摘要
基于89C2051微处理器的便携式心电监护系统通过89C2051微处理器接收从主机板传来的控制命令,完成对导联的选择、心电和呼吸信号增益调节的控制,采集心电、呼吸波信号,监测导联脱落信息并将数据实时送往主机板等,为采集心电信号和检测胸腔阻抗信息提供依据。整个结构采取模块化设计,便于装卸、调试、维修以及系统扩展、升级,有较好的实用与推广价值。
This paper briefly introduces the portable electrocardiogram monitor based on 89c2051 microprocessor,its design principle and software flow.This system has the functions of collecting electrocardiosignal and checking thoracic impedance data.
