多功能超临界流体萃取分馏仪监控系统的设计与实现

Instrument of Supercritical Fluid Extraction and Fractionation Supervise System

给出了多功能超临界流体萃取分馏仪监控系统的硬件设计方案和VB6.0环境下软件编程实现。系统采用复合滤波与积分分离PID相结合的数据处理算法,实现了对监控系统中温度和压力的实时控制、动态显示和数据打印。

This paper present the hardware design of multi-function instrument of supercritical fluid extraction and fractionation supervise system,and then program with VB 6.0 to realize it.This system use the data processing arithmetic：combine compound-filter and PID, realize the real-time control,dynamic curve display and data print.
