群养母猪饮水行为监测无线传感器网络节点设计

摘要

A wireless sensor networks(WSNs) node composed of STM32 microcontroller,CC1101 radio frequency modules and RFID reader/writer module is developed for individual drinking behavior monitoring in group housed sows. Using RFID technology to identify the drinking-water sow, Recording the cow' s water intake real time with flow meter,Establishing a star network with wireless radio frequency module,and simplifying time synchronization problem of the network, Sow individual information is collected and sent to remote monitoring center via network, Achieving automatic monitoring of sow individual drinking behavior. The result shows that the recognition accuracy of drinking sow individual is 100% ,node can accurately record amount of drinking water in real time.%针对群养母猪个体饮水行为监测,研发了一种主要由STM32微控制器、CC1101无线射频模块和RFID读写器模块组成的无线传感器网络节点.采用RFID技术实现对饮水母猪个体的识别,利用流量计实时记录母猪饮水量.通过无线射频模块组成星型网络并简化时间同步问题,将采集的母猪个体信息发送至远程监控中心,实现母猪个体饮水行为的自动化监测.实验结果表明:节点对饮水母猪个体识别正确率达到100％,能够准确、实时地记录其饮水量.
