Problems solved by technology

[0003] However, these airborne broadband communication systems all adopt IP technology, and there are problems such as physical layer incompatibility with traditional airborne buses such as ARINC 429 and ARINC 717, and incompatibility of synchronous / asynchronous transmission, so these new airborne broadband communications cannot be directly used system to carry the content transmitted on the traditional airborne bus
[0004] The current solution is to collect these traditional airborne bus data on the aircraft, store them in a non-volatile storage medium, and read them by manual copying after the aircraft lands, but this method has poor real-time performance and poor traceability. Shortcomings

Abstract

The invention discloses a communication method and system for an airborne broadband communication system. The method includes the following steps: A. Simulate the behavior logic of the peer device to maintain continuous communication, and obtain data and physical layer information in the first subnet B, read the physical layer information and extract data, and map the data into the protocol layer, and group the data; C, extract the protocol layer information, select the corresponding communication system to send the data packet; D, receive the data packet, according to The reverse processing of steps A to C is restored to the bus data packet in the first subnet and sent to the second subnet. This method improves the timeliness and traceability of data collection, and can significantly improve the operating efficiency of airlines.
