With the wide application of power terminals, people have higher and higher environmental requirements on the application of power terminals, and people hope that the power terminals can meet the requirements of office selective examination, namely data reading of 1 meter station area, and can also meet the requirements of data reading of common small station areas, common middle station areas and common large station areas.
Although the conventional power terminal can distinguish the sizes of the transformer areas and complete the reading of data of different transformer areas, the same data acquisition mode is adopted for all the transformer areas, and the corresponding data acquisition modes cannot be selected according to the characteristics of different transformer areas, so that a great deal of resource waste is caused.
For example, the small transformer area requires a large number of reading data items and a large number of point reading data items because of the small number of meters, and when the power terminal adopting the acquisition mode is used in a large transformer area, the large transformer area easily cannot completely read the data items because of the large number of meters in the large transformer area, and the success rate of reading the data items is low. And if the power terminal adopting the data acquisition mode is used in a common cell area, the data reading is incomplete due to too few reading data items, and the data reporting integrity rate is influenced.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The method for selecting a data acquisition mode according to a station area environment according to the application shown in fig. 1 comprises the following steps,
s1, acquiring the meter quantity L contained in the current station area;
s2, judging the current distribution room mode according to the meter quantity L, and selecting a first data acquisition mode to acquire data when the current distribution room mode is judged to be the distribution room mode; when the current station area mode is judged to be the cell area mode, selecting a second data acquisition mode to acquire data; when the current distribution room mode is judged to be the middle distribution room mode, selecting a data acquisition mode III to acquire data; and when the current distribution area mode is judged to be the large distribution area mode, selecting a data acquisition mode IV for data acquisition.
Specifically, the method S2 specifically includes determining that the current station area mode specifically includes according to the table count L,
judging the size relationship between L and the numbers m, n, p and q, if L is less than m, indicating that the current station area is in a station body mode; if m is less than or equal to L and less than n, the current cell is in a cell mode; if n is more than or equal to L and less than p, the current station area is in a middle station area mode; if p is less than or equal to L and less than or equal to q, the current cell is in a large cell mode.
In this embodiment, the value of m is 2, the value of n is 5, the value of p is 401, and the value of q is 1000, and of course, the specific table area modes including how many tables belong to can be divided according to actual needs and experience, which is the division according to the national network requirements.
Meanwhile, a first data acquisition mode specifically comprises the steps of reading the data once every t minutes, reading common data items, judging a platform alarm and reading all day frozen data each time; the second data acquisition mode specifically comprises the steps of reading the data once every T minutes, and uniformly reading the data with the first priority in the event and the daily freezing data every time; the third data acquisition mode specifically comprises reading data with a second priority in the day freezing data; the data acquisition mode four specifically comprises reading data with a third priority in the day freezing data. In this embodiment, T takes a value of 5, and T takes a value of 15.
Because the daily freezing data comprises a priority data item, an important data item, a common data item and an unimportant data item, the sizes of the transformer areas are different, and the requirements on the types of data copying and reading are also different.
In the application, the priority data item, the important data item and the common data item are classified into data of a first priority, the priority data item and the important data item are classified into data of a second priority, and the data of a third priority comprises the priority data item, so that a data acquisition mode matched with the priority data item can be selected according to a transformer area mode, data acquisition requirements under different environments are met, data acquisition efficiency and integrity are ensured, and the applicability of the power terminal is greatly improved.
Specifically, if L is equal to 1 (stage test, 1 table zone), the meter reading is performed according to the default 5 minutes, the common data items are copied, the stage alarm is judged, and all common daily freezing data including priority data, important data, common data and unimportant data are copied and read.
If L is equal to L1 (the value range is 2-4), no matter how many meter reading intervals are, the automatic adjustment is 15 minutes, because if the meter reading intervals are too few, the event data cannot be read in a point-to-point manner, because the event data can be read in one point-to-point manner within 2 minutes, and then priority data, important data and common data in the frozen data are read in a reading day.
If L is equal to L2 (the value range is 5-400), no matter how many meter reading intervals, the parameter cannot be used, because the event data is executed only after the daily freezing reading is finished, and only the priority data and the important data in the daily freezing data are read, because if too many data are read, the electric power terminal cannot finish reading, only data loss is caused, and the integrity of data reporting is influenced.
If L is equal to L3 (the value range is 401-1000), no matter how many meter reading intervals, the interval period is not used, because the event data is not read, but only the priority data in the daily frozen data is read, so that the integrity of data reporting is affected because too many data are read, the power terminal cannot finish the reading in one day, and therefore the priority data only concerned by the user is preferentially collected.
In order to better improve the applicability of the power terminal, the method may further include the step S1 of obtaining the number L of meters included in the current station area, which includes obtaining the number L of meters of the carrier measurement point after the power terminal is powered on and normally operates, and may also be obtained by manually counting the number L of meters in the current station area.
As shown in fig. 1, when the meter count L is obtained by obtaining the carrier measurement point, the data collection manner in step S2 is selected by the automatic analysis and judgment of the power terminal; when the meter quantity L is obtained by manual counting, the data collection mode in step S2 is selected by manually operating a mode switch on the liquid crystal of the power terminal.
That is, the liquid crystal of the power terminal is provided with a selection switch corresponding to the distribution room mode, the selection switch is twisted to the corresponding distribution room mode gear after the current distribution room mode is artificially judged according to the number of the current distribution rooms, and the MCU in the power terminal selects the corresponding data acquisition mode to acquire data after receiving the signal, so that the problems of inaccurate selection of the data acquisition mode, incomplete data acquisition and low data acquisition efficiency caused by the automatic analysis and judgment error of the power terminal are reduced, and the manual calibration is convenient to perform according to actual needs.
While embodiments of the invention have been shown and described, it will be understood by those skilled in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
