The invention discloses a comprehensive test system for an aircraft electronic instrument, and relates to the technical field of aircraft instrument testing, the comprehensive test system comprises a swing rotary table, a to-be-tested piece is fixed on the swing rotary table through a preset tool, and a static pressure output air pipe and a dynamic pressure output air pipe of an atmosphere data tester are both connected to an air inlet of the to-be-tested piece; the test board is electrically connected with the to-be-tested piece, and the test board tests the to-be-tested piece by adopting a preset program. According to the invention, discrete magnitude control, working power supply control and ARINC 429 input/output control are provided through the testboard, flight attitude simulation is provided through the swing turntable, flight parameters of height, airspeed and Mach number are provided through the atmosphere data tester, and a scheme that foreign special automatic test equipment is matched with automatic test software for testing can be replaced; the whole structure is very simple, related electronic devices are all common electronic components, the manufacturing and maintenance cost is very low, and compared with the prior art, the cost is greatly reduced.

    本发明公开了一种用于飞机电子仪表的综合测试系统,涉及飞机仪表测试技术领域,包括摇摆转台,待测试件通过预设工装固定在摇摆转台上,大气数据测试仪的静压输出气管和动压输出气管均连接到待测试件的进气口,测试台通过与待测试件电连接,测试台采用预设程序对待测试件进行测试。本发明通过测试台提供离散量控制、工作电源控制及ARINC 429输入/输出控制,通过摇摆转台提供飞行姿态模拟,通过大气数据测试仪提供高度、空速及马赫数飞行参数,能替代国外专用自动测试设备搭配自动测试软件进行测试的方案;整体结构非常简单且所涉及的电子器件均为普通的电子元器件,其制作及维护成本十分低廉,较现有技术相比,成本有很大幅度的降低。
