Abstract

This application discloses a method for compressing and decompressing frozen electric quantity data of a smart meter, only needing to set key time point labels, adopting a difference method to avoid redundant storage of repeated data, and using carry data to process electric quantity data to further save It reduces the storage space and simplifies the complexity of the calculation process of decompression, thereby improving the reliability and search efficiency of data storage, and greatly reducing the space occupied by the data storage of electric energy meters, which solves the problem of freezing of electric energy meters in the existing storage Power data requires a large amount of storage space and access speed technical issues.

Description

technical field [0001] The present application relates to the technical field of smart meter data processing, in particular to a method for compressing and storing frozen power data of smart meters and a method for decompressing them. Background technique [0002] According to the R46 standard, when the energy meter needs to store data, the measurement data must be automatically stored when the measurement results (that is, when the final value has been generated). The storage device must have enough durability to ensure that the data will not be damaged in the daily storage environment, and the memory space should be sufficient to store any special application. [0003] For example, if the power bureau needs to track the electricity consumption information of a certain period of time, it needs the meter to be able to record the frozen data frequently at a certain time interval. The storage of these frozen data requires a large space. For the legally relevant parts of the sm...
