网络化电子体温测量系统的研制

摘要

目的：研制网络化电子体温测量系统.方法分析国内外体温测量工具的使用现状，研制由数字温度传感器DS18B20和微控制器 AT89S53两部件组成的体温测量系统.结果可以多人同时测量体温，并能够实现体温测量的网络化，测温分辨率达到0．0625℃.结论目前，大部分医院采用玻璃水银温度计测量体温，护理工作量大且存在水银中毒的危险，网络化电子体温测量系统是今后体温测量的发展趋势.%Objective To develop the networked new body temperature measuring system.Methods This paper analyzes the current application of body temperature measuring tool both in domestic and foreign countries,and develop the digital temperature sensor DS18B20 and micro controller AT89S53 temperature measuring system.Results Taking body temperature for multiple people at the same time is possible and can be networked,with a resolution of 0.0625℃.Conclusion At present,glass mercury thermometers are widely used in most hospitals which lead to heavy nursing workload and the risk of mercury poisoning.Net-working electronic body temperature measuring system is now becoming the new trend.
