摘要
在洁净手术室的温湿度控制系统中,温湿度控制是一种非线性、大滞后、时变的复杂过程。本文介绍了以S7-200PLC为主控制器,实现在不同工况下温湿度的PID控制。运行结果表明,该温湿度控制系统具有较高的抗干扰能力,可靠性高,运行稳定,温湿度控制精确,完全能满足洁净手术室应用要求。
In the humidity temperature-conditioning system for the ultra-clean operation-room,the humidity and temperature conditioning process is non-linear,time-lagging and complicated.This paper mainly focuses on the S7-200PLC system and intends to clarify the PID humidity and temperature conditioning in various circumstances.And according to the findings of the trial operation,the system can fully satisfy the needs in the ultra-clean operation-room for its superior interference-proof function,good reliability in operation and accuracy in the humidity and temperature conditioning process.
