基于HLA的半实物仿真时间管理策略的研究和实现

Research and Implementation of the Time Management in the Semi-Physical Simulation Based on HLA

在基于HLA的半实物仿真系统中,时间管理策略的设置是保证两种不同机制系统能够进行正确时间推进的有效方法。综合介绍HLA接口规范中的时间管理的主要内容,分析HLA接口设备对时间管理的要求,给出可以采取的时间策略,并根据这一分析结果,设计了一套测试时间管理策略的实验验证方案。实验结果表明,HLA接口设备采用基于时间控制不受限时间管理策略最为可行。同时,为了提高传输性能,建议采用分时法进行数据传输,当确实有大量数据需要一次发送时建议采用多个小包组合成一个大包的方法进行传输。

In the semi-physical simulation system based on the HLA,the setting of time management services is an effective way to make the two systems to advance correctly.The paper introduces the main content of time management services of HLA Interface rule,then analyzes the impact of time management to the High Level Architecture(HLA) interface devices and offers an adop table time management choice,finally designs an approach to test the real time performances according to analysis outcome in the front.The experiment result shows that time-regulating but not time-constrained is the best choice to the HLA Interface Devices.Simultaneity,time sharing transmission can improve the real-time performances in the HLA semi-physical simulation system.
