Description
Technical field
This utility model relates to technical field of rail traffic, particularly relates to the locomotive comprehensive wireless of a kind of dual CAN bus
Communication equipment.
Background technology
(Cab Integrated Radio communication equipment, locomotive comprehensive wireless leads to train CIR at present
Letter equipment) each Main functional units of main frame needs CAN (Controller Area Network) bus to carry out even to it
Connect, and CAN carries data and two kinds of channel transfers of voice.
On CIR, CAN has following defects that at present
1) integrity problem.Modules unit is attached by CAN, is responsible for data transmission, is equivalent on CIR
The major trunk roads that information is mutual, if there is any exception in trunk, then whole link network is at dead state, it is impossible to enter
Row 450M, GSMR call conversation, GPS equipotential, the inquiry of row tail is mutual, and traffic order receives and unlimited running number sends
Etc. all of work.A time train so can be caused to receive and send messages, carry out parking process.
2) issue handling mode is single.Occurring in that CAN problem, first processing mode is that whole equipment of CIR carries out weight
Open, do not recover to carry out parking carry out whole equipment replacement of CIR if restarted, if distance engineering section is far,
Then taking long enough to carry out etc. to be replaced, manpower and materials spending is the biggest.

Figure.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into protection domain of the present utility model.
The structural representation of the cab integrated radio communication of a kind of dual CAN bus that Fig. 1 provides for this utility model embodiment
Figure.As it is shown in figure 1, it specifically includes that
CAN interface converting unit 1 and connected voice unit, main control unit, satellite positioning unit, standby control list
Unit, CAN interface converting unit 2 and connected data cell, communication unit 1, communication unit 2, record unit,
WiMAX unit, power supply unit, power bus, CAN 1 and CAN 2；Wherein:
Power supply unit outfan is connected with power bus, this power bus the most respectively with CAN interface converting unit 1, master control list
Unit, satellite positioning unit, standby control unit, CAN interface converting unit 2, communication unit 1, communication unit 2, record unit
And WiMAX unit is connected；
Described main control unit by CAN 1 and CAN 2 respectively with CAN interface converting unit 1, satellite fix list
Unit, standby control unit, CAN interface converting unit 2, communication unit 1, communication unit 2 and record unit are connected.
Additionally, also include: industry ethernet, WiMAX unit and Switch Interface Unit；
Described main control unit by industry ethernet respectively with described WiMAX unit, Switch Interface Unit, record unit
And be connected for control unit；

It will be understood by those skilled in the art that and after some unit above-mentioned, bus 1,2 be only used for distinguish；And Fig. 1
In CAN (leading), CAN (from) be also only used for distinguishing two CAN, its master slave relation can basis
Practical situation determines.
Principle in the above-mentioned cab integrated radio communication of this utility model embodiment is as follows:
1) dual CAN bus redundancy technology normal mode of operation
Under normal mode of operation, two CAN duties are normal, and wherein a CAN is transmitted for data,
Another root CAN is used for voice transfer；Further, main control unit the work shape of these two CAN is monitored in real time
State.If a certain CAN continuous several times sends data (or voice) failure, then it is assumed that there occurs CAN event
Barrier；Now, send, to unit, the message that CAN breaks down by another root CAN, and enter standby
Mode of operation.
2) dual CAN bus redundancy technology standby operating mode
After entering standby operating mode, under the coordination of control unit, the normal CAN of duty carry out data
With the transmission of voice, and automatically reduce timing duplicate message transmit frequency, reduce to the biography in CAN after system degradation
Transmission of data pressure.
Meanwhile, main control unit also tentative can carry out CAN recovery, if it occur that the CAN of fault is just being recovered
Often, then main control unit broadcast CAN replys normal message, and unit receives CAN and recovers message, automatically
Return normal mode of operation.
The cab integrated radio communication that this utility model embodiment provides uses dual CAN bus redundancy technology, makes simultaneously
By two CAN, a responsible data transmission, a responsible voice transfer, when some CAN breaks down
Time, carrying out degradation process, normal CAN undertakes data and voice two kinds, it is possible to detection recovers, and improves and sets
Standby reliability, real-time and stability, ensure that train can normally even running.
