Description
Technical field
The present embodiments relate to train communication technical field more particularly to a kind of separated times of double-unit traction controller
Device and system.
Background technology
Multifunctional vehicle bus (Multifunction Vehicle Bus, abbreviation MVB) is Train Communication Network (Train
Communication Network, abbreviation TCN) a part.MVB is in a vehicle in enclosed train or open type train
The connection of equipment between portion's equipment or the different vehicle of fixed marshalling.MVB includes one or more total segments, using electric appliance short distance
Medium (EMD) the communication network transmission medium different with fiber medium three kinds of (OGF) with a distance from medium (ESD), electric appliance
Any one, by several MVB equipment connect, constitute MVB in a total segment.In the prior art, MVB generally uses
EMD, i.e., twisted-pair shielded wire cable is as communication network transmission medium.
Twisted-pair shielded wire is wound mutually according to certain specification by the conducting wire of a pair of or more than one pair of mutually insulated
Manufactured a kind of communication network transmission medium together.EMD carries out electrical isolation using Shielded Twisted Pair in transformer
In the case of can farthest transmit 200m, operating rate 1.5Mbit/s.Maximum can support 32 equipment in transmission range.
In MVB, in order to realize stronger failure tolerance, in twisted-pair shielded wire cable as communication network transmission medium
In the case of, signal transmission is carried out by the way of medium redundancy.Fig. 1 is MVB equipment in existing double-unit traction controller
Attachment structure schematic diagram.As shown in Figure 1, in the prior art, be attached two MVB equipment by DB9 connectors,
In, it is the twisted-pair shielded wire cable 3 for including two pairs of twisted-pair feeders between two DB9 connectors 1b and 2b, first couple of twisted-pair feeder 3a is along inverse
Clockwise is wound, and second couple of twisted pair wire 3b is wound in the counterclockwise direction, first couple of twisted pair wire 3a and second pair of twisted-pair feeder
Cable 3b is wound in the counterclockwise direction, for a clear description the connection structure of DB9 connectors 1b and DB9 connectors 2b, in Fig. 1 not
It marks each pair of twisted-pair feeder and carries out wrapped anti-clockwise, another two DB9 connectors 1a, 2a are set with the first MVB equipment 1, the 2nd MVB respectively
Standby 2 connection.In Fig. 1,9 of 9 pins of the connector plug of DB9 connectors 1a and DB9 connector 1b connector plugs
Pin is electrically connected, AP the and AN pins of the AP and AN pins of the output end of DB9 connectors 1b and the input terminal of DB9 connectors 2b it
Between pass through first pair of twisted pair wire 3a connection, the input of the BP and BN pins and DB9 connectors 2b of the output end of DB9 connectors 1b
By second pair of twisted pair wire 3b connection between BP the and BN pins at end, 9 pins of the connector plug of DB9 connectors 2b with
9 pins of the connector plug of DB9 connectors 2a are electrically connected, and then are realized between the first MVB equipment and the 2nd MVB equipment
Electrical connection.Wherein, first couple of twisted-pair feeder 3a is used for transmission the main road difference between the first MVB equipment 1 and the 2nd MVB equipment 2
Signal, second couple of twisted pair wire 3b be used for transmission between the first MVB equipment 1 and the 2nd MVB equipment 2 from road differential signal, it is main
Road and from road be the two-way circuit being mutually redundant.When carrying out signal transmission, acquiescence is communicated using main road, when main road occurs
When open circuit or signal are abnormal, switch to from road and carry out signal transmission.
From Fig. 1 in the prior art attachment structure schematic diagram of the MVB equipment of MVB bus, it is known that in the prior art, two
MVB equipment is connected by twisted-pair shielded wire cable, if the biography between two MVB equipment in an intermediate position in MVB bus
Defeated signal is tested, and due to the limitation of MVB connection modes, can only be linked into multiple twin instead of a certain MVB equipment with test equipment
The other end of shielded cable tests the MVB equipment of one end, then the transmission signal of one end MVB equipment is exported from test equipment
It is transferred to next MVB equipment, the process of test is made to stopped the normal communication in a total segment between two MVB equipment,
And since transmission signal is exported from test equipment, so that the transmission signal in MVB bus is generated error, influence to pass in MVB bus
The accuracy of defeated signal.
