Abstract
In this paper, a Web-based management system for the building network is described. We developed a multi-protocol converter based on SoC and embedded Linux. It requires an appropriate operating system for handling protocols and an advanced development environment very similar to embedded linux. The multi-protocol converter integrates control networks of RS-485 and LonWorks devices to BAS through TCP/IP protocol or a client with Java applet. The system consists of three-tier architecture, such as BAS or clients, a multi-protocol converter, and control devices. In order to compare the feasibility of system architecture, it was applied to a small BAS system. By using UML, we modeled a Web-based control system with a unified TCP/IP socket communication and the system architecture. The developed system includes the inverter motor control system with modbus protocol for the RS485 network. The experiment results show that the multi-protocol converter using embedded Linux is a flexible and effective way to build a Web-based monitoring and control system.
