Real-time vibration alarm system for helicopter health monitoring

Abstract

The invention provides a real-time vibration alarm system for helicopter health monitoring, which comprises a vibration monitoring subsystem. The vibration monitoring subsystem comprises a monitoring processor, a vibration alarm assembly and a plurality of first vibration sensors, and the first vibration sensors collect first vibration signals of a helicopter in real time and send the first vibration signals to the monitoring processor. The vibration monitoring subsystem is bidirectionally connected with a flight parameter recording subsystem through a bus, the flight parameter recording subsystem comprises a flight parameter acquisition recorder and a plurality of second vibration sensors, and the second vibration sensors acquire second vibration signals of the helicopter in real time and send the second vibration signals to the monitoring processor. The monitoring processor forms and outputs an alarm signal based on the first vibration signal, the second vibration signal and a vibration alarm judgment condition, and the vibration alarm assembly executes the alarm signal and feeds back an alarm execution result to the monitoring processor. The alarm system has the advantages of high integration level, high reliability, low false alarm rate and the like, and can ensure the flight safety of the helicopter.

Description

technical field [0001] The invention belongs to the field of avionics and relates to the design technology of a real-time vibration warning system, in particular to a real-time vibration warning system for helicopter health monitoring. Background technique [0002] With the development of vibration monitoring technology and flight parameter acquisition and recording technology, health monitoring technology and flight parameter acquisition and recording technology have been widely used in helicopter health monitoring, but the current vibration warning system of helicopters has low integration and unbalanced computing load And only supports offline monitoring, high false alarm rate and other deficiencies. [0003] Therefore, it is necessary to improve the vibration warning system for helicopter health monitoring. Contents of the invention [0004] The purpose of the present invention is to design a real-time vibration alarm system for helicopter health monitoring, which use...
