In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 is the indicative flowchart of the electrical energy meter fault Forecasting Methodology of an embodiment;As shown in figure 1, in the present embodiment
Electrical energy meter fault Forecasting Methodology include step:
S11, obtains the real-time running data of electric energy meter, and the real-time running data is input into default breakdown judge mould
Type, judges whether to break down;
In one embodiment, be able to can also be collected by the service data of power information acquisition system Real-time Collection electric energy meter
The service data that electric energy meter is reported automatically in the process of running.Electric energy meter has self-checking function, can be by own hardware loop pair
The operating mode of each module is detected and is carried out reporting events, and such failure mainly has:On-load switch malfunction or tripping;ESAM is wrong
By mistake;Internal memory card initialization mistake;Clock battery voltage is low;Internal processes mistake;Holder failure or damage;Clock failure;Stop
Electricity is checked meter battery undervoltage.

Barrier information mainly has:Power cut-off recording battery undervoltage;Have a power failure;Switching on;Switch access state quantitative change position;Game clock lid;Open end button cover;
Disturb stationary magnetic field;Reset.
Additionally, for the event of failure according to electric energy meter or terminal to report, corresponding fault message can be stored in described
Historical failure data storehouse.In historical failure data storehouse, the reporting events record of electric energy meter can be formed directly in fault message, and measure
The information such as amount, switching value are then according to corresponding breakdown judge pattern-recognition.
5) fault message in historical failure data storehouse is sorted out, is formedImplications, X is fault message
Set F={ F1, F2..., FNItem or item collection, Y be failure predication results set R={ R1, R2..., RNItem or item collection.
Wherein, sort out according to and step 4) in it is identical.
6) minimum support and confidence level of setting are read, historical failure data storehouse is scanned with Apriori algorithm and is searched
Rope frequent item set simultaneously extracts correlation rule.Idiographic flow is as follows:
In the implications set that first stage must be formed from step 5, all high frequency project team are found out.If support is more than
During equal to set minimum support threshold value, high frequency k- project team is set to, is typically expressed as Largek.Algorithm and from
Produce Largek+1 again in the project team of Largek, until cannot again find longer high frequency project team untill.Second stage exists
It is pass by this rule extraction when the confidence level that a rule is tried to achieve meets min confidence under the condition threshold of min confidence
Connection rule.Wherein, high frequency project team refers to that the frequency that a certain project team occurs is higher for all items.
7) after the completion of correlation rule is extracted, the fault diagnosis mining model of electric energy meter is formed, the fault diagnosis is excavated

Module, was additionally operable to before the service data is input into default breakdown judge model, and pre- place is carried out to the service data
Reason, removes noise data therein;
And/or,
Default breakdown judge model includes:Fly away and stop walking event with mutation failure judgment models, clock failure judgment models, indicating value
In barrier judgment models at least two.
10. electrical energy meter fault prediction meanss according to claim 8 or 9, it is characterised in that also include:
Fault diagnosis mining model builds module, for the failure letter in the historical failure data storehouse to the default electric energy meter
Breath is sorted out, and is formedImplications, X be fault message set F={ F1, F2..., FNIn item or item collection, Y is
Failure predication results set R={ R1, R2..., RNIn item or item collection;Read default minimum support and confidence level, root
The implications set in the historical failure data storehouse is scanned using Apriori algorithm according to the minimum support and confidence level,
Obtain frequent item set and extract correlation rule;Mould is excavated according to the fault diagnosis that the correlation rule for extracting builds the electric energy meter
Type;
Wherein, a plurality of historical failure information and each bar failure letter of the electric energy meter are stored in the historical failure data storehouse
Cease corresponding failure predication result.
