Embodiment Construction

[0020] The present invention analyzes air traffic control navigation information data, air traffic control operating environment data (airspace data), flight dynamic data and flight monitoring data characteristics, and designs a metadata representation model, with the purpose of realizing metadata modeling and data structure of typical air traffic control data It includes airspace data, flight telegraph data, aeronautical information data, air traffic control radar data and ACARS data. Aiming at the structured air traffic control data and the dynamic air traffic control data flow, the registration warehouse model of air traffic control information is designed to realize the processing and exchange of multi-system data.

[0021] The present invention designs an XML style sheet to format the air traffic control data stored in the XML document, with the purpose of enabling a large number of non-uniform air traffic control data to be displayed in a unified standard. Design a data ...

Abstract

The invention relates to the technical field of information processing and provides an air traffic control information sharing system based on extensive makeup language (XML). Aiming at achieving metadata modeling and data structuring presentation of typical air traffic control data and achieving processing and exchange of system data, the system includes adopting the schema in the XML to standardize the air traffic control information. The system further includes a data sharing step. The data sharing step specifically includes first utilizing the Dietz coding rule to describe an XML document into a tree structure, namely the visiting sequence of elements is the serial number of preorder traversal of the elements if sequential access is conducted on the XML document in text form, otherwise texts of the XML document can be reconstructed in the schema of a document tree in preorder traversal. Corresponding queue nodes can be generated by Dietz coding and Java document object model (JDOM) analyzing and are read into a corresponding attribute list according to a queue node relation schema, and XML query is navigated by utilizing a route expression. The system is mainly applied to information processing.

Description

technical field [0001] The invention relates to the fields of information technology and database design. Specifically, it involves the air traffic control information sharing system based on XML. Background technique [0002] With the development of the aviation industry, it is becoming more and more important to break the regional system information islands and change the mode of each regional air traffic control department's independent processing of flight plan data for breakthroughs in air traffic efficiency and safety. Aviation information sharing is the core of realizing the operation mode of regional air traffic control automation system. At present, air traffic control departments in domestic regions use air traffic control automation systems from different manufacturers, with a large amount of information and a complex and inconsistent structure. XML follows strict syntax requirements, and has the characteristics of scalability and flexibility, suitable for struc...
