摘要
由于计算机测控系统处于在工业现场,其采集数据往往受到不同程度的干扰,在使用之前需要进行数据预处理。文中根据采集数据的种类和功用,系统地介绍了常用数据预处理方法,进行了相应的原理介绍,并讨论了这些预处理方法适用情况。
Due to the computer measurement and control systems located in industrial field, the sampled data often is disturbed in various degree, the data preprocess is needed before used it. In this paper, frequently-used data preprocess methods and relevant principle were introduced , according to the types and functions of sampled data, at the same time, the suitable application of the technology of data preproeess were discussed.
