智慧化控制羔羊保温箱应用效果评价OA

To meet the requirements for lamb conservation in the cold northern regions in China,this study designed an intelligently-controlled lamb incubator.An experimental assessment of lamb conserva-tion was conducted using this incubator,with the internal microclimate environment monitored and ana-lyzed.Additionally,a fisheye panoramic network camera was employed for lamb surveillance and invento-ry,to evaluate the functionality of the lamb incubator and to develop context-appropriate intelligent con-trol strategies.The results showed:(1)The incubator,applied within a sheep shed maintained at an aver-age temperature of-2℃,demonstrated excellent heating performance,maintaining a stable internal tem-perature within the target range of 8～10℃.The Temperature-Humidity Index(THI)ranged from 50.91 to 51.44,placing the lambs within the comfort zone,thereby addressing cold stress issues.(2)Lambs in the experimental group using the incubator exhibited superior growth performance,with the average daily weight gain significantly higher(P＜0.05)than that of the control group.Additionally,the feed-to-gain ratio was significantly lower(P＜0.05).(3)The utilization rate of the incubator was relatively high.Lambs could adaptively enter the device without the need for learning or manual intervention.On average,seven lambs entered daily,with a maximum of twelve,and their free access did not adversely affect nurs-ing behavior.(4)The suggested operating duration for the heating lamp was significantly negatively corre-lated with ambient temperature.The average daily operation time was 21.5 hours.Based on the 250 W heating lamp used in this experiment,the average daily power consumption was 5.375 kW·h,correspond-ing to a daily electricity cost of approximately 2.95 yuan.These results demonstrate that the intelligently-controlled lamb incubator possesses significant practical and economic value.
