[0059] Optionally, the liquid cooling device may be equipped with an electrically controlled throttle valve.

[0060] Specifically, when the fire probability value calculated based on the environmental detection data is greater than a preset threshold, the environmental state can be determined to be a fire state. The control terminal or server of the charging device can forcibly control the cutting off of the charging power supply, end the charging process, and stop the current output; stop the operation of the liquid cooling device and cut off the liquid cooling source, and then close the electronically controlled throttle valve and cut off the wire connection between the mobile body and the charging gun.

[0062] Among them, the area where the mobile subject is located needs to be divided.

[0063] Specifically, the control terminal or server of the mobile subject can obtain the current position according to the second acquisition device, divide the current area according to the stored preset map based on the environmental detection data, select the area with the first comprehensive ranking to determine the safe position, and plan the moving path based on the current position and the safe position.

[0064] S104: driving the moving device to move the moving body to a safe position according to the moving path.

[0065] Among them, the mobile body will release fire extinguishing spray through the fire extinguishing device during the movement.

[0066] Specifically, the control terminal or server of the charging device can control the mobile body to a safe position based on the above-mentioned planned moving path, and release a fire extinguishing spray during movement, such as a spray of dry powder or carbon dioxide.

[0067] The control method, device, charging device and storage medium of the charging device provided by the present application can obtain the environmental status through environmental detection data; when the environmental status is a fire state, the power supply of the charging device and the liquid cooling source of the liquid cooling device are cut off, and the line connection between the mobile body of the charging device and the charging gun is cut off; the current position of the mobile body is obtained, and a safe position is determined according to the environmental detection data, and then a moving path is planned based on the current position and the safe position; the charging device is controlled to move to a safe position according to the moving path. The present application can comprehensively judge the fire probability of the current environment through environmental detection data and then obtain the environmental status. When the environmental status is a fire state, an arm breaking operation is performed, and the device moves to a safe position along the planned safe path, thereby realizing protection for the charging device. In this way, the spread of fire after the battery fire can be avoided, thereby reducing damage to the charging device caused by the fire.

[0068] In an embodiment of the present application, a possible implementation method is provided, wherein the environmental status is obtained based on the environmental detection data, including:

[0069] S201, calculating the target fire probability based on the environmental detection data.

[0070] Specifically, at least one of the image information, temperature information, and smoke concentration information can be input into a pre-trained machine learning model to obtain the fire probability output by the machine learning model. The machine learning model can be a supervised learning model such as a neural network, linear regression, or logistic regression, or an unsupervised learning model such as a clustering model or a dimensionality reduction mapping model, and is not specifically limited in the present embodiments.

[0071] S202: Determine the environmental state according to the ratio of the fire probability to a preset threshold.

[0072] The environmental status includes normal status and fire status.

[0073] Specifically, when the probability of fire is less than or equal to a preset threshold, the environmental state is determined to be a normal state; when the probability of fire is greater than the preset threshold, the environmental state is determined to be a fire state; further, the preset threshold can be obtained in advance by repeated multiple tests and calculated using a model.

[0074] After obtaining environmental detection data, the embodiment of the present application calculates the fire probability through a machine learning model, and determines the environmental state based on the ratio of the fire probability to a preset threshold, which can quickly and effectively judge the current environmental state.

[0075] A possible implementation method is provided in an embodiment of the present application, where the environmental detection data includes at least one of image information, temperature information, and smoke concentration.

[0076] The environmental detection data is acquired by a first acquisition device.

[0077] Optionally, the first acquisition device may be configured with a camera, an infrared thermal imager, or a smoke detection device.

[0078] Specifically, the environmental detection data is obtained by the first acquisition device. For example, the control terminal or server of the charging device can obtain image information of the environment in which the charging device is located using a camera, obtain temperature information of the charging device using an infrared thermal imager, and obtain smoke concentration information of the environment around the charging device using a smoke detection device.

[0079] In the embodiment of the present application, by combining temperature information, image information and smoke concentration, fire events can be predicted from different dimensions, effectively improving the accuracy of fire probability.

[0080] In an embodiment of the present application, a possible implementation method is provided. The above-mentioned calculation of the target fire probability based on the environmental detection data includes at least one of the following methods:

[0081] S301, performing feature recognition on the image information to obtain a first fire probability, and determining the target fire probability based at least on the first fire probability.

[0082] Specifically, the charging device control terminal or server can extract feature information from the image information, and then identify the first fire probability based on the feature information, and can determine the fire probability based on the first fire probability.

[0083] S302 : Determine a second fire probability according to a difference between a preset temperature threshold and the temperature information, and determine the target fire probability based at least on the second fire probability.

[0084] Optionally, a correlation between temperature and fire probability may be pre-established, and the second fire probability corresponding to the temperature information may be determined based on the correlation.

[0085] S303: Determine a third fire probability according to a difference between a preset smoke density threshold and the smoke density, and determine a target fire probability based at least on the third fire probability.

[0086] Optionally, a correlation between smoke concentration and fire probability may be pre-established, and the third fire probability corresponding to the smoke concentration may be determined based on the correlation.

[0087] Furthermore, different weights can be assigned to the first, second, and third fire probabilities in the target fire probability. Assuming the output first fire probability is T, the second fire probability is H, and the third fire probability is W, the image recognition method fire weight is defined as Y1, the thermal imaging method as Y2, and the smoke detection device as Y3. The target fire probability is P. The target fire probability is calculated as follows: P = Y1 * T + Y2 * H + Y3 * W.

[0088] After obtaining the environmental detection data, the embodiment of the present application calculates the total fire probability according to the fire probability output by the machine learning model and the pre-set weight value. The present application predicts the fire probability from multiple different dimensions such as image, temperature and smoke concentration, effectively enhancing the accuracy of the probability calculation.

[0089] A possible implementation method is provided in an embodiment of the present application, wherein the liquid cooling device further includes an electrically controlled throttle valve;

[0090] After cutting off the power output of the charging device and the liquid cooling source output of the liquid cooling device, including:

[0091] Send a command to the electronically controlled throttle valve to close the electronically controlled throttle valve and cut off the coolant.

[0092] In the embodiment of the present application, the coolant can be cut off by an electronically controlled throttle valve to prevent leakage of residual coolant in the liquid cooling pipe during the process of cutting off the wire connection between the main body and the charging gun.

[0093] The present application provides a possible implementation method for determining a safe location based on environmental detection data, including:

[0094] S401: Divide the area where the charging device is located into multiple sub-areas based on a preset environment map.

[0095] The charging device control terminal or server may update the environment map according to a preset frequency based on the collected image information.

[0096] Specifically, the charging device can be divided into nine sub-areas of equal size based on the latest environmental map and the current location.

[0097] S402: Determine a fourth fire probability for each sub-area based on the environmental detection data.

[0098] Specifically, the environmental detection sub-data of each sub-area may be acquired according to the location information carried by the environmental detection data, and the fourth fire probability of each sub-area may be determined based on the environmental detection sub-data.

[0099] In the embodiment of the present application, the method of determining the fire probability based on the environmental detection sub-data can be the same as the method of calculating the fire probability above, and will not be repeated here.

[0100] S403: Arrange the sub-regions in ascending order according to the fourth fire probability of each sub-region, and select the sub-region ranked first as the safe location.

[0101] Specifically, the areas are sorted in ascending order according to the fourth fire probability of each divided sub-area. If sub-areas with the same fire probability are encountered, they are sorted in ascending order according to the distance from the current location, and the sub-area ranked first is selected as the safe location.

[0102] After obtaining the environmental detection data, the embodiment of the present application divides the area according to the preset map and calculates the fire probability of each sub-area, and selects the first one in ascending order as the safe location. In this way, the safe location can be accurately determined and the probability of the charging equipment being damaged by fire is reduced.

[0103] A possible implementation method is provided in an embodiment of the present application, where the mobile body may include a fire extinguishing device.

[0104] After planning the movement path based on the current position and the safe position, the following steps are included:

[0105] During the process of driving the mobile device to move, the fire extinguishing device is controlled to release the fire extinguishing spray.

[0106] Optionally, the fire extinguishing spray may be a spray of dry powder or carbon dioxide.

[0107] Specifically, after the mobile entity plans a moving path based on its current position and a safe position, the control terminal or server of the charging device releases a fire-extinguishing spray while moving toward the safe position. For example, the control terminal or server of the charging device can control the release of dry powder or carbon dioxide and other sprays that can extinguish fires.

[0108] In the embodiment of the present application, when the charging device is moving toward a safe location, the fire extinguishing device is controlled to release the fire extinguishing spray, which can effectively reduce the probability of fire in the charging device.

[0109] In order to better understand the control method of the above charging device, Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8An example of a control method for a charging device of the present application is described in detail. The charging device may include a controller, a charging device, a liquid cooling device, a fire extinguishing device, a charging gun, a moving device, a first acquisition device, a second acquisition device, and an actuator.

[0110] The method comprises the following steps:

[0111] S501: When the charging device is charging, the first obtaining device senses the surrounding environment of the charging device in real time, obtains environmental information, and detects and determines sudden battery fire.

[0112] The environmental information includes image information, temperature information, and smoke concentration information.

[0113] Specifically, the above environmental information is acquired by a first acquisition device consisting of a camera, an infrared thermal imager, and a smoke detector. The camera monitors the area surrounding the charging station in real time. By pre-training deep learning on fire images or videos, it extracts feature information from the images, determines whether a fire is occurring in the area surrounding the fire, and outputs a fire probability T. The infrared thermal imager monitors temperature and outputs a fire probability H when the temperature reaches or approaches a set threshold. The smoke detector detects the particle concentration in the air at the time of the fire and outputs a fire probability W. The image recognition method fire weight is defined as Y1, the thermal imager recognition method weight as Y2, and the smoke detector recognition method weight as Y3, with the overall fire probability as P. The fire probability is calculated as follows: P = T * Y1 + H * Y2 + W * Y3. With a threshold of 0 < M < 1, when P ≥ M, a fire is detected; when P < M, no fire is detected.

[0114] S502, when it is determined that a fire has occurred, the controller sends a command to the charging device and the liquid cooling device to control the cutting off of the charging power supply and the liquid cooling source;

[0115] Specifically, the liquid cooling device includes an electrically controlled throttle valve. When a fire is determined, the controller can send instructions to the charging device and the liquid cooling device to forcibly control the cutting off of the charging power supply, end the charging process, and stop the current output; stop the operation of the liquid cooling device, and then forcibly control the cutting off of the liquid cooling source through the liquid cooling throttle valve.

[0116] S503, after cutting off the charging power supply and the liquid cooling source, the controller sends a command to the actuator to control the actuator to automatically remove the charging gun cable.

[0117] Specifically, the actuator includes an electronically controlled throttle valve, an electronic lock, and a free telescopic device. The controller sends instructions to the charging gun wire connection part to close the electronically controlled throttle valve at the charging device socket, which can prevent the residual coolant in the liquid cooling pipe from leaking out during the "arm breaking" process; it drives the electronic lock to unlock the charging robot socket part. Since the charging gun wire is connected in a plug-in manner, when the electronic lock is unlocked, the arm breaking conditions are met. It only needs to receive an axial force in the plug-in direction to control the free telescopic device to drive the boss to extend to achieve arm breaking.

[0118] like Figure 5 As shown, the liquid cooling throttle valve 501 is located at the outlet 502 of the cooling pipe at the charging device end and the inlet 503 of the cooling pipe at the charging device end.

[0119] Furthermore, the inlet and outlet of the liquid cooling pipe can be directly connected using a flange quick-connect plug 505, and the plug-in part is clamped by a controllable fastening mechanical clamping device 504 to ensure the effectiveness of the cooling pipe connection. It can also move axially and has the ability to automatically unplug the cooling pipe. The liquid cooling throttle valve can be electrically controlled. According to the liquid cooling circuit principle diagram, as shown in FIG. Figure 4 As shown, it can open and cut off the coolant.

[0120] like Figure 6 As shown, the actuator is located at the connection position between the charging cable 602 and the charging device 601 .

[0121] like Figure 7 、 8 As shown, the electronic lock includes an electronic lock locking device 701 located at the charging device end and an electronic lock interface 801 located at the charging cable end. The free extension device 702 is on both sides of the charging device end interface, which can control the free extension and contraction of the boss to disconnect the charging cable from the charging device.

[0122] S504: Find a safe location and perform path planning.

[0123] Specifically, the area where the charging equipment is located is divided into multiple sub-areas based on a preset environmental map. The fire probability of each sub-area is determined based on the environmental detection data, and the sub-areas are arranged in ascending order. The sub-area ranked first is selected as the safe position. The controller analyzes and formulates a safe escape route based on the safe position and the starting position.

[0124] S505: Move to a safe location according to the planned path, and release fire extinguishing spray during the movement.

[0125] Specifically, the controller controls the mobile device of the charging device to move according to the planned path and move to a safe position. During the movement, the controller controls the fire extinguishing device to release a fire extinguishing spray, such as a spray of dry powder or carbon dioxide.

[0126] The embodiment of the present application provides a control device for a charging device, such as Figure 9 As shown, the control device 90 of the charging device may include: a judgment module 901, a cut-off module 902, a planning module 903 and a moving module 904;

[0127] The judgment module 901 is used to obtain the environmental status based on the environmental detection data during the charging process;

[0129] Planning module 903, used to determine a safe location based on environmental detection data and plan a movement path based on the current location and the safe location;

[0130] The moving module 904 is used to control the moving device to move the moving body to a safe position according to the moving path.
