| Increase the number of chronic disease population, the acceleration of aging population and the more stricter requirements of the quality of modern life, all these facilitated the change of people’s live view to the disease, which has been transformed from the traditional "pay more attention to treatment than prevention" to "focusing on prevention rather than treatment". So enjoying high-quality health care remotely and medical consulting services has become a pressing demand. Meanwhile, a stable and reliable home health-monitor net device is playing an important part in the normal operation of the whole system. The development of a generic, extensible, and open the health care infrastructure with network hardware platform is a vital step.Under the development environment of embedded Linux, took the core board TQ210 which is provided Guangzhou TIANQIAN as the embedded core board and STMicroelectronics company’s STM32F107VCT as the coprocessor of hard platform, after the design of peripheral module circuit, development of QT GUI program and acquisition and processing module program, a network of home health care hardware platform was successfully constructed. The digital processing and real-time analog signal access health parameters curve can be displaying on the LCD screen after connected to the specified GPIO. Specific works are included in the following four main parts:The first part was a peripheral interface and level shifting circuit hardware circuit design and debugging, peripheral interfaces, including 7-inch LCD screen, four USB ports, WIFI SDIO interface,3 serial ports, SD card, an Ethernet port and pre leave multiple GPIO ports and so on.The second part was to build the embedded Linux cross development environment, compiled the Linux 2.6.35 kernel source code and cut the unneeded module in kernel, made file-system mirror with busybox toolkit and the whole system’s migration to the home remote health monitoring hardware platform finally.The third part was the introduction of the applicability of the strong health parameters Datagram Protocol and provided a function interface of data network in order to receive WEB client or application development of intelligent terminals，or mobile phones to facilitate WEB APP developers to develop top.The fourth part was the design and and implementation the module function of the QT app,user login ,detabase management and WIFI connectivity were included.moreover,the WIFI connection can ensure a stable and reliable data transmission lines at home.After ordinary ECG acquisition board analog signal acquisition and processing board preset IO port,field test was made and the results show that the design of the home remote health monitoring network platform can achieve on an analog electrical signal processing and display the data real-time on the screen,generating valuable data file that is related to user information and can push data to aremote server and accurately via WIFI network. |
