Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but be merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
Existing IR46 electric energy meter is when carrying out electricity data storage, it is desirable that the trackability of continuous data needs full
At least one minute primary frequency of foot stores 1 year important electricity data.In normal conditions, it generallys use and freezes per minute
Once, its significant data is stored by fixed length mode, i.e., required per minute freeze-off time (5 byte) and high-precision is active
The data such as positive electricity (5 byte) and the active reversed electricity (5 byte) of high-precision store primary.
Then, when using conventional fixed length storage mode, i.e., the electricity number of 15 bytes of storage at least one minute
According to, it is known that, minute storage each time once accounts for 15 bytes, * when space gross space=15 byte * 366 days * 24 of storage in 1 year
60 points=7905600 bytes.
According to above-mentioned energy data storage mode, electricity storage freeze-off time include year, month, day, when and point, therefore
Within on the same day only point and when in lasting variation and the value of date does not change.In addition, according to actual electricity data
It is found that the electric energy difference of previous minute and latter minute can't be too big.Therefore, for being all made of above-mentioned routine per minute
Fixed length storage mode, it will consume a large amount of space to store and will not change too big electricity in the short time, i.e., excessive is superfluous
Balance storage can waste a large amount of memory space, and correspondingly, the cost of product can also be increase accordingly.
Then, the present invention proposes a kind of electricity data processing method of IR46 electric energy meter, by choosing benchmark electricity and remembering
Electric energy increment for benchmark electricity is used videotape to record to carry out the storage of electricity data, is also stored using random length mode, relative to
Conventional fixed length storage mode can effectively avoid the storage of bulk redundancy electricity data, and then save memory space.It ties below
Closing specific embodiment, the present invention is described in detail.
Embodiment 1
Fig. 1 is please referred to, the present invention proposes a kind of electricity data processing method of IR46 electric energy meter, by using random length
Mode stores 1 year important electricity data, can not only meet the IR46 electric energy meter to the trackability of electricity data, may be used also
To reduce the storage of bulk redundancy electricity data, and then reduce required memory space.Below to the electricity data processing method
It is described in detail.
In the present embodiment, the electricity data of the IR46 electric energy meter is primary every prefixed time interval storage, as shown in Figure 1,
The electricity data processing method can comprise the following steps that
Step S100, using the electricity of the initial time of each preset period of time as benchmark electricity, every preset time
The electric energy increment of electricity of the interval acquiring relative to the benchmark electricity or relative to the previous record moment, and to the electric energy
Increment is encoded by preset data form to obtain electric energy incremental encoding value.
Since IR46 electric energy meter needs to carry out 1 year electricity data at least one minute primary demand of storage, this reality
It applies in example, by presetting a time interval, i.e., every the prefixed time interval, electric energy meter just stores an electricity data.
It is appreciated that the prefixed time interval should be no more than 1 minute, for example, it may be storage in every 1 minute is primary, it is also possible to every
It is inferior that one is stored every 30 seconds or every 20 seconds.Preferably, which is 1 minute.
In view of the value for freezing the date of storage in one day will not all change, and previous minute and latter minute
Actual power is not much different, and in the present embodiment, will be deposited with carrying out electricity data by the way of benchmark electricity and electric energy increment
Storage.Specifically, a period of time can be preset to be then each time cycle for dividing to one day duration
Select an initial time.Then, using the electricity of the initial time of each time cycle as benchmark electricity, then every one
Time interval just obtains the electric energy increment of the once electricity relative to the benchmark electricity or relative to the previous record moment.
In the present embodiment, the benchmark electricity of initial time will stop code mode using electricity and store.For convenience by its turn
It changes high precision electro energy into, further, electricity can be stopped to the corresponding umber of pulse of code according to the side for carrying out 5 byte high precision electros energy
Formula is stored.
Preferably, above-mentioned preset period of time is 1 hour, i.e., can be divided into 24 time cycles within one day.It is found that one
A preset period of time when it is 60 minutes a length of.If prefixed time interval is 1 minute, need to deposit within each time cycle
Store up 60 electricity datas.
Preferably, the initial time of each preset period of time can be set as the zero moment.Exemplarily, with above-mentioned
One time cycle is the electricity of the initial time of each preset period of time for 1 hour, as hourly zero
Corresponding electricity is carved in timesharing.Then, it using the electricity at the zero moment as benchmark electricity, is then just deposited every a time interval
Storage is once relative to the electric energy increment of the benchmark electricity.
Certainly, the above-mentioned electric energy increment every time interval storage is also possible to remember relative to previous interval
The increment of the electricity of record.In view of calculating time etc. to save when tracing the practical electricity of a certain given time, it is preferable that
Each electric energy increment is the increment of the electricity relative to initial time.
Still optionally further, the electric energy increment got every time is encoded according to preset data form to obtain electricity
It can incremental encoding value.Wherein, which can be corresponding low-frequency pulse number.It exemplarily, can be according to two bytes 16
System (i.e. Hex format) encodes the corresponding umber of pulse of electric energy increment.
It should be appreciated that the preset data form should be not limited to the Hex format using two bytes, it can also be according to electricity
The concrete specification model of energy table encodes the electric energy increment using other byte numbers and extended formatting.By to each electricity
It can be worth and carry out incremental encoding storage, the byte length of its storage can be reduced, to be further reduced memory space.
Step S110 stores the initial time and the corresponding benchmark electricity according to the first preset format, according to the
Two preset formats successively store each record moment and the corresponding electric energy incremental encoding value after the initial time.
In the present embodiment, the practical electricity obtained each time is divided into two parts, i.e. benchmark electricity part and electric energy increment
Part.For benchmark electricity part, according to the first preset format can store the initial time and correspondence of each time cycle
Benchmark electricity.For electric energy incremental portion, each note after each initial time can be successively stored according to the second preset format
Record moment and corresponding electric energy increment, i.e., after having stored the electric energy increment at a upper record moment, the electricity at next record moment
Can increment and then the storage location at a record moment stores backward on this.
Exemplarily, when prefixed time interval is 1 minute, the zero moment that initial time is each hour, then this is first
When moment beginning can be the date, and each record moment can be point.
Optionally, which may include the first byte length, and the second preset format may include the second byte
Length, wherein the second byte length is smaller than the first byte length.
Exemplarily, which can be used 14 byte lengths to store the data of the benchmark electricity part,
Shown in table 1 specific as follows.And 5 bytes can be used to store the data of the electric energy incremental portion, such as following table in the second preset format
Shown in 2.It is found that when electricity data when storing each small using above-mentioned byte length, in addition to this hour zero when
The benchmark electricity at quarter needs 14 byte lengths, and every 1 minute energy data then only needs 5 bytes to store.
Table 1
Table 2
It is appreciated that it is a large amount of not have to waste using such non-fixed length storage mode compared with conventional fixed length storage mode
Memory space store redundant data, can save carrying cost etc..
In the present embodiment, it is further preferred that each the electric energy increment that also will acquire is compared with preset increments threshold value
Compared with for judging whether current electric energy increment exception occurs.It optionally, will be previous if described be judged as that appearance is abnormal
Electric energy increment of the electric energy increment as the current record moment for recording the moment can be effectively prevented what being mutated occurred in electricity in this way
Abnormal conditions.
Exemplarily, energy in one hour can be calculated with the maximum current according to the practical maximum current specification of electric energy meter
1.5 times of the maximum power of metering are as above-mentioned preset increments threshold value, i.e. max threshold, then when being more than the setting value,
It is abnormal then to indicate that the electric energy increment occurs, therefore can be recorded by the electricity increment at previous record moment, while can also provide
Data exception warning and exception record etc., to facilitate subsequent data exception analysis etc..
In the present embodiment, due to storing all electricity datas using above-mentioned electric energy incremental mode and non-f format,
The electricity data that given time is obtained for convenience of inquiry, further, as shown in Fig. 2, this method can also include step
S120 establishes single-level address index for the storage address of the electricity data.
Wherein, single-level address index S1 may include a plurality of S1 index data, and every S1 index data may include with day
For the storage address of the benchmark electricity at zero minutes moment in the memory unit when storing date and the same day zero of unit.
Optionally, 6 bytes can be distributed for each S1 index data, respectively includes date and 3 bytes of 3 bytes
Daily zero when zero minutes moment corresponding benchmark electricity storage address.Exemplarily, if 1 year over 366 days to calculate,
It may include 366 S1 index datas that the single-level address, which indexes S1, shown in table 3 specific as follows.Wherein, when 366 S1 index numbers
After storage completely, then comes back to the 1st article of position and circuit sequentially storage.
Table 3
It is found that can quickly navigate to depositing for zero point moment of specific a certain day in 1 year by single-level address index
Storage space is set, and is successively stored further according to one day all storing data, thus according to given time when and minute then can be with
Corresponding benchmark electricity and corresponding electric energy increment are found, so as to the lookup of the convenient electricity data to some given time.
Preferably, to further speed up retrieval rate, which can also include step S130, be
The storage address of the single-level address index establishes two-level address index.Specifically, two-level address index S2 may include with the moon
The storage address of this month first S1 index data in S1 is indexed for the storage date of unit and the single-level address.
Optionally, each S2 index data that S2 can be indexed for two-level address distributes 5 bytes, respectively includes 2 bytes
Days and 3 bytes S1 index address.Since single-level address index S1 includes 366 S1 index datas, when using second level
When location indexes S2, i.e., the 1st S1 index data of this month of a single-level address index S1 is monthly stored in memory space
Storage address, then two-level address index S2 may include 12 S2 index datas, shown in table 4 specific as follows.Wherein, when 12
After S2 index datastore is full, then comes back to the 1st article of position and circuit sequentially storage.
Table 4
It is found that can quickly navigate to the first S1 index data of the correspondence moon of given time by two-level address index
Storage location in single-level address index.Then, according to the day of given time it is known that when the given time is to corresponding to
The storage location of the electricity data at zero moment in the memory unit, and then specific electricity data can be got.
Exemplarily, when the reality for retrieving given time by above-mentioned single-level address index and two-level address index
When electricity, as shown in Figure 3, it may include following steps:
Step S200 searches corresponding single-level address index according to the days of given time in two-level address index
Storage address.Wherein, which is storage position of the first S1 index data of the corresponding moon in single-level address index
It sets.
Step S210 searches institute in single-level address index according to the level-one index data in the storage address
Storage address of the benchmark electricity at zero minutes moment in storage unit when stating the zero of the correspondence day of given time.Wherein, lead to
Cross the storage for reading the S1 index data electricity data at zero minutes moment that can get the given time in the zero of corresponding day
Address.
Step S220, according to the storage address and the given time of the benchmark electricity at zero minutes moment when described zero
When searched in the storage unit to it is corresponding when the zero moment benchmark electricity.In the present embodiment, carved at the beginning as per small
When the zero moment when, the electricity data at zero minutes moment when getting the zero of corresponding day, then further by it is specified when
Quarter when can find to it is corresponding when the zero moment benchmark electricity.
Step S230, according to the electric energy incremental encoding value of point lookup correspondence point of the given time, and according to institute
The benchmark electricity at zero moment when stating and the electric energy incremental encoding value calculate the practical electricity of the given time.Wherein,
When calculating practical electricity, first the electric energy incremental encoding value of acquisition is decoded, to obtain the pulse of corresponding electric energy increment
Number, then be added with benchmark electricity, so that the practical electricity of the given time be calculated.
In the present embodiment, it is preferable that all electricity datas will be stored in FLASH.Due to the write operation of FLASH
It has to first wipe and be written afterwards, it, can be at least when distributing memory space to guarantee quickly to store the electricity data of acquisition
The memory space of one sector of overabsorption.It is further preferred that can be advanced for when carrying out write-in each time to FLASH
One empty sector wiped, not only can be effectively avoided the address data with existing that FLASH is currently written into and causes to write again
There is mess code phenomenon when entering data, can also avoid starting to execute erasing operation again before preparing that data are written and cause need not
The waiting time etc. wanted.
Exemplarily, when storing each electricity data in FLASH, it is corresponding that the next record moment can be precalculated
Electricity data storage address in the memory unit.It specifically, can be according to the storage address of current electric quantity data and corresponding
Storing data format length calculates the storage address of next electricity data.Wherein, the storing data format is above-mentioned first
Preset format or the second preset format.
Exemplarily, if current memory address is 30H, and current electric quantity data are preset using the first of 14 byte lengths
Format storage, then the storage address at next record moment is 44H.Then, the electricity data at next record moment will be single from storage
Start to be written at the address 44H of member.
Further, if the storage address of the electricity data at next record moment be more than the memory allocation most
Big address, then the electricity data at the next record moment will subtract the corresponding position of storage address obtained after the maximum address
Write-in.
In the present embodiment, the process for advancing for the empty sector that one has been wiped includes: by storing FLASH
The maximum address and single sector space size of space distribution carry out logic and operation with obtain sevtor address calculate because
Son, wherein it is corresponding in FLASH that the sevtor address calculating factor can be used for calculating any one storage address in FLASH
Sector-start-address.If sector-start-address and the electricity data at next record moment where current FLASH storage address
Storage address where sector-start-address it is inconsistent, then it represents that the two storage address not in same sector, at this time will wipe
Except the sector where the storage address of the electricity data at next record moment, to advance for the empty sector wiped.
Exemplarily, if a FLASH memory space is 4M byte, i.e., the maximum address of corresponding distribution is 0x3fffff, and
Sector-size is 4K byte (i.e. 0x1000), then sevtor address calculates the factor=0x3fffff&0x1000=0x3ff000.
Assuming that current FLASH storage address is 0x0x23fe5, the storage address of the electricity data at next record moment is
0x24002, then by arriving current FLASH storage address with sevtor address calculating factor progress logic and operation
Sector-start-address=0x23fe5&0x3ff000=0x23000 where current FLASH storage address；And when next record
Sector-start-address=0x24002&0x3ff000=0x24000 where the storage address of the electricity data at quarter, it is known that, two
Sector-start-address where person is unequal, indicates not in same sector, at this time after having stored the electricity data of current record
Sector where the storage address for the electricity data that the next record moment can be wiped in advance.
It is appreciated that the time required for being wiped due to FLASH is relatively long, if waiting when being stored each time again
