Onboard seamless data transmission wireless communication system and method

Abstract

The invention discloses an onboard seamless data transmission wireless communication system and method. The onboard seamless data transmission wireless communication system comprises an onboard system and a ground system. The onboard system comprises a data merging router, a built-in subnet and an onboard communication system, wherein the built-in subnet is in signal connection with the data merging router. The ground system comprises a data center, a ground communication system and a ground supporting system, wherein the ground communication system is in signal connection with the data center, and the ground communication system is in signal connection with the onboard communication system. The data merging router is used for merging a plurality of single communication links into a unified external communication transmission channel and building the external communication transmission channel communicated with the data center. The data merging router is provided with a communication control interface module. The communication control interface module is used for controlling the onboard communication system to externally initiate a single communication link connecting request to build a communication transmission channel. The onboard seamless data transmission wireless communication system is convenient and flexible to use, smooth in data transmission, short in data switching delay and high in transmission reliability.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an airborne seamless data transmission wireless communication system and a communication method thereof. Background technique [0002] With the development of communication technology, the application of airborne communication is increasing day by day. In the existing civil aviation passenger aircraft, in addition to the traditional communication and navigation system for real-time communication with the ground, the real-time communication and data between the airborne system (such as avionics system, cabin system, entertainment system, information system, etc.) and the ground network The transmission service has also given birth to the development and application of various in-flight and off-board communication means; for example, when the aircraft stays at the airport, it can use cellular mobile communication (3G, 4G, etc.) or WLAN to communicate with The ground network p...

AI Technical Summary

Problems solved by technology

[0004] (1) The external communication channel of a certain system is fixed and cannot be used interchangeably. It is not flexible enough in use and operation, and cannot be used for disaster recovery backup; for example, the data transmission between the airborne maintenance system and the ground can only be transmitted through satellites channel, while the in-flight entertainment system can only update the program content of the server through cellular communication or WLAN when the aircraft is parked at the airport

[0005] (2) The external communication channels of each system on the aircraft are independent. In this case, the bandwidth of these channels cannot be fully utilized, and there is a waste of resources

[0006] (3) For some systems with more than one communication channel, when the business application is using one communication method for data transmission, if the current transmission link is unavailable, the service will be interrupted, and the transmission link will be interrupted. After the road is restored or switched to another transmission link, it needs to be restarted, and the data switching delay is relatively large
