基于ARM技术的嵌入式网关设计

为解决楼宇自动化系统中不同串行通信协议之间的软件接口问题，从而真正实现现场设备的远程监控与管理功能。为此提出了通过嵌入式网关实现不同串行通信协议到以太网协议的转换方案。嵌入式网关采用结构化设计，其核心的协议转换模块采用了基于ARM7TDMI 内核的32 位处理器，内嵌μCLinux 操作系统。该网关实现了楼宇自动化系统中不同串行通信协议之间的转换，实现
了统一监控的要求。

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.
