ITO导电玻璃连续式生产线的计算机监控系统设计
摘要
随着信息技术的快速发展，液晶显示器件(LCD)由于它具有低功耗、IC驱动、重量轻、外形薄、辐射小及长寿命等优点已广泛地用于便携式笔记本电脑、移动电话PC机的监视器及彩电、儿童玩具等消费类产品。LCD已成为显示器市场最为活跃很有发展前途的现实产品，并正在替代CRT(阴极射线管)，成为21世纪初的主流显示设备。
ITO(Indium tin Oxide)镀膜透明导电玻璃是生产液晶显示器件的关键基础材料之一，它是山镀膜生产线在玻璃上面均匀的镀上一层ITO膜而成。因此，要求导电玻璃生产线能够稳定、可靠的连续工作。
本文主要解决ITO透明导电玻璃连续生产线自动控制方面的问题，以确保生产线能够稳定、可靠、连续的工作，具体包括四部分：①下位机控制子系统。实现生产现场数据采集，分析并对其进行实时控制。同时，将现场状态通过RS-232接口发送给上位监控计算机，并接受监控计算机的命令。②串行通信子系统。它由下位机的上位链接模块和上位机的串行通信模块组成。在上位机和下位机之间完成数据的发送和接收。③上位机人机交互界面。上位机控制用于实现人机交互作用。该部分完成3件事：接收用户对下位机的设定数据；显示下位机的工作状态和作为监控网络的服务器端。④监控网络。实现生产现场、工厂管理者和设备提供方三方共同对尘产线进行监控。生产现场与工厂管理者间通信采用TCP/IP(Transmission ControlProtocal/Internet Protocal)传送控制协议/网络层协议的面向连接的套接字(Socket)技术实现；与设备提供者之间通信采用利用Telephony API(Application Program Interface)的利用SMTP(Simple Mail Transfer Protocal)简单邮件传输协议实现发送电子邮件。
As the rapid development of Information Technology. As a low power, IC
driving, light weight. low-radiation, durable, and reliable display, LCD(Liquid Crystal
Display) is being used widely for Laptop Computer, mobile-phone, computer display,
Color TV set and children's toys. LCD is becoming the most promising display
product. Also, it is taking the place of CRT (Cathode Ray Tube), and will be the chief
display device in the early days of 21st century.
The transparent and conductive glass with indium tin oxide (ITO) films is the
fundamental part of LCD. It has been proved that high-quality ITO films for Industrial
use could only be produced in automatic production lines.
The continuous production line for producing transparent and conductive glass is
an enormous system; it deals with lots of technologies such as mechanics, electronics,
vacuum science and film technology.
This paper will mainly concentrate on solving the controlling network for this
continuous, automated production line; and it will ensure the steady, reliable and
continuous work of the production line. This controlling network can be described as
four parts:
First, the PLC (Programmable Logic Controller) real-time controlling system. With
the data set up by computer, it collects, analyzes the signals from production line and
controls it's working directly. It was realized with LSS provided by OMRON.
Second, the serial communicating system. It is made up of two parts: Communicating
module of PLC and the communicating program of supervision interface. This system
accomplishes the work of sending and receiving data between PLD and PC (Personal
Computer). it was realized with the serial port programming theory of C++ Builder.
Third, the supervision interface of the controlling computer. This part accomplishes
three works: Accepting the setting for PLC from user; displaying the working state of
the production line and working as the Server for the supervision network. It was
realized by C++ Builder.
Fourth, the supervision network. This network composed of the computer operated by
workers (Server), the computer operated by managers of the factory (Client) and the
computer of the device provider (Third Part). The network between Server and Client
is called the remote local access network (RLAN); the network between Server and
the Third Part is called remote fault checking network (RFCN). This supervision
network was realized with the mechanism of TCP/IP (Transmission Control
Protocol/Internet Protocol) and the SMTP (Simply Mail Transfer Protocol) of
Telephony API (Application Program Interface).
