基于ZigBee的点到点通信质量测量仪设计

Design of Point-to-Point Communication Quality Measuring Instrument Based on ZigBee

现有ZigBee点到点通信质量测量的仪器只可对单程进行测量,且测量参数单一,不能满足工程需要。为此设计了手持式ZigBee点到点通信质量测量仪。以ZigBee的MAC层数据帧和应答帧为基础,通过两点间通信的方式实现ZigBee点到点通信质量的定量测量。可同时对往返路径进行双向测量,效率提升1倍。使用多个参数对通信质量进行表征,避免了单一参数的局限性。实验表明,仪器测量快速准确。此外,仪器还具有功耗低、体积小、质量轻、操作简单等优点,适合在ZigBee网络设计、安装、调试与优化等场合使用。

The existing measurement instruments of ZigBee point-to-point communication quality can only measure the communication quality of go path,and are only measure one parameter,which cannot meet the needs of engineering.So a new hand-held measuring instrument for ZigBee point-to-point communication quality was designed.Based on the data frame and acknowledgement frame of ZigBee MAC layer,the quantitative measures of ZigBee point-to-point communication quality is achieved through the way of communications between the two points.Two-way measurement of the round-trip path can be carried out simultaneously,which can double the measurement efficiency.Multiple parameters are used in order to avoid the limitations of single parameter.Experiments show that it is fast and accurate in measuring.In addition,it has the advantages of low power consumption,small size,light quality and simple of operation,which is suitable for the process of design,installation,debugging and optimization when layout a ZigBee network.
