Repeatability test method applied to single-phase intelligent energy meter automated verification system

Abstract

The invention relates to a repeatability test method applied to a single-phase intelligent energy meter automated verification system. A verification process on an automated assembly line verification system comprises the steps that (1) according to preparation, standard energy meter information is input into the verification system; (2) according to loading, a standard energy meter tray is placed into an energy meter with binding position and normal tasks, and random mixing and flowing into an automated verification line body are carried out; (3) according to binding, an assembly line server binds the code number of the standard energy meter and the information of the tray according to a preset program; (4) according to test, an automatic line carries out a predetermined test scheme; (6) according to unloading, PLC automatically identifies the standard energy meter on the tray according to the bound information, and the standard energy meter tray circularly carries out the steps of (3), (4) and (5); and (6), according to data processing, verification data are exported. According to the invention, the system has the advantages of scientific design and easy operation, is accurate and reliable, carries out period verification on an energy metering device or instrument equipment, and can effectively, accurately and reliably transfer energy values.

Description

technical field [0001] The invention belongs to the fields of electric measurement and instrumentation, in particular to a repetitive test method for an automatic verification system of a single-phase intelligent electric energy meter. Background technique [0002] Electric energy has become an indispensable and important energy source for the survival and development of human society. Almost all human activities are closely related to electricity, and electric energy meters are direct measuring instruments for detecting electric energy usage standards. How to ensure the calibration of electric energy meters The accuracy and efficiency of the test, and efforts to improve the calibration efficiency of the electric energy meter have become problems that need to be solved urgently by the measurement and testing departments at all levels. [0003] In order to maintain the reliability of electric energy metering devices and test equipment, and ensure the accuracy and reliability ...

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
