摘　　要：为了迅速地搭建船舶避碰仿真平台,采用了HLA的模块化建模思想,既能充分利用现有的功能代码,又能不断添加新的功能模块,省时而高效地完成了仿真任务.首先阐述了基于HLA的船舶避碰仿真平台开发的软硬件环境及平台的体系结构,然后充分把整个船舶避碰仿真平台作为一个联邦,将其按功能划分成若干个联邦成员,按照美国国防部提出的联邦开发的过程——FEDEP进行分布式仿真的设计和开发.想定联邦剧情、划分联邦成员功能、设计FOM/SOM文件,最终用VC2003.net进行各联邦成员的程序开发,建立起了基于HLA的两船避碰仿真平台.在想定剧情下的避碰仿真试验结果表明,该平台能够很好地实现船舶避碰的功能,同时,该分布式避碰仿真平台比集中式仿真具有更好的灵活性和可扩充性,便于未来向复杂的多功能避碰平台的演化和升级.In developing a ship collision avoidance simulation platform, modularized modeling through a high level architecture （HLA） completes the simulation task quickly and effectively. This allowes full use of existing functional code modules, and allows the addition of new functional modules at any time. The hardware and software development environments needed for a ship collision avoidance simulation platform were proposed, then the whole colli- sion avoidance simulation system was considered as a federation divided into several relatively independent federate units in accordance with their corresponding functions. The design and development of distributed simulations were undertaken according to the federation development and execute process model （FEDEP） suggested by the US Department of Defense. The federation scenario was conceived, the functions of federates were plotted and the federation object model （FOM） and simulation object model （SOM） were devised. Finally, program development was executed for all federates with VC2003. net and the ship collision avoidance simulation platform was constructed. Simulation results show that the platform can fulfill its collision avoidance function well. Moreover, compared with a centralized simulation platform, the distributed collision avoidance simulation platform is easy to evolve and upgrade to a more complicated multifunctional collision avoidance systems.
