Problems solved by technology

Therefore, because the control command was not received in time, there was no pulse to control the stepper motor, which caused the stepper motor to lose its step, so that the stepper motor could not run smoothly

Abstract

The embodiment of the invention provides a stepping motor control method, device and system and a storage medium. The method comprises the steps that: according to a preset period, before each presetperiod starts, motor operation information corresponding to the preset period is obtained, the motor operation information comprises a target pulse parameter and a preset pulse parameter, and according to the target pulse parameter, a stepping motor is controlled to rotate in the preset period; and if the motor operation information corresponding to the next preset period is not obtained before the next preset period of the preset period starts, the stepping motor is controlled to start to decelerate step by step in the next preset period according to the obtained preset pulse parameters untilnew motor operation information is stopped or received. Therefore, the out-of-step of the stepping motor due to the fact that the motor operation information is not obtained is avoided, and the stable operation of the stepping motor is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of stepping motors, in particular to a stepping motor control method, device, system and storage medium. Background technique [0002] With the advancement of industrial technology, stepper motors have been used more and more in many fields due to their good controllability. Especially in the field of security or video equipment, since the rotation angle of the stepping motor can be accurately controlled, the synchronous control of the stepping motor and the video frame of the captured video can be realized, and the target tracking of the dynamic target can be realized , or realize automatic zooming and other functions as the distance of the captured dynamic target changes. [0003] In order to realize the automatic protection of the stepper motor, after the stepper motor completes the rotation according to a control command, it will automatically mark the rotation to be executed in the next cycle a...
