Fig. 3 is a schematic flow chart of a data storage method according to an embodiment of the present invention. It should be noted that, the data storage method provided in the embodiment of the present invention is not limited by fig. 3 and the following specific sequence, and it should be understood that, in other embodiments, the sequence of some steps in the data storage method provided in the embodiment of the present invention may be interchanged according to actual needs, or some steps in the data storage method may also be omitted or deleted. The data storage method can be applied to the electronic device 100 shown in fig. 1, and the specific flow shown in fig. 3 will be described in detail below.
Step S101, when the obtained electric meter data belongs to a first type of data, selecting a first preset number of idle storage units from a plurality of storage units according to the sequence of the storage addresses from low to high, and storing the electric meter data in the first preset number of idle storage units.
Step S102, when the obtained electric meter data belongs to second type data, selecting a second preset number of idle storage units from the plurality of storage units according to the sequence of the storage addresses from high to low, and storing the electric meter data in the second preset number of idle storage units; the number of the storage units occupied by the first type data and the second type data is different.
In this embodiment, the first type data may be meter data of the single-phase meter 200, and may be meter data of the three-phase meter 300. The second type data may be the meter data of the single-phase meter 200, and may be the meter data of the three-phase meter 300.
When the number of the storage units occupied by the first type of data is less than the number of the storage units occupied by the second type of data, the first type of data is the electric meter data of the single-phase electric meter 200, and the second type of data is the electric meter data of the three-phase electric meter 300. When the number of the storage units occupied by the first type of data is greater than the number of the storage units occupied by the second type of data, the first type of data is the electric meter data of the three-phase electric meter 300, and the second type of data is the electric meter data of the single-phase electric meter 200.
The first type of data is the meter data of the single-phase meter 200, and the second type of data is the meter data of the three-phase meter 300. When the number of the storage units occupied by the first type of data is less than the number of the storage units occupied by the second type of data, the number of the idle storage units in the first preset number may be one, the number of the idle storage units in the second preset number may be five, and the storage addresses of the idle storage units in the second preset number are continuous. When receiving the electric meter data, the electronic device 100 determines whether the electric meter data is the electric meter data of the single-phase electric meter 200 or the three-phase electric meter 300 according to the size of the electric meter data. If the received electric meter data is judged to be the electric meter data of the single-phase electric meter 200, one storage unit with the lowest storage address is selected from the idle storage units to store the electric meter data of the single-phase electric meter 200. If the received electric meter data is judged to be the electric meter data of the three-phase electric meter 300, and the number of the idle storage units with continuous storage addresses in the plurality of storage units is more than or equal to five, the five storage units with continuous storage addresses from high to low are selected from the idle storage units to store the electric meter data of the three-phase electric meter 300.
When the number of free storage units with continuous storage addresses, which are selected from the plurality of storage units in the sequence from high storage addresses to low storage addresses, is smaller than a second preset number, if the storage units are free and have storage addresses lower than the free storage units with continuous storage addresses, the electric meter data which are stored in the storage units adjacent to the free storage units with continuous storage addresses and belong to the first type of data are shifted to the storage units with the free storage addresses and the lowest storage addresses until the number of the free storage units with continuous storage addresses is equal to the second preset number.
It can be understood that if the memory 110 includes 1450 memory cells, each memory cell is correspondingly configured to have a memory address of 1-1450, the meter data of one single-phase meter 200 occupies one memory cell, and the meter data of one three-phase meter 300 occupies five memory cells with consecutive memory addresses. If only the memory cells corresponding to the memory addresses 2, 4, 7, 8, and 9 in the memory 110 are free, the meter data of the two single-phase meters 200 are stored in the memory cells corresponding to the memory addresses 5 and 6, and the meter data of one three-phase meter 300 is stored in the memory cells corresponding to the memory addresses 10-14, if the electronic device 100 receives the meter data of the three-phase meter 300 at this time, because the memory addresses of the free five memory cells are not continuous, the electronic device 100 cannot directly store the meter data of the three-phase meter 300 in the memory cells corresponding to the memory addresses 2, 4, 7, 8, and 9, the electronic device 100 will first shift the meter data of the single-phase meter 200 in the memory cell with the memory address 6 to the memory cell with the memory address 2, and then shift the meter data of the single-phase meter 200 in the memory cell with the memory address 5 to the memory cell with the memory address 4, after obtaining five free memory cells with the memory addresses of 5-9, the electronic device 100 stores the meter data of the three-phase electric meter 300 in the memory cells with the memory addresses of 5-9. In other words, the memory cells with the memory addresses of 7, 8, and 9 can be understood as the aforementioned idle memory cells with the number less than the second preset number and with consecutive memory addresses; the memory cells having the memory addresses 2 and 4 can be understood as the aforementioned memory cells which are free and have memory addresses lower than the free memory cells having consecutive memory addresses; the memory cell having the memory address of 6 may be understood as a memory cell adjacent to the aforementioned free memory cell having the memory address consecutive thereto and storing the meter data of the single-phase meter 200.
The idle storage units with storage addresses lower than the storage addresses continuously may be always in an idle state, or the electronic device 100 may delete the idle single-phase electric meter 200 in the storage units with storage addresses lower than the storage addresses continuously in response to a deletion operation of a user, so as to obtain the idle storage units with storage addresses lower than the storage addresses continuously.
The first type of data is the meter data of the three-phase meter 300, and the second type of data is the meter data of the single-phase meter 200. When the number of the storage units occupied by the first type of data is greater than the number of the storage units occupied by the second type of data, the first preset number of idle storage units may be five, the second preset number of idle storage units may be one, and the storage addresses of the first preset number of idle storage units are continuous. When receiving the electric meter data, the electronic device 100 determines whether the electric meter data is the electric meter data of the single-phase electric meter 200 or the three-phase electric meter 300 according to the size of the electric meter data. If the received electric meter data is judged to be the electric meter data of the single-phase electric meter 200, the electric meter data of the single-phase electric meter 200 can be stored in the storage unit with the highest storage address selected from the idle storage units. If the received electric meter data is judged to be the electric meter data of the three-phase electric meter 300, and the number of the idle storage units with continuous storage addresses in the plurality of storage units is greater than or equal to five, the five storage units with continuous storage addresses from low to high are selected from the idle storage units to store the electric meter data of the three-phase electric meter 300.
When the number of idle storage units with continuous storage addresses, which are selected from the plurality of storage units according to the sequence of the storage addresses from low to high, is smaller than a second preset number, if the storage units which are idle and have the storage addresses higher than the idle storage units with continuous storage addresses exist, the ammeter data which are stored in the storage units adjacent to the idle storage units with continuous storage addresses and belong to the second type of data are shifted to the storage units with the idle and the highest storage addresses until the number of the idle storage units with continuous storage addresses is equal to the first preset number.
It can be understood that if the memory 110 includes 1450 memory cells, each memory cell is correspondingly configured to have a memory address of 1-1450, the meter data of one single-phase meter 200 occupies one memory cell, and the meter data of one three-phase meter 300 occupies five memory cells with consecutive memory addresses. If only the storage units corresponding to the storage addresses 6, 7, 8, 9, 12, and 14 in the memory 110 are free, the storage units corresponding to the storage addresses 10 and 11 store the meter data of the two single-phase meters 200, and the storage units corresponding to the storage addresses 1 to 5 store the meter data of one three-phase meter 300, at this time, if the electronic device 100 receives the meter data of the three-phase meter 300, because the storage addresses of the free six storage units are not continuous, the electronic device 100 cannot directly store the meter data of the three-phase meter 300 in the storage units corresponding to the storage addresses 6, 7, 8, 9, 12, and 14, the electronic device 100 will first shift the meter data of the single-phase meter 200 in the storage unit with the storage address 10 to the storage unit with the storage address 14, and obtain five free storage units with the storage addresses 6 to 10, the electronic apparatus 100 stores the meter data of the three-phase electric meter 300 in the memory location having the memory address of 6-10. In other words, the memory cells with the memory addresses of 6, 7, 8, and 9 can be understood as the aforementioned idle memory cells with consecutive memory addresses whose number is less than the first preset number; the memory cells with the memory addresses 12 and 14 can be understood as the memory cells with the free memory cells and the memory addresses higher than the free memory cells with continuous memory addresses; the memory cell having the memory address of 10 may be understood as a memory cell adjacent to the aforementioned free memory cell having the memory address consecutive thereto and storing the meter data of the single-phase meter 200.
The storage units of the idle storage units with the idle addresses higher than the continuous storage addresses may be always in an idle state, or the electronic device 100 may delete the idle single-phase electric meter 200 in the storage units of the idle storage units with the storage addresses higher than the continuous storage addresses in response to a deletion operation of a user, so as to obtain the storage units of the idle storage units with the idle addresses higher than the continuous storage addresses.
Further, as shown in fig. 4, which is another implementable flow diagram of the data storage method provided in the embodiment of the present invention, the data storage method shown in fig. 4 further includes the following steps on the basis of the data storage method shown in fig. 3:
and step S103, outputting first prompt information when the total number of the idle storage units is less than a second preset number.
In this embodiment, when the number of the storage units occupied by the first type of data is less than the number of the storage units occupied by the second type of data, the second preset number is greater than the first preset number. When the total number of the free storage units is less than the second preset number, which indicates that the storage space of the memory 110 is insufficient to store the meter data of one three-phase meter 300, the electronic device 100 may output a first prompt message indicating that the storage space is insufficient.
And step S104, outputting first prompt information when the total number of the idle storage units is less than a first preset number.
In this embodiment, when the number of the storage units occupied by the first type of data is greater than the number of the storage units occupied by the second type of data, the first preset number is greater than the second preset number. When the total number of the free storage units is less than the second preset number, which indicates that the storage space of the memory 110 is insufficient to store the meter data of one three-phase meter 300, the electronic device 100 may output a first prompt message indicating that the storage space is insufficient.
Further, as shown in fig. 5, which is a schematic flow chart of another implementable data storage method provided in the embodiment of the present invention, the data storage method shown in fig. 5 further includes the following steps based on the data storage method shown in fig. 3:
and step S105, outputting second prompt information when no idle storage unit exists.
In this embodiment, when there is no free storage unit, indicating that the storage space of the memory 110 is completely occupied, the electronic device 100 outputs the second prompt message that the storage space is full.
In order to perform the corresponding steps in the above embodiments and various possible manners, an implementation manner of the data storage device 140 is given below. Referring to fig. 6, fig. 6 is a schematic diagram illustrating functional modules of a data storage device 140 according to an embodiment of the present invention. It should be noted that the basic principle and the generated technical effect of the data storage device 140 provided in the present embodiment are the same as those of the above embodiments, and for the sake of brief description, no part of the present embodiment is mentioned, and corresponding contents in the above embodiments may be referred to. The data storage device 140 includes a first storage processing module 141, a second storage processing module 142, and an output module 143.
