Problems solved by technology

Flight program design and airport management personnel usually use manual drawing method for analysis and calculation, and build a sand table model to display. Due to the complicated calculation and large measurement error, it is easy to make mistakes, and consumes a lot of manpower and material resources.
In addition, before the construction of the airport, when communicating with local governments and non-professionals, the two-dimensional presentation method seriously restricted their understanding of navigation standards, adding unnecessary obstacles to the construction of the airport and the erection of navigation facilities

Embodiment 1

[0020] Embodiment 1 - three-dimensional presentation of chart elements:

[0021] First establish the basic information of the airport, input the code of the airport, the geographical coordinates of the airport, magnetic difference, elevation, the length and width of the runway, the magnetic direction, the type of navigation station / location point, geographical coordinates, the type of the route, Height, approach and departure runways, node information, geographic coordinates of obstacles, height information, and airspace type, upper limit height and other information, these information are converted into stored information in the database through calculation and stored in the multi-airport database, and are also recorded in the chart The 6 functional modules in the element data management module classify and manage these data.

[0022] According to the needs of customers, the three-dimensional generation function module of air chart elements calls out one or more air chart ele...

Embodiment 2 3

[0024] Embodiment 2 - Three-dimensional route real-time multi-angle roaming:

[0025] First establish the basic information of the airport with embodiment one, mainly guarantee the type of route, height, approach and departure runway, node information, the type of navigation station / locating point, the accuracy of geographic coordinates.

[0026] According to the needs of customers, the route is selected, and the three-dimensional route roaming module uses the information to automatically generate a three-dimensional route roaming algorithm, connects the nodes of the route, and at the same time simulates the roaming effect in three dimensions on the Google Earth technology platform. Realize the route roaming experience designed by controllers and pilots for specific flight procedures, verify the rationality of airport flight procedure design, and observe terrain and assess obstacles during route roaming. The system realizes the real-time simulation of 3D roaming along the spec...

Embodiment 3

[0027] Embodiment three - real-time three-dimensional dynamic simulation of multi-airline traffic flow:

[0028] First, the basic information of the airport is established with the first embodiment, mainly to ensure the type of route, altitude, approach and departure runway, node information, the type of navigation station / location point, and the accuracy of geographic coordinates.

[0029]According to customer needs, select any flight plan, and the traffic flow simulation module will call out corresponding flight data of multiple flights from the database, calculate the location data of the flight flight through the traffic flow simulation algorithm, and send it to the KML result data platform , generate relevant kml files, dynamically load the generated kml files on Google Earth (GoogleEarth) technology platform, and realize multi-airline traffic flow three-dimensional dynamic simulation through the three-dimensional dynamic rendering module.

[0030] The basic requirement o...

Abstract

The invention discloses a three-dimensional analog simulation system of an instrument flight program. The system comprises a multi-airport database, a chart element data management module, a chart element three-dimensional generation functional module, a three-dimensional flight course roaming module, a traffic flow analogue module, a navigation station shielding evaluation module, a keyhole markup language (KML) result data platform, a goggle geotechnical platform, a three-dimensional dynamic representation module and a geographic information system technical platform. The simulation system provides three-dimensional visualization technology for representing vision and instrument flight program design, so that 3D dynamic demonstration is formed by navigation elements designed by a two-dimensional diagram, works such as planning, demonstration, reporting and the like of related works such as airspace planning, vision, instrument flight program design, airport construction, navigation facility planning, site selection and the like are vivid and intuitive, the cost and the time cost of site exploitation, planning, airspace coordination, navigation facility shielding evaluation, airport clearance protection and evaluation and the like are reduced, and further the safety guard capacity of related works of civil aviation is improved.

Description

technical field [0001] The invention relates to a three-dimensional simulation system for an instrument flight program, which is used for visually displaying the design results of the airport flight program in a 3D display environment and evaluating its rationality, and belongs to the technical field of computer applications. Background technique [0002] With the rapid development of my country's civil aviation industry, the number of aircraft continues to increase, the scale of airport construction is getting larger and larger, and the construction speed of new airports is also accelerating. , is still at the stage of "on-the-spot measurement and drawing on paper". Even if the electronic map is used to represent the airport, navigation station, and obstacles, it is limited to two-dimensional presentation. The method is not intuitive, but also requires a lot of work. Flight program design and airport management personnel usually use manual drawing method for analysis and cal...
