Embodiment 1

[0023] see figure 1 The helicopter ground proximity warning method shown in, the helicopter ground proximity warning method provided in this embodiment includes:

[0024] Step S101 , acquiring the current flight parameter information of the helicopter, and determining the current flight altitude of the helicopter according to the flight parameter information.

[0025] In this embodiment, the flight parameter information is used to indicate the flight status of the helicopter, or the working status of various components of the helicopter during flight. For example, flight parameter information includes latitude and longitude information representing the flight position of the helicopter, radio altitude information and barometric altitude information representing the flight altitude of the helicopter, airspeed information representing the flight speed of the helicopter, and landing gear status light information representing the state of the helicopter's landing gear. The flight...

Embodiment 2

[0048] see figure 2 The helicopter ground proximity warning method shown in, the helicopter ground proximity warning method provided in this embodiment includes:

[0049] Step S201, acquiring the current flight parameter information of the helicopter, and determining the current flight altitude of the helicopter according to the flight parameter information.

[0050] In this embodiment, the flight parameters may include a first sub-parameter used to represent the current air pressure altitude change rate of the helicopter, a second sub-parameter used to represent the current radio altitude of the helicopter, and a third sub-parameter used to represent the current airspeed of the helicopter, The fourth sub-parameter used to represent the current barometric altitude of the helicopter, the fifth sub-parameter used to represent the current roll angle of the helicopter, the sixth sub-parameter used to represent the current pitch angle of the helicopter, and the seventh sub-paramet...

Embodiment 3

[0146] see Figure 4 The helicopter ground proximity warning device shown in, the helicopter ground proximity warning device provided in this embodiment includes:

[0147] The flight height determination module 301 is used to obtain the current flight parameter information of the helicopter, and determine the current flight height of the helicopter according to the flight parameter information.

[0148] The warning model determination module 302 is used to judge the model from the excessive descent rate, the excessive terrain approach rate judgment model, the height judgment model after take-off, the unsafe ground clearance judgment model, the excessive roll angle judgment model, The warning model is determined in the tail collision judgment model and the forward-looking terrain warning model.

[0149] The warning indication module 303 is configured to determine the warning parameters corresponding to the warning model according to the flight parameters, and judge whether to ...

Abstract

Embodiments of the present invention provide a helicopter ground proximity warning method and device. The helicopter ground proximity warning method includes: obtaining the current flight parameter information of the helicopter, and determining the current flight altitude of the helicopter according to the flight parameter information; Judgment model of rate, excessive terrain approach speed judgment model, height judgment model after take-off, unsafe ground clearance height judgment model, excessive roll angle judgment model, tail collision judgment model, and forward-looking terrain warning model to determine the warning model; An early warning parameter corresponding to the warning model is determined according to the flight parameters, and it is judged according to the early warning parameter whether an warning indication corresponding to the warning model needs to be issued. In this embodiment, the corresponding judgment model can be selected as the alarm model according to the flight altitude of the helicopter, so that the alarm prediction can be targeted, the data processing efficiency is improved, the calculation time is saved, and the real-time monitoring of the helicopter flight safety is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of helicopters, in particular to a method and device for helicopter ground proximity warning. Background technique [0002] Controlled Flight into Terrain (Controlled Flight into Terrain, CFIT) refers to when the aircraft does not have any mechanical failure and the crew is operating normally, the aircraft hits the ground or obstacles due to unknown terrain or unpredictable weather. , water and other complex terrain accidents. Controlled flight into terrain accidents are one of the main causes of aircraft damage and fatalities. In order to prevent accidents of controlled flight into terrain, fixed-wing aircraft took the lead in using the ground proximity warning system to judge whether the aircraft is in a dangerous area; when the aircraft is at risk of collision, the ground proximity warning system can promptly report to the crew The personnel provide warnings to avoid accidents ...
