【摘要】 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。更多还原

【Abstract】 In order to make sure that doctors can diagnose and give treatment to the patients’ health state in real time under the condition of no contact with patients, a real-time interactive system of multi-signal acquisition and analysis based on bluetooth wireless technology has been developed. It consists of the hardware design and software design. The hardware is designed based on PIC16F877 A, which is used to detect, filter, collect, process and transmit multi-signals. The software is designed based on Lab VIEW and MATLAB, which is mainly used to receive, process, analyze, store and display multi signals. The system can realize wireless acquisition, processing and analysis of multichannel biomedical signals and the environment information. Moreover, it’s convenient to detect and monitor patients’ physiological signals and the relevant environment information, so the doctors can master patients’ health states timely. The development of the system plays an important role in promoting the development of medical devices.更多还原
