针对农业生产环境中信息监测点分散和有线数据传输方式的局限性。以射频芯片CC2430为平台,利用新型无线通信技术ZigBee的易扩展、成本低和功率小等优点。在研究网络组建、系统绑定和数据传输的基础上,开发了基于ZigBee的无线传感器网络。并利用CC2430的睡眠模式和通过选择性发送数据措施实现终端节点的低功耗。实验结果表明:该传感器网络能实时监测温度、光照等环境参数,且终端节点有着较好的节能效果,满足对农业环境分散点实时监测的要求。

According to the dispersion of information monitoring point and the limitation of wire transmission in agricultural production environment. Based on the platform of CC2430 RF chip, a new wireless communication technology of Zig Bee was utilized because it has some advantages such as easy to extend, low cost and low power. A wireless sensor networks （ WSNs ） based on Zig Bee was developed on the basis of resarch on building of network, system binding and data transmission. At the same time, low power was implemented in terminal nodes by adopting the sleeping mode of CC2430 and the selection of sending data. The experimental result indicates that the network can monitor the temperature, illuminance in real time and the terminal nodes of this network can effectively save energy, which satisfy the demand of monitoring of the dispersive point information in agricultural environment.
