移动式生物信号检测装置 设计方案 基于MSP430单片机的生物信号检测系统 学 校：成都信息工程学院 队伍名称：EDA 零组 参赛队员：余海 曾锐 王发修 指导教师：姚振东 摘 要 本生物信号检测系统以超低功耗的MSP430单片机为中央处理单元，以MCS-51单片机作为上位机，将收到从机的信息加以显示与判断。通过LCD液晶屏显示所测数据的波形，特征。 软件系统部分主要以下： 本系统利用开发工具进行编程开发，。这些工具的使用，使得软件的设计编程和调试工作得到了保证。 关键字： Abstract The biological signal detection system to ultra-low power MSP430 MCU to the central processing unit to MCS-51 SCM as a PC, will receive the information from the machine to be displayed with the judgement. Through the LCD screen shows the measured data waveform, characteristics. Some of the major hardware used on the weak telecommunications, biotechnology, such as cardiac, respiratory value, body temperature, blood pressure, such as signal amplification, filtering, to interference, such as acquisition. Harmonic filters do, the frequency signals so that more accurate measurement to the information needed by a system. The power of choice is a long time to work the radio lithium batteries. PC is primarily a data analysis and show that the major hardware for wireless data receiving and LCD module circuit. Some of the major software systems, including the following steps: 1, data acquisition machine: (that is, under the crew) to enlarge the weak signal filtering ? ? ADC to interfere with the conversion, MSP430 the ADC from the collection of data; 2, data storage (SCM crew internal RAM, temporary) 3, transfer of data / launch (FSK modulation radio transceiver module) 4, data processor: (PC) data reception and processing, according to stack one after another into the store, Duchushuoju, data processing and do shows and basic medical analysis. The system of development tools Keil 51 and IAR-MSP430 development program, through the serial port and ISP way replication procedures. The use of these tools, the software makes programming and debugging the design work was guaranteed. Keyword: mobile, biological signals, detection systems, data to the depositors, PC, the next cr
