The monolithic integrated circuit to stepbysteps the electrical machinery control to have the serial control and parallel controls two design uses the serial control mode, under this way the monolithic integrated circuit control system with stepbysteps between the electrical machinery driver only then two pilot out the clock pulse signal to control stepbysteps the electrical machinery rotational speed。 When needs to accelerate the movement, sends out the control pulse which the frequency increases progressively。 When needs to lock the condition, only needed to stop sending the pulse and passing over the direct current to be possible. Key words: Singlechip microputer system； Control。 ring distributor 東華理工 大學(xué)長(zhǎng)江學(xué)院畢業(yè)設(shè)計(jì)（論文） 目錄 目 錄 緒論 ................................................................................................................... 1 引言 ................................................................................................... 1 步進(jìn) 電機(jī)驅(qū)動(dòng)技術(shù)發(fā)展 ........................................................... 1 國(guó)外驅(qū)動(dòng)器發(fā)展概況 ............................................................... 1 國(guó)內(nèi)驅(qū)動(dòng)器概況 ....................................................................... 2 步進(jìn)電機(jī)驅(qū)動(dòng)軟件的發(fā)展?fàn)顩r ............................................... 3 提出問(wèn)題 ............................................................................................ 3 列舉設(shè)計(jì)方案 .................................................................................... 3 確定設(shè)計(jì)方案 .................................................................................... 4 明確課題任務(wù) ........................................................................... 4 確定設(shè)計(jì)方案 ........................................................................... 4 研究?jī)?nèi)容和方法 ................................................................................ 5 研究?jī)?nèi)容 ................................................................................... 6 研究方法 ................................................................................... 6 課題研究的意義 ................................................................................. 6 第 2 章 三相反應(yīng)式步進(jìn)電機(jī)及硬件電路 ..................................................... 8 步進(jìn)電動(dòng)機(jī)概述 ................................................................................ 8 三相反應(yīng)式 步進(jìn)電機(jī)的結(jié)構(gòu)和原理 ................................................ 8 單片機(jī)對(duì)步進(jìn)電機(jī)的控制原理 ........................................................ 9 硬件電路的組成部分 ......................................................................... 9 第 3 章 控制系統(tǒng)軟件設(shè)計(jì) ........................................................................... 10 軟件設(shè)計(jì)思想 .................................................................................. 10 程序流程圖 ...................................................................................... 10 正反轉(zhuǎn)程序流程圖 ................................................................. 10 加減速控制程序流程圖 ..........................................................11 鍵輸入程序流程圖 ................................................................. 13 定時(shí)器中斷服務(wù)程序流程圖 ............................................... 14 步進(jìn)電機(jī)驅(qū)動(dòng)子程序流程圖 ................................................. 15 數(shù)碼管顯示程序流程圖 ......................................................... 16 程序清單 .......................................................................................... 17 主程序設(shè)計(jì) ............................................................................. 17 步進(jìn)電機(jī)驅(qū)動(dòng)子程序設(shè)計(jì) ..................................................... 17 正向運(yùn)行的子程序 .................................................................. 19 反向運(yùn)行子程序 ...................................................................... 19 8255 初始化程序 ..................................................................... 19 數(shù)碼管顯示子程序 .................................................................. 20 加減速控制 程序 ................................................................... 20 位控制 程序 ........................................................................... 21 定時(shí)器中斷服務(wù)子程序 ....................................................... 21 鍵輸入程序 ........................................................................... 22 去鍵抖動(dòng)程序 ....................................................................... 23 東華理工 大學(xué)長(zhǎng)江學(xué)院畢業(yè)設(shè)計(jì)（論文） 目錄 第 4 章 控制系 統(tǒng)可靠性設(shè)計(jì) ....................................................................... 26 抗干擾措施設(shè)計(jì) .............................................................................. 26 軟件抗干擾措施 ........................................................................... 26 第 5 章 不足與展望 ....................................................................................... 27 致 謝 ...............................................
