Abstract

The invention belongs to the technical field of circuit board testing, and particularly relates to an aircraft communication navigation system integration test device which comprises a distributed hardware layer, a real-time test software layer and a data interaction and control layer. The distributed hardware layer comprises a test bed, and a test assembly, a marking assembly, a circuit board centering and positioning assembly, a marking and isolating assembly and a corner-sleeving type reinforcing assembly which are integrated on the test bed. According to the invention, the marking assembly is utilized, when a fault point is detected, the point is automatically marked through the marking pen, and when a subsequent operator repairs the circuit board, the fault point can be accurately found only by observing the marked position, so that the improvement of the repair efficiency is facilitated.
