摘要
电子血压计使用简单方便,所得数据客观稳定。本文从示波法血压测试原理出发,设计出电子血压计的系统原理框架。然后以AT89S51单片机为核心,采用BP300T型压力传感器和RS232通信电路,并结合合适的单片机内嵌软件,实现可以与计算机交互的电子血压计。特点是可以与PC机通信,血压测量受PC机控制,由PC机对被测人的血压状况进行监测、分析、存储,因此本系统可在体格检查、医疗监护等各个领域获得广泛的应用。
Digital blood pressure monitor is easy to use and the data is objective and stable. We work out the system structure of digital blood pressure monitor according to the principle of oscillography. Then werealize the hardware structure by using MCU AT89S51, sensor BP300T ,RS232 circuit and so on. The blood pressure monitor can communicate with PC combined with proper firmware. PC can monitor, analyze and store the data of blood pressure and our system can be widely used in the field of physical examination, medical surveillance and so on.
