Technical Field

[0001] This application relates to the field of charging station technology, and specifically to a control method, system, device, and readable storage medium for charging station safety. Background Art

[0002] With the rapid development of electric vehicles and their charging infrastructure, the demands of vehicle owners and charging station maintenance personnel for improved safety and timely response are increasing. Currently, relevant technologies mainly monitor and report potential safety risks during charging through alarms and recording. However, when safety risks occur, vehicle owners and charging station maintenance personnel are often unable to proactively protect the charging station or other charging vehicles, making it difficult to change the outcome of the accident.

[0003] Therefore, how to protect charging stations and charging vehicles in the event of a safety accident is an urgent problem that needs to be solved. Summary of the Invention

[0022] In conjunction with the first aspect, in one implementation, the method of controlling the transfer of non-accident vehicles to safe areas at different locations based on accident level includes:

[0023] If the accident level is Level 1, then the first non-accident vehicle is controlled to be transferred to the first safe area. The first non-accident vehicle is a vehicle that is at a preset first distance from the accident site.

[0024] If the accident level is Level 2, then control the second non-accident vehicle to be transferred to the second safe area. 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.

[0025] If the accident level is Level 3, all non-accident vehicles will be moved to the third safety zone. The distances between the safety zones and the accident site are ordered from smallest to largest as follows: first safety zone, second safety zone, and third safety zone.

[0026] In conjunction with the first aspect, in one implementation, controlling the transfer of the first non-accident vehicle to the first safe area includes:

[0027] If the number of first non-accident vehicles is less than a preset first number threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset first number.

[0028] If the number of first non-accident vehicles is not less than a preset first quantity threshold and the number of first non-accident vehicles is not greater than a preset second quantity threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset second quantity.

[0029] If the number of first non-accident vehicles is greater than the preset second number threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset third number. The preset first number, preset second number, and preset third number are ordered from smallest to largest as follows: preset first number, preset second number, and preset third number.

[0030] Secondly, embodiments of this application provide a control system for the safety of a charging station, the control system comprising:

[0032] The second processing module is used to determine the accident level based on the battery temperature, the temperature under the parking space, and the flame area.

[0033] The third processing module is used to control the transfer of the accident vehicle to the accident handling area and / or control the distance between the accident vehicle and the non-accident vehicle based on the accident level if the accident location is detected to be at the vehicle end.

[0034] The fourth processing module is used to control non-accident vehicles to move to safe areas at different locations based on the accident level if the accident location is detected to be a non-vehicle end.

[0037] If any one of the following is detected: the battery temperature is greater than a preset first temperature threshold, the temperature under the parking space is greater than a preset second temperature threshold, or the flame area is less than a preset area threshold, then the accident level is determined to be Level 2.

[0038] If the detected flame area is greater than or equal to a preset area threshold, the accident level is determined to be Level 3, wherein the first temperature threshold is greater than the second temperature threshold, and the severity of the accident is sorted from low to high as: Level 1, Level 2, Level 3.

Specifically, if the accident location is detected at the vehicle end, the system controls the transfer of the affected vehicle to the accident handling area and / or controls the distance between the affected vehicle and non-affected vehicles to prevent the fire or other hazards from spreading to the charging station facilities. If the accident location is detected at a non-vehicle end, the system controls the transfer of non-affected vehicles to different safe areas to prevent them from entering dangerous areas while ensuring vehicle safety. This application, through accident level determination and accident location detection, enables the rapid implementation of appropriate emergency measures to protect the charging station and charging vehicles in the event of a safety accident, reducing losses and effectively controlling the spread of fire. This not only improves the safety of the charging station and charging vehicles but also ensures stability and reliability during the charging process. Attached Figure Description

[0048] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] In a first aspect, embodiments of this application provide a method for controlling the safety of a charging station.

[0051] In one embodiment, reference is made to Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of the control method for charging station safety according to this application. Figure 1 As shown, the safety control methods for charging stations include:

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

[0053] As an example, in this embodiment of the 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 below the parking space, and monitor flame characteristics such as flame color, flame image changes, flame tip angles and flame area through video capture of the charging station.

[0054] Specifically, battery operating status can be monitored in real time by monitoring battery temperature to ensure it remains within safe limits; ground temperature sensors can collect temperature data below the parking space to detect overheating or abnormal heat sources; and video footage from the charging station can be used to determine the presence of flames, thereby determining their area and extent of spread. Understandably, after obtaining this data, a comprehensive analysis can be performed to determine, based on preset thresholds, whether further emergency measures are needed to ensure the safety of the vehicle and the charging station environment.

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

[0056] In this embodiment, as an example, battery temperature is a key parameter for determining whether a battery is overheating or malfunctioning, especially in electric vehicles, where battery temperature changes are directly related to safety and fire risk. Higher battery temperatures indicate a higher level of accident danger. The temperature under the parking space reflects the potential spread of the fire and the intensity of the fire source. If flames come into contact with the ground or the structure under the parking space, the temperature will rise sharply, potentially causing a secondary fire. Higher temperatures under the parking space indicate a more severe fire spread and greater difficulty in controlling the fire. The flame area is a direct indicator for assessing the extent and severity of the fire. A larger flame area indicates that the fire is out of control, i.e., a higher accident level.

[0057] It should be understood that battery temperature, temperature beneath the parking space, and flame area can comprehensively reflect the rate and extent of fire spread. Higher battery temperature indicates a potential for more severe thermal runaway; increased temperature beneath the parking space suggests the fire may spread rapidly to surrounding areas; and an increased flame area directly indicates the severity of the fire. Therefore, once an alarm signal has been detected, combining these three parameters can comprehensively assess the severity, development trend, and spread rate of the fire, thereby helping to determine the accident level and enabling appropriate emergency response measures to be taken to ensure personnel safety and minimize property damage.

[0058] It should be noted that synchronous communication between the charging station and the vehicle can be achieved through Bluetooth authentication and WIFI signal. A dedicated video monitor is set up in each parking space. When the charging station receives any level of accident status, it will send the accident level to the user's mobile app and the charging station cloud platform within 1 second, and send the real-time monitoring video of the parking space. After receiving the accident status reminder, the charging station will immediately disconnect the charging gun through the charging robot and automatically send an SMS message within 1 second to call the user's mobile phone number through AI to inform them of the accident level.

[0059] Step S30: If the accident location is detected to be at the vehicle end, then control the transfer of the accident vehicle to the accident handling area and / or control the distance between the accident vehicle and the non-accident vehicle based on the accident level.

[0060] As an example, in the embodiments of this application, the accident location refers to the specific location or area where the accident occurred; the accident handling area refers to a specific area set up after an accident 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 did not directly participate in the accident.

[0061] Specifically, when a fire is detected at the vehicle end, it indicates that the accident occurred on a specific vehicle, which usually poses a significant safety risk. In this case, the affected vehicle can be moved to the accident handling area based on the severity of the accident. If the accident severity is low, indicating a lower risk at the vehicle end, the affected vehicle can be slowly moved to the accident handling area, or the distance between the affected and non-affected vehicles can be controlled to keep the affected vehicle away from the non-affected vehicles, thus ensuring the safety of the non-affected vehicles. When the accident severity is moderate, there may be risks such as sparks or battery overheating. In this case, moving the affected vehicle to the accident handling area while maintaining a certain distance between the affected and non-affected vehicles helps prevent the non-affected vehicles from entering the danger zone and avoids the risk of collision. If the accident severity is high, such as a fire or battery thermal runaway, the affected vehicle can be quickly moved to the accident handling area while maintaining a considerable distance between the affected and non-affected vehicles to effectively prevent the fire from spreading to the surrounding area, thereby ensuring the safety of the non-affected vehicles.

[0062] Step S40: If the accident location is detected to be a non-vehicle end, then control the non-accident vehicles to be transferred to safe areas in different locations based on the accident level.

[0063] In this exemplary embodiment, the non-vehicle end in the charging station refers to the facility itself, such as charging piles and electrical facilities; the safety zone refers to a special area set up after an accident to protect personnel safety and avoid secondary accidents or greater harm; specifically, the level of the accident determines the distance between the safety zone and the accident location, where the lower the accident level, the smaller the distance between the safety zone and the accident location; the higher the accident level, the larger the distance between the safety zone and the accident location, so different accident levels correspond to different safety zones; non-vehicle end accidents may not involve direct collisions between vehicles, but they can still threaten the normal operation of the charging station and vehicle safety. Therefore, if a non-vehicle end accident is detected, it is necessary to control the transfer of non-accident vehicles in a timely manner based on the accident level to ensure that non-accident vehicles are safely transferred to different safety zones to ensure the normal operation of the charging station and the safety of all vehicles.

[0064] This application, upon detecting an alarm signal, acquires the battery temperature, the temperature beneath the parking space, and the flame area. Based on these parameters, it determines the accident level and implements different protection measures for the charging station and charging vehicles accordingly. Specifically, if the accident location is detected at the vehicle end, it controls the transfer of the affected vehicle to the accident handling area and / or controls the distance between the affected vehicle and non-affected vehicles to prevent the fire or other hazards from spreading to the charging station facilities. If the accident location is detected at a non-vehicle end, it controls the transfer of non-affected vehicles to different safe areas to prevent them from entering dangerous areas while ensuring vehicle safety. By determining the accident level and detecting the accident location, this application can quickly implement appropriate emergency measures to protect the charging station and charging vehicles in the event of a safety accident, reducing losses and effectively controlling the spread of fire. This not only improves the safety of the charging station and charging vehicles but also ensures stability and reliability during the charging process.

[0065] Furthermore, in one embodiment, reference is made to Figure 2 As shown, the determination of the accident level based on battery temperature, temperature under the parking space, and flame area includes:

[0066] Step S201: If the detected 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, then the accident level is determined to be Level 1.

[0067] Step S202: If any one of the following is detected: the battery temperature is greater than a preset first temperature threshold, the temperature under the parking space is greater than a preset second temperature threshold, or the flame area is less than a preset area threshold, then the accident level is determined to be Level 2.

[0068] Step S203: If the detected flame area is greater than or equal to a preset area threshold, the accident level is determined to be Level 3, wherein the first temperature threshold is greater than the second temperature threshold, and the severity of the accident is sorted from low to high as: Level 1, Level 2, Level 3.

[0069] As an example, in the embodiments of this 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 preferably be 100°C, the preset second temperature threshold can preferably be 80°C, and the preset area threshold can preferably be 1m. 2 The severity of the accidents is ranked from lowest to highest as follows: Level 1, Level 2, and Level 3.

[0070] Specifically, if an alarm signal has been detected, and the battery temperature is ≤ a preset first temperature threshold and the temperature under the parking space is ≤ a preset second temperature threshold, it indicates a low fire risk, and the accident level can be determined as Level 1. If any one of the following conditions is detected: battery temperature > a preset first temperature threshold, temperature under the parking space > a preset second temperature threshold, or flame area < a preset area threshold, it indicates a relatively serious fire with a small flame area, and the accident level can be determined as Level 2. If the flame area is ≥ a preset area threshold, it indicates that the fire has spread to a large area, and the accident level can be determined as Level 3.

[0071] It should be understood that the embodiments of this application can accurately determine the risk level of a fire by comprehensively monitoring and evaluating the battery temperature, the temperature under the parking space, and the flame area, thereby achieving a 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 enhances the intelligence level of the system, thereby minimizing the loss and impact of the fire.

[0072] Furthermore, in one embodiment, reference is made to Figure 3 As shown, the method of controlling the transfer of accident vehicles to the accident handling area based on accident level and / or controlling the distance between accident vehicles and non-accident vehicles includes:

[0073] Step S301: If the accident level is Level 1, the accident vehicle is transferred to the preset accident handling area based on the preset vehicle relocation robot control.

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

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

[0076] As an example, in the embodiments of this 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 device that has been pre-programmed and configured 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 described in detail here for the sake of simplicity.

[0077] Specifically, after determining the accident level, the vehicle relocation robot can be controlled to perform different transfer tasks according to the accident level. If the accident level is Level 1, the severity of the fire is relatively low, and the vehicle relocation robot can be used to move the accident vehicle to the designated accident handling area or control the distance between the accident vehicle and non-accident vehicles. If the accident level is Level 2, the vehicle relocation robot can be used to move the accident vehicle to the accident handling area, and during the transfer process, the distance between the accident vehicle and surrounding non-accident vehicles must be greater than a preset first distance threshold to prevent the accident vehicle from colliding with or interfering with other vehicles. If the accident level is Level 3, the vehicle relocation robot needs to perform stricter control, that is, it must ensure that the distance between the accident vehicle and non-accident vehicles is greater than a preset second distance threshold during the transfer process, so as to effectively avoid potential safety hazards under higher risk conditions.

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

[0079] If the accident level is Level 1, the preset first speed will be used as the driving speed of the car moving robot.

[0080] If the accident level is Level 2, the preset second speed will be used as the driving speed of the car-moving robot.

[0081] If the accident level is level three, the preset third speed will be used as the driving speed of the car moving robot. The first speed, the second speed, and the third speed are ordered from smallest to largest as follows: first speed, second speed, third speed.

[0082] As an example, in the embodiments of this 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, as long as they are ordered from smallest to largest as: first speed, second speed, and third speed. There is no limitation here. For example, the preset first speed can preferably be 10 km / h, the preset second speed can preferably be 20 km / h, and the preset third speed can preferably be 30 km / h.

[0083] Specifically, in the workflow of the car-moving robot, the driving speed can be determined according to the accident level assessment. Specifically, when the accident level is Level 1, a preset first speed can be used as the robot's driving speed. This speed is usually low to ensure the stability and safety of vehicle transfer in low-risk situations. When the accident level is Level 2, a preset second speed can be used as the robot's driving speed. This speed is higher than the first speed but still within a safe and controllable range, and is used for medium-risk accident transfers. When the accident level is Level 3, a preset third speed can be used as the robot's driving speed. This speed is the highest among the three preset speeds and is used to handle high-risk transfer tasks, ensuring that the accident vehicle is quickly and effectively transferred to the designated area in emergency situations.

[0084] Understandably, by linking the driving speed of the car-moving robot to the accident level, the system can adopt the most appropriate driving speed according to different risk situations. This not only ensures the safety, stability, and efficiency of the transfer process, but also avoids resource waste and equipment damage while ensuring rapid response in emergency situations.

[0085] Furthermore, in one embodiment, the method of controlling the transfer of non-accident vehicles to safe areas at different locations based on accident level includes:

[0086] If the accident level is Level 1, then the first non-accident vehicle is controlled to be transferred to the first safe area. 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 Level 2, then control the second non-accident vehicle to be transferred to the second safe area. 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 Level 3, all non-accident vehicles will be moved to the third safety zone. The distances between the safety zones and the accident site are ordered from smallest to largest as follows: first safety zone, second safety zone, and third safety zone.

[0089] In an exemplary sense, a safety zone refers to an area used to ensure the safety of personnel and vehicles in the event of a fire or emergency. Safety zones in different locations include a first safety zone, a second safety zone, and a third safety zone. In this embodiment, the safety zones can be divided according to their distance from the accident site. The distances between the safety zones and the accident site are ordered from smallest to largest as follows: first safety zone, second safety zone, and third safety zone. For example, a first safety zone can be preferably located 20m away from the accident site, a second safety zone can be preferably located 50m away from the accident site, and a third safety zone can be preferably located 100m 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. There is no limitation here. For example, a preset first distance can be preferably 5m, and a preset second distance can be preferably 10m. The first non-accident vehicle refers to the vehicle that is closer to the accident site, for example, its distance from the accident site is 5m (i.e., the first distance), and the second non-accident vehicle refers to the vehicle that is farther from the accident site, for example, its distance from the accident site is 10m (i.e., the second distance).

[0090] Specifically, when controlling the transfer of non-accident vehicles to different safe areas, this can be achieved not only through a vehicle relocation robot but also through the vehicle's autonomous driving function. Within the workflow of either the relocation robot or the autonomous driving system, the transfer of non-accident vehicles to different safe areas can be controlled according to different accident levels. For example, if the accident level is Level 1, the first non-accident vehicle can be transferred to the first safe area; if the accident level is Level 2, the second non-accident vehicle can be transferred to the second safe area to ensure priority is given to vehicles closer to the accident site; and if the accident level is Level 3, all non-accident vehicles can be transferred to the third safe area.

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

[0092] If the number of first non-accident vehicles is less than a preset first number threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset first number.

[0093] If the number of first non-accident vehicles is not less than a preset first quantity threshold and the number of first non-accident vehicles is not greater than a preset second quantity threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset second quantity.

[0094] If the number of first non-accident vehicles is greater than the preset second number threshold, then the first non-accident vehicles are controlled to move to the first safe area based on the target route of the preset third number. The preset first number, preset second number, and preset third number are ordered from smallest to largest as follows: preset first number, preset second number, and preset third number.

[0095] In an exemplary embodiment of this application, when controlling the first non-accident vehicle to move to the first safe area, the correspondence between the quantity threshold range and the target route can be set first, and then the target route can be determined by combining the relationship between the number of the first non-accident vehicles and the preset quantity threshold range. Then, the first non-accident vehicle can be controlled to move to the first safe area according to the target route.

[0096] 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. It is only necessary to satisfy that the preset first quantity threshold is less than the preset second quantity threshold and that the preset first quantity, the preset second quantity, and the preset third quantity are ordered from smallest to largest as: preset first quantity, preset second quantity, preset third quantity. There are no restrictions here. The target route refers to the route that is closest to the safe area. For example, the preset first quantity threshold can be preferably 2, and the preset second quantity threshold can be preferably 4. Then the quantity threshold range includes (0, 2), [2, 4], [4, +∞). For example, the preset first quantity can be preferably 1 (i.e., there is 1 target route), the preset second quantity can be preferably 2 (i.e., there are 2 target routes), and the preset third quantity can be preferably 3 (i.e., there are 3 target routes).

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

[0098] It is understandable that when controlling the transfer of the second non-accident vehicle to the second safe area, the correspondence between the quantity threshold range and the target route can be set first. Then, the target route can be determined by combining the relationship between the number of the second non-accident vehicles and the preset quantity threshold range. Then, the transfer of the second non-accident vehicles to the second safe area can be controlled according to the target route. Specifically, assuming that when the quantity threshold range of the second non-accident vehicles is (0, 3), there is 1 target route; when the quantity threshold range of the second non-accident vehicles is [3, 9], there are 3 target routes and the 3 routes have no intersection within 10 meters of the charging station; when the quantity threshold range of the second non-accident vehicles is (9, ∞), there are 4 target routes and the 4 routes have no intersection within 10 meters of the charging station; then, if the number of the second non-accident vehicles is 6, it meets the condition that the number of the second non-accident vehicles is within the interval [3, 9]. Therefore, there are 3 target routes, and the transfer of the second non-accident vehicles to the second safe area can be controlled according to these 3 target routes.

[0099] It should be noted that when the accident level is level 3, the number of target routes should be greater than or equal to the maximum number of target routes in the first two levels. Therefore, it is preferable to plan 4 target routes (i.e., 4 shortest routes) using a preset planning algorithm, and control all non-accident vehicles to transfer to the third safe area based on these 4 shortest 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 simplicity.

[0100] This application, upon detecting an alarm signal, acquires the battery temperature, the temperature beneath the parking space, and the flame area. Based on these parameters, it determines the accident level and implements different protection measures for the charging station and charging vehicles accordingly. Specifically, if the accident location is detected at the vehicle end, it controls the transfer of the affected vehicle to the accident handling area and / or controls the distance between the affected vehicle and non-affected vehicles to prevent the fire or other hazards from spreading to the charging station facilities. If the accident location is detected at a non-vehicle end, it controls the transfer of non-affected vehicles to different safe areas to prevent them from entering dangerous areas while ensuring vehicle safety. By determining the accident level and detecting the accident location, this application can quickly implement appropriate emergency measures to protect the charging station and charging vehicles in the event of a safety accident, reducing losses and effectively controlling the spread of fire. This not only improves the safety of the charging station and charging vehicles but also ensures stability and reliability during the charging process.

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.

[0122] If the accident level is Level 3, all non-accident vehicles will be moved to the third safety zone. The distances between the safety zones and the accident site are ordered from smallest to largest as follows: first safety zone, second safety zone, and third safety zone.
