开放式的无线传感器网络节点平台设计

摘要

无线传感器网络是一种应用相关的网络.不同的应用背景需求不同的无线传感器网络节点.硬件的相关性太强不利于向其他平台移植.为解决该问题,利用硬件的模块化的设计思想,我们设计了一种开放的可扩展的无线传感器网络节点平台.该平台以MSP430F5438微处理器作为主控芯片,以CC2420作为射频控制芯片.实验证明该平台具有低功耗、开放式以及可扩展等特点.%Wireless sensor network is a network which is related to specific application backgrounds. Different wireless sensor network nodes are needed in different application backgrounds. If a wireless sensor network node is unmodifiable in hardware, it will has great disadvantage in applying to other platforms. In consequence,an open wireless sensor network node platform is presented making use of modular design in hardware design. The node platform uses MSP430F5438 microcontroller as its main control chip,and CC2420 as its RF control chip. Tests show that our node platform has advantages of low power consumption and openness.
