基于PXI总线的某红外成像导引头便携式测控系统设计

Design of An Infrared Imaging Seeker Portable Measurement and Control System Based on PXI Bus

摘要:

某红外成像导引头在多种试验场合需要对其进行功能和性能测试，现阶段导引头研制过程中配备的测试设备，已逐渐难以满足通用化、轻小型化和高机动性的要求；因此，针对导引头多种试验环境下的测试需求，综合考虑可靠性和经济性等因素，研制了一套基于PXI总线的便携式导引头测控系统，该测控系统具有重量轻、体积小、组装快速等特点，大大提高测试效率；阐述了其系统组成及工作原理，详细介绍了硬件选型及自研LVDS板卡设计、测控系统软件架构设计及测试流程设计；实际应用结果表明：测控系统既满足导引头测试设备测试性、稳定性、可扩展性等总体要求，同时满足转运方便、展开快速、环境适用性等要求。

Abstract:

An infrared imaging seeker needs to be tested for its functionality and performance in a variety of test occasions,at this stage seeker development process equipped with test equipment,it has been gradually difficult to meet the requirements of generalization,miniaturization and high mobility;Therefore,a variety of test environment for the seeker test requirements,comprehensive consideration of reliability and economy and other factors,developed a PXI bus-based portable seeker measurement and control system,the system has the characteristics of light weight,small size,fast assembly and so on,greatly improve the test efficiency;described its system components and working principle,described in detail the hardware selection and self-study LVDS board design,measurement and control system software architecture design and test process design;practical application results show:the measurement and control system not only meets the overall requirements of the seeker test equipment such as testability,stability and scalability,at the same time to meet the transport convenience,fast start,environmental applicability and other requirements。
