Problems solved by technology

At present, there is a lack of software tools for calculating the measurement accuracy in China, and there are accuracy calculators or some automatic calculation methods for measurement values ​​abroad, but these methods still cannot be migrated to high-speed fluid flow measurement scenarios, and have not actually opened up the entire calculation process. Doesn't really automate accuracy assessment

Abstract

The invention discloses an automatic evaluation method and device for high-speed fluid flow measurement accuracy and a storage medium. The method comprises the following steps that data of fluid flow in a pipeline are obtained; cleaning the data by adopting a data cleaning algorithm of an isolated forest; carrying out uncertainty calculation on the cleaned data to obtain total synthesis standard uncertainty; and outputting an accuracy evaluation result according to the total synthesis standard uncertainty. According to the method, a whole process scheme from measurement data collection to accuracy result output is provided, the intervention degree of a user is reduced in the aspect of evaluating the high-speed fluid flow measurement accuracy, the workload of related personnel is relieved to a certain extent, the user only needs to pay attention to the final result, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the field of industrial production monitoring, in particular to a method, a device and a storage medium for automatically evaluating the accuracy of high-speed fluid flow measurement. technical background [0002] In the industrial production scene and scientific research experiment scene, there are many demands for high-speed fluid flow measurement in confined spaces (such as pipelines). At present, indirect methods such as differential pressure measurement and velocity measurement are often used to obtain the current state of space fluid, so as to calculate the fluid flow. In addition, for example, the air flow rate has been directly obtained by electronic measuring equipment such as air flow meter. As the main tool for measuring fluid flow at present, flowmeter plays an important role in measuring the flow of various fluids in a closed pipeline. In view of many methods of flow measurement, different calculation methods and differ...
