密炼机智能控制上位机系统的软件设计

Up stage Computer System Programming for Intellective Mixing Process Control

论述了密炼机智能控制上位机系统的软件设计思路，介绍了上位机系统的常用功能模块。该系统是在Ｗｉｎｄｏｗｓ ＮＴ４ ．０ 的环境下，用Ｄｅｌｐｈｉ３．０ 语言开发的。系统实现了实时监控多台下位机系统的工作状态，并具有远程控制功能；同时可向下位机系统采集历史数据，还可对历史曲线图进行多种类型的查询和打印。

The programming idea of up stage computer system for intellective mixing process control was introduced and the common functional modules were described.The system was developed by using Delphi 3.0 Language in Windows NT 4.0 environment.The system could be used to a) monitor the working conditions of multi down stage computer system in real time;b) realize the remote control;c) gather the historical data from the down stage computer system;and d) inquire and print the historical curves in many ways.
