Problems solved by technology
[0003] In the process of realizing the present invention, the inventor found that: the current rotation cycle of the smart energy meter is fixed, that is, after a fixed period of time, the rotation of the smart energy meter is performed once; however, for the smart energy meters produced by different manufacturers The degree of mechanical wear and the aging degree of electronic components of smart meters working in different regions are not the same. It is not pertinent to adopt a fixed rotation cycle for all smart meters, which is likely to make many Most of the smart energy meters that are in normal operation have been removed for inspection, or a large part of the overloaded smart energy meters have not been rotated in time. It can be seen that the rotation of smart energy meters with a fixed rotation cycle is not suitable for practical applications. Provide A method for determining the rotation period of a smart energy meter suitable for practical applications has become a problem to be solved by those skilled in the art

The embodiment of the invention provides a method and a system for forecasting a rotation cycle of an intelligent electric meter. The method comprises the following steps in sequence: selecting a training sample set from fault information of a plurality of intelligent electric meters; determining the initial meal value of the rotation cycle of the intelligent electric meter produced by a manufacturer k in a region J and determining whether to update the initial weighting coefficient according to the training sample set; if so, updating the corresponding initial weighting coefficient based on the determining result, and determining the rotation cycle mean value of the intelligent electric meter produced by the manufacturer k in the region J; and if not, defining the initial mean value to be the rotation cycle mean value of the intelligent electric meter produced by the manufacturer k in the region J. By adopting the embodiment of the invention, the rotation cycle of the intelligent electric meter is specifically forecasted; and the method and the system are more suitable for actual application.
Description
technical field [0001] The present invention relates to the technical field of smart electric energy meters, and more particularly, to a method and system for predicting the rotation period of intelligent electric energy meters. Background technique [0002] With the prolonged use of smart energy meters, the problems of mechanical wear and aging of electronic components will occur, which often lead to inaccurate measurement of smart energy meters. In order to ensure the measurement accuracy of smart electric energy meters, the national "Power Supply Business Rules" stipulates that "power supply enterprises must verify and rotate billing electric energy meters according to the prescribed period, and conduct irregular inspections of billing electric energy meters", that is, power supply business enterprises. It is necessary to periodically remove the installed smart energy meter for periodic verification and perform the rotation of the smart energy meter. [0003] In the proc...
