Problems solved by technology

[0004] However, for the storage space of any device, its number of reads and writes is limited, and frequent reads and writes will damage the storage space of the device. Therefore, although the existing technology saves the position of the stepper motor in real time, it reduces the risk of hitting the wall. Frequency, but it brings the problem of reducing the service life of the device due to frequent reading and writing

Embodiment 1

[0036] figure 1It is a flow chart of a control method of a step-by-step drive structure provided by Embodiment 1 of the present invention. This embodiment is applicable to the equipment installed with a step-by-step drive structure to control the step-by-step drive structure installed therein. The case may be, for example, a case where a device mounted with a stepping drive structure performs position storage control of the stepping drive structure mounted therein. The method can be executed by a control device with a step-by-step drive structure or a device equipped with a step-by-step drive structure. The device can be implemented in the form of software and / or hardware, and can be integrated into a device equipped with a step-by-step drive structure. in the device. Optionally, it may be executed by a control running process that controls the stepper motor in the processing system of the device.

[0037] Optionally, the stepping driving structure in the embodiment of the p...

Embodiment 2

[0052] Figure 2AIt is a schematic diagram of the time axis of the information recording event provided by Embodiment 2 of the present invention. This embodiment is further optimized on the basis of the above embodiments, and specifically provides three different information recording events for detecting that the current moment reaches the preset recording cycle, detecting an external setting instruction, and detecting a system shutdown instruction , how to judge whether the current state parameters of the step-by-step drive structure meet the recording rules of the operation state information, and then introduce the specific situation of storing the operation state information of the step-by-step drive structure.

[0053] Among them, such as Figure 2A As shown, on this time axis, the preset recording cycle is T, point x to point x+T is one cycle, point x+T to point x+2T is the second cycle; point y and point z correspond to is the point of time when the external setting c...

Embodiment 3

[0098] image 3 It is a flow chart of a control method of a step-by-step drive structure provided by Embodiment 3 of the present invention. In this embodiment, the device equipped with a step-by-step drive structure provided in the above-mentioned embodiments corresponds to the step-by-step drive structure installed in it. On the basis of position storage, further optimization is carried out, and the specific situation of the stepping drive structure installed inside the device is initialized according to the operating status information stored in the storage space after the device is running is given. .

[0099] optional, such as image 3 As shown, the method specifically includes:

[0100] S301. A system start command is detected.

[0101] Wherein, the system startup instruction may refer to an instruction to control a startup device. The instruction can be generated by the user by triggering the power-on button on the device, or it can be an instruction to restart the d...

Abstract

The embodiment of the invention discloses a control method, device, equipment and storage medium of a stepping driving structure. The method includes: if an information recording event is detected, judging whether the current state parameters of the step-by-step driving structure meet the recording rules of the operating state information; if the current state parameters of the step-by-step driving structure meet the recording rules of the operating state information, then The current running status information of the stepping driving structure is replaced with the running status information stored in the storage space. The technical solution of the embodiment of the present invention greatly reduces the frequency of reading and writing of the operation state information of the step-by-step driving structure in the storage space on the premise of reducing the frequency of the equipment hitting the wall, and improves the service life of the equipment.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of drive control, and in particular, to a control method, device, equipment and storage medium for a step-by-step drive structure. Background technique [0002] Stepping drive structures, such as stepping motors, are widely used in medical equipment, automobiles, video surveillance and other equipment due to their advantages of low cost and high precision. First determine the initial position of the stepper motor. If the initial position cannot be determined, the stepper motor needs to be initialized by hitting the wall, and frequent wall hitting will seriously affect the service life of the equipment. [0003] At present, in order to accurately determine the initial position of the stepper motor, the device will record the real-time position of the stepper motor in its internal storage space during normal operation. When the device starts, if the recorded motor position can be read...
