基于无线传感器网络的奶牛养殖管理定位系统

Dairy Cattle Farming Management Positioning System Based on Wireless Sensor Networks

奶牛养殖管理定位系统在无线传感器网络的监测范围内布置非常多的传感器节点来收集周围的环境信息,并将收集到的信息处理后发送出去。该研究在分析RSSI测距误差影响因素和RSSI测距均值校正的基础上,提出了基于RSSI均值校正的三边测量定位优化算法,并进行了Matlab仿真试验。最后将此改进算法应用于奶牛健康监测和定位系统的设计,结果完全满足奶牛健康状况监测和定位要求。

In the dairy cattle farming management positioning system,a lot of sensor nodes were arranged within the monitoring scope of wireless sensor networks to collect surrounding environmental information that will be sent out after being processed. In this study,based on the analysis of factors influencing RSSI ranging error and correction of RSSI ranging mean,the optimization algorithm of trilateration localization based on the corrected RSSI was proposed,and the Matlab simulation experiment was conducted. Finally,the localization algorithm was applied to the design of dairy cattle health monitoring and positioning systems,and the results fully met the requirements of dairy cattle health status monitoring and positioning.
