Ground terminal system capable of sending different types of data link messages and operation interface

Abstract

The invention discloses a ground terminal system capable of sending different types of data link messages and an operation interface. The ground terminal system comprises an input terminal, a marshalling module and a sending routing terminal, the input terminal receives the message body, the message type identifier and the sending command; the marshalling module identifies a message type and a target receiving end according to the message type identifier, and marshals the message types according to a predetermined format to form a routing table, and informs the protocol stack of a target receiving end corresponding to the current message according to a routing rule in the routing table; the sending routing terminal sends the message to a corresponding target receiving end through the protocol stack according to the routing rule in the routing table. According to the invention, the message sending routing terminal which can send all data link applications based on the aircraft communication address and the report system network on the same terminal interface sends the message body to the corresponding target receiving end according to the protocol stack and the sending path matched with the message type, the structure is simple, and the operation is convenient.

Description

Technical field[0001]The present invention relates to the field of data link communication, and more particularly to a terrestrial terminal system and an operation interface that can transmit different types of data chain messages.Background technique[0002]At present, my country's civil aviation passenger plane is in full swing, and the data chain communication system is an indispensable function, and the ODM, OEM manufacturers and many research institutions are developing and producing airborne data. During the link system, connection testing is an indispensable ring. However, the current status of the current ground data chain application terminal is:[0003](1) The open space data chain network is extremely large, including a series of ground stations, communication subnets, and air traffic control center and airline operation management center software, in the present invention, mentioned that the ground terminal refers to the empty tube center application terminal software system...

AI Technical Summary

Problems solved by technology

The real air-ground data link network has extremely high security requirements. Allowing the experimental data to enter the network of the airport air traffic control center and the airline operation control center may bring security risks. Therefore, under normal circumstances, the application and It is impossible for the equipment to access the data link operation network;

[0004](2) The application terminal software system of the air traffic control center and the application terminal software system of the airline operation management center are a combination of extremely large applications, including data link applications. Many messages in each data link application terminal will have a separate operation interface and complex operation process, therefore, they are very complex software systems, and are not suitable for quick and easy support of airborne application research, development, production and other stages Debugging and quick testing

At present, there are few analog ground application terminals, and most of them are developed independently according to the type of application, such as ATS ground application terminals, AOC ground application terminals, FANS ground application terminals, etc., which are not comprehensive and concise. The system is huge and complicated, and there are many limitations in laboratory use
