Design And Implementation Of Multi-Business Message Distributation System In Data Link Simulation

With the development of military technology,various kinds of military equipments are emerged.And in the battlefield of rapid change and rapid warfare,the message delivery efficiency directly influences the outcome of the campaign.So how to quickly process large amounts of data and adapt to a variety of message type command systems are critical.And There is no possibility to test the case in the real envirement.This paper studies and designs a kind of multi-channel real-time simulation system.The user interface using the python qt development which can run on multiple platforms.Optimizes each link,finally makes the DSP access link message delay less than 2 ms and the link access delay is less than 7.8125 ms.The biggest support is 400 simulated users.The content of this article is as follows:The network model adopts time-division multisite protocol,and analyzes the synchronization protocol,time gap distribution algorithm and multi-network structure,and finally determines the design realization of the network plan.Terminal model using Link 16 protocol and analyzes Link 16 message format.Then design a simulated news message format.Analyzes the Python language and C language structure differences.Using specific process of python struct module to process the message.Describe the data link simulation system controller and the design of communication protocol,especially the interface of the DSP controller and simulator design.Explain the design of this system and the user interface.Including Link 16 main menu view,connection login view,system configuration view,loading network plan view,message receiving view,as well as in client development.Solve the problem child thread to update the message in main UI thread rightly.Considering the performance of the system,the multi-thread and multi-process are compared,and finally the multi-process is applied to improve the operation efficiency of the program.Finally,the simulation system is introduced,and the simulation results are analyzed and the preplan design is optimized.
