用于动态心电监护仪的心电信号无线传输系统的设计
Design of wireless transmission system of ECG signal in dynamic ECG monitor
摘要
Abstract
Objective To design an ECG signal wireless transmission system for the dynamic ECG monitor.Methods The ECG signal wireless transmission system developed was composed of an ECG signal acquisition module,a wireless transceiver module,a wireless communication protocol module and a digital filtering module.The ECG signal acquisition module consisted of a digital interface circuit,an A/D converter microprocessor and an ECG amplification circuit.The wireless transceiver module was made up of a wireless RF unit,a crystal oscillator circuit,an RF circuit,a debug serial port,a register,a power supply module and a reset circuit.The wireless communication protocol module involved in a data link layer and a physical layer,of which the data link layer had two mechanisms of automatic response and frequency modulation.The digital filtering module mainly included a digital filter,a signal input module,a delay unit and a coefficient registers,and the digital filter was designed using the equiripple method and realized signal denoising by converting ECG signals into output sequences.The performance of this system for wireless transmission of ECG signals at different proximity remote transmission distances was validated with the ECG signal wireless transmission methods based on ZigBee networking and general packet radio service(GPRS)and based on wireless networking module used as comparative methods.Results The system developed gained advan-tages over the other two methods in average rate,sucess rate,average time consumption and average frequency for re-transmission of ECG signal wireless transmission.Conclusion The system developed can be used for efficient,stable and clear ECG signal wireless transmission for the dynamic ECG monitor.[Chinese Medical Equipment Journal,2024,45(6):28-32]关键词
