Embodiment Construction

[0020] The invention will be further described in detail below in conjunction with specific embodiments.

[0021] A method for evaluating the performance of an inspection device based on an electric energy meter inspection record, specifically comprising the following steps.

[0022] (1) Set up the inspection record storage area in the electric energy meter. After each electric energy meter inspection is completed, the inspection record Y is generated according to the relevant information and recorded in the inspection record storage area of ​​the electric energy meter. Y={C, MC,E ,T}, where C is the inspection agency code, MC is the serial number of the inspection device, T is the completion time of the inspection, E is the inspection error data sequence, where the inspection error data sequence E={E i}, i=1~n, E i Represents the error value of a certain detection point i, and n represents the number of detection points.

[0023] The detection point i is generally selected ...

Abstract

The invention relates to an inspection device performance evaluation method based on an electric energy meter inspection record. The method comprises the following steps of firstly, collecting data in the inspection of an electric energy meter, and secondly, selecting time or batch range to carry out performance analysis. According to the present invention, an inspection record storage area is specially planned in the electric energy meter and is used for storing the inspection records, so that the traceability management of the inspection records of the electric energy meter can be achieved; the performance analysis of the inspection device of the electric energy meter is achieved through the error inspection records of the electric energy meter, when the inspection device with problems is found, the devices of the previous suppliers or departments are evaluated, so that the metering fairness is ensured.

Description

technical field [0001] The invention relates to a performance evaluation method of an electric energy meter inspection device. Background technique [0002] The electric energy meter is a product for measuring and measuring the invisible and intangible "electricity". As a kind of electric energy measuring instrument, its measurement reliability directly affects the fairness of charging. Therefore, the country regards the electric energy meter as a product of compulsory metering supervision, implements the traceability management of the inspection device, and adopts measures such as full acceptance inspection and operation sampling inspection for the electric energy meter. During the life cycle of an electric energy meter, it involves the inspection of the electric energy meter factory, the inspection device manufacturer, the provincial metering center and the random inspection of the Technical Supervision Bureau. [0003] The error inspection of the electric energy meter wi...
