[0020] The embodiment of the present application provides a fault handling method, device, equipment and medium. In the embodiment of the present application, if the PI level corresponding to the target stepper motor of the target lens is identified to be abnormal, the correction step length corresponding to the saved target stepper motor is obtained; wherein the correction step length is used to determine the correct PI position; the target stepper motor is controlled to move to a first preset position, and the target stepper motor is controlled to move in a preset direction according to the correction step length; the position of the target stepper motor after the movement is updated to the PI position corresponding to the target stepper motor, and the PI position is determined as the reference point corresponding to the target stepper motor. Embodiment 1:

[0021] Figure 1 A schematic diagram of a fault handling process provided in an embodiment of the present application, the process includes: S101: If it is identified that the PI level corresponding to the target stepping motor of the target lens is abnormal, then the saved correction step length corresponding to the target stepping motor is obtained; wherein the correction step length is used to determine the correct PI position.

[0022] A fault handling method provided in an embodiment of the present application is applied to an electronic device, which may be a camera, a server, etc.

[0023] In the embodiment of the present application, the camera is powered on and a routine lens self-check is performed. If an abnormal PI level corresponding to the target stepper motor of the target lens of the camera is identified, it means that a PI abnormality has occurred in the camera and the camera needs to be troubleshooted to avoid problems such as camera out-of-focus that affect normal use.

[0024] Among them, the PI level is abnormal but not limited to the level on both sides of the PI position corresponding to the stepper motor being consistent. For example, if the level on one side of the PI position is high, the other side is also high; or, if the level on one side of the PI position is low, the other side is also low.

[0025] Based on this, in an embodiment of the present application, a correction step length corresponding to each stepper motor is pre-stored in the electronic device, and the correction step length is used to adjust the PI position of the target lens so that the target lens has a correct PI position.

[0026] In a possible implementation, if the electronic device recognizes that the PI level corresponding to the target stepper motor of the target lens is abnormal, the electronic device obtains the saved correction step length corresponding to the target stepper motor, and adjusts the PI position in the target lens based on the correction step length.

[0027] S102: Control the target stepper motor to move to a first preset position, and control the target stepper motor to move in a preset direction according to the correction step length; update the position of the target stepper motor after movement to the PI position corresponding to the target stepper motor, and determine the PI position as the reference point corresponding to the target stepper motor.

[0028] In an embodiment of the present application, the electronic device first controls the target stepper motor to move to a first preset position, and then controls the stepper motor to move from the first preset position to a preset direction, and the moving step length is the acquired repair step length.

[0029] In a possible implementation, the camera includes one or more stepper motors, each stepper motor controls a group, and the electronic device drives the lens in the group controlled by the stepper motor to move to the first preset position by controlling the rotation of the target stepper motor.

[0030] Generally, the first preset position is the mechanism end of the group controlled by the target stepper motor, and the mechanism end is a physical boundary, that is, the first preset position is the boundary of the group controlled by the target stepper motor.

[0031] After the electronic device controls the target stepper motor to move to the first preset position, the electronic device controls the target stepper motor to move the correction step length in a preset manner, and updates the position of the target stepper motor after the movement to the PI position corresponding to the target stepper motor. The electronic device determines the PI position as the reference point corresponding to the target stepper motor.

[0032] In the embodiment of the present application, if the PI level corresponding to the target stepper motor of the target lens is identified to be abnormal, the correction step length corresponding to the saved target stepper motor is obtained; the target stepper motor is controlled to move to a preset position, and the target stepper motor is controlled to move in a preset direction according to the correction step length; the position of the target stepper motor after the movement is updated to the PI position corresponding to the target stepper motor. When there is a PI abnormality, the stepper motor can be quickly and reliably moved to the correct PI position according to the correction step length, thereby improving the defocus problem caused by the PI abnormality, so that the camera can obtain a clear image through the PI position corresponding to the adjusted motor, and achieve accurate zoom or focus.

[0033] Embodiment 2:

[0034] In order to avoid the camera out-of-focus problem caused by PI abnormality, so that the camera can capture clear images and achieve accurate zooming or focusing, based on the above embodiment, in the embodiment of the present application, if it is identified that the PI level corresponding to the target stepping motor of the target lens is normal, the method further includes: Controlling the target stepping motor to move to the first preset position; Controlling the target stepper motor to move along the preset direction and detecting the PI level corresponding to the target stepper motor until the PI level changes; The step length that the target stepping motor has currently moved is determined, and the saved correction step length is updated using the moved step length.

[0035] In the embodiment of the present application, when the electronic device recognizes that the PI level corresponding to the target motor of the target lens of the camera is normal, the electronic device can update the correction step length corresponding to the target stepping motor.

[0036] The corrected step length is used to determine the correct PI position, and the PI position is the position where the high and low levels jump. Based on this, the electronic device can control the target stepper motor to move from a fixed position, and query the PI level jump corresponding to the target stepper motor in real time during the movement. When the PI level jump is detected, the electronic device counts the step length of the target stepper motor and updates the moved step length to the corrected step length.

[0037] It should be noted that after the electronic device updates the correction step size, if the target stepper motor needs to adjust the PI position based on the updated correction step size, the starting moving position of the target stepper motor during adjustment needs to be consistent with the starting moving position when the correction step size is updated.

[0038] Generally, the initial moving position of the electronic device when updating the correction step length is the first preset position.

[0039] In one possible implementation, the electronic device controls the target stepper motor to move to a first preset position; controls the target stepper motor to move along a preset direction and detects a PI level corresponding to the target stepper motor until the PI level changes; determines the step length that the current target stepper motor has moved, and uses the moved step length to update the saved corrected step length.

[0040] In the embodiment of the present application, if there is no PI abnormality in the target stepper motor, the current PI position of the target stepper motor is the position where the PI level changes. Based on this, in order to improve the efficiency of updating the corrected step size, the electronic device can control the target stepper motor to move to the left side of the PI position at a faster speed, and then control the target stepper motor to move at a slower speed until the PI level changes.

[0041] In addition, in an embodiment of the present application, when the electronic device updates the correction step size corresponding to the target stepper motor, it can repeat the above-mentioned steps of determining the position from the first preset position to the position where the PI level changes, determine multiple moved step sizes, and determine the average value of the multiple moved step sizes. The electronic device uses the average value to update the saved correction step size corresponding to the target stepper motor.

[0044] In order to control the target stepper motor to move quickly and accurately to the first preset position and to avoid collision, in an embodiment of the present application, the electronic device can first control the target stepper motor to move to a position close to the first preset position at a faster speed and then slowly move to the first preset position.

After the target stepper motor moves to the second preset position, the electronic device controls the target stepper motor to move from the second preset position to the first preset position at a second speed; wherein the second speed is less than the first speed.

[0046] Generally, the second preset position is the optical end of the group controlled by the target stepper motor, and the optical end is the effective stroke boundary of the software control. That is, the first preset position is the boundary that can be reached by the software control.

[0047] In a possible implementation, the electronic device controls the target stepper motor to rotate at a first speed, driving the lens in the group controlled by the target stepper motor to move to the optical end, and after the electronic device recognizes that the lens has moved to the optical end, the electronic device controls the target stepper motor to rotate at a second speed, driving the lens from the optical end to the mechanism end. Wherein, the optical end and the mechanism end are located on the same side of the PI position, if the optical end is the left optical end, the mechanism end is the left mechanism end; if the optical end is the right optical end, the mechanism end is the right mechanism end.

[0048] In another possible implementation, when the electronic device updates the corrected step length of the target stepper motor, the electronic device may also control the target stepper motor to rotate to the left of the PI position at a first speed, and then control the target stepper motor to rotate at a second speed until the PI level changes. When the electronic device controls the target stepper motor to rotate to the left of the PI position at a faster speed, the step length of the target stepper motor may be the distance from the second preset position to the current PI position.

Control the zoom motor to rotate to the left, and the moving steps are, where is an empirical value, which can be adjusted according to the individual differences of the lens, and the value range is ≥1.5.

[0051] It should be noted that in the embodiment of the present application, the number of steps m from the left optical end B to the left mechanism end A stored in the electronic device is considered to be inaccurate, and therefore increased.

[0052] 2. Control the target stepper motor to rotate to the right, using a large step length and a fast moving step number n; that is, control the target stepper motor to rotate to the right at a first speed, n steps.

[0053] 3. Adjust the step length of the target stepper motor and continue to move rightward with the minimum step length, that is, control the target stepper motor to rotate to the right at the second speed. During the movement, query the PI level jump corresponding to the target stepper motor in real time, and stop immediately when the PI level becomes a low level, and record the number of steps m' of this movement.

[0054] 4. Determine the modified step size of the target stepper motor after update as X zoom =n+m'.

[0055] On this basis, if the electronic device determines that the PI level of the target stepper motor corresponding to the group is abnormal, the electronic device updates the PI position based on the correction step length in the following manner: 1. Control the target stepper motor to rotate to the left, and the number of steps is, where is an empirical value with a value range of ≥1.5.

[0056] 2. Control the target stepper motor to rotate to the right, and the number of steps is the correction step length X of the target stepper motor. zoom .

[0057] 3. After the target stepper motor rotates to the right position, update the current position to the PI position of the target stepper motor.

[0059] In the embodiment of the present application, the electronic device uses a lens self-check method to determine whether there is a PI abnormality.

[0060] Specifically, a lens self-check method is used to determine the reference point corresponding to each stepper motor of the target lens; wherein the reference point is the position where the level of the stepper motor jumps; if the reference point corresponding to the target stepper motor is not obtained, it is determined that the PI level corresponding to the target stepper motor is abnormal.

If there is at least one abnormality in the PI level of the zoom and focus motors, control the motor with the abnormal PI level to rotate to the corresponding left mechanism end, control the motor with the abnormal PI level to move to the right by its corresponding correction step length, and update the current position to the PI position of the motor with the abnormal PI level. In an embodiment of the present application, by calculating the correction step length from the lens PI position to the mechanism end, the PI position of the motor can be quickly and reliably corrected in the event of a PI failure, thereby improving the out-of-focus problem caused by the inability to accurately determine the position of the stepper motor.
