Target device, which passes through the communication identification information received, can determine that the sender i.e. target of communication identification information is closed Join equipment, and the mode, that is, destinations traffic mode sent.Since communication identification information has the mark action of equipment, target is set It is standby that the target association equipment for sending the communication identification information can be directly determined according to communication identification information；It can be set simultaneously with target The standby destinations traffic mode that the communication identification information is determined according to the reception mode of the communication identification information or receiving port, this Outside, target device can also be according to the wire communication identification information or channel radio beacon for including in the communication identification information received Information is known to determine the destinations traffic mode of the communication identification information.

It should be noted that target association equipment can use a variety of communications in the communication identification information transmitted and received Mode namely target association equipment can use at least one destinations traffic mode when sending communication identification information.But target is set For when receiving a communication identification information, it can only determine that the communication identification information at current time is by first object communication party What formula was sent；Then if target device receives the communication identification information again, the communication identification letter at current time can only be determined Breath is sent by the second destinations traffic mode, that is to say, that can only determine that a target is logical by a communication identification information Letter mode, wherein first object communication mode and the second destinations traffic mode are identical or different.

S130, the target device is according to the destinations traffic mode of the target association equipment and preset logical Letter mode priority updates the mapping relations between communication mode and associate device.

Specifically, preset communication mode priority can be each in preset at least two communication mode of user lead to The priority of letter mode.Mapping relations between communication mode and associate device are used to indicate target device logical with associate device Communication mode is selected when letter.

In the present embodiment, target device can be obtained according to the mapping relations of updated communication mode and associate device The communication mode currently with the highest priority of the associate device is taken, available communication can be filtered out from communication Mode, and or filter out user from communication and need communication mode (as most reliable or most without geographical restrictions), To realize the communication mode that target device and associate device is adjusted flexibly.

S140, the target device are communicated according to the mapping relations at least one described associate device.

Specifically, target device can determine the communication mode with each associate device according to mapping relations, need with When associate device communicates, the communication mode communicated with the associate device can be obtained based on mapping relations, and obtain the communication party The relevant parameter of formula learns the MAC Address of the associate device, specific: to obtain the MAC Address of associate device, and lead to this is received The corresponding port of letter mode and the MAC Address establish mapping relations, and generate corresponding map entry, are saved in MAC Address column In table.The communication with the associate device is established as a result, is communicated to realize at least one associate device.

On the basis of the above embodiments, target device and at least one associate device can be separately positioned on train In different compartments.In a specific application scenarios, as shown in Figure 1 b, equipment is set, each equipment can lead in each compartment It crosses base station to carry out wireless communication, or wire communication is carried out by Wireline.

In general, the communication mode in train between the equipment of each compartment configuration is wire communication and wireless communication, can Choosing, first communication party formula is wired communication mode, and second communication method is communication.Further, target device The operation for interacting respective communication identification information at least one associate device using at least two communication modes is executed, can wrap Include: target device, which is executed, interacts respective lead to at least one associate device using wired connection port and wireless communication port Believe identification information operation；Target device determines the communication identification information transmitted and received according to the communication identification information received Target association equipment and target association equipment transmit and receive communication identification information when the destinations traffic mode that uses, It may include: the communication knowledge that target device receives target association equipment using wired communication mode transmission by wired connection port Other information；With or target device by wireless communication port receive target association equipment sent using communication it is logical Believe identification information；Wherein, wired communication port and wireless communication port is respectively configured in target device and associate device, and has Line communication port and wireless communication port are mutually isolated.

Embodiment two

Fig. 2 is a kind of flow chart of communication between devices method provided by Embodiment 2 of the present invention, and the present embodiment is with the present invention Further materialization has been made based on embodiment one, and target device has been executed using at least two communication modes and at least one The operation of the respective communication identification information of associate device interaction, is embodied as: target device is periodically executed using at least two Kind communication mode interacts the operation of respective communication identification information at least one associate device；It is same in the mapping relations Associate device corresponds to an age timer；The method also includes: the target device is in the aging for detecting associate device When timing duration in timer meets failure condition, the associate device of failure is deleted from the mapping relations, and will be with The corresponding age timer of the associate device being not present in the mapping relations is purged.

As shown in Fig. 2, this method specifically includes:

S210, target device, which is periodically executed, to be interacted respectively using at least two communication modes at least one associate device From communication identification information operation.

Target device can judge the communication party according to by the way that whether a kind of communication mode receives communication identification information Whether formula is feasible, that is to say, that target device is to judge whether communication line disconnects by interactively communicating identification information, setting Interactive operation is periodically executed, can be asked to avoid still being communicated in the case where communication line disconnects and leading to data degradation etc. Topic can find the communication line disconnected in time, and then be switched to feasible communication line in time, improve the reliability of communication. Wherein, the period can be set according to actual needs, and be not specifically limited to this embodiment of the present invention.

S220, the target device determine that the communication received described in sending is known according to the communication identification information received It is used when the communication identification information received described in the target association equipment of other information and target association equipment transmission Destinations traffic mode.

Wherein, communication identification information, the determination of target association equipment and the determination of destinations traffic mode can refer to upper State the description of embodiment.

S230, the target device is according to the destinations traffic mode of the target association equipment and preset logical Letter mode priority updates the mapping relations between communication mode and associate device；Wherein, in the mapping relations, a pass Join the corresponding age timer of equipment.

Target device needs to carry out before a communication MAC address learning, i.e., by the relevant information of MAC Address (such as source MAC The information such as address, target MAC (Media Access Control) address and corresponding port information) it records, the relevant information based on MAC Address Target device may be implemented and the communication of other equipment (target MAC (Media Access Control) address corresponding equipment).In order to save storage resource, improve Equipment operating efficiency, it will usually which ageing time is set, and after ageing time, MAC Address is not used by always, MAC Address It will be deleted from record.Age timer is for counting ageing time, when the timing duration that age timer is counted reaches old When changing the time, shows the MAC address aging, need to clear up the MAC Address.

Wherein, the mapping relations of the present embodiment can also include the MAC Address of target device, associate device MAC Address, For establishing in the port information and associate device that communicate with associate device for being communicated with target device foundation in target device The information such as port information.

S240, the target device are communicated according to the mapping relations at least one described associate device.

S250, the target device, will be described when detecting that the timing duration in age timer meets failure condition The associate device of the corresponding failure of age timer is deleted from the mapping relations, and will be not present in the mapping relations The corresponding age timer of associate device be purged.

Failure condition can refer to that the timing duration of age timer statistics reaches preset ageing time, work as timing duration When meeting failure condition, show the corresponding MAC address aging of associate device, the associate device can be found from mapping relations simultaneously It deletes, or even information relevant to the associate device in mapping relations (can also be set in such as target device for being associated with this For establishing the port information communicated with target device in the standby port information and the associate device for establishing communication) delete, from And when can fail to avoid communication modes all between target device and associate device, the case where being communicated is continued to, from And it realizes and saves the communication resource.It also needs for age timer to be purged simultaneously, leads to the wasting of resources to prevent timing always.

In the specific implementation process, it can judge that timing duration is in any stage in the implementation procedure of S210-S240 It is no to meet failure condition, mapping relations are constantly updated, therefore, the sequencing of S250 and aforementioned S210-S240 are unlimited.

The embodiment of the present invention is by configuring age timer, the corresponding association of the MAC Address of aging for each associate device Equipment is deleted from mapping relations, to update mapping relations, is avoided in the case where the failure of the communication mode of associate device still The case where continuing communication saves the communication resource, improves flexibility, accuracy and the timeliness of communication mode adjustment.

On the basis of the above embodiments, it can be correspondingly arranged at least based at least two communication modes in mapping relations Two associate device set.Optionally, mapping relations include: the first associate device set corresponding with first communication party formula, with And the second associate device set corresponding with second communication method；The priority of first communication party formula is higher than second communication method Priority.

Specifically, the first associate device set can have with the second associate device set it is overlapping, it can while including phase Same associate device；Can also be entirely different, i.e., do not include identical associate device completely.For example, can be with an associate device It can exist simultaneously in two associate device set, or can only exist in an associate device set.First communication party formula Priority be higher than the priority of second communication method, thus, in succeeding target equipment with associate device when communicate, if The associate device exists simultaneously in two associate device set, and the high communication mode of target device selection priority is associated with this Equipment is communicated, such as first communication party formula.

In a specific example, select the high communication mode of priority may is that target device according to priority from High to Low sequence successively inquires associate device in corresponding associate device set, if inquiring the associate device, It is communicated using the corresponding communication mode of associate device set, to realize in the feasible communication mode of the associate device Obtain the communication mode of highest priority.

In another specific example, the communication mode for selecting priority high may is that target device according to priority Sequence from high to low successively inquires associate device in corresponding associate device set, if inquiring the pass for the first time Join equipment, then it is corresponding in other associate device set to delete the associate device；It is set according to the association of associate device unique match It is communicated for corresponding communication mode is gathered, equally may be implemented to obtain in the feasible communication mode of the associate device preferential The highest communication mode of grade.

It on the basis of the above embodiments, include the corresponding relationship of associate device and age timer in mapping relations, from And configuration age timer is also needed while updating mapping relations, if age timer exists, age timer is updated, If age timer is not present, age timer is established.Due to only when associate device is present in associate device set, the pass Join the corresponding age timer of equipment to exist, to need first to judge whether there is in each associate device set in mapping relations The associate device updates age timer when there are associate device, and when associate device is not present, associate device is added In matched associate device set, and establish age timer.

In another of the invention optional embodiment, target device according to the destinations traffic mode of target association equipment, And preset communication mode priority, the mapping relations between communication mode and associate device are updated, may include: that target is set It is standby if it is determined that destinations traffic mode is first communication party formula, then whether verify in the first associate device set includes target association Equipment；If so, updating the age timer of target association equipment；Otherwise, target is added in the first associate device set to close Join equipment, and the existence of the age timer according to target association equipment, establishes or update the old of target association equipment Change timer；Target device if it is determined that destinations traffic mode be second communication method, then verify in the first associate device set It whether include target association equipment；If so, abandoning the update to mapping relations；Otherwise, it verifies in the second associate device set It whether include target association equipment；If so, updating the age timer of target association equipment；Otherwise, in the second associate device Target association equipment is added in set, and establishes the age timer of target association equipment.

Specifically, the priority of first communication party formula is higher than the priority of second communication method due in mapping relations, If it is determined that target device and the first communication party formula and second communication method of target association equipment are feasible, can only be closed when target When the destinations traffic mode for joining equipment is first communication party formula, age timer is updated, meanwhile, when the target of target association equipment Communication mode be second communication method when, abandon update mapping relations, specially abandon update age timer, and abandon by Target association equipment is added in the second associate device set.

By setting first communication party formula and second communication method, and first communication party formula is corresponded in mapping relations and is set Set the first associate device set, corresponding second communication method is arranged the second associate device set, and based on destinations traffic mode, the The priority of one communication mode and the priority of second communication method update the first associate device set in mapping relations, the Two associate device set and the corresponding age timer of associate device may be implemented excellent based on communication mode and communication mode First grade can determine the communication mode of highest priority for each associate device, so that most suitable communication mode is filtered out, Improve communication reliability.

Optionally, target device is communicated, comprising: target device according to mapping relations at least one associate device It is communicated with the first associate device for including in the first associate device set according to first communication party formula；Target device and second It include removing the second associate device except the first associate device to be led to according to second communication method in associate device set Letter.

Specifically, when target device is communicated at least one associate device, in mapping relations, if it is above-mentioned at least One associate device exists simultaneously in multiple associate device set, can set in the corresponding association of the high communication mode of priority In standby set, the associate device that can be communicated by the high communication mode of priority is obtained.It is subsequent according to from priority height To low order, successively obtains and set in the association that the corresponding associate device set of the higher communication mode of above-mentioned priority is not present It is standby, namely the associate device for not determining communication mode in above-mentioned steps is successively obtained, to realize true for each associate device Determine the communication mode of highest priority, to filter out most suitable communication mode, improves communication reliability.

Optionally, target device is after determining that destinations traffic mode is first communication party formula, further includes: target device is tested Whether include target association equipment, if so, the delete target in the second associate device set if demonstrate,proving in the second associate device set Associate device.

In the present embodiment, target device selects a communication mode for each associate device from communication It is communicated, communication data redundancy and communication resource wave can be caused to avoid being communicated simultaneously using communication The case where taking be based on said circumstances, can the only highest priority in each associate device set where associate device it is logical Retain associate device in the corresponding associate device set of letter mode, and deletes the association in other each associate device set and set It is standby.In this way in the communication process of target device and at least one associate device, each associate device only retains a communication party Formula, to avoid the appearance for filtering out the communication mode of highest priority from the corresponding viable communication mode of each associate device The situation of mistake improves the accuracy that communication mode determines, while can reduce the subsequent communication party for judging associate device one by one The step of formula, improves the efficiency that communication mode determines.

Optionally, target device is communicated according to mapping relations at least one associate device, may include: target The third associate device for including in equipment and the first associate device set is communicated according to first communication party formula；Target device with The 4th associate device for including in second associate device set is communicated according to second communication method.

Specifically, only being deposited in all associate device set after passing through the step of deleting duplicate associate device In an associate device, that is to say, that the associate device in each associate device set is all different, thus, when the first association is set There are when third associate device in standby set, third associate device is not present in the second associate device set；When the second association is set There are when four associate devices in standby set, the 4th associate device is not present in the first associate device.It is possible thereby to accurately be associated with One-to-one relationship is established between equipment and communication mode, improves the accuracy that communication mode determines.
