Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of charging piles, and in particular to a method and device for maintaining a charging pile gun, a charging pile, and a medium. Background Art

[0002] Traditional charging pile gun return detection relies on threshold detection. Specifically, it determines the gun insertion status by judging the detection threshold of the detection sensor set on the gun holder of the charging pile. For example, ultrasonic gun return detection uses the infrared signal sensor on the gun holder to detect the intensity of the ultrasonic signal reflected by the gun head to complete the return detection. When the intensity is greater than the preset value, it is considered that the charging gun is plugged back into the socket; when it is less than the preset threshold, it is considered that the charging gun is not plugged into the socket.

[0003] During the process of implementing the embodiments of the present application, the inventors of the present application discovered that when using threshold detection to return the gun, due to aging of the detection module components of the charging gun and the charging pile, or differences in the installation environment, etc., there may be a large difference between the actual detection value and the standard value, resulting in an abnormal judgment. The user may have returned the gun, but it has not been detected, which greatly affects the user experience and increases after-sales costs. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a charging pile gun return maintenance method, device, charging pile and medium, which can autonomously detect whether a gun return abnormality occurs and the authenticity of the abnormality at the end of charging.

[0017] Subtracting the minimum value of gun drawing from the first difference to obtain a third difference;

[0018] If the second difference is smaller than the second preset constant value, and the third difference is smaller than or equal to the sum of the first preset constant value and the second preset constant value, the return gun threshold is maintained, and it is determined that the distance sensor on the gun mount is damaged.

[0019] In some embodiments, after obtaining the third difference, the method further includes:

[0025] In some embodiments, after obtaining the first return fire signal value of the gun holder, the method further includes:

[0026] If the first gun return signal value is greater than the gun return threshold, the gun return threshold and the gun withdrawal threshold are maintained.

The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0047] In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0048] The charging pile gun maintenance method and device provided in the embodiment of the present application can be applied to charging piles, such as Figure 1 As shown, the charging pile 10 includes a controller 11 and a gun holder 100, and the charging pile 10 is connected to the charging gun 20; the gun holder 100 provided on the charging pile 10 allows the charging gun 20 to be inserted into the gun holder 100, so that the user can return the gun; a distance sensor is provided on the gun holder 100, and an ultrasonic or infrared signal transmitting module is provided on the gun head of the charging gun 20. The distance sensor and the ultrasonic or infrared signal transmitting module constitute a gun return detection module. The distance sensor on the gun holder 100 can detect the signal strength at the gun head. When the gun head of the charging gun 20 is closer to the gun holder, the signal strength detected by the distance sensor is greater. When the signal strength value detected by the distance sensor is greater than the gun return threshold, it is considered that the gun is returned successfully; when the gun head of the charging gun 20 is farther away from the gun holder, the signal strength detected by the distance sensor is smaller. When the signal strength value detected by the distance sensor is less than the gun withdrawal threshold, it is considered that the gun is withdrawn successfully, and when the charging gun is connected to the charging port of the electric vehicle after withdrawing the gun, so that the charging pile is in a charging state, the signal strength value detected by the distance sensor is the smallest.

[0049] See Figure 2, is a flow chart of an embodiment of a gun return maintenance method for a charging pile applied to the present application. The method can be executed by the controller 11 in the charging pile, and the method includes steps S201 to S203.

[0050] S201: When the charging pile is in a charging end state, obtaining a first return-fire signal value of the gun holder.

[0051] When users need to use a charging gun to charge their electric vehicles, Figure 3 As shown, the user's smart terminal 30 is in communication with the charging pile 10. The smart terminal 30 is equipped with an application program related to controlling the charging pile 10. The user can send some control instructions to the charging pile 10 through the application program on the smart terminal 30, such as a start charging instruction and / or a stop charging instruction. When the charging pile 10 receives the start charging instruction sent by the smart terminal 30, if the charging gun 20 is connected to the charging port of the electric vehicle, it will start charging the electric vehicle; when charging is completed, or when the user sends a stop charging instruction to the charging pile 10 through the smart terminal 30, the charging order is completed and the charging is in the end state. Therefore, the end state detected by the charging pile 10 may be the case where the user has completed the order to charge the electric vehicle using the charging gun.

[0052] When the charging station is in the charging end state, the controller 11 of the charging station 10 obtains the first return signal value of the gun holder 100 after a period of time (e.g., half a minute) after charging is completed. Since the user may not insert the charging gun 20 into the gun holder 100 in time after charging, the charging station 10 sets this period of time to give the user an opportunity to return the gun in time, thereby avoiding inaccurate detection caused by immediately detecting the return signal value after the order is completed.

[0053] Then, the controller 11 of the charging pile 10 judges the first gun return signal value. If the first gun return signal value is less than the gun return threshold Tr1, the charging pile 10 determines that the charging gun is in a non-returned state. At this time, the charging pile 10 sends a prompt message to the smart terminal 30, and the prompt message is used to remind the user that the gun has not been returned; the smart terminal 30 is used to return feedback information that the gun has been returned.

[0054] Correspondingly, if the first gun return signal value is not less than the gun return threshold Tr1, it means that the charging gun 20 is in the gun return state and the gun return detection module of the charging pile 10 is operating normally, and there is no need to adjust the threshold. At this time, the gun return threshold and the gun removal threshold are maintained.

[0055] S202: If the gun return feedback information is received and the first gun return signal value is updated to a second gun return signal value, determine whether the second gun return signal value is less than a gun return threshold.

[0056] Specifically, when the charging station sends a prompt message to the smart terminal, the user sees the prompt and takes the corresponding action; otherwise, the order remains incomplete. If the user confirms that they have returned the gun, they can click the "Returned" button in the smart terminal app. The charging station then receives the return notification. If the position of the charging gun has not changed, the first return signal value detected by the gun holder remains. If the position of the charging gun has changed, the first return signal value detected by the gun holder is updated to the second return signal value. Alternatively, if the user realizes that they have not returned the gun, they can click the "Returned" button in the smart terminal app and insert the charging gun into the gun holder. At this time, the first return signal value is updated to the second return signal value, and the charging station also receives the return notification.

[0057] After the first return signal value is updated to the second return signal value, the charging station determines whether the second return signal value is less than the return threshold. By determining whether the second return signal value is less than the return threshold, it can be determined whether the return detection module on the charging station's gun holder is functioning properly. If the return detection module is faulty, even if the user has returned the gun, it will still display "not returned" as the gun has not been returned, resulting in a poor user experience. Therefore, the return module failure needs to be corrected.

[0058] S203: If the second gun return signal value is not less than the gun return threshold, it is determined that the gun return is normal.

[0059] Specifically, if the second gun return signal value is not less than the gun return threshold, it means that the gun return detection module is working normally. At this time, the charging pile determines that the gun return is normal and can send a prompt message of "gun return successful" to the smart terminal.

[0060] It can be understood that the charging pile can set a preset time length for judging whether the second gun return signal value is not less than the gun return threshold value, and the preset time length can be two minutes. Within two minutes, it is judged whether the second gun return signal value V2 is greater than or equal to the gun return threshold value Tr1, or the second gun return signal value V2 changes to be greater than or equal to the gun return threshold value Tr1, then it means that the gun return detection module is normal. Before the first gun return signal value is updated to the second gun return signal value, the user forgot to return the gun. At this time, no threshold update processing is required.

[0061] S204: If the second gun return signal value is less than the gun return threshold, it is determined that the gun return is abnormal, and the gun return threshold and / or gun withdrawal threshold are re-determined.

[0062] Specifically, if the second gun return signal value is less than the gun return threshold, it indicates that the gun return detection module is abnormal. At this time, the charging pile determines that the gun return is abnormal and redefines the gun return threshold and / or gun removal threshold.

[0063] It should be noted that the charging station can be set to a preset duration of two minutes to determine whether the second return signal value V2 is less than the return threshold Tr1, or is continuously less than the return threshold Tr1 within two minutes. If the second return signal value V2 is less than the return threshold Tr1, or is continuously less than the return threshold Tr1, it indicates that the return is abnormal, triggering a threshold update. The threshold includes the return threshold and / or the withdrawal threshold.

[0064] In some embodiments, re-determining the return threshold may include:

[0065] subtracting a first preset constant value from the second return gun signal value to obtain a first difference;

[0066] subtracting the gun-drawing threshold from the first difference to obtain a second difference;

[0067] If the second difference is greater than or equal to a second preset constant value, the return threshold is updated to the first difference.

[0068] Specifically, when the charging pile determines that an abnormality occurs in the gun return detection module, the first preset constant value is subtracted from the second gun return signal value to obtain a first difference. The second gun return signal value is represented by V1, the first preset constant value is represented by Tr_CONST, and the first difference is represented by Tr1'. Therefore, Tr1'=V1-Tr_CONST.

[0069] Then, the gun-drawing threshold is subtracted from the first difference to obtain a second difference; wherein the gun-drawing threshold is represented by Tr2, so the second difference = Tr1'-Tr2.

[0070] Determine the relationship between the second difference and the second preset constant value, the second preset constant value is represented by Tr_Delta_Min, and the gun return threshold is represented by Tr1. If the second difference is greater than or equal to the second preset constant value, that is, Tr1'-Tr2≥Tr_Delta_Min, it means that the gun return threshold is abnormal, but the distance sensor in the gun return detection module is not damaged, but the current gun return threshold Tr1 is too small and needs to be increased to achieve normal gun return detection. Therefore, the gun return threshold is updated to the first difference, that is, Tr1=Tr1'.

[0071] It can be understood that due to hardware differences and considering issues such as device aging during subsequent use, the signal strength value detected when the charging gun is unplugged before the charging pile and the charging gun leave the factory cannot be directly used as a threshold. Usually, an offset is added to this signal strength value as the threshold. Therefore, this offset is the first preset constant value Tr_CONST; the second preset constant value Tr_Delta_Min is the minimum difference that needs to be maintained between the two thresholds of the gun-returning threshold Tr1 and the unplugging threshold Tr2.

[0072] In some of these embodiments, after obtaining the second difference by subtracting the unplugging threshold from the first difference, the method further includes:

[0073] Obtain the minimum unplugging value, which is the signal strength value of the charging gun detected by the gun base when the charging pile is in the charging state;

[0074] Subtract the minimum unplugging value from the first difference to obtain a third difference;

[0075] If the second difference is less than the second preset constant value and the third difference is less than or equal to the sum of the first preset constant value and the second preset constant value, then maintain the gun-returning threshold and determine that the distance sensor on the gun base is damaged.

[0076] Specifically, after obtaining the second difference, in order to further determine whether the distance sensor on the gun base is damaged, first obtain the minimum unplugging value V2_Min. The minimum unplugging value is the signal strength value of the charging gun detected by the gun base when the charging pile is in the charging state, that is, when the charging gun is inserted into the electric vehicle for charging, the signal strength value detected by the gun base is the minimum unplugging value. Then, subtract the minimum unplugging value from the first difference to obtain a third difference, that is, the third difference = Tr1‘ - V2_Min; if the second difference is less than the second preset constant value and the third difference is less than or equal to the sum of the first preset constant value and the second preset constant value, that is, if the second difference Tr1' - Tr2 < Tr_Delta_Min and Tr1‘ - V2_Min ≤ Tr_Delta_Min + Tr_CONST, it means that the gun-returning detection module is damaged, resulting in inaccurate detection. At this time, there is no need to re-determine the gun-returning threshold and / or the unplugging threshold Tr1, maintain the gun-returning threshold Tr1, and the charging pile determines that the distance sensor on the gun base is damaged.

[0077] In some of these embodiments, the charging pile is communicatively connected to the intelligent terminal; after determining that the distance sensor on the gun base is damaged, the method further includes:

[0078] Send the information that the distance sensor is damaged to the intelligent terminal.

[0079] After the charging pile determines that the distance sensor is damaged, the charging pile sends the information that the distance sensor is damaged to the intelligent terminal. The intelligent terminal displays that the gun-returning module fails, so that the user gets the information that the gun-returning module fails. Moreover, the intelligent terminal can continuously display that the gun-returning module fails to remind the user.

[0080] Moreover, after the charging pile determines that the distance sensor on the gun seat is damaged, the judgment of the gun-returning logic is terminated.

[0081] In some embodiments, after obtaining the third difference, the method further includes:

[0082] If the second difference is less than the second preset constant value, and the third difference is greater than the sum of the first preset constant value and the second preset constant value, update the gun-returning threshold to the first difference, and update the gun-drawing threshold to the sum of the minimum gun-drawing value and the first preset constant value.

[0083] Specifically, after obtaining the third difference, if the second difference Tr1'-Tr2 is less than the second preset constant value Tr_Delta_Min, that is, Tr1'-Tr2 < Tr_Delta_Min, and the third difference is greater than the sum of the first preset constant value and the second preset constant value, that is, Tr1‘-V2_Min > Tr_Delta_Min+Tr_CONST, it means that the gun-returning detection module is not damaged, but the threshold is not sufficient to meet the judgment of gun-returning or gun-drawing. Therefore, both the gun-returning threshold and the gun-drawing threshold need to be updated. At this time, update the gun-returning threshold to the first difference, that is, Tr1 = Tr1’; and update the gun-drawing threshold to the sum of the minimum gun-drawing value and the first preset constant value, that is, Tr2 = V2_Min+Tr_CONST.

[0084] In the embodiments of the present application, obtain the first gun-returning signal value of the gun seat, that is, detect whether the charging gun is in the state of being returned at this time; if the returned gun feedback information is received and the first gun-returning signal value is updated to the second gun-returning signal value, it means that the user may have inserted the charging gun back into the gun seat, resulting in a change in the gun-returning signal value. At this time, judge whether the updated second gun-returning signal value is less than the gun-returning threshold to judge the authenticity of the possible abnormality and avoid continuous misjudgment; if the second gun-returning signal value is not less than the gun-returning threshold, it is determined that the gun-returning is normal. At this time, it means that the gun-returning detection module on the gun seat is in a normal working state; if the second gun-returning signal value is less than the gun-returning threshold, it is determined that the gun-returning is abnormal, and the gun-returning detection module may be in a fault state, and re-determine the gun-returning threshold and / or the gun-drawing threshold to restore the normal control of gun-returning, so as to improve the accuracy of gun-returning detection.

[0085] The embodiments of the present application also provide a gun-returning maintenance device for a charging pile.

[0089] The second confirmation module 404 is configured to determine that the gun return is abnormal if the second gun return signal value is less than the gun return threshold, and redetermine the gun return threshold and / or gun withdrawal threshold.

[0090] In an embodiment of the present application, a first gun return signal value is obtained from the gun holder, that is, whether the charging gun is in a returned state at this time; if feedback information of the returned gun is received, and the first gun return signal value is updated to a second gun return signal value, it means that the user may have inserted the charging gun back into the gun holder, resulting in a change in the gun return signal value. At this time, it is determined whether the second gun return signal value obtained after the update is less than the gun return threshold value to determine the authenticity of the possible abnormality and avoid continuous misjudgment; if the second gun return signal value is not less than the gun return threshold value, it is determined that the gun return is normal, and the gun return detection module on the gun holder is in normal working condition; if the second gun return signal value is less than the gun return threshold value, it is determined that the gun return is abnormal, and the gun return detection module may be in a fault state, and the gun return threshold and / or gun withdrawal threshold are re-determined to restore normal control of the gun return, so as to improve the accuracy of the gun return detection.
