摘要
针对心电模块设计中无线传输心电数据的需求,以提高应用的灵活性和心电设备的移动性。采用了低噪声、高精度、高共模抑制比的仪表放大器设计了心电放大和滤波通道,将RF技术与高性能、低功耗的msp430单片机应用到心电监护模块的设计中,实现了心电数据的采集,无线传输与信号处理。该设计方案具有高效,低成本的特点,充分发挥了2.4GHz RF技术的无线优势,具有较高的应用价值。
An innovative design of the ECG Monitor module is proposed in this paper, which enhances the flexibility and mobility of monitors. This module employs a low-noise, high precision and a high Common-Mode-Rejection-Ratio instrumentation amplifier to design the ECG amplification and the filtering channel, and wireless transmission of the ECG data is implemented through the radio frequency technology（RF）with a high performance and low-power consumption MCU of MSP430 series. The ECG data can be acquired, transformed and processed by the monitor model itself. The resuits indicate that the scheme is efficient and low-cost. It takes full advantages of 2.4GHz wireless RF technology and it is practical in the medical applications.
