Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0024] A repetitive test method for an automatic verification system of a single-phase smart electric energy meter. The steps of the verification process on the automatic assembly line verification system are as follows:

[0025] ⑴Preparation: Set the standard electric energy meter of the single-phase smart electric energy meter. The accuracy of the standard electric energy meter is 0.02, while the electric energy meter used by ordinary residents, that is, the normal task electric energy meter to be tested, is level 2, and the accuracy of the standard electric energy meter is much higher For task electric energy meter;

[0026] Make a special barcode for the standard electric energy meter to distingu...

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.
