采用以太网控制器ENC28J60,建立一种网络化数据采集的方法,并应用于心电的远程监护系统.详述了系统设计的原理和软硬件的实现方法,采用AVR的ATmega128为主控单片机,能够将测量数据通过TCP/IP协议传输至上位机,实现了心电数据的实时采集与显示.实验例证,该系统具有性能稳定、兼容性强等特点.%By using the ethernet control chip of ENC28J60, the network data acquisition method wasrnestablished,and applied to the remote electrocardiogram monitoring system. The design principles, and thernimplementation of hardware and software were shown in details. Using AVR ATmegal28 to the microcontroller,rnthis system was able to transmite data to upper computer by TCP/IP, and the electrocardiogram signals couldrnbe collected and displayed in real-time. Practice shows that the system has features of stable performance andrnstrong compatibility.
