摘要
对地域上分散的农业对象实现无线数据传输逐渐成为农业监控系统的研究热点。探讨Z-Stack协议栈下基于2.4GHz频带传输CO2浓度的农业环境节点设计,包括ZigBee协调器节点网络组建ZigBee路由节点和终端入网ZigBee数据传输CO2传感器输出标定以及曲线拟合等,该节点的传感器响应快速,适于安装到有线网络延伸不到的区域。
In recent years,research for geographically dispersed agricultural objects to achieve wireless data transmission control system has become the study focus of agriculture.An agricultural environment CO2 node which is based on the Z-Stack protocol,and this node transmits CO2 concentration under 2.4 GHz frequency band.The node hardware based on the CC2530 processor,the main contents include ZigBee coordinator node＇s network formation,ZigBee routing and terminal node＇s joining network,ZigBee data transmission,CO2 sensor output Calibration and curve fitting and so on.The node designed in this paper proved by experiments that it can not only achieve variety,flexible and stable network mechanism,fast response of the sensor,but also easily install to areas cable network cannot be extended to or equipment difficult to install to,and really solution ＂The last one kilometer＂ problem
