【摘要】 如何按照运动员个人生理情况安排训练计划、如何更有效地进行日常训练是教练员、运动员、队医们非常关注的问题。心血管功能对于运动员来说至关重要,而心血管血流参数是反映运动员的生理机能和心血管状态的重要生理学指标。目前,在运动员训练期间,对心血管状态的了解仅靠实验室检查,缺乏快捷、实时、现场的检测手段,因此会错过很多的关键生理状态、生理过程的评价,直接影响到对训练的监控以及运动成绩的提高。本课题的目的就是在原有的研究基础上,开发出便携的、能够在运动场地实时检测心血管功能的检测仪器,帮助教练员、队医随时随地观察运动员的心血管功能状态,了解运动员对训练计划的适应能力、心脏储备能力和恢复情况,为运动员选材、科学训练提供客观依据,因此具有非常重要的应用价值。本文利用了现代嵌入式系统发展的近期成果,围绕嵌入式系统在血流动力学检测领域中的实际应用展开了讨论。在整体结构上,处理器采用基于ARM920T内核的S3C2410A高速应用处理器,操作系统采用Windows CE实时嵌入式操作系统。本文首先详细讨论了检测系统的硬件设计。整个硬件体系包括一个以处理器为核心、SDRAM和NAND Flash作为存储设备的最小系统,采用了适合便携式应用的电源管理,集成了各种外设,如显示器接口、以太网接口、USB接口、串口、SD/MMC接口等,同时针对脉搏波特点设计了模拟信号放大、滤波电路。接下来详细讨论了Windows CE操作系统的移植与定制,具体介绍了BootLoader、BSP以及驱动程序的移植,然后利用Platform Builder定制发布版本的Windows CE操作系统镜像文件。最后,介绍了针对系统的功能需求设计的应用支持软件。针对以往检测中存在的一些问题,如检测自动化程度低、检测结果不够直观简单等,本文都提出了相应的改善方法。应用软件采用MFC+Win32的方式,在Embedded Visual C++集成环境中开发。论文最后对全文作了总结,提出了现有系统的不足并对其应用作了进一步展望。更多还原

【Abstract】 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.更多还原
