Control system of stepping motor and control method thereof

Abstract

The invention relates to a control system of a stepping motor. The control system comprises a three-phase stepping motor, a driving circuit, a photoelectric isolation circuit and a controller of the stepping motor, wherein the controller of the stepping motor comprises an annular distributor, a speed setting circuit, a working mode setting circuit, a beat initialization circuit, an operation switch and an operation indicating circuit, and the annular distributor can realize the functions by simulating a D flip-flop and a data selector through a single-chip microcomputer. The control system adopts the D flip-flop chip and the data selector chip to design the annular distributor, the circuit is simple in structure, and the idea is clear and easy to understand; and a method of combining software and hardware is adopted for realizing the functions of the annular distributor, and the single-chip microcomputer can simultaneously complete the functions of data acquisition and processing, thereby being an original creation. Simultaneously, circuit experiment teaching with the combination of a digital-electronic technology and curriculum knowledge of the single-chip microcomputer can practice the comprehensive design capability of students, improve the utilization rate of equipment in a laboratory and avoid the waste of resources in the laboratory.

Description

technical field [0001] The invention belongs to the technical field of stepping motor control, and in particular relates to a stepping motor control system and a control method thereof, which are used for circuit experiment teaching in laboratories of colleges and universities. Background technique [0002] At present, in colleges and universities, laboratory construction is booming, and there are various types of experimental equipment, but there is no correlation between them, and they are independent of each other. The distributor is mainly composed of flip-flops, counters and combination circuits. These circuit experiments are experiments in digital electronic technology courses. These two kinds of experimental equipment are distributed in different laboratories, which will result in low equipment utilization and waste of resources. Existing equipment cannot meet the comprehensive design ability of students. [0003] Currently in the electrical major of the university, ...

Problems solved by technology

At present, ring distributors are mainly composed of D flip-flops and complex gate circuits, or counters and complex gate circuits. Their biggest disadvantage is that the circuits are complex and impractical.

The ring distributor can be realized by single-chip software or digital circuit, but it is rare to use the combination of software and hardware to realize the function of the ring distributor.
