FC bus multi-node simulation method

Abstract

The invention discloses an FC bus multi-node simulation method, proposes a combination scheme of an optical switch assembly, an external optical switch and an FC simulation board card, and achieves the switching of an optical fiber physical link between physical equipment and simulation equipment through the optical switch assembly. By means of the external optical switch, the link UP states of multiple devices can be achieved at the same time, application messages of the multiple devices are sent in a time division multiple access mode through one FC bus data simulation card or simulation channel, and the external optical switch distributes and uploads the application messages to the airborne optical switch according to a channel configured in advance. When the data is received, the external optical switch transmits the data connected with each port of the airborne optical switch to the simulation channel according to the corresponding configuration, so that the purpose of simultaneously simulating the data of a plurality of equipment nodes by using one FC bus data simulation card is achieved; FC simulation board card resources are saved, and expenditures are saved.

Description

technical field [0001] The invention relates to the field of data bus testing, in particular to an FC bus multi-node simulation method. Background technique [0002] For fixed-wing aircraft, helicopters and unmanned aerial vehicles, with the development of airborne data buses, the FC (Fibre Channel) bus with optical fiber as the transmission medium is naturally immune to electromagnetic interference due to its high bandwidth, light cable weight, and natural immunity to electromagnetic interference. The main advantage and becoming a mainstream data bus. The topology of the FC bus includes switching network, arbitrated loop and point-to-point. Because the topology of the switching network can carry a large number of nodes and has the characteristics of strong system scalability, the topology of the current airborne FC bus network is mostly a switching network. An onboard FC switch is required to contact and realize data distribution, and each device is a child node of the swi...
