Problems solved by technology

The electric meter is very easily affected by the external environment or improper human operation, so it is essential to do a good job of calibrating the electric meter. However, most of the existing technologies require manual calibration, which requires a large workload and takes a long time. At the same time The error rate is also relatively large, and in the process of continuous development of the power system, people have put forward higher requirements for the calibration of electric meters

Embodiment 1

[0045] Smart meters are an important part of building a smart grid and belong to the smart terminals of smart grids. The accuracy of the equipment directly affects the accuracy of the measurement value. In actual measurement work, the surrounding environmental factors may affect the accuracy of the measurement. In the process of maintenance, the overall quality of maintenance personnel will also have a certain impact on the quality of measurement, and the calibration time of smart meters is too long, the efficiency is low, and there is also a large error rate. To this end, the embodiment of the present invention discloses a fast verification method for a smart meter, such as figure 1 shown, including the following steps:

[0046] Push the smart meter to be tested to the calibration table through the transmission device to obtain the circuit information of the smart meter to be tested;

[0047]Based on the circuit information, the standard parameter information of the smart me...

Embodiment 2

[0065] This embodiment discloses a quick verification system for a smart meter, such as figure 2 As shown, it includes: an acquisition module, a determination module, a self-check module, a calculation module, and a repeat check module, and the modules are connected in sequence;

[0066] The acquisition module pushes the smart meter to be tested to the calibration table through the transmission device to acquire circuit information of the smart meter to be tested;

[0067] The determining module, based on the circuit information, determines the standard parameter information of the smart meter to be tested;

[0068] The self-checking module is used to control the calibration bench to perform a power-on operation on the smart meter to be tested, and to perform a self-check of the smart meter to be tested under a stable voltage and current;

[0069] The calculation module is used to obtain the actual circuit information of the smart meter to be tested, compare it with the stan...

Abstract

The invention discloses a rapid verification method and system for an intelligent electric meter and a storable medium, and relates to the technical field of intelligent electric meter detection, and the method comprises the steps: pushing a to-be-detected intelligent electric meter to a verification platform through a transmission device, and obtaining the circuit information of the to-be-detected intelligent electric meter; based on the circuit information, determining standard parameter information of the to-be-tested intelligent electric meter; controlling a verification table to carry out power-on operation on the to-be-tested intelligent electric meter, and carrying out self-inspection on the to-be-tested intelligent electric meter under stable voltage and current; acquiring actual circuit information of the intelligent electric meter to be tested, comparing the actual circuit information with the standard parameter information, and calculating a difference value between the actual circuit information and the labeled parameter information; and adjusting an ammeter compensation coefficient based on the difference value, and sending a verification instruction to the to-be-tested intelligent ammeter again until verification is completed. According to the technical scheme, the maintenance efficiency of the intelligent electric meter can be improved, the human input of maintenance personnel is reduced, and the overall working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of smart meter detection, and more particularly, to a method, a system and a storage medium for fast verification of a smart meter. Background technique [0002] With the gradual scarcity of global resources, increasing environmental pressure, and the deepening of the process of electricity marketization, the development of traditional power networks has encountered many practical problems. With the increasing number of distributed energy sources connected to the grid, people's requirements for power quality are also increasing year by year, and smart grids emerge as the times require. [0003] The smart meter is an important data acquisition device for the smart grid. In addition to the basic electricity metering function of the traditional electricity meter, in order to adapt to the use of smart grids and new energy, it also has electricity consumption information storage, two-way multi-rate metering Smar...
