Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.

Referring to fig. 2, in a first embodiment of the method for recording electric quantity of an electric energy meter according to the present invention, the method for recording electric quantity of an electric energy meter includes:

step S100, judging whether to record the electric information according to the current time;

at present, the use of an electric energy meter is distributed in an electric power system, and the electric energy meter can be directly connected to a circuit to measure household electricity consumption information under the conditions of low voltage and low current in a household environment; under the condition of high voltage or large current, the electric energy meter cannot be directly connected to a circuit and needs to be matched with a voltage transformer and a current transformer for use. In either case, since the amount of electricity used varies with time, it is necessary to record the electricity information measured by the electric energy meter after the electricity information is measured. Generally, the electric energy meter comprises a microprocessor, a measuring module, a memory and other components; the microprocessor is used for generating an electricity utilization information recording instruction according to time and rules preset by a user so as to control the electric energy meter to record the electricity utilization information, and the recording mode can be table recording or can be recording through a histogram or a curve graph; the measuring module is used for measuring the electricity consumption of the load electrically connected with the electric energy meter according to the electricity consumption information instruction, and the memory is used for recording the electricity consumption information measured and obtained by the measuring module.

In some embodiments, the recording of the load curve by the electric energy meter itself is a commonly used recording manner of the electric energy meter, a Memory is required to implement the function of recording the load curve by the electric energy meter, the method of recording the load curve generally includes recording a recording time and an electric quantity, recording a piece of recording information at intervals, contents of each piece of recording information include a current time and a total value of the current electric quantity, and sequentially storing each piece of recording information in the Memory, where the Memory may be an EEPROM (Electrically Erasable Programmable Read-Only Memory), a FLASH Memory, and the like, where the EEPROM Memory records a small amount of data, and the FLASH Memory has a large recording amount but is expensive, so that the above-mentioned manner generally occupies too much Memory space for the recording of the electric information, and has a high recording cost. In this embodiment, the recording of the electricity consumption information is regular, and the current time needs to be judged before the electricity consumption information is recorded, and whether the electricity consumption information is recorded or not is judged according to the current time, so that the recording condition of the electricity consumption information meets the knowledge requirement of the user on the electricity consumption information, and confusion is avoided. The recording of the electricity utilization information can be periodic, and the recording interval period can be 1, 5, 10, 15, 30 and 60 minutes; the recording of the electricity utilization information can be not periodic, but accords with a preset recording rule, and a user can adjust the electricity utilization information randomly according to the requirement of the user.

Step S200, if the electricity information is recorded, judging whether the electricity information recorded at this time accords with a first preset rule;

in this embodiment, whether or not to record the electrical information is determined. If the electric information needing to be recorded at the current time is obtained through judgment, whether the current recording meets a first preset rule or not is continuously judged; if the current time is judged to be unnecessary to record the electric information, no operation is required to be executed. The first preset rule is a rule preset by a person skilled in the art according to requirements and used for distinguishing the recording modes of the electricity consumption information. The first preset rule may be that the total power consumption is higher than a certain preset value, that the power consumption increase in a period of time is higher than a certain preset value, or that the current time is within a certain special period of time.

And step S300, if the record does not accord with a first preset rule, calculating the power consumption increment of the load within a first time length and recording the power consumption increment.

In this embodiment, if the record conforms to a first preset rule, the current accumulated total amount of power consumption of the load connected with the electric energy meter is obtained, and the current accumulated total amount of power consumption is recorded. The first preset rule is used for distinguishing the mode of recording the electricity utilization information. In some embodiments, if the record conforms to a first preset rule, the accumulated total power consumption amount of the load connected to the electric energy meter is recorded, that is, the display numerical value of the electric energy meter is read, and if the record does not conform to the first preset rule, the power consumption increment of the load connected to the electric energy meter in a first time period is recorded, that is, the difference between the display numerical value of the current electric energy meter and the display numerical value of the electric energy meter before the first time period is calculated, and the difference is used as the power consumption increment value in the first time period and is recorded. The first time duration is adjusted by a person skilled in the art according to a preset rule, and may be 1, 5, 10, 15, 30, 60 minutes or any other time duration. The recording may be performed by recording the electricity information in the memory in the clear text, or by encrypting the electricity information, storing the encrypted electricity information in the memory, and decrypting and reading the electricity information when the user needs to read and apply the electricity information.

In the scheme, the storage comprises a first storage unit and a second storage unit, the first storage unit is used for receiving and storing the electricity consumption increment information, and the second storage unit is used for receiving and storing the electricity consumption total amount information.

By recording the electricity information in the form of distinguishing the recording mode of the electricity information by the first preset rule, the recording of the electricity information can be flexibly adjusted when different customer requirements are met, the requirements of multiple customers can be met, meanwhile, the space of a memory can be saved in the recording process, and the safety of the electricity information can be protected by encrypting the electricity information.

In one embodiment, the step of determining whether to record the electrical information according to the current time includes:

calculating a time length difference value between a time node of the current time and a time node of the power-on time of the electric energy meter;

and determining whether to record the electric information according to a judgment result of judging whether the time length difference is integral multiple of the first time length.

In this embodiment, the memory includes an electric energy meter clock and a first determining unit, the electric energy meter clock may be a soft clock or a hard clock, and the electric energy meter clock is used to record a time node of current time and a time node of power-on time of the electric energy meter. And the first judging unit judges whether to record the electricity information according to the time length difference between the time node of the current time and the time node of the electricity time of the electric energy meter. After the electric energy meter is powered on and the first time length is set by a user, the electric energy meter needs to obtain a time length difference value between a current time point and a power-on time point of the electric energy meter in real time and convert the time length difference value into a time length unit unified with the first time length. And then judging whether the time length difference is integral multiple of the first time length. And if the time length difference is not the integral multiple of the first time length, the electricity utilization information at the current time is not recorded. For example, the power-on time point is an eighth integer of any day, the current time point is a fifteenth integer of ten points of the day, if the first time length is 15 minutes, the time length difference between the current time point and the power-on time point of the electric energy meter is 135 minutes, and is exactly an integral multiple of the first time length, the power utilization information at the current time is recorded. By comparing the time length difference with the first time length, the electricity information can be recorded uniformly according to the time interval set by the user, so that the user can obtain the complete and continuous electricity utilization condition.

In one embodiment, whether the current record is the first record of the current day is judged;

and if the current record is the first record of the current day, judging whether the current record meets a first preset rule according to the first record of the current day.

In this embodiment, the first preset rule is that the current record is the first record of the current day, and therefore, it is determined whether the current record meets the first preset rule, that is, whether the current record is the first record of the current day is determined. Namely: if the current record is the first record of the current day, acquiring the current accumulated total amount of power consumption of a load connected with the electric energy meter, and recording the current accumulated total amount of power consumption; and if the record is not the first record of the day, calculating the electricity consumption increment of the load in the first time length and recording the electricity consumption increment. That is, only when recording for the first time every day, the current accumulated total power consumption of the load connected with the electric energy meter is recorded, and the power consumption increment is recorded when recording for other times. The recording mode can also completely and clearly acquire the use condition of the electric energy meter.

In some embodiments, when the accumulated total amount of power consumption is recorded, each piece of recorded information at least includes recording time (5 bytes), forward active power (4 bytes), reverse active power (4 bytes), forward reactive power (4 bytes) and reverse reactive power (4 bytes), and each piece of record occupies 21 bytes of storage space in the memory; when the power consumption increment is recorded, the recording time is not recorded, and the forward active power quantity (4 bytes), the reverse active power quantity (4 bytes), the forward reactive power quantity (4 bytes) and the reverse reactive power quantity (4 bytes) are replaced by the corresponding forward active power quantity increment (2 bytes), reverse active power quantity increment (2 bytes), forward reactive power quantity increment (2 bytes) and reverse reactive power quantity increment (2 bytes); at this time, each piece of record information occupies a storage space of 8 bytes in the memory. In this way, the recorded electricity accumulated total amount is replaced by the recorded electricity increment, and 13 bytes of storage space can be saved for each piece of electricity information. Therefore, by applying the recording mode, the clear and complete recording of the power utilization information is ensured, the storage space of the memories can be greatly saved, the number of the recorded information which can be stored in each memory is greatly increased, and the recording cost is greatly saved.

In an embodiment, the step of determining whether the current record is the current record includes:

and if the record is the first record after the electric energy meter is electrified, resetting the numerical value of the day counter and the numerical value of the interval counter to zero, and judging that the record is the first record on the day.

In this embodiment, the memory further includes a second judging unit, and after the first judging unit judges the electricity information for recording, the second judging unit is configured to judge whether to record the total electricity consumption amount or the electricity consumption increment according to whether the current recording is the first recording of the current day. The second judging unit comprises a first judging subunit and a second judging subunit. The first judging subunit is used for judging whether the record is the first record of the electric energy meter after being electrified; the second judging subunit is configured to judge whether the current record is a first record of the day other than the first record of the electric energy meter after being powered on. It should be noted that the judgment of the electric energy meter on the day is not based on the time of the natural day or any longitude and latitude, but the power-on time of the electric energy meter is used as the judgment basis, that is, the first 24 hours after the electric energy meter is powered on is counted as the first day, the second day is counted from the 25 th hour to the 48 th hour, and so on. And a day counter and an interval counter are arranged on the electric energy meter, and the operation of the day counter and the interval counter is controlled by the electric energy meter. Based on this, in the scheme, the first recording in the same day is divided into two situations, the first situation is that the current recording is the first recording after the electric energy meter is powered on, and the second situation is that the time length difference between the current recording and the first recording of the electric energy meter is an integral multiple of 24 hours. The scheme separately judges the two conditions; firstly, judging whether the record is the first record after the electric energy meter is powered on, if the record is the first record after the electric energy meter is powered on, judging that the record is the first record in the day, recording the current accumulated total amount of the electricity consumption of a load connected with the electric energy meter, and zeroing the numerical values of a day counter and an interval counter. And if the record is judged not to be the first record after the electric energy meter is electrified, continuously judging whether the time length difference between the record and the first record of the electric energy meter is integral multiple of 24 hours. Zeroing the values of the day counter and the interval counter means starting a completely new recording of the electric energy meter. In general, the interval counter and the day counter before the electric energy meter is powered on can automatically return to zero, and the interference of previous records on the current record is reduced.

In an embodiment, after the step of determining whether the current record is the first record after the power-on of the electric energy meter, the method further includes:

if the record is not the first record after the electric energy meter is electrified, adding one to the numerical value of the interval counter, and judging whether the numerical value on the interval counter is greater than a first numerical value or not;

if the numerical value is larger than the first numerical value, the numerical value of the interval counter is reset to zero, the numerical value of the day counter is increased by one, and the current record is judged to be the first record of the day;

and if the numerical value is less than or equal to the first numerical value, judging that the record is not the first record of the day.

In this embodiment, if the record is not the first record after the power on of the electric energy meter, it is continuously determined whether the record is the first record on the day other than the first day. After the record is known not to be the first record after the electric energy meter is powered on, the interval counter is adjusted before each record, namely the numerical value of the interval counter is increased by one, and the increase of the interval counter by one means that the electric energy meter performs one record, and after the increase of the numerical value by one, whether the record is the first record of the day other than the first day is judged according to the numerical value on the interval counter. Wherein, the first value is a value preset by a person skilled in the art according to a specific requirement. In one embodiment, the first time period is 15 minutes and the first value is 96. Therefore, the scheme in this embodiment is: and if the record is not the first record after the electric energy meter is electrified, adding one to the interval counter, judging whether the numerical value of the interval counter is greater than 96, if so, returning the numerical value of the interval counter to zero, adding one to the numerical value of the day counter, and considering the record as the first record on the day. Because the first recording interval is 24 hours every two days, namely 96 times of 15 minutes, the electric energy meter records the electricity utilization information every 15 minutes, the interval counter is increased by one before each recording, and if the initial value of the interval counter is 0, the 97 th recording is just 24 hours away from the 1 st recording.

According to the method, the electricity utilization information of the electric energy meter is recorded, and the first recording time of each day can be accurately calculated, so that the recording process of the electricity utilization information is accurate and complete.

Referring to fig. 3, in an embodiment, the step of recording the current accumulated total amount of power consumption includes:

and sequentially recording the current time, the positive active electric quantity accumulated total value, the negative active electric quantity accumulated total value, the positive reactive electric quantity accumulated total value and the negative reactive electric quantity accumulated total value.

Referring to fig. 4, in an embodiment, the step of recording the power consumption increment includes:

and sequentially recording a forward active electric quantity increment value, a reverse active electric quantity increment value, a forward reactive electric quantity increment value and a reverse reactive electric quantity increment value.

In this embodiment, no matter whether the value is an accumulated total value or an incremental value, the values of the forward active electric quantity and the reverse active electric quantity are positive values, and only if the current directions are opposite, the forward active electric quantity and the reverse active electric quantity both work on a load connected to the electric energy meter; the forward reactive electric quantity and the reverse reactive electric quantity are both positive values and opposite in current direction, and the forward reactive electric quantity and the reverse reactive electric quantity consume electric energy even though the forward reactive electric quantity and the reverse reactive electric quantity do not apply work to a load connected with the electric energy meter, so that the electric energy meter can record the electric energy quantity. After the data is recorded in the memory, the data can be exported in a form convenient for the user to refer to. The derivation mode can be that the derivation is carried out through a preset data record table, the electricity utilization information is automatically generated in the preset data record table according to a pre-written program, the derivation can also be carried out in a text mode, and the derivation can also be carried out in a curve coordinate graph, wherein in the curve coordinate graph, the horizontal axis can be time, and the vertical axis can be electricity consumption.

Because the value of the electricity consumption increment is not too large, only two bytes of storage space are reserved for each recording, and the current time is not required to be recorded because the recording interval time of each recording is equal, so that the electricity consumption increment is much smaller than the storage space required for recording the accumulated total amount of the electricity consumption.

In an embodiment, after the step of determining whether the current record meets the first preset rule, the method further includes:

and if the record conforms to a first preset rule, acquiring the current power consumption accumulated total amount of a load connected with the electric energy meter, and recording the current power consumption accumulated total amount.

In this embodiment, before each recording, it is necessary to determine whether the recording of the power consumption information can be supported for one time according to the remaining storage space; and if the residual storage space can support the recording of the primary power utilization information, recording the power utilization information, and if the residual storage space cannot support the recording of the primary power utilization information, stopping the subsequent recording step and prompting the user to replace the memory. Therefore, the situations of data confusion, data loss and the like caused by insufficient memory space can be avoided.

In addition, the electric energy meter also comprises a display module which can be a display screen. The display screen can be used for showing current time at least to and this electric energy meter power on, electric quantity such as current forward active electric quantity, reverse active electric quantity, forward reactive electric quantity and reverse reactive electric quantity, the display screen can also show the user-defined power consumption increment of duration. Through the electric energy meter display module, a user can know the power utilization condition of the current electric energy meter connected with the load at any time and the power utilization condition of the load within a certain time.

The invention also proposes an electric energy meter comprising a memory, a processor, and a computer program stored on said memory and executable on said processor for performing the method according to the various embodiments of the invention.

The invention also proposes a readable storage medium on which the computer program is stored.
