单片机控制的LCD心电监护仪的设计

Design of a Single Chip Microprocessor-Based LCD Monitor for ECG

本文研究了一种以LCD作为显示器的单片微机(MCS-51系列)控制的心电监护及分析仪,实验结果表明,用LCD显示器代替CRT显示器构成的心电监护仪,其体积小,功耗低,显示方式灵活,可以构成便携式监护装置。除病房外,尚可用于家庭、野外、救护车等场所。

An LCD monitoring and analyzing system controlled by a type Intel 8031 MP(series MCS-51) for ECG is described. A type LM213 B liquid crystal display (LCD) has been used developed for the display of numbers, alphabets, graphs, etc. With its small size, light weight, low power consumption and easy handling, the LCD has been used as a display component for the portable ECG monitor. To enable the LCD to plot, it is connected with an 8-bit single-chip microcomputer and a system managerial program of 8k byte in assemble language is written. The RAM data can then be displayed in correspondence with the matrix-dot of LCD and the waveform data such as ECG, the respiratory wave, arterio-sphygmogram and so on can be displayed. The storing, identifying, alarming and other functions are also available in this system.
