Telemedicine Web Server Based on Embedded Serial Device

An Embedded Web Server is a web server that runs on an embedded system. The embedded web server technology is the combination of embedded device and Internet technology. Therefore, if any new technologies and algorithms for monitoring such as Internet, web server and embedded system can be integrated, then a more comprehensive, efficient and effective data acquisition can be realized. It is the server that can be configured by the user in order to monitor various physiological parameters of the patients. This paper is focused on realization of TCP/IP suite and user development platform for this embedded web server. The embedded web server design includes a complete web server with TCP/IP support and Ethernet interface. The web server reference design includes complete source code written in C-language. Such designs consume a few bytes of memory especially for microcontroller based embedded systems. The development uses the microcontroller from Philips and the Ethernet controller from Microchip. It also offers good performance while using fewer resources, resulting in cost reduction, high speed and low power consumption which are desirable in embedded applications. Finally as a case study, monitoring of temperature and heart rate is discussed in this paper.
