中文摘要:

      通过ZigBee技术、GPS定位追踪技术和远程无线通信技术的结合，计算了ZigBee节点传输距离，并提出一种双系统的监测牛群数量的策略，通过对系统误报率的分析，设定误报率门限，从而确定双系统的组成方式，提高牛群数量监测的准确性，降低误警概率。在此基础上设计了一套智能牛群检测系统，并通过实验验证了理论计算结果。该系统可以在无人值守的情况下，自动监测草原牧场上牛群数量并记录牛群位置，实现自动上传功能。

英文摘要:

      Through the combination of ZigBee technology,GPS tracking technology and remote wireless communication technology,the transmission distance of ZigBee nodes is calculated and a double system strategy for monitoring cattle herd is put forward.The false alarm rate threshold is set within the analysis to determine the composition of the dual system,improve the accuracy of the cattle herd monitoring and reduce the false alarm probability.On the basis of above,an intelligent cattle detection system is designed and the experiments verify the theoretical calculation results.The intelligent system can monitor automatically the quantity of cattle herd on the grassland in the case of unattended and record the cattle location,then upload automatically.
