[0045] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the drawings denote elements having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0046] The term "exemplary" used herein means "serving as an example, embodiment, or illustration". Any embodiment described herein as "exemplary" does not have to be construed as superior to or better than other embodiments.

[0047] In addition, for a better description of the present application, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0048] Please refer to Figure 1 , Figure 1 which is a block diagram of a target charging pile shown according to an exemplary embodiment. Specifically, as Figure 1 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 anomaly detection method. The first communication module can be used to receive or send data, such as an anomaly prompt signal, a real-time gun line environment video, or a recorded gun line environment video, etc.; specifically, the first communication module can transmit data through a wireless signal. The alarm module may include an audible and visual alarm. The video acquisition device can be used to collect video data of the gun line of the target charging pile and its surrounding environment. The video acquisition device can adopt a 1080P resolution, support night vision and wide-angle shooting, and is installed on the top of the target charging pile to cover the gun line and the surrounding area; the storage device of the video acquisition device selects a 64GB SD card and supports loop recording. Further, a sensor module may be provided on the gun line corresponding to the target charging pile; the sensor module can be used to collect and transmit the current gun line state data of the charging pile gun line. The sensor module may be disposed inside the gun line of the target charging pile. The sensor module may include a built-in communication unit; the above-mentioned built-in communication unit can be used to transmit the collected current gun line state data to the first communication module of the target charging pile, so that the above-mentioned current gun line state data can be transmitted to the controller of the target charging pile through the first communication module. Specifically, communication between the communication unit and the first communication module can be achieved through a wired signal or a wireless signal. Optionally, when the wired communication between the communication unit and the first communication module is disconnected, communication between the two can be achieved through a wireless signal.

[0049] In a specific embodiment, the sensor module may include a first sensor sub-module and a plurality of second sensor sub-modules. The first sensor sub-module may be disposed on the charging gun corresponding to the target charging pile; the plurality of second sensor sub-modules may be respectively disposed at different positions of the charging cable corresponding to the target charging pile. Among them, the first sensor sub-module may include a pressure sensor, a displacement sensor, and an acceleration sensor; any one of the second sensor sub-modules may include one or more of a pressure sensor, a displacement sensor, and an acceleration sensor. Exemplarily, the number of the second sensor sub-modules may be at least three, two of the second sensor sub-modules may be disposed at both ends of the charging cable, and the remaining second sensor sub-modules may be disposed in the middle of the charging cable, and the cross-sectional positions of the cables where the setting positions of each second sensor sub-module are located are all different. Further, each sensor may be built-in with a communication unit; each sensor may send data through the communication unit.

[0050] In the above embodiment, by setting the above sensor module on the gun line, and the multiple sensor sub-modules in the sensor module can be set at different positions in the gun line, it is possible to collect the pressure data, acceleration data, and displacement data at different positions of the gun line, thereby improving the accuracy of abnormal recognition of the gun line of the target charging pile.

[0051] In a specific embodiment, the target charging pile may include a charging gun backup power supply, and the above backup power supply may be disposed in the charging gun of the target charging pile. The above charging gun backup power supply may be used to supply power to the sensor module when the power supply from the target charging pile to the charging gun is disconnected. 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 (i.e., no abnormality such as the cable being cut occurs), the sensor module in the charging gun can be powered by the charging pile, 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 normally powered (such as an abnormality such as the cable being cut occurs), that is, at this time the charging pile cannot supply power to the sensor module, the charging gun backup power supply can supply power (it can be detected that the power supply of the charging gun is disconnected, and the switch between the charging gun backup power supply and the sensor module is controlled to close, so that the charging gun backup power supply supplies power to the sensor module).

[0052] In a specific embodiment, the charging gun backup power supply and the sensor module may be connected through a normally closed relay; the charging pile may output a control signal through the charging cable and connect it to the coil of the relay; when the charging cable of the charging pile is normally powered, the coil of the relay is energized and the relay is disconnected; when the charging cable of the charging pile is disconnected and cannot be normally powered, the coil of the relay is not energized and the relay is closed, and the charging gun backup power supply can supply power to the sensor module.

[0053] In a specific embodiment, when the disconnection position of the charging cable is between any two sensor sub-modules, the backup power supply of the charging gun can supply power to at least one sensor sub-module in the charging cable segment of the part connected to the charging gun; when there is at least one sensor sub-module in the charging cable segment of the part connected to the target charging pile, the target charging pile can supply power to at least one sensor sub-module existing in the charging cable segment of the part connected to the target charging pile.

[0054] In the above embodiment, by setting a backup power supply in the charging gun, the power supply of the sensors in the cable segment connected to the charging gun after the charging cable is cut can be realized, the acquisition of pressure data, acceleration data and displacement data for the cable segment connected to the charging gun can be realized, and thus the accuracy of abnormal recognition of the gun line of the target charging gun can be improved.

[0055] In a specific embodiment, as Figure 1 shown, the target charging pile may further include a locking mechanism. The locking mechanism can be used to prevent the user from pulling out the gun line of the target charging pile without authorization; the locking mechanism can include an electromagnetic lock or a mechanical lock. It can be understood that there are some charging piles that can be equipped with a locking mechanism (such as public charging piles, etc.), and there are also some charging piles that are not equipped with a locking mechanism (such as home charging piles, etc.).

[0056] In a specific embodiment, the above abnormal detection method can also be implemented by an abnormal detection device. Among them, the abnormal detection device can include a second communication module, and signal transmission can be realized through the second communication module in the abnormal detection device and the first communication module in the target charging pile, thereby implementing the above abnormal detection method. Specifically, the second communication module can transmit data through wireless signals.

[0057] Specifically, Figure 2 is a flowchart of an abnormal detection method shown according to an exemplary embodiment. As Figure 2 shown, this abnormal detection method can be used in electronic devices such as terminals or servers, and specifically may include the following steps:

[0058] S201: Obtain the current operating state of the target charging pile.

[0059] In a specific embodiment, the current operating state of the current pile may include an unauthorized use state or an authorized use state. Among them, the unauthorized use state may refer to the state where the user is not authorized to use the target charging pile; the authorized use state may refer to the state where 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 the unauthorized use state and if the target charging pile includes a locking mechanism, the locking mechanism is in the locked state, and at this time, the gun line cannot be taken out normally; for the target charging pile without a locking mechanism, the gun line can be taken out from the charging pile or the vehicle charging port when the target charging pile is in the unauthorized use state or the authorized use state; when the target charging pile is in the authorized use state, the locking mechanism is in the unlocked state, and at this time, the user can take out the gun line to charge.

[0060] In a specific embodiment, when the target charging pile is in the unauthorized use state, the step of obtaining the current gun line state data corresponding to the target charging pile is executed. Correspondingly, based on the current gun line state data, the gun line of the target charging pile can be abnormally detected to obtain the target gun line detection result. Thus, when the target gun line detection result indicates that the gun line of the target charging pile is abnormal, 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 an abnormal prompt signal can be sent to the target operation and maintenance terminal.

[0061] In the above embodiment, when the target charging pile is in the unauthorized use state, obtaining the current gun line state data corresponding to the target charging pile can avoid false triggering of the abnormal detection of the gun line due to the normal use of the gun line by the user, and thus can improve the accuracy of the abnormal detection of the gun line.

[0062] S203: Obtain the current gun line state data corresponding to the target charging pile.

[0063] 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. Among them, the gun line of the target charging pile can be used to realize the connection between the target charging pile and the vehicle. The gun line of the target charging pile can include the charging gun of the target charging pile and the charging cable connected to the above charging gun. Specifically, the current gun line state data can include the current pressure data, the current acceleration data, and the current displacement data.

[0064] In a specific embodiment, the current pressure data can reflect the external force currently exerted on the gun line of the target charging pile. The current pressure data can include charging gun pressure data or cable pressure data. The charging gun pressure data can 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 can refer to the pressure data of the charging cable of the target charging pile. When the gun line is subjected to external force extrusion or pulling, the semiconductor strain gauge inside the pressure sensor will deform due to the external force, resulting in a change in its resistance value, and the resistance change will be converted into a voltage signal output. It can be understood that when the gun line is pulled, squeezed or sheared, the pressure sensors near the stress point (such as the pressure sensors near the stress point inside the cable or the pressure sensors inside the charging gun) can detect abnormal changes in the contact pressure. Secondly, the external force may cause structural deformation, indirectly causing changes in the pressure signal of the pressure sensor.

[0065] In a specific embodiment, the current acceleration data can reflect the movement of the gun line of the target charging pile. The current acceleration data can include charging gun acceleration data or cable acceleration data. The charging gun acceleration data can refer to the moving acceleration data of the charging gun of the target charging pile; the cable acceleration data can include multiple local acceleration data. Any local acceleration data can characterize the moving acceleration of the local part of the cable where the corresponding acceleration sensor is currently located. When the gun line is subjected to an external force impact, the piezoelectric element inside the acceleration sensor deforms due to inertia, the positive and negative charge centers undergo relative displacement, generating a potential difference, and outputting a voltage signal proportional to the acceleration.

[0066] 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 can include charging gun displacement data or cable displacement data. The charging gun displacement data can 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 can include multiple local displacement data. Any local displacement data can characterize the relative displacement between the current position of the corresponding displacement sensor and its position at the previous moment. Specifically, when the gun line undergoes displacement, the sliding contact of the displacement sensor moves on the resistance rail, causing a change in the resistance value, thereby generating a voltage signal proportional to the displacement, and further reflecting the displacement of the gun line.

[0067] In a specific embodiment, the above method may further include:

[0068] When receiving a signal transmission interruption signal sent by the target charging pile, determining that the target gun line detection result is the first detection result.

[0069] 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 temperature sensor of the charging gun of the target charging pile has stopped. Among them, the charging gun temperature sensor can refer to the temperature sensor built into the charging gun. The temperature sensor can be used to detect the current temperature of the charging gun 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. The above-mentioned charging gun temperature sensor utilizes the existing temperature sensor in the charging gun, and there is no need to increase the hardware cost.

[0070] Specifically, the charging gun temperature sensor can send a signal containing the current charging gun temperature to the controller of the target charging pile every first preset time interval. Optionally, the above-mentioned first preset time interval can be 10 ms. Correspondingly, the controller of the target charging pile can receive the signal of the current charging gun temperature sent by the above-mentioned charging gun temperature sensor every first preset time interval.

[0071] In a specific embodiment, when the controller of the target charging pile detects that the signal transmission of the charging gun temperature sensor has stopped, it can generate a signal transmission interruption signal. Specifically, when the controller of the target charging pile detects that it has not received the signal of the current charging gun temperature of the charging gun temperature sensor for more than a second preset time interval, it can determine that the signal transmission of the charging gun temperature sensor has stopped. Correspondingly, it can generate a signal transmission interruption signal. Among them, the second preset time interval can be greater than the first preset time interval. Optionally, the second preset time interval can be 2 s.

[0072] 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 can 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 maliciously damaged state.

[0073] In a specific embodiment, when a signal transmission interruption signal sent by a target charging pile is received, it may be due to the gun line being cut, resulting in the interruption of the sensor data communication transmission of the charging gun temperature sensor and being in an abnormal state. It can be determined that the target gun line detection result is 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 video of the gun line environment corresponding to the target charging pile, and an abnormal prompt signal can be sent 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.

[0074] In the above embodiment, by determining that the target gun line detection result is the first detection result when a signal transmission interruption signal sent by the target charging pile is received, the abnormal detection of the gun line of the target charging pile can be realized without increasing the hardware cost, thereby improving the accuracy of gun line abnormality, improving the safety of the charging pile gun line, further improving the user experience, and enhancing the practicality of the system.

[0075] S205: Based on the current gun line status data, perform abnormal detection on the gun line of the target charging pile to obtain the target gun line detection result.

[0076] 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 can 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.

[0077] In a specific embodiment, the above-mentioned performing abnormal detection on the gun line of the target charging pile based on the current gun line status data to obtain the target gun line detection result may include:

[0078] Perform a matching process on the current pressure data and the preset pressure threshold data to obtain a pressure matching result;

[0079] Perform a matching process on the current acceleration data and the preset acceleration threshold data to obtain an acceleration matching result;

[0080] Perform a matching process on the current displacement data and the preset displacement threshold data to obtain a displacement matching result;

[0081] Based on the pressure matching result, the acceleration matching result, and the displacement matching result, determine the target gun line detection result.

[0082] 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 when the gun line may be subjected to abnormal external forces. Specifically, the preset pressure threshold data can be set according to actual application requirements. The pressure matching result can include a first matching result or a second matching result. The first matching result can be used to indicate that at least one pressure data in the current pressure data 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.

[0083] In a specific embodiment, the acceleration matching result can be used to indicate whether the current acceleration data matches the preset acceleration threshold data. The preset acceleration threshold data can be used to determine whether there is an impact caused by external force damage to the gun line of the target charging pile. Specifically, the preset acceleration threshold data can be set according to actual application requirements. The acceleration matching result can include a third matching result or a fourth matching result. The third matching result can be used to indicate that at least one acceleration data in the current acceleration data 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.

[0084] 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 there are abnormal movement conditions such as too fast displacement change or exceeding a certain range of the gun line of the target charging pile. Specifically, the preset displacement threshold data can be set according to actual application requirements. The displacement matching result can include a fifth matching result or a sixth matching result. The fifth matching result can be used to indicate that at least one displacement data in the current displacement data 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.

[0085] 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:

[0086] 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;

[0087] Or,

[0088] When the pressure matching result, the acceleration matching result, and the displacement matching result do not belong to the target matching result, determining the target gun line detection result as the second detection result.

[0089] In a specific embodiment, the target matching result can be used to indicate that there is data in the corresponding status data that exceeds the threshold corresponding thereto.

[0090] 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.

[0091] In a specific embodiment, when the pressure matching result, the acceleration matching result, or the displacement matching result belongs to the target matching result, it can be determined that there is at least one status data in the target cable state data of the target charging pile that exceeds the threshold, and it can be determined that the target cable detection result is the first detection result. It can be understood that when the matching result corresponding to any one of the pressure data, the acceleration data, and the displacement data indicates that the current cable may be abnormal, the target cable detection result can be determined to be the first detection result.

[0092] In a specific embodiment, when the target charging pile includes a locking mechanism, the current cable state 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 the abnormal detection of the cable can be realized through the above current cable state data.

[0093] In a specific embodiment, for a charging pile including a locking mechanism, the obtained 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 theft or damage such as violently damaging 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 to invalidate the locked state), etc., and then further realizing the theft of the charging pile cable.
