5, the Redundant backup technology can also be used for realizing the broadcast of scheduling guest room, the scheduling urgent intercommunication function of passenger.
Description of the drawings
Fig. 1 is the system structure diagram of the utility model；
Wherein 101 be vehicle-mounted interchanger, and 201 be semaphore, and 301 be Vehicle mounted station, and 401 be connection Vehicle mounted station and vehicle-mounted exchange
The Ethernet of machine, 501 be In-vehicle networking.
Specific implementation mode
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is a part of the embodiment of the utility model, rather than whole embodiments.Based on the embodiments of the present invention, originally
The every other embodiment that field those of ordinary skill is obtained without making creative work should all belong to this
The range of utility model protection.
As shown in Figure 1, a kind of Vehicle mounted station redundancy backup system based on In-vehicle networking, including Vehicle mounted station 301, it is described
Vehicle mounted station 301 is installed in the drivers' cab cabinet at vehicle both ends, the Vehicle mounted station 301 and control centre's transmitting scheduling information,
The system further includes vehicle-mounted interchanger 101 and In-vehicle networking 501, and the Vehicle mounted station 301 at the vehicle both ends is mutually redundant hot standby
Part, the Vehicle mounted station 301 connects In-vehicle networking 501 by vehicle-mounted interchanger 101, and the Vehicle mounted station 301 passes through vehicle-mounted net
501 mutual transmitting scheduling information of network.
The Vehicle mounted station 301 includes signal acquisition and playback terminal and semaphore 201, in the semaphore and scheduling
Heart transmitting scheduling information, the signal acquisition and playback terminal are acquired and are played by In-vehicle networking transmitting scheduling information
Scheduling information.
The Vehicle mounted station 301 and vehicle-mounted interchanger 101 carry out point-to-point connection by Ethernet 401, described two
The signal acquisition of Vehicle mounted station 301 is in consolidated network address field with playback terminal.
The In-vehicle networking 501 is to be used for transmission big data quantity, non-security, non-pass inside a kind of rail traffic vehicles
The private communication Ethernet of bond type data.
The scheduling information includes short data interaction, traffic order, speech talkback and the video of driver and control centre
Intercommunication.
The Vehicle mounted station 301, which divides, is：It is activated end Vehicle mounted station, no department to have the Vehicle mounted station of one end drivers' cab residing for driver
