哺乳期仔猪局部温度智能控制系统设计

Design and Experiment of Intelligent Control System for Local Temperature of Suckling Piglets

针对目前仔猪小环境加热装置无法满足仔猪生理需求、温度可控性差、能耗高等特点,设计开发一种规模化养猪场仔猪小环境智能加热保温系统,能够预设哺乳仔猪生长各阶段适宜温度范围,结合仔猪日龄实现自动精准控温,满足仔猪生长对温度的需求,降低耗电量,节约生产成本。智能加热装置在黑龙江省阿城区滨圣种猪养殖场仔猪舍进行冬季和夏季两个阶段测试,试验结果表明:在冬季,温度可以控制在仔猪生长所需的适宜范围内;在夏季,当舍内温度处于或高于仔猪生长适宜温度时,智能加热灯泡无需开启,与传统的非智能控制方式相比,降低了能耗。通过计算,在测试的冬季和夏季两个阶段,该智能加热装置电能消耗分别是使用灯泡持续加热的63.60%和39.35%,节省电能效果明显。

Current heating system for local temperature of suckling piglets can not meet the physiological needs of piglets,which has poor temperature controllability and high energy consumption.An intelligent control system for local temperature of suckling piglets in large-scale pig farms was designed and developed,which could preset the comfortable temperature range for each stage of piglet growth,and realize automatic and precise temperature control according to piglet's day age to meet piglet's growth demand.The experiments of intelligent control system were conducted in Binsheng Breeding Piggery Farm in Acheng City of Heilongjiang Province during winter and summer.The results showed that in winter,temperature can be controlled within the comfortable temperature range for piglet growth.In summer,when the indoor temperature was below or above the comfortable suitable temperature range,the heating bulbs were turned off.It reduced more power consumption than the continuous heating system.Through calculation,the energy consumption was 63.60%and 39.35%of that of continuous heating system in winter and summer respectively,with a significant energy saving efficiency.
