10M1553B bus controller backup method based on star topology

Abstract

The invention provides a 10M1553B bus controller backup method based on star topology, the backup design method mainly comprises a bus controller, a backup bus controller and a logic concentrator, thebus controller and the logic concentrator are separated independent units, fault isolation can be realized, a processor, a bus monitor and a message mapping table are integrated in the logic concentrator, the running state of a bus is monitored in real time, semaphore signals are used as auxiliary switching signals, the reliability of the system is improved, and a central processing unit issues afinal switching instruction. According to the 10M1553B bus controller backup method provided by the invention, aiming at a topological structure and a communication mechanism of a 10M1553B bus, a bushealth monitoring mechanism is designed by utilizing a logic concentrator, and a double-channel logic concentrator message forwarding mapping table switching mechanism is designed, so that the backupbus controller is flexibly and reliably switched into the bus controller; and meanwhile, the reliability of the system is improved through semaphore auxiliary switching.

Description

technical field [0001] The invention relates to the field of communication technology of airborne avionics equipment and storage management equipment, in particular to a backup method for a 10M1553B bus controller based on a star topology. Background technique [0002] The bus controller of the 10M1553B bus system undertakes important functions such as 10M1553B bus data communication control, management, maintenance, and Internet access management. When the controller fails or the function of the bus controller is migrated, the backup bus controller takes over functions such as bus control and management. Therefore, we propose a 10M1553B bus bus controller backup method based on star topology. Contents of the invention [0003] The purpose of the present invention is to provide a 10M1553B bus controller backup method based on star topology, to solve the problem of the 10M1553B bus system bus controller failure or bus controller function migration proposed by the above-men...
