低功耗心电分析监护仪设计

The Design of a Cardiac Monitoring and Analysing System with Low Power Consumption

研究设计出了一种低功耗的便携式液晶显示心电分析监护仪,除了对其总体方案进行了论证外,还完成了硬件和软件的设计。系统采用80196单片微型计算机为中央处理器,对实时心电信号进行数据处理和分析。该机除了具有一般监护性能外,同时还具有五种心律失常分析、报警,以及冻结、自动走纸记录功能,交、直供电,携带方便。简化硬件电路,优化软件结构,采用并实现了多种低功耗设计方法以及液晶显示模块化设计。

The paper deals with a portable analyzing monitor system with liquid crystal display(LCD), which is low in power consumption and suitable for China' s specific conditions. Apart from the development of the overall scheme of the system, the paper introduces the design of the hardware and the software. The 80196 single chip microcomputer is used as the central microprocessor to process and real-time electrocardiac signal dada.The system have the following functions: five types of arrhythmia analysis, alarm, freeze, and record of automatic paperfeed-ing.The portable system can be operated by alternate-current(AC) or direct-current (DC) .Its hardware circuit is simplified and its sofware structure is optimized. Multiple low power consumption and LCD unit are adopted in its modular designs .
