RGB, and when it is detected that the image color area reaches a preset color area threshold, the local image color RGB is compared with multiple burning image colors. If the fire detection device determines that the local image color RGB has a matching target burning image color among the multiple burning image colors, it determines that there may be fire or smoke in the area where the target vehicle is located, and then determines that there is a burning vehicle in the target image.

[0103] In addition, in this embodiment and another embodiment, after determining that the target vehicle is a burning vehicle, the fire detection equipment can also first call the camera to shoot the surrounding environment to generate fire information, and send the fire information to the mobile terminal device used by the driver to prompt the driver.

[0104] In this way, the fire detection device can identify the acquired target image to determine whether the target vehicle contained in the target image is a burning vehicle.

[0105] Step S40: when it is determined that there is a burning vehicle in the target image, a target escape route is determined, and the vehicle is controlled to move along the target escape route to move away from the burning vehicle.

[0106] In this embodiment, after determining the burning vehicle in the target image, the fire detection device further determines a target escape route corresponding to the vehicle, and controls the vehicle to travel along the target escape route to stay away from the burning vehicle.

[0107] In this way, the fire detection equipment can enable the vehicle to automatically drive along a planned target departure route to stay away from the burning vehicle, thereby reducing the risk of the vehicle itself being ignited.

[0108] In a feasible implementation manner, the step of “determining the target deviation route” in the above step S40 may specifically include steps S401 to S403:

[0109] Step S401: obtaining a parking route corresponding to the vehicle and obtaining a preset vehicle disengagement distance;

[0110] Step S402: determining each parking space to be screened included in the parking route, and screening each parking space to be screened according to the vehicle departure distance to determine a target parking space;

[0111] Step S403: Generate a target departure route based on the target and the parking route.

[0112] In this embodiment, after determining the burning vehicle included in the target image, the fire detection device first reads the above-mentioned storage module to obtain the parking route generated by the vehicle before entering the parking space and the preset vehicle separation distance. Thereafter, 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 separation distance to determine the target parking space that is outside the vehicle separation distance and on the vehicle parking route. Finally, the fire detection device generates a target separation route based on the target parking space and the parking route.

[0113] Exemplarily, for example, after determining that a burning vehicle is included in a target image, the fire detection device first reads the above-mentioned storage module to obtain the parking route generated by the vehicle before entering the parking space and the preset vehicle separation distance D. Thereafter, the fire detection device calls the above-mentioned camera to identify the parking route to determine the idle parking spaces to be screened included in the parking route. The fire detection device then screens the idle parking spaces to be screened based on the vehicle separation distance D, and further determines the target parking space that is on the parking route and is at a distance greater than D from the current parking space. Finally, the fire detection device obtains the target separation route based on the target parking space and the parking route planning.

[0114] In this way, the fire detection equipment can enable the vehicle to automatically drive along a planned target departure route to stay away from the burning vehicle, thereby reducing the risk of the vehicle itself being ignited.

[0115] It should be noted that in this embodiment and another embodiment, after extracting the image features, the fire detection device can also identify other fire sources such as burning houses and equipment in the image based on parameters such as the contour lines of each object contained in the image features, the local image brightness difference, the highlight image area, and the local color features, and when the fire source is detected, control the vehicle to move along the target escape route to move away from the fire source. It is understandable that the present application does not limit the specific type of the fire source.

[0116] In this embodiment, during operation, the fire detection device first controls the environment detection module configured on the vehicle, so as to collect combustion characteristic parameters such as real-time temperature parameters and / or real-time smoke concentration parameters generated by the vehicle's surrounding environment through the environment detection module. After that, the fire detection device reads the storage module configured by itself 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 is detected that the combustion characteristic parameter reaches the first parameter threshold, the fire detection device controls the image acquisition module configured on the vehicle, so as to capture image data of a target vehicle adjacent to the vehicle through the image acquisition module. After that, the fire detection device extracts the image features of the target image, and the fire detection device further identifies the target vehicle contained in the target image according to the image features to determine whether there is a burning vehicle in the target image. Finally, after the fire detection device 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 stay away from the above-mentioned burning vehicle.

[0117] In this way, the present application solves the technical problem in the related art that vehicles have a high risk of ignition. That is, the present application can detect the environment in which the vehicle is located, and when the real-time temperature and / or real-time smoke concentration in the environment are identified to be abnormal, other vehicles in the environment can be identified in a timely manner, and when the presence of a burning vehicle in the surrounding environment is identified, a target escape route can be planned to stay away from the burning vehicle, thereby avoiding the situation where the vehicle is ignited by the burning vehicle, thereby achieving the technical effect of reducing the risk of vehicle ignition.

[0118] Based on the first embodiment of the present application, a second embodiment of the present application is proposed. In the second embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be repeated later. On this basis, after the above step S10, the fire avoidance method of the present application can also include steps A10~A30:

[0119] Step A10: determining the real-time temperature parameter included in the combustion characteristic parameter, and determining a second temperature parameter threshold matched by 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;

[0120] Step A20: when it is detected that the real-time temperature parameter reaches the second temperature parameter threshold, determining that there is a burning vehicle around the vehicle;

[0121] Step A30: When 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 along the target escape route to move away from the burning vehicle.

[0122] In this embodiment, after obtaining the 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 above-mentioned storage module to obtain a second temperature parameter threshold value greater than the above-mentioned first temperature parameter threshold value. After that, the fire detection device compares the real-time temperature parameter with the second temperature parameter threshold value, and thus determines that there is a burning vehicle around the vehicle when it is detected that the real-time temperature parameter reaches the second temperature parameter threshold value. 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 stay away from the above-mentioned burning vehicle.

[0123] For example, if other vehicles adjacent to the vehicle spontaneously ignite at a faster speed, causing the real-time temperature in the surrounding environment of the vehicle to rise rapidly, at this time, after obtaining each combustion characteristic parameter, the fire detection device can also first read the real-time temperature parameter contained in the combustion characteristic parameter, and read the above-mentioned storage module to obtain the corresponding real-time temperature parameter, which is greater than the above-mentioned first temperature parameter threshold value. The second temperature parameter threshold After that, the fire detection equipment will send real-time temperature parameters and the second temperature parameter threshold Compare and detect the real-time temperature parameters The second temperature parameter threshold is reached In this case, it is determined that the temperature around the vehicle rises rapidly, and then it is determined that there is a burning vehicle around the vehicle. Finally, when the fire detection equipment determines that there is a burning vehicle around the vehicle, it further determines a target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to stay away from the above-mentioned burning vehicle.

[0124] In this way, when adjacent vehicles around the vehicle spontaneously ignite at a faster speed, the fire detection equipment can detect the drastic temperature changes in a short period of time, and then control the vehicle in advance to move away from the burning vehicle along the target escape route, so as to further reduce the risk of itself being ignited.

[0125] In a feasible implementation manner, after the step of "determining the real-time temperature parameter included in the combustion characteristic parameter" in the above step A10, the fire avoidance method of the present application may further include steps A40 to A60:

[0126] Step A40: determining a temperature change parameter according to the real-time temperature parameter, and determining a second temperature change threshold matched by the temperature change parameter, wherein the second temperature change threshold is greater than the first temperature change threshold included in the first parameter threshold;

[0127] Step A50: when it is detected that the temperature change parameter reaches the second temperature change threshold, determining that there is a burning vehicle around the vehicle;

[0128] Step A60: When 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 along the target escape route to move away from the burning vehicle.

[0129] In this embodiment, after obtaining the 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 above-mentioned first temperature change threshold. Thereafter, the fire detection device compares the temperature change parameter with the second temperature change threshold, and thus determines that there is a burning vehicle around the vehicle when it is detected that the temperature change parameter reaches the second temperature change threshold. 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 stay away from the above-mentioned burning vehicle.

[0130] For example, if other vehicles adjacent to the vehicle spontaneously ignite at a relatively fast speed, causing the real-time temperature in the vehicle's surrounding environment to rise rapidly, the fire detection device will obtain the real-time temperature parameters. After that, you can also first Determine the temperature variation parameters in the vehicle's surroundings , and read the above storage module to obtain the temperature change parameters Matched, greater than the first temperature change threshold The second temperature change threshold , after which the fire detection equipment will and the second temperature change threshold Compare and compare, so that when the temperature change parameter is detected Reaching the second temperature change threshold In this case, it is determined that the temperature around the vehicle rises rapidly, and then it is determined that there is a burning vehicle around the vehicle. Finally, when the fire detection equipment determines that there is a burning vehicle around the vehicle, it further determines a target escape route corresponding to the vehicle and controls the vehicle to travel along the target escape route to stay away from the above-mentioned burning vehicle.

[0131] In this way, when adjacent vehicles around the vehicle spontaneously ignite at a faster speed, the fire detection equipment can detect the drastic temperature changes in a short period of time, and then control the vehicle in advance to move away from the burning vehicle along the target escape route, so as to further reduce the risk of itself being ignited.

[0132] In a feasible implementation manner, after the above step S10, the fire avoidance method of the present application may further include steps A70 to A90:

[0133] Step A70: determining the real-time smoke density parameter included in the combustion characteristic parameter, and determining a second smoke density threshold matched by the real-time smoke density parameter, wherein the second smoke density threshold is greater than the first smoke density threshold included in the first parameter threshold;

[0134] Step A80: when it is detected that the real-time smoke density parameter reaches the second smoke density threshold, determining that there is a burning vehicle around the vehicle;

[0135] Step A90: When 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 along the target escape route to move away from the burning vehicle.

[0136] In this embodiment, after obtaining the 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 parameters contained in the combustion characteristic parameters and read the above-mentioned storage module to obtain a second smoke concentration threshold value greater than the above-mentioned first smoke concentration threshold value. After that, the fire detection device compares the real-time smoke concentration parameter with the second smoke concentration threshold value, and thus determines that there is a burning vehicle around the vehicle when it detects that the real-time smoke concentration parameter reaches the second smoke concentration threshold value. 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 stay away from the above-mentioned burning vehicle.

[0137] For example, if other vehicles adjacent to the vehicle spontaneously ignite at a relatively fast speed, and the smoke emitted by the spontaneously ignited vehicle quickly spreads to the vicinity of the vehicle, the fire detection device can first read the real-time smoke concentration parameter contained in the combustion characteristic parameters after obtaining each combustion characteristic parameter. , and read the above storage module to obtain real-time smoke concentration parameters Matched, greater than the first smoke concentration threshold The second smoke density threshold After that, the fire detection equipment will send real-time smoke density parameters The second smoke density threshold Compare and detect the real-time smoke concentration parameters Reaching the second smoke density threshold In the case of a fire, it is determined that the smoke generated by the fire spreads around the vehicle, and then it is determined that there is a burning vehicle around the vehicle. Finally, when the fire detection equipment determines that there is a burning vehicle around the vehicle, it further determines a target escape route corresponding to the vehicle, and controls the vehicle to travel along the target escape route to stay away from the above-mentioned burning vehicle.

[0138] In this way, when adjacent vehicles around the vehicle spontaneously ignite at a faster speed, the fire detection equipment can detect the drastic change in smoke concentration in the surrounding environment in a short period of time, and then control the vehicle in advance to move away from the burning vehicle along the target escape route, so as to further reduce the risk of itself being ignited.

[0139] Based on the first embodiment and / or the second embodiment of the present application, the third embodiment of the present application is proposed here. In the third embodiment of the present application, the same or similar contents as the above embodiments can be referred to the above introduction, and will not be repeated later. On this basis, the vehicle also includes a charging unlocking module. After the above step S30, the fire avoidance method of the present application can also include steps B10~B20:

[0140] Step B10: in the case where it is determined that there is a burning vehicle in the target image, detecting the vehicle state of the vehicle;

[0141] Step B20: When it is detected that the vehicle state is a charging port locked state, the vehicle state is switched to a charging port unlocked state through a charging unlocking module, and the step of determining the target exit route is executed.

[0142] Please note that, please refer to Figure 3 , Figure 3 This is a schematic diagram of a charging module involved in an embodiment of the fire avoidance method of the present application, such as Figure 3 As shown, when the charging port is locked, the charging gun 12 is inserted into the charging port 13, and the charging gun lock tongue 1 inside the charging gun 12 fits with the charging port lock buckle 2 inside the charging port; in addition, when the charging port is unlocked, the charging gun lock tongue 1 and the charging port lock buckle 2 are separated, and the charging gun 12 is removed from the charging port 13.

[0143] In this embodiment, after determining that there is a burning vehicle in the target image, the fire detection device may further detect the charging port configured in the vehicle to determine the vehicle status of the vehicle. Thereafter, if the fire detection device determines that the vehicle status is a charging port locked state, the charging unlocking module configured in the vehicle is controlled to adjust the vehicle status from the charging port locked state to the charging port unlocked state, thereby determining the target disengagement route corresponding to the vehicle, and controlling the vehicle to travel along the target disengagement route to stay away from the above-mentioned burning vehicle.

[0144] Exemplarily, for example, after the fire detection device recognizes that there is a burning vehicle in the above-mentioned target image, the fire detection device further detects the charging port configured in the vehicle to determine whether the charging port lock configured in the charging port is in contact with the charging gun lock tongue of the charging gun in the external charging pile. If the fire detection device detects that the charging port lock and the charging gun lock tongue are in contact, it determines that the vehicle state of the vehicle is the charging port locked state. Thereafter, the fire detection device controls the charging unlocking module configured in the vehicle to pop the charging gun out of the charging port through the charging unlocking module, thereby switching the vehicle state from the charging port locked state to the charging port unlocked state, and then determining the target escape route, and controlling the vehicle to travel along the target escape route to stay away from the above-mentioned burning vehicle.

[0145] In this way, when the fire detection equipment identifies that there is a burning vehicle around the vehicle and the vehicle is in a charging state, it can control the charging unlocking module to automatically pop out the charging gun in the charging pile from the vehicle, allowing the vehicle to quickly detach from the charging pile and automatically drive along the planned target detachment route to move away from the burning vehicle, further reducing the risk of the vehicle being ignited.

[0146] In a feasible implementation manner, the charging unlocking module includes a lock tongue unlocking mechanism and a charging gun insulation ejection mechanism; the step of "switching the vehicle state to the charging port unlocking state through the charging unlocking module" in the above step B20 may specifically include steps B201~B202:

[0147] Step B201: adjusting the charging port and the charging gun of the vehicle to separate by the lock tongue unlocking mechanism;

[0148] Step B202: Push the charging gun out of the charging port through the charging gun insulation pushing mechanism to switch the vehicle state to the charging port unlocked state.

[0149] In this embodiment, when the fire detection device detects that the vehicle is in a charging port locked state, it first controls the lock tongue unlocking mechanism in the charging unlocking module to adjust the charging gun lock tongue and the charging port lock buckle to disengage through the lock tongue unlocking mechanism, thereby separating the charging port and the charging gun. Afterwards, the fire detection device controls the charging gun insulation pushing mechanism in the charging unlocking module to push out the charging gun connected to the charging port through the charging gun insulation pushing mechanism, thereby switching the vehicle state to the charging port unlocked state.

[0150] Exemplarily, for example, when the fire detection device detects that the vehicle is in a charging port locked state, it first controls the charging unlocking module configured in the charging port to mobilize the lock tongue unlocking mechanism contained in the charging unlocking module, thereby striking the charging gun lock tongue through the lock tongue unlocking mechanism to separate the charging gun lock tongue and the charging port lock. Afterwards, the fire detection device controls the charging gun insulation pushing mechanism contained in the charging unlocking module, thereby pushing the charging gun plug through the charging gun insulation pushing mechanism to disengage the charging gun plug from the charging port, thereby switching the vehicle state to the charging port unlocked state.

[0151] In this way, when the fire detection equipment identifies that there are burning vehicles around the vehicle and the vehicle is in a charging state, it can control the charging unlocking module to automatically pop out the charging gun in the charging pile from the vehicle, allowing the vehicle to quickly detach from the charging pile.

[0152] In a feasible implementation manner, the lock tongue unlocking mechanism includes an unlocking motor, an unlocking lever pull rope, and an unlocking lever, the unlocking motor is connected to the unlocking lever through the unlocking lever pull rope, and the unlocking lever is connected to the charging gun lock tongue in the charging gun; the above step B201 may specifically include steps B2011~B2012:

[0153] Step B1011: controlling the unlocking motor to enter a running state;

[0154] Step B1012: The unlocking lever is controlled by the unlocking motor and the unlocking lever pull rope so that the unlocking lever hits the charging gun lock tongue, thereby separating the charging gun lock tongue from the charging port of the vehicle.

[0155] In this embodiment, when the fire detection device detects that the vehicle is in a locked state of the charging port, it first controls the charging unlocking module configured in the charging port to control the unlocking motor in the lock tongue unlocking mechanism in the charging unlocking module to enter an operating state. Thereafter, the unlocking motor drives the unlocking lever pull rope connected to itself during operation, and drives the unlocking lever connected to the unlocking lever pull rope through the unlocking lever pull rope, so that the unlocking lever hits the charging gun lock tongue connected to the charging port lock, thereby separating the charging gun lock tongue connected to the charging port lock.

[0156] For example, see Figure 4 , Figure 4 FIG. 1 is a schematic diagram of a lock tongue unlocking mechanism according to an embodiment of the fire avoidance method of the present application. When the fire detection device detects that the vehicle is in a locked state of the charging port, the fire detection device first controls the charging unlocking module configured in the charging port to call the following method: Figure 4The lock tongue unlocking mechanism shown in the figure makes the unlocking motor 3 in the lock tongue unlocking mechanism run. After that, the unlocking motor 3 drives the unlocking lever pull rope 4 connected to itself during operation, and the unlocking lever pull rope 4 drives the unlocking lever 5 connected to itself, so that the unlocking lever 5 is pried based on the moving fulcrum 6 on the charging port base 9, so that the end of the unlocking lever 5 hits the charging gun lock tongue 1 to separate the charging gun lock tongue 1 and the charging port lock buckle 2.

[0157] In this way, when the fire detection equipment identifies that there are burning vehicles around the vehicle and the vehicle is in a charging state, it can control the charging unlocking module to automatically pop out the charging gun in the charging pile from the vehicle, allowing the vehicle to quickly detach from the charging pile.

[0158] In a feasible implementation manner, the charging gun insulating push mechanism includes a push plate motor, a push plate screw, and a charging gun insulating push plate, the push plate motor is connected to the push plate screw, the push plate screw is connected to the charging gun insulating push plate, and the charging gun insulating push plate is connected to the charging gun; the above step B202 may specifically include steps B2021~B2022:

[0159] Step B2021: Control the push plate motor to enter the running state;

[0160] Step B2022: The insulating push plate of the charging gun is driven to operate through the operating state and the push plate screw to push the charging gun out of the charging port, thereby switching the vehicle state to the charging port unlocked state.

[0161] In this embodiment, please refer to Figure 5 , Figure 5 This is a schematic diagram of the insulation ejection mechanism of the charging gun involved in an embodiment of the fire avoidance method of the present application, such as Figure 5 As shown, after determining that the charging gun lock tongue 1 and the charging port lock buckle 2 are separated, the fire detection device further controls the charging gun insulation pushing mechanism configured in the charging unlocking module, so that the push plate motor 11 configured in the charging gun insulation pushing mechanism enters the operating state. After that, during the operation, the push plate motor 11 drives the charging gun push plate 8 in the charging gun insulation pushing mechanism to move toward the outside of the charging port through the push plate threaded rod 10 connected to itself, so as to push the charging gun plug 7 inserted in the charging port base 9 out of the charging port 13, thereby switching the vehicle state to the charging port unlocked state.

[0162] In this way, when the fire detection equipment identifies that there are burning vehicles around the vehicle and the vehicle is in a charging state, it can control the charging unlocking module to automatically pop out the charging gun in the charging pile from the vehicle, allowing the vehicle to quickly detach from the charging pile.

[0163] For example, in order to help understand the implementation process of the fire avoidance method obtained by combining this embodiment with the above embodiments, please refer to Figure 6 , Figure 6 This is a brief flow chart of the fire avoidance method of this application, specifically:

[0164] In this embodiment, when the fire detection device is running, it first controls the smoke sensor configured on the vehicle to collect real-time smoke concentration parameters in the vehicle's surrounding environment. At the same time, the fire detection device controls the temperature sensor configured on the vehicle to collect real-time temperature parameters in the vehicle's surrounding environment. The fire detection device then obtains a preset first smoke concentration threshold and a first temperature parameter threshold, and compares the real-time smoke concentration parameter with the first smoke concentration threshold to obtain a first comparison result, and compares the real-time temperature parameter with the first temperature parameter threshold to obtain a second comparison result. Thereafter, when the fire detection device detects that the first comparison result is that the real-time smoke concentration parameter reaches the first smoke concentration threshold, or when the fire detection device detects that the second comparison result is that the real-time temperature parameter reaches the first temperature parameter threshold, it controls the camera configured on the vehicle to capture images containing the relevant information. The fire detection device extracts the target image features and determines the vehicle contour line corresponding to the target vehicle according to the image features. If the fire detection device detects that the vehicle contour line is incomplete, it determines that the target vehicle is a burning vehicle. After that, the fire detection device calls the camera to shoot the surrounding environment to generate fire information, and sends the fire information to the mobile terminal device used by the driver. Then, the fire detection device detects the charging port configured for the vehicle to determine the vehicle status. If the fire detection device detects that the vehicle status is the charging port locked state, the charging unlocking module configured in the vehicle is controlled to control the charging gun to pop out of the charging port through the charging unlocking module, thereby switching the vehicle status to the charging port unlocking state. Finally, the fire detection device determines the target escape route and controls the vehicle to travel along the target escape route to stay away from the burning vehicle.

[0165] In addition, when the fire detection device obtains the first comparison result and the second comparison result, and determines that the first comparison result is that the real-time smoke concentration parameter reaches the first smoke concentration threshold, and determines that the second comparison result is that the real-time temperature parameter reaches the second temperature parameter threshold, the camera can be directly called to shoot the surrounding environment to generate fire information, and the fire information is sent to the mobile terminal device used by the driver, thereby controlling the vehicle status to switch to the charging port unlocked state, so as to drive according to the target departure route and stay away from the above-mentioned burning vehicle.
