文档介绍:基于 PROFIBUS 现场总线的 PLC 自动装配系统研制中文摘要
中文摘要
PROFIBUS 是一种用于工厂自动化车间级监控和现场设备层数据通信与控制
的过程现场总线。它可实现现场设备层到车间级监控的分散式数字控制和现场
通信,从而为工厂综合自动化和现场设备智能化提供了可行的解决方案。
本文主要开发和设计了一套基于 PROFIBUS 现场总线的 PLC 自动装配系统。自动
装配系统由送料站、检测装配站、伺服仓储站等三个工作站组成。第一站实现自动送
料;第二站实现产品颜色判断和自动装配;第三站实现伺服定位仓储(将合格品送入
规定的仓储站)。三站均设置 S7-300 系列 PLC 作为控制系统和数据采集,采用
PROFIBUS—DP 现场总线实现自动装配系统主站和从站的联网通讯,同时采用人机界
面(触摸屏)实现实时监控和故障报警显示。
本论文主要完成以下内容:
1、自动装配系统总体方案、总体架构及工作站功能流程图设计;
2、各工作站电气动回路设计以及基于 Fluid_SIM 软件的运动仿真分析;
3、各工作站 PLC 控制系统原理图设计
4、西门子 PLC 的选型、PLC 硬件组态与软件系统;
5、PROFIBUS 概述以及 PROFIBUS-DP 硬件网络组态;
6、自动装配系统控制程序设计;
7、自动装配系统监控界面设计与开发。
关键词:PROFIBUS-DP、现场总线、自动装配系统、主站、从站、人机界面

Abstract
PROFIBUS is a Field bus which is most extensively used in workshop of factory
automatic control. It can realize digital control and work between
field equipment and supervisory workshop. Consequently, it provides an available solution
to realizing factory integrated automation and intelligent field devices.
This dissertation has mainly developed and designed an Automatic Assembly System
which is based on PROFIBUS Field bus and PLC. Functions of this system: First station:
feeding automatically. Second station: color identification and automatic assembly. Third
station: servo-positioning storage. (put qualified products into storage station.
Automatic Assembly System posed of feeding station, detecting of assembly
station and servo-storing station. Each station is set up S7-300 PLC as its data acquisition
and control system. It realizes munication between master station and
slave station through PROFIBUS-DP Field bus. At the same time, human machine
interface(HMI) is used to monitor and display the malfunction of the process.
What have been plished through the project are as follows:
1、The scheme design of Automatic Assembly System, the design of overall framework and
function of stations.
2、The design of the pneumatic circuit of each station, and
