Portable helicopter flight obstacle alarm system and method

Abstract

The invention discloses a portable helicopter flight obstacle alarm system and method, the system comprises a navigation device and a mobile terminal, and the navigation device comprises a power supply module, a sensor module and a data fusion processing module; the sensor module comprises an atmosphere module, a GNSS module, an optical fiber heading and attitude module and an ADS-B module; the sensor module is connected with the input end of the data fusion processing module and used for collecting helicopter flight data and transmitting the helicopter flight data to the data fusion processing module. The output end of the data fusion processing module is in communication connection with the mobile terminal, and the data fusion processing module is used for performing fusion processing onthe helicopter flight data to obtain helicopter flight fusion data and transmitting the helicopter flight fusion data to the mobile terminal; and the mobile terminal obtains helicopter flight obstacle data according to the received helicopter flight fusion data, compares the helicopter flight obstacle data with the helicopter flight fusion data to generate warning information and performs graphicand / or sound warning.

Description

technical field [0001] The invention relates to the field of aviation alarms, in particular to a portable helicopter flight obstacle alarm system and method. Background technique [0002] In the absence of any mechanical failure, the flight-into-terrain accident due to the lack of awareness of the surrounding terrain is called Controlled Flight Into Terrain (CFIT). In order to reduce CFIT accidents, a ground proximity warning system has been developed. . [0003] At present, the ground proximity warning system uses the navigation equipment cross-linked with the airborne system to collect navigation data, search for obstacle information within the set range of the aircraft according to the collected navigation data, and calculate the distance and height between the obstacle and the current aircraft Poor, and then give an alarm. However, due to the cross-linking between the existing navigation equipment and the airborne equipment, when the airborne system fails, the navigati...

AI Technical Summary

Problems solved by technology

However, due to the cross-linking between the existing navigation equipment and the airborne equipment, when the airborne system fails, the navigation equipment will be affected and cannot work normally, and the navigation data collected on the navigation equipment is relatively simple. There will be a large deviation
