基于沉降仪的摄像升降平台的PLC控制设计(任务书,开题报告,论文说明书13000字)
摘要
21世纪，粉体产业已经成为人们非常受重视的基础产业之一，粉体在我们的日常生活和工农业生产制造中的应用变得越来越广泛，如面粉、塑料、水泥、造纸、陶瓷、橡胶、药品等等，粉体的粒度测试是粉体制造和研究的重要辅佐手段。我国在仪器测试的研发以及使用方面已经做出了非常多的工作项目，这为这项技术的进一步起飞成长奠定了很大的基垫。因为我国的绝大多数科技职员具有很高的技术基础素质和费用比较低的人工花费，在现在的国际大市场的背景下，我国非常具有能力成为测量仪器制造大国乃至成为这一领域内的顶尖技术国，而沉降仪是目前我国有能力自行制造的非常重要的粒度测试仪之一。
本文主要研究的问题是基于沉降仪的摄像升降平台的PLC控制设计，是以我校（武汉理工大学）开发沉降仪项目为背景，为沉降仪项目而设计。其目的为根据沉降仪的摄像升降平台需求，设计其相关PLC控制程序。根据沉降仪的沉降分级模式的工艺流程，设计以S7-200为主要控制结构与硬件电路，编写并调试PLC程序，完成沉降仪摄像云台启动初始化，实现摄像云台升降控制功能以及点动控制功能。

Abstract
Fully equipped with the background of now is in the 21st century, powder industry has become one of the most important basic industry of powder in our daily life and industrial and agricultural production is applied more and more widely, such as flour, plastic, cement, paper, ceramics, rubber, medicine and so on, powder particle size measurement of powder production and research is an important auxiliary means. In our country in the test instrument of research and development and application has been made very much work, which is the technology further takeoff development laid a great foundation. Because of China's scientific and technical personnel with good technical quality and relatively low labor costs, in the international market, China's ability to The settlement instrument is one of the important modern particle size instrument which is capable of producing the instrument.
In this paper, we mainly study the problem is settlement gauge camera lifting platform of PLC control system design based on, is in my school (Wuhan University of Technology) development settlement instrument project as the background, designed for settlement instrument project. Its purpose is according to the settlement gauge of photograph elevating platform requirements, design the PLC control program. According to the settlement settlement instrument of classification model for the process design to S7-200 as the main control structure and hardware circuit, write and debug PLC program, completion settlement gauge PTZ camera initialization, PTZ camera lifting control function and control function.
Key words:Particle size measurement; sedimentation instrument; S7-200; step motor
