The Research And The Realization Of Embedded Broadcast System Based On

With the scientific and technological progressing and living standards improving, the average life spans of people keep increasing, the community will inevitably enter the ageing and the health care needs of the elder will be great. On the one hand, elderly patients will be more willing to accept medical care under family environment, on the other hand, human physiological parameters monitoring and recording have far-reaching significance for researches on changes in the body, therefore, this paper has designed a human physiological parameters monitoring system terminal based on ARM and the accompanying professional medical bodies service system.The terminal is connected to the INTERNET via the Ethernet, implementing physiological parameters long-distance acquisition and transmission by using TCP / IP protocol. And different medical files and services are supplied for different end-users by the medical-EP.1.This article introduces the medical model that translates the human being physiological signals (including parameters of blood pressure, pulse wave, body temperature) to electronical signals, and discusses how to build mathematical and physical model based on the medical model.2.Terminal hardware design is given. The terminal uses S3C2440 processor, AD data acquisition card, LCD and touch screen. It includes memory expansion, power systems design, network connectivity circuit development. The feasibility of the easy communication between the serial equipment that based on ARM and Linux and Ethernet gateway has been proved through experiment.3. The programs of drivers under the Linux are offered, such as the design of terminal embedded system, liquid crystal display of the mainly modules, touch screen, AD, networking chips and so on . At the same time, the functional requirements and design methods of various modules of embedded terminal are described in detail.4. The designs of the system's server-side and every construction of the medical module database are discussed in detail.Finally the article concludes that the human body physiological parameters collection system based on Ethernet taking full advantages of Internet will highlight people's concern on their own physical changes, therefore it will offer a good foundation support for long-distance medical care, family health, expert consultation and other emerging medical aid.
