摘要: 傳統(tǒng)生豬體溫測量一般使用水銀溫度計測量生豬直腸溫度來確定體溫,該方式不能做到對生豬體溫的實時監(jiān)測,。系統(tǒng)設(shè)計了一種基于物聯(lián)網(wǎng)技術(shù)的生豬體溫監(jiān)測系統(tǒng),。采用ESP8266作為主控制器和無線通信模塊,溫度傳感器使用MF54系列的NTC熱敏電阻,,軟硬件上采用非平衡橋電路和平均值濾波法,,使得測量數(shù)據(jù)的精度達到±0.1 ℃。因生豬具有活動性,,監(jiān)測節(jié)點集成在豬耳標上,,通過采集耳腔溫度來實現(xiàn)體溫的實時監(jiān)測,。平臺層使用移動OneNET物聯(lián)網(wǎng)平臺,,開發(fā)了移動端應(yīng)用作為監(jiān)測系統(tǒng)的顯示終端,。系統(tǒng)實現(xiàn)了對生豬體溫的實時監(jiān)測,對生豬疾病預(yù)防和智能化養(yǎng)殖有一定的應(yīng)用價值,。

Abstract: Traditional pig temperature measurement generally uses a mercury thermometer to measure the rectal temperature of the pig to determine the body temperature. This method cannot achieve real-time monitoring of the pig temperature. The system designed a pig temperature monitoring system based on the Internet of Things technology. The ESP8266 is used as the main controller and wireless communication module. The temperature sensor uses MF54 series NTC thermistor. The software and hardware adopt unbalanced bridge circuit and average filtering method, so that the accuracy of the measured data reaches ±0.1 ℃. Due to the activity of live pigs, the monitoring node is integrated on the ear tag of the pig, and the real-time monitoring of the body temperature is achieved by collecting the ear cavity temperature. The platform layer uses the mobile OneNET IoT platform, and develops a mobile application as the display terminal of the monitoring system. This system realizes real-time monitoring of pig body temperature, which has certain application value for pig disease prevention and intelligent breeding.

近年來,,在大規(guī)模養(yǎng)殖過程中,隨著養(yǎng)殖規(guī)模與生豬品種的增多,,豬的發(fā)病率也逐漸增多,。體溫是判斷生豬疾病的主要生理指標,一般豬感染傳染病時,,體溫會發(fā)生明顯變化,。體溫是診斷生豬疾病重要依據(jù)之一,也是給病豬用藥的重要依據(jù),。觀察生豬的體溫變化,,有助于對豬病做出判斷[1]。
傳統(tǒng)的生豬體溫測量方式一般使用直腸測溫法,,此操作方法操作難度大,,而且只能單次測量,不能做到對體溫數(shù)據(jù)的實時監(jiān)測,,使得養(yǎng)殖人員無法第一時間對生豬的健康問題做出有效的措施與預(yù)防,。隨著無線通信技術(shù)與物聯(lián)網(wǎng)技術(shù)的發(fā)展,在大型養(yǎng)殖場實現(xiàn)智能體溫監(jiān)測是必然的趨勢,。因此設(shè)計出能實時監(jiān)測生豬體溫的系統(tǒng),,能夠盡快發(fā)現(xiàn)病畜的早期癥狀,在疾病大面積爆發(fā)之前,,實現(xiàn)有效的隔離和控制疾病的傳播[2],。
