开放式生理信号产生及测量仪的研制

我们提出了一种以单片机为核心研制的开放式生理信号的产生及测量仪。该仪器使用液晶LCD显示信号波形和相关参数信息以及键盘实现人机交互 ,并采用存储常用波形的特征数据及相应的算法来产生所拟定的信号 (多种生理信号和常用信号 ) ,同时也可产生用户自定的信号 ,具有较好的开放性。另外 ,采用与计算机类似的模块设计方法 ,使其具有很好的扩展性。本仪器不仅具有显示、测量和保存生理信号等功能 ,而且还具有功耗低、体积小、成本低、携带方便等特点 ,因此该智能仪器在实验教学、临床测试和医疗仪器维修中使用方便。

Development of Opened Instrument for Generating and Measuring Physiological Signal

An opened instrument with liquid crystal display (LCD) f or generating and measuring physiological signal is introduced in this paper. Base d on a single-chip microcomputer. the instrument uses the technique of LCD scre en to display signal wave and information, and it realizes man-machine interact ion by keyboard.This instrument can produce not only defined signal in common us e by utilizing important saved data and relevant arithmetic, but also user-defi ned signal. Therefore, it is open to produce signal. In addition, this instrumen t has strong extension because of its modularized design as computer, which has much function such as displaying, measuring and saving physiological signal, and many features such as low power consumption, small volume, low cost and portabi lity. Hence this instrument is convenient for experiment teaching, clinic examin ing, maintaining of medical instrument.
