Automation technology is to explore and research process automation of the methods and technology. It is related to the mechanical, microelectronics and computer technology in the field of a comprehensive technology. The industrial revolution is the automation technology of the midwife. It is because of the needs of the industrial revolution, automation technology just broke through the egg shell, obtained the vigorous development. At the same time automation technology also promoted the progress of industry, now automation technology has been widely used in mechanical manufacturing, power, construction, transportation, information technology and other fields, and become the main means to improve labor productivity. On the social form, I design based on Siemens PLC touch screen with transportation control system. This design can satisfy simple conveyor belt control, simple operation, easy to understand and friendly interface. Can achieve manually rev. Stop, stop, and automatic and alarm system. Keywords: automatic control, the conveyor belt, PLC 第一章 引言 1.1运输带在生产中的应用 运输带输送是基于PLC的自动控制系统，它在水泥、煤炭、冶金、化工、饲料、食品等行业有很广泛的应用。具有功能全面，灵活性强，性价比高等特点，受
