摘 要
随着社会的进步、科技日新月异，18世纪60年代工业革命时期生产线主要以蒸汽机为动力，到现在已经发展成了全自动化大批量生产。可以说现代工业已经离不开自动化的生产线了，自动化生产线不仅可以大幅度地提高生产效率，而且还可以提高精度、提高合格率、减轻人的工作量等好处。传统的单片机等电器控制技术有很多功能无法实现，在工业如此发达的今天，生产线控制系统逐渐地被PLC控制代替。
针对我国一些小型企业的配料生产线控制系统现状，本文将Siemens S7-200系列的PLC应用于小型的配料生产线，再由组态王制作人机交互的界面，作为监控系统实现实时监控功能。运用与S7-200系列PLC相配的STEP7编程，从而使该配料系统可以按要求完成自动配料，装料全过程。
本文的主要内容包括对生产过程控制系统发展和现状的概述、配料系统工作原理和配料控制系统的总体设计，重点描述了包括硬件设计、软件编程设计在内的S7-200 PLC在配料系统中的详细步骤、组态王监控系统中一些基本设计，以及PLC与组态王之间的通讯。本设计通过合理的选择和编程，提高了配料生产线的生产效率，降低了成本，并且提高了系统安全可靠性。

ABSTRACT
With the progress of society and the great changes of science and technology, from the 1760s when the steam engine is acted as the main power of the beginning of the industrial revolution to now, industrial production lines have experienced 300-year developmental history, and has developed into fully automated mass production currently. It can be said that modern industry has been inseparable from the automated production line. Automatic production line not only can greatly improve the production efficiency, but also can improve the precision, boost qualified rate, reduce the workload. Nowadays industry is developed, and production line control system is r gradually replaced the original single chip computer or electrical machinery control with the PLC control. Many of its functions can not be achieved just through traditional control technology .
This paper aims to small business ingredient production line control system in our country, and applys the PLC of Siemens S7-200 series to small batch production line, and treats kingview as a human-computer interaction interface for monitoring function. First, the Siemens PLC S7-200 is used to control automatic proportion system. The proportioning system included the requirements of automatic proportioning, weighing, and loading. Next the Kingview software is used to build the real-time supervisory system. The system can realize the real-time data-logging, as well as various visual.
Paper’s contents mainly include that the industrial control system development and present situation outline. The ingredient system principle of work and the ingredient control system's design, described with emphasis including the hardware design, the programming environment and software design Siemens PLC in ingredient system's application some details, the configuration software configuration king and in the host computer supervisory system some basic designs, as well as communication between PLC and host computer. This paper through the reasonable selection and programming, improve the batching production efficiency, reduce the cost, improve the safety and reliability, and make reasonable adjustment of PLC program parameters according to the different ingredients .
