Description
Technical field
The utility model relates to communication technique field, refers more particularly to a kind of 1553B bus communication module based on Ethernet.
Background technology
MIL-STD-1553B bus is called for short 1553B bus, is interior of aircraft time-devision system command/response formula multiplexed data bus.1553B data bus standard is a kind of serial multiplex data bus standard that 20 century 70s are announced by the U.S., adopt instruction/response type communication protocol, it has three kinds of terminal types: bus control unit (BC), remote terminal (RT) and bus monitor (BM); Information format have BC to RT, RT to BC, RT is to RT, broadcast mode and system control mode; Transmission medium is Shielded Twisted Pair, and 1553B bus coupling mode has direct-coupling and transformer coupled; 1553B bus is multi-redundant bus type topological structure, has transmitted in both directions characteristic, and its transmission speed is 1Mbps, and transmission means is half-duplex mode, adopts Manchester code to carry out coding transmission.Adopt this coded system to be because be applicable to transformer coupled, because direct-coupling is unfavorable for terminal fault isolation, can cause because of a terminal fault paralysis completely of whole bus network, so explicitly point out not recommendation direct coupling system in its agreement.
1553B bus has at a high speed, feature flexibly, and communication efficiency is high, amendment, expansion and easy maintenance.MIL-STD-1553B is digital command/response type, time-devision system multiplex data bus, transmission rate 1M bps, word length 20 bits, data effective length 16 bits; Half-duplex transmission mode, two redundant fault fault-tolerant ways, transmission medium is Shielded Twisted Pair.
The Redundancy Design of 1553B bus, has improved subsystem and system-wide reliability.Bus (comprising bus control unit, twisted-pair feeder, the coupling device etc.) mean time between failures itself exceedes 10000 hours, in total system, substantially can ignore its failure rate, digital transmission mode is compared with traditional mould electricity mode, speed is faster, the reaction time is shorter, confidentiality is better, antijamming capability is stronger, can give full play to Fire Control Equipment performance.Word error rate is less than 1/10000000th.Aspect logistics safeguards, the interface of standard, plug-in card are very easy to dismounting, can be easily by digital instrument test/virtual.One of ground test only after tested, with regard to comparable 30% the maintenance man-hours that reduced in the past.
Ethernet (Ethernet) is a kind of computer HYPERLINK " http://zh.wikipedia.org/wiki/%E5%B1%80%E5%9F%9F%E7%BD%91 " local area network building technology.The IEEE802.3 standard that IEEE formulates has provided the technical standard of Ethernet.It has specified to comprise the content of line, the signal of telecommunication and media access layer HYPERLINK " the http://zh.wikipedia.org/wiki/%E7%BD%91%E7%BB%9C%E5%8D%8F%E8%AE% AE " agreement of physical layer.Ethernet is the local area network technology that current application is the most general.It has replaced other local area network standards to a great extent, as token-ring network (token ring), FDDI and ARCNET.
The standard topology structure of Ethernet is bus-type topology, but current Fast Ethernet (100BASE-T, 1000BASE-T standard) in order farthest to reduce conflict, farthest improve network speed and service efficiency, use switch (Switch hub) to carry out network connection and tissue, like this, it is star-like that the topological structure of Ethernet has just become, but logically, Ethernet still uses the bus conflict technology of bus-type topological sum CSMA/CD (Carrier Sense Multiple Access/Collision Detection is csma/cd).
Traditional 1553B interface board is PCI or CPCI interface, uses the 1553B board of this interface, need to shut down computer, and cuts off the electricity supply, and opens computer cabinet, board is inserted in computer associated socket, then start is used this board.First, nowadays a lot of computers are without PCI slot; Secondly,, while going out to debug, a lot of clients do not wish to open their computer cabinet; Again, the dismounting of the board of this interface is loaded down with trivial details.Therefore, be necessary very much to provide a 1553B bus communication board that does not need to open computer cabinet, computer booting state and can install a kind of computer interface that board, current main flow computer all comprise, and Ethernet interface just meets These characteristics.That is to say, the 1553B bus communication module based on Ethernet interface just meets These characteristics.
