Operation error calibration method based on Internet of Things intelligent water meter

The invention discloses an operation error calibration method based on an Internet of Things intelligent water meter, and relates to the technical field of intelligent water meter calibration. The problems that in the prior art, an intelligent water meter calibration process is single in consideration factor, errors are large, the correction process cannot be automatically and dynamically adjusted according to the actual environment, and subjective factors of a water terminal are not considered are solved; a plurality of interference factors influencing the reading accuracy of the intelligent water meter are defined, and a single-factor test group and a composite-factor test group are respectively set to stereoscopically analyze error coefficients caused by each single factor and contribution degree in a composite scene, so that the calibration process is more diversified, and the calibration result is more accurate; in addition, coefficient re-calibration can be actively carried out according to environmenta
