基于植入式RFID感温芯片的猪体温与饮水监测系统

Pig Body Temperature and Drinking Water Monitoring System Based on Implantable RFID Temperature Chip

为了实现猪体温和饮水行为的协同感知和联合数据采集,针对传统体温测量效率低、饮水量监测不准、数据可用性差的问题,将植入式RFID温度芯片应用于集中式圈舍养殖中猪体温的测量,将水流量传感器用于猪饮水行为的监测,两者配合可以实现猪身份识别码(ID)、体温和饮水行为的协同感知和联合数据采集。根据猪用自动饮水碗的结构和饮水时的场景,设计了集水流量传感器、RFID阅读器和ZigBee模块于一体的无线监控节点,开发了在猪只饮水的同时自动进行体温测量的监测系统。对芯片植入深度、体温变化和饮水行为的监测分别设计了不同的试验,结果表明:该系统可以实现对猪只不同深度体表温度、不同饮水时长和饮水量的自动监测,3种数据的自动关联和同时采集,可为猪病早期预警和诊断提供技术支撑。该系统有效避免了人工操作失误,提高了工作效率,可以满足集中式养猪场的精细化管理要求。

Aiming to achieve synergistic perception and joint data collection of pig body temperature and drinking behavior.In view of the low efficiency of traditional body temperature measurement,the inaccurate monitoring of drinking water,and the poor data availability,the implanted RFID temperature chip was applied to the measurement of pig body temperature in centralized pen housing breeding,and the water flow sensor was used for monitoring drinking water behavior.The combination of the two can achieve synergistic perception and joint data collection of pig identity ID,body temperature and drinking behavior.According to the structure of the automatic drinking water bowl for pigs and the scene when drinking water,a wireless monitoring node integrating water collecting flow sensor,RFID reader and ZigBee module was designed,and a monitoring system for automatically measuring pigs body temperature while drinking water was developed.Different experiments were designed for the monitoring of chip implantation depth,body temperature change and drinking water behavior.The experiments results showed that the system can measure the body temperature of different depths of pigs,and automatically monitor different drinking time and drinking water.The automatic association and simultaneous collection of data provided technical support for early warning and diagnosis of pig disease.The system effectively avoided manual operation errors,improved work efficiency,and can meet the fine management requirements of centralized pig farms.
