摘要
针对广西山区茶园设计了依靠节点自组织特性自动构建零通信费的ZigBee无线网络监测系统,能够定时采集茶园的空气温湿度、土壤温湿度和光照等参数。该系统除协调器外全部使用路由节点,种植区按蜂窝状划分,每个路由监测节点均布置在蜂窝中心,有效提高了监测系统可靠性。在种植区与监控中心之间的非种植区设计了路由中继节点,用于接力传送茶园监测数据至监控中心内的协调器。节点硬件电路包括核心板与底板,核心板设计了CC2530与RFX2401射频功放,底板设计了传感器处理模块、电源模块及调试接口。深入分析了Z-stack协议栈基于事件处理的多任务构架下用户程序设计方法。完成了山区茶园基于ZigBee技术的无线监控网络设计,实现了茶叶种植区内空气温、湿度及土壤温、湿度,光照参数,CC2530供电电压和工作温度的周期采集和传输。通过实际运行,整个系统稳定可靠。
The paper designs ZigBee wireless network for tea plantation in Guangxi mountain area,which has features of self-organization,self-establishing and no communication fees.The network can obtain data regularly that contain temperature and relative humidity of ambient and soil,intensity of illumination.The all node of system adopts routing node except coordinator.In order to improving reliability of monitoring systems,the tea plantation is divided into several cellular areas,and the center of each cellular has one routing node for gathering above-mentioned parameters.Between tea plantation and monitor center some routing nodes are arranged so that data from tea plantation can relay transmit to coordinator which is in the monitor center.The hardware is consist of core board and baseboard.Module of sensor signal process,power module and debugging interface are equipped in the baseboard.Programming method about Z-stack protocol which is based on event process of multitask architecture was analyzed deeply.Stability and reliability of the whole system are confirmed by running actually.
