干燥装置工作参数自动调控系统的设计

Design of a Parameter-Monitoring and Logging System

【摘要】采用可视化编程语言VB6.0中串行通信控件来实现计算机对监控热泵干燥系统的干燥室空气温度、相对湿度、流速以及制冷系统中蒸发压力、冷凝压力等工作参数进行自动采集,并触发越限报警,降低了干燥过程中人工反复读数记录的操作强度,提高了控制精度。

This paper uses serial communication active control provided by Visual Basic 6.0 to log and monitor parameters of drying temperature, air humidity and velocity, the evaporation pressure and condensation pressure of the refrigerant automatically by a computer, reducing the intensity of operation, increasing the control precision on working conditions and improving the performance of the heat pump drying system.
