【Abstract】 A real-time data compression algorithm and data quick preview algorithm based on wavelet transform is proposed to solve the redundant problem and quickly display problems of data acquisition in dynamic environment control test. The classical Mallat decomposition and synthesis algorithm is improved so that it can be used in real-time transformation. According to the relationship between wavelet transform and function derivative, a method of fast extracting experimental data trends is presented, it can be used to quickly preview the whole process of dynamic test. The experimental results show that the algorithm has good effect on the compression and preview of the data in dynamic environment control test.更多还原
