双传感器测量系统故障的在线探测与诊断

On-Line Trouble Detection and Diagnosis of Double Transmitter Measure System

本文试图建立一套完整的双传感器测量系统故障的在线探测与诊断理论,以便指导相应的系统设计和工程应用,为此提出了探测变量和诊断判据的新概念以及一套鉴别公式,并给出了测量系统故障诊断原理及诊断设定值的选取方法。

In this paper, an on- line detection and diagnosis theory of double - transmitter measure system is tried to create in order to guide the relevant system design and engineering application, new concepts of detective variable and of diagnostic criterion as well as a set of criterion equations arc put forward. And the principle of measure system trouble diagnosis and the determination method of diagnostic sctpoint values arc given.
