机械设备的启动是工业生产中一个很常见的现象，而设备的启动往往不是按下按钮说开始就可以

了，很多的大型设备的启动是需要在很多其他设备等条件具备的情况下才可以进行的，比如很多的安全防护是否到位，一些压力值是否正常。如果这些无法保证就启动设备则很容易就造成安全事故，小则损坏设备，大则造成大的经济损失甚至人身伤害伤亡等，其后果不堪设想！因此在启动设备前，我们需要利用一些检测设备对这些需要保证的项进行检测，然后把这些检测结果送到启动设备中，判断是否具备启动条件！而这就需要一个好的启动控制程序，对检测结果进行判断，控制设备的启动。同时若有检测异常项目要能显示出异常项目，并报警，提醒工程人员进行检测！另外，在异常情况下，要能实现设备的停车。本项目就是针对机械设备的启动控制，进行硬件模拟，并实现软件的控制。

机械设备启动的计算机控制技术的实现

摘要：在一种大型机械加工设备的启动时，需要检测气源设备、液压设备、安全阀门和安全装备是否正常。如果四项检测项目均显示正常，则设备正常启动；如果四项检测项目中至少一项不正常，则设备不启动，通过显示屏显示故障所在，并进行警报。利用微机芯片8086，并行接口芯片8255以及显示屏模拟实现上述功能。

1. 项目题目概述及要求

1.1. 项目题目

某大型机械加工设备，启动过程需要检测以下装置：1、给设备供气的气源压力是否正常；2、液压系统的压力是否正常；3、安全门是否关闭；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

1.2. 项目要求

能够用检测到的信息控制设备的启动并显示正异常检测项

2. 工程背景及需要解决的问题

随着世界工业水平的发展，工业生产越来越走向自动化、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阶段，则控制程序的优劣关系到生产的效率及安全！很多的大型设备的启动是需要在很多其他设备等条件具备的情况下才可以进行的，比如很多的安全防护是否到位，一些压力值是否正常。如果这些无法保证就启动设备则很容易就造成安全事故，小则损坏设备，大则造成大的经济损失甚至人身伤害伤亡等，其后果不堪设想！因此在启动设备前，我们需要利用一些检测设备对这些需要保证的项进行检测，然后把这些检测结果送到启动设备中，判断是否具备启动条件！这就需要控制程序能够对检测设备输出进行判断，并以此控制机械设备的启动，同时要能显示正异常，能在存在异常项时及时报警，并及时停车。

3. 项目的模拟方案

3.1 启动控制的方案

1用8255作为总的调度，用5个开关分别代表总开关和四个检测项目，用液晶屏和5个LED灯分

别显示出总开关及4个检测项的检测情况！

2若总开关未开启，则灯全不亮！电机不转，蜂鸣器不响。

3总开关开启，检测项正常，则对应的灯亮，液晶屏显示对应项正常，否则对应灯灭，液晶屏显示

对应项异常。全正常则电机启动！

4只要存在检测项不正常，则电机停，蜂鸣器报警！

5循环检测

6用8155及数码管显示日期

3.2 模拟方案使用的芯片及模块

8255芯片、8155芯片 、12864J液晶显示屏 、段数码管 、直流电机、蜂鸣器 、开关、LED灯

5. 程序调试情况及运行结果分析

在程序调试过程中，遇到如下的几个问题：

1.在调试过程中，多次出现指针超出范围的问题。

解决：对各个子程序进行检查，先是检查了PUSH、POP语句是否规范，发现没有问题，后来发现在子程序结尾ret语句丢失，添加后运行正常。 2.在调试过程中出现range out的现象

解决：问题在于有条件跳转语句只能在短范围内跳转，不能跳转的范围太大，后来通过在跳转的范围中添加了一些中转站使问题得到解决。 3.在数码管显示，数码管始终无法显示

解决：起初以为问题出在实验箱，换了很多实验箱后问题仍然存在。最后发现是8155方式控制字的问题，其方式控制字与8255不同。

6. 项目的结论

项目的问题最终得到全部解决，通过改变输入，即利用开关控制输入检测项的正异常，程序能够判断检测项的正异常，并可正确显示出正异常项目，直流电机及蜂鸣器均能按照设想工作，数码管正常显示日期。

感言

通过这次项目，最大的感受就是累并快乐着，刚开始做的时候基本是一头雾水，首先对硬件根本不了解，对用软件控制硬件更是无从谈起！因为之前的微机原理实验时，课上的知识还没有学，所以实验本来要达到的熟悉硬件及了解软硬件的结合的目的没有达到！如是，项目开始的时候首先还是先做了下

实验，参照别人的程序，去了解如何用程序控制硬件！但书上对于硬件这一块的介绍还是偏少，软硬件的结合还是在调试过程中慢慢体会到的！之后开始构思整个项目，针对每一块功能进行设计，分块设计程序，分块进行调试。这一过程中，自学了8155，数码管，液晶屏！调试的过程很艰辛，因为程序比较大，加之很多自学的东西也不是特别了解，以及实验箱本身存在的问题，确实花了不少心血，跟着其他班去了很多次机房！做项目的过程中，老师对自己帮助很大，很多东西都是与老师和同学讨论出来的，团队合作能力得到锻炼。同时，查了很多资料，自学的能力也得到提高。这次项目我注意运用了这样一个科学的项目步骤“项目的优化与延伸，可行性可靠性分析，项目的执行，项目的评估”，深有体会，在答辩的时候也跟大家分享了一下！总之，花了不少时间，也学到了不少东西，成果还是不错的。
