基于ARM9的多协议异构开发平台的设计与实现

摘要

本文提出了基于ARM9的多协议异构开发平台的硬件设计方案，研制物联网多协议网关样机，屏蔽硬件细节差异，对不同硬件平台功能模块提供统一调用接口，传感网研究所使用的频段主要分布在433MHz (433 MHz -434.79 MHz)、470 MHz (470 MHz -510 MHz)、780MHz (779 MHz-787 MHz)、2.4GHz (2.4 GHz-2.4835 GHz)频段上，WSN子网物理层通过上述四个频段接入网关。网关的传感网一侧支持IEEE 802.15.4标准和IEEE 802.11标准，另一侧支持以太网及Internet，TD-SCDMA等3G移动通信网等。%In this paper, the design of heterogeneous multi-platform, based on ARM9, is proposed. The research is based on multi-protocol gateway prototype, which shields hardware details in different hardware platforms and provides the same function module interfaces. The band is mainly distributed in the 433MHz (433 MHz -434.79 MHz), 470 MHz (470 MHz -510 MHz), 780MHz (779 MHz -787 MHz), 2.4GHz (2.4 GHz -2.4835 GHz), WSN physical subnet layer can be accessed into gateway in above four bands. IEEE 802.15.4 standard and the IEEE 802.11 standard will be supported on one side of gateway, at the same time, Ethernet and Internet, TD-SCDMA and other 3G mobile communications network is supported on the other side.
