一种新型多用无线传感器网络平台硬件设计与实现

在分析了无线传感器网络特点的基础上,基于应用广泛的新型51核心单片机设计了一种新型多用硬件节点,此节点可搭配多种无线射频模块,论述了该节点的设计思路与设计方法,根据设计要求制作硬件实物并对该平台的功耗、无线数据传输距离和丢包率参数做出评估。在搭配Si4432无线模块时,该平台最大功率仅为280mW;无线通信距离为120m,丢包率仅为0.667%。硬件测试结果表明：该平台设计灵活、功耗低,满足无线传感器网络硬件节点要求,具有一定的应用价值。

Design and implementation of a new multi-use WSNs platform hardware

On the basis of analysis on feature of WSNs,a new kind of multi-use hardware node based on widely applied MCS—51 MCU is designed,it can collocate with multiple wireless RF module,design idea and method are described,material object product is fabricated according to design requirement,and three kinds of parameter,power consumption,wireless data transmitting distance and packet loss ratio are evaluated.When Si4432 RF module is used during the test,the max power support is only 280 mW and wireless communication distance is120 m,packet loss rate is 0.667 %.Hardware test result shows that the design of platform is flexible,power consumption is low,which meets the requirement of design of WSNs hardware node,so the platform has practical value.
