Embodiment 4
Based on embodiment 3, below by taking train each compartment there are ten car doors as an example, one is introduced specific for train vehicle
The redundant network system of door:
(1) two MDCU is internally integrated ethernet communication module, is connected with vehicle Ethernet switch, accesses track column
The network of vehicle；Remaining eight LDCU is connected with two MDCU, wherein No. three LDCU are connected with MDCU1, No. four LDCU with
MDCU2 is connected, inside composition CAN network connection structure；
When vehicle Ethernet switch, two MDCU and route all under normal circumstances, two MDCU pass through CAN network collect
The information such as car door fault data, vehicle door status and the software version of all LDCU and adjacent MDCU, then passed by ethernet network
It is defeated by TCMS；All under normal circumstances, two MDCU are connect by ethernet network for vehicle Ethernet switch, two MDCU and route
The information such as control command, temporal information and the vehicle number that TCMS is sent are received, then all LDCU are transmitted to by CAN network；When it
In the Ethernet connecting line of a MDCU occur breaking or when one of vehicle Ethernet switch breaks down, another
MDCU still can continue to carry out data exchange with TCMS, guarantee that the data of all car doors are not lost with other DCU normal communications
It loses, realizes ethernet line redundancy feature；In CAN network, the CAN line between any two DCU breaks, such as
Break between LDCU9 and LDCU10, MDCU1 and MDCU2 then continues and its side DCU for still maintaining physical connection is carried out
Communication, guarantees that the data of all car doors are not lost, and realizes CAN network route redundancy feature.
CAN network connection type: MDCU1 → LDCU3 → LDCU5 → LDCU7 → LDCU9 → LDCU10 → LDCU8 →
LDCU6 → LDCU4 → MDCU2, as shown in Figure 4.
MDCU1 receives the Ethernet data (comprising information such as control command, temporal information and vehicle numbers, similarly hereinafter) of TCMS
Afterwards, be periodically sent in the form of broadcasting CAN network MDCU2, LDCU3, LDCU4, LDCU5, LDCU6, LDCU7,
LDCU8, LDCU9 and LDCU10；After MDCU2 receives the Ethernet data of TCMS, CAN network in the form of broadcasting the period
Property is sent to MDCU1, LDCU3, LDCU4, LDCU5, LDCU6, LDCU7, LDCU8, LDCU9 and LDCU10.
The state of MDCU1, MDCU2, LDCU3, LDCU4, LDCU5, LDCU6, LDCU7, LDCU8, LDCU9 and LDCU10 are believed
The information such as breath, fault message and software version are periodically sent to CAN network in a broadcast manner.MDCU1 and MDCU2 will be from CAN
Network reads these information, and is sent to TCMS5 by ethernet network；Once there is exception in the ethernet line of MDCU1
Network outage both of these case between vehicle Ethernet switch failure and interchanger and MDCU), as shown in figure 5, wherein X is abnormal
Place.
Under this state, the Ethernet data of TCMS by MDCU2 by CAN network be transferred to MDCU1, LDCU3, LDCU4,
LDCU5, LDCU6, LDCU7, LDCU8, LDCU9 and LDCU10；Status information, fault message and software version of all EDCU etc.
Information is sent to CAN network by broadcast mode, and MDCU2 reads these information from CAN, and issues TCMS by ethernet network.
The ethernet line of MDCU2 is abnormal, similarly realizes redundancy feature.Note: the present invention only realizes ethernet line Single Point of Faliure redundancy
Function.
In CAN network, the CAN line between LDCU9 and LDCU10 breaks, as shown in Figure 6:
The information such as status information, fault message and the software version of LDCU3, LDCU5, LDCU7, LDCU9 pass through CAN network
Be periodically sent to MDCU1, MDCU1 receive the Ethernet data of TCMS by CAN network be periodically sent to LDCU3,
LDCU5,LDCU7,LDCU9；The information such as status information, fault message and the software version of LDCU4, LDCU6, LDCU8, LDCU10
MDCU2 is periodically sent to by CAN network.The Ethernet data that MDCU2 receives TCMS is periodically sent to by CAN network
LDCU4,LDCU6,LDCU8,LDCU10.Other CAN node broken strings, similarly realize redundancy feature.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
