Description
Technical field
The present invention relates to a kind of MVB network architecture method and network structure, be particularly suited for urban rail car
?.
Background technology
According to the applicant understood, along with the fast development of urban track traffic, to city rail vehicle Train Control with
The requirement of monitoring system is more and more higher, particularly to the requirement of Train Control and the control of monitoring system also
More and more, once train network fault, not only affect the normal operation of train, also will affect train
Safety.The most how the reliable train network of design safety is current all carshops and systems provider
The most important thing.
At present, the MVB train network framework on city rail vehicle is required to use repeater, but one
Denier generation relay failure, these network architectures or partial failure, or all lost efficacy, train can only
Enter urgent traction mode, greatly reduce the availability of vehicle.
Summary of the invention
The technical problem to be solved is: overcome the problem that prior art exists, it is provided that a kind of MVB
Bus network framework method and network structure, can i.e. guarantee higher reliability with less equipment, even if
Repeater breaks down and still can implement to control to non-faulting vehicle, is greatly increased the availability of vehicle.
The technical scheme that the present invention solves its technical problem is as follows:
MVB network architecture method, is characterized in that, comprises the following steps:
The first step, in each drivers' cab and each middle car, set repeater respectively, repeater to inner with should
Each subsystem of drivers' cab or this middle car communicates to connect through vehicle grade MVB；Vehicle grade MVB
Only it is distributed in inside drivers' cab or the middle car of correspondence；
Second step, by each drivers' cab, each middle car repeater to outer end respectively with train level MVB
Communication connection；Train level MVB walks each middle car, and its end is positioned at each drivers' cab；
3rd step, in each drivers' cab, by train central control unit, driver display unit and train level
MVB communicates to connect；
4th step, the train central control unit of a drivers' cab, driver display unit are total through train level MVB
Line and the train central control unit of another drivers' cab, driver display unit exchange data；Each drivers' cab
Train central control unit, driver display unit are successively through train level MVB, repeater, vehicle grade
MVB exchanges data with each subsystem；When repeater normally works, the train central authorities control of each drivers' cab
Unit processed, driver display unit normal process data；When repeaters fail, the row of each drivers' cab
Car central control unit, the particular location of driver display unit alarm failed repeater.
Present invention also provide that
MVB network structure, is characterized in that, including train level MVB and vehicle grade MVB；
Train level MVB walks each middle car, and its end is positioned at each drivers' cab；Vehicle grade MVB
Only it is distributed in inside drivers' cab or the middle car of correspondence；Each in each drivers' cab of train, in each middle car
Subsystem respectively through vehicle grade MVB and this drivers' cab or this middle car repeater to inner communication link
Connect；Each drivers' cab, each middle car repeater to outer end respectively with train level MVB communicate to connect；
In each drivers' cab, train central control unit, driver display unit communicate to connect with train level MVB.
The technical scheme that the present invention is the most perfect is as follows:
Preferably, in drivers' cab or middle car, each subsystem is connected in parallel in vehicle grade MVB.
Preferably, train central control unit or driver display unit have remote input output module, far
Journey input/output module have at least 64 railway digital amount input ports, at least 8 road analog input ports,
At least 16 railway digital amount output ports, at least 4 road analog output ports.
The present invention is by setting up vehicle grade MVB and train level MVB, and train central authorities is controlled
Unit is located at vehicle grade MVB, repeater is located at train level MVB, thus goes out at repeater
In the case of existing fault, only lose the supervision to repeater fault car and control, without whole row
Car enters urgent traction mode, it is ensured that the availability of vehicle.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention Organization Chart, and in figure, VCU is train central control unit, and DDU is driver
Display unit, Repeater is repeater, and SUBS1-SUBSn is subsystem.
Detailed description of the invention
It is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments to the present invention.But the present invention is not
It is limited to given example.
Embodiment
The MVB network architecture method of the present embodiment, comprises the following steps:
The first step, in each drivers' cab and each middle car, set repeater respectively, repeater to inner with should
Each subsystem of drivers' cab or this middle car communicates to connect through vehicle grade MVB；Vehicle grade MVB
Only it is distributed in inside drivers' cab or the middle car of correspondence；
Second step, by each drivers' cab, each middle car repeater to outer end respectively with train level MVB
Communication connection；Train level MVB walks each middle car, and its end is positioned at each drivers' cab；
3rd step, in each drivers' cab, by train central control unit, driver display unit and train level
MVB communicates to connect；
4th step, the train central control unit of a drivers' cab, driver display unit are total through train level MVB
Line and the train central control unit of another drivers' cab, driver display unit exchange data；Each drivers' cab
Train central control unit, driver display unit are successively through train level MVB, repeater, vehicle grade
MVB exchanges data with each subsystem；When repeater normally works, the train central authorities control of each drivers' cab
Unit processed, driver display unit normal process data；When repeaters fail, the row of each drivers' cab
