摘要
对传统的SDT(Swinging Door Trend)过程数据压缩算法进行算法分析与改进研究,并在此基础上提出了综合去异常值、简单滤波、自适应压缩偏移量与还原曲线平滑化的改进型SDT压缩算法。算法结构简单、计算速度快,以MATLAB为研究仿真工具,通过算法的移植已经成功地应用于工业实时数据库产品FD-RDB中,获得了良好的过程数据压缩质量与还原效果。对工业实时数据库的过程数据压缩算法的设计开发具有很好的参考意义。
Propose an improved SDT（Swinging Door Trend） compression algorithm integrated with the elimination of wild value,easy filtering,adaptive compression offset and curve smoothing,base on the study of traditional SDT algorithm.Due to simple internal structure arid short calculating periods based on the research platform of MATLAB,this improved algorithm has been successfully used in industrial real-time database product called FD-RDB,and performed well both in compression and decompression of application.
