摘要:
 无线环境监测是ZigBee技术应用研究的重点,在农业生态系统以及工业环境中有非常广泛的应用。目前关于环境监测系统的研究多集中在2.4 GHz频段,该频段有较宽的带宽和比较高的数据速率,然而传输距离较短。文中针对2.4 GHz ZigBee物理层传输距离短的问题,提出了利用915 MHz射频芯片构建ZigBee硬件模块的解决方案。文中设计了基于ZigBee协议的传感器节点和协调器,阐述了节点软件设计流程,并对系统进行组网测试分析。结果表明：节点的点对点有效传输距离为480 m,误码率和错误率均低于5%,达到了预期设计要求。
Abstract:
 Wireless environment monitoring is the key of application research of the ZigBee technology which has a very wide application in the agricultural ecological system and industry environment. Lots of research on wireless environment monitoring system are focused on the 2. 4 GHz band which has the characteristics of wide bandwidth,high data rate and short transmission distance currently. Aiming at problem of short transmission distance of 2. 4 GHz ZigBee physical layer,adopt the 915 MHz RF chip to build node hardware module in the proposal. Design the sensor node and coordinator based on ZigBee protocol,expound the software design process of nodes,and test the long-distance environmental monitoring system in this paper. Analysis results show that the effective point-to-point transmission distance is 480 meters,bit error rate and error rate are lower than 5%,which meet the desired design requirements.
