technical field

Background technique

As a data communication network for aerospace systems, its speed is 1Mbps; with the advancement of technology, in the network The amount of transmitted data has increased dramatically, and the network transmission rate of 1Mbps based on the MIL-STD-1553B protocol can no longer meet its communication requirements. Therefore, a fiber-optic FC-AE-1553 protocol network is proposed to replace the twisted pair-based MIL-STD-1553B network. . Among them, FC-AE-1553, as a sub-protocol of FC-AE, defines the upper-layer protocol mapping of FC-AE to MIL-STD-1553. One of its purposes is to allow the use of installed MIL-STD-1553 equipment software and hardware, through The familiar MIL-STD-1553 concept is used to establish the mapping, so that the network can be upgraded smoothly, and the compatibility of the network is also improved.

In the prior art, a bridge is used to enable the original MIL-STD-1553B equipment to be seamlessly integrated into the FC-AE-1553 network. However, the existing technology can only solve the problem of protocol conversion between MIL-STD-1553B and FC-AE-1553, and topology still occurs when various devices (such as GJB1188B electrical connectors, external serial devices) perform data conversion. Complex and practical scene wiring is difficult, messy and complicated.

Therefore, how to provide a multifunctional bus bridge as a high-speed transmission channel between diversified device interfaces, simplify complex topology in a communication system, and improve communication efficiency and quality, has become an urgent problem to be solved.
