摘要
介绍了一种基于单片机AT89C52和DS18B20数字式温度传感器的哺乳仔猪舍温度、湿度自动控制系统,阐述了系统的硬件结构、工作原理及过程,并对系统的控制效果做了大量的试验,结果表明该系统能满足随仔猪出生天数增加而自动调低所控制温度的要求。该系统的使用,对降低仔猪发病率、打堆次数和频率,增加仔猪的睡眠时间,提高仔猪成活率和仔猪的日增重有明显效果。
In this paper, the author introduces a sort of autocontrol system of the temperature and humidity in the sucking piglet house based on the single-chip microcomputer AT89C52 and the digital thermo-sensor DS18B20. Mainly about the hardware structure, the operating principle and process. The author has clone a lot of experiments about the control effect. The result indicates that it can fulfill the demand of adjusting the temperature automatically along with the increase of the days of the piglet birth. The usage of this system can take effect on reducing the incidence of a disease and the time and frequency of conglomeration, increasing the sleeping time, heightening the survive ratio and weight increase by days.
