Abstract

The invention discloses a calculation method and system for interference compensation of weighing results. By establishing a model and combining multiple sensor data, the problem of insufficient accuracy caused by single sensor measurement data is solved; especially for the differential pressure generated by air. Interference processing of sensors can improve the accuracy of weighing results in the production process.

Description

technical field [0001] The invention relates to the field of signal detection and processing, in particular to an interference compensation calculation method and system for weighing results. Background technique [0002] In the field of automatic control technology, in order to ensure that the requirements of the industry are met, accurate measurement is the premise to ensure the control accuracy. In modern industrial production, especially in the automated production process, various sensors are used to monitor and control various parameters in the production process, so that the equipment can work in a normal or optimal state, and the product can achieve the best quality. As an important foundation of modern information technology, sensors are the main ways and means to obtain information in the natural field. They obtain input signals from a certain attribute of the measured object, and convert them into other signals that can be easily detected according to certain rule...
