Abstract:In order to improve the data block compression effect of grating sensor networkꎬ a lossless data block compres ̄ sion method based on LZW algorithm was designed for high load grating sensor network. Based on the construction of the storage structure modelꎬ the associated spectrum feature quantity of the data of the high-load grating sensor network was extracted. After the data block fusion processingꎬ the data block windowing processing was realized combining the parame ̄ ter multi-resolution reconstruction methodꎬ and the feature compression subspace scheduling model was constructed ac ̄ cording to the window function detection resultsꎻ Multi-scale LZW algorithm is used to realize feature decomposition and block compression of high load grating sensor network data in balanced Windows. The simulation results show that the pro ̄ posed method has strong ability of block fusion and matchingꎬ and can effectively improve the storage space of data.
