HLA中的数据收集技术研究

HLA在提高可重用性和互操作性的同时使仿真数据复杂化，增加了仿真系统实现数据收集的难度。该文阐述了HLA影响数据收集的因素及各种数据收集方法的优点与不足，讨论了如何根据仿真目的来确定具体的数据收集方法以及数据收集实现中需要遵守的原则；针对一些仿真系统需要对邦员及模型内部数据进行收集的要求，在嵌入代码收集方法的基础上提出了分层对象数据收集方法，并给出了这一方法在水声对抗仿真系统中的应用。

Study on Data Collection Technology in HLA

With the improvement of the reusability and inter-operability in HLA,the simulation data became complicated,which made the realization of data collection difficult for simulation system.Thus,factors that affect data collection in HLA,the advantages and shortcomings of each data collection method were listed firstly.Secondly,the problem of how to implement data collection according to the simulation purpose was discussed as well as the principles obeyed in data collection's realization.Finally,the Layered Object-Oriented Data Collection Method(LOOM),which aims to meet the requirements of collecting private data in federates/models for some simulation systems,was proposed based on the embedded code method,and the realization of LOOM in the acoustic confrontation simulation system was given.
