基于单片机的温湿度检测与控制系统研究

Research On The Measure And Control System Of The Temperature And Humidity Based On Single Chip Microcomputer

单片机在检测和控制系统中得到广泛的应用,温、湿度则是系统常需要测量、控制和保持的量。文中介绍了一种基于ATA9C51的单片机的温度和湿度检测与控制的方案,针对被测对象的温度与湿度在不同变化范围需要不同的PID参数的特点,根据检测温度和湿度自动选择合适的一组PID参数进行控制的方案,整个设计简明、清晰。

The singlechip microcomputer is required extensively in measurement and control systems and the temperature and humidity need to be surveyed, controlled and maintained by a system frequently. The schemes of the measure and control of the temperature and humidity based on single chip microcomputer AT89C51 is introduced in this paper. In view of the characteristics of the different PID parameters with the different temperature and humidity, selects appropriate PID parameters to control on the basis of the measured temperature and humidity, and the whole design is very clear and concise.
