Title INS fault diagnosis software design based on virtual instrument technology
Abstract
In virtual instrument system, users can define and design a virtual function for themselves. With the development of computer technology virtual instrument is used in more and more areas.
The fault diagnosis system is a large branch of the field of test and measurement, and fault diagnosis method has become increasingly perse with the development of science and technology . The fault diagnosis of this topic is the INS fault diagnosis based on virtual instrument. This paper introduces the background 0f INS fault diagnosis at first. Then, it introduces the basic principle 0f inertial navigation, the knowledge of the virtual instrument system, the knowledge of fault diagnosis technology.
This system is part of the INS fault diagnosis system based on the virtual instrument, detailing the implementation of the virtual instrument system, using LabVIEW to design virtual instrument interface, to achieve data acquisition, processing and display in the diagnosis process. The system is pided into three parts, respectively, the password system, inertial navigation fault diagnosis system simulation, the INS data solver system.
Data solution is regard as the core content of the system, it can receive the INS data from the serial port and calculate the position of the INS and display them.
Keywords Virtual instrument ， inertial navigation ， fault diagnosis ， data solver
