【摘要】 本文采用多通道扫描开关配合高精度测量显示仪器精密测量空间中多点温度,为获得更好的测量结果而对干扰噪声的特性进行研究,依据噪声特性实现噪声分离,最后利用不同方法分别进行消除,同时对温度测量中常用降噪方法进行深入分析,比较各种技术方法的特点优势,并讨论其适用的场合。最后依据噪声特性设计通道信号测量和噪声处理方案,实现仪表测量结果最优化。更多还原

【Abstract】 For the better result would be gained in the course of using multi-channel scanner and high accurate measure instrument to get multi-dot temperature of space,characteristic of noise interference will be studied.The noises which have different characteristic and come from different resource can be separated and eliminated by dif- ferent ways.At the same time the common methods of noise elimination in the temperature measurement is ad- vanced analyzed where the characteristics and predominance of them are compared and the suitable application of them are discussed.Finally,for the better measure result the project of multi-dot temperature measurement and noise elimination is designed.更多还原
