摘　　要：本文叙述了一种通过计算机串行口获取心电图机模拟输出信号的方法。传统心电图机只提供模拟量输出,本文采用模数转换芯片在单片机控制下进行模数转换,再通过单片机的串行口发送的方法将心电图数据发送到计算机。计算机上则采用Visual Basic编写的程序描记和保存接收到的数据。制作的实验样机圆满地实现了上述功能。This article describes a method for receiving output of electrocardiograph through serial poll of PC. The output of electrocardiograph is first transformed by ECC adapter.and then is analoges-to-digital transfered. The result is sent to PC by microcontroller through serial port. Program written by Visual Basic language running on PC can draw and record the data received from serial port. The experiment equipment accornpish the function successfully.
