摘 要 ABSTRACT For the rapid development of era and anxious request of people’s improving their living quantity people have thought much of production’s packing than before. This makes packing industry to develop fast. In our country, the study of monitoring and control packing line is little though signal machine in the line has controlled well. The queston that the line is not automatized and intelligentized exists. In order to be seasoned with the development of present-day packing industry and improve the degree of packing product line automatization and intelligentize, I have processed a study of packing product line distributed monitoring and control and diagnosis system in this text . According to the system’s common design principle,I have exploited this system independently. The main work in this text: 1. The design of equipment’s controlling hardware: including selecting models of controlling apparatus and theirs building configuration and connecting them; 2. The design of system software: I have exploited software of communication and monitoring and control using Visual Basic 6.0 . I have realized my anticipated aims on the whole; 3. using fuzzy fault diagnosis method in the line: I have diagnosticated packing machine that is the key equipment in the line. Keywords: distributed monitoring and control and diagnosis system， serial communication,plc,singalchip,fuzzy fault diagnosis 目 录 第1章 4 1.1 研究的内容和目的 1.2 国内外现状及发展趋势 1.3 研究的价值和意义 1.4 研究方法措施 1.5 本文结构 第2章 包装生产线分布式监控、诊断系统总体设计 2.1 分布式控制系统的结构及特点 2.2 分布式系统中常用的控制装置 2.2.1 可编程控制器（PLC） 2.2.2 单片微型机 2.2.3 工业PC-IPC 2.3 包装生产线分布式控制系统的总体设计 2.3.1 系统硬件构成 第3章 包装生产线分布式监控、诊断系统硬件设计 14 3.1 系统所用的PLC 14 3.1.1 PLC的通信模块 3.1.2 FX2N-48MT型号PLC 3.2 系统所用的单片机 3.3 RS-232C和RS-485总线标准 3.4 转换模块及与中央IPC的RS-232串行通讯接口的连接 17 3.5 包装生产线系统各生产设备及其控制简介 3.5.1 提升机PLC控制子系统简介 3.5.2 充填机单片机控制子系统简介 19 3.6 包装机PLC控制子系统简介 3.7 运输、选别机单片机控制子系统简介 毕业论文开题报告 学生姓名：杨秀清 学号： 专业：机电一体化 指导教师：佘勃 2008年04月01日 1.1 研究的内容和目的 本文
