基于ARM技術的嵌入式網(wǎng)關設計

為解決樓宇自動化系統(tǒng)中不同串行通信協(xié)議之間的軟件接口問題，從而真正實現(xiàn)現(xiàn)場設備的遠程監(jiān)控與管理功能。為此提出了通過嵌入式網(wǎng)關實現(xiàn)不同串行通信協(xié)議到以太網(wǎng)協(xié)議的轉換方案。嵌入式網(wǎng)關采用結構化設計，其核心的協(xié)議轉換模塊采用了基于ARM7TDMI 內(nèi)核的32 位處理器，內(nèi)嵌μCLinux 操作系統(tǒng)。該網(wǎng)關實現(xiàn)了樓宇自動化系統(tǒng)中不同串行通信協(xié)議之間的轉換，實現(xiàn)
了統(tǒng)一監(jiān)控的要求。

Abstract：A solution for performing conversion between different serial communication protocols and Ethernet protocol by means of the embedded gateway is presented in order to provide interoperability between communication equipment utilizing different communication protocols and the building management system，offering remote monitoring and managing function for field devices. The embedded gateway employs modular design with its protocol conversion module based on 32-bit ARM7TDMI processor and using embedded μCLinux operation system. This can provide conversion for a variety of serial communication protocols in the building automation system and meet requirements of compliant monitoring.
Keywords：Embedded gateway Protocol converting module Monitoring
