我厂各主要生产装置的实时过程数据由四套DCS系统采集和设定。生产调度监测系统服务器（以下称上位机）采集DCS系统的各种数据，并把采集到的数据实时存入生产调度服务器数据库系统中，自动地形成历史数据库。其它与上位机通过网络连在一起的计算机可以通过计算机网络能够快速并准确无误地取得实时数据和历史数据。

三、数据采集软件的核心算法
鹰化厂生产调度监测系统数据采集软件运行于上位机上，软件用VB5.0企业版开发，由于数据采集软件的主要功能是采集DCS系统的实时过程数据，因此，其核心算法便是对RS232C TTY通信口进行有效的控制的方法，这方面的主要算法有以下几个：（由于篇幅所限，在此只列出主要核心算法的代码）
3-1多个RS232C TTY 串口通信是同时进行的
由于VB不支持多线程开发，因此只利用VB的内部功能无法做到多串口通信同时进行。利用VB的定时器控件数组巧妙地实现了多个串口同时通信而不互相干扰，这样大大加快了通信速度。
以下代码实现从数据库中取出各种通信参数动态生成多个通信控件MM、
