基于太阳能热水器智能控制器设计

摘要

Combined with the application of solar water-heaters,an intelligent controller based on fuzzy algorithm is de-signed,which takes the STC89C52RC MCU as the controller,and uses DS18B20 digital temperature sensor for temperature mea-surement. The zero-trigger solid-state relay is used for controlling the heating rod to simulate the auxiliary heating of solar water-heaters. The controller can intelligently adjust the output power during the heating process,so that the temperature will reach the set point in the set time.%结合太阳能热水器的具体应用，设计了基于单片机的模糊智能控制器。系统采用STC89C52RC单片机，利用DS18B20数字温度传感器进行温度测量，通过过零固态继电器控制加热棒以模拟太阳能热水器的辅助加热功能。实现在设定的时间内智能调整输出功率，使水温在设定时间内达到设定值。
