Description
Technical field
The present invention relates to network communication field, specially a kind of flight simulator network communication side based on dynamic socket
Method belongs to network data communication technical field.
Background technique
In flight simulator equipment composition it is numerous, needed between each system carry out data communication, how efficiently, uniformly into
Row communication is very crucial.Generally, flight simulator uses Ethernet building network system, is handed between each subsystem by network
Data are changed, using UDP is point-to-point and multicast mode, the period sends and barrage reception mode.When two computers are logical by multicast
When news, unified multicast section, multicast port number need to be added, and communication interface needs unification；When two computers are led to by point-to-point
When news, receiving end, transmitting terminal, and unified communication interface need to be bound.Both communication modes are disadvantageous in that: communication side
Formula is many and diverse, and communication channel is more, data-interface disunity, therefore causes flight simulator maintenance workload big, and working efficiency is low.Together
When, it, will when one of system needs to increase the data volume of communication since the degree of coupling of each component computer of simulator is high
Cause associated all communication branches to increase identical data-interface, increases simulator workload, be not easy to later period system tune
Examination, maintenance.
Summary of the invention
For above-mentioned actual conditions, technical problem solved by the invention is to provide a kind of flight mould based on dynamic socket
Quasi- device network communication method, to solve, communication channel in original communication means is more, data-interface disunity bring flight simulation
Device maintenance workload is big, ineffective problem.
In order to solve the above technical problems, a kind of flight simulator network communication side based on dynamic socket proposed by the present invention
Method, this method are established under conditions of each system of flight simulator is connected using Ethernet, and specific method step is:
S1: dynamic socket configuration.By interface configuration tool, each computer configures two dynamic socket configuration files, packet
It includes and receives data configuration file and transmission data configuration file.
S2: data communication network configuration.Communication network configuration file is defined, multicast reception identification feature information RI is distinguished
Flight simulation computer network reception configuration file is written, other each subsystem computer networks are sent in configuration files；By group
It broadcasts and identification feature information SI is sent to be respectively written into flight simulation computer network transmission configuration file, other each subsystem computers
Network receives in configuration file.
S3: flight simulation computer dynamic interface data receives.Other each subsystem computers will respectively send configuration text
Corresponding dynamic socket data are sent in Ethernet in part.Flight simulation computer passes through each data of same multicast reception
Packet parses each frame data in data packet, corresponding data entry is selected in configuration file, and map to corresponding parameter.
S4: flight simulation computer dynamic interface data is sent.Flight simulation computer, which will be sent in configuration file, to be owned
Dynamic socket data are to Ethernet.Each subsystem computer parses each frame in data packet by same multicast reception data packet
Data select corresponding data entry in respective data receiver configuration file, and map to corresponding parameter.
S5: repeating the process of S3 to S4, until network communication terminates.
In above method step, it is preferable that the dynamic socket configuration file in S1 step is with " one entry of variable "
Data are written in fixed format, and file is with the generation of TXT format.
Further, the fixed format of above-mentioned data are as follows: chief editor ID, sub- number SUBID, data type TYPE, unit
UNIT, title NAME, wherein using ID and SUBID combination as the unique identification of each dynamic data interface.To in S3 and S4
It, can be by selecting the data strip of corresponding ID and SUBID in configuration file when parsing each frame data in data packet in step
Mesh, and map to corresponding parameter.
Preferably, the multicast reception identification feature information RI in S2 is multicast reception address xxx.x.x.xxx and port
Xxxx, it is that multicast sends address yyy.y.y.yyy and port yyyy that multicast, which sends identification feature information SI,.
The above-mentioned flight simulator network dynamic means of communication, communication modes are simple, communication interface is unified.It is each to need to carry out
The interface of communication is standardized in the same way, transmitting terminal by all data pass through in one format multicast mode be sent to
Too net, receiving end receive all data, and each system according to dynamic socket configuration file, simultaneously locate by data entry required for selecting
Reason, the data of configuration file are conducive to increase, modify interface, be conducive to system with the text files memory of unified format
Maintenance, the guarantee of simulator.
