Sensor data optimization acquisition and storage method

The invention relates to the technical field of data processing, in particular to a sensor data optimization acquisition and storage method, which comprises the following steps: acquiring historical temperature data and real-time temperature data; according to the occurrence frequency of any character in the character type range in the historical temperature data and the real-time temperature data, obtaining the influence of the frequency difference on the compression ratio of the Fischer coding algorithm, and obtaining new real-time temperature data; obtaining a reconstructed Fischer-Tropsch coding tree, and obtaining first coded data and second coded data according to the reconstructed Fischer-Tropsch coding tree and the Fischer-Tropsch coding tree; and storing the first coded data or the second coded data. According to the method, the Fischer coding tree is self-adaptively reconstructed, the real-time change condition of the data is better adapted, the overall compression effect of the data is further impr
