呼吸传感器应用技术的关键是采集呼吸的信号并准确地在计算机中显示出来。本文就从呼吸传感器的原理出发，对测量系统中的各个部分分别介绍；论文的前两部分从温度的标定和温度传感器材料的选取，提出了把铂作为材料的根据；论文的中间部分分析了计算机接口和总括的测量系统，并对采集到的信号进行了分析；论文的最后从人机工程学的角度考虑了呼吸传感器的应用。 全文以温度传感器为主线，介绍了利用温度传感器测量呼吸频率的原理，并对实验得到的数据进行了分析。-respiratory sensor applications, the key is to breathe signal acquisition and accurately on computer displayed. This paper from the respiratory sensor based on the principles of the measurement system were introduced in various parts; The first two papers from a temperature sensor calibration and temperature materials selection, put forward the platinum material as the basis; The paper analyzes the middle part of the computer interface and the whole system of measurement, and Acquisition of the signal analysis; the final papers from the ergonomics point of view of the respiratory sensor applications. The full text of the temperature sensor to the main line, introduced to the use of temperature sensors measure respiratory frequency theory, the experimental data were analyzed.
