Method for remote calibration of running error of intelligent water meter

Abstract

The invention relates to a method for remote calibration of a running error of an intelligent water meter. The method comprises the specific steps of (1) installing an intelligent water meter clusterto form a tree topology structure; (2) obtaining a flow conservation basic model of the intelligent water meter cluster; (3) introducing a virtual branch to dynamically correct a topology model of theintelligent water meter cluster to obtain a flow conservation algorithm model; (4) obtaining multiple water flow increment data of the intelligent water meter cluster and calculating a relative error; (5) conducting correction and uncertainty evaluation on the calculation result; and (6) obtaining an error calculation result. The method uses the principle of flow conservation and big data analysis technology to achieve a remote detection of massively on-line running intelligent water meter errors without adding standard equipment, changing the meter structure and changing the cluster topologyof the intelligent water meter.

Description

technical field [0001] The invention belongs to the field of water meter measurement, in particular to a remote calibration method for the operation error of an intelligent water meter. Background technique [0002] The accuracy of metering devices in operation has always been a hot issue that residents and State Grid Corporation are most concerned about. At present, statistical analysis methods or adding online detection equipment are usually used to realize the supervision and evaluation of the operation error of smart water meters. Although the statistical analysis method has changed the single-phase smart water meter used by residents in the past from regular rotation to random inspection, it is still the control of the overall batch; adding online monitoring equipment will definitely increase the purchase and maintenance costs of the enterprise. This method maintains Costly and limited. [0003] After searching, no published patent documents of similar technologies we...
