Research On The Air Force Battle Simulation System Of Distribution

Research on the distributed system has been carried out for a long time. To deal with the interoperability problem for the system, middleware was used. In the early-day's work, researchers focused on solving the problems of interoperability among heterogeneous platforms and environments, and seldom took account of attributes of real-time, dependability and others. In a word, the functions of distributed system were emphasized and its performance was ignored. With the development of the computer and the communication technology, the network bandwidth is expanded and the CPU speed is increased, and then people turn their attention to the performance of the distributed system which includes real-time, fault-tolerance, dynamic adaptability and combined real-time and fault-tolerance, etc. In this paper, distributed combat simulation study to investigate and verify the basic technology, Consists mainly of middleware, runtime support environment, time management, data distribution management technology research. Finally, the implementation of the model used in the test results of these technologies. The main contents include(1) Distributed simulation architecture based on standards, shows the naval air combat simulator modeling the object of each module design.(2) Combat Simulation System based on the messages between the modules communicate with each other more frequently and security of the characteristics, selected Common Object Request Broker Architecture technology as a means of transmission packets, and the Common Object Request Broker Architecture technology to verify the mechanism.(3) During simulation in order to limit and control the amount of information and exchange of data management techniques used in data distribution(4) In order to ensure the logical consistency of the incident time and runtime support environment with time management(5) From the scientific and practical and user-friendly point of view of software architecture built simulator, simulator design to a reasonable framework. When generating new demand, you can follow up on this basis function expansion, does not involve major structural adjustments to ensure a greater degree of compatibility may be extended downward. At the same time using the software interface is also user-friendly highlights...
