1、關鍵詞：旋轉門（SDT）；流程工業(yè)；數(shù)據(jù)Abstract: Process industry time-series data storage based on Swinging door compression lgorithm is applied in industrial production of common data compression storage model, based on the Swinging door compression algorithm can well improve the efficiency of data compression and s

2、torage precision. Swinging door algorithm is a relatively fast linear fitting method, often used in real-time database data compression, reduce storage capacity greatly. Swinging door algorithm as a simple linear fitting algorithm, and has high efficiency, high compression ratio, the advantages of s

3、imple implementation, error can be controlled, has now become a specialized algorithm. Data storage based on Swinging door compression algorithm has great prospects for development.Keywords:Swingingdoor(SDT);Processindustries;Data旋轉門壓縮算法、基于斜率比較的旋轉門壓縮算法和死區(qū)限值壓縮算法1-3，其中較流行的是旋轉門壓縮算法4，該算法是通過減少存儲數(shù)值的數(shù)量來實現(xiàn)壓
