摘要

PLC技术，控制起来非常简便，并且它能够承受高温及其他的恶劣的环境条件，所以plc比起单片机来，工业上优先使用plc，它已经成为了当代工业流水线和企业最受欢迎的自动化控制方法。

PLC技术融合了传统的继电控制技术，现代的计算机技术，以及发达的通信技术，专门为了工业应用和工厂设备而设计。并且具有：使用方便，编程简单，功能强，性价比高，可靠性强，抗干扰能力强，适应性强，后期处理、维修简单方便等诸多优点，比起单片机来更加可靠与实用，这就是人们选择plc的“内”因。再加上plc小巧的外形包装，超低的重量，和超小的功耗这些“外”因，使得plc越来越受工业企业的推崇与喜爱。

本文论述物料自动分拣系统，主要应用PLC技术，辅助以启动装置，位置技术，现场总线技术，电机拖动原理，电气传动技术，传感技术，自动检测技术等设计而成，对大批的物料进行自动分拣的工作，完成分门别类的放置物料。本系统具有很多的优点，例如，运行起来比较稳定，精度与敏捷度，自动化的程度都很高，而且非常便于使用和控制，如果你想使用它来分装另一批货物的话，只需要动动手指，对本系统稍加修改，对本程序稍作处理即可。

ABSTRACT

PLC technology, control is very simple, and it can withstand high temperatures and other harsh environmental conditions, so PLC than SCM, industry give priority to the use of PLC, it has become the automatic control method of the most popular contemporary and industrial assembly enterprises.

PLC technology combines the traditional relay control technology, modern computer technology and communication technology developed, specifically for industrial applications and factory equipment and design. And has the merits of easy use, simple programming, strong function, high price, high reliability, strong anti-jamming ability, strong adaptability, post processing, maintenance is simple and convenient, compared with the single chip microcomputer to more reliable and practical, this is what people choose PLC "in". Plus PLC compact appearance package, low weight, and small power consumption for these "outside", makes the PLC more and more respected and loved in industrial enterprises.

In this paper, automatic material sorting system, the main application of PLC technology, aided by starting device, location technology, field bus technology, driving principle of the motor, the electric transmission technology, sensor technology, automatic detection technology and design, for a large number of material for automatic sorting, complete categories of placing the material. The system has many advantages, for example, up and running stability, precision and agility, high degree of automation, and very easy to use and control, if you want to use it to packaging another batch of goods, only need to fingertips, of the system slightly Acacius change of the programs are slightly can handle.

Key words: PLC; programmable logic controller; sorting device system; control system; induction system
