Specific embodiment
Describe detailed features and advantage of the invention in detail in a specific embodiment below, content is enough to make any
Skilled in the art realises that technology contents of the invention and implementing accordingly, and according to specification disclosed by this specification, power
Benefit requires and attached drawing, skilled person readily understands that the relevant purpose of the present invention and advantage.
Train joins again when again, it is preferred that emphasis is identification train joins state, and after identification state, after enabling and activating connection again
Head/tail end equipment controls train.
Fig. 1 shows the Typical Disposition of the cab signal system of fixed marshaling.For fixed marshaling, usual both ends
Respectively configure a set of two and multiply two signalling arrangements (cab signal cabinet as shown in Figure 1) for taking two, when normal work, activated end according to
Fixed marshaling parameter calculates and controls train, while periodically communicating with inactive end, it is ensured that train is when changing end
Consistency on messaging.
After two trains are hung together, system, which is required to identify, hangs together attribute and train marshalling list type, hangs together rear newly organized
Group train starts the calculating and control of being responsible for train operation for the equipment in both ends headstock, it is therefore desirable to again according to marshalling type
It loads the data of new marshaling and establishes both ends communication.
And centrally located two signalling arrangements for hanging together headstock (will not be responsible for train operation and control after hanging together
202) non-controlling equipment, such as 201 in Fig. 2 and is not required to participate in the calculating and control of new marshaling, should exit calculating and control
Work, conflict caused by the device power in order to prevent, this programme, which is taken, automatically powers off processing, it is ensured that the equipment thoroughly exits work
Make.
Fig. 2 shows trains according to an embodiment of the invention to join schematic diagram again.Train joins again after, in hanging together in rear train
Between two signal system equipment (201,202) of position automatically power off, exit work.Join again after, new head end and tail end equipment
Start to communicate and work.Meanwhile cab signal system (updates train length, vehicle parameter, stops according to the Train Parameters join again after
Vehicle point information etc.) calculated and run control.It is described in detail from design on hardware and software individually below.
Hardware design
It is to carry out hanging together a group volume by hitch that train joins again, in order to guarantee the system availability join again after, it is necessary to using electricity
Hook connects device is joined transmission to necessary control or signal of communication again.
1) type of train identifies
According to existing market demand, system solution supports the two different types of trains of column are hung together to join again.What system was supported
Join type again and signal identification logic be as shown in table 1:
1 train of table joins type again
In the present invention, the Vehicle Interface Unit of vehicle provides two-way hard signal (also known as type of train identification letter
Number), i.e. signal A and signal B, and it is sent to cab signal system, cab signal system is identified according to this two-way hard signal
Join type again.In one embodiment, hard signal can be DC110V.
When not having train to join again, signal A and signal B are not activated, activation signal A, two column B two column A type trains join again when
Activation signal B type train joins again when, a column A type and a column Type B train activation signal A and B simultaneously when joining again.
Activation acquires the above two-way hard signal to induction signal, vehicle-mounted signal device when being connected by electric hook connector, uses
Join type again in identification.
It is related to the traffic safety of train since train is hung together, this two paths of signals need to be defined as by cab signal system
Safe input signal.
2) non-controlling device powers down
When two trains are hung together, the power supply of non-controlling equipment is closed by disconnecting relay contact, it is ensured that non-controlling equipment
Exit work.
Fig. 3 shows power supply excision schematic diagram according to an embodiment of the invention.The Vehicle Interface Unit offer is believed all the way
Number relay is hung together for activating or disconnect, when train joins again by disconnecting relay contact, close the work of non-controlling equipment
Make power supply.
3) communication signal transmissions
In order to realize the communication end to end after train joins again, need to transmit signal of communication (such as Ethernet), when two trains are hung together
Afterwards, hitch connector connects the signal of communication of two trains, as shown in Figure 4.
Both ends signalling arrangement is communicated by above-mentioned connection type, is set simultaneously because closing non-controlling in hardware design
Standby power supply, two trains will not cause network conflict when configuring using identical internal network.
In one embodiment, can be as needed, comprehensively consider the limitation and reconnection train of communications cable transmission range
Length etc., increase signal amplifier in the suitable place of train.
Software design
Signal system software is for reconnection train, and it is not necessary to modify application software, it is only necessary to be loaded according to type of train different
Train data, and communicated with suitable equipment.Just it is able to satisfy the normal calculating and control of reconnection train.
1) judge type of train
Application software judges which kind of state train is in by hardware type of train identification signal.
2) data load
The data of all possible compartment class type trains of cab signal system fixed storage route.When software judges train weight
After joining type, matching train data is loaded.Signal system carries out calculating and Train Control according to new train data.
3) it communicates end to end
Train joins again after, original opposite equip. (such as signalling arrangement among two column coupled trains), which needs to power off, is exited
Work, the new needs of equipment end to end re-establish communication connection, start the operation and control of being responsible for train.
By top-down Top-Down Design process, after completing system design, hardware design and software design, system can
Normal operation have and train is supported to join again after.
