Flowmeter verification method and device, computer equipment and storage medium

Abstract

The invention relates to a flowmeter verification method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the feature data of a target flowmeter, and the feature data comprises the acceleration and the flow value of the target flowmeter; determining whether the state of the target flowmeter is abnormal or not according to the feature data; if the state of the target flowmeter is abnormal, diagnosis parameters of the target flowmeter are determined according to the feature data; according to the diagnosis parameters, abnormal reasons corresponding to the diagnosis parameters are searched in a pre-established diagnosis database, and the diagnosis database comprises the mapping relation between the diagnosis parameters of the template flowmeter and the abnormal reasons. According to the method, the abnormal vibration data of the target flowmeter can be monitored and recorded in real time, and the reason of the abnormal vibration of the target flowmeter can be diagnosed in time.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a verification method, device, computer equipment and storage medium of a flowmeter. Background technique [0002] The target flow meter is an instrument used to measure the flow of fluid in the pipeline. It is used in the industrial process control environment to indicate the flow of the measured fluid and the total amount of the measured fluid within a selected time interval. For example, the target flow meter used for natural gas trade measurement and settlement, petrochemical measurement. [0003] Theoretically, the target flowmeter is installed in the pipeline and will maintain a stable vibration rhythm under normal working conditions. However, as time goes by, the target flowmeter installed in the pipeline may change its installation position, such as falling, overturning Wait. At the same time, under different working conditions, during the use of the target fl...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that during the maintenance process of the target flowmeter, it is difficult to monitor the abnormal installation status of the target flowmeter, the abnormal vibration during the use of the target flowmeter is difficult to monitor, and the cause of the abnormal vibration is difficult to determine, resulting in the failure to find the abnormal vibration of the target flowmeter in time , and it is impossible to diagnose the cause of abnormal vibration of the target flowmeter in time
