Abstract

In this paper, we explain the fusion technology of information briefly, and discuss the general course and the merged rule about the equipment fault diagnoses by the D-S evidence theory in detail. We give the relation between basic probability assignment and matrix by the location operation of C-language, and obtain the basic probability assignment by the Matlab software which make the matrix operation easier. We diagnose the fault of the voltage transformer using the D-S evidence theory

证据理论在设备故障诊断中的应用
本文简要介绍了信息融合技术,详细讨论了D-S证据理论在设备故障诊断中的一般过程和融合规律。通过c语言的定位运算给出了基本概率赋值与矩阵的关系,并通过Matlab软件得到了基本概率赋值,使矩阵运算变得更加简单。采用D-S证据理论对电压互感器进行故障诊断
