摘要
奶牛体征监测系统是农场养殖系统中重要的一部分,是判断奶牛体征、疾病、发情及产奶品质的重要指标点.现有判别方法是人工测量肛温,费时且不适合规模化养殖.本文设计了基于WIFI的智能耳标,以体温和进食量为奶牛体征检测指标.以CC3200作为WIFI发射器和处理器,结合高精度非接触式温度传感器TMP102测量牛耳温度,通过薄膜压力传感器测量进食量,在软件中实现体温和耳温差补算法.耳标将采集到的体温和进食量作为一个主题消息发送到MQTT服务器,显示端通过订阅相关的主题消息来接收信息.采用纽扣电池供电,CC3200低功耗管理,使耳标的使用寿命可达两年以上.在节省人力的同时,提高了奶牛监测的效率.
The cow signs monitoring system is an important part of the farm farming system. It is an important indicator point for judging the signs, diseases, estrus and milk quality of dairy cows. The existing discriminating method is to manually measure the rectal temperature, which is time-consuming and not suitable for large-scale breeding. In this paper, a smart ear tag based on WIFI is designed to measure the body signs of cows with body temperature and food intake. CC3200 is used as WIFI transmitter and processor, combined with high-precision non-contact temperature sensor TMP102 to measure the temperature of the ear, and the film pressure sensor measures the food intake, and realizes the body temperature and ear temperature difference compensation algorithm in the software. The ear tag sends the collected body temperature and food intake as a topic message to the MQTT server, and the display terminal receives the information by subscribing to the related topic message. Powered by button battery, CC3200 low power management, the life of the ear tag can reach more than two years. While saving manpower, it has improved the efficiency of dairy cow monitoring.
