An error calibration method suitable for different meters

Abstract

The invention relates to the technical field of meter calibration and especially relates to an error calibration method suitable for different meters. The method comprises the following steps: S1) establishing communication connection between a meter to be calibrated and a calibration device; S2) sending a query command by the calibration device to the meter to be calibrated to obtain calibrationinformation of the meter to be calibrated, matching the calibration information with the type in a database to obtain a corresponding configuration file; and S3) carrying out calibration on the meterto be calibrated according to the configuration file. By sending the query command by the calibration device to the meter to be calibrated to obtain the calibration information of the meter to be calibrated, matching the calibration information with the type in the database to obtain the corresponding configuration file, and finally, carrying out calibration on the meter to be calibrated accordingto the configuration file, automatic calibration of different meters is realized without manual selection of the calibration scheme, thereby improving calibration accuracy and efficiency.

Description

technical field [0001] The invention relates to the technical field of meter calibration, in particular to an error calibration method suitable for different meters. Background technique [0002] Instrument verification is an important part of instrument production. The current methods of calibrating instruments are generally divided into: 1. Realize measurement error calibration by replacing mechanical parts such as calibration gears; 2. Realize measurement error calibration through software correction. [0003] For instruments that need to replace calibration gears or other mechanical parts to achieve calibration, they have been gradually replaced by smart instruments. For smart meters that use software parameter configuration to achieve error calibration, due to different connection methods, different application layer communication protocols, different meter specifications, and different meter calibration strategies, human intervention and human selection are required w...

Problems solved by technology

For smart meters that use software parameter configuration to achieve error calibration, due to different connection methods, different application layer communication protocols, different meter specifications, and different meter calibration strategies, human intervention and human selection are required when calibrating different meters to be calibrated Appropriate meter calibration scheme, so as to meet the mutual matching of application layer communication protocols, the selected flow point is appropriate, and the error regulation setting is reasonable, but this operation greatly increases the possibility of human error, and does not realize one-button intelligent calibration
