Quick query method for periodic frozen data of electric energy meter

The invention discloses a quick query method for periodic frozen data of an electric energy meter, and belongs to the field of electric digital data processing. The method comprises the following steps of: 1, finding two freezing points N1 and N2 which meet the following conditions from frozen data: a time mark TimerX to be queried is positioned between the N1 and the N2, and the time mark and the serial number of the frozen data between the N1 and the N2 are in a linear relationship; step 2, setting a time mark of a freezing point N1 as TimerN1 and a serial number as NoN1, setting a time mark of a freezing point N2 as TimerN2 and a serial number as NoN2, and obtaining a serial number NoX corresponding to TimerX according to a linear relation; and step 3, returning frozen data corresponding to the serial number NoX. The method solves the problem that an original query mode cannot deal with discontinuous increasing of time marks, and has the advantages of high query efficiency and the like. 本发明公开了一种电能表周期冻结数据的快
