1、课程设计报告彩灯广告屏的PLC控制学院： 信息工程学院班级： 08建筑设施智能技术一班姓名： 崔兴 （2008551425） 陆建朋（2008551428） 李杰 （2008551423） 指导老师：张仲模完成时间：2011年6月20日 一、引言 （一）摘要：本次课程设计主要目的是掌握可编程序控制器（PLC）的基本工作原理、指令系统、硬件连接，学会使用可编程序控制器的基本方法，锻炼PLC编程能力，学会用PLC解决电气控制问题。本次课程设计我们选的题目是彩灯广告屏的PLC控制。要求编写PLC程序控制彩灯按一定要求亮灭。二、课程设计要求1. 设计任务：用PLC控制一个彩灯广告屏。2. 控制要求 广

2、告屏中间有8根彩灯管，编号18，启动后，点亮的顺序为1号依次到8号，间隔2s，全亮10s后，按8号到1号顺序开始熄灭，间隔1s。全部熄灭后，等待2s，再开始一个循环。 广告屏周围安装6组灯，给它编号。启动后，按照16的顺序隔2s依次点亮。全亮20s，然后依次熄灭。全熄灭5s后，下一个循环从6到1号，隔2s依次点亮。然后开始新的循环 可以2组同时工作，也可以单独工作。3. 设计内容：1）计算输入输出点，编写I/O对应表及内部元件使用表；2). 编写PLC控制程序；要求可以实现单步、单周期及连续工作3种操作方式。3）完成实验所需要的硬件接线；4）利用实验台上的开关、按钮、小指示灯等，模拟演示其工作

3、过程；5）完成课程设计报告。三、课程设计内容1、设计过程和有关说明： 根据要求要实现单步，单周期，连续工作，并且能分组进行单独工作，加上启动停止，共设置了8个按钮。输出由Q0.0-Q0.7表示广告屏中间的8根彩灯管。Q1.0-Q1.5表示广告屏周围的6组灯。（1）I O对应表及内部元件使用表如下：输入表序号名称输入点序号名称输入点1启动I0.052组单独运行I0.42停止I0.161组单独运行I0.53单步开关I0.27两组同时运行I0.64连续单周期I0.38单步按钮I0.7输出表序号名称输出点序号名称输出点1一组1号Q0.08一组8号Q0.7待添加的隐藏文字内容22一组2号Q0.19二组1

5、制要求，对M0.1进行控制就能达到单步，单周期和亮灭时间的控制目的。2、PLC程序如下： 四、设计心得及程序调试过程1，设计过程设计过程中上网查阅了相关资料，确定了以移位寄存器为主要逻辑手段，以控制秒脉冲来实现各种控制要求。我们根据实际要求，分析只要做出一组灯，第第二组灯也是同样的逻辑，然后我们先没有考虑功能的实现，只对一组灯的逻辑进行了一个简单的实现。经过对单周期，单步概念的理解，进而做出了相应的功能。最后整体在实验台上操作以后进行了进一步的改进，最终实现了所要求的效果。2，设计心得崔兴：本次课程设计，在实验室待了几天，虽然PLC的知识是上个学期学习的，不过翻翻书以后大部分都记起来了，先是对

6、课程设计的要求做了一个简单的分析，然后是初步构思了一个简单逻辑程序，单纯的实现了灯的亮灭顺序，而后在进一步设计功能时，经过多番讨论终于设计出比较合理的方案。然后再反复的调试，最终成功。实验室待的几天，感觉自己学的东西总算有些用途，同时我还跟其他组做其他课题的同学讨论了他们的程序，学到了更多的东西。不过，拿我们写的程序跟现实生活中的设计要求来比较之后，又发觉还有更多需要学习的地方。总的来说，这次设计让我对理论和实际有了一个比较和认识，也让我知道，要想明白更多事情，必须不断的把理论放在实践中去。陆建朋：两周的课程设计结束了，在这次的课程设计中不仅检验了我所学习的知识，也培养了我如何去把握一件事情，

7、如何去做一件事情，又如何完成一件事情。在和小组成员的合作中，我收获颇丰。我懂得了每个人都可以做得更加好，如果能够在和他人合作的过程中充分发挥自己。 课程设计是我们专业课程知识综合应用的实践训练，着是我们迈向社会，从事职业工作前一个必不少的过程”千里之行始于足下”，通过这次课程设计，我深深体会到这句千古名言的真正含义我今天认真的进行课程设计，学会脚踏实地迈开这一步，就是为明天能稳健地在社会大潮中奔跑打下坚实的基础通过这次plc彩灯设计，本人在多方面都有所提高。通过这次设计，综合运用本专业所学课程的理论和生产实际知识进行彩灯循环设计工作的实际训练从而培养和提高学生独立工作能力，巩固与扩充了plc设

8、计等课程所学的内容，掌握plc设计的方法和步骤，掌握plc设计的基本的技能。怎样确定工作原理，了解了一些软件，独立思考的能力也有了提高。在这次设计过程中，体现出自己单独设计plc的能力以及综合运用知识的能力，体会了学以致用、突出自己劳动成果的喜悦心情，从中发现自己平时学习的不足和薄弱环节，从而加以弥补。在此感谢我们的plc老师。老师严谨细致、一丝不苟的作风一直是我工作、学习中的榜样；老师循循善诱的教导和不拘一格的思路给予我无尽的启迪；这次设计的每个实验细节，都离不开老师您的细心指导。而您开朗的个性和宽容的态度，帮助我能够很顺利的完成了这次课程设计。同时感谢对我帮助过的同学们，谢谢你们对我的帮助

9、和支持，让我感受到同学的友谊。 由于本人的设计能力有限，在设计过程中难免出现错误，恳请老师们多多指教,我十分乐意接受你们的批评与指正，本人将万分感谢。李杰：通过这次对彩灯循环点亮的PLC控制，让我了解了plc梯形图、指令表、外部接线图有了更好的了解，也让我了解了关于PLC设计原理。有很多设计理念来源于实际，从中找出最适合的设计方法。 本次课程设计脱离不了集体的力量，遇到问题和同学互相讨论交流。多和同学讨论。我们在做课程设计的过程中要不停的讨论问题，这样，我们可以尽可能的统一思想，这样就不会使自己在做的过程中没有方向，并且这样也是为了方便最后设计和在一起。讨论不仅是一些思想的问题，还可以深入的讨

10、论一些技术上的问题，这样可以使自己的处理问题要快一些，少走弯路。多改变自己设计的方法，在设计的过程中最好要不停的改善自己解决问题的方法，这样可以方便自己解决问题 现在整个设计基本完成，过程中出现了一些问题，例如延迟不是蛮准确，电路设计的不是蛮完善。我想只有我们在实践中多总结，多思考，才能真正地做到学以致用！才能达到学习的真正目的！Employment tribunals sort out disagreements between employers and employees.

28、自己的怯懦，最终却发现有很多缘分，有很多错过，好像冥冥之中真的已经注定。那些曾经所谓的非做不可，只是青葱年华里自己给自己注射的一支强心剂，或者说，是自以为是的精神寄托罢了。At the moment, the sky is dark, the air is fresh factor after just rained.
