Abstract

This invention is a debugging and checkout automatic system for electronic energy meters belonging to the electrician instruments industry. The invention relates to technical fields of electric automation meterage, cyber communication and automatic testing system. It suggests good solutions to errors in debugging and producing inefficiency. This invention is composed by multichannel synchronous signal conditioning and sampling cells, VXI bus controller, SPWM power output cell. The multichannel synchronous signal conditioning and sampling cell transmits the well gathered error of electronic energy meters to VXI bus controller, then, after operation, analysis and adjusting, the error will back feed to electronic energy meters; SPWM power output cell supply the power of multichannel synchronous signal conditioning and sampling cells and electronic energy meters under the control of VXI bus controller. This invention has improved the techniques level of electronic energy products producing. And high quality has boost up the market competitive capacity of this invention.

Description

technical field [0001] The invention belongs to an electric energy meter inspection device in the electric instrument and meter industry, and relates to the technical fields of electric automatic measurement, computer communication, automatic test system and the like. Background technique [0002] Traditional electric energy meter debugging and verification generally adopt manual methods. In the production process design, the debugging and verification of electric energy meters are independent of each other. Repeating the process of hanging meter wiring many times wastes manpower and time, and the debugging error is large. , Production efficiency is low, product quality is difficult to guarantee. The production of electronic watt-hour meters urgently needs a high-speed, high-reliability debugging and calibration automation system. Contents of the invention [0003] In order to overcome the defects of manual debugging and calibration of the existing electronic energy meter...
