摘　　要：为了提高心电系统去噪质量和处理速度,降低整个系统的功耗和资源利用,提出了一种基于FPGA的无线动态心电监护系统设计。系统由心电采集模块、数据处理模块、显示模块和无线传输模块组成。脉搏传感器采集人体心电信号,通过Cyclone IV系列FPGA器件EP4CE6E22C8芯片对采集到数据进行数字小波变换去噪和相关处理分析;处理后的心电信号通过HMI串口显示屏对数据进行显示;同时系统采用了无线蓝牙通信技术把相应数据无线传输到服务器的上位机上显示和存储。通过软硬件测试分析,该系统能实时准确的显示人体心率脉搏的变化,测得数据与通用医学设备比较误差在3%以内,表明该系统和现有的医疗设备具有较高的一致性,具有一定的医学应用价值。In order to improve the denoising quality and processing speed of ECG(Electrocardiograph)system and reduce the power consumption and resource utilization of the whole system,a wireless dynamic ECG monitoring system based on FPGA was proposed.The system consists of ECG acquisition module,data processing module,display module and wireless transmission module.The pulse sensor collects the human body ECG signals,and the digitally-wavelet-based denoising and related processing analysis of the collected data is performed by the Cyclone IV series FPGA EP4CE6E22C8 chip;the processed ECG signals are displayed through the HMI serial display;the system is also adopted.The wireless bluetooth communication technology wirelessly transmits the corresponding data to the upper computer of the server for display and storage.Through software and hardware test analysis,the system can accurately display the changes of the heart rate pulse in real time.The measured data and the general medical equipment have an error of less than 3%,indicating that the system has high consistency with the existing medical equipment and has certain medical application value.
