Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention discloses a storage method for an electric energy meter, which is shown in fig. 1 and comprises the following steps:
S11: when the electric energy data are acquired in the first unit time, the electric parameters are stored in a preset storage position.
Specifically, the first unit time is a fixed duration, and the duration is determined by the data update period. The electric energy data comprises acquisition parameters and electric parameters, wherein the acquisition parameters comprise a first timestamp and a storage sequence number corresponding to a first unit time. The electric parameter is a common electric parameter.
For example, if the data update period of the power data is one minute, the first unit time is one minute; if the data update period of the power data is five minutes, the first unit time is 5 minutes.
Illustratively, taking a data update period as an example of one minute, after one piece of power data is acquired within one minute, the one piece of power data is read. The electric energy data comprises acquisition parameters and electric parameters, wherein the acquisition parameters comprise a time stamp (namely a first time stamp) and a storage sequence number, the time stamp is the acquisition time corresponding to the current electric energy data, and the storage sequence number is the current electric energy meter, and the electric energy meter updates the number of data from the beginning of being put into use. The electric parameters comprise data such as electric energy, electric power and the like corresponding to the first time stamp. When the electric energy data are acquired in the first unit time, the electric parameters are stored in a preset storage position, and the preset storage position is specially used for storing all the electric parameters updated in each unit time in a certain time period.
S12: when the first unit time is determined to be the first unit time in the period to which the first unit time belongs according to the first timestamp, a storage address corresponding to the electric parameter at a preset storage position is acquired.
Specifically, the period includes a plurality of unit times, and the first unit time is any one of the plurality of unit times. The period herein refers to a storage period of data.
Illustratively, in the present embodiment, the unit time is one minute and the period is one day, and 1440 units of time are included in one period, i.e., one day. When one piece of electric energy data is obtained, a time stamp (namely a first time stamp) corresponding to the piece of electric energy data is read. Assuming that the time stamp is 2022/12/13/0:00, when the unit time of the time stamp is the first unit time in the belonging period (2022/12/13 day), the storage address corresponding to the electric parameter corresponding to the time stamp in the preset storage position is acquired.
S13: nodes are added in the pre-constructed linked list, and the same number of state bits as the unit time in the period are configured in the nodes.
Specifically, when the unit time corresponding to the time stamp of the obtained electric energy data is the first unit time in the belonging period, a node is added in the pre-constructed linked list, and the newly added node is configured with the same number of state bits as the unit time contained in the one period, and the state information on the state bits is used for indicating whether the electric parameters exist in the unit time corresponding to the state bits.
For example, in the above embodiment, the time stamp of the obtained electric energy data is 2022/12/13/0:00, that is, the unit time corresponding to the time stamp is the first unit time in the period of the corresponding electric energy data can be determined, then a node is newly added in the constructed linked list, 1440 status bits are configured in the node, and the initial status information is configured on each status bit, and the initial status information can be configured to be 0. The state information on the state bit is used for indicating the existence state of the electric energy data in the unit time corresponding to the state bit, the initial state information indicates that the electric energy data does not exist in the unit time corresponding to the state bit, and when the electric energy data exists in the unit time corresponding to the state bit, the initial state information needs to be modified.
S14: a first timestamp, a storage sequence number, and a storage address are stored in the node.
Specifically, when the unit time corresponding to the obtained timestamp of the electric energy data is the first unit time in the period, the first timestamp, the storage sequence number and the storage address are stored in the node.
S15: the initial state information of the state bit corresponding to the first unit time is updated to be preset state information, and the storage address is set as the head address of the node.
Illustratively, after storing the first timestamp, the storage sequence number, and the storage address in the node, the initial state information 0 on the state bit corresponding to the first unit time needs to be updated to the preset state information 1. Wherein 0 indicates that no electrical parameter exists in unit time, and 1 indicates that an electrical parameter exists in unit time. The change of the state information of the state bit is convenient for the follow-up when searching the electric parameter corresponding to a certain moment, the existence state of the electric parameter can be determined according to the state information on the state bit corresponding to the moment, and then whether the corresponding data need to be searched further or not is judged according to the existence state of the electric parameter.
S16: or when the first unit time is determined not to be the first unit time in the period to which the first unit time belongs according to the first time stamp, searching the node corresponding to the period from the linked list based on the first time stamp.
For example, assuming that the time stamp in the electric energy data acquired in this embodiment is 2022/12/13/8:35, it may be determined based on the time stamp that the first unit time corresponding to the time stamp is not the first unit time in the period to which the unit time belongs, and at this time, it is necessary to first search, based on the time stamp, a node corresponding to the period to which the unit time belongs from the pre-constructed linked list.
S17: when the node exists, the initial state information of the state bit corresponding to the first time stamp in the node is updated to be preset state information.
Specifically, when the node exists in the linked list, a state bit corresponding to the unit time of the timestamp is found in the state bit of the node, and the initial state information on the state bit is updated to be the client case number
And presetting state information.
After acquiring one piece of electric energy data, the invention stores the data content in the electric energy data in two parts, stores the electric parameters in a preset storage position and stores the acquisition parameters in the nodes of the linked list. Because the acquisition parameters among the electric energy data are regularly and circularly available, the acquisition parameters and the storage positions corresponding to the electric energy data acquired in the residual unit time can be deduced according to the rules only by storing the acquisition parameters corresponding to the first unit time in one period and the storage addresses of the electric parameters in one node. For example, one piece of electric energy data occupies 15 bytes in total, wherein the time stamp occupies 7 bytes, the storage sequence number occupies 4 bytes, and the electric parameter occupies 4 bytes. If the existing storage mode is adopted, the storage of 8 pieces of electric energy data requires 120 bytes of space. If the storage method provided by the scheme is adopted, 8 pieces of electric energy data are stored in two parts, (1) the first part is that the electric parameter parts of the 8 pieces of electric energy data are stored in preset storage positions, 4 bytes are occupied by the electric parameter in each piece of electric energy data, and then 32 bytes are occupied by the 8 electric parameters corresponding to the 8 pieces of electric energy data in total. (2) The second part is to store the acquisition parameter part of the first electric energy data in the 8 electric energy data in the pre-constructed linked list nodes, wherein the acquisition parameter of the first electric energy data occupies 11 bytes. Meanwhile, the node also stores 8 state bits corresponding to the storage address of the first electric parameter at the preset storage position and 8 electric energy data, the storage address occupies 4 bytes, each state bit occupies 1 bit, and 8 state bits correspond to 8 bits, namely 1 byte. Therefore, by adopting the storage method provided by the scheme, the space for storing 8 pieces of electric energy data is as follows: 32+11+4+1=48 bytes. Compared with 120 bytes occupied by the existing storage mode, the storage method provided by the invention can greatly reduce the space occupied by data, and the effect is particularly obvious when the data volume is increased.
In an alternative embodiment, after adding nodes in the pre-constructed linked list and configuring the same number of status bits as the unit time in the period in the nodes, the method further includes:
and establishing a mapping relation between the second time stamp of the first piece of data in the period and the node.
Illustratively, the first data in a cycle refers to the power data acquired in the first unit of time in the cycle. After the same number of status bits as the number of unit times in the period are configured in the node, a second timestamp corresponding to the first piece of data may be used as an initial timestamp of the node.
In an alternative embodiment, when it is determined according to the first timestamp that the first unit time is not the first unit time in the period to which the first unit time belongs, searching for a node corresponding to the period from the linked list based on the first timestamp includes:
Judging the period of the first unit time corresponding to the first time stamp based on the first time stamp; determining a second timestamp of the first piece of data in the period; searching the node corresponding to the second timestamp from the linked list according to the mapping relation between the second timestamp and the node; when the node exists, the node is taken as the node corresponding to the period to which the first unit time belongs.
Illustratively, in the present embodiment, the unit time is one minute and the period is one day. When the first time stamp corresponding to the obtained piece of electric energy data is 2022/12/13/8:35, since the unit time corresponding to the first time stamp is not the first unit time in one day, at this time, the period to which the unit time corresponding to the first time stamp belongs may be determined according to the first time stamp 2022/12/13/8:35, that is, 2022/12/13. Then, according to the judged period, determining that the second timestamp of the first piece of data in the period is 2022/12/13/0:00. from the mapping relationship between the second timestamp and the node, it can be known that the second timestamp 2022/12/13/0:00 is the initial timestamp of the node. Finally, the second timestamp may be used as an index, and the initial timestamp is 2022/12/13/0 from the linked list: and a node of 00, when the node exists, the node is taken as the node corresponding to the period to which the first unit time belongs.
In an optional embodiment, when it is determined according to the first timestamp that the first unit time is not the first unit time in the period to which the first unit time belongs, and based on the first timestamp, the node corresponding to the period is not found in the linked list, the method further includes:
When the node does not exist, a storage address corresponding to the electric parameter at a preset storage position is obtained; judging the period of the first unit time corresponding to the first time stamp based on the first time stamp; determining a second timestamp of the first piece of data in the period; adding a node in the linked list, and configuring a preset number of status bits in the node; storing the second time stamp and the storage address in the node, modifying the initial state information of the state bit corresponding to the first time stamp into preset state information, taking the second time stamp as the initial time stamp of the node, and taking the storage address as the head address of the node.
Illustratively, in the present embodiment, the unit time is one minute and the period is one day. As in 2022/12/13, a power outage event occurs, with the power outage time ranging from zero in the morning to eight am. When a power is received at eight am, one piece of power data is updated, and the first timestamp corresponding to the piece of power data is 2022/12/13/8:01, because the piece of power data is not the power data acquired in the first unit time of the day, after the piece of power data is acquired, and the electric parameters in the piece of power data are stored in a preset storage position, the node corresponding to the day needs to be searched from the linked list. The power failure may be due to the fact that no power data is obtained in the first unit time of the day, and thus no node corresponding to the day exists in the linked list.
Therefore, when the first unit time is determined not to be the first unit time in the period to which the first unit time belongs according to the first timestamp, and the node corresponding to the period is not found from the linked list based on the first timestamp, the storage address corresponding to the electric parameter in the electric energy data at the preset storage position is acquired first. Next, the period to which the unit time corresponding to the first time stamp belongs, that is, 2022/12/13 is determined according to the first time stamp 2022/12/13/8:01 of the piece of electric energy data. And determining that the second timestamp of the first piece of data in the period is 2022/12/13/0 according to the judged period: 00. finally, a new node is added to the linked list, 1440 status bits are configured in the node, and a second timestamp 2022/12/13/0 is obtained: the storage address of the electrical parameter corresponding to 00 and the first timestamp in the preset storage position is stored in the newly added node, and meanwhile, the initial state information 0 on the state bit corresponding to the first timestamp 2022/12/13/8:01 is modified into preset state information 1. And second timestamp 2022/12/13/0:00 is used as an initial time stamp of the newly added node, and a storage address corresponding to the electric parameter is used as a head address of the newly added node.
In an alternative embodiment, after receiving the data search instruction, determining the existence state of the electrical parameter based on the data search instruction further includes:
S21: and reading the data searching instruction, and extracting the target time stamp from the data searching instruction.
Specifically, the target timestamp refers to a timestamp corresponding to the power data to be searched.
S22: and searching out the target node corresponding to the target period from the linked list based on the target timestamp.
Specifically, the target period is a storage period to which the target unit time corresponding to the target timestamp belongs.
Illustratively, if the target time stamp is 2022/12/15/17:32, the period of the unit time corresponding to the target time stamp, that is 2022/12/15, is determined based on the target time stamp. The second timestamp 2022/12/15/0:00 of the first piece of data in the period is determined, the second timestamp is taken as an index, the node with the initial timestamp 2022/12/15/0:00 is searched from the pre-constructed linked list, and when the node is searched, the node is determined to be a target node.
S23: an initial timestamp of the target node is obtained.
S24: the offset of the target unit time in the period is determined based on the target time stamp, the initial time stamp, and the duration of the target unit time.
For example, the target time stamp is 2022/12/15/17:32, the initial time stamp of the target node is 2022/12/15/0:00, the number of minutes between the two time stamps can be determined to be 1052 based on the target time stamp and the initial time stamp, and the duration of the target unit time is 1 minute, which is equivalent to the target unit time corresponding to the target time stamp being the 1052 nd unit time in the affiliated period, namely, the offset is 1052.
S25: the state information on the state bit corresponding to the target timestamp is determined starting with the first state bit in the target node and using the offset as the movement distance.
Illustratively, 1440 status bits are included in the target node, starting with (including) the first status bit, moving 1052 status bits, determining the 1052 th status bit as the status bit corresponding to the target timestamp 2022/12/15/17:32, and determining the status information on the status bit as the target status information.
S26: and comparing the state information with preset state information, and determining the existence state of the electric parameter corresponding to the target timestamp based on the comparison result.
Specifically, the preset state information is state information on a corresponding state bit when the electric parameter exists.
For example, in the present embodiment, the state information is 0 or 1,0 indicates that the electrical parameter is not present, and 1 indicates that the electrical parameter is present, and thus the preset state information is 1. Comparing the target state information with preset state information, when the target state information is 1, indicating that the electric parameter corresponding to the target time stamp exists, and when the target state information is not 1, indicating that the electric parameter corresponding to the target time stamp does not exist, and no query operation is needed.
In an alternative embodiment, when the electrical parameter exists, acquiring the electrical parameter corresponding to the target timestamp, and further including:
s31: and acquiring state information on all the state bits before the state bit corresponding to the target timestamp.
For example, still in the above embodiment, the state bit corresponding to the target timestamp is the 1052 th state bit, and when the electrical parameter corresponding to the target timestamp exists, the state information on each state bit before the 1052 nd state bit is acquired.
S32: and counting the number of the state bits, of which the state information on all the state bits is preset state information, and determining the number as the effective data quantity.
Illustratively, the number of state bits whose state information matches the preset state information on the previous 1051 state bits is counted, and the number of counted ends is the number of valid data existing in the present period, that is, the valid data amount, before the target state bit.
S33: and calculating a target storage address corresponding to the target electric energy data based on the head address and the effective data quantity.
Specifically, the target storage address=the head address+the effective data amount.
Illustratively, since the 1000 valid data amounts are counted before the 1052 nd state bit and the 1052 nd state bit is also valid, in this cycle, there are 1001 valid data pieces in total, which corresponds to 1001 electrical parameters stored in a preset storage location. Assuming that the storage address corresponding to the first electrical parameter is 0001, the storage address corresponding to the 1001 st electrical parameter is 0001+1000=1001, and 1001 is the target storage address.
S34: and acquiring an electric parameter corresponding to the target timestamp from a preset storage position based on the target storage address.
Specifically, after the target storage address is determined, the electric parameter corresponding to the target timestamp can be obtained from the preset storage position according to the target storage address.
In an alternative embodiment, when the electric energy meter time is changed from the first time to the second time, the method further comprises:
Searching a first node from the linked list based on the first moment, and searching a second node from the linked list based on the second moment; screening out the state bits corresponding to each unit time between the first time and the second time from all the state bits contained in the first node and the second node; and modifying the state information on all the screened state bits into initial state information.
Illustratively, when the first time is less than the second time, assuming the first time is 2022/12/15/2:00 and the second time is 2022/12/15/2:10, the updating of all data before the first time has been completed before the first time is changed to the second time, and the subsequent data updating is started from the second time after the first time is changed to the second time, then a "neutral period" without data updating is formed between the first time and the second time. Therefore, the state information on the state bit corresponding to each unit time contained in the "neutral period" can be directly modified to the initial state information. The initial state information is "0", that is, the state information corresponding to the 10 state bits is 0, which indicates that no electric energy data is obtained in 10 unit time corresponding to the 10 state bits respectively.
Illustratively, when the first time is greater than the second time, the first time is 2022/12/15/2:10, and the second time is 2022/12/15/2:00, and the data has completed updating at the first time, i.e., the status bits have been updated to the status bits corresponding to 2:10, before the first time is changed to the second time. After changing the first time to the second time, the subsequent data update starts from 2:00, which is equivalent to the data on the status bits between 2:00-2:10 needing to be updated again. Therefore, the state information on the state bits between 2:00-2:10 needs to be cleared, i.e. all state information is modified to be the initial state information 0, before the time change is made.
