导弹系统的双机并行实时仿真研究

Study on Dual Parallel Real-time Simulation of Missile System

由于高级语言编写的软件在可读性、可移植性和通用性等方面的优点 ,在微机应用日益普遍的情况下 ,利用广为科技工作者使用的 FORTRAN语言在微机上实现弹道实时仿真具有重要的意义。但是用高级语言在微机上进行实时仿真 ,需要解决运算速度和同步问题。如果仿真结果要用图形实时在线显示 ,软件就要在图形方式下运行 ,其速度比在字符方式下慢得多。本文研究了利用微机打印口使两台微机联系起来进行并行处理的技术 ,不仅实现了某反坦克导弹飞行弹道的实时仿真 ,并且将人工识别、捕获目标的外部操作过程引入了实时仿真中 ,使仿真结果更具有实际意义。

Since software written in high level languages has stronger readability, transportability and versatility, it is significant to use FORTRAN for real time trajectory simulation on microcomputers. To do this, there are two problems i.e. operation rate and synchronization need to be resolved. When simulation data are shown on linely in graph, the software will run in graphic mode and the operation rate will be slower than that in text mode. A method of dual parallel simulation through LPTs of two microcomputers is studied. A real time trajectory simulation of an anti tank missile is realized and some external operations such as target identification and acquisition are introduced into simulation. This makes the results of simulation more significant.
