Design of wireless sensor network nodes based on ZigBee technology in environmental monitoring

针对环境监测具有偏远、分散、易变、多样等特点,提出一种基于ZigBee的无线传感器网络节点的设计方案。采用基于ZigBee技术的智能网络化传感器有着很明显的优势,网络容量大、功耗低、易于扩充并且支持自组织组网。根据环境监测系统的技术要求,设计了系统结构和硬件电路,并给出了软件流程。试验测试表明,该网络节点具有较好的稳定性和较高的通信效率,可以满足环境监测对无线通信网络传输及组网要求,具有较好的推广价值。

Considering environmental monitoring with the characters of farness,disperse,inconstancy and multiplicity, a design of wireless sensor network node based on ZigBee is proposed. Smart sensor network based on zigbee has obvious advantages. Zigbee network supports large capacity, low-power consumption, easy to expand and the self-organizing network. It has designed the hardware and software structure according to the technical requirment of environmental monitoring system. The results of test indicate that network nodes have good stability as well as communication efficiency, thus satisfying with the request of wireless communication network transmission and network topology in environmental monitoring. And this design has a good practical significance.
