| 摘要：文中分析了MIMIC 多参数智能监护数据库存储文件的识读方法，该数据库公开发表于PhysioNET，还研究及基于STM32
和DAC8568 的多参数数据D/A回放系统，包括系统硬件工作原理和系统软件工作原理。MIMIC 多参数智能监护数据库的数据
文件对于变异性较大的生理参数采用连续采样的方式,而对于相对稳定的生理参数采用周期采样的方式，因此，多参数数据各信
号的抽样频率不同。系统首先通过VC++编程读取一个多抽样频率数据并在PC机上显示其波形，然后经过D/A 硬件设备进行
D/A转换后使用示波器输出其波形，实现输出的波形与原始的波形能同时回放。系统可作为模拟信号源，为远程多参数生理监护
仪的研制奠定了基础。 |

| ABSTRACT:The paper analyzes the MIMIC Multi-Parameter intelligent monitoring database storage file's reading method, the
database is published in PhysioNET. The paper also describes a multi-parameter data D/A redisplay system based on STM32 and
DAC8568, including the working principle of the system hardware and the working principle of the system software. The MIMIC
Multi-Parameter intelligent monitoring database's data file for the large variability of physiological parameters use continuous sampling,
and the relatively stable physiological parameters use periodic sampling. Therefore, Multi-parameter data for each of the signal sampling
frequency is different. Firstly, the system through VC++ programming to read more than one sampling frequency data , and display its
waveform in the personal computer. Secondly, after the D/A conversion of the D/A hardware equipment, using oscilloscope output its
waveform. The output waveformwith the original waveformcan be playback simultaneously. The systemcan be used as an analog signal
source, and laid the foundation for the development of remote multi-parameter physiological monitor. |
