| 摘 要： | 本文给出了各种生理信号数据生成系统的设计思路及其应用实例。该数据生成系统可将扫描仪得到的或画图软件画出的各种生理信号波形图自动转换为8位、10位、12位等数据,同时也可以将数据通过计算机串口将数据传送给单片机AT89S51,并利用单片机把数据写入数据存储器,如24CXX,93CXX,AT28CXX,为D/A转换产生各种生理信号提供方极大的方便。

| Abstract: | The new idea of design and an example of application about generating physiological signal data were given in this paper.Different bits data such as 8 bits,10 bits,12 bits,which based on wave picture obtained by scanner or software for drawing picture,can be produced automatically and may be send to AT89S51 microchip through serial interface.In addition,the data can be written into memory such as 24CXX,93XX,AT28CXX.Therefore,it was very convenient to produce all kinds physiological signal by digital to analog conversion. |
