Abstract: This paper designs a new portable vital signs monitor system. It not only can monitor electrocardiogram, breath rate, pulse rate, body temperature and other vital signs accurately, but also can run stably. The main processor, TMS320F2812, a kind of Digital Signal Processor(DSP), controls the functional modules, such as A/D convertor, LCD display and the communication between the hardware system and PC. Taking full advantage of DSP, the system is of low consumption and can be made into small size. This multi-function monitor can meet demands of service in the community and family ward.

Key words: monitor, Digital Signal Processor(DSP), vital signs

摘要： 设计一种新型的便携式生命参数监护系统。该监护系统能实现心电、呼吸频率、脉搏以及体温等多项人体生命参数的监测，且性能稳定。以数字信号处理器(TMS320F2812)为核心控制芯片，实现对系统中其他模块的控制功能，完成A/D采样、LCD液晶显示，及与PC机的通信等功能。该系统充分利用DSP的优势，仪器体积小、功耗低，是一种适用于社区医疗和面向家庭的新型多功能监护仪。
