Description

An automatic test device for airborne VHF navigation system receiver

technical field

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

Background technique

With the continuous development of aviation technology, the proportion of airborne electronic systems in civil aviation aircraft is also increasing. According to international standards, airborne electronic systems can be divided into four categories: automatic flight system, communication system, display and recording system, and navigation system. part. Among them, the main task of the navigation system is to guide the aircraft to the designated place safely at the designated time by using an effective method with the prescribed accuracy under the given conditions. At present, the most widely used is radio navigation. The main principle of radio navigation is to use the measurement of radio electrical parameters to calculate the flight parameters of the aircraft.

At present, the basic principle of airborne electronic equipment testing is: when the airborne electronic equipment leaves the factory, the equipment manufacturer will provide the corresponding component maintenance manual (hereinafter referred to as the CMM manual), and the test method and test process will be described in detail in the CMM manual. The testing process and testing standards must strictly follow the CMM manual. The receiver test of the airborne navigation system usually adopts the signal excitation test method, that is, the signal source is used to generate the excitation signal to simulate the navigation signal transmitted by the ground navigation station. Comparing the calculated navigation parameters with the excitation signal generated by the signal source can determine whether the equipment is faulty and the fault range.

At present, the equipment used for airborne electronic system testing is mainly imported, and its price is expensive. Taking the ATEC5/6/7 series with a relatively high market share as an example, to test the airborne VHF navigation system, the cost is more than 7 million yuan. Therefore, instead of relying on imports, there is an urgent need to develop an automatic test device for an airborne VHF navigation system receiver to meet the domestic market demand.
