A detection quality verification method for automatic verification system of single-phase smart electric energy meter

Abstract

The invention relates to a detection quality checking method for an automatic verification system of a single-phase intelligent electric energy meter. The steps of the verification process on the automatic assembly line verification system are as follows: (1) preparation: enter the information of the standard electric energy meter into the verification system; (2) install the meter: put the The standard electric energy meter tray is put into the binding position and the electric energy meter of the normal task is randomly mixed and flowed into the automatic verification line body; (3) binding: the assembly line server will bind the barcode number of the standard electric energy meter with the information of the tray according to the preset scheme ;⑷Test: The automatic line will execute according to the predetermined test plan; ⑸The following table: PLC will automatically identify the standard electric energy meter on the tray according to the binding information, and the standard electric energy meter will execute the process of steps ⑶, ⑷, ⑸ in a cycle; ⑹Data Processing: Export test data. The invention is scientific in design, convenient in operation, accurate and reliable, realizes periodic checking of electric energy metering devices or instruments and equipment, and can effectively ensure accurate and reliable transmission of electric energy values.

Description

Technical field [0001] The invention belongs to the field of electrical measurement and instrumentation, in particular to a detection quality verification method for a single-phase intelligent electric energy meter automatic verification system. Background technique [0002] Electricity has become an important energy source indispensable for the survival and development of human society. Almost all human activities are closely related to electricity. The electric energy meter is a direct measurement instrument for detecting electric energy usage standards.

Problems solved by technology

At present, the method of checking during the period is to use the online detection of the electric energy meter to be tested. Dozens to hundreds of detection equipment are installed on the detection line to meet the online detection requirements of a large number of electric energy meters. The detection accuracy of the multiple detection equipment itself is calibrated It has become another difficult problem to ensure the detection accuracy of electric energy meters. Because the existing equipment itself is large in size, heavy in weight and difficult to move, it is necessary to manually carry the calibration equipment to disassemble, connect, and calibrate the testing equipment, often every calibration cycle Long time, heavy manual workload and low work efficiency
