摘　　要：针对多传感信息耦合问题,基于IEEE1451标准,提出了一种通用的多传感信息自校正模型。模型根据传感元件输出信号额定特征,从信号幅度、变化趋势等方面,实现对传感器的故障判断和自免疫处理;然后基于多传感信息插值解耦数学原理,建立了基于特定TEDS格式的校正引擎,通过将标定点数据以矩阵表格形式输入TEDS中来实现解耦校正。试验研究表明:通过TEDS解耦校正引擎,可实现对多传感耦合信息的良好校正补偿,提高检测准确度,在解耦校正的前端引入传感元件的自评估技术,可有效提高智能传感器自校正的可靠性。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.
