基于PIC单片机的中央空调智能温度控制器设计

Design of Intelligent Temperature Controller of Centralized Air Conditioner Based on PIC Microchip

针对智能楼宇集中供热、制冷的要求,提出了中央空调房间温度控制方案。介绍了一种基于PIC单片机、DS18B20数字温度传感器及一些外围电路组成的中央空调智能温度控制器。针对被控对象的大时滞、非线性等特点,系统采用模糊免疫PID算法对温度进行控制,可使系统具有良好的控制性能。

Aiming at the requirement of heat and cooling control in intelligent building,a plan of the temperature control of the central air-conditioner room was proposed.A intelligent temperature controller of centralized air conditioner design based on PIC and digital temperature sensor DS18B20 and some outer circuits were introduced.Because the model of system had the characteristics of time lag and nonlinear,fuzzy PID based on immune feedback control algorithm was adopted to control the temperature.The system acc...
