Abstract

The embodiment of the present application discloses an avionics test system. The device comprises a tested device, a test platform, and a signal transmission channel control device. The signal transmission channel control device is connected with the tested device through a tested device interface and is connected with the test platform through a test platform interface, the signal transmission channel control device comprises at least two wiring matrix boards, a resource connector, and a signal transmission channel control unit, wherein the wiring matrix board is provided with a loopback connector for connecting the at least two wiring matrix boards, the resource connector is connected with the test platform interface; the wiring matrix board is connected with the tested device interfacethrough a ribbon cable, the signal transmission channel control unit is used for controlling a signal transmission channel; and the test platform is used for providing test resources to implement functional test of the tested device. By adopting the above technical scheme, the signal transmission channel can be flexibly controlled, meanwhile, as the control operation is simple, low-level errors such as operation errors and the like can be prevented from influencing the accuracy of the test result.

Description

Technical field [0001] The embodiments of the application relate to the technical field of avionics testing, and in particular to an avionics testing system. Background technique [0002] Airborne avionics equipment mainly includes communication, navigation, display, cockpit entertainment and other equipment. It completes aircraft and ground communication, navigation, information processing and control. It is the core and most important equipment of the aircraft and directly affects the advanced level and comprehensive capabilities of the aircraft. . The airborne avionics equipment is composed of multiple functional units, and there are many problems to be tested, the test process is complicated, and the test is difficult. There are hundreds of test channels and hundreds or even thousands of test ports. The test channels are complex, with multiple channels and multiple interfaces, making flexible control difficult. [0003] In the traditional test scheme, there are mainly two sol...
