Ship integration electric power propulsion system intelligence fault diagnosis system based on LabVIEW

Abstract

A ship integration electric power propulsion system intelligence fault diagnosis system based on LabVIEW comprises an intelligent database module, a data information acquisition module, a time domainanalysis and fault characteristic extraction module, a fault identification module and a man-machine interaction interface. The intelligent database module contains a ship integration electric power propulsion system database based on SQL and the system database comprises a motor intelligent database, a sensor intelligent database, a frequency converter intelligent database, an inverter intelligent database and a propeller intelligent database. The data information acquisition module comprises a triaxial accelerometer and an FPGA module. The fault identification module comprises an off-line training portion and an on-line identification portion. The man-machine interaction interface is connected to the intelligent database module, displays data sent by the intelligent database module and sends an operation instruction to an intelligent database. The system possesses a good man-machine interaction interface, operation is simple, a diagnosis process and result display are concise and visual, and execution efficiency and fault diagnosis accuracy are high.

Description

technical field [0001] The invention belongs to the field of fault diagnosis of a ship's comprehensive electric propulsion system, in particular to an intelligent fault diagnosis system for a ship's comprehensive electric propulsion system based on LabVIEW. Background technique [0002] The ship integrated electric propulsion system refers to the propulsion method that uses electric machinery to drive the propeller to propel the ship's movement. Compared with the traditional mechanical propulsion method, the ship that uses electric propulsion has more advantages in terms of economy, vibration, noise, ship manipulation, layout, safety and reliability. etc. have obvious advantages. As one of the important components of a ship, whether it can operate normally is of great significance to the safety and security of the ship. Therefore, how to quickly and accurately diagnose and repair the faults of the ship's integrated electric propulsion system has become a major issue in ship ...

AI Technical Summary

Problems solved by technology

If relying solely on technicians to maintain the electric propulsion system, neither the rapidity of fault location nor the rapid elimination of faults can be guaranteed. Therefore, how to diagnose the faults of the ship's integrated electric propulsion system in real time, accurately and effectively is a Current Issues to be Solved

[0003] Most of the existing researches are diagnosing a single part of the ship's integrated electric propulsion system without forming an overall fault diagnosis system. The present invention has developed an intelligent fault diagnosis system for the ship's integrated electric propulsion system based on the LabVIEW platform, which has good man-machine The interactive interface is easy to operate, the diagnosis process and result display are simple and intuitive, and the execution efficiency and fault diagnosis accuracy are high, which greatly improves the fault diagnosis ability of the ship's integrated electric propulsion system
