毕业设计（论文）报告 题 目:基于PLC的自动药片装瓶控制 摘 要 PLC可编程序控制器其实质是一种专用于工业控制的计算机，其硬件结构基本上与微型计算机相同采用一类可编程的，用于其内部存储程序，执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。PLC programmable controller and its essence is a kind of special for industrial control computer, and its hardware structure is basically the same with micro computer. It adopts a kind of programmable memory, for its internal storage procedures, the implementation of logical, sequential control, timing, counting and arithmetic operations such as user-oriented instructions, and through digital or analog input / output control various types of machinery or production process. In todays pharmaceutical industry, automatic bottling machine has been widely used, it from the PLC through the USS communication protocol to control the motor directly. Not only can realize the charging machine operation control, and can flexibly control the charge time, save energy, reduce costs, improve production efficiency and other purposes. PLC special I / O indication function and simple PLC control hard wiring that find the point of failure is very rapid, convenient. PLC host work reliability, failure rate is very low. Therefore, this paper uses PLC to design a bottling machine control system.
