Embodiment Construction

[0020] The automatic generation algorithm of RVSM area is proposed on the basis of fully studying the buffer generation algorithm in GIS. RVSM region generation process see figure 1 .

[0021] 1. Basic concepts

[0022] For the convenience of the proposed automatic generation algorithm, the following concepts and definitions are first given.

[0023] A buffer zone refers to a band of certain width established around a geographic entity or spatial object in order to identify its proximity or influence on its surroundings.

[0024] Definition 1: The curve formed by ordered coordinate points is called the axis.

[0025] Definition 2: The intersection of two adjacent line segments on the axis is called the inflection point.

[0026] Definition 3: Along the direction of the axis, the buffers generated on the left and right are called the left and right buffers of the axis, respectively.

[0027] Definition 4: Three points in sequence on the axis, using the right-handed spiral ...

Abstract

The invention relates to a graphic fusion based method for automatically generating an air traffic control airway route RVSM region. The method comprises the following steps: reading checkpoint information on an airway in turn, saving the points on the airway into an array in turn, and obtaining the RVSM region of the airway through the 'linear rotation generation method' of the points in the array and the 'point rotation generation algorithm' of the points at both ends; and fusing the RVSM regions of all the airways in a specific air space to form the RVSM region of the air space, and finallydisplaying the RVSM region on the display. The method is used for automatically generating the airway route RVSM region according to the airway route situation in a database, thereby facilitating theimplementation of adding flight height levels and air space capacity, reducing the work load of air traffic control and command, facilitating the dispatching of flight collisions by the controllers,and improving flight safety and reducing the work load of air traffic control and command.

Description

technical field [0001] The technical proposal belongs to the field of GIS and computer technology. Involves graphics fusion and buffer algorithms. Background technique [0002] With the rapid development of my country's aviation industry and the rapid increase of aircraft, more stringent requirements are put forward for the air traffic control automation system. The minimum vertical separation (RVSM Reduced Vertical Separation Minimum) refers to the reduction of the vertical separation standard between 8400 meters and 12500 meters (including these two levels) from 600 meters to 300 meters in the airspace where RVSM operations are implemented. Flight activities conducted in accordance with such standards are called minimum vertical separation flights. After adding the RVSM area, if the RVSM area is managed by the conventional method, the controller will repeatedly draw the complex RVSM area. Contents of the invention [0003] The object of the present invention is to pro...
