| Marine engineering operation safety simulation system is the first large-scale complex operation simulation system in the domestic,it is built for the fields of marine engineering design,construction,installation,underwater operation and emergency maintenance operation,aiming at previewing assessment of the operation plan and land training of operation personnel,and pilelay vessel handling simulation is a subsystem of it.In this paper,it was studied the development and implementation of large complex distributed simulation system basing on HLA(High Level Architecture).At first,this article begins with the concept and basic principle of HLA,the author has carried on the analysis and research of HLA,studied the federal development process of simulation system by the FEDEP,at the same time for large scale system was faced with the problem of the spatial and temporal consistency,this article has studied the spatial consistency and temporal consistency,and put forward the spatial and temporal consistency control model based on HLA/RTI.Secondly,it has designed the marine engineering operation safety simulation system under HLA technical framework.In the following section,it has confirmed the system functional requirement and the system composition,classified and determined the federate and its function based on the system requirements,then,the system architecture based on HLA and the system network structure based on RTI had been designed.At last,this article has used the pilelay vessel handling simulation subsystem in the system as an example,conceived federal plot,designed the federation,determined the publish and subscribe agreement according to the data exchange information between the federates,designed the FED based on the model of FOM/SOM development,completed the spatial and temporal consistency control interface encapsulation based on HLA/RTI and SOM program,ending with the realizing of the pilelay vessel handling simulation system based on HLA. |
