Embodiment Construction

[0028] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a method for analyzing the accuracy of an electric energy meter cover opening event includes the following steps:

[0030] 1) The latest event of opening the cover of the smart watch is called once a month;

[0031] 2) Judging whether the opening time of the electric energy meter is more than K1 days later than the installation time of the electric energy meter, if so, add the N times of opening the meter cover before the test call, until the data of the last test call;

[0032] T kg -T az >K1; K1 takes 1;

[0033] In the above formula: T kg is the opening time;

[0034] T az is the installation time;

[0035] 3) Process the unanalyzed cover opening records to determine whether the event of opening the cover of the electric energy meter meets the conditions: the opening time and closing time ...

Abstract

The invention provides a method for analyzing open-case event accuracy of an electric energy meter, and the method relates to the field of metering. The method aims to solve the problems that the electric energy meter open-case event record is not very accurate, and a failure of erroneous judgment of open-case record exists. The method comprises the steps of: 1) interrogating a last-time open-caseevent of an intelligent meter once a month; 2) judging whether open-case time of the electric energy meter is K1 days later than installation time of the electric energy meter, and if so, increasingN times of open-case events before interrogation until reaching data interrogated last time; 3) processing unanalyzed open-case events, and judging whether the open-case events of the electric energymeter meet a condition; 4) further screening the open-case events of the electric energy meter satisfying the condition in the step 3); 5) and performing accuracy judgment on the open-case events of the electric energy meter according to a anomaly generation situation. The method is used for further analyzing the open-case events of the electric energy meter from various aspects, and improves theopen-case event accuracy of electric energy meter.

Description

technical field [0001] The invention relates to the field of metering, in particular to a method for analyzing the accuracy of an electric energy meter cover opening event. Background technique [0002] At present, the smart energy meter can monitor and record the event of opening the cover in real time. Once an abnormal situation is found, the energy meter will immediately record and save the time of the event and the electricity data at the time of occurrence, and send the abnormal information through remote communication when necessary. sent to the master system. However, the record of the event of opening the cover of the electric energy meter is not very accurate. For example, the fault that the cover of the meter was not tightly closed before leaving the factory was misjudged by the system as a faulty meter with a record of opening the cover. Zhejiang Electric Power Company's electricity consumption information collection system has a total of 4,361 records of electri...
