一种数字图像板测试系统的设计与实现

摘要

为了完成对某型号空空导弹中的数字图像板的测试，本文提出了以PCI总线测试计算机为核心的自动测试系统，并完成了软硬件设计。该系统的硬件主要包括PCI总线测试计算机、多块PCI总线接口板卡、基于DSP的通信转接卡、信号发生器、电源调理板卡以及被测图像板。该系统软件部分以Windows XP为开发平台，采用模块化设计思想，实现了图像板各项功能的测试和结果显示。实际的应用表明：该系统具有功能齐全、数据安全可靠、操作方便、人机界面友好等特点，满足了用户需求。%In order to accomplish detection of the digital image board in a certain type of air-sto-air missile, this paper proposes a test system where PCI bus test computer plays a central and completes the design of the system's software and hardware. The hardware of the system is composed of PCI bus test computer, PCI bus interface boards, communication swich card based on DSP, signal generator, Power Control board and the digital image board under test. The software part of the system which uses Windows XP as a development platform and adopts modular design method is able to accomplish the tests of the digital image board and show the results. The practical application indicates that this system holds many characteristics such as complete function, convenient operation, friendly manmachine interface, and data security and reliability, which satisfy the users' needs.
