It should be understood that the terms used in this way can be interchanged under appropriate circumstances, which is only a way of distinguishing objects with the same properties in the description of the embodiments of the present application.

[0082] Figure 1 is a schematic diagram of the main process of the charging gun line state detection method according to an embodiment of the present application, as shown in Figure 1 The charging gun line state detection method mainly includes the following steps S101-S103.

[0083] Step S101, in response to detecting a user within a predetermined range of the charging pile, determining the angle difference between the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line.

[0084] In the present embodiment, the implementation of the charging gun line detection method at least involves a charging pile (for example, 401 in Figure 4 ) and a charging pile main control board (for example, 402 in Figure 4 ), and the charging gun line (for example, 401 in Figure 4 ) is connected to the charging pile (for example, 401 in Figure 4 ), which can include the first pose sensor 406, the cable 403, the charging gun 405, the second pose sensor 407 as a whole assembly, two pose sensors are integrated in the charging gun line, which are the first pose sensor (for example, 404 in Figure 4 ) integrated in the cable tail (for example, 404 in Figure 4406 in the middle), and the charging gun integrated into the charging gun cable connected to it (e.g., Figure 4 The second pose sensor (e.g., 405) in the middle) Figure 4 (407 in the middle).

[0085] In this embodiment, when the execution subject of the charging gun line status detection method (for example, it can be the charging pile main control board, or it can be a server that is communicatively connected to the charging pile main control board) is in such a state as Figure 4 When a user is detected within a preset range of the charging pile 401 (e.g., a circular area with a radius of 1m centered on the location of the charging pile 401), the cable tail of the charging gun line (i.e., the charging gun line connected to the charging pile) corresponding to the charging pile 401 can be determined first (e.g., Figure 4 404 in the middle) and the charging gun connected to the charging gun line (e.g., Figure 5 The angle difference (405) is the absolute value of the angle difference between the end of the charging gun cable and the charging gun.

[0086] Specifically, in order to detect users within a preset range of the charging pile, the charging gun status detection method may further include: acquiring environmental information detected by a camera device and / or infrared sensor installed at the charging pile. For example, the camera device may be a webcam, and the environmental information may include environmental images, environmental video streams, etc., such as user activity information and dynamic obstacle activity information. The dynamic obstacle may be an animal, a moving vehicle, etc. Based on the environmental information, detecting whether a user is present within the preset range of the charging pile. For example, determining whether the location of the user in the detected environmental information is within the preset range of the charging pile. If the user is within the preset range, it is determined that a user is present within the preset range of the charging pile; if not, it is determined that no user is present within the preset range of the charging pile. This allows for real-time detection of whether a user is present within the preset range of the charging pile.

[0087] For a server that is connected to the main control board of the charging pile as the executing entity, the environmental information detected by the camera and / or infrared sensor of the charging pile can be provided directly to the server via communication, or the camera and / or infrared sensor can provide the environmental information to the main control board of the charging pile, and the main control board of the charging pile can provide the environmental information to the server via communication.

[0088] Step S102: Generate a level signal indicating the status of the charging gun cable based on the angle difference.

[0089] like Figure 2As shown, the server 501 corresponding to the charging pile mainboard (for example, a micro control unit MCU) generates a level signal 502 indicating the state of the charging gun line according to the angle difference value between the cable tail of the charging gun line and the charging gun connected by the charging gun line based on the preset angle difference value and the corresponding relationship of the level signal. If the level signal 502 is a high level signal K1, it indicates that the state of the charging gun line is a twisted state 503, and a safety prompt is triggered for the user; if the level signal 502 is a low level signal K2, it indicates that the state of the charging gun line is an untwisted state, and the charging gun line state detection 505 is ended this time.

[0090] Step S103, in the case that the level signal indicates that the state of the charging gun line is a twisted state, a safety prompt is triggered for the user.

[0091] In some embodiments, when the level signal generated according to the angle difference value is a high level signal, it indicates that the state of the charging gun line is a twisted state, and a trigger instruction is generated and provided to the loudspeaker to make the loudspeaker timely give a safety prompt to the user according to the trigger instruction.

[0092] In some embodiments, triggering a safety prompt for the user includes: outputting a level signal (which is a high level signal) indicating that the state of the charging gun line is a twisted state to a safety prompt system, so that the safety prompt system gives a voice prompt through the loudspeaker to timely give a safety prompt to the user.

[0093] In the embodiments of the present application, the execution subject determines the angle difference value between the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line in response to detecting the user within the preset range of the charging pile; generates a level signal indicating the state of the charging gun line according to the angle difference value; and triggers a safety prompt for the user in the case that the level signal indicates that the state of the charging gun line is a twisted state. The charging gun line can be accurately identified as twisted, and the user can be timely reminded of the safety risk caused by the twisted charging gun line to prevent the user from being injured by the rebound force of the twisted charging gun line.

[0094] Figure 2 FIG. 1 is a main flow diagram of a charging gun line state detection method according to an embodiment of the present application, as shown in the figure, the charging gun line state detection method mainly includes the following steps S201-S204. Figure 4

[0095] In the present application, the cable tail of the charging gun line (for example, 404 in FIG. 4) is provided with a first pose sensor (for example, 406 in FIG. 4), and the charging gun (for example, 405 in FIG. 4) connected by the charging gun line is provided with a second pose sensor (for example, 406 in FIG. 4). Figure 4 Figure 4 Figure 4 Figure 3 ​​​​in the 407).

[0096] In step S201, in response to detecting the user within the preset range of the charging pile, a first azimuth angle of the cable tail detected by the first pose sensor in real time and a second azimuth angle of the charging gun detected by the second pose sensor in real time are acquired.

[0097] When the user is detected within the preset range of the charging pile, the first azimuth angle of the cable tail detected by the first pose sensor integrated (or arranged) in the cable tail of the charging gun line in real time is acquired to accurately represent the orientation of the cable tail, and the second azimuth angle of the charging gun detected by the second pose sensor integrated (or arranged) in the charging gun connected by the charging gun line in real time is acquired to accurately represent the orientation of the charging gun.

[0098] In step S202, according to the first azimuth angle and the second azimuth angle, an angle difference between the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line is determined.

[0099] The absolute value of the difference between the first azimuth angle and the second azimuth angle is determined as the angle difference between the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line, that is, the angle difference = |first azimuth angle-second azimuth angle|.

[0100] Preferably, the first pose sensor and the second pose sensor are integrated in the charging gun line. The charging gun line is an integral assembly, and the two pose sensors are integrated in the cable tail and the charging gun. The absolute value of the difference between the azimuth angles measured by the two pose sensors (that is, the angle difference) is used to accurately determine whether the charging gun line is twisted.

[0101] In step S203, according to the angle difference, a level signal indicating the state of the charging gun line is generated.

[0102] In step S204, in the case that the level signal indicates that the state of the charging gun line is a twisted state, a safety prompt is triggered to the user.

[0103] In the present application, the server corresponding to the charging pile mainboard (for example, a micro control unit MCU) determines the angle difference between the two pose sensors integrated in the cable tail and the charging gun through the pose parameter information of the charging gun line, and then accurately determines whether the charging gun line is twisted and whether to perform a safety prompt to the user. When the charging gun line is not twisted, the MCU outputs a low-level signal; when the charging gun line is twisted, the MCU outputs a high-level signal, and timely performs a safety prompt to the user to prevent the user from being injured by the rebound force of the twisted charging gun line.

[0104] Figure 3 FIG. 1 is a main flowchart of a charging gun line state detection method according to an embodiment of the present application, as shown in Figure 6As shown, the charging gun line state detection method mainly includes the following steps S301-S304.

[0105] Step S301, in response to detecting a user within a preset range of the charging pile, determining the angle difference value of the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line.

[0106] Step S302, determining the outlet position and the gun hanging position of the charging gun line set by the charging pile, and the outlet position coincides with the cable tail of the charging gun line.

[0107] The relative positional relationship of the outlet position and the gun hanging position of the charging gun line set by the charging pile (wherein the outlet position coincides with the cable tail of the charging gun line) is different in structure.

[0108] Exemplarily, in some embodiments, as Figure 7 As shown, the charging pile 401 is provided with the outlet position 601 and the gun hanging position 602 of the charging gun line, and the outlet position 601 and the gun hanging position 602 are located on the same side of the charging pile 401, and the outlet position 601 coincides with the cable tail 404 of the charging gun line.

[0109] In some embodiments, as Figure 8 As shown, the charging pile 401 is provided with the outlet position 601 and the gun hanging position 602 of the charging gun line, and the outlet position 601 and the gun hanging position 602 are located on the opposite sides of the charging pile 401, and the outlet position 601 coincides with the cable tail 404 of the charging gun line.

[0110] In some embodiments, as Figure 6 As shown, the charging pile 401 is provided with the outlet position 601 and the gun hanging position 602 of the charging gun line, and the outlet position 601 and the gun hanging position 602 are located on the adjacent sides of the charging pile 401, and the outlet position 601 coincides with the cable tail 404 of the charging gun line.

[0111] Step S303, according to the outlet position and the gun hanging position, determining the angle difference threshold value, and based on the angle difference value and the angle difference threshold value, generating a level signal indicating the state of the charging gun line.

[0112] In this application, the angle difference value is an absolute value, that is, it is impossible to be negative. When the charging gun is hung on the gun hanging position set by the charging pile, the charging gun line is in an untwisted state, and when the charging gun is not hung on the gun hanging position set by the charging pile but is placed randomly on the charging pile or in a position around the charging pile which is different from the gun hanging position, the charging gun line is in a twisted state. Specifically, according to the outlet position and the gun hanging position, the angle difference threshold value is determined, and based on the angle difference value and the angle difference threshold value, a level signal indicating the state of the charging gun line is generated, including: in the case that the outlet position and the gun hanging position are located on the same side of the charging pile, that is, as Figure 7In the case of the outlet position 601 and the gun hanging position 602 as shown, if the orientations of the two pose sensors integrated in the cable tail and the charging gun are consistent, the angle difference threshold is determined as 0°, a high-level signal (for example, 1) indicating the twisted state is generated in response to the angle difference value being greater than 0° (it can also be understood that the angle difference value is not equal to 0° but also not less than 0°), and a low-level signal (for example, 0) indicating the untwisted state is generated in response to the angle difference value being equal to 0°. Figure 8 In the case of the outlet position 601 and the gun hanging position 602 as shown, if the orientations of the two pose sensors integrated in the cable tail and the charging gun are opposite, the angle difference threshold is determined as 180°, a high-level signal (for example, 1) indicating the twisted state is generated in response to the angle difference value being less than 180° (it can also be understood that the angle difference value is not equal to 180°, that is, 0°≤ the angle difference value < 180°), and a low-level signal (for example, 0) indicating the untwisted state is generated in response to the angle difference value being equal to 180°; it can be understood that in the present application, the angle difference value will not be greater than 180°. In the case of the outlet position and the gun hanging position being located on the adjacent side of the charging pile, that is, as shown in Figure 10 In the case of the outlet position 601 and the gun hanging position 602 as shown, if the orientations of the two pose sensors integrated in the cable tail and the charging gun are opposite, the angle difference threshold is determined as 180°, a high-level signal (for example, 1) indicating the twisted state is generated in response to the angle difference value being less than 180° (it can also be understood that the angle difference value is not equal to 180°, that is, 0°≤ the angle difference value < 180°), and a low-level signal (for example, 0) indicating the untwisted state is generated in response to the angle difference value being equal to 180°; it can be understood that in the present application, the angle difference value will not be greater than 180°. In the case of the outlet position and the gun hanging position being located on the adjacent side of the charging pile, that is, as shown in

[0113] In step S304, in the case that the level signal indicates that the state of the charging gun line is the twisted state, a safety prompt to the user is triggered.

[0114] The angle difference value between the cable tail of the charging gun line corresponding to the charging pile and the charging gun connected by the charging gun line can be accurately judged whether the charging gun line connected with the charging pile is twisted or not, and a safety prompt to the user is given in time when the charging gun line is twisted, so as to prevent the charging user from being injured by the rebound force of the twisted charging gun line.

[0115] Figure 10 It is a schematic diagram of the main unit of the charging gun line state detection device according to the embodiments of the present application. As shown in Figure 10 The charging gun line state detection device 1000 includes an angle difference value determination unit 1001, a level signal generation unit 1002, and a safety prompt unit 1003.

[0116] The angle difference determining unit 1001 is configured to determine an angle difference between the cable tail of the charging gun cable corresponding to the charging pile and the charging gun connected by the charging gun cable in response to detecting the user within the preset range of the charging pile.
