摘　　要：针对半实物仿真中大数据量数据的实时通信要求,提出一种xPC系统下利用并口中断的并行数据通信方法,解决了xPC系统下利用并口中断实现并行数据通信、硬件中断获取与应用,以及软件实现等关键问题。利用该方法设计了某型三轴转台的数据通信模块,可实现三轴转台三路角位置信号的正确发送和接收。试验证明了该方法的有效性,提高了xPC目标的应用扩展。To satisfy the requirement of large amount of real-time data transmission in hardware-in-loop simula- tion, the parallel transmission technology using the parallel port interrupt is proposed. Some key technologies based on xPC target are studied, such as parallel transmission using parallel port interrupt, acquisition and ap- plication of hardware interrupts, and software realization. The communication module using this method is tested on the three axis simulator, which can send and receive the angle information of the simulator correctly. Tests prove that the proposed method is effective and can help the expansion of the xPC target.
