摘　　要：针对基于xPC的硬件在环仿真系统,研究了Matlab GUI监控软件的相关开发技术,以解决时钟驱动模式下,数据更新速率慢、显示停顿的问题。在设计监控系统模块化方案的基础上,利用ActiveX控件技术建立虚拟仪表交互界面,提出S函数驱动GUI界面的实时显示方法,实现仿真数据的动态显示。试验台的使用表明,开发的监控系统具有良好的人机交互功能,对仿真数据的采集频率可达100Hz,虚拟仪表的更新速率超过20Hz,数据传输及显示过程耗时小于21毫秒,满足实时监控的要求。Aiming at Xpc-based Hardware-In-the-loop simulation system, some key techniques about monitoring software on the platform of Matlab GUI were investigated, thus solving the problem that the sampling and display of simulation data was relatively slow under timer-driven method. On the basis of modular configuration of monitor system, an interface with virtual instruments was constructed using ActiveX technique, and real-time monitor for simulation process was implemented by utilizing GUI driven by S-function method. A series of HIL simulations show that the developed monitor system has favorable human-machine interface, its sampling frequency reaches 100Hz, the updating frequency of virtual instruments exceeds 20Hz and the data transmitting and displaying delay are less than 21 ms, satisfying the requirements of real-time monitor.
