【目的】设计果园环境监测系统.【方法】该系统由远程ZigBee-GPRS网关与无线传感器网络(WSN)节点组合,果园参数在WSN、GPRS与Internet间进行采集与传输,实现远距离果园环境实时监测.节点采用CC2530作无线数据收发芯片,GPRS采用ComWay模块,由ZigBee进行组网采集环境信息,通过GPRS网络回传给上位机实现实时监测,再由决策支持系统进行分析发送指令控制节点电磁阀通断从而营造一个适合果树生长的环境.【结果和结论】试验表明:系统可完成传感网与移动通信网络之间的数据传送,实现不同类型感知网络之间的协议转换以及对传感器网络的部分管理控制功能.系统在果园中运行稳定并且丢包率低于10%,具有实践应用价值.
【Objective】 Orchard environmental monitoring system was designed. 【Method】 The system was composed of remote ZigBee-GPRS gateway and WSN nodes, and the orchard parameters were collected and transmitted between WSN, GPRS and Internet to realize real-time remote orchard environment Monitoring. Node using CC2530 as a wireless data transceiver chip, GPRS using ComWay module by ZigBee network environment information collected through the GPRS network back to the host computer to achieve real-time monitoring, and then by the decision support system to send commands to control the node solenoid valve Off to create a suitable environment for the growth of fruit trees.Results and Conclusions The experiment shows that the system can complete the data transmission between the sensor network and the mobile communication network and realize the protocol conversion between different types of perceptual networks and the sensor network Part of the management and control functions.The system is stable in the orchard and the packet loss rate is less than 10%, which has practical value.
