摘要
应用Zig Bee传感器节点的硬件和软件以及上位机软件研制了一种无线倾角传感器网络系统。采用了二次温度补偿解决温度对测量精度的影响,并对无线网络的功耗进行了优化处理。实验表明:该系统的测量精度达到了±0.01°(倾角测量范围为±3°),数据采集间隔为1次/s时,平均电流仅为0.21 m A,达到了高精度低功耗的设计要求。
Develop a wireless sensor networks（ WSNs） system used for tilt angular measurement by applying hardware,software of Zig Bee sensor node and upper PC software. Adopt technique of twice temperature compensation to solve influence of temperature on measurement precision,and optimize power consumption of WSNs. The experiment shows that measurement precision of system is ± 0. 01°（ range of tilt angular measurement is ± 3°）,and the average current is only 0. 21 m A,meets the design requirements of high precision and low power consumption.
