基于MSP430的远程无线体温测量系统

摘要

A remote wireless thermometer system is putted forward for the situation of measuring and recording body temperature by hand in the hospital.This system is composed of two core modules,i.e.,remote thermometer module and central receiver module,which both take MSP430 MCU as master control.The remote thermometer module utilizes TN9 sensor chip to measure body temperature and send the data by the nRF905 RF chip wireless.The central receiver module receives the data and transfers them to PC by RS232 to record the temperature automatically.After the practical test,it can be found that the system can be fast and accurate measurement,recording and management of body temperature.This system with low-power,low-cost and high-practicality has good promotional value.%针对目前医院临床监护中人工测量、记录病人体温的现状,提出一种远程无线体温测量系统的设计.该系统由远程体温测量模块和中心接收模块两大模块组成,以低功耗MSP430单片机为主控,远程测量块利用TN9红外温度传感器测量体温,并将数据通过nRF905射频芯片无线发送;数据由中心模块接受后通过RS232串口传给PC机,自动记录病人体温.经实际测试,该系统可以快速、准确的对病人体温进行测量、记录和管理,有低功耗、低成本、高实用性的特点,很有推广价值.
