基于虚拟仪器的某制导系统总控单元研制

Implementation of the control unit in missile control and guidance system based on Labview

本文给出了基于PXI总线平台和LabWindows/CVI软件开发环境的制导控制系统总控单元的软硬件设计,重点讨论了如何使用LabWindows/CVI软件平台实现对第三方板卡驱动函数的调用以及采用LabWindows/CVI的双核CPU、多线程机制实现对多路电源的实时监控。测试结果表明,该系统设计合理,使用方便,完全满足用户的技术要求。

The hardware and software design of the control unit in missile control and guidance system is introduced based on PXl bus and LabWindows/CVI. This paper discussed how to call the driving function provided by the third party and use the multi-thread method to realize the real-time monitor of multiple power supply in the LabWindows/CVI software environment. The result of the test indicates that the system ,which is rational, convenient and efficient, takes full advantage of multi-thread technology and can satisfied the customer＇ s request completely.
