Electric power tunnel water level data storage method and historical data estimation method

Abstract

The invention relates to the field of power cable online monitoring, in particular to a power tunnel water level data storage method and a historical data estimation method. The electric power tunnel water level data storage method comprises the following steps: 1) counting historical water level data of a water level detector; 2) segmenting the water level data to obtain a plurality of sub-data segments; 3) fitting each sub-data segment by using a set function to obtain a formula parameter of the set function; and 4) storing formula parameters and special data. According to the method, a large amount of redundant data is compressed, the storage efficiency is greatly improved, the problems of inquiry lagging and display lagging caused by a large storage amount are effectively solved, meanwhile, historical data can be accurately estimated, and the accuracy of the data is ensured.
