Communication navigation identification system module test platform

Abstract

The communication navigation identification system module test platform disclosed by the invention is high in execution efficiency, easy in case editing operation and extensible in software and hardware. According to the technical scheme, a test host carries out real-time signal processing and control based on an FPGA, general test instrument equipment is modularly integrated into a test host box body, scheduling of test tasks is organized and managed according to excitation signals provided by an excitation unit, and the test efficiency is improved. On-line debugging and signal detection are monitored in real time by receiving and transmitting communication data, adaptive switching of a switch matrix, automatic acquisition and recording of performance index test data of a tested module and synchronous control are realized, a communication environment of data interaction of various types of buses of the tested module in an airborne system is simulated, and automatic test of performance is realized; by collecting test data of the test instrument assembly, a test report analysis model and a test result data management center are established, a test report is automatically generated, and different test resources and test conclusions are output.

Description

technical field

[0001] The invention relates to the field of test and measurement, and is a module test platform mainly used in an avionics communication navigation identification system (CNI). Background technique

[0002] With the rapid development of avionics and computer technology, the degree of integration of avionics systems is increasing day by day, and higher requirements are put forward for system testing. Among them, the research of communication navigation identification system is very important. However, there are currently a series of problems in the airborne communication, navigation, and identification functions. As an important part of the aircraft avionics system, the communication navigation identification system is particularly important for the integrity test of the module function and the quality test of the performance index. But in the airborne equipment test, the test of communication navigation identification equipment is the most complicated. In...
