Online unmanned helicopter monitoring system

Abstract

The invention provides an online unmanned helicopter monitoring system. The system comprises an airborne communication?device, a ground communication?control device, a sensor, a collector?and?an analyzer. According to the main working principle, the sensor sends original?sensing signals to the collector; the collector converts the sensing signals into electrical signals and sends the electrical signals to the analyzer; and the analyzer carries out calculation via a rapid?analysis formula to obtain a result, compares the result with a preset limit value and judges whether the result needs to be sent to the ground communication?control device via the airborne communication?device. According to the online monitoring system, the flight state of the unmanned helicopter can be mastered in real time by a ground operator, great convenience is brought to maintenance of the helicopter, a special?data?analysis way enables state information of the parts to be extracted from the background noise, the needed information is sent to the ground operator to determine the safety performances and the continuous airworthiness?ability of the unmanned helicopter according to the set procedures.

Description

technical field [0001] The invention relates to a monitoring system, in particular to an unmanned helicopter vibration on-line monitoring system, which belongs to the technical field of flight equipment monitoring. Background technique [0002] The flight control of a helicopter is mainly realized through the synergistic effect of multiple rotating parts, and these high-speed rotating parts are subjected to airflow or mechanical friction, which often generate high-frequency vibrations, which will cause rotating parts, structures and The wear and tear of electronic and electrical equipment, severe vibration will lead to catastrophic aircraft structure damage, so general helicopters are equipped with vibration monitoring devices to avoid accidents; unmanned helicopters are one of the helicopters, due to their small size , simple structure and low risk loss, so it is more and more valued and popularized by enterprises and militaries of various countries. However, since unmanned...

[0002] The flight control of a helicopter is mainly realized through the synergistic effect of multiple rotating parts, and these high-speed rotating parts are subjected to airflow or mechanical friction, which often generate high-frequency vibrations, which will cause rotating parts, structures and The wear and tear of electronic and electrical equipment, severe vibration will lead to catastrophic aircraft structure damage, so general helicopters are equipped with vibration monitoring devices to avoid accidents; unmanned helicopters are one of the helicopters, due to their small size , simple structure and low risk loss, so it is more and more valued and popularized by enterprises and militaries of various countries. However, since unmanned helicopters are remotely controlled, there are also vibration phenomena during use, and monitoring devices must be used to know the real-time status of the aircraft. , but currently there is no relevant monitoring system available in the field of unmanned helicopters, and the design structure of unmanned helicopters is quite different from ordinary helicopters, so it is necessary to design corresponding special structures for unmanned helicopters
