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

Abstract

The invention discloses a portable helicopter flight obstacle alarm system and method, wherein the system includes a navigation device and a mobile terminal, the navigation device includes a power supply module, a sensor module and a data fusion processing module; the sensor module includes an atmospheric module, a GNSS module, an optical fiber aviation module Attitude module and ADS‑B module; the sensor module is connected to the input end of the data fusion processing module to collect helicopter flight data and transmit it to the data fusion processing module; the output end of the data fusion processing module is connected to the mobile terminal for communication The helicopter flight data is fused to obtain the helicopter flight fusion data, and the helicopter flight fusion data is transmitted to the mobile terminal; the mobile terminal obtains the helicopter flight obstacle data according to the received helicopter flight fusion data. Contrast, generate alerts and provide graphical and / or audible alerts.

Description

technical field [0001] The invention relates to the field of aviation alarm, in particular to a portable helicopter flight obstacle alarm system and method. Background technique [0002] In the absence of any mechanical failure, the aircraft's flight into the terrain accident due to 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 was developed. . [0003] At present, the ground proximity warning system uses the navigation equipment that is connected with the airborne system to collect navigation data, searches for the obstacle information within the set range of the aircraft according to the collected navigation data, and calculates the distance and height between the obstacle and the current aircraft. bad, and then give an alarm. However, because the existing navigation equipment is connected with the airborne equipment, when the airborne system fails, the na...
