The method and device for maintaining a gun for returning a charging pile provided by the embodiment of the present application can be applied to a charging pile. As shown in FIG. 1 , the charging pile 10 includes a controller 11 and a gun seat 100 , and the charging pile 10 is connected to the charging gun 20 ; The gun seat 100 provided on the pile 10 enables the charging gun 20 to be inserted into the gun seat 100 to realize the user returning the gun; the gun seat 100 is provided with a distance sensor, and the gun head of the charging gun 20 is provided with an ultrasonic or infrared signal transmitting module , the distance sensor and the ultrasonic or infrared signal transmitting module constitute a gun return detection module. The distance sensor on the gun base 100 can detect the signal strength on the gun head. When the gun head of the charging gun 20 is closer to the gun base, the signal detected by the distance sensor The greater the strength, when the signal strength value detected by the distance sensor is greater than the threshold of returning the gun, it is considered that the gun is returned successfully; when the tip of the charging gun 20 is farther from the gun seat, the signal strength detected by the distance sensor is smaller, when the distance sensor When the detected signal strength value is less than the threshold of pulling the gun, it is considered that the pulling of the gun is successful, and when the charging gun is connected to the charging port of the electric vehicle after pulling the gun, so that the charging pile is in the charging state, the signal strength value detected by the distance sensor minimum.

Please refer to FIG. 2 , which is a schematic flowchart of an embodiment of a method for returning a gun for maintenance of a charging pile of the present application. The method can be executed by the controller 11 in the charging pile, and the method includes steps S201 to S203 .

S201: When the charging pile is in a charging end state, obtain a first gun return signal value of the gun seat.

When the user needs to use the charging gun to charge the electric vehicle, as shown in FIG. 3 , the user’s smart terminal 30 is connected to the charging pile 10 in communication, and the smart terminal 30 is provided with an application program related to the control of the charging pile 10 . The application program on 30 can send some control commands to the charging pile 10, for example, start charging commands and/or stop charging commands. When the charging pile 10 receives the start charging instruction sent by the intelligent terminal 30, if the charging gun 20 is connected to the charging port of the electric vehicle, the electric vehicle starts to be charged; when the charging is completed, or the user sends a stop charging instruction through the intelligent terminal 30 to When the charging pile is 10, the charging order is completed and it is in the charging end state. Therefore, the charging end state detected by the charging pile 10 may be the case where the user uses the charging gun to complete the charging order for the electric vehicle.

When the charging pile is in the charging end state, the controller 11 of the charging pile 10 acquires the first gun return signal value of the gun holder 100 after a period of time (eg, half a minute) after the charging is completed. Since the user may not insert the charging gun 20 back into the gun holder 100 in time after charging, the charging pile 10 can set the period of time to give the user the opportunity to return the gun in time, so as to avoid the immediate detection and return of the gun as soon as the order is completed. The detection is inaccurate due to the gun signal value.

Then, the controller 11 of the charging pile 10 judges the value of the first gun return signal. If the first gun return signal value is less than the gun return threshold Tr1, the charging pile 10 judges that the charging gun is in the state of not returning the gun. At this time, the charging pile 10. Send the prompt information to the smart terminal 30, the prompt information is used to prompt the user that the gun has not been returned; the smart terminal 30 is used to return the feedback information of the returned gun.

Correspondingly, if the value of the first gun-return signal 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 the threshold value does not need to be adjusted. At this time, the gun-return state is maintained. Threshold and draw threshold.

S202: If the feedback information of the returned gun is received, and the value of the first gun return signal is updated to the second gun return signal value, determine whether the second gun return signal value is smaller than the gun return threshold.

Specifically, when the charging pile sends a prompt message to the smart terminal, the user sees the prompt message and will perform a corresponding operation, otherwise the order will be in an unfinished state. If the user confirms that he has returned the gun, the user can click the "Returned Gun" button in the application of the smart terminal, and then the charging pile receives the feedback information of the returned gun. If the position of the charging gun has not changed, the gun The value of the first gun return signal detected by the seat is maintained; if the position of the charging gun changes, the first gun return signal value detected by the gun seat will be updated to the second gun return signal value. Alternatively, if the user finds that he has not returned the gun, the user can also click the "Returned Gun" button in the application program of the smart terminal, and the user inserts the charging gun into the gun seat, at this time, the first gun return signal value will be It is updated to the signal value of the second gun returned, and the charging pile will also receive the feedback information of the returned gun.

After the first gun return signal value is updated to the second gun return signal value, the charging pile determines whether the second gun return signal value is smaller than the gun return threshold. By judging whether the second gun return signal value is less than the gun return threshold, it can be determined whether the gun return detection module on the gun seat of the charging pile is working normally. Return the gun, resulting in poor user experience, so it is necessary to correct the failure of the gun return module.

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.

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 "successfully returned the gun" to the intelligent terminal .

It can be understood that, to judge whether the second gun return signal value is not less than the gun return threshold value, the charging pile can be set to a preset duration, and the preset duration can be two minutes, within two minutes to determine whether the second gun return signal value V2 is If it is greater than or equal to the gun return threshold Tr1, or the second gun return signal value V2 changes to be greater than or equal to the gun return threshold Tr1, 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, It is the user who forgot to return the gun. At this time, no threshold update processing is required.

S204: If the second gun return signal value is smaller than the gun return threshold, determine that the gun return is abnormal, and re-determine the gun return threshold and/or the gun draw threshold.

Specifically, if the second gun-return signal value is less than the gun-return threshold, it means that the gun-return detection module is abnormal. At this time, the charging pile determines that the gun-return is abnormal, and re-determines the gun-return threshold and/or the gun-draw threshold.

It should be noted that, to determine whether the second gun return signal value is less than the gun return threshold, the charging pile can be set with a preset duration, and the preset duration can be two minutes, that is, to determine whether the second gun return signal value V2 is within two minutes. is smaller than the gun return threshold Tr1, or is continuously less than the gun return threshold Tr1, if the second gun return signal value V2 is smaller than the gun return threshold Tr1, or is continuously smaller than the gun return threshold Tr1, it indicates that the gun return is abnormal, and the trigger threshold is updated. Thresholds include return thresholds and/or draw thresholds.

In some of these implementations, re-determining the shot return threshold may include:

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

subtracting the gun draw threshold from the first difference to obtain a second difference;

If the second difference value is greater than or equal to a second preset constant value, updating the gun return threshold value to the first difference value.

Specifically, when the charging pile determines that the gun return detection module is abnormal, the first preset constant value is subtracted from the second gun return signal value to obtain the first difference value. The second gun return signal value is represented by V1, and the first The preset constant value is represented by Tr_CONST, and the first difference value is represented by Tr1', therefore, Tr1'=V1-Tr_CONST.

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

Determine the relationship between the second difference value 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 value 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 realize the normal detection of the gun return. Therefore, The return threshold is updated to the first difference, that is, Tr1=Tr1'.

It is understandable that due to hardware differences and considering the problems of device aging during subsequent use, the signal strength value of the charging pile and the charging gun when the gun is pulled out of the factory cannot be directly used as the threshold. On the basis of the signal strength value, an offset is superimposed as a threshold. Therefore, the offset is the first preset constant value Tr_CONST; the second preset constant value Tr_Delta_Min is the return threshold Tr1 and the withdrawal threshold Tr2. The minimum difference that needs to be maintained between the thresholds.

In some embodiments, after the first difference is subtracted from the gun-drawing threshold to obtain the second difference, the method further includes:

Obtain the minimum value of the gun drawn, which is the signal strength value of the charging gun detected by the obtained gun seat when the charging pile is in a charging state;

subtracting the minimum value of the drawn gun from the first difference to obtain a third difference;

If the second difference value is less than the second preset constant value, and the third difference value is less than or equal to the sum of the first preset constant value and the second preset constant value, maintaining the Return the gun threshold and determine that the distance sensor on the gun mount is damaged.

Specifically, after obtaining the second difference, in order to further determine whether the distance sensor on the gun seat is damaged, first obtain the minimum value V2_Min of the gun drawn, and the minimum value of the gun drawn is the obtained gun seat when the charging pile is in the charging state. The detected signal strength value of the charging gun, that is, when the charging gun is inserted into the electric vehicle for charging, the signal strength value detected by the gun seat is the minimum value of the drawn gun. Then, the minimum value of the drawn gun is subtracted from the first difference to obtain a third difference, that is, the third difference=Tr1'-V2_Min; if the second difference is smaller than the second preset constant value, and the The third difference value 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 value Tr1'-Tr2<Tr_Delta_Min, and Tr1'-V2_Min≤Tr_Delta_Min+Tr_CONST , it means that the gun return detection module is damaged and the detection is inaccurate. At this time, it is not necessary to re-determine the gun return threshold and/or the gun withdrawal threshold Tr1, maintain the gun return threshold Tr1, and the charging pile determines that the distance sensor on the gun seat is damaged .

In some of the embodiments, the charging pile is connected in communication with the smart terminal; after the determining that the distance sensor on the gun base is damaged, the method further includes:

Sending the damaged information of the distance sensor to the smart terminal.

After the charging pile determines that the distance sensor is damaged, the charging pile sends the damage information of the distance sensor to the smart terminal, and the smart terminal displays the failure of the gun return module, so that the user can get the information of the failure of the gun return module. The gun module is faulty, alerting the user.

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

In some of these embodiments, after obtaining the third difference, the method further includes:

If the second difference value is less than the second preset constant value, and the third difference value is greater than the sum of the first preset constant value and the second preset constant value, the additional The gun threshold is updated to the first difference, and the gun draw threshold is updated to the sum of the minimum gun draw and a first preset constant value.

Specifically, after obtaining the third difference value, if the second difference value Tr1'-Tr2 is smaller than the second preset constant value Tr_Delta_Min, that is, Tr1'-Tr2<Tr_Delta_Min, and the third difference value is greater than the first preset constant value The sum of the numerical value and the second preset constant value, that is, Tr1'-V2_Min>Tr_Delta_Min+Tr_CONST, it means that the gun return detection module is not damaged, but the threshold is not enough to satisfy the judgment of returning the gun or drawing the gun, so the return threshold and The threshold for pulling the gun needs to be updated. At this time, the threshold for returning the gun is updated to the first difference, that is, Tr1=Tr1'; and the threshold for pulling the gun is updated to the sum of the minimum value of the gun and the first preset constant value, that is, Tr2 =V2_Min+Tr_CONST.

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