Description

Technical Field

[0001] This invention relates to the field of safety assessment of proposed buildings in airport aircraft radar guidance zones, and more particularly to a method and system for safety assessment of proposed buildings based on aircraft radar guidance zones. Background Technology

[0002] Airport airspace safety is a core prerequisite for ensuring the safety of aircraft takeoff, landing, and low-altitude flight. The radar guidance area, as a critical area for airport navigation and control, directly determines the compliance requirements of proposed buildings within its height restrictions and coverage. With rapid urbanization, the number of proposed buildings around airports is increasing annually. If the height of these buildings exceeds the radar guidance area and airspace reference height limits, it can interfere with radar navigation signals, affect aircraft flight attitude, and even cause flight safety accidents.

[0003] Currently, in airport airspace management, the safety assessment of proposed buildings mainly relies on manual judgment combined with basic data. There is a lack of systematic and precise technical methods, making it difficult to quickly and accurately match the radar guidance zone coverage and airspace height requirements, which poses a hidden danger to airport airspace safety. In the existing technology, the safety assessment of proposed buildings mainly includes the following two methods: (1) Manual assessment method: Manually judge whether the building is too tall or within the radar guidance zone control range. This method relies on the professional ability of the staff, is inefficient, and is prone to errors in manual calculation and judgment, making it difficult to guarantee the accuracy of the assessment. (2) Simple data overlay method: Simply overlay the radar guidance zone boundary data with the building data, without accurately assigning values ​​and projecting the airspace reference height. It is impossible to achieve accurate comparison between the radar guidance zone sector height and the building height. Moreover, the data format is not uniform, making it difficult to integrate into the GIS system for visualization and efficient analysis. The scope of application is limited, and it cannot meet the needs of large-scale and precise assessment. In summary, the existing technology has the disadvantages of low assessment efficiency, poor accuracy, non-standard process, and weak data integration ability, and cannot efficiently adapt to the precise assessment needs of proposed buildings in airport airspace management. Summary of the Invention

[0004] The purpose of this invention is to provide a method for safety assessment of proposed buildings based on aircraft radar guidance zones. This method extracts radar guidance zones containing several radar sectors from flight radar guidance zone data, constructs a GIS tool system to realize the unified benchmark latitude and longitude expression and accurate matching of obstacle control parameters in the radar guidance zone and proposed building data according to WGS84 latitude and longitude projection, and uses the automated assessment logic rules of this invention to perform standardized, automated, efficient, and rapid assessment of proposed buildings. This method can quickly and accurately identify proposed buildings that exceed limits and affect radar guidance safety, and issue excessive warnings.

[0005] The objective of this invention is achieved through the following technical solution: A method for safety assessment of proposed buildings based on aircraft radar guidance zones, the method comprising: S1. Obtain the airport's basic geographic data and flight radar guidance area data, including the airport under study, from the ARINC424 navigation database; S2. Construct a GIS tool system, express the airport's geographical basic data into the GIS tool system according to latitude and longitude information, extract the radar guidance area from the flight radar guidance area data and express it into the GIS tool system. The radar guidance area contains several radar sectors, and each radar sector is set with obstacle control parameters, including height limit parameters. S3. Collect the data of the proposed building and express it into the GIS tool system according to the latitude and longitude information. The building data includes the name of the proposed building, latitude and longitude, and design height. If the latitude and longitude of the proposed building is within the radar sector of the radar guidance area, the design height of the proposed building is compared and evaluated with the height limit parameter corresponding to the radar sector. Proposed buildings whose design height is greater than the height limit parameter of the radar sector are evaluated as not meeting the airspace safety requirements and the overheight data is calculated. The overheight data is the difference between the design height of the proposed building and the height limit parameter of the radar sector.

[0006] To better implement the present invention, in method S3, if the latitude and longitude of the proposed building are not within the radar guidance zone, the proposed building is determined to meet the airspace safety requirements; in the comparative evaluation of the latitude and longitude of the proposed building within the radar sector of the radar guidance zone, if the design height of the proposed building is less than or equal to the height limit parameter of the radar sector, the proposed building is evaluated as meeting the airspace safety requirements.

[0007] Preferably, in method S2, obstacle control parameters are set according to latitude and longitude within the radar sector; in method S3, the design height of the proposed building is compared and evaluated with the height limit parameters corresponding to the radar sector according to latitude and longitude.

According to method S3, obstacles in the airport obstacle data that do not meet the airspace safety requirements are screened and output.

[0009] Preferably, the latitude and longitude coordinates of the GIS tool system adopt WGS84 latitude and longitude coordinates; in method S3, the planning plan CAD drawings of the proposed building data are collected, the planning plan CAD drawings are imported into Globalmapper software, the planning plan location of the building is converted into WGS84 latitude and longitude coordinates using Globalmapper software, and then the proposed building is expressed in the GIS tool system according to the latitude and longitude information.

[0010] Preferably, in method S3, an assessment report is generated after an airspace safety assessment is performed on the proposed building data. The assessment report includes a subset of building data that meets airspace safety requirements and a subset of building data that does not meet airspace safety requirements. The subset of building data that does not meet airspace safety requirements is stored in association with the proposed building name, latitude and longitude, and superelevation data.

[0011] Preferably, the proposed buildings that do not meet the airspace safety requirements are visualized in the map of the GIS tool system. The proposed buildings that do not meet the airspace safety requirements are indicated by warning colors. Color warnings are displayed at the map locations of the proposed buildings that do not meet the airspace safety requirements, and the excessive height data is shown.

[0012] Preferably, in method S2, the obstacle control parameters are sourced from obstacle control data in flight radar guidance area data and / or airspace reference altitude map data from airport airspace management authorities.

[0013] Preferably, in method S1, the flight radar guidance area data also includes data on the area outside the study airport obtained from the ARINC424 navigation database.

[0014] A building construction safety assessment system based on aircraft radar guidance areas includes an ARINC424 navigation database, a data acquisition module, a GIS tool system, a database of proposed buildings, and a comparative assessment module. The data acquisition module obtains airport geographic baseline data and flight radar guidance area data including the airport from the ARINC424 navigation database. The data acquisition module then expresses the acquired airport geographic baseline data in the GIS tool system according to latitude and longitude information.

Each radar guidance area contains several radar sectors, and each radar sector corresponds to an obstacle control point. The obstacle control parameters include height restriction parameters; the proposed building database stores proposed building data, which includes the proposed building name, latitude and longitude, and design height; the GIS tool system is also used to express the proposed building data according to latitude and longitude information; the comparison and evaluation module filters proposed buildings whose latitude and longitude are within the radar sector of the radar guidance area for evaluation; the comparison and evaluation module further filters proposed buildings whose design height is greater than the height restriction parameter of the radar sector and evaluates them as not meeting the airspace safety requirements and calculates the overheight data, which is the difference between the design height of the proposed building and the height restriction parameter of the radar sector.

[0018] The present invention will be further described in detail below with reference to embodiments: Example like Figure 1 As shown, the proposed building safety assessment method based on the aircraft radar guidance zone includes the following methods: S1. Obtain the airport's geographical baseline data and flight radar guidance area data (including radar guidance area coverage, radar sector, sector height, obstacle control parameters, etc.) from the ARINC424 navigation database. Preferably, the flight radar guidance area data also includes data on areas outside the research airport obtained from the ARINC424 navigation database; that is, in addition to including the research airport, the flight radar guidance area data can also include flight radar guidance area data for areas outside the research airport (i.e., extending the application to areas outside the research airport). A visualization of the flight radar guidance area data including the research airport and areas outside the research airport in the GIS tool system is shown below. Figure 2 As shown.

[0019] S2. Construct a GIS tool system. This system is used to visualize, match latitude and longitude coordinates, and perform spatial analysis of various spatial data. Preferably, the latitude and longitude coordinates of the GIS tool system use WGS84 coordinates. Airport geographic basic data is expressed in the GIS tool system according to latitude and longitude information. Radar guidance areas are extracted from flight radar guidance area data and expressed in the GIS tool system. Each radar guidance area contains several radar sectors (e.g., three radar sectors with average height limits of 80 meters, 100 meters, and 120 meters respectively). Each radar sector has corresponding obstacle control parameters, which are set according to latitude and longitude within the radar sector. Preferably, the obstacle control parameters are sourced from obstacle control data in the flight radar guidance area data and / or the airspace reference height map data from the airport airspace management department (the airspace reference height map data also provides a standard basis for height determination). The obstacle control parameters include height limit parameters. This embodiment uses obstacle control parameters sourced from obstacle control data in flight radar guidance area data and airspace reference altitude map data from airport airspace management departments; wherein, when using airspace reference altitude map data, such as Figure 4 As shown, polylines are drawn using CAD software to close the various height control areas in the clearance reference height map, forming closed area graphics. The closed graphics are then imported into Globalmapper software, and precise height values ​​are assigned to each closed area (i.e., each sector) according to the clearance reference height requirements. After the height assignment is completed, the data in Globalmapper is converted from UTM projection format to WGS84 latitude and longitude projection and exported as Geojson data format, which facilitates subsequent data fusion with obstacle control data in the flight radar guidance area data in the GIS tool system.

[0020] S3. Collect the proposed building data and express it in the GIS tool system according to latitude and longitude information. The building data includes the proposed building name, latitude and longitude, and design height. In some embodiments, collect the planning plan CAD drawings of the proposed building data, import the planning plan CAD drawings into Globalmapper software, use Globalmapper software to convert the planned plan location of the building into WGS84 latitude and longitude coordinates, and then express the proposed building in the GIS tool system according to latitude and longitude information. Organize the proposed building data, convert the building's plan location into latitude and longitude coordinate format, and integrate it with the building's design height data to form a standardized building data list. Import it into the GIS tool system for evaluation and processing to ensure that the data can be accurately matched with radar guidance area data and clearance reference height data. Integrate the processed radar guidance area data and clearance reference height data into the GIS tool system to form a unified visual evaluation interface; accurately compare the imported proposed building data (latitude, longitude, and height) with the radar guidance area coverage and clearance reference height of each sector in the GIS tool system.

[0021] like Figure 3 As shown, in a GIS tool system, if the latitude and longitude of a proposed building are not within the radar guidance area, the proposed building is deemed to meet airspace safety requirements. Figure 3 As shown, if the latitude and longitude of the proposed building are within the radar sector of the radar guidance area, the design height of the proposed building is compared and evaluated with the height restriction parameter corresponding to the radar sector. Proposed buildings whose design height is greater than the height restriction parameter of the radar sector (i.e., the design height of the proposed building > the height restriction parameter of the corresponding radar sector) are assessed as not meeting airspace safety requirements, and the overheight data is calculated. The overheight data is the difference between the design height of the proposed building and the height restriction parameter of the radar sector. In the comparative evaluation of the proposed building's latitude and longitude within the radar sector of the radar guidance area, such as... Figure 3 As shown, if the design height of the proposed building is less than or equal to the height limit parameter of the radar sector (i.e., the design height of the proposed building ≤ the height limit parameter of the corresponding radar sector), the proposed building is assessed as meeting the airspace safety requirements. In some embodiments, each radar sector of the radar guidance area is provided with obstacle control parameters. The obstacle control parameters are set according to latitude and longitude within the radar sector. The data of the proposed building and the obstacle control parameters of each radar sector in the radar guidance area are expressed in the GIS tool system according to latitude and longitude information and spatially aligned and matched. The design height of the proposed building is compared and evaluated with the height limit parameter corresponding to the radar sector according to latitude and longitude.

[0022] In some embodiments, after performing a clearance safety assessment on the data of the proposed building, an assessment report is generated. The assessment report includes a subset of building data that meets the clearance safety and a subset of building data that does not meet the clearance safety. The subset of building data that does not meet the clearance safety is stored in an associated manner according to the name of the proposed building, longitude and latitude, and over-height data. Through the front-end display interface of the GIS tool system, the assessment results of the proposed building are output, including: building location (longitude and latitude), whether it is within the radar guidance area, the clearance reference height of the corresponding sector, the designed height of the building, assessment conclusion (qualified / unqualified), reasons for non-conformance (over-height value, controlled area where it is located), forming a standardized assessment report for easy access, review, and archiving by the airport clearance management department. In some embodiments, the proposed buildings that do not meet the clearance safety are visually expressed on the map of the GIS tool system. The proposed buildings that do not meet the clearance safety are expressed in a warning color, and color warnings are used at the map locations of the proposed buildings that do not meet the clearance safety and the over-height data is displayed. The airport data and flight radar guidance area data in the ARINC424 navigation database are combined with GIS data. Using longitude and latitude, the coverage range, zoning, and sector height of the radar guidance area are displayed using the GIS tool system; at the same time, the reference height map provided by the airport is imported into Globalmapper after closing the area with polylines. Heights are assigned to each sector in Globalmapper, and finally, the UTM projection is converted into longitude and latitude for export in the Geojson format, and then integrated into the GIS tool system for front-end display through the GIS tool system; the building data is sorted into the longitude and latitude format and imported into the system. At the same time, based on the building height, the radar guidance area height, and the reference height map, it is determined whether the proposed building is over-height. The following is an example of this embodiment: The data of 10 proposed buildings are sorted. The planned plane positions of each building are converted into WGS84 longitude and latitude coordinates and associated with the corresponding designed heights (ranging from 50 meters to 130 meters) to form a building data list in Excel format and imported into the GIS tool system to match the longitude and latitude of each building with the coverage range of the radar guidance area and the sector height for comparison and judgment: Among them, 6 buildings are not within the radar guidance area and are judged qualified; 3 buildings are within the radar guidance area and the designed height ≤ the clearance reference height of the corresponding sector and are judged qualified; 1 building is within the 120-meter sector range, with a designed height of 130 meters, exceeding the clearance reference height by 10 meters, and is judged unqualified, giving an over-height warning. Then, through the front-end interface of the GIS tool system, an assessment report including the detailed information and assessment conclusions of 10 buildings is generated, marking the specific locations, over-height values, and sectors where the unqualified buildings are located, exported in PDF format, and submitted to the airport clearance management department.

[0023] This invention can also extract airport obstacle data from the ARINC424 navigation database and express it in a GIS tool system. The airport obstacle data includes obstacle number, obstacle latitude and longitude, and obstacle elevation data. According to the method of this invention, obstacles in the airport obstacle data that do not meet the airspace safety requirements are screened and output.

[0024] A proposed building safety assessment system based on aircraft radar guidance areas includes an ARINC424 navigation database, a data acquisition module, a GIS tool system, a proposed building database, and a comparative evaluation module. The data acquisition module retrieves airport geographic baseline data and flight radar guidance area data (including the airport) from the ARINC424 navigation database. The data acquisition module then expresses the acquired airport geographic baseline data in the GIS tool system according to latitude and longitude information. The data acquisition module also extracts radar guidance areas from the flight radar guidance area data and expresses them in the GIS tool system. Each radar guidance area contains several radar sectors, and each radar sector corresponds to obstacle control parameters, including height restriction parameters. The proposed building database stores proposed building data, including the proposed building name, latitude and longitude, and design height. The GIS tool system is also used to express the data of proposed buildings according to latitude and longitude information. The comparison and evaluation module filters proposed buildings whose latitude and longitude are within the radar sector of the radar guidance area for evaluation. The comparison and evaluation module further filters proposed buildings whose design height is greater than the height limit parameter of the radar sector and evaluates them as not meeting the airspace safety requirements and calculates the overheight data. The overheight data is the difference between the design height of the proposed building and the height limit parameter of the radar sector.

[0025] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
