Example Embodiment

[0020] Example: see figure 1 versus figure 2 This embodiment provides a stepping motor control method. A 16-bit single-chip microcomputer SPCE061A is used to control the stepping motor, and the sequential square wave output through the IO port is used as the control signal of the stepping motor; the control signal passes through the drive chip L298N Drive the stepping motor; at the same time, use the keyboard to control the state of the stepping motor, and use the digital tube to display the speed of the motor; and use the voice function of the Lingyang MCU to broadcast the speed of the stepping motor.

[0021] The nixie tube is a 4-bit nixie tube, 74LS164 is used as the display driver of the 4-bit nixie tube, and a signal is input from the 16-bit single-chip microcomputer SPCE061A. The keyboard is a 4x4 matrix keyboard. The stepper motor is one of a reactive stepper motor, a permanent magnet stepper motor and a hybrid stepper motor. The stepping motor is a four-phase stepping...

Abstract

The invention discloses a stepping motor control method and a control device implementing the stepping motor control method. The control device comprises a 16-bit single chip microcomputer SPCE061A, a drive chip L298N, a keyboard, a Sunplus single chip microcomputer and a 74LS164 device, wherein the drive chip L298N, the keyboard, the Sunplus single chip microcomputer and the 74LS164 device are connected with the single chip microcomputer SPCE061A. The drive chip L298N and a stepping motor are connected with the single chip microcomputer SPCE061A, and the 74LS164 device is connected with a nixie tube. The stepping motor control method is easy to achieve, simple and convenient to operate and simple in control step. The control device is simple and reasonable in whole circuit design, small in size and convenient to use and control, the problem of miniaturization of the stepping motor is solved, and the accuracy of the stepping motor is improved. In addition, the control device has a displaying function and a voice function, so that an operator can conveniently know a working state of the stepping motor at any time, the working quality is effectively improved, the work efficiency is improved, and large-scale popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of stepping motor control, and in particular relates to a stepping motor control method and a control device for implementing the method. Background technique [0002] Stepper motors were first developed by the British in the 1920s. The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or motion. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it will drive the stepper motor to press The set direction rotates at a fixed angle, and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning, and at the same time, the speed and acceler...
