摘要
介绍了一种便携式心电监护仪的总体设计思路。系统以C8051F320微处理器为控制核心,采用高精度放大器AD620作为前置放大,低功耗图形点阵液晶显示模块MZL05-12864对采集到的心电信号进行实时显示,用大容量FLASH存储器AT45DB321作为存储芯片。该监护仪可记录压缩后的24小时心电信息,通过USB与PC机通讯,可回放心电波形。具有体积小、功耗小的特点。
This paper describes a design of portable ECG monitor. This system used the microprocessor C8051 F320 as controller, using high precision amplifier AD620 as the preamplifier, using low-pow dissipation graphics lattice LCD screen to Real-time display the collected ECG signal, and using the big content Flash memorizer AT45DB321 as memory. The monitor can memorize the compressed ECG singal of 24 hours, communicate with PC by USB and repeat the ECG. The system is small bulk and low-power dissipation.
