specific Embodiment 1

[0059] Such as figure 1 As shown, the embodiment of the present invention shows an optimization method for reducing the minimum safety altitude warning false alarm, including:

[0060] Minimum safe altitude warning step S101:

[0061] According to the terrain data of the warning area and the height data of obstacles, the warning area is divided into multiple partitions, and the minimum safe altitude is set for each partition respectively; An alarm is issued when the minimum safe height of the partition is reached.

[0062] On this basis, further, it also includes the alarm suppression list setting step S102 and the runway partition intelligent alarm step S103, wherein:

[0063] Alarm suppression list setting step S102:

[0064] Set the alarm suppression list; when the aircraft in the alarm suppression list enters the warning area, the system will not give an alarm to the aircraft; obtain the secondary code of the military aircraft, and add the aircraft with the secondary co...

specific Embodiment 2

[0082] Such as figure 2 As shown, the embodiment of the present invention provides a kind of optimization system that reduces the warning false alarm of the minimum safety height, including:

[0083] Minimum safe altitude warning module 201, which is used to divide the warning area into a plurality of partitions according to the terrain data and the height data of obstacles in the warning area, and set the minimum safe altitude for each partition respectively; when the aircraft enters a certain partition, obtain The altitude data of the aircraft, when the altitude of the aircraft is lower than the minimum safe altitude of the sector, an alarm will be issued;

[0084] On this basis, further, it can also include an alarm suppression list setting module and a runway partition intelligent alarm module, wherein:

[0085] Alarm suppression list setting module 202, which is used to set the alarm suppression list; when the aircraft in the alarm suppression list enters the warning ar...

Abstract

The present invention provides an optimization method and system for reducing false alarm of a minimum safety altitude warning. The method includes the steps of: dividing a region around a runway into runway partitions, wherein a distance threshold is set in the region; and adopting an intelligent calculating method based on landing channels to warn aircrafts. The intelligent calculating method based on the landing channels specifically includes the steps of: judging takeoff / landing states of the aircrafts according to position data and flight situations of the aircrafts; forming a cuboid protection region for the aircrafts in the landing state according to aircraft landing points and initial coordinates when the aircrafts enter the runway; and judging whether the aircrafts are in the cuboid protection region or not according to real-time coordinates of the aircrafts, and giving alarm to the aircrafts when the aircrafts exceed the cuboid protection region. The optimization method and system for reducing the false alarm of the minimum safety altitude warning can accurately perform intelligent alarm according to the takeoff / landing states of the aircrafts in the runway partitions, provide proper alarm prompts, and greatly reduce the false alarm condition which is easily produced in the prior art.

Description

technical field [0001] The invention relates to the technical field of aviation control, in particular to an optimization method and system for effectively reducing false alarms at minimum safety altitudes. Background technique [0002] The minimum safe altitude warning is one of the most important warnings in the air traffic control automation system, and its function is clearly required in the civil aviation industry standards. It is required in this standard that when the effective altitude of the track is lower than or will be lower than the set parameter value within the set alarm time, the system will generate an alarm. [0003] According to the alarm standards and setting parameters, many false alarms will be generated in actual operation. False alarms can easily cause numbness to the controller. Even if there is a real alarm, the controller may think it is a false alarm, resulting in serious safety accidents. Therefore, false alarms need to be minimized. Contents ...
