Self-Correction Method Research of Multi-Sensors Information Based on IEEE1451 Smart Sensor
摘要
Abstract
Aiming to the coupling problem of multi-sensors information, the paper advances a general self-correction model of multi-sensors information based on IEEE1451 standard. Firstly, based on the inherent signal characteristics of sensors,the model realizes the judgment of sensors fault and self-immunity treatment by the amplitude, variation trend of sensors output. Then it establishes a correction engine of given TEDS based on interpolation decoupling principle of multi-sensors information, the correction engine realizes the decoupling correction by inputting calibration data of matrix form into TEDS. The experiment result shows that it realizes decoupling correction of multi-sensors information and improves measurement accuracy by decoupling correction engine of TEDS, and it can improve reliability of self-correction by using sensors self-assessment technology before decoupling correction.关键词
