Embodiment Construction
[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.
[0041] A preferred embodiment of the present invention relates to a method for compressing and storing multi-source time series data. The multi-source time series data comes from different measurement points of different deployment objects. The specific flow chart of the method is as follows figure 1 shown.
[0042] In step 101, each deployment object is grouped according to the number of measurement points contained in each deployment object. In this step, two or more deployment objects whose total number of measurement points is less than a preset value are divided into a group, and each remaining deployment object is divided into a group respectively.
[0043] For example, the default value is 20,000, deployment object 1 has 10,000 m...
