基于嵌入式 Internet技术 ,提出一种面向设备动态驱动的异种网络互连体系结构—— Webit,并建立 Webit模型。该体系结构采用 thin TCP/ IP协议栈技术建立 Em bedded Web Server,实现了将现场设备接入 Internet的目的 ;构建嵌入式 XML中间件 ,实现实时多任务系统与 Embedded Web Server的集成 ,使现场可编程设备的远程监控、管理及驱动程序动态下载得以实现。 Webit体系结构使工业生产自动化系统和智能家电的远程化成为可能 ,并为其提供了技术上的支持。 Based on embedded Internet technology, this paper proposes Webit, a heterogeneous network interconnection architecture for device dynamic driver, and establishes a Webit model. The architecture adopts the thin TCP / IP protocol stack technology to establish Em bedded Web Server, and realizes the purpose of connecting the field devices to the Internet. The embedded XML middleware is constructed to integrate the real-time multi-task system and Embedded Web Server, Remote monitoring of programming equipment, management and driver dynamic download can be achieved. The Webit architecture enables the remote production of industrial automation systems and smart appliances and provides technical support.
