摘要
针对传统网关节点功耗大的缺点，该文设计了一种低耗能的网关节点。该网关节点的硬件平台主要由S3C2440A微处理器，K9F1208存储器芯片以及作为通信模块的DM9000A以太网芯片和CC2420无线射频芯片构成。同时，在硬件的基础上该文移植了嵌入式Linux作为实时操作系统，并将电能数据管理（PDM）模块添加到该操作系统中，根据系统各部件的工作状态对系统操作模式进行实时控制。通过实验表明，该网关节点相对于传统的网关节点而言，消耗相同的电能其工作时间比传统的延长了50％，大大降低了网关节点的功耗，节能效果显著。
For the shortcomings of traditional gateway node large power consumption, a low energy gateway node is designed. In the design, the gateway node hardware platform which contains the S3C2440A as the core, adopts K9F1208 chip memory, as well as the DM90OOA Ethernet and the CC2420 RF chip as communication module. Meanwhile, on the basis of the hardware, in this paper, embedded Linux as the real-time operating system is transplanted, and an electric energy data management （PDM） module is added to the operating system, it controls the system operating mode for real time according to the working status of the various components in the system.. The experimental results show that the gateway node in this paper compare with the traditional gate- way node, the working time is extended by 50% in the same power consumption, it greatly reduces the gateway node power con- sumption, and energy saving effect is remarkable.
