Embodiment one

As it is shown in figure 1, a kind of multiplexing electric abnormality inspection method of the embodiment of the present invention, including:

Step S101: obtain the first user information of the ammeter to be detected of main website storage, and read the use of ammeter to be detected Electrical information and the second user profile.

The method of the embodiment of the present invention obtains to be checked by main website (marketing system of Utilities Electric Co./metering automation system) Survey the first user information (the ammeter user profile being stored in main website) of ammeter, simultaneously by infrared, RFID (Radio Frequency Identification, REID) read the most at the scene the power information of ammeter to be detected, second User profile (actual user's information of ammeter to be detected).

Wherein, user profile includes: user name, No. ID, mark etc., power information includes various types of other electricity consumption data.

Step S102: described first user information is compared with described second user profile, when described first user When information is inconsistent with described second user profile, determine that multiplexing electric abnormality occurs.

The method of the embodiment of the present invention is by internal configuration information match options, the first use of the ammeter obtained from main website Family information carries out matching degree comparison with the second user profile read from on-the-spot ammeter to be detected, thus completes data filtering, with Judge whether ammeter to be detected is correct ammeter.If two user profile are inconsistent, illustrate that ammeter to be detected is not correct Ammeter, it is determined that multiplexing electric abnormality occurs.

When described first user information is consistent with described second user profile, then perform step S103,

Step S103: calculate multiplexing electric abnormality according to default multiplexing electric abnormality suspicion index calculating method and described power information Suspicion index, it is judged that whether described multiplexing electric abnormality suspicion index is more than the threshold value preset.

The embodiment of the present invention calculates multiplexing electric abnormality suspicion index by default multiplexing electric abnormality suspicion index calculating method, And calculated multiplexing electric abnormality suspicion index compared with the threshold value preset by historical experience, thus judge whether can Multiplexing electric abnormality can be there is.

Step S104: when described multiplexing electric abnormality suspicion index is not more than the threshold value preset, determine do not occur that electricity consumption is different Often.

When multiplexing electric abnormality suspicion index is not more than the threshold value preset, illustrates not occur multiplexing electric abnormality phenomenon, therefore may be used Determine that multiplexing electric abnormality does not occur.

When described multiplexing electric abnormality suspicion index is more than the threshold value preset, perform step S105.

Step S105: after calculating the access standard electronic load of described ammeter outgoing line side to be detected, the reality in preset duration Border consumes electricity.

When multiplexing electric abnormality suspicion index is more than the threshold value preset, illustrate to there may be multiplexing electric abnormality, now can pass through Ammeter outgoing line side accesses standard electronic load, carries out step-by-step counting verification error judgment, and standard electronic load can be such as merit The load of rate 1KW.

Step S106: the theoretical electricity that consumes being supported in described preset duration by described standard electronic actual disappears with described Power consumption compares；

In this step S106, such as can be with the theoretical consumption within preset duration 1 minute of the testing standard electronic load Electricity, and access after ammeter outgoing line side the actual consumption electricity within 1 minute.

Step S107: judge whether that multiplexing electric abnormality occurs according to comparative result.

Access standard electronic load at electric supply meter outgoing line side, carry out step-by-step counting verification error judgment.According to last aobvious Show result, it may be judged whether there is multiplexing electric abnormality.

If actual consumption electricity consumes electricity equal to theory, or actual consumption electricity consumes the error of electricity with theory In allowed limits, then illustrate multiplexing electric abnormality；If actual consumption electricity is not equal to the theoretical electricity that consumes, or Actual consumption electricity and the theoretical error of electricity that consumes, outside the scope allowed, illustrate to there occurs multiplexing electric abnormality.

The embodiment of the present invention proposes a kind of multiplexing electric abnormality inspection method, and Utilities Electric Co. power utility check personnel can be helped to exist Scene quick and precisely positions multiplexing electric abnormality position, improves power utility check efficiency, greatly reduces inspection difficulty, time saving and energy saving.This Invent the equipment compared to existing investigation multiplexing electric abnormality, be possible not only to the function with verification ammeter pulse, and by meter Calculate multiplexing electric abnormality suspicion index and carry out multiplexing electric abnormality judgement such that it is able to replacing ammeter, change ammeter information, ammeter mistake Pressure, defluidization, disconnected equal multiplexing electric abnormality case are equally investigated and prosecuted, and compensate for investigating and prosecuting at present the deficiency of multiplexing electric abnormality equipment.

Embodiment two

As in figure 2 it is shown, in step S103 in embodiment one " according to default multiplexing electric abnormality suspicion index calculating method and Described power information calculates multiplexing electric abnormality suspicion index " illustrate, comprise the following steps:

Step S201: distribute corresponding index weights for the sub-information of each class in power information；Power information includes thing A class in the sub-information of part record, electricity quantum information, the sub-information of load and the sub-information of line loss or multiclass.

Preferably, power information includes at least the two sub-information of class.In the embodiment of the present invention, above-mentioned power information is carried out Classification, specifically can be divided into event class, electricity class, load class, line loss class etc., the corresponding sub-information of above-mentioned logout, electricity The sub-information of quantum information, load and the sub-information of line loss.Meanwhile, corresponding index is distributed for the sub-information of each class in power information Weight, judges multiplexing electric abnormality degree by default index.Concrete, can dislike so that the embodiment of the present invention to utilize multiplexing electric abnormality Doubt index (ELI, Electric Larceny Index) and assess the multiplexing electric abnormality degree of user, the highest then multiplexing electric abnormality of index Suspicion is bigger.Such as, ELI, in terms of full marks 100 points, can distribute event class, electricity class, load class, line loss class in the overall evaluation In index weights be respectively 40%, 40%, 10%, 10%.

Step S202: judge whether the sub-information of each class in described power information exists corresponding multiplexing electric abnormality suspicion number According to.

Owing to power information can include the sub-information of plurality of classes, therefore information sub-to every class respectively is needed to judge, Judge whether multiplexing electric abnormality suspicion data.Owing to the sub-information of every class all may comprise mass data, therefore each class letter And may incessantly there are multiplexing electric abnormality suspicion data in breath.

Step S203: when the sub-information of one type exists corresponding multiplexing electric abnormality suspicion data, different for default electricity consumption Often suspicion index increases the preset increments corresponding with multiplexing electric abnormality suspicion data, and the preset increments sum of such sub-information is not The Maximum Index value corresponding more than the index weights of such sub-information.

In the embodiment of the present invention, pre-setting multiplexing electric abnormality suspicion index, this multiplexing electric abnormality suspicion index has initial value, Typically this initial value can be set to zero, it is also possible to be set to other values.Meanwhile, the sub-information of each class it is as noted previously, as There may be more than one multiplexing electric abnormality suspicion data, therefore this preset increments is corresponding with multiplexing electric abnormality suspicion data.Such as, exist When judging whether multiplexing electric abnormality suspicion data according to electricity quantum information, can be according to the daily power consumption of n days of ammeter record E_iAnd meansigma methods AvgE judges, as the daily power consumption E of i-th day_iAnd the difference between this meansigma methods AvgE is more than one During the difference preset, then may determine that i-th day and there are multiplexing electric abnormality suspicion data, the daily power consumption E of i.e. i-th day_iCorresponding one Multiplexing electric abnormality suspicion data；Meanwhile, the daily power consumption E in i+1 sky_i+1And the difference between AvgE be likely to more than this preset Difference, then daily power consumption E_i+1Can also corresponding multiplexing electric abnormality suspicion data.Then according to above-mentioned two in step S203 Multiplexing electric abnormality suspicion data increase by two corresponding preset increments to multiplexing electric abnormality suspicion index.

Meanwhile, the preset increments sum of such sub-information is not more than the Maximum Index that the index weights of such sub-information is corresponding Value；That is, even if a certain sub-information of class exists a large amount of multiplexing electric abnormality suspicion data, can increase only according to such sub-information Electrical anomaly suspicion index is also limited, the maximum Maximum Index value corresponding less than the index weights of such sub-information.Such as, Multiplexing electric abnormality suspicion index full marks are 100, and initial value is zero, and the index weights of the sub-information (i.e. electricity quantum information) of electricity class is 40%, then the Maximum Index value that electricity information index weight is corresponding is 100 × 40%=40；If the n according to ammeter record (100=60) the daily power consumption E in sky_iAnd meansigma methods AvgE carries out judging whether multiplexing electric abnormality suspicion data, if its In the E of 25 days_iAnd the difference between this meansigma methods AvgE is more than a default difference, and each multiplexing electric abnormality suspicion data Corresponding preset increments is 2, then, after multiplexing electric abnormality suspicion index is increased preset increments, this multiplexing electric abnormality suspicion index is permissible For 0+2 × 25=50；But owing to the preset increments sum of the sub-information of each class is not more than the index weights pair of such sub-information The Maximum Index value answered, Maximum Index value corresponding to electricity information index weight is 40, therefore this multiplexing electric abnormality suspicion index is It is defined to 40 eventually.

In the embodiment of the present invention, at the preset increments determining that multiplexing electric abnormality suspicion data that the sub-information of each class exists are corresponding Add up, and increase in multiplexing electric abnormality suspicion index ELI, if the multiplexing electric abnormality suspicion index after Lei Jia is more than presetting threshold Value, then explanation power information comprises too much multiplexing electric abnormality suspicion data, therefore may determine that and there is multiplexing electric abnormality event.

The embodiment of the present invention provide a kind of multiplexing electric abnormality inspection method, preset multiplexing electric abnormality suspicion index, by Electrical information carries out classification indicator of distribution weight, determines that multiplexing electric abnormality suspicion data are the most corresponding respectively according to the sub-information of each class Preset increments, and this multiplexing electric abnormality suspicion index is increased corresponding preset increments, the multiplexing electric abnormality suspicion index after cumulative During more than predetermined threshold value, i.e. think and there may be multiplexing electric abnormality.Power information is classified also by the method for the embodiment of the present invention Indicator of distribution weight, such that it is able to carry out comprehensive analysis and judgement according to electricity, event, load and line loss information, accurately looks into Look for the user that multiplexing electric abnormality degree is higher, and greatly reduce investigation difficulty, improve the work of Utilities Electric Co. power utility check personnel Efficiency.

Preferably, as shown in above-mentioned steps S202, information sub-to every class judges respectively.Concrete, the present invention implements In example, the sub-information of logout includes decompression event, full decompression event, disconnected phase event, cutout event, defluidization event, negative phase sequence The reverse event of event, trend, current imbalance event, magnetic interference event, on-load switch misoperation event and game clock lid event In one or more.

When power information includes the sub-information of logout, step S202 " judges each class in described power information Whether information exists corresponding multiplexing electric abnormality suspicion data " specifically include:

Step A1, respectively obtain each event is corresponding in the sub-information of logout start time electricity consumption data and at the end of Carve electricity consumption data, and determine corresponding power change values；

Step A2, power change values more than predetermined power changing value time, determine that this event exists multiplexing electric abnormality suspicion Data.

Such as, the sub-information of logout comprises the relevant information of decompression event, then in step A1, i.e. may determine that mistake The electricity consumption data (such as voltage, electric current, power etc.) of the time started of pressure event, end time and start time and at the end of The electricity consumption data (voltage, electric current, power etc. can also be comprised) carved；According to start time electricity consumption data and finish time electricity consumption number According to i.e. may determine that the power change values occurred before and after this decompression event.Meanwhile, according to decompression event start time and at the end of Between may determine that the duration of decompression event, the power determined in step A2 under normal circumstances in identical duration becomes Change value (as predetermined power changing value), decompression event power change values with under normal circumstances power change values it Between difference excessive time (such as the power change values of decompression event than power change values under normal circumstances more than 20% with first-class), Then may determine that and there are multiplexing electric abnormality suspicion data, and then may determine that corresponding preset increments, and perform in step S203 right Multiplexing electric abnormality suspicion index increases the process of this preset increments.

Or, step S202 " judges whether the sub-information of each class in described power information exists corresponding electricity consumption different Often suspicion data " specifically include:

Step A3, determine the time of origin of each event in the sub-information of logout respectively, and determine the first Preset Time In section every day freeze electricity day, and the time of origin of event is positioned at the first preset time period；

Step A4, the difference freezed two continuous print days between electricity more than preset freeze electricity difference time, determine this There are multiplexing electric abnormality suspicion data in item event.

Concrete, what ammeter typically can store 62 days (two months) freezes electricity, in this logout information phase day Answer the time of origin of event within 62 days, then can perform step A3-A4.Such as, the sub-information of logout comprises decompression The relevant information of event, the time of origin of this decompression event is before ten days (i.e. within 62 days), then can obtain this decompression thing What part occurred the same day and the previous day and the most totally 3 days (the i.e. first preset time period is 3 days) freezes electricity day, is respectively E_i、E_i-1And E_i+1.At difference (the i.e. E freezed day between electricity_iWith E_i-1Between difference or E_iWith E_i+1Between difference) big In preset freeze electricity difference time, determine that this event exists multiplexing electric abnormality suspicion data.

It should be noted that when judging whether multiplexing electric abnormality suspicion data according to the sub-information of logout, permissible Only include above-mentioned steps A1-A2, it is also possible to only include step A3-A4, it is also possible to include step A1-A4 simultaneously.Different owing to occurring The change of power or power consumption generally individually can be brought during ordinary affair part, therefore by permissible to the change of power change values or the day amount of freezing Determine whether there is multiplexing electric abnormality suspicion data more accurately.

Preferably, when power information includes electricity quantum information, " judge that the sub-information of each class in described power information is No existence corresponding multiplexing electric abnormality suspicion data " including:

Step B1, determine the daily power consumption E of every day in the second preset time period_i, and determine the meansigma methods of daily power consumption AvgE；

Step B2, as AvgE and E_iBetween difference more than the first preset difference value time, determine i-th day exist multiplexing electric abnormality dislike Doubt data；Wherein, i=1,2,3 ... n, n are the natural law that the second preset time period comprises.

Concrete,It should be noted that in the embodiment of the present invention, AvgE and E_iBetween difference " AvgE-E is meant more than the first preset difference value_iMore than this first preset difference value ", or " E_i-AvgE more than this first preset poor Value ", naturally it is also possible to only selection one of which situation is as Rule of judgment, as only at " AvgE-E_iMore than this first preset Difference " time just determine and there are multiplexing electric abnormality suspicion data.Other implications represented by similar description are identical.

Or, when power information includes electricity quantum information, " whether judge the sub-information of each class in described power information There are corresponding multiplexing electric abnormality suspicion data " including:

Step B3, obtain the history daily power consumption Eh of every day in history the second preset time period same period from main website_i, and determine Meansigma methods AvgEh of history daily power consumption；

Step B4, as AvgEh and E_iBetween difference more than the second preset difference value time, determine i-th day and there is multiplexing electric abnormality Suspicion data；Wherein, i=1,2,3 ... n, n are the natural law that the second preset time period comprises.

Wherein, freeze electricity bimestrial day owing to local ammeter typically may only preserve, the daily power consumption of history same period Can be obtained by main website.By by daily power consumption E then_iWith (date as corresponding in last year, or the year before last is relatively history same period The date etc. answered) meansigma methods compare, it is also possible to determine daily power consumption E then_iThe most abnormal.Simultaneously as then The daily power consumption itself of daily power consumption and history same period both there is normal error, therefore generally, the second preset difference value More than the first above-mentioned preset difference value；It can also be provided that it is identical.

Step B5, determine slip daily power consumption meansigma methods AvgE of k days_j；

Step B6, difference between adjacent two slips daily power consumption meansigma methods of k days are more than the 3rd preset difference value Time, determine AvgE_jThere are multiplexing electric abnormality suspicion data；Wherein,J is the slip initial natural law of k days, E_i It is i-th day corresponding daily power consumption.
