Present embodiments provide a kind of electric energy meter data storage implementation method in actual applications, first memory
EEPROM and second memory Flash.In wherein EEPROM can with the energy data in real-time storage the most every 1 minute,
The energy data of other times is all regularly saved in Flash.
Eeprom memory is described as follows：As a kind of concrete implementation mode, open up two in EEPROM and deposit
Storage area, i.e. the first memory block and the second memory block, can be used for storing the storage information of two days, alternately erasable using two memory blocks
Mode data storage.In electric energy meter normal work, at two memory spaces only, deposit data, another place is sky.Than
If, storage information (i.e. information to be deposited) is in the first memory block, when the first memory block storage in EEPROM full 1 day of quantity of information (i.e.
First Preset Time is set to 1 day) when, this storage information is write in Flash, the storage letter in simultaneously erased first memory block
Breath, the information to be deposited (being the information to be stored of first minute point of next day) that electric energy meter got in next minute can deposit to
Second memory block, so, is realized two memory blocks and is carried out information Store in the way of rotation.Wherein, press storage information in Flash
The storage of markers sequential loop, when data storage amount full 1 year (i.e. the second Preset Time is 1 year), will cover earliest one day
Data, by that analogy.

S401：Ammeter trigger data per minute storage action, after current ammeter clock is organized with the data that need to store
Put into temporal cache；
S402：Read the data of memory block at two, judge whether its markers is all effective, if entering step S403, S404,
Otherwise enter step S411；
S403：Then compare temporal cache data markers whether more than two in memory block (the such as first memory block) larger
When the target date, judgement be enter step S405, otherwise enter step S408；
S404：Using the less valid data of markers in memory block at two as treating unloading data, subsequently into step S406；
S405：Using this temporal cache data as treating unloading data；
S406：Relatively treat whether the markers of unloading data is more than the markers of a nearest day data in Flash, if entering step
Rapid S407, otherwise terminates；
S407：By data conversion storage effective in EEPROM to Flash, subsequently into step S410；
S408：If target date when temporal cache data markers is not more than larger in memory block at two, judge interim
On target date when whether data cached markers is equal to larger in memory block at two, judgement is to enter step S409, otherwise terminates；
S409：Judge the time-division offset address of time-division in the markers of temporal cache canned data in corresponding EEPROM backward
The data of (including this point) whether void in whole, if entering step S410, otherwise terminates；
S410：Temporal cache data is write EEPROM；
S411：Judging whether the data in memory block at two has at one effectively, if entering step S403, otherwise entering step
Rapid S412；
S412：Data in temporal cache is stored in memory block at wherein the one of EEPROM；
The electric energy meter data storage that the present embodiment provides implementation method in actual applications, is adopted by first memory
EEPROM carries out real-time storage, second memory is timed storage using Flash flash memory, effectively avoids in prior art
EEPROM memory capacity is little, Flash flash memory wiping/writing number of times is low and the shortcoming of erasable time length, is preserving the same of Large Volume Data
