高精度测温的混沌方法

Chaos Method for High Precision Temperature Measurement

基于混沌电路参数敏感性的温度测量方法具有精度高的特点,考虑到温度对电子元件的影响具有普遍性,测量时将所有温度敏感元件和传感器都置于同一被测环境中,这些元件除完成本身的功能外,也参与温度传感作用。在测温实验研究中,加入热敏电阻作为主要的感温元件,使测温精度进一步提高,说明该方法具有一定的发展潜力。

Temperature measurement method based on parameter sensitivity of chaotic circuit is characterized by higher precision.Considering the universality of temperature affecting electronic elements,all elements sensitized to temperature and sensor are put in the same environment.Besides their circuit functions,they all serve as sensors.In chaotic circuit experiment of temperature measurement using thermal resistance as main sensitive element,the accuracy is improved obviously.
