摘要
介绍了基于AT89S51制作的心肺复苏模拟人控制电路,重点介绍了使用栅格尺和光电耦合器产生相对位移的方法,测量对模拟人进行人工呼吸和胸部按压时胸部起伏的幅度。电路中使用了ZLG7289组成的键盘和数码显示电路,使用了ISD4002语音电路,给出了程序流程图。
This paper introduces a novel control circuit of CPR simulator based on AT89S51.The relative displacement is generated by grid scale and opt.and elec.coupler.It is converted to amplitude of inhaling of the artificial person.Keyboard and digital display are based on ZLG7289 and the audio is based on ISD4002.A block diagram of the program is also presented in this article.
