介绍了一种以低功耗单片机ATmega128L为核心的无线传感器网络节点的设计方案。所实现的无线传感器网络硬件平台由一个轻便的控制引擎支持,以开放、模块化控制架构来适应具有高度分布性的应用环境,在降低无线传感器网络硬件系统的价格和能耗的同时,提高了系统的开放性、灵活性和可扩展性。
In this paper, a design concept of wireless sensor networks ( abbreviated as WSNs) node based on low-power chip ATmega128L is introduced. The WSNs hardware platform is supported by a portable control engine and an open, modularized control structure, which can easily adapt to highly distributed environment. Besides the achievement of reduction of price and energy-consumption of wireless sensor network, it makes also an improvement on system openness, flexibility and expandability.
