摘要： 研究并实现了一种基于Web技术的嵌入式设备监控模型,使管理者可以通过Internet利用Web浏览器完成对现场设备的远程访问、监控和维护等操作,实现了异构设备之间的跨平台互访。对TCP/IP协议进行约简,实现了一个thinTCP/IP协议栈,为嵌入式设备提供了网络接口,实现了与Internet的无缝连接。嵌入式设备网关将TCP/IP协议与嵌入式设备监控协议之间的格式进行转换,实现了远程用户对现场设备的透明访问,具有智能化和远程管理的特点。通过对该模型性能的测试,结果表明基于Web的远程监控方式可以满足监控任务的需要,而且能有效降低监控运行维护成本、提高运行维护效率,具有实际应用价值。

Abstract: A monitored control model Web-based for embedded devices is presented to realize the online remote supervision, management, and maintenance embedded devices using a standard Web browser over Internet. A thin TCP/IP stack, which provides the network interface for embedded devices and makes them can be connected to Internet, is implemented because of the limited resources and computing power of embedded devices. The embedded device gateway performs format conversion between TCP/IP messages and monitor instructions of embedded devices, and therefore remote users can transparently access devices over Internet. The networking and intelligent management of embedded devices can be really implemented. The performance experiment results show that the model can meet the most of network application demands and will decrease systemrunning cost and improve maintaining efficiency.
