Abstract: In order to solve the problem that the traditional heating device can not meet the somatosensory temperature requirements of piglets of different days of age and high energy consumption, the intelligent heat preservation control system for piglets in the delivery house was designed. According to the environmental factors such as temperature, relative humidity and wind speed in the piggery, the intelligent insulation control system was designed for piglets to calculate the appropriate range of somatosensory temperature and adjust the output power of the insulation equipment intellectively and in cluster to meet the demand of somatosensory temperature for piglets of different stages and days of age. The experiment of the piglet insulation control system in the delivery mother pig house was carried out, the experimental results indicated that the system could control the somatosensory temperature of piglets within the set temperature range, and the somatosensory temperature fluctuation range was within ±0.75℃. The coefficient of variation calculated from the somatosensory temperature data at different ages was less than 0.1, which showed weak variability, indicating that the dispersion degree of somatosensory temperature was small, and the effect of systematic control of somatosensory temperature was relatively stable. This study can provide reference for the environmental regulation of delivery sows.

摘要： 为解决传统仔猪加热装置难以满足不同日龄仔猪体感温度需求、能耗高等问题，设计一种分娩舍仔猪智能保温控制系统。分娩舍仔猪智能保温控制系统根据猪舍养殖环境因子如温度、相对湿度和风速，推算仔猪当前的体感温度，智能和集群调节保温设备的输出功率，以满足不同阶段日龄仔猪对体感温度的需求。开展分娩母猪舍仔猪保温控制系统试验，试验结果表明，该系统能够将仔猪体感温度控制在设定温度区间内，体感温度波动范围在±0.75℃内。不同日龄下体感温度数据计算出的变异系数均小于0.1，表现为弱变异性，说明体感温度的离散程度较小，系统控制体感温度效果相对稳定。该研究为分娩母猪舍环境调控提供参考。
