Abstract

The invention relates to a multi-path 1553B bus optical fiber relay device and a multi-path 1553B bus optical fiber relay method, and belongs to the technical field of computer communication 1553 buses. According to the invention, multi-path 1553B bus relaying is realized. A relaying scheme can be provided for at most four paths of 1553B buses or four redundant 1553B buses, the communication distance is increased, and the number and the weight of cables are reduced. According to the invention, different signal states and half-duplex states of the four 1553B buses can be effectively distinguished and realized, the scheme is simple, and the realizability is strong. According to the invention, the multi-path 1553B bus relay method and the multi-path 1553B bus relay device are realized by onlyusing two optical fibers, so that the method and the device are economical and efficient. According to the invention, a method for realizing multi-path 1553B bus relay by only using two optical fibers is adopted, so that the weight of the cable is reduced, the cable is not interfered by electromagnetic interference, and the transmission distance is greatly increased.

Description

technical field [0001] The invention belongs to the field of computer communication 1553 bus technology, and in particular relates to a multi-channel 1553B bus optical fiber relay device and method. Background technique [0002] MIL-STD-1553B time-division command / response multiple data transmission bus protocol (1553B), is an aviation system communication bus standard formulated by the US military in 1978. It has the advantages of good real-time performance and high reliability. All kinds of military and civilian aircraft, as well as tanks and warships have performed extremely well. The 1553B bus uses a command / response communication protocol with a transmission rate of 1Mbps, a protocol word length of 20 bits, an effective data bit length of 16 bits, a maximum information length of 32 words, and a half-duplex mode of transmission. In order to further improve the reliability of the application system, the 1553B bus can also be designed redundantly at the system design leve...
