Abstract
The utility model discloses one kind interlocking and LEU networking structures, including interlocking and at least one LEU, the interlocking provided with A systems and B systems and one of them be principal series another be for system, the LEU provided with A systems and B systems and one of them be principal series another be for system, also include switch A, switch b, serial server A, serial server B, the switch A and switch b are connected by network with serial server A and serial server B respectively, communicated to connect between the serial server A and serial server B and each LEU.One interlocked in the utility model is that, by A, the mode of B double-network redundants and LEU A, B system communicate, and reliability is higher.
Description
Technical field
The utility model is related to technology of track traffic, more particularly to interlocking and LEU networking technology.
Background technology
As shown in figure 1, in the prior art, passing through the bilateral of RS422 asynchronous serials between interlocking and LEU (LEU)
Road redundant fashion connection, that is, the A systems interlocked and LEU A systems are direct-connected by serial ports, and the B systems of interlocking pass through serial ports with LEU B systems
It is direct-connected.There is following technological deficiency in prior art：
(1) very flexible.
When connecting n LEU, each system of interlocking needs to provide n serial ports, if the existing serial ports number of interlocking is less than n,
The hardware structure for needing change to interlock, flexibility is poor；
(2) availability is low.
1) assume in train travelling process, the A systems of interlocking are principal series, and B systems are standby system, then once any one LEU
A systems connecting line (such as connecting line 1.) failure or LEU A systems failure, will all cause interlocking A to be switched to by principal series for system,
It is to cut improper at the time of being or overlong time availability will be caused to reduce that i.e. the networking plan, which is easily caused to cut,；
If 2) LEU1 A systems and LEU2 B systems break down simultaneously, will cause interlocking A systems and the decision-making of B systems which be for
Principal series, no matter which is for principal series, will all cause LEU1 or LEU2 can not proper communication with interlocking.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of raising flexibility and the interlocking of availability and ground
Face electronic unit networking structure.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that：One kind interlocking and LEU
Networking structure, including interlocking and at least one LEU, the interlocking is provided with A systems and B systems and one of them is principal series
Another is standby system, the LEU provided with A systems and B systems and one of them be principal series another be for system, its feature
It is：Also include switch A, switch b, serial server A, serial server B, the A systems of the interlocking and B systems and interchanger
A, switch b realize communication connection, and the switch A and switch b are taken by network and serial server A and serial ports respectively
Business device B connections, are communicated to connect between the serial server A and serial server B and each LEU.
It is preferred that, pass through RS422 between the serial server A and serial server B and each LEU
Serial mode is connected.
The technical solution adopted in the utility model, interlocking is carried out with LEU by interchanger and serial server
Connection, therefore, has the beneficial effect that：
(1) flexibility is good.
When connecting n LEU, each system of interlocking is only needed to provide 1 network interface, and n serial ports is provided by serial server,
Without because serial ports is excessive and changes the hardware structure interlocked, flexibility is stronger；
(2) availability is high.
1) assume in train travelling process, the A systems of interlocking are principal series, and B systems are standby system, then any one LEU A systems
The A systems failure of connecting line (such as LEU1 connecting line is 1., 3., 5., 7.) failure or LEU, interlocking A systems are possible to normal work,
Will not cause to cut be；
If 2), LEU A systems and another LEU B systems break down simultaneously, interlock also will not cause to cut be, with
All LEU can proper communication；
3) the one of interlocking is that, by A, the mode of B double-network redundants and LEU A, B system communicate, and reliability is higher.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and detailed description：
Fig. 1 is networking structure figure in the prior art between interlocking and LEU；
Fig. 2 is the networking structure figure between the utility model interlocking and LEU.
Embodiment
As shown in Fig. 2 a kind of interlocking and LEU (LEU) networking structure, including interlocking and at least one ground
Electronic unit, the interlocking provided with A systems and B systems and one of them be principal series another be that, for system, the LEU is set
Have A systems and B systems and one of them be principal series another be standby system, in addition to switch A, switch b, serial server A, serial ports
Server B, A systems and B systems and switch A, the switch b of the interlocking realize communication connection, the switch A and interchanger
B is connected by network with serial server A and serial server B respectively, serial server A and serial server B and each LEU
Between connected by RS422 serial modes.
So, interlocking is connected by network with interchanger and serial server, and serial server passes through serial ports and LEU phases
Even, this kind of method hardware structure is more flexible, and is avoided that it is that availability is higher frequently to cut；Interlocking is often by double-network redundant side
Formula is connected with LEU, and the network reliability of redundancy is higher.
Claims (2)
1. one kind interlocking and LEU networking structures, including interlocking and at least one LEU, the interlocking are provided with A systems and B
System and one of them be principal series another be standby system, the LEU is provided with A systems and B systems and one of them is another for principal series
One is standby system, it is characterised in that：Also include switch A, switch b, serial server A, serial server B, the interlocking
A systems and B systems communication connection is realized by network and switch A, switch b, the switch A and switch b lead to respectively
Cross network to be connected with serial server A and serial server B, the serial server A and serial server B and each ground electricity
Communicated to connect between subelement.
2. a kind of interlocking according to claim 1 and LEU networking structures, it is characterised in that：The serial server A and string
Connected between mouth server B and each LEU by RS422 serial modes.
