Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a method for determining a target platform area to which an electric meter belongs according to an embodiment of the present invention, where the embodiment is applicable to a case of determining the platform area to which the electric meter belongs, and the method may be executed by a device for determining the target platform area to which the electric meter belongs in the embodiment of the present invention, and the device may be implemented in a software and/or hardware manner, and optionally, may be implemented by an electronic device, and the electronic device may be a mobile terminal, a PC terminal, a server terminal, or the like. The apparatus may be configured in a computing device, and the method for determining a target distribution area to which an electricity meter belongs specifically includes the following steps:
and S110, acquiring a to-be-processed data set of a plurality of to-be-processed electric meters within a preset time length.
The electric meter to be processed can be understood as the electric meter of the region to which the electric meter needs to be determined. The data group to be processed refers to data for determining a region to which the electric meter belongs, and may be electric characteristic parameter data of the electric meter, such as voltage, current, power frequency, and the like, or fluctuation data of the voltage or the current. The to-be-processed data set includes voltage data at a plurality of discrete moments, for example, a large number of discrete acquisition moments may be preset, and data acquired at each discrete acquisition moment may be used as the to-be-processed data set. The preset time duration refers to the preset time used for calling the electric meter data, and optionally, the preset time duration may be 30 hours or 100 hours. For example, in practical application, the electrical characteristic parameters corresponding to each electric meter may be prestored in the database, when the area to which the electric meter a, the electric meter B, and the electric meter C belong needs to be determined, the interface may be used to respectively call the electrical characteristic parameters of the electric meter A, B, C, such as voltage, current, power frequency, and the like, in a preset time period from the database, each electric meter and the corresponding electrical characteristic parameters may be used as a set of data to be processed, correspondingly, three sets of data to be processed corresponding to the electric meter a, the electric meter B, and the electric meter C may be obtained, and the three sets of data to be processed may be used as a set of data to be processed. At this time, it can be considered that three to-be-processed data sets are acquired. Correspondingly, the data group to be processed corresponding to the multiple electric meters to be processed within the preset time length can be obtained.
S120, for each data group to be processed, determining voltage jump data of two adjacent moments in the current data group to be processed, and recording jump moments when the voltage jump data are larger than a preset jump data threshold value to obtain a data jump set corresponding to the current data group to be processed.
When the voltage jump data in each to-be-processed data group needs to be determined, the voltage jump data in any one of the to-be-processed data groups can be used as the voltage jump data in the current to-be-processed data group to be processed, and one of the to-be-processed data groups can be used as the current to-be-processed data group to be explained. The voltage jump data refers to voltage fluctuation data of the ammeter, and voltage fluctuation values at two adjacent moments can be used as the voltage jump data. The preset jump data threshold is a preset voltage fluctuation data threshold, and may be 1V or 2V. The transition point in time can be understood as the point in time at which the amplitude of the voltage ripple exceeds a threshold value. The data hop-set may include a plurality of hop-instants.
Specifically, the fluctuation range of the voltage at the current time and the fluctuation range of the voltage at the previous time in the current data group to be processed, that is, the voltage jump data, may be extracted by using an algorithm, and then the voltage jump data may be compared with a preset jump data threshold by using the algorithm, and if the voltage jump data exceeds the preset jump data threshold, the current time corresponding to the voltage jump data may be used as the jump time in the data jump set. For example, the preset jump data threshold is 3V, the voltage fluctuation range of the time 1 relative to the previous time 2 is 8V, and at this time, 8V > 3V, the time 1 can be taken as the jump time. The function of recording voltage jump data can be added to the electric meter, and when the region to which the electric meter belongs needs to be identified, the voltage jump data and the corresponding jump time in the electric meter can be called by using the interface. Correspondingly, a plurality of jump moments corresponding to the current data group to be processed, namely a data jump set, can be obtained.
It should be noted that, voltage jump data of two adjacent moments in the current data group to be processed are determined, jump moments at which the voltage jump data are greater than a preset jump data threshold are recorded, a data jump set corresponding to the current data group to be processed is obtained, a difference value between a voltage value acquired at the current moment and a voltage value at the previous moment can be calculated, and if the difference value is greater than the preset jump data threshold, the current moment can be used as a jump moment.
It should also be noted that the dynamic range is increased in order to provide a larger ripple voltage swing. The preset transition data threshold may include a positive threshold and a negative threshold. Optionally, the positive threshold may be selected to be positive 3-5V according to the situation, and the negative threshold may be selected to be negative 3-5V according to the situation. The preset jump data threshold value can also be determined by technicians according to actual working conditions.
Optionally, the determining voltage jump data of two adjacent moments in the current data group to be processed and recording jump moments at which the voltage jump data is greater than a preset jump data threshold to obtain a data jump set corresponding to the current data group to be processed includes: calculating a voltage difference value of two adjacent moments as the voltage jump data; if the voltage jump data is not within the preset jump data threshold value range, determining the later moment in the two adjacent moments as the jump moment; and determining a data hopping set of the current data group to be processed based on each hopping moment.
It should be noted that, for the voltage value corresponding to each time in the current data group to be processed, an algorithm may be used to calculate a difference between the voltage value acquired at the current time and the voltage value at the previous time, and the difference may be used as voltage jump data, and then the difference may be compared with a preset jump data threshold by using the algorithm, and optionally, the preset jump data threshold may be positive 3-5V or negative 3-5V. Further, if the difference is greater than the positive threshold or less than the negative threshold, if the voltage jump data is negative 8V, it indicates that the voltage jump data is not within the preset jump data threshold range, and the current time may be recorded as the jump time. The current time at this time is also the latter of the two times at which the comparison is made. Correspondingly, a plurality of jump moments can be obtained, the jump moments can be integrated by utilizing an algorithm to generate a data jump set, and for example, the data jump set of the ammeter A can be marked as { t }1,t2,...,tnWhere t is1May represent a first voltage transition time in meter a, and n may be an integer greater than or equal to 1.
Specifically, the voltage difference between two adjacent moments can be calculated by using an algorithm, so that a plurality of voltage jump data can be obtained, each voltage jump data can be compared with a preset jump data threshold value by using the algorithm, and if the voltage jump data is not within the preset jump data threshold value range, the later moment of the two adjacent moments can be used as the jump moment. And if the voltage difference value is not within the preset jump data threshold range, the later moment of the two adjacent moments can be used as the jump moment. Accordingly, a plurality of hopping moments can be obtained, a data hopping set of the current data group to be processed can be considered to be obtained, and a plurality of data hopping sets can be obtained correspondingly. Therefore, the district to which the ammeter belongs can be divided according to the set division standard based on the time when the voltage jump data corresponding to each ammeter exceeds the threshold value, namely the jump time, and the accuracy of determining the district to which the ammeter belongs is improved.
S130, determining the similarity among the data hopping sets, and determining the electric meter groups belonging to the same region according to the similarity.
Wherein, the similarity can be used to characterize the similarity of the jump time. The electric meter group comprises a plurality of to-be-processed electric meters belonging to the same region, namely, the plurality of to-be-processed electric meters belonging to the same region can be used as one electric meter group.
In this embodiment, the similarity between the data transition sets may be calculated, for example, the corresponding similarity between every two data transition sets may be calculated by using an algorithm, for example, the voltage fluctuation of the electric meter a exceeds the threshold time set, that is, the data transition set is { t } t1,t2,...,tnThe data jump set of the ammeter B is { t }1,t2,...,tmAnd h, wherein m and n are integers greater than or equal to 1. The number of consistent jump moments in the two sets can be calculated by utilizing an algorithm, and further the similarity degree, namely the similarity degree, between the two sets can be calculated based on the number of consistent jump moments. Accordingly, the similarity between every two data hopping sets can be calculated. Further, based on the similarity, the data hopping sets can be clustered by using a clustering algorithm, information of a plurality of clusters can be obtained, correspondingly, electric meters corresponding to the data hopping sets in the same cluster can be classified into electric meters of the same region, and correspondingly, electric meter groups corresponding to the plurality of regions can be obtained.
It should be noted that, in order to improve the calculation efficiency and avoid redundancy of calculation, when determining the similarity between each data hopping set and determining the electricity meter group belonging to the same distribution area according to the similarity, one data hopping set a in each data hopping set may be used as a calculation starting calculation standard, the similarity between the remaining data hopping set and the data hopping set may be calculated, and after the similarity between the remaining data hopping set and the data hopping set is calculated, the evaluation of the data hopping set a may be considered to be finished. It should be further noted that the similarity between each two data hop sets can also be calculated in parallel by using a distributed algorithm.
Optionally, the determining the similarity between the data hopping sets and determining the electric meter groups belonging to the same region according to the similarity includes: determining the similarity between the reference data hopping set and each data hopping set by taking one data hopping set as the reference data hopping set; after traversing each data hopping set, classifying the data hopping set with the similarity greater than a preset similarity threshold value and the reference data hopping set into the same class, and obtaining the ammeter group belonging to the same transformer area.
The reference data hopping set can be understood as a starting data hopping set when calculating the similarity between the data hopping sets. For example, the data hopping set a can be used as a reference data hopping set, and the similarities between a and the remaining data hopping sets can be calculated respectively. It should be noted that any one of the data hopping sets can be used as a reference data hopping set to process, so that the similarity between every two data hopping sets in each data hopping set can be calculated, and it is ensured that the calculation is not repeated and not omitted. The preset similarity threshold may be a preset, similarity value, and optionally, the preset similarity threshold may be a positive number close to and less than 1, for example, 0.95.
It should be noted that one of the data hopping sets may be used as a reference data hopping set, and then an algorithm may be used to calculate the similarity between the reference data hopping set and each of the other data hopping sets, and then the similarity may be compared with a preset similarity threshold value by using the algorithm, if the similarity is greater than the preset similarity threshold value, the data hopping set corresponding to the similarity and the reference data hopping set may be classified as the same, that is, the electric meters corresponding to the two data hopping sets may also be considered to belong to the same station area. For example, when the similarity γ between the electric meter a and the electric meter B is greater than or equal to the preset similarity threshold δ, it may be determined that the electric meter a and the electric meter B belong to the same region, and the calculation formula may be as follows:
it should be noted that, the platform area clustering device may also be used to perform similarity calculation once on the data jump sets of every two electric meters, and the operation is repeated in a cycle until all the electric meters are evaluated and calculated at least once, and further, each electric meter group and the corresponding platform area may be displayed on the device after being integrated by using an algorithm.
Specifically, one of the data hopping sets may be used as a reference data hopping set, and then the similarity between the reference data hopping set and each of the other data hopping sets may be calculated by using an algorithm, and after traversing each of the other data hopping sets, the data hopping set with the similarity greater than a preset similarity threshold may be classified as the reference data hopping set, that is, the electricity meters corresponding to the data hopping set and the reference data hopping set may belong to the same station area, and accordingly, the electricity meter group belonging to the same station area may be obtained.
It should be noted that, the similarity between the reference data hopping set and each data hopping set is determined, the number of consistent hopping times in each two data hopping sets can be calculated, and correspondingly, the similarity between the two data hopping sets can be calculated based on the number of consistent hopping times.
Optionally, the determining the similarity between the reference data hopping set and each data hopping set includes: determining the intersection and union of the current data hopping set and the reference data hopping set aiming at each data hopping set; and determining the similarity between the reference jump data and the current jump data set according to the number of elements corresponding to the intersection and the number of elements corresponding to the union.
It should be noted that, when the similarity between each data hopping set and the reference data hopping set needs to be determined, the similarity between any data hopping set and the reference data hopping set can be determined as the similarity between the current data hopping set and the reference data hopping set, and one of the data hopping sets is taken as the current data hopping set to be described.
Specifically, an intersection and a union corresponding to the jump time in the current data jump set and the reference data jump set may be calculated by using an algorithm, and then, the corresponding similarity may be determined based on the intersection and the union. For example, the data hopping set A of the electricity meter 1 is { t }1,t2,...,tnThe data hopping set B of the ammeter 2 is { t }1,t2,...,tmAnd h, wherein m and n are integers greater than or equal to 1. Let α be a number of elements C in the set C after intersection of the set a and the set B ═ a ∞ B; the number of elements D in the set D after the set a and the set B are merged can be written as β; it can be noted that gamma is a similarity value of the regions to which the electric meters 1 and 2 belong,
after the similarity gamma is calculated, whether the gamma is larger than or equal to a preset similarity threshold value delta is determined, and if the gamma is larger than or equal to the delta, the electric meters 1 and 2 can be judged to belong to the same distribution area.
S140, if the electric meters to be processed in the electric meter group comprise the station area identification, the station area identification is used as a target station area of the electric meter group.
The station area identifier may be understood as unique identification information corresponding to the station area, may be a tag, or may be any information that can represent the unique identifier of the station area. Based on the marked district identification in the electricity meter, it can be determined to which district the electricity meter belongs. The target region refers to region information to which the ammeter belongs.
In this embodiment, whether the electric meters to be processed in the electric meter group have the preset zone identifiers or not may be detected by using an algorithm, and if the zone identifiers exist, the zone identifiers may be used as the zone identifiers of the zones to which the electric meters to be processed belong in the electric meter group, that is, may also be used as the target zone of the electric meter group.
Optionally, if the to-be-processed electricity meters in the electricity meter group include a station area identifier, identifying the station area as a target station area of the electricity meter group, including: and if one to-be-processed electric meter comprising the station area identification exists in the electric meter group, taking the station area identification as a target station area of the electric meter group.
It should be noted that, if there is a meter to be processed in the meter group that includes the station area identifier, the station area identifier may be used as the target station area of the meter group.
It should be further noted that, if more than one to-be-processed electric meters including the station area identifier exist in the electric meter group, and the station area identifiers are different, it may be indicated that at least two to-be-processed electric meters exist in the electric meter group and may not belong to the same station area, at this time, the to-be-processed array of the to-be-processed electric meters may be re-collected, and the station area corresponding to each to-be-processed electric meter may be re-determined.
It should be further noted that, if there is no to-be-processed electric meter including the station area identifier in the electric meter group, it may be stated that which station area each to-be-processed electric meter in the electric meter group belongs to cannot be determined according to the station area identifier, and at this time, the to-be-processed array of the to-be-processed electric meters may also be re-collected, and the station area corresponding to each to-be-processed electric meter may be re-determined.
Optionally, if at least one to-be-processed electric meter including a station area identifier exists in the electric meter group, and the station area identifiers are different, re-collecting the to-be-processed arrays of the to-be-processed electric meters in the electric meter group; or, if the electric meter group does not have the electric meters to be processed including the station area identification, re-collecting the array to be processed of each electric meter to be processed in the electric meter group; and repeatedly executing and determining voltage jump data of two adjacent moments in the current data group to be processed based on the re-collected data group to be processed, determining a data jump set, and determining a target station area based on the data jump set.
Specifically, in order to improve the accuracy of determining the region to which the electric meter belongs, the electric meters to be processed including the region identifier in the electric meter group can be counted by using an algorithm, and if the electric meter group includes the region identifier and the number of the electric meters to be processed with different region identifiers is greater than 1, the array to be processed of each electric meter to be processed in the electric meter group can be collected again; if the number of the to-be-processed electric meters including the station area identifier in the electric meter group is 0, that is, the to-be-processed electric meters including the station area identifier do not exist in the electric meter group, the to-be-processed array of each to-be-processed electric meter in the electric meter group can also be collected again.

Optionally, α may be denoted as a ═ B of the number of elements C in the set C after the intersection of the set a and the set B;
the number of elements D in the set D after the set a and the set B are merged can be written as β;
it can be noted that gamma is a similarity value of the regions to which the electric meters 1 and 2 belong,
further, when γ is equal to or greater than the threshold δ (δ is a positive number close to and less than 1, such as 0.95), it is determined that the electric meter 1 and the electric meter 2 belong to the same station, that is:
further, the platform area identification device can perform platform area division evaluation on every two pieces of intelligent electric meter data, and the platform area identification device can perform cyclic reciprocating until all the electric meters are evaluated at least once, and platform area division results can be displayed on the device after integration.
