中文摘要：

熔滴喷射装置内的温度、气体压力及激振频率直接影响熔滴喷射质量。以LabVIEW为开发平台开发的熔滴喷射的关键参数测控系统,通过RS—232串口实现了计算机与传统仪器的信息传送。以DAQ卡PCL—818L为基础,完成了对过程变量的检测,并通过改进实际PID控制器和利用LabVIEW内嵌的PID控制工具包,实现了对温度的精确控制。

英文摘要：

In the process of molten droplet ejection,the quality of the droplets is affected by some key parameters,such as temperature,gas pressure,actuator frequency.A measurement and control system for molten droplet ejection has been developed based on LabVIEW.This system communicates with traditional instrument through RS—232 serial port,measures process variable using PCL—818L.By improving actual PID controller,this system realizes temperature precise control in virtue of PID control toolkit in LabVIEW.
