Description
Technical Field
The invention relates to the field of electric energy meters, in particular to an electric energy meter data complementary copying method based on a mirror image method.
Background
In the field of electric power, a terminal and a certain number of electric energy meters form a data acquisition network. In the data acquisition network, the terminal is responsible for acquiring the data of the electric energy meter in the transformer area, for example, the terminal generally acquires the data of the electric energy meter managed in the district through a 485 communication mode, and then stores the response data information of the electric energy meter in the terminal.
According to the technical condition requirements in the electric power field, the terminal needs to have the function of collecting the load curve of the electric energy meter, namely, the terminal can read the data of the electric energy meter at a fixed time so as to form a curve by using the read data of the electric energy meter. For example, the curve formed after the terminal is processed may be a 15-minute curve, that is, the terminal collects data of the electric energy meter at 0 point, 0 minute time, 0 point, 15 minute time, 0 point, 30 minute time, … time, 23 point, and 45 minute time, and then stores the electric energy meter data collected at these times in the terminal.
In the actual reading process, due to the influence of factors such as power failure of the terminal, meter reading line faults or electric energy meter faults, the situation that the terminal cannot acquire electric energy meter data at a certain moment may occur, so that the electric energy meter data in the terminal is incomplete or lacks of the electric energy meter data at certain moments. In addition, according to the technical conditions of the power field, if the terminal does not read the data of the electric energy meter within the specified time, the terminal is provided with an automatic supplementary reading function. That is to say, at this time, it is necessary that the terminal can perform self-check on the electric energy meter data stored in the terminal itself, and perform supplementary reading operation on the electric energy meter data that is self-checked out and is lacking, so that the integrity of the read electric energy meter data and the success rate of reading are improved.
Of course, there are various methods for reading the load curve of the electric meter by the terminal, and the load data of the electric meter at a single point can be read at a fixed time point, or the load data at a plurality of time points can be read at intervals according to the fixed load curve within a fixed time period. For example, the terminal may read load data of the electric energy meter at the time point of 8:00, or may read load data of 4 time points within a fixed time period of 8:00 to 9:00 and with a fixed load curve interval of 15 minutes.
As described above, the curve meter reading process of the terminal mainly includes the normal curve meter reading process and the curve complementary reading process. Specifically, the method comprises the following steps:
the normal curve meter reading process is that the terminal reads the data of the electric energy meter according to the meter reading interval, and the meter reading interval parameter on the terminal is a settable parameter;
the curve complementary reading process is that the terminal adopts the data of the electric energy meter which is subjected to complementary reading in fixed time, namely after the data of the electric energy meter is read once, the terminal tries to read the data (also called as leakage point data) of the electric energy meter which is not read in the previous time again in fixed time point. For example, the terminal traverses at 0 point and 0 point whether the previous day has the missing point data, and if the missing point data needs to be subjected to complementary copying, the terminal once again performs complementary copying on all the data in the previous day and then stores the data. However, the existing electric meter data copying scheme also has the following defects:
firstly, the terminal is set to make up reading the electric meter data at a fixed time point, and the electric meter data needing to be read is usually more, so that the normal reading process of the terminal is easily influenced by executing the making up reading process;
secondly, the supplementary reading process executed by the terminal is not instant, and the supplementary reading is started the next day after the terminal finds that the missing point data exists, so that the electric meter data obtained by the supplementary reading is not timely.

And 4, the terminal determines a new additional reading time point again according to the obtained mirror image time point and the load data condition of the historical storage electric meter:
when the obtained mirror image time point has no ammeter load data, taking the mirror image time point as a new complementary reading time point, and additionally reading ammeter load data corresponding to the new complementary reading time point;
when the obtained mirror image time point has the ammeter load data, the terminal uses the mirror image time point as a starting time and uses the load curve interval as a search interval, and ergodic search is carried out on the ammeter load data corresponding to a time before the starting time, and the step 5 is carried out; the terminal sets the maximum search times according to the times of traversing and searching forwards from the time;

Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the present embodiment provides a method for copying data of an electric energy meter based on a mirror image method, including the following steps:
step 1, a terminal detects and judges whether a previous round of additional reading time point in an additional reading flow is stored in the terminal:
when the terminal determines that the time point of the previous round of additional reading is stored, the step 2 is carried out;
when the terminal determines that the time point of the previous round of additional reading is not stored, the step 3 is carried out; the terminal referred to in this embodiment is a concentrator;
step 2, obtaining a load curve interval of the terminal, processing the load curve interval to obtain a mirror image time point when the terminal executes the reading operation by combining the stored time point of the previous round of additional reading, and turning to step 4, wherein the load curve interval of the terminal is marked as △ t, the load curve interval △ t is set to be 15min in the embodiment, and the load curve interval of the previous round of additional reading is set to be 15minThe interval point is marked as tSupplement copy machineAnd the mirror image time point when the terminal executes the reading operation is marked as tMirror image，tMirror image＝tSupplement copy machine-△t；
For example, if the power-on time of the terminal is 8:00, the interval of the load curves is 15 minutes, and the complementary reading point of the previous round of the complementary reading process is 6:00, the mirror image time point when the terminal executes the reading operation under the condition is determined to be 5: 45;
step 3, acquiring the power-on time of the terminal and the current time of the terminal, processing to obtain a mirror image time point of the terminal for executing the reading operation, and turning to step 4; wherein, the power-on time of the terminal is marked as tPowering upThe current time mark of the terminal is tAt presentAnd the mirror image time point when the terminal executes the reading operation is marked as tMirror image，tMirror image＝tPowering up-(tAt present-tPowering up)；
For example, the terminal is powered on at time tPowering upI.e. mirror start time t0Is t0＝tPowering upThe current time of terminal operation is tAt presentAnd then the mirror image time point t when the terminal executes the reading operationMirror imageComprises the following steps:
tmirror image＝tPowering up-(tAt present-t0)
＝tPowering up-(tAt present-tPowering up)；
E.g. terminal power-on time tPowering up8:00, and a load curve interval △ t of 15 minutes, the start time t of the mirror image0Is 8: 00; when the terminal runs to 8 points and 15 points, the complementary copying process is started, and the calculated mirror image time point t is obtainedMirror imageIs 7: 45;
and 4, the terminal determines a new additional reading time point again according to the obtained mirror image time point and the condition of the historical stored electric meter load data (also called electric meter load curve data):
when the obtained mirror image time point has no ammeter load data, the additional reading point is the mirror image time point, the mirror image time point is taken as a new additional reading time point, and ammeter load data corresponding to the new additional reading time point is additionally read;
when the obtained mirror image time point has the ammeter load data, the terminal does not need to copy the ammeter load data of the mirror image time point, the terminal takes the mirror image time point as a starting time and takes the load curve interval △ t as a search interval, and conducts traversal search on the ammeter load data corresponding to the time before the starting time, and then the step 5 is carried out, wherein the number of times of traversal search forward from the starting time of the terminal is set as the maximum search number to avoid that the traversal search process of the terminal is trapped in a dead cycle and takes too long time;
step 5, when the terminal judges that the electric meter load data of the moment corresponding to the current search is not stored, the terminal copies the electric meter load data of the moment corresponding to the current search; otherwise, the terminal records the time point corresponding to the searched latest ammeter load data, and the time point is used as the additional reading time point when the terminal executes the next round of additional reading process.
Specifically, for example, when the terminal runs to 8 points and 15 points, the complementary copying process for the load data of the electric meter is entered, and the calculated mirror image time point t is obtainedMirror imageIs 7: 45; the terminal checks and judges whether the terminal stores data of the electric energy meter at 7 points and 45 points:
if the terminal does not store the data of the electric energy meter at 7 points and 45 points, namely the mirror time point tMirror imageNo electric meter load data exists, so the terminal performs the additional reading process to read the 7-point 45-point electric energy meterLoading curve data, storing the copied and read data to a corresponding position of the terminal, recording and storing the complementary copying point of the time, and ending the complementary copying process;
if the terminal stores the data of the electric energy meter at 7 points and 45 points, namely the mirror image time point tMirror image(7 point 45 points) when the electric meter load data exists, the terminal checks and judges whether the electric meter load data of 7 points 30 points of the electric energy meter is stored: if the electric meter load data at 7 points and 30 minutes does not exist, the terminal copies the electric meter load curve data at 7 points and 30 minutes additionally, stores the read data to the corresponding position of the terminal, then records and stores the copied points additionally, and the complementary copying process is ended;
of course, if the terminal detects that the terminal stores the electric meter load data of the electric meter at 7 o 'clock and 30 o' clock, the terminal continues to look ahead, and so on.
In the process of continuing to find forward by analogy, if the corresponding time points for 10 times continuously have the condition of the electric meter load data, the current round of additional reading operation is not executed under the condition, and then the terminal stores the corresponding additional reading point record for the tenth time, so that the next round of additional reading operation is entered, and the operation is repeatedly executed according to the previous round of additional reading operation.
Of course, in the present embodiment, the mirroring time point of the concentrator as the terminal is set to be configurable; for example, re-mirroring is performed at 0 o 'clock each day, or 3 times per day at 0 o' clock, 8 o 'clock, or 16 o' clock each day.
In addition, after the zero point of each day is passed by the terminal, the terminal takes the zero point moment as the power-on time of the terminal in the step 3, namely, let tPowering up＝0:00。
