摘要
本文论述了利用MSWindows及VisualBasic（以下简称VB）forMSWin－dows的消息处理、图形处理等功能，直接开发中型规模的以员工仿真操作培训为目的、以工业集散控制系统（DCS）为仿真目标的应用系统．所开发的仿真软件对于一套3万吨／年的装置上的Foxbouo／k司的I／A控制系统的操作员环境的主要常用功能进行了逼真的模拟．
In this paper,the developing of a middle scale simulation sofruare was describde,whichis designed for training operators and has the purpose of sinulation a industry distirbutivecontrol system(DCS). Microsoft windows and Visual Basic are the tool softwares we used,whic have some stronge functions: message processing, graph processing, automatic mousesupporting and so on. The simnlantion software has simulated the operation envivoment ofFoxboro's I/A system, which controled the methanol equipment in Dushanzi,with productionof 30000 tons a year.
