Calibration verification system and method for automated verification device of electric energy meter

Abstract

The invention discloses a calibration verification system and method for an automated verification device of an electric energy meter. The system comprises a communication module, a signal conditioning module, a measurement module and a control module; the communication module is used for being in communication with the to-be-measured automated verification device of the electric energy meter andreceiving measurement parameters output by the automated verification device of the electric energy meter; the signal conditioning module conducts signal conditioning according to the measurement parameters received by the communication module and outputs conditioning signals in a preset format; the measurement module is used for outputting a measurement result according to the conditioning signals; the control module is used for controlling the other modules in the system and outputting control signals to the to-be-measured automated verification device of the electric energy meter accordingto a preset rule; the system further comprises a wireless control module, and the wireless control module is used for sending a control instruction to the control module through a wireless communication unit of the communication module and displaying the received measurement result and measurement parameters.

Description

technical field [0001] The invention relates to the field of electric energy metering, and more specifically, relates to a calibration and verification system and method for an automatic verification device of an electric energy meter. Background technique [0002] With the development of large-scale centralized verification business of electric energy meters, automatic verification devices for electric energy meters have been widely used in my country's electric power system. However, as the standard for the verification of electric energy meters, at present, the operating status and application level of the automatic verification device for electric energy meters still lack effective and objective evaluation methods, let alone real-time monitoring of the automatic verification device for electric energy meters. The standard source cannot be calibrated remotely, and the main functions and performance of the device cannot be monitored and evaluated online. Contents of the ...
