Abstract

The invention discloses a water meter filtering method based on Kalman filtering. The method comprises the following steps: constructing an initial Kalman filtering model; optimizing a Q value in the initial Kalman filtering model according to a preset Q value calculation formula to obtain a first optimized Kalman filtering model; optimizing an R value in the second optimized Kalman filtering model according to a preset R value calculation formula to obtain a second optimized Erman filtering model; and filtering the collected water meter data according to the second optimized Erman filtering model. The invention further discloses a water meter filtering system based on Kalman filtering, computer equipment and a readable storage medium. By means of the water meter filtering method and device, the problems existing in an existing water meter filtering technology based on Kalman filtering can be solved, and then the measuring accuracy of the water meter is improved.

Description

technical field [0001] The present invention relates to the field of water meters, in particular to a water meter filtering method, system, computer and medium based on Kalman filtering. Background technique [0002] In data processing, the Kalman filter algorithm is often used. The parameters Q and R of the traditional Kalman filter are calculated by fixed formulas, and then continue to iteratively process the data. The filtering effect of Kalman filtering is still very significant before the data is enlarged, but if the data is enlarged, due to the fixed Q value and R value, the curve after Kalman filtering also has a small jitter. Therefore, the existing water meter filtering technology based on Kalman filtering cannot adapt to the requirements of different flow data, thereby affecting the accuracy of water meter measurement. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a water meter filtering method, syste...
