The invention discloses an intelligent electric meter segmented freezing data storage method and device and an intelligent electric meter segmented freezing data query method and device. The method comprises the following steps: S1, reading a segmented freezing associated object attribute table, and establishing a scheme record table corresponding to each segmented freezing scheme according to thefreezing period, the storage depth and the associated OAD attribute characteristics of each associated object attribute; S2, according to the scheme record table, reading and storing the content andreading time of first segmented freezing data corresponding to the scheme record table in the electric meter, and; and S3, sequentially reading and storing other segmented freezing data of the schemeaccording to a preset period. According to the invention, the technical problem that in an existing scheme, the reading time data of each piece of segmented freezing data needs to be stored, and the occupied storage space is large is solved, the data expenditure is reduced, and the quantity of segmented freezing data capable of being stored is increased.
