摘　　要：为了解决"铁鸟"试验台飞机仿真试验中多系统间的数据共享问题,使数据在传输过程中具有更强的实时性、高效性和异常诊断性,提出了一种反射内存网实时数据传输协议,搭建了基于反射内存网的网络结构,描述了反射内存卡中断方式传输数据的缺陷,介绍了多系统内存分布和数据传输协议。理论分析和试验结果均表明,本协议能够满足"铁鸟"试验台飞机仿真试验中多系统间实时数据传输需求,同时能够快速诊断各系统异常情况,提高了在仿真试验中飞机飞行的真实性和逼真度。In order to solve the problem of the data sharing in aircraft simulation test system of ＂iron bird＂ test-bed, more realtime, efficient and abnormity diagnosis in the transmission process. A kind of real-time data transmission protocol based on reflective memory network is proposed, the network structure is built, and the defects of interrupt mode in reflective memory card itself are described, memory allocation and data transmission protocol are introduced. Theoretical analysis and test results show that this protocol can meet the real-time requirements of data transmission between multi-systems of ＂iron bird＂ test-bed,and can quickly diagnose the abnormal situation of the system. The authenticity and fidelity of the aircraft flying in the simulation test were improved.
