Driving controller of stepping motor

Abstract

The invention relates to a driving controller of a stepping motor, structurally comprising a stepping motor control circuit and a stepping motor drive circuit which are integrated on a circuit board, wherein the stepping motor control circuit comprises a programmable CPU chip, a typical peripheral working circuit thereof, a communication port extending chip and a communication interface, wherein the programmable CPU chip extends the communication interface with an upper computer through the communication port extending chip and is solidified with working software and an identification number or an address number; the stepping motor drive circuit comprises a stepping motor drive chip, a typical peripheral working circuit thereof and a stepping motor interface, wherein enabling, pulse and direction pins of the stepping motor drive chip are connected with the I / O (Input / Output) port of the programmable CPU chip; and the stepping motor interface is directly led out by the stepping motor drive chip. The invention has the advantages of intelligence, programmability, simple structure, low cost and convenient operation, greatly reduces the working loads of the upper computer and is easy to realize the control and the remote control of a plurality of stepping motors.

Description

technical field [0001] The invention relates to a stepping motor, in particular to a stepping motor drive controller, which is mainly used in occasions requiring intelligent and precise control, such as precision instruments, industrial control systems and other fields. It is also widely used in spraying equipment, medical instruments and equipment, etc. Complete the adjustment and control of the speed, direction and steps of the stepper motor. Background technique [0002] For the control and drive of stepper motors, most of them are currently controlled by single-chip microcomputer combined with special chips for stepper motors, which is similar to the structure of p207 in "Practical and Application of Single-chip Microcomputer 8051", ("Practical and Application of Single-chip Microcomputer 8051", edited by Yang Zhonghuang et al., China Water Conservancy Hydropower Press, June 2001); or control by connecting the computer external expansion interface card with the stepper ...

Problems solved by technology

[0005] 2. The host computer has a large workload

[0006] 3. It is difficult to realize multiple stepper motors or remote stepper motor control

On the one hand, for the control of multiple motors, the software structure of the single-chip microcomputer or computer expansion interface card is complicated; on the other hand, due to signal attenuation, it is difficult for the single-chip microcomputer or computer expansion interface card to remotely control the stepping motor
