Online metering device and method for automatically determining misalignment

Abstract

The invention relates to an online metering device and method for automatically determining misalignment, and the device comprises a sensor A, a sensor B, an analog-to-digital converter, a single chipmicrocomputer and a display operation touch screen, wherein the sensor A and the sensor B are used for detecting the same physical quantity and are both connected to the analog-to-digital converter,the analog-to-digital converter is connected to the single chip microcomputer that is connected to the display operation touch screen, the single chip microcomputer stores a control program for judging whether the sensor is out of alignment, the display operation touch screen is used for displaying the measurement result of the sensor A or the sensor B, and the interaction between the human and the control program in the single chip microcomputer is realized by the display operation touch screen. The technical solution effectively solves the technical problem that the existing sensor cannot automatically determine the misalignment online, fills the technical blank, promptly issues an alarm when the sensor is out of alignment to avoid related losses, and can be used continuously for a longtime at the same time under the premise that the sensor is not out of alignment to ensure the accuracy of the measurement results and improve the user's trust in the measurement results.

Description

technical field [0001] The invention relates to the technical field of on-line metering, in particular to an on-line metering device and method for automatically judging inaccuracy. Background technique [0002] The measurement sensors used in the industrial production line generally need to be dismantled and sent to the measurement technical institution for traceability of the value at regular intervals to ensure the accuracy of the measurement results and improve the user's trust in the measurement results. However, in the actual industrial production process, sometimes the measurement sensors have passed through It didn't take long for the traceability of the value to appear, and only when the produced product was unqualified or the production line failed, could the user discover the result of the measurement sensor's inaccuracy; furthermore, due to the need for continuous production , it is difficult for users to dismantle and send in time. In order to take into account ...

AI Technical Summary

Problems solved by technology

[0004] 1) If the relative installation positions of two or more identical measurement sensors are improper, the measurement results will have large deviations, which will affect the decision-making judgment of production process control;

[0005] 2) The misalignment of multiple measurement sensors is random, and it is difficult to confirm which measurement sensor has been misaligned through human judgment, so installing one measurement sensor and installing multiple measurement sensors are the same for the judgment of the misalignment subject , that is, no exact result can be obtained;

[0006] 3) When there is a quality problem in the production product, it is often necessary to check various influencing factors one by one, and it is difficult to accurately determine whether it is caused by the inaccuracy of the measuring sensor
