Abstract

The invention discloses an MIL-STD-1553B bus termination and a redundancy backup method thereof. The MIL-STD-1553B bus termination comprises a wire communication module, a transmission layer implementation module and a wireless communication module. The redundancy backup method is to use wireless communication for completing the task of message transmission when wire communication malfunctions. In the invention, when the failure of cables, couplers, or the termination causes the partial or total failure of the wire communication, the bus termination still guarantees sustaining data transmission capability, thus further enhancing the reliability of Internet. The wire communication module conforms to the existing 1553B bus norm and the wireless redundancy backup method is completely in linewith the upper-layer protocol used by the existing 1553B bus equipment. The bus termination can coexist with other equipment conforming with the 1553B norm in the same 1553B bus network.

Description

technical field

[0001] The invention relates to a MIL-STD-1553B bus terminal and a redundant backup method thereof, belonging to the field of avionics networks. Background technique

[0002] The time-division command / response multiplex data bus (US military standard MIL-STD-1553B, 1553B for short) is a bus standard that satisfies high real-time and high reliability information transmission. It originated in the 1970s, and was first positioned for internal applications in aircraft, and was later extended to other platforms such as ships, tanks, and satellites. After decades of development, its technology has been quite mature and widely used. Almost all military aircraft after the 1970s use this bus to connect airborne electronic devices. Even in aircraft such as F-22 and F-35, which currently advocate integrated avionics, the 1553B bus is still used in the interconnection of subsystems such as aircraft management and external storage management. The GJB-289A standard prom...
