[0068] In an embodiment of the present application, a possible implementation method is provided, wherein the environmental state 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 probability of fire 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, which is not specifically limited in the embodiments of the present application.

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

[0072] Among them, 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 acquiring the environmental detection data, the embodiment of the present application calculates the fire probability through a machine learning model, and determines the environmental state according to the ratio of the fire probability to a preset threshold, so as to 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 based on a camera, obtain temperature information of the charging device based on an infrared thermal imager, and obtain smoke concentration information of the surrounding environment of the charging device through 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 the 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 at least based on the second fire probability.

[0084] Optionally, a correlation relationship between temperature and fire probability may be pre-constructed, and the second fire probability corresponding to the temperature information may be determined according to the correlation relationship.

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

[0086] Optionally, a correlation relationship between smoke concentration and fire probability may be pre-constructed, and a third fire probability corresponding to the smoke concentration may be determined according to the correlation relationship.

[0087] Furthermore, different weights can be set for the proportions of the first fire probability, the second fire probability, and the third fire probability in the target fire probability. It can be assumed that the output first fire probability is T, the second fire probability is H, and the third fire probability is W, and the image recognition method fire weight is defined as Y1, the thermal imager recognition method weight is Y2, the smoke detection device recognition method weight is Y3, and the target fire probability is P. The target fire probability is calculated as follows: P = Y1*T+Y2*H+Y3*W.

[0088] After acquiring 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:

[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] In an embodiment of the present application, a possible implementation method is provided to determine a safe location based on environmental detection data, including:

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

[0095] Among them, the charging device control terminal or server can update the environmental map according to a preset frequency based on the collected image information.

[0096] Specifically, the charging device can divide the area into 9 sub-areas of equal size based on the current location according to the latest environmental map.

[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 described above, and will not be repeated here.

[0100] S403, according to the fourth fire probability of each sub-region, the sub-regions are arranged in ascending order, and the sub-region ranked first is selected as the safe position.

[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 between the area and the current position, and the sub-area ranked first is selected as the safe position.

[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 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, and the mobile body may include a fire extinguishing device.

[0104] After planning the moving path based on the current position and the safe position, it includes:

[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 the current position and the safe position, while moving toward the safe position, the control terminal or server of the charging device releases a fire-extinguishing spray. 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 position, 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 acquisition device senses the surrounding environment of the charging device in real time, acquires 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 obtained by the first acquisition device composed of a camera, an infrared thermal imager, and a smoke detection device: the camera monitors the surroundings of the charging station in real time, extracts feature information from the image by deep learning of fire pictures or videos in advance, and determines whether the surroundings of the fire are on fire, and outputs the probability of fire T; the infrared thermal imager monitors the temperature, and outputs the probability of fire H when the temperature reaches or approaches the set threshold; the smoke detection device outputs the probability of fire W by detecting the particle concentration in the air at the time of fire. Define the fire weight of the image recognition method as Y1, the weight of the thermal imager recognition method as Y2, the weight of the smoke detection device recognition method as Y3, and the overall probability of fire as P. The probability of fire is calculated as follows: P = T*Y1+H*Y2+W*Y3, set the threshold 0<M<1, when P≥M, it is judged as a fire, and when P<M, it is judged as no fire.

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

[0115] Specifically, the liquid cooling device includes a flow-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 line.

[0117] Specifically, the actuator includes an electronically controlled throttle valve, an electronic lock, and a free telescopic device. The controller sends a command to the charging gun line connection part to close the electronically controlled throttle valve at the charging device socket to prevent the residual coolant in the liquid cooling pipe from leaking out during the "arm breaking" process; it drives the electronic lock at the socket part of the charging robot to unlock. Since the charging gun line 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 positions of the liquid cooling pipe can be directly connected by 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, and can move axially and have the ability to automatically unplug the cooling pipe. The liquid cooling throttle valve can be electrically controlled, according to the schematic diagram of the liquid cooling circuit principle, as shown in FIG. Figure 4 As shown, it can play the role of opening and cutting 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 located on both sides of the charging device end interface, which can control the free extension and retraction 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 escape process, the controller controls the fire extinguishing device to release a fire extinguishing spray, such as a spray of dry powder or carbon dioxide.
