[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0050] In a first aspect, an embodiment of the present application provides a method for controlling the safety of a charging station.

[0051] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the method for controlling the safety of a charging station in the present application. Figure 1 As shown, the control method for charging station safety includes:

[0052] Step S10: When an alarm signal is detected, the battery temperature, the temperature under the parking space and the flame area are obtained.

[0053] Exemplarily, in an embodiment of the present application, when the smoke concentration detected by the ion smoke sensor below the parking space or above the charging station reaches a certain threshold, an alarm signal will be triggered. When the alarm signal is detected, the system will trigger the temperature sensor to read the battery temperature and the temperature under the parking space, and monitor the flame color, flame image changes, flame tip and other flame characteristics and flame area through video capture of the charging station.

[0054] Specifically, the battery temperature can be monitored to monitor the working status of the battery in real time to ensure that it is within a safe range; the ground temperature sensor can be used to collect the temperature under the parking space to detect whether there is overheating or abnormal heat source; the video of the charging station can be used to determine the presence of flames, and then determine the area and spread of the flames. It is understandable that after obtaining the above data, these data can be comprehensively analyzed, that is, according to the preset threshold, it is determined whether further emergency response measures are needed to ensure the safety of the vehicle and the charging station environment.

[0055] Step S20: Determine the accident level based on the battery temperature, the temperature below the parking space, and the flame area.

[0056] For example, in the embodiments of the present application, the battery temperature is a key parameter for determining whether the battery is overheated or malfunctioning, especially in electric vehicles. The temperature change of the battery is directly related to safety and fire risk. A higher battery temperature means a higher risk level of the accident. The temperature below the parking space reflects the possible spread of the fire and the intensity of the fire source. If the flame contacts the ground or the structure under the parking space, the temperature will rise sharply and even cause a secondary fire. The higher the temperature below the parking space, the more serious the spread of the fire and the more difficult it is to control the fire. The flame area is an intuitive indicator for evaluating the spread and severity of the fire. A larger flame area indicates that the fire is out of control, that is, the accident level is higher.

[0057] It should be understood that the battery temperature, the temperature under the parking space and the flame area can comprehensively reflect the speed and scope of the fire. The higher the battery temperature, the more severe the thermal runaway phenomenon may occur; the higher the temperature under the parking space, the fire may spread quickly to the surrounding area; the increase in the flame area directly shows the severity of the fire. Therefore, when the alarm signal has been detected, the combination of the above three parameters can comprehensively evaluate the severity, development trend and spread speed of the fire, and then help determine the level of the accident, so as to take appropriate emergency response measures to ensure the safety of personnel and minimize property losses.

[0058] It should be noted that synchronous communication between the charging station and the vehicle can be achieved through Bluetooth authentication and WIFI signals, and a dedicated video monitor can be set up in each parking space. When the charging station receives any level of accident conditions, the accident level will be sent to the user's mobile app and the charging station cloud platform within 1 second, and the real-time parking space monitoring screen will be sent at the same time. After receiving the accident condition reminder, the charging station will immediately automatically draw the gun through the charging robot, and automatically send a text message within 1 second to call the user's mobile phone number through AI to inform the accident level.

[0059] Step S30: If it is detected that the accident site is at the vehicle end, the accident vehicle is controlled to be transferred to the accident handling area and / or the distance between the accident vehicle and non-accident vehicles is controlled based on the accident level.

[0060] For example, in the embodiments of the present application, the accident site refers to the specific location or area where the accident occurred; the accident handling area refers to a specific area set up after the accident occurs in order to effectively and safely handle the accident; the accident vehicle refers to the vehicle directly involved in the accident; and the non-accident vehicle refers to other vehicles in the accident area that are not directly involved in the accident.

[0061] Specifically, when the accident location of the fire is detected at the vehicle end, it indicates that the accident occurred on a specific vehicle, which usually creates a greater safety risk. At this time, the accident vehicle can be controlled to be transferred to the accident handling area according to the level of the accident; if the accident level is low, it means that the risk on the vehicle end is low, then the accident vehicle can be controlled to move slowly to the accident handling area, or the distance between the accident vehicle and non-accident vehicles can be controlled to keep the accident vehicle away from non-accident vehicles to ensure the safety of non-accident vehicles; when the level of the accident is medium, there may be risks such as sparks and battery overheating. At this time, the accident vehicle can be transferred to the accident handling area while controlling the accident vehicle to maintain a certain distance from non-accident vehicles, which helps prevent non-accident vehicles from entering dangerous areas and avoid collision risks; if the accident level is high, such as fire or battery thermal runaway, the accident vehicle can be quickly transferred to the accident handling area while controlling the accident vehicle to maintain a relatively long distance from non-accident vehicles to effectively prevent the fire from spreading to the surrounding areas, thereby ensuring the safety of non-accident vehicles.

[0062] Step S40: If it is detected that the accident location is not at the vehicle end, the non-accident vehicle is controlled to be transferred to a safe area at a different location based on the accident level.

[0063] Exemplarily, in the embodiments of the present application, in the charging station, the non-vehicle end refers to the facilities themselves, such as charging piles, electrical facilities, etc.; the safety area refers to a special area set up after an accident to protect the safety of personnel and avoid secondary accidents or larger-scale hazards; specifically, the level of the accident determines the distance between the safety area and the accident site, wherein the lower the accident level, the smaller the distance between the safety area and the accident site; the higher the accident level, the greater the distance between the safety area and the accident site, so different accident levels correspond to safety areas at different locations; non-vehicle-end accidents may not involve direct collisions between vehicles, but they will still pose a threat to the normal operation of the charging station and vehicle safety. Therefore, if a non-vehicle-end accident is detected, it is necessary to timely control the transfer of non-accident vehicles based on the accident level to ensure that non-accident vehicles are safely transferred to safety areas at different locations to ensure the normal operation of the charging station and the safety of all vehicles.

[0064] When the alarm signal is detected, the present application obtains the battery temperature, the temperature under the parking space and the flame area; the accident level is determined based on the battery temperature, the temperature under the parking space and the flame area, so as to take different protective measures for the charging station and the charging vehicle according to the accident level; wherein, if the accident site is detected to be the vehicle side, the accident vehicle is controlled to be transferred to the accident handling area and / or the distance between the accident vehicle and the non-accident vehicle is controlled based on the accident level to prevent the fire or other dangers from spreading to the charging station facilities; if the accident site is detected to be not the vehicle side, the non-accident vehicle is controlled to be transferred to safe areas at different locations based on the accident level to prevent non-accident vehicles from entering the dangerous area, while ensuring the safety of the vehicle. The present application can quickly take appropriate emergency measures to protect the charging station and the charging vehicle in the event of a safety accident, reduce losses and effectively control the spread of fire by judging the accident level and detecting the accident site; it not only improves the safety of the charging station and the charging vehicle, but also ensures the stability and reliability of the charging process.

[0065] Further, in one embodiment, referring to Figure 2 As shown, the accident level is determined based on the battery temperature, the temperature under the parking space and the flame area, including:

[0066] Step S201: if it is detected that the battery temperature is not greater than a preset first temperature threshold and the temperature below the parking space is not greater than a preset second temperature threshold, the accident level is determined to be the first level;

[0067] Step S202: if it is detected that the battery temperature is greater than a preset first temperature threshold, the temperature below the parking space is greater than a preset second temperature threshold, and the flame area is less than a preset area threshold, the accident level is determined to be the second level;

[0068] Step S203: If the flame area is detected to be greater than or equal to the preset area threshold, the accident level is determined to be the third level, wherein the first temperature threshold is greater than the second temperature threshold, and the severity of the accident is ranked from low to high as follows: first level, second level, and third level.

[0069] For example, in the embodiment of the present application, the specific values ​​of the preset first temperature threshold, the preset second temperature threshold, and the preset area threshold can be determined according to actual needs and are not limited here. For example, the preset first temperature threshold can be preferably 100°C, the preset second temperature threshold can be preferably 80°C, and the preset area threshold can be preferably 1m 2 ; The severity of the accident is ranked from low to high as follows: first level, second level, and third level.

[0070] Specifically, when an alarm signal has been detected, if the battery temperature is detected to be ≤ the preset first temperature threshold and the temperature below the parking space is ≤ the preset second temperature threshold, it means that the fire risk is low, and the accident level can be determined to be the first level; if any one of the following situations is detected: the battery temperature is greater than the preset first temperature threshold, the temperature below the parking space is greater than the preset second temperature threshold, and the flame area is less than the preset area threshold, it indicates that a more serious fire has occurred and the flame area is small, and the accident level can be determined to be the second level; if the flame area is detected to be ≥ the preset area threshold, it indicates that the fire has spread to a larger area, and the accident level can be determined to be the third level.

[0071] It should be understood that the embodiments of the present application can accurately determine the risk level of fire through comprehensive monitoring and evaluation of battery temperature, temperature under the parking space and flame area, thereby achieving timely, scientific and reasonable emergency response; this accurate risk assessment and accident level determination not only helps to improve the efficiency of fire handling, but also ensures personnel safety, optimizes resource allocation, and improves the level of system intelligence, thereby minimizing the losses and impacts of fire.

[0072] Further, in one embodiment, referring to Figure 3 As shown, the control of transferring the accident vehicle to the accident handling area and / or controlling the distance between the accident vehicle and non-accident vehicles based on the accident level includes:

[0073] Step S301: If the accident level is the first level, the accident vehicle is moved to a preset accident handling area based on the preset car moving robot;

[0074] Step S302: If the accident level is the second level, the accident vehicle is controlled to be transferred to a preset accident handling area based on the preset car moving robot, and during the transfer process, the distance between the accident vehicle and non-accident vehicles is controlled to be greater than a preset first distance threshold;

[0075] Step S303: If the accident level is the third level, the accident vehicle is transferred to a preset accident handling area based on the preset car-moving robot and the distance between the accident vehicle and non-accident vehicles is controlled to be greater than a preset second distance threshold during the transfer process, wherein the first distance threshold is less than the second distance threshold.

[0076] For example, in the embodiment of the present application, the specific values ​​of the preset first distance threshold and the preset second distance threshold can be determined according to actual needs and are not limited here. For example, the preset first distance threshold can preferably be 5m, and the preset second distance threshold can preferably be 10m; the preset car moving robot refers to an automated equipment that has been programmed and configured in advance and has the ability to perform accident vehicle transfer tasks in specific scenarios. The working principle of the car moving robot is common knowledge in the field and will not be elaborated here for the sake of brevity of description.

[0077] Specifically, after the accident level is determined, the car moving robot can be controlled to perform different transfer tasks according to the accident level; if the accident level is the first level and the fire severity is low, the accident vehicle can be transferred to the designated accident handling area or the distance between the accident vehicle and non-accident vehicles can be controlled by the car moving robot; if the accident level is the second level, the accident vehicle can be transferred to the accident handling area by the car moving robot, and during the transfer process, ensure that the distance between the accident vehicle and the surrounding non-accident vehicles is greater than a preset first distance threshold, so as to prevent the accident vehicle from colliding or interfering with other vehicles; if the accident level is the third level, the car moving robot needs to perform stricter control, that is, it needs to ensure that the distance between the accident vehicle and non-accident vehicles during the transfer process is greater than a preset second distance threshold, so as to ensure that potential safety hazards can be effectively avoided in higher-risk situations.

[0078] Furthermore, in one embodiment, the method further includes:

[0079] If the accident level is the first level, the preset first speed is used as the driving speed of the car moving robot;

[0080] If the accident level is the second level, the preset second speed is used as the driving speed of the car-moving robot;

[0081] If the accident level is the third level, the preset third speed is used as the driving speed of the car-moving robot, wherein the first speed, the second speed, and the third speed are arranged from small to large as follows: first speed, second speed, and third speed.

[0082] Exemplarily, in the embodiment of the present application, the specific values ​​of the preset first speed, the preset second speed, and the preset third speed can be determined according to actual needs, and they only need to be sorted from small to large as: first speed, second speed, third speed. No limitation is made here. For example, the preset first speed can be preferably 10km / h, the preset second speed can be preferably 20km / h, and the preset third speed can be preferably 30km / h.

[0083] Specifically, in the work flow of the car moving robot, the driving speed matching the level can be determined according to the judgment result of the accident level; specifically, when the accident level is the first level, the preset first speed can be used as the driving speed of the car moving robot. This speed is usually low, which can ensure the transfer stability and safety of the vehicle in low-risk situations; when the accident level is the second level, the preset second speed can be used as the driving speed of the robot. This speed is greater than the first speed, but still within a safe and controllable range, and is used for medium-risk accident transfer; when the accident level is the third level, the preset third speed can be used as the driving speed of the robot. This speed is the largest of the three preset speeds, and is used to handle high-risk transfer tasks, ensuring that the accident vehicle can be quickly and effectively transferred to the designated area in an emergency.

[0084] It is understandable that by linking the driving speed of the car moving robot with the accident level, the system can adopt the most appropriate driving speed according to different risk situations, which not only ensures the safety, stability and efficiency of the transfer process, but also ensures rapid response in emergencies while avoiding waste of resources and equipment damage.

[0085] Furthermore, in one embodiment, the controlling of the non-accident vehicle to be transferred to a safe area at a different location based on the accident level includes:

[0086] If the accident level is the first level, control a first non-accident vehicle to move to a first safety area, wherein the first non-accident vehicle is a vehicle that is at a preset first distance from the accident site;

[0087] If the accident level is the second level, control a second non-accident vehicle to move to a second safety area, wherein the second non-accident vehicle is a vehicle that is at a preset second distance from the accident site, wherein the preset first distance is less than the preset second distance;

[0088] If the accident level is the third level, all non-accident vehicles are controlled to be transferred to the third safety area, wherein the distances between the safety areas and the accident site are arranged from small to large as follows: the first safety area, the second safety area, and the third safety area.

[0089] Exemplarily, a safety area refers to an area used to ensure the safety of personnel and vehicles in the event of a fire accident or emergency. Safety areas at different locations include a first safety area, a second safety area, and a third safety area. The safety areas in the embodiment of the present application can be divided according to the distance from the accident site, wherein the distance between the safety area and the accident site is arranged from small to large as follows: a first safety area, a second safety area, and a third safety area. For example, the first safety area may be preferably 20 meters away from the accident site, the second safety area may be preferably 50 meters away from the accident site, and the third safety area may be preferably 100 meters away from the accident site. The specific values ​​of the preset first distance and the preset second distance can be determined according to actual needs, as long as the preset first distance is less than the preset second distance, and no limitation is made here. For example, the preset first distance may be preferably 5 meters, and the preset second distance may be preferably 10 meters. The first non-accident vehicle refers to a vehicle that is closer to the accident site, such as a distance of 5 meters (i.e., the first distance) between the first non-accident vehicle and the accident site, and the second non-accident vehicle refers to a vehicle that is farther away from the accident site, such as a distance of 10 meters (i.e., the second distance) between the first non-accident vehicle and the accident site.

[0090] Specifically, when controlling non-accident vehicles to be transferred to safe areas at different locations, in addition to being achieved through a car moving robot, it can also be achieved through the vehicle's automatic driving function; wherein, in the workflow of the car moving robot or the vehicle's automatic driving, non-accident vehicles can be controlled to be transferred to safe areas at different locations according to different accident levels; when the accident level is the first level, the first non-accident vehicle can be controlled to be transferred to the first safety area, and when the accident level is the second level, the second non-accident vehicle can be controlled to be transferred to the second safety area, to ensure that vehicles closer to the accident site are given priority; if the accident level is the third level, all non-accident vehicles can be controlled to be uniformly transferred to the third safety area.

[0091] Furthermore, in one embodiment, controlling the first non-accident vehicle to transfer to the first safety area includes:

[0092] If the number of the first non-accident vehicles is less than a preset first number threshold, controlling the first non-accident vehicles to transfer to a first safety area based on the preset first number of target routes;

[0093] If the number of the first non-accident vehicles is not less than a preset first number threshold and the number of the first non-accident vehicles is not greater than a preset second number threshold, controlling the first non-accident vehicles to transfer to the first safety area based on the preset second number of target routes;

[0094] If the number of the first non-accident vehicles is greater than a preset second number threshold, the first non-accident vehicles are controlled to be transferred to the first safety area based on a target route based on a preset third number, wherein the preset first number, the preset second number, and the preset third number are sorted from small to large as follows: preset first number, preset second number, and preset third number.

[0095] Exemplarily, in an embodiment of the present application, when controlling the first non-accident vehicle to transfer to the first safety area, the correspondence between the quantity threshold range and the target route can be set first, and then the target route can be determined based on the relationship between the number of the first non-accident vehicles and the preset quantity threshold range, and then the first non-accident vehicle can be controlled to transfer to the first safety area according to the target route.

[0096] Among them, it should be noted that the specific values ​​of the preset first quantity threshold, the preset second quantity threshold, the preset first quantity, the preset second quantity, and the preset third quantity can be determined according to actual needs, and it is only necessary to satisfy that the preset first quantity threshold is less than the preset second quantity threshold and the preset first quantity, the preset second quantity, and the preset third quantity are arranged from small to large as: preset first quantity, preset second quantity, preset third quantity, and are not limited here; the target route refers to the shortest route to the safe area; for example, the preset first quantity threshold may preferably be 2, and the preset second quantity threshold may preferably be 4, then the quantity threshold range includes (0, 2), [2, 4], [4, +∞); for example, the preset first quantity may preferably be 1 (that is, the target route is 1), the preset second quantity may preferably be 2 (that is, the target routes are 2), and the preset third quantity may preferably be 3 (that is, the target routes are 3).

[0097] Based on this, it is assumed that the target route corresponding to the threshold range of the number of first non-accident vehicles (0, 2) is 1, the target route corresponding to the threshold range of the number of first non-accident vehicles [2, 4] is 2, and the target route corresponding to the threshold range of the number of first non-accident vehicles (4, ∞) is 3, and the 3 routes have no intersection within 10 meters from the charging station; then, if the number of first non-accident vehicles is 3, it meets the requirement that the number of first non-accident vehicles is within the interval [2, 4], so there are 2 target routes. At this time, the first non-accident vehicle can be controlled to be transferred to the first safety area according to these 2 target routes.

[0098] It can be understood that when controlling the second non-accident vehicle to transfer to the second safety area, the corresponding relationship between the number threshold range and the target route can also be set first, and then the target route is determined in combination with the relationship between the number of the second non-accident vehicle and the preset number threshold range, and then the second non-accident vehicle is controlled to transfer to the second safety area according to the target route. Specifically, assuming that when the number threshold range of the second non-accident vehicle is (0, 3), the corresponding target route is 1, when the number threshold range of the second non-accident vehicle is [3, 9], the corresponding target route is 3 and the 3 routes have no intersection within 10 meters from the charging station, when the number threshold range of the second non-accident vehicle is (9, ∞), the corresponding target route is 4 and the 4 routes have no intersection within 10 meters from the charging station; then, if the number of the second non-accident vehicle is 6, it meets the condition that the number of the second non-accident vehicle is within the interval [3, 9], so the target route is 3, and the second non-accident vehicle can be controlled to transfer to the second safety area according to these 3 target routes.

[0099] It should be noted that when the accident level is the third level, the corresponding number of target routes should satisfy ≥ the maximum number of target routes of the first two levels. Therefore, it is preferred to plan four target routes (i.e., the four nearest routes) through a preset planning algorithm, and control all non-accident vehicles to be transferred to the third safety area according to these four nearest routes. The working principle and implementation process of the planning algorithm are common knowledge in the field and will not be elaborated here for the sake of brevity.

[0100] When the alarm signal is detected, the present application obtains the battery temperature, the temperature under the parking space and the flame area; the accident level is determined based on the battery temperature, the temperature under the parking space and the flame area, so as to take different protective measures for the charging station and the charging vehicle according to the accident level; wherein, if the accident site is detected to be the vehicle side, the accident vehicle is controlled to be transferred to the accident handling area and / or the distance between the accident vehicle and the non-accident vehicle is controlled based on the accident level to prevent the fire or other dangers from spreading to the charging station facilities; if the accident site is detected to be not the vehicle side, the non-accident vehicle is controlled to be transferred to safe areas at different locations based on the accident level to prevent non-accident vehicles from entering the dangerous area, while ensuring the safety of the vehicle. The present application can quickly take appropriate emergency measures to protect the charging station and the charging vehicle in the event of a safety accident, reduce losses and effectively control the spread of fire by judging the accident level and detecting the accident site; it not only improves the safety of the charging station and the charging vehicle, but also ensures the stability and reliability of the charging process.
