【摘要】：体温是人体的一项重要生命体征,许多疾病往往会导致体温发生变化,对于体温的测量通常是判断人体状态的初步手段。春秋季节是流行病的高发季节,中小学和幼儿园的学生又是易感人群,学校人员密集,随着水银体温计的淘汰,红外体温计以其测温快速、准确、非接触的优点,得到了普遍的使用。本文设计了一款便携式的红外额式体温计,依据设计的电路原理图,使用Proteus可视化设计对红外体温测量进行仿真,然后制作PCB和实物。采用医疗专用的红外线传感器MLX90615,测温快速准确,采用锂电池,节能环保,并且设计充电管理和电压转换电路。采用单片机MSP430G2553,低功耗程序设计,配合三个独立按键,Mealy型状态机的编程方法实现不同功能,蜂鸣器对体温异常者报警。单片机将采集到的体温数据显示在OLED液晶屏上,同时通过蓝牙无线传输模块,发送到上位机。上位机在LabVIEW平台进行开发,通过建立数据库,实现对众多信息的管理。上位机主要包括用户登录系统和体温数据管理系统。体温数据管理系统中,能够将下位机发送来的数据进行显示、报警和存储。数据分析中,将保存的数据在XY图和表格中回放出来,找出此人体温的最大值、最小值,计算体温平均值,还具有数据打印和备份功能。最后,进行系统的联调,验证系统性能。
[Abstract]:Body temperature is an important vital sign of the human body, many diseases often lead to body temperature changes, temperature measurement is usually the preliminary means to judge the state of the human body. Spring and Autumn season is the high incidence of epidemic season, primary and secondary school and kindergarten students are susceptible people, school staff density, with the elimination of mercury thermometers, infrared thermometers with its rapid, accurate, non-contact advantages. It is widely used. In this paper, a portable infrared forehead thermometer is designed. According to the designed circuit schematic diagram, the infrared temperature measurement is simulated by using Proteus visual design, and then PCB and real object are made. The infrared sensor MLX90615, is used to measure the temperature quickly and accurately, the lithium battery is used to save energy and environmental protection, and the charge management and voltage conversion circuit is designed. The low power program design of single chip computer (MSP430G2553,) and three independent keys are adopted. The programming method of Mealy state machine realizes different functions. The buzzer alerts those with abnormal body temperature. The temperature data is displayed on the OLED LCD screen and transmitted to the upper computer by Bluetooth wireless transmission module. The host computer is developed on the LabVIEW platform, through the establishment of database, to achieve the management of a lot of information. Host computer mainly includes user login system and temperature data management system. In the temperature data management system, it can display, alarm and store the data sent by the lower computer. In data analysis, the saved data is replayed in the XY diagram and table to find out the maximum and minimum temperature of this person, to calculate the average body temperature, and also to print and backup the data. Finally, the system is combined to verify the performance of the system.
