The Real-time Quality Realization of Hardware-in-the-loop Simulation of Laser Guided Weapon

半实物仿真中的实时性需要多方面保证。该文对激光制导武器半实物仿真系统中与实时性相关的方面进行了探讨,采用实时仿真计算机和实时通讯网络设计系统,对WindowsNT操作系统的实时性以及通过串行口的实时控制进行了讨论。对全系统单步运行时间进行了试验和定性分析。试验结果表明,采取这些措施能较好地满足半实物仿真系统的实时性要求。

The Real-time quality of Hardware-in-the-loop(HWIL) simulation needs multi aspects consideration. This paper discusses these facets which relate with real-time quality of HWIL simulation of laser-guided weapon. The real-time simulation computer and real-time communication network are adopted to design the system. The real-time quality of Windows NT OS and real-time control through serial communication are studied. The runtime of single step is tested for the whole system and qualitative analysis is carried out. The results show that the system can fulfil the requirements of real-time quality when these methods are adopted.
