The Research And Implementation Of New Simulation System Of Data Link Communications System

Data link system is a communication network as a link connecting the digitized battlefield command center,an informational processing combat troops,and weapons platforms,integrated information processing system of exchange and distribution.Since the data link enables the entire operational system for full-dimensional perception,real-time information transmission and information processing capabilities,to provide information to support the integration of joint operations,so it is the multiplier for information,intelligence and integration of military combat in the future.Based on Link11 data link,in order to improve the system data link system and reduce the cost of hardware,this paper studies a new design based on a multi-core multi-threaded.Through the use of modern multi-core processor hardware design of the structure,we can improve the work performance of the system,with the use of multi-threading method of analog alternate functions of the original link terminal link system by implementation of multiple MCU.To achieve the above goals,this paper first uses VMware virtual organization working to build a dual-core Linux platform.On top of this technology,mainly to study the scheduling of operations multi-core processors,analyzed and compared the differences between single and multi-core design.On this basis to achieve full use of multi-core processor performance goals;and analysis of the communications between multiple threads,synchronization mechanisms and multi-threaded tasks assigned when the load balancing problem.After study of the multi-threaded,multi-threaded design a reasonable solution.Finally,in order to present the communication process of the new design,and to explore the important performance TFT screen indicators include refresh rate,and to design the display interface of the communication display platform.In order to achieve the goal of a plurality of terminal links in conventional simulation system Link11 data communication system,using a large number of MCU to implement the corresponding terminal function.Not only the hardware overhead is relatively large and the transmission performance of the system is not high.The new design scheme can solve the above problems.The results of this paper verify the feasibility of the new design.
