一个基于OMRONPLC冰箱老化测试生产线控制系统.docVIP

摘 要 本课题设计一个基于 OMRON PLC的冰箱老化测试生产线的控制系统，主要控制箱体在多条生产线中的进出功能，确保安全、畅通地按照既定工艺进行箱体传送，以实现地面输送线的自动控制。本设计采用OMRON C200H型PLC及西门子变频器作为主要的控制器件，来完成的自动移及。详细介绍了PLC控制。软件是利用型PLC的基本指令和特殊功能指令构建控制程序的，包括梯形图、程序指令表和时序图。 Abstract The aging test subject to design a refrigerator production line control system programming based on OMRON PLC.The design of the main control box in a multi-production lines in and out of function, to ensure safe, smooth box according to the established technology of transmission lines in order to achieve automatic control of ground transportation. This design uses OMRON C200H PLC and Siemens inverter type as the main control device, to complete the transmission line refrigerator automatically shift the ground set and different modes of production control. This paper describes the ground conveyor system PLC control and programming. Software-based PLC using CX-P basic instructions and special function instruction building control procedures, including the ladder, the program instruction table and timing diagram. Through the process of preparation.Achieved the purpose of automation and increased crash protection design. Since the programs versatility, it can be used by small changes to other production lines. Ground transportation system for refrigerator design, this comprehensive comparison of the various programs that use this system, the design of many advantages.According to this design of the refrigerator conveyor line automatic control system,this system has strong function, low cost, easy maintenance,and high reliability .Which has great practical significance. Key words： The ground conveyor system, programmable logic controller,frequency converter,Photoelectric switch 目录 摘要 I Abstract II 第一章 引言 错误！未定义书签。 1.1本课题研究的目的和意义 1 1.2 地面输送线控制系统国内外发展现状 1 1.3本课题的任务 3 1.4本课题的设计方案 3 第二章 地面输送线的总体设计方案 4 2.1地面控制线的功能需求分析 4 2.2 系统设计的基本步骤 4 2.3 系统的基本要求 5 第三章 硬件电路的设计 6 3.1 plc的概述及选型 6 3.2.变频器的原理及选型 6 3.3光电传感器的原理及选型 7 第四章 控制系统的设计 11 4.1 系统的基本设计思路 11 4.2 控制系统组成元件分析 12 4.3 电
