AT80C52单片机温差控制系统在太阳能辅助热源密集烤烟房上的应用

Temperature Control in Solar Thermal Collector Installed in Solar Energy Auxiliary Heat Source Bulk Curing Barn Based on AT80C52

该温差控制系统以AT80C52单片机为控制单元,利用DS18B20温度传感器监测太阳能辅助热源密集烤烟房的集热器内温度和装烟室内温度,并通过比较两者之间的温度实现当集热器内的温度比装烟室的温度高15℃时,风机工作、电动风阀打开,集热器向装烟室供热;当两者之间的温差下降到小于8℃时,风机停止工作、电动风阀关闭。

With AT80C52 microcontroller as the control unit,the use of DS18B20 sensor to monitor the temperature inside the solar thermal collector and curing barn,and through the comparison of them,when the temperature inside the collector is 15 ℃ higher than the curing barn,the fan and blast gate begin to work; when the temperature difference drop below 8 ℃,the fan and blast gate shut up.
