为使医护人员在不接触患者的条件下,能对患者的身体状况进行实时地监护与诊治,研制一种基于无线通信的多信号实时采集与分析交互式系统。其主要由下位机和上位机组成。下位机是以PIC16F877A单片机为核心构建的信号采集和传输子系统,用于检测、滤波、采集、处理和无线传输多路信号。上位机是以PC机为核心构建的基于Lab VIEW和MATLAB软件的信号实时采集和分析子系统,用于接收、处理、分析、存储和显示多路信号。该系统可实现多路生物医学信号和环境信号的交互式无线采集、实时处理和分析显示。方便实时采集和分析被监测者的生理信号及其所处环境的相关信号,时刻掌握被监测者身体状态及环境状况。该系统的研制对医疗器械的发展具有一定的推动作用。
In order to enable medical staff to monitor and diagnose the patient’s physical condition in real time without touching the patient, a multi-signal real-time acquisition and analysis interactive system based on wireless communication is developed. Its mainly by the next crew and PC. The lower computer is a signal acquisition and transmission subsystem based on the PIC16F877A microcontroller, which is used to detect, filter, collect, process and wirelessly transmit multiple signals. The host computer is a real-time signal acquisition and analysis subsystem based on LabVIEW and MATLAB software which is built on the PC, which is used to receive, process, analyze, store and display multiple signals. The system enables interactive wireless acquisition of multiple biomedical and environmental signals, real-time processing and analysis displays. Convenient real-time acquisition and analysis of the monitored physiological signals and their environment-related signals, keep track of the monitored body condition and environmental conditions. The development of the system of medical equipment has a certain role in promoting.
