Description

Automatic testing device for receiver of airborne very high frequency navigation system

Technical Field

The invention relates to a test technology of airborne electronic equipment, in particular to an automatic test device of an airborne VHF navigation system receiver, which is used for automatically testing the airborne VHF navigation system receiver and can also be used for civil aviation maintenance and engineering teaching.

Background

With the continuous development of aviation technology, the proportion of airborne electronic systems on civil aircrafts is increased continuously, and according to international standards, airborne electronic systems can be divided into four parts, namely an automatic flight system, a communication system, a display and recording system and a navigation system. The main task of a navigation system is to guide an aircraft safely to a specified location at a specified time and with a specified accuracy in an efficient manner under defined conditions. The most widely used at present is radio navigation, the main principle of which is to use the measurement of radio electrical parameters to calculate flight parameters of an aircraft.

The basic principle of the current airborne electronic equipment test is as follows: when the onboard electronic device is shipped from the factory, the device manufacturer will provide a corresponding parts maintenance manual (hereinafter CMM manual) in which the test methods and test procedures will be described in detail, all of which must strictly comply with the CMM manual. The airborne navigation system receiver test usually adopts a signal excitation test method, namely, a signal source is used for generating an excitation signal to simulate a navigation signal transmitted by a ground navigation platform, equipment to be tested receives the excitation signal and then resolves the excitation signal into corresponding navigation parameters, and the resolved navigation parameters are compared with the excitation signal generated by the signal source to judge whether the equipment is in fault or not and judge the fault range.

At present, equipment for testing an airborne electronic system mainly depends on import, the selling price of the equipment is expensive, and the cost is more than 700 ten thousand yuan for testing the airborne VHF navigation system by taking the ATEC5/6/7 series with higher market share as an example.
