摘要
为准确掌握临床医疗与医学研究中的人体皮温并进一步进行数据分析,利用热敏电阻测温,通过单片机与上位机之间的串口通信,设计了以MSP430F149单片机为核心处理器、热敏电阻与放大器为测量电路、SMC1602为LCD(Liquid Crystal Display)显示器、单片机内部Flash为存储器的可存储式人体皮温测量仪。数据通过串口通信电路传输到上位机,完成数据的分析与处理。实验结果表明,该测量仪测量精度为0.1℃,存储器空间支持持续测量4天以上的皮温数据,能为临床医疗及医学研究提供更可靠的依据。
In order to improve the clinical medical and in medical research on human skin temperature accurately and further analyze the data, use thermistor for temperature measurement, use the single chip microcomputer to accomplish communication. Design the MSP430F149 MCU （Micro Control Unit） as the core processor. Thermistor and amplifier for measurement circuit. SMC1602 for LCD （Liquid Crystal Display） display. MCU internal Flash for memory storage type can human body skin temperature measuring instrument. The measuring instrument storage data through serial communication circuit transmission to epistatic machine. Complete data analysis and processing. The experiment showed that this measuring instrument measuring accuracy is 0.1 ~C. Memory space support continuous measuring four days above the skin temperature data. For clinical medical and medical research provide more reliable basis.
