摘要
嵌入式系统以其体积小、功能多、支持以太网技术等优点而成为工控领域中的新热点。本文介绍的数据监控系统以嵌入式系统为核心 ;利用其串口与底层I/O节点相连 ,上层则直接联入Internet,允许授权的用户在Internet任意一点应用浏览器访问该系统并实现对下层设备的监控。
The embedded system has become a hot spot in process control area because of its features of small volume, multiple functions and supporting Ethernet technology. The data supervisory system introduced in this paper adopts embedded system as the kernel; and connects the serial port to its bottom layer I/O node and connects Internet directly via its top layer. The authorized user is allowed to access this system from any location by using Internet Explorer and implement supervisory of low layer equipment.
