Fig. 2 is the Business Stream for the communication interconnection method in Heterogeneous simulation system according to the preferred embodiment for the present invention
Journey schematic diagram.Below with reference to Fig. 2, the detailed process for method that the present invention will be described in detail.
1, configuration is read
Configuration file can be considered that a bridge joint scheme, including the configuration of Heterogeneous simulation System Agent node and bridging rule are matched
It sets:
(1) agent node configures: configuration Heterogeneous simulation System Agent information.By taking HLA13 as an example, agent node is needed to configure
Information have (federal title, federal member title, federation define file FOM, that is, FED file).
(2) bridging rule configures: the data corresponding relationship between the agreement that configuration Heterogeneous simulation system uses.With HLA13 and
For TCP, aircraft entity plane is defined in HLA13 FED file, attribute has pos and name；It is defined in TCP structure
Tplane, member have position and lable.Aircraft is both defined in HLA13 and Transmission Control Protocol, and has position and title two
A attribute, but title is different.
Bridging rule is to establish Data Bridge relationship between the agreement that two heterogeneous systems of HLA13 and TCP use, and can also be claimed
Make mapping relations i.e.:
Plane.pos and tplane.position；
Plane.name and tplane.lable.
2, creation agency
After reading configuration step, the configuration information of isomery agency is obtained, to create agency.Agency is a kind of soft
Part design pattern is commonly used to be packaged complex object and simplify.Agency in Heterogeneous simulation system is assisted to hetero-com-munication
The encapsulation of view, the corresponding communication protocol of an agency.The heterogeneous protocol supported at present has HLA13, HLA1516, TENA, DDS,
SOCKET.The configuration of agency difference, such as HLA13 MAK RTI according to the difference of agreement is mainly configured with (1) connection
Nation's title, (2) federal member title, (3) FED file (define FOM SOM) in this document.And the pRTI of HLA1516 in addition to
Above three configuration, will also there is (4) server ip address and port numbers.
Proxy configurations are obtained, and using these configurations, agency creation factory are called to create agent object.
Agency's not only communication function, also has data management effect, in each agency, can all have one it is remotely right
As list is issued in reflection list and native object.Wherein, the function of the remote object reflection list is to be communicated by proxy call
Interface creation, with the data item update received；The function of the native object publication list is to call generation by bridge joint processor
It manages interface creation and is updated with the attribute of reflective object.
3, buffer area is created
Buffer area, that is, memory buffer, it is interim to save the data and the data that agency called to send that agency submits.This
The Heterogeneous simulation system of invention uses multithreading, handles data collection sum number respectively to improve software treatment effeciency
According to bridge joint.
Each agency can call buffer area, and the data for calling communication protocol interface to collect are encapsulated as event object and are mentioned
It is sent to buffer area.Event in buffer area is by an individual thread process, each event is by corresponding processor, processing
Person can call bridging rule management, be transferred to data in another agency from an agency according to bridging rule.
Each of Heterogeneous simulation system communication middleware agency is internal to have a transmission buffer area, and each agency is also
Share a reception buffer area.If any N number of agent object, there will be N+1 buffer area, (wherein N number of is transmission inside agency
Buffer area and a public reception buffer area).
4, bridging rule management
Bridging rule configuration has been introduced in (2) of above-mentioned steps 1, is that the mapping in heterogeneous protocol between data item is closed
System.Bridging rule management creates bridge joint object when running according to bridging rule, by the maps data items relationship between heterogeneous protocol
Mapping by character string to being converted between integer pair.An interface is provided when tunneling is acted on behalf of by data object sum number
Integer handle is converted to by character string according to item, therefore, after acting on behalf of object initialization, bridging rule management calls each agency to connect
Mouthful, the title of data object and data item that bridging rule uses is substituted by handle.Inquiry string is than inquiry integer consumption
When, and complexity is variation.
5, time series management
Time series management process in the present invention is optional step.The time series management is specific by following two
Step is realized:
(1) it unites and services when, push the time to each Heterogeneous simulation system accessed；
(2) filter data is crossed, according to the timestamp that data reach, wherein being less than the data of current+look-ahead time will be lost
It abandons.
6, data collection
Each above-mentioned agency is encapsulation to communication protocol communication logic, provide data to upwards the asynchronous notifications reached and
The interface of data is sent, and shields the communication logic of internal complexity.Data can notify upper layer in the form of event when reaching.
Upper layer application obtains data by way of registered events processor.Event is predefined, the object hair of each agency
The events such as existing, object is deleted, object properties update, interaction.
7, processing receives buffer area
By above-mentioned introduction it is found that all act on behalf of shares a reception buffer area.Processing receives buffer area in the present invention
Specific processing step is as follows:
(1) judge whether buffer area is sky, is then blocked if it is sky；
(2) if being not sky, an event is taken out from stem；
(3) the processing logic of the corresponding processor of event is called；
(4) deletion event；
(5) step (1)-(4) are repeated, and are so recycled.
8, Data Bridge
During the above bridging rule management processing, by bridging rule by character string to being converted to integer handle
It is right.When to the encapsulation of each agency, the publication of data object, deletion, attribute use handle when updating.
Data Bridge logic is realized in event handler, by taking attribute updates as an example: acting on behalf of the attribute of 1 object A.b more
A update event can be generated when new, and (object handle 10, attribute handle are that 100), Data Bridge logic can be right according to agency 1
As handle and attribute handle are key, the corresponding bridge joint mapping relations list of inquiry, then further according to Proxy Name, object handle
Attributes object is searched with attribute handle and is updated with the data of A.b.
9, processing sends buffer area
In the treatment process of above step 8, sends buffer area and be updated, in a bridge joint process cycle, can traverse
The data item in buffer area is sent, has changed if data item is arranged to data or when dirty data, has called proxy interface
Send the data item.
10, data are sent
The transmission interface of agency is called to send data.The transmission interface of intrinsic call communication protocol is acted on behalf of by the proxy management
Native object list in the data item that changes be sent to subscriber.
Through the above steps, the communication interconnection method being used in Heterogeneous simulation system of the invention is achieved.
