Just because of this, so it is widely used. Main research of this paper is that the part of control of the twodimension stepping singlechip microputer control workbench. The main task is to realize two stepping motor’s rotating positive and negatively and control of pace with singlechip microputer. The running steps are input by keyboard in this control system, displayed by the LED tube. The signal is transformed by singlechip microputer . The signal Loop allotter is achieved by software. The photoelectricity seclusion is achieved by Electrooptical disconnector. The signal is enlarged by power Amplifier. Then the signal can run the stepping motor. The system’s run is controlled by functional keys. Stepping motor will run to the given steps if the “start” key is pressed. Meanwhile, stepping motor will stop if the “stop” key is pressed. There are limit switches on the two heads of the workbench, if the workbench go beyond the terminal position, the limit switch is off, the stepping motor will be stop at once, and the buzzer scream. 完美畢業(yè)網(wǎng) 完美畢業(yè)網(wǎng) Keywords workbench stepping motor singlechip microputer 完美畢業(yè)網(wǎng) 完美畢業(yè)網(wǎng) 目錄 1 緒論 ............................................................................................................................................. 1 課題研究的背景 .................................................................................................................... 1 工作臺(tái)的發(fā)展現(xiàn)狀與方向 .................................................................................................... 1 本課題研究的范圍和意義 .................................................................................................... 3 步進(jìn)電機(jī)的發(fā)展現(xiàn)狀 ............................................................................................................ 3 單片機(jī)的發(fā)展現(xiàn)狀 ................................................................................................................ 4 2 控制系統(tǒng)的總體設(shè)計(jì) ................................................................................................................. 6 系統(tǒng)總體方案 ........................................................................................................................ 6 機(jī)械系統(tǒng) ................................................................................................................................ 6 控制系統(tǒng)設(shè)計(jì) ....................................................................................................................... 6 接口 設(shè)計(jì) .......................................................................................................................... 6 控制方案的選擇 .............................................................................................................. 7 伺服系統(tǒng)設(shè)計(jì) .................................................................................................................. 7 3 控制系統(tǒng)的設(shè)計(jì)方案 ................................................................................................................. 8 硬件系統(tǒng)設(shè)計(jì) ....................................................................................................................... 8 系統(tǒng)的硬件結(jié)構(gòu) .............................................................................................................. 8 步進(jìn)電機(jī) .......................................................................................................................... 8 微處理器的選擇 ............................................................................................................ 15 鍵盤操作的接口電路設(shè)計(jì) ............................................................................................ 17 顯示部分操作的接口和電路設(shè)計(jì) ................................................................................ 21 報(bào)警電路的設(shè)計(jì) ........................................................................................................... 24 單片機(jī)與 PC 機(jī)的通信 ................................................................................................ 25 系統(tǒng)的抗干擾設(shè)計(jì) ........................................................................................................ 26 軟件系統(tǒng)設(shè)計(jì) ..................................................................................................................... 28 軟件結(jié)構(gòu)設(shè)計(jì) ............................................................................................................... 28 系統(tǒng)的程序流程 ............................................................................................................ 29 結(jié)論 ............................................................................................................................................... 40 致謝 ................................................................
