The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0022] See also Figure 1 , Figure 1 is a block diagram of a target charging pile according to an exemplary embodiment. Figure 1 As shown, the target charging pile may include a controller, a first communication module, a gun line corresponding to the target charging pile, a sensor module, an alarm module and a video acquisition device. Among them, the controller can be used to implement the above-mentioned abnormality detection method. The first communication module can be used to realize the reception or transmission of data, such as abnormal prompt signals, real-time gun line environment video or recorded gun line environment video; specifically, the first communication module can realize data transmission through wireless signals. The alarm module may include an audible and visual alarm. The video acquisition device can be used to realize the video data acquisition of the gun line of the target charging pile and its surrounding environment. The video acquisition device can adopt 1080P resolution, support night vision and wide-angle shooting, be installed on the top of the target charging pile, cover the gun line and the surrounding area; the storage device of the video acquisition device uses a 64GB SD card to support loop recording. Furthermore, the gun line corresponding to the target charging pile can be provided with a sensor module; the sensor module can be used to realize the collection and data transmission of the current gun line status data of the charging pile gun line. The sensor module can be set in the gun line of the target charging pile. The sensor module may include a built-in communication unit; the built-in communication unit may be used to transmit the collected current gun line state data to the first communication module of the target charging pile, so that the current gun line state data may be transmitted to the controller of the target charging pile through the first communication module. Specifically, the communication unit and the first communication module may communicate through wired signals or wireless signals. Optionally, when the wired communication between the communication unit and the first communication module is disconnected, the communication between the two may be achieved through wireless signals.

[0023] In a specific embodiment, the sensor module may include a first sensor submodule and a plurality of second sensor submodules. The first sensor submodule may be arranged at a charging gun corresponding to a target charging pile; a plurality of second sensor submodules may be respectively arranged at different positions of a charging cable corresponding to a target charging pile. Among them, the first sensor submodule may include a pressure sensor, a displacement sensor and an acceleration sensor; any second sensor submodule may include one or more of a pressure sensor, a displacement sensor and an acceleration sensor. Exemplarily, the number of second sensor submodules may be at least three, wherein two second sensor submodules may be arranged at both ends of a charging cable, and the remaining second sensor submodules may be arranged in the middle of a charging cable, and the cable cross-section position where each second sensor submodule is arranged is different. Furthermore, each sensor may have a built-in communication unit; each sensor may send data through the communication unit.

[0024] In the above embodiment, by setting the above sensor module on the gun line, and multiple sensor sub-modules in the sensor module can be set at different positions in the gun line, the pressure data, acceleration data and displacement data at different positions of the gun line can be collected, thereby improving the accuracy of abnormal identification of the target charging pile gun line.

[0025] In a specific embodiment, the target charging pile may include a charging gun backup power supply, and the backup power supply may be arranged in the charging gun of the target charging pile. The charging gun backup power supply may be used to realize the power supply of the sensor module when the target charging pile disconnects the power supply to the charging gun. Among them, the charging gun backup power supply may be electrically connected to the sensor module. Specifically, when the cable of the charging pile is normally powered on (i.e., there is no abnormality such as the cable being cut), the charging pile may supply power to the sensor module in the charging gun, and the charging gun backup power supply may not supply power (such as the switch between the charging gun backup power supply and the sensor module is disconnected); when the cable of the charging pile cannot be powered on normally (such as the cable being cut), that is, the charging pile cannot supply power to the sensor module at this time, the charging gun backup power supply may be used to supply power (when the power supply of the charging gun is detected to be disconnected, the switch between the charging gun backup power supply and the sensor module may be controlled to be closed so that the charging gun backup power supply supplies power to the sensor module).

[0026] In a specific embodiment, a normally closed relay is provided between the charging gun backup power supply and the sensor module; the charging pile can output a control signal through a charging cable and connect it to the coil of the relay; when the charging pile is powered normally through the charging cable, the coil of the relay is energized and the relay is disconnected; when the charging cable of the charging pile is disconnected and cannot supply power normally, the coil of the relay is not energized, the relay is closed, and the charging gun backup power supply can supply power to the sensor module.

[0027] In a specific embodiment, when the disconnect position of the charging cable is between any two sensor sub-modules, the charging gun backup power supply can supply power to at least one sensor sub-module in the charging cable segment connected to the charging gun; when there is at least one sensor sub-module in the charging cable segment connected to the target charging pile, the target charging pile can supply power to at least one sensor sub-module in the charging cable segment connected to the target charging pile.

[0028] In the above embodiment, by arranging a charging gun backup power supply in the charging gun, it is possible to power the sensor in the cable segment connected to the charging gun after the charging cable is cut off, and to collect pressure data, acceleration data and displacement data for the cable segment connected to the charging gun, thereby improving the accuracy of identifying gun line abnormalities of the target charging gun.

[0029] In a specific embodiment, Figure 1 As shown, the target charging pile may also include a locking mechanism. The locking mechanism may be used to prevent the user from unplugging the gun line of the target charging column without authorization; the locking mechanism may include an electromagnetic lock or a mechanical lock. It is understandable that there are some charging piles that may have a locking mechanism (such as public charging piles, etc.), and there are also some charging piles that may not be provided with a locking mechanism (such as home charging piles, etc.).

[0030] In a specific embodiment, the above-mentioned abnormality detection method can also be implemented by an abnormality detection device, wherein the abnormality detection device can include a second communication module, and the second communication module in the abnormality detection device can transmit signals with the first communication module in the target charging pile, thereby implementing the above-mentioned abnormality detection method. Specifically, the second communication module can transmit data through wireless signals.

[0031] Specifically, Figure 2 FIG. 1 is a flow chart of an abnormality detection method according to an exemplary embodiment. Figure 2 As shown, the anomaly detection method can be used in electronic devices such as terminals or servers, and can specifically include the following steps: S201: Obtain the current operation status of the target charging pile.

[0032] In a specific embodiment, the current pile operation state may include an unauthorized use state or an authorized use state. Among them, the unauthorized use state may refer to a state in which the user is not authorized to use the target charging pile; the authorized use state may refer to a state in which the user is authorized to use the target charging pile to achieve charging. It can be understood that when the target charging pile is in an unauthorized use state, and if the target charging pile includes a locking mechanism, the locking mechanism is in a locked state, and the gun line cannot be normally removed at this time; and for the target charging pile that does not include a locking mechanism, the target charging pile can remove the gun line from the charging pile or the vehicle charging port when it is in an unauthorized use state or an authorized use state; when the target charging pile is in an authorized use state, the locking mechanism is in an unlocked state, and the user can remove the gun line for charging.

[0033] In a specific embodiment, when the target charging pile is in an unauthorized use state, the step of obtaining current gun line status data corresponding to the target charging pile is executed. Accordingly, based on the current gun line status data, an abnormality detection can be performed on the gun line of the target charging pile to obtain a target gun line detection result. Therefore, when the target gun line detection result indicates that there is an abnormality in the gun line of the target charging pile, the video acquisition device corresponding to the target charging pile can be controlled to record the recorded gun line environment video corresponding to the target charging pile, and send an abnormal prompt signal to the target operation and maintenance terminal.

[0034] In the above embodiment, when the target charging pile is in an unauthorized use state, obtaining the current gun line state data corresponding to the target charging pile can avoid erroneous triggering of gun line abnormality detection due to normal use of the gun line by the user, thereby improving the accuracy of gun line abnormality detection.

[0035] S203: Obtain current gun line status data corresponding to the target charging pile.

[0036] In a specific embodiment, the current gun line state data can be used to indicate the current operating state of the gun line of the target charging pile. The gun line of the target charging pile can be used to achieve the connection between the target charging pile and the vehicle. The gun line of the target charging pile may include a charging gun of the target charging pile and a charging cable connected to the charging gun. Specifically, the current gun line state data may include current pressure data, current acceleration data, and current displacement data.

[0037] In a specific embodiment, the current pressure data may reflect the external force currently applied to the gun line of the target charging pile. The current pressure data may include charging gun pressure data or cable pressure data. The charging gun pressure data may refer to the pressure data between the charging gun of the target charging pile and the charging gun interface of the target charging pile. The cable pressure data may refer to the pressure data of the charging cable of the target charging pile. When the gun line is squeezed or pulled by an external force, the semiconductor strain gauge inside the pressure sensor will deform due to the external force, causing its resistance value to change, and the resistance change will be converted into a voltage signal output. It is understandable that when the gun line is pulled, squeezed or sheared, the pressure sensor near the force point (such as the pressure sensor near the force point in the cable or the pressure sensor in the charging gun) can detect abnormal changes in contact pressure. Secondly, the external force may cause structural deformation, which indirectly causes the pressure signal of the pressure sensor to change.

[0038] In a specific embodiment, the current acceleration data may reflect the movement of the gun line of the target charging pile. The current acceleration data may include charging gun acceleration data or cable acceleration data. The charging gun acceleration data may refer to the movement acceleration data of the charging gun of the target charging pile; the cable acceleration data may include multiple local acceleration data. Any local acceleration data may characterize the local movement acceleration of the cable at the current location of the corresponding acceleration sensor. When the gun line is impacted by an external force, the piezoelectric element inside the acceleration sensor is deformed due to inertia, the positive and negative charge centers are relatively displaced, a potential difference is generated, and a voltage signal proportional to the acceleration is output.

[0039] In a specific embodiment, the current displacement data can reflect the movement of the gun line of the target charging pile. The current displacement data may include charging gun displacement data or cable displacement data. The charging gun displacement data may be the relative displacement data between the charging gun of the target charging pile and the charging gun interface of the target charging pile. The cable displacement data may include multiple local displacement data. Any local displacement data can characterize the relative displacement between the current position of the corresponding displacement sensor and the position at the previous moment. Specifically, when the gun line is displaced, the sliding contact of the displacement sensor moves on the resistance rail, causing a change in the resistance value, thereby generating a voltage signal that is proportional to the displacement, thereby reflecting the displacement of the gun line.

[0040] In a specific embodiment, the above method may further include: When a signal transmission interruption signal sent by the target charging pile is received, the target gun line detection result is determined to be a first detection result.

[0041] In a specific embodiment, the signal transmission interruption signal can be used to indicate that the target charging pile detects that the temperature signal transmission of the charging gun temperature sensor of the target charging pile has stopped. Among them, the charging gun temperature sensor may refer to a temperature sensor built into the charging gun. The temperature sensor can be used to detect the current charging gun temperature of the target charging pile in real time, and transmit the detected temperature data to the controller of the target charging pile in real time. It should be noted that a temperature sensor can be configured in a common charging gun, and the above-mentioned charging gun temperature sensor utilizes the existing temperature sensor in the charging gun, and there is no need to increase hardware costs.

[0042] Specifically, the charging gun temperature sensor can send a signal containing the current charging gun temperature to the controller of the target charging pile at intervals of a first preset time. Optionally, the first preset time can be 10ms. Accordingly, the controller of the target charging pile can receive a signal of the current charging gun temperature sent by the charging gun temperature sensor at intervals of the first preset time.

[0043] In a specific embodiment, the controller of the target charging pile may generate a signal transmission interruption signal when detecting that the signal transmission of the charging gun temperature sensor stops. Specifically, the controller of the target charging pile may determine that the signal transmission of the charging gun temperature sensor stops when detecting that the signal of the current charging gun temperature of the charging gun temperature sensor is not received for more than a second preset time, and accordingly, may generate a signal transmission interruption signal. The second preset time may be greater than the first preset time. Optionally, the second preset time may be 2s.

[0044] In a specific embodiment, the target gun line detection result can be used to indicate whether the gun line of the target charging pile is in an abnormal state. The target gun line detection result may include a first detection result or a second detection result. The first detection result can be used to indicate that the gun line of the target charging pile is in an abnormal state. The second detection result can be used to indicate that the gun line of the target charging pile is in a normal state. It can be understood that when the target gun line detection result is the first detection result, it can be determined that the gun line of the target charging pile may be in a state of being maliciously damaged.

[0045] In a specific embodiment, when a signal transmission interruption signal is received from a target charging pile, it may be that the sensor data communication transmission of the charging gun temperature sensor is interrupted due to the gun line being cut and the charging gun temperature sensor is in an abnormal state, and the target gun line detection result can be determined to be the first detection result. Correspondingly, when it is determined that the target gun line detection result is the first detection result, that is, the target gun line detection result indicates that there is an abnormality in the gun line of the target charging pile, the video acquisition device corresponding to the target charging pile can be controlled to record the recorded gun line environment video corresponding to the target charging pile, and send an abnormal prompt signal to the target operation and maintenance terminal. That is, an alarm prompt signal can be sent to the target operation and maintenance terminal to prompt the operation and maintenance personnel to check the actual specific situation of the target charging pile.

[0046] In the above embodiment, by determining the target gun line detection result as the first detection result when receiving the signal transmission interruption signal sent by the target charging pile, the gun line abnormality detection of the target charging pile can be achieved without increasing the hardware cost, thereby improving the accuracy of the gun line abnormality, improving the safety of the charging pile gun line, and then improving the user experience and enhancing the practicality of the system.

[0047] S205: Based on the current gun line status data, an abnormality detection is performed on the gun line of the target charging pile to obtain a target gun line detection result.

[0048] In a specific embodiment, the target gun line detection result can be used to indicate whether the gun line of the target charging pile is in an abnormal state. The target gun line detection result may include a first detection result or a second detection result. The first detection result may be used to indicate that the gun line of the target charging pile is in an abnormal state. The second detection result may be used to indicate that the gun line of the target charging pile is in a normal state.

[0049] In a specific embodiment, the above-mentioned abnormal detection of the gun line of the target charging pile based on the current gun line state data to obtain the target gun line detection result may include: Matching the current pressure data with the preset pressure threshold data to obtain a pressure matching result; Matching the current acceleration data with the preset acceleration threshold data to obtain an acceleration matching result; Performing matching processing on the current displacement data and the preset displacement threshold data to obtain a displacement matching result; The target gun line detection result is determined based on the pressure matching result, the acceleration matching result and the displacement matching result.

[0050] In a specific embodiment, the pressure matching result can be used to indicate whether the current pressure data matches the preset pressure threshold data. The preset pressure threshold data can refer to the pressure threshold data at which the gun line may be subjected to abnormal external force. Specifically, the preset pressure threshold data can be set according to actual application needs. The pressure matching result may include a first matching result or a second matching result. The first matching result can be used to indicate that there is at least one pressure data in the current pressure data that exceeds the preset pressure threshold data. The second matching result can be used to indicate that multiple pressure data in the current pressure data do not exceed the preset pressure threshold data.

[0051] In a specific embodiment, the acceleration matching result can be used to indicate whether the current acceleration data and the preset acceleration threshold data match. The preset acceleration threshold data can be used to determine whether the gun line of the target charging pile is impacted by external force damage. Specifically, the preset acceleration threshold data can be set according to actual application needs. The acceleration matching result may include a third matching result or a fourth matching result. The third matching result can be used to indicate that there is at least one acceleration data in the current acceleration data that exceeds the preset acceleration threshold data. The fourth matching result can be used to indicate that multiple acceleration data in the current acceleration data do not exceed the preset acceleration threshold data.

[0052] In a specific embodiment, the displacement matching result can be used to indicate whether the current displacement data matches the preset displacement threshold data. The preset displacement threshold data can be used to determine whether the gun line of the target charging pile has abnormal movement such as displacement changes too fast or exceeds a certain range. Specifically, the preset displacement threshold data can be set according to actual application needs. The displacement matching result may include a fifth matching result or a sixth matching result. The fifth matching result can be used to indicate that there is at least one displacement data in the current displacement data that exceeds the preset displacement threshold data. The sixth matching result can be used to indicate that multiple displacement data in the current displacement data do not exceed the preset displacement threshold data.

[0053] In a specific embodiment, determining the target gun line detection result based on the pressure matching result, the acceleration matching result and the displacement matching result may include: When the pressure matching result, the acceleration matching result or the displacement matching result belongs to the target matching result, determining the target gun line detection result as the first detection result; or, When the pressure matching result, the acceleration matching result, and the displacement matching result do not belong to the target matching result, the target gun line detection result is determined to be the second detection result.

[0054] In a specific embodiment, the target matching result may be used to indicate that the corresponding state data contains data exceeding the corresponding threshold.

[0055] In a specific embodiment, when the pressure matching result is the first matching result, it can be determined that the pressure matching result belongs to the target matching result; when the acceleration matching result is the third matching result, it can be determined that the acceleration matching result belongs to the target matching result; when the displacement matching result is the fifth matching result, it can be determined that the displacement matching result belongs to the target matching result.

[0056] In a specific embodiment, when the pressure matching result, acceleration matching result or displacement matching result belongs to the target matching result, it can be determined that at least one state data in the target gun line state data of the gun line of the target charging pile exceeds the threshold, and the target gun line detection result can be determined as the first detection result. It can be understood that when the matching result corresponding to any one of the pressure data, acceleration data and displacement data indicates that the current gun line may be abnormal, the target gun line detection result can be determined as the first detection result.

[0057] In a specific embodiment, when the target charging pile includes a locking mechanism, the current gun line status data may include current pressure data (which may include cable pressure data or charging gun pressure data), cable acceleration data and cable displacement data, and abnormal detection of the gun line can be achieved through the above current gun line status data.

[0058] In a specific embodiment, for a charging pile that includes a locking mechanism, the acquired charging gun acceleration data and charging gun displacement data may both be empty, or may both be 0; or there may also be acts of destruction or theft such as violently destroying the locking mechanism, or bypassing the electronic lock system (such as blocking the communication between the charging pile and the gun head lock through an electromagnetic jammer, making the locking state invalid, etc.), and further stealing the charging pile gun line. At this time, since the locking mechanism can no longer be locked normally, the charging gun displacement data and the charging gun acceleration data can be collected through the sensor in the charging gun during the movement of the charging gun.

[0059] In the above embodiment, the pressure matching result is obtained by matching the current pressure data with the preset pressure threshold data, the acceleration matching result is obtained by matching the current acceleration data with the preset acceleration threshold data, and the displacement matching result is obtained by matching the current displacement data with the preset displacement threshold data. Based on the pressure matching result, the acceleration matching result and the displacement matching result, the target gun line detection result is determined, which can improve the abnormal detection accuracy of the gun line of the target charging pile, thereby improving the safety of the charging pile gun line, improving the user experience, and enhancing the practicality of the system.

[0060] S207: When the target gun line detection result indicates that there is an abnormality in the gun line of the target charging pile, control the video acquisition device corresponding to the target charging pile to record the recorded gun line environment video corresponding to the target charging pile, and send an abnormal prompt signal to the target operation and maintenance terminal.

[0061] In a specific embodiment, the recorded gun line environment video may be a video of the gun line of the target charging pile and its surrounding environment recorded when an abnormality is detected in the gun line. It is understandable that the retention of video data provides strong evidence for subsequent accountability, further enhancing the practicality of the system.

[0062] In a specific embodiment, when the target gun line detection result indicates that there is an abnormality in the gun line of the target charging pile, a recording start signal can be sent to the video acquisition device to control the video acquisition device to start recording the target charging pile and the surrounding environment video to obtain a recorded gun line environment video.

[0063] In a specific embodiment, when the target gun line detection result indicates that there is an abnormality in the gun line of the target charging pile, the alarm module can be controlled to issue an alarm.

[0064] In a specific embodiment, the target operation and maintenance terminal may be a terminal used for operation and maintenance personnel.
