specific Embodiment 1

[0070] An embodiment of the present invention provides an optimization method for reducing false alarms in special areas, including:

[0071] Alarm steps for special areas:

[0072] Set special areas according to terrain data;

[0073] When an aircraft enters a special area, the aircraft is alerted.

specific Embodiment 2

[0074] Such as figure 1 As shown, the embodiment of the present invention provides an optimization method for reducing false alarms in special areas, including:

[0075] Special area alarm step S101:

[0076] According to the terrain data, set the special area and its restricted height [h 1 , h 2 ], limit time [t 1 ,t 2 ]; at the time limit [t 1 ,t 2 ], when the aircraft enters the special area or is about to enter the special area, obtain the altitude data of the aircraft; when the altitude of the aircraft is at the restricted altitude [h 1 , h 2 ], the aircraft is alerted;

[0077] Temporary danger zone setting step S102:

[0078] Set or cancel the temporary danger zone online, which is used to directly warn the aircraft;

[0079] Allowable flight altitude determination step S103:

[0080] When an aircraft enters a special area with height restrictions, it is judged whether the aircraft has a permitted flight altitude; for an aircraft with a permitted flight altit...

Abstract

The present invention provides a method and system for optimization of reducing false alarms of alarms in a special area. The method comprises: a special area alarm step, setting multiple-variable parameters to make an alarm mechanism more flexible; a temporary danger area setting area, changing the alarm parameters from off-line parameters to on-line parameters to allow a system to open and close the temporary danger area in the condition without restarting; an allowable flight height determination step, performing an alarm mechanism based on the allowable flight height for an aircraft with the allowable flight height to reduce the false alarms to the aircraft; an alarm inhibition list setting step, adding a military aircraft to the alarm inhibition list to reduce the false alarms to the military aircraft; and an alarm information partition pushing step, allowing controllers to pointedly only receive the alarm information in the management area where the controllers are located. The method and system for optimization of reducing false alarms of alarms in the special area are able to reduce the conditions of false alarms in the special area, avoid too many false alarms to make controllers numb and reduce the occurrence of accidents.

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 in special areas. Background technique [0002] Special area is a general term for dangerous area, restricted area and restricted area. The danger zone means that there may be dangerous activities to the flight in this airspace within the specified time, and the pilot can decide whether to enter the airspace at his own discretion. A restricted area is an airspace with a higher level of restriction and restriction than a dangerous area, but lower than a restricted area. Flying in this airspace is not an absolute restricted area, and pilots need to obtain approval to enter this area. The processing mechanism of the system in the special area alarm is to set an area in the system according to the coordinates given in the special area, and the aircraft will give an early warning when entering this area,...
