plc四级传送带控制系统设计

摘要

传送带系统最大特点是它的综合性和系统性，综合性主要涉及机械技术、微电子技术、电工电子技术、传感测试技术、接口技术、信息变换技术、网络通信技术等多种技术有机地结合，并综合应用到生产设备中；而系统性指的是生产线的传感检测、传输与处理、控制、执行与驱动等机构在微处理单元的控制下协调有序地工作，有机地融合在一起。本系统完成一个基于plc的四级传送带的设计。系统的控制方式采用每一工作单元由一台PLC承担其控制任务，各PLC之间通过实现互连的分布式控制方式。所以，本设计综合应用了多种技术知识，如传感器应用技术、PLC控制和组网、步进电机位置控制和变频器技术等。

Abstract

The biggest characteristic of the automatic production line is a comprehensive system and its comprehensive, mainly involved in mechanical technology, microelectronics technology, electrical and electronic technology, sensing technology, interface technology and information transformation technology, network communication technology and other technology organically, and applied to production equipment and systems; means the production line of the sensor detection, transmission and processing, control, execution and driving mechanism in the control of the micro processing unit under the coordination and orderly work together organically. The system completes the design of an automatic heating line for the production of automobile carpet. The control mode of the system is that each working unit is controlled by a PLC, and each PLC is connected by RS485 serial communication. Therefore, the design of the application of a variety of technical knowledge, such as sensor application technology, PLC control and networking, stepper motor position control and inverter technology, etc..

Key words: network configuration automation PLC motor
