| Abstract: | The preprocessing technology of raw data is very important for the process control system. The article introduces kinds of preprocess technology. Taking the calciner temperature sampling data in Lithopone kiln and calciner control system as an example, the passage analyzes the problems occurred in sampling such as singularity value, wave, sampling default and etc. The article discusses detailedly such technology as singularity detecting and compensating, default detecting, data smoothing and filtering, which has had good effects on calciner temperature data preprocessing. |
