【摘要】：為建立母豬健康模型和分析母豬分娩、發(fā)情等過程體溫變化規(guī)律提供數(shù)據(jù)支撐,研制了一種基于MLX90614和CC2430的母豬體溫實時監(jiān)測節(jié)點,遠(yuǎn)程、實時監(jiān)測母豬體溫。節(jié)點硬件選用CC2430單片機為主控制器,MLX90614紅外溫度傳感器為溫度測量傳感器,CC2430單片機通過SMbus協(xié)議與MLX90614通信,對讀取的溫度數(shù)據(jù)補償并發(fā)送到網(wǎng)關(guān)節(jié)點。試驗過程中,選擇母豬臀部為最佳測量部位,并研究母豬臀部溫度與直腸溫度的相關(guān)性,利用分布圖法剔除異常數(shù)據(jù),對溫度測量結(jié)果進(jìn)行補償。試驗結(jié)果顯示:在實際豬舍中傳感器網(wǎng)絡(luò)節(jié)點的有效通信距離為30 m,系統(tǒng)測量誤差為0.21℃,滿足養(yǎng)殖行業(yè)對豬體溫測量誤差的要求。提出了一種非接觸式準(zhǔn)確實時測量母豬體溫方法,為母豬養(yǎng)殖的科學(xué)化、規(guī)�；峁┘夹g(shù)支撐。
[Abstract]:In order to establish a sows health model and to provide data support for analyzing the variation of body temperature during sows' delivery and estrus, a real-time monitoring node of sows' body temperature based on MLX90614 and CC2430 was developed to monitor the body temperature of sows remotely and in real time. CC2430 single chip microcomputer is chosen as the main controller of node hardware. MLX90614 infrared temperature sensor is used as temperature measurement sensor. CC2430 MCU communicates with MLX90614 through SMbus protocol, compensates the read temperature data and sends it to the gateway node. In the course of the experiment, the best measuring site was the buttocks of sows, and the correlation between the temperature of the buttocks and the rectum temperature of sows was studied. The abnormal data were eliminated by the method of distribution map, and the results of temperature measurement were compensated. The experimental results show that the effective communication distance of sensor network node is 30 m and the systematic measurement error is 0.21 鈩，
