3、否关闭：4、安全的装备中的光电 传感器工作是否正常。全部正常后气动设备的主电机开始工作。要求用 显示器显示各 个环节的检测信息，以方便用户查找设备无法正常启动的原因。2工程背景及需要解决的问题随着二十一世纪工业的迅速发展，工业生产早已走向自动化、智能化、集成化，各种集 成的全自动机械设备随处可见，而机械设备的启动控制则是任何机械设备中一个必经的 环境，大型机械设备的启动需要很多英他设备条件具备，否则无法正常启动设备，甚至 可能会造成意外的事故。因此，在设备启动前，应该对其它设备是否具备条件进行检测， 并将将检测结果送到启动设备，以控制设备的启停。而借助计算机虚拟程序控制，可以 高效准确的解决这

4、些问题。这就需要一个简单快捷的启动控制程序以及简易的硬件设施 及连线，来对检测结果进行判断，控制设备的启动，并能准确显示出异常项目，以便后 赛1 遍酷案：31所用到的实验设备8255芯片 一12864J液晶显示屏12864J少直动电机蜂鸣器3) LED灯、开关4个3 2翁统电路图和接线图JP79开哄LED蜂鸣器D直流电机8255芯片.LED灯、开关，直流电机以及蜂鸣器连线4控制程序4 - 1程序框图WR_DATA_AD _L EQU 0F006H RD.
