Design and Realization of Redundancy Management Method in Variable Structure Bus Controller

With the digital development of aviation and aerospace,1553B bus is widely used in control system.For the demands of reliability and safety for the launch and control system,aiming at a self-determination variable structure bus controller,an embedded redundancy management method is designed and realized based on synchronization,data across chain communication and reconstruction technology.The bus system is reconfigured independently when a recoverable failure happened.Finally,experimental results show that the software method is reliable and stable,which can meet the needs of engineering application,and has broad application prospects.
