Research Of Embedded Remote Health Monitoring System Based On ARM

The paper presents a kind of embedded remote health monitoring system which is mainly used in the home environment, and use ARM-Linux as the platform for the monitoring system design and research.The paper begins with the analysis of the requirements of the system, and gives the design scheme. In this scheme, the development of the remote health monitoring system based on ARM kernel is realized, and the two of hardware and software of aspects are described in detail.In the design of hardware, the design baseed on OK6410 as the core of the Samsung Corp S3C6410 as the development platform, respectively, to design the temperature and pulse sensor selection, serial UART design, USB interface design and LCD touch screen design. In wireless communication, combine WIFI wireless communication technology with GPRS technology, and make the GPRS module design and WIFI module selection.In software, using Linux as the embedded operating system, and on the ARM platform for transplantation. Write the hardware driver and application based on Linux operating system.In view of the problem of measuring the body temperature and pulse rate in the system.Designed the temperature calibration based on least square method and Pulse wave filtering algorithm based on Wavelet.Finally, made the Qt operation interface for the system.After all the work, the system achieves the purpose of real-time monitoring of human body’s temperature, pulse rate, automatic alarm, and has the characteristics of low power consumption, easy operation and so on. The practical tests show that the system works steadily and the measuring accuracy is high, which can meet the requirements of the home remote monitoring.
