嵌入式多协议转换器的研究

摘要

This design gives out embedded software and hardware multi-protocol converter practical solutions. The system hardware includes RS-232 interface module, USB interface module, Ethernet interface module, memory module, power module, CPU module and other parts. Samsung' s ARM9 S3C2440A processor is chosen as the CPU. The software is based on embedded LINUX system architecture. After practical testing, the conversion allows the original low-rate, short-distance transmission serial devices access over Ethernet fast and reliable, to achieve the modernization of remote management system and achieves satisfactory results.%设计给出了嵌入式多协议转换器软硬件实际解决方案.系统硬件部分主要包括RS - 232接口模块、USB接口模块、以太网接口模块、存储器模块、电源模块、中央处理器模块等部分.中央处理器采用三星公司的ARM9 S3 C2440A.软件部分基于嵌入式LINUX系统架构.实现了RS - 232、USB与TCP/IP协议间的转换.经过测试,该转换器使原有低速率、短距离传输的串口设备能够可靠快速地接入以太网,实现系统的现代化远程管理.
