项目摘要

Teh obejctije ot the project is to develop a monitoring system of physoilogical and diomechnacal functions of human body during physical exerices. The system has been designed so that it is capable of measuring and processing various kinds of biological functions if one function is allowable at a time.The system consists of a protable unit, a stand alone interface unit and a microcomputer system PC9801VM2. The portable unit includes two 8 bit microprocessors, one of which, MPU -1, receives up to 8 channels input data adn does some kinds of data processing and the other, MPU-2, controls a real time clock unit, remote control switches and a voice synthersizer which converts numvberical output from the MPU-1 to correponding voices.The data processing program and resultant data are written in a memory card (128kB), which is easily exchageable with ohter card including different software. R-R intervals of exercies ECG are chosen as a biological function to be impelmented first in this system. An algorithm for derecting QRS from ECG in real time has been developed using a newly revesed correlation filter. The filter has a capability of detecting QRS waves from noisy exercise ECG and of determining the time od their occueeences with the time resolution of i ms. This ECG monitoring system also indicates contrmparary heart rate vocally. This capability proved to be very useful in controlling the amount and intersity of work load for avoiding dangerous over load or practicing precisely programmed exercise.Recoede data on the memory card are transferrcd to the microcomputer system PC9801VM2. Data filing system for long term observation of functions of indeviduals, some soltware for visualizing ans analyzing and analyzing the obtained data are implemented in the microcomputer system.

该项目的目的是开发一个人体运动过程中生理和机械功能的监测系统。该系统的设计使其能够在一次允许一种功能的情况下测量和处理各种生物功能。该系统由便携式单元、独立接口单元和微计算机系统PC9801VM2组成。该便携式单元包括两个8位微处理器，其中一个MPU-1接收多达8个通道的输入数据并进行某些数据处理，另一个MPU-2控制实时时钟单元、遥控开关和语音合成器，将MPU-1的数字输出转换为相应的语音。数据处理程序和结果数据写入存储卡（128kB）中，可以轻松地与其他卡（包括不同的软件）进行交换。选择心电图练习的 R-R 间隔作为该系统中首先实施的生物功能。使用新修订的相关滤波器开发了一种实时从 ECG 中去除 QRS 的算法。该滤波器能够从嘈杂的运动心电图中检测 QRS 波，并以 i ms 的时间分辨率确定它们出现的时间。该心电图监测系统还可以通过声音指示对比心率。事实证明，这种功能对于控制工作负荷的数量和强度，以避免危险的超负荷或进行精确编程的锻炼非常有用。存储卡上的记录数据传输到微机系统PC9801VM2。在微机系统中实现了用于长期观察个人功能的数据归档系统，以及用于可视化和分析所获得的数据的一些软件。
