Embedded Mil - Std - 1553 - B Aviation Communication Bus Terminal Interface Design Agreement

MIL-STD-1553B data bus is an information transmission bus standard foraircraft equipment which is developed by the U.S. military. With the development ofcomputer technology, the integrated aerospace electronics system has beencontinuously developed. It is usually not a separate system. It consists of severalsub-systems which interconnect through the embedded bus interface and the busmedium. The resources of each subsystem are shared by network. Such an integratedsystem effectively reduces the size and weight of the overall system, saves the space,avoids confusion and improves the comprehensive performance of the system.Therefore, the design of MIL-STD-1553B bus terminal interface is a key componentfor achieving the aerospace electronics system integration. It mainly completes theinformation integration, resources sharing, task coordination, fault tolerant andreconstruction.Many domestic aerospace sectors have begun to use the1553B bus for datatransfer and many late-model products also intend to use this data bus. With thestrengthening of integration requirements, the importance of the communicationsystems continues to improve. As the current preferred standard in the aerospacefields,1553B gets more and more attentions. And its key role is increasinglyprominent. In the next few years, it will be still the mainstream of national aerospacebus technology.I did an in-depth study of military MIL-STD-1553B data bus protocol and usedthe U.S. DDC’s BU-61580protocol chip as the core to design and develop thecommon interface of embedded1553B terminals. I described the connection methodbetween the microcontroller and the protocol chip and software implementations. Theterminal can be programmed to achieve three kinds of terminal mode of1553B: BC,RT, MT.
