| 中文摘要: |
| 桡动脉脉搏波蕴藏着极丰富的心血管系统生理病理信息，对心血管疾病的预防、诊断和治疗具有重要的意义。目前检测心血管的设备主要分为两类：一类为检测功能全面的台机，但体积过大，价格偏高；而另一类虽然体积小、价格低廉，但检测功能单一，两者存在较大的应用局限性。因此，采用ARM+DSP微处理器为核心，通过压电薄膜传感器实时采集脉搏波波形，经过信号调理电路处理噪声、基线漂移和工频对脉搏波的干扰，根据脉搏波波形特征和血压信息计算出10项心血管参数，系统集成μC/OS III微型操作系统和STemWin图形界面实现显示和交互功能，最后实现设备微型化、检测多样化、价格低廉化和操作简便化的市场需求。实验结果表明，系统硬件和软件设计合理，可以有效、准确地检测用户心血管参数。 |

| Radial artery pulse wave contains a very rich cardiovascular system of physiological and pathological information, it is cardiovascular disease prevention, diagnosis and treatment of great significance. The current detection of cardiovascular equipment is divided into two categories: one for the detection of a comprehensive machine, but the volume is too large, the price is high; and the other although small size, low price, but the detection function of a single, both larger application limitations. Therefore, this paper uses the ARM + DSP microprocessor as the core, through the piezoelectric film sensor real time collection of pulse waveform, through the signal conditioning circuit to deal with noise, baseline drift and power frequency interference on the pulse wave, according to pulse wave characteristics and blood pressure information Ten cardiovascular parameters were calculated, the system integration uC/OS III micro operating system and STemWin graphical interface to achieve display and interactive features, and finally to achieve miniaturization of equipment, detection of diversification, low price and easy operation of the market demand. Experimental results show that the system hardware and software design is reasonable, can be effective and accurate detection of cardiovascular parameters of users. |
