The communication means of avionics network system and system disclosed in the embodiment of the present invention, by by procotol abstract, Realize abstract process to each node configuration detail, and by FC-AE-ASM agreement and DDS (Data Distribution Service, data distribution formula services) specification is adapted to it is achieved that in avionics network system bottom-layer design, to nodal community The simplification of configuration process is processed, thus when carrying out the configuration of avionics network system, decreasing the workload of network planning business, and Data Computation Unit and the physical connection of sensor and its physical attribute in bus need not be considered further that, make whole communication process More hommization, thus shortening the nodal community configuration required time, and then shortens the design cycle of avionics network system.

DDS is the New-generation distributed reality that OMG (OMG) formulates on the basis of the standards such as HLA and CORBA When communication middleware technical specification, DDS adopt publish/subscribe architectural framework, emphasize data-centered, abundant QOS be provided Quality of service policy, can ensure data carry out real-time, efficient, neatly distribute, the application of various distributing real communication can be met Demand.The application, by FC-AE-ASM agreement and DDS specification combine, provides a kind of new avionics network system.

The configuration process of avionics network system is specific as follows：

Referring to Fig. 1, a kind of communication means flow chart of avionics network system disclosed in the embodiment of the present invention, the method includes Step:

The required initialization resource of step S101, application present node initialization；

Wherein, described initialization resource at least includes：Resource shared by FC-AE-ASM device hardware and data distribution Formula services the resource shared by data publisher in DDS specification.

In practice, initialization resource can also include：Shared by data write unit corresponding with described data publisher Resource shared by resource, data subscription person and the money shared by data-reading unit corresponding with described data subscription person Source.

Step S102, obtain the configuration information of described present node from the blueprint allocation list pre-seting, according to described just Beginningization resource and described configuration information initialize to described present node；

Wherein, described blueprint allocation list includes：The each boat corresponding with all Aerial Electronic Equipments in actual avionics network system Electric equipment node, is arranged on the communication node on each described Aerial Electronic Equipment node, and communication information between described communication node Message attributes configuration.

The communication node attribute configuration of the device node attribute configuration of each Aerial Electronic Equipment node and each Aerial Electronic Equipment node is The nodal community configuration of whole avionics network system.

Configuration information includes：Message attributes configuration and nodal community configuration.

It should be noted that blueprint allocation list is obtained using blueprint configuration tool, as shown in Fig. 2 the setting of blueprint allocation list The process of putting includes step：

Step S201, the establishment boat corresponding with each Aerial Electronic Equipment that can process FC-AE-ASM message in real aircraft Electric equipment node；

Specifically, each Aerial Electronic Equipment that can process FC-AE-ASM message in real aircraft refers specifically to：Can pass through FC-AE-ASM board or other relevant devices send, receive, process FC-AE-ASM message, and run is embedded operation The Aerial Electronic Equipment of system.

Each the Aerial Electronic Equipment node creating can be communicated by being under the jurisdiction of the communication node of this Aerial Electronic Equipment node, All of Aerial Electronic Equipment node constitutes the Aerial Electronic Equipment collection of currently whole machine, and this Aerial Electronic Equipment collection simulates the avionics of currently whole machine Communication equipment collection.

Step S202, the device node attribute of each described Aerial Electronic Equipment node of configuration, described device node attribute includes：If Standby title and device id；

Specifically, each Aerial Electronic Equipment node simulates one of real aircraft environment physical equipment, therefore for realizing Mutual differentiation between each Aerial Electronic Equipment node is it is necessary to configure corresponding device node attribute to each Aerial Electronic Equipment node.If Slave node attribute includes：Device node title and device node ID (Identification, identity number).Device node Title can be identified using the Chinese being less than 32 characters, and device node ID can use one 32 no symbols Integer is identified.Illustrate, as shown in figure 3, the corresponding device node of equipment 1 is entitled：Sensor device, equipment section Point ID is 1；The corresponding device node of equipment 2 is entitled：Flying control equipment, device node ID is 2；The corresponding device node of equipment 3 Entitled：Navigator, device node ID is 3, and wherein, equipment 2 is located in network 1, and equipment 3 is located in network 2, equipment 1 Common factor part in network 1 and network 2.

Whether step S203, to verify each device node attribute unique in avionics network system；

Specifically, device node title and device node ID be as two attributes of Aerial Electronic Equipment node, in order to identify boat It is unique that each Aerial Electronic Equipment node in electric network, therefore this two attributes preferably must be held in whole avionics network system.To setting The verification of slave node attribute mainly includes three aspect contents：1. whether device node attribute repeats in whole avionics network system； 2. whether device node title is less than 32 characters and containing only Chinese；3. whether device node ID is that 32 no symbols are whole Type numeral.If current device nodal community does not repeat in whole avionics network system, device node title is not above 32 Individual character and containing only Chinese, device node ID is 32 unsigned int numerals simultaneously, then judge that current device node belongs to Property unique in avionics network system.

When certain device node attribute is unsatisfactory for above-mentioned three aspect content, system can export information, to designer Member carries out alarm prompt.

If step S204 all of device node attribute is all unique in described avionics network system, described in each Communication node is created on Aerial Electronic Equipment node；

Specifically, communication node represents the minimal communications unit in FC-AE-ASM communication protocol.In Aerial Electronic Equipment node After the completion of establishment, because the communication between Aerial Electronic Equipment node needs to rely on communication node to realize it is therefore desirable in each avionics Communication node is created on device node.Because the message that each Aerial Electronic Equipment node needs the network service and transmission participating in is born Carry different, therefore, the quantity of the communication node that each Aerial Electronic Equipment node comprises can have difference, but each Aerial Electronic Equipment Node includes at least a communication node, and all of communication node constitutes the communication section point set of avionics network system.Illustrate, As shown in figure 3, sensor device includes communication node 1-1 and communication node 1-2；Flying control equipment includes communication node 2-1； Navigator includes communication node 3-1.

Step S205, the regulation according to FC-AE-ASM agreement, configure the communication node attribute of each described communication node, institute State communication node attribute to include：Communication node title and communication node ID；

Specifically, after the completion of the communication node in avionics network system creates, need for each communication node in FC- Residing network category in AE-ASM network carries out attribute configuration.According to the regulation of FC-AE-ASM agreement, each communication node needs The communication node attribute of configuration includes：Communication node title and communication node ID, communication node title can use the word of 16 bytes Symbol string represents, communication node ID is seen and is identified using 24 unsigned int numerals.Illustrate, as shown in figure 4, passing Sensor device node is provided with two communication nodes, respectively communication node 1-1 and communication node 1-2, and communication node 1-1's is logical Believe that nodename is：Position sensor node, communication node ID is：0x000005；The communication node title of communication node 1-2 For：Height sensor node, communication node ID is 0x000006；Flying control equipment node is provided with a communication node：Communication section Point 2-1, the communication node of communication node 2-1 is entitled：Data computational node, communication node ID is：0x000010.

Wherein, the communication section in avionics network system just can be uniquely determined according to communication node title and communication node ID Point.

Whether step S206, to verify each communication node attribute unique in described avionics network system；

Specifically, communication node title and communication node ID be as two attributes of communication node, in order to identify avionics net Each communication node in network, if communication node attribute repeats to lead to network communication logic chaotic, therefore this two attributes Preferably must be held in whole avionics network system unique.Verification to communication node attribute mainly includes three aspect contents：1. communicate Whether nodal community repeats in whole avionics network system；2. whether communication node title is the character string of 16 bytes；3. communicate Whether node ID is 24 unsigned int numerals.If present communication node attribute does not have in whole avionics network system Repeat, the character string of entitled 16 bytes of communication node, communication node ID is 24 unsigned int numerals simultaneously, then sentence Determine present communication node attribute unique in avionics network system.

When certain communication node attribute is unsatisfactory for above-mentioned three aspect content, processor can export information, for right Designer carries out alarm prompt.

If step S207 all of communication node attribute is all unique in avionics network system, according to actual avionics net Message definition between each communication node in network system, creates the News Category between each communication node；

Specifically, when the verification of all of communication node completes and all unique when, participate in communication in whole avionics network system Object define and complete.At this moment it is accomplished by, according to the message definition between each communication node in actual avionics network system, creating Build the News Category between each communication node.As shown in fig. 5, it is assumed that in true airborne circumstance, positioned at sensor device node Position sensor node need to positioned at flying control equipment node data computational node send location message, highly sensing simultaneously Device node needs to send height message to data computational node, for simulating this scene, creates equipment 1 interior joint 1-1 and sends To the message 1 of equipment 2 interior joint 2-1, and equipment 1 interior joint 1-2 is sent to the message 2 of equipment 2 interior joint 2-1.This In the case of it is meant that the type of message that network 1 interior joint 1-1 is sent to node 2-1 is only message 1, for node 1-1 send Type of message to node 2-1 is not the message of message 1 is then invalid message；In the same manner, node 1-2 is sent to disappearing of node 2-1 Breath type is only message 2, and the type of message being sent to node 2-1 for node 1-2 is not the message of message 2 is then invalid disappearing Breath.

Step S208, according in actual airborne circumstance message arrangement definition, message attributes are carried out to message of all categories Configuration；

Specifically, after the completion of the News Category between each communication node creates, need according in actual airborne circumstance Message arrangement defines, and carries out message attributes configuration to each News Category.The content of message attributes configuration includes：Message content, disappear Breath direction, message priority and message QOS (Quality of Service, service quality) strategy.

Wherein, message content includes：DDS identifier, valid data content and message id.Specifically, DDS identifier is by joining Put software to automatically generate it is not necessary to designer configures.Valid data content refers to the actual physics meaning of whole message data section Justice, the length including whole data segment and the length of each field and meaning.Message id belongs to the category of FC-AE-ASM agreement, For FC-AE-ASM protocol label each to such message definition in whole communication network.

Message direction refers to source place and the destination of this message, and message direction falls within the category of FC-AE-ASM agreement. If when creating message two communication nodes of the designated binding with message and direction, message direction by configuration software from Move and be provided with；If when creating message, message has been bundled on FC-AE-ASM switch, then need designer manual The source place of specified message and destination.

Message priority falls within the category of FC-AE-ASM agreement, by designer, message priority is defined.

Message QOS strategy belongs to the category of DDS, is set according to the QOS of QOS strategy initialization corresponding message by data distribution layer Put.

Illustrate the content of message attributes configuration, as shown in fig. 6, for message 1, (1) message content includes：①DDS Identifier：0x140001；2. valid data content includes：Data length is 8 bytes；Field meaning is longitude -4 byte and latitude Degree -4 bytes；3. message id.(2) message direction includes：Source port ID：0x000005, and destination interface ID：0x000010. (3) priority：Promptly；(4) QOS strategy.

For message 2, (1) message content includes：1. DDS identifier：0x140002；2. valid data content includes：Number It is 4 bytes according to length；Field meaning is height -4 bytes；3. message id.(2) message direction includes：Source port ID： 0x000006, and destination interface ID：0x000010.(3) priority：Promptly；(4) QOS strategy.

Step S209, according to FC-AE-ASM agreement and DDS specification, the correctness of verification message attribute configuration；

Specifically, for whole avionics network system, according to FC-AE-ASM agreement and DDS specification, message attributes should be observed Principle include：1. the ID of message of the same race, DDS identifier should be consistent, the message of different ID, and DDS identifier should be inconsistent； 2. the source port ID and destination interface ID of message should exist in avionics network system；3. each field in valid data content Length sum should be equal to whole valid data segment length in valid data content.

When message attributes are unsatisfactory for above three principle, system can export information, and designer is alerted Prompting.

If the configuration of step S210 message attributes is correct, generates one and comprise all of Aerial Electronic Equipment node, all of logical Letter node and the blueprint allocation list of all of message attributes configuration.

Specifically, after the completion of the configuration of the Aerial Electronic Equipment node in avionics network system, communication node and message attributes, then Generate a blueprint configuration comprising all of Aerial Electronic Equipment node, all of communication node and the configuration of all of message attributes Table.

When initializing to present node, the derivation of the blueprint pre-seting allocation list is obtained portion and comprises blueprint configuration Xml (Extensible Markup Language, the extensible markup language) file of table.Each Aerial Electronic Equipment node can be by reading The blueprint allocation list taking and parsing derivation realizes the initial configuration to communication node and message in this Aerial Electronic Equipment node.

Step S103, according to predefined QOS strategy, the message to be sent of present node after initialization is marked；

Wherein, QOS (Quality Of Service, service quality) refers to a network and can utilize various basic technologies, There is provided more preferable service ability for specified network service, be a kind of security mechanism of network, for solving network delay and resistance A kind of technology of the problems such as plug.

Step S104, whether effectively judge the flag of described message to be sent, if it is, execution step S105；

Specifically, can judge to be sent by judging whether the flag of message to be sent contains default identifier Whether effectively the flag of message, and when the flag determining message to be sent contains default identifier, judges to be sent disappearing The flag of breath is effective.

Step S105, message to be sent is exported to FC-AE-ASM bus；

Step S106, gather other nodes from FC-AE-ASM bus and export the message to FC-AE-ASM bus, and obtain Cancel the identifier ID of breath；

Step S107, the corresponding relation according to the ID of record and subject information in described ID and described blueprint allocation list, sentence Whether described message of breaking is the message that described present node needs to receive, if it is, execution step S108；

Step S108, the subject information according to described message, call corresponding message groups bag task that described message is carried out Process, obtain the corresponding message content of described message.

Wherein, subject information can be speed, position, humidity, temperature etc..

It should be noted that when the message judging to obtain is not then it is assumed that this disappears when present node needs the message receiving Breath is invalid message for present node, in this case it is necessary to filter this message.

In the present embodiment, step S101～step S105 is that present node sends the process of message to FC-AE-ASM bus, Step S106～step S108 is the process obtaining the message that other nodes send from FC-AE-ASM bus, and two processes are permissible Execute simultaneously, and be independent of each other naturally it is also possible to according to actual needs, first control present node first to send out to FC-AE-ASM bus Send message, then obtain, from FC-AE-ASM bus, the message that other nodes send, such as the embodiment shown in Fig. 1 it is also possible to first from FC-AE-ASM bus obtains the message that other nodes send, then sends message to FC-AE-ASM bus.

In summary, the configuration information record of each node in avionics network system is configured by the present invention in advance in blueprint In table, when avionics network system is communicated, based on DDS standard planning, present node is initialized, when each node leads to When crossing FC-AE-ASM bus and carrying out information exchange, obtain required data during information exchange from blueprint allocation list.The present invention is led to Cross and FC-AE-ASM agreement is adapted to DDS specification, make to have carried out abstract and black box to procotol during network design Change, on the one hand accelerate the nodal community configuration to each node, decrease the workload of network planning business, on the other hand set Meter personnel need not consider further that Data Computation Unit and the physical connection of sensor and its physical attribute in bus, but is absorbed in In the message communicating of each communication node, so that whole communication process more hommization, shorten needed for nodal community configuration Time and the design cycle of avionics network system.

For optimizing above-described embodiment further, communication means can also include step：
