The Design On Portable Cardiovascular Function Detecting System Of Athletes

How to arrange the training plan and make the training more effective according to personal physiological instance is the common spot which the coaches, atheletes, team doctors care. Cardiovascular function is extremely important to atheletes, and the cardiovascular parameters are the crucial physiological indexes which can reflect the physiological enginery and cardiovascular state. At present, while in the training of atheletes, the knowing of cardiovascular state is only realized by lab examination, the lack of convenient, real-time, spot detecting means causes the missing of evaluation to many critical physiological state and process, directly affecting inspection to training and improvement of grade. The aim of this project is to design a kind of portable detecting equipment which can real time detect cardiovascular function, helping coaches and doctors observe the heart function of athelets, know the adapting ability, heart storage ability of atheletes, providing impersonal basis for person selecting and scientific training, so, it would have very important value in application.This paper uses the latest result of embedded system, and discusses the application of embedded system in cardiovascular detecting field. In the whole structure, we adopt rapid application CPU S3C2410A based on ARM920T kernel, and Windows CE real time embedded system. Firstly, the paper discusses the hardware design of dectecting system. The hardware architecture embraces the CPU, SDRAM, and NAND Flash, it adopts the power management which is suitable for portable applications, and it also integrates various external devices, including LCD display, Ethernet, USB device, UART, SD /MMC, and the analog signal circuit of amplification and filtering according to the characteristic of pulse wave. Then, we amply discuss the transplant and customization of Windows CE, introduce the replanting of BootLoader, BSP, and device driver, make the retail edition of Windows CE image by using Platform Builder. Last, we discuss the application software aiming at the function of detecting system, we give some solutions to some problems in previous detecting. The software is design by Embedded Visual C++ using MFC+Win32.Finally, we make a summarization to this paper, indicating some disadvantage in the existing system and making an further expectation.
