提出了一個(gè)由AT89C52單片機(jī)控制步進(jìn)電機(jī)的實(shí)例。可以通過(guò)鍵盤(pán)輸入相關(guān)數(shù)據(jù), 并根據(jù)需要, 實(shí)時(shí)對(duì)步進(jìn)電機(jī)工作方式進(jìn)行設(shè)置, 具有實(shí)時(shí)性和交互性的特點(diǎn)。該系統(tǒng)可應(yīng)用于步進(jìn)電機(jī)控制的大多數(shù)場(chǎng)合。實(shí)踐表明, 系統(tǒng)性能優(yōu)于傳統(tǒng)的步進(jìn)電機(jī)控制器。關(guān)鍵詞: 單片機(jī); 步進(jìn)電動(dòng)機(jī); 直流固態(tài)繼電器; 實(shí)時(shí)控制Con trol System of Stepp ingMotor Ba sed on AT89C52 ChipM icrocomputerMENGWu2sheng, L ILiang (College of Automatization, Northwestern Polytechnical Unversity, Xipan 710072, China)ABSTRACT: A stepp ing motor control system based on AT89C52 chip microcomputer was described.The data can be inputwith keyboard, and stepp ingmotorwas controlled by these data. According to the demand, users can set the workingmodel of stepp ingmotor in real2time. This system can be widely used in stepp ing motor controlling. The p ractice showed that the performance of this system outdid the tradi tional stepp ing motor controller.KEY WORDS: Chip microcomputer; Stepp ingmotor; DCSSR; Real2time control
