The article improved and designed a software and hardware system to detect the temperature and movement da-ta of Cow based on ZigBee wireless transmission network, which includes the sensor node deployed on cow tail to obtain the data,coordinator node to build the net and upload data and computer interface software. The data of cow was obtained by DS18B20 temperature sensor and MMA8451 three axis acceleration sensor. The sensor node was deployed on the tail of cow, monitoring the information of each cow, upload the data to computer through the COM port of coordinator, and show the data by computer interface software. The test showed that this system could transmission stable,low packet loss rate is less than 5% and error rate is less than 1.75%, which can provide the decision-making basis for farmers.%基于 ZigBee 无线传输网络,改进设计了一套监测奶牛体温、加速度的软硬件系统,包括采集数据的传感器节点、搭建网络的协调器节点及上位机软件.奶牛的体温、加速度分别由 DS18B20温度传感器及 MMA8451三轴加速度传感器获取.传感器节点安装在奶牛尾部,实时监测每只奶牛的体征信息,并通过协调器节点的串口上传至计算机处理平台显示及处理.测试结果表明:此系统传输稳定且丢包率低于5%,传感器获取的数据误差平均值为1.75%,可为奶牛健康养殖提供决策依据.
