Description
Technical field
The present invention relates to rail vehicle and communication technical field, particularly to the reconnection communication system of a kind of heavy train groups
System.The invention still further relates to a kind of heavily connection train groups including above-mentioned reconnection communication system.
Background technology
Along with the development of China's mechanical industry, increasing plant equipment is used widely.
Automotive industry is the pillar of mechanical industry, generally can be divided into locomotive and automobile industry.Wherein, the kind of locomotive is very
Many, including passenger traffic goods train, motor-car, high ferro, subway, light rail etc..The carrying capacity of locomotive is a lot, and speed is high, safety
Good, therefore often as the main path of long-distance transportation.
In trunk railway electric propulsion runs, a locomotive traction the most often can not meet the requirement of transport, just needs
Want multi locomotive traction, use multi locomotive traction that the handling capacity of circuit can be made to be greatly increased, improve the economic indicator of railway transportation.Weight
Train in binding group, for ensureing train safe, being efficiently completed operation and task, it is desirable to locomotive shares row by heavily networking network
Car state and the information of control.
At present, locomotive double heading communication mode typically has two kinds, i.e. rigid line heavily joins and heavily joins with wired dedicated network.
Wherein, rigid line heavily joins mode and is weighed on line cable networking by train switch amount, and the information between train and train is led to alternately
Cross the on-off model sent and gather on rigid line to complete.This heavy mode realizes simply, and repair and maintenance is convenient, but due to rigid line
The Limited information of on-off model transmission, it usually needs arrange that a lot of rigid line can increase production as network of heavily networking, circuit increase
Cost, time and materials, reduces the reliability heavily joining train operation, is also required to design extra DI/DO passage simultaneously.This is heavy
Mode heavily joins state recognition generally only as most basic train, and it is heavy that the train that the most substantially be there is a need to heavily join is designed with this
Connection mode.
And wired dedicated network heavily joins, using the such as communication modes such as MVB, RS232, RS485, communication network is by private communication

Device dispels the heat.Meanwhile, for improving radiating efficiency, the present embodiment is also provided with heat conduction bolt 13 on the sidewall of shell 11, and this is led
Hot bolt 13 is fixture, can run through and insert into the inner from the sidewall of shell 11, owing to self material is good heat carrier, and energy
Enough heats by internal component generation are directly delivered to outside shell 11 dispel the heat.
It addition, the present embodiment is provided with multiple communication interface 14, the class of these communication interfaces 14 on reconnection communication device 1
Type is numerous, can meet the interface type on the train of different model.Further, the present embodiment is respectively provided with in each communication interface 14
Electro-magnetic screen layer, so will make reconnection communication device 1 possess good capability of electromagnetic shielding.
Moreover, for providing versatility and interchangeability, the counterweight UNICOM T unit in the present embodiment of reconnection communication device 1
1 have employed reconnection communication control strategy.To this end, the present embodiment is additionally arranged matching module, this matching module is mainly used in by knowing
Each train is dynamically organized into groups by the key message of other train, thus reaches automatically to read and heavily join the quantity of marshaling, car
The information such as type, license number, realizes detecting real-time function simultaneously, enters the heavily connection train marshalling list after any time addition or running train
Row Auto-matching, numbering.
Concrete, the control strategy of matching module counterweight UNICOM T unit 1 is as follows:
Equipment init state is " marshalling " state, does not organizes into groups state train with cycle T 1 for interval by this car information bag
It is sent in heavily binding group network；
" do not organize into groups " locomotive of state, after receiving the information that his car sends, extract some information in this information bag (as
Vehicle, the unique identification information such as license number) it is recorded as " previous stage " train information, meanwhile, to heavily binding networking after the T2 time
Network sends this car information.If this sends successfully, then this locomotive is changed to " organizing into groups " state, if this send successfully it
Before, receive the packet of other heavy trains, then extract the information in this packet, be designated as " previous stage " train information, meanwhile,
In heavily binding group network, this car information is sent again after the T2 time.If being received again by packet, then repeat this operation, until
Send successfully, till changing this car state,.
" organize into groups " train of state after the information bag receiving first " non-previous stage " train, extract in this information bag
Information be recorded as " non-previous stage " train information.After " non-previous stage " train information record, information is latched, follow-up no longer remember
Record other train informations.
" organize into groups " train of state after receiving " previous stage " train information bag, arrange be ready for sending be labeled as true, warp
In heavily binding group network, this car information bag is sent after spending the T3 time.Transmission labelling is changed into vacation after sending successfully.
" organizing into groups " train of state and do not receive his car information bag any within the T1 time, will change this car state is " not
Marshalling " state, remove " non-previous stage " and " previous stage " train information.
" organizing into groups " and carry out record when the train of state receives " non-previous stage " train information bag each time, record is " before non-
One-level " train information bag " reception number of times ", after the train of " organizing into groups " state is successfully transmitted this car information bag, this " is received secondary
Number " clear 0；Marshaling monitors this " reception number of times " in real time, if " reception number of times " 1 should be more than, then shows that this car is not heavily joining
In marshalling, need to change this car state is " marshalling " state, removes " non-previous stage " and " previous stage " train information.
" organize into groups " train of state after receiving " previous stage " train data bag, before being successfully transmitted packet, receive
Arrived other train data bags, then changing this car state is " marshalling " state, removes " non-previous stage " and " previous stage " train
Information.
Wherein, cycle time, T1 ＞ T3 ＞ T2, and was typically on-fixed value, can in specific interval change at random.When
So, T1, T2 and T3 are that fixed value is the most feasible.
It addition, the control strategy of matching module is not limited in foregoing, the most also can heavily join grouped columns according to reality
The situation of car and carry out corresponding amendment, and it be also possible to use the process data of " fixed cycle+life signal " of supporting collision detection
Mode communicates.
The present invention also provides for one and heavily joins train groups, leads to including many trains interconnected with for realizing each train
The reconnection communication system of letter, wherein, this reconnection communication system is identical with foregoing, and here is omitted.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
