This kind of energy data storage means comprises the following steps:
Step S10, storer carries out parameter initialization, distributes respectively the memory address of integral part and fraction part.
Step S11, the data in initialization decimal memory disc.
Step S12, judge whether the electric energy increment reaches 0.01 kilowatt hour.If, enter step S13, further judge whether to reach 1 kilowatt hour; If not, return to step S12.
Step S13, if the electric energy increment reaches 1 kilowatt hour, enter step S14, the storage integral part.Be specially: step S141, the integral part of power taking energy; Step S142, the corresponding storage address of power taking energy integer; Step S143, write electric energy in the storage address that described integer is corresponding.
If the electric energy increment does not reach 1 kilowatt hour, enter step S15, the storage fraction part.Be specially: step S151, by the integer of electric energy, search the first address of the memory address that the storage of electrical energy decimal is corresponding; Step S152, by decimal, 10 data of corresponding dish are read from storer; Step S153, find the trip point of described 10 data; Step S154, deposit described electric energy decimal in the storage address that described trip point is corresponding in.
In the present embodiment, single-phase electronic energy meter is when normal operation, and the metering module of electric energy meter can be measured electric energy, when electric energy reaches 0.01kwh, carries out the power storage processing.During power storage, first by the bit data of energy data integer, calculate now address area corresponding to power storage, by the data reading in 10 addresses of this address area, find the trip point of data in these 10 addresses again, the data change of trip point is the little logarithmic data of electric energy, 10 data (being 1 data disks) after change are deposited in the corresponding address district, realized the storage of 0.01kwh electric energy, when electric energy runs to 1kwh, electric energy integer corresponding data has been deposited in assigned address.
Power on and the error correction process flow diagram of energy data storage means as shown in Figure 4.During power on, check fraction part after first checking the integral part data, search the fraction part data disks by integral part, by each data disks, only have the continuity rule before and after a trip point and saltus step data, find out the point of error in data and by its correction.Ten data in each decimal dish are initialized as: 00,91,92,93,94,95,96,97,98,99.
Be specially: step S161 starts power on.
Step S162 reads the electric energy integer from storer.
Step S163, judge that whether the electric energy integer is legal, if legal, enters step S164, by the integer of electric energy, searches the first address of the memory address of storage of electrical energy decimal respective disc; Step S165, by decimal, 10 data of corresponding dish are read from storer; Step S166, find the trip point in these 10 data.Step S167, determine whether 1 trip point, if enter step S168, determines that the previous data of saltus step are the actual power decimal.If not 1 trip point, in step S169, determines whether 2 trip points.
If in step S169, be two trip points, carry out step S170, judge whether first trip point front and back are continuous, if in step S171, correct first data; In step S172, determine second the previous data bit actual power of trip point decimal.
