Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] see figure 1 with 2 , shown in the figure is a condition-triggered helicopter forward-looking prediction false alarm suppression method, which includes the following steps,

[0024] S1: Obtain the operating status information of the Helicopter Terrain Awareness and Warning System (HTAWS).

[0025] S2: Determine whether the Helicopter Terrain Awareness and Warning System (HTAWS) is currently operating normally.

[0026] S3: If the Helicopter Terrain Awareness and Warning System (HTAWS) is currently in normal operation, activate the S4 alarm suppression logic operation method to suppress false alarms.

[0027] If the Helicopter Terrain Awareness and Warning System (HTAWS) is currently not in normal operation (in the general alarm suppression state or not working), the alarm suppression logic operation method is not activated.

[0028] Wherein...

Abstract

The invention relates to a helicopter fore-sight prediction false alarm inhibition method based on condition triggering. The method comprises following steps: operation condition information of helicopter terrain awareness and warning system (HTAWS) is obtained; whether the helicopter terrain awareness and warning system (HTAWS) is at normal operation or not is determined; if the helicopter terrain awareness and warning system (HTAWS) is at normal operation, a warning inhibition logic operation method is enabled to inhibit false alarm; if the helicopter terrain awareness and warning system (HTAWS) is at abnormal operation, the warning inhibition logic operation method is disabled. The provided method is advantageous in that, by use of the method, terrains or obstacle alarm sources which will not bring actual threat to a flight are eliminated; the method is flexible in coping with multiple flight conditions; interference in normal operations of a flight crew is reduced, and reliability is increased.

Description

technical field [0001] The invention relates to a helicopter forward-looking warning, in particular to a condition-triggered helicopter forward-looking prediction false alarm suppression method. Background technique [0002] With the increasing application of helicopters in all walks of life in my country, the reliability requirements for the Helicopter Terrain Awareness and Warning System (HTAWS) are becoming increasingly urgent. The variable mission types of helicopters, the low flight altitude, and the characteristics of being easily affected by complex meteorological conditions all determine the important role of HTAWS in avoiding controlled flight into terrain (CFIT) of helicopters. At present, in terms of forward-looking prediction, the HTAWS system mainly forms an alarm envelope by inputting real-time flight parameter information, and compares it with the terrain database to determine whether there is a CFIT risk. The above flight reference information only involves ...
