Realization of Integration Technology of Ship Collision Avoidance System based on HLA

Integration technology is an exciting emerging area with good prospect. As a common distributed interactive simulation standard, High Level Architecture (HLA) mainly emphasizes on the reusability and interoperability of different simulation components. So it can be successfully applied in integration area. Any existing simulation program with special function can be integrated into distributed simulation system based on HLA, and then become reusable unit in HLA federation development. This paper takes a ship collision avoidance simulation system as an example to present the integration method by HLA. Simulation scenario, federation object model (FOM) and simulation object model (SOM) are established according to available system function modular structure. Finally, a ship collision avoidance simulation system based on HLA is established on the software development platform of VC2003.net.The collision avoidance simulation results validate the integration method based on HLA. Moreover, the developed system is good at flexibility and expandability and easy to evolve and upgrade to more complex multi-functional collision avoidance simulation integration system.
