Abstract

The invention provides a pressure transmitter pressure prediction method based on a Kalman algorithm. According to the invention, the Kalman algorithm is used to evaluate the pressure acquisition value of the pressure transmitter; a weighted average filtering algorithm is combined with a Kalman algorithm, and the advantages of the weighted average filtering algorithm and the Kalman algorithm areretained on the basis of sacrificing a small amount of time; the method has the precision of the Kalman algorithm, error accumulation prevention, the accuracy of the initial value can also be improvedthrough a weighted average algorithm, the prediction accuracy is high, the parameter adjustment of the feedback Kalman filter is avoided through the prepared estimated acquisition value, the precision is very high no matter in the initial operation stage or in the middle and later operation stages, the method is simple, the practicability is high, the accumulation of errors is inhibited, and thedata processing accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of pressure prediction, in particular to a pressure prediction method for a pressure transmitter based on a Kalman algorithm that is applicable to a lot of Gaussian noise. Background technique [0002] In the prior art, during the data acquisition process of the pressure transmitter, due to the acquisition accuracy and noise interference during the acquisition process, the collected pressure data has large fluctuations, which affects the measurement stability and accuracy. How to accurately obtain stable The measured data has become an important issue in the data collection and processing of pressure transmitters. [0003] At present, the commonly used pressure transmitter acquisition data processing method usually directly collects the signal without noise suppression processing, which results in not using the mean smoothing algorithm for signal processing, but filtering by means of the most recently collec...
