Abstract:

This paper presents a multi-interface embedded server architecture for remote real-time monitoring system and distributed monitoring applications. In the scheme, an embedded microprocessor (LPC3250 from NXP) is chosen as the CPU of the embedded server with a linux operation system (OS) environment. The embedded server provides multiple interfaces for supporting various application scenarios. The whole network is based on local area network and adopts the Browser/Server (B/S) model. The monitoring and control node is as a browser endpoint and the remote node with an embedded server is as a server endpoint. Users can easily acquire various sensors information through writing Internet protocol address of remote node on the computer browser. Compared with client/server (C/S) mode, B/S model needs less maintain and can be applicable to large user group. In addition, a simple network management protocol (SNMP) is used for management of devices in Internet protocol (IP) networks. The results of the demonstration experiment show that the proposed system gives good support to manage the network from different user terminals and allows the users to better interact with the ambient environment.
