摘　　要：面向航空飞行器的半实物分布式仿真系统中,传统的基于Socket的编程方法难以满足网络通信的多样性、实时性及高可靠性等要求。通过分析仿真系统的通信特点,基于TAO(The ACE Orb)实时中间件,利用其提供的抽象机制、命名服务和调度服务等,提出了针对控制通信与仿真通信的网络通信模型。实验结果表明,这一模型额外开销较小,可以满足目标系统的技术要求。基于TAO中间件实现仿真平台网络通信,有效降低了网络通信的设计复杂度,保证了实时、高效、可靠的网络通信。Hardware-in-the-loop distributed simulation platform requires diverse network communication services,real-time characteristics and high reliability,but the traditional socket based programming method can not meet these requirements.In this paper,the characteristics of the communication was analyzed,a network communication models based on the real-time middleware TAO(The ACE Orb) was proposed through using Abstraction mechanisms,naming service,scheduling service and so on.The experimental results indicate that the overhead of this communication model is low and can meet the technical requirements of distributed simulation platform.The network communication method based on TAO can simplify the software design complexity and provide a real-time,efficient and reliable network communication service.
