具有通信功能的电子血压计的设计

Design of Electronic Blood Pressure Monitor with Communication Function

随着电子血压计的家庭化,为了对人体的血压值进行长时间的动态监测,我们需将测量的血压值存储起来以便观察分析。但目前市场上的电子血压计大多都没有接口可以与计算机直接进行数据传输。介绍了一种应用于家用电子血压计与计算机进行数据传输的接口方案,采用AVR单片机与9针RS-232串口,实现了血压数据的无失真传输。分析了血压测量方法和原理,设计了基于AT90S8535单片机为控制核心的带串口的电子血压计,实现电子血压计数据与计算机的快速无失真传输,克服了大多血压计没有数据传输接口的弊端。

As the familialization of the electronic blood pressure,we need to store up the results in order to carry out a long time dynamic monitoring and analyze.But at present,many electronic blood pressure monitors have not interface that can transmit data with computer on the market.The paper introduces a blood pressure monitor which used at home with computer interface for data transmission scheme.The blood pressure monitor use AVR microcontroller and 9pin RS-232 serial port,transmitting the blood pressure data what achieve without distortion.The paper analyzes the blood pressure measurement methods,which are based on AT90S8535 microcontroller with a serial port for the control of the core design of the electronic blood pressure monitors,which achieves rapid and distortion free data transfer from electronic blood pressure monitors to computers.The electronic blood pressure monitor overcomes the disadvantage that most ones have not the data transmission interface.
