Distributed drone measurement and control data link comprehensive test system and method

Abstract

The distributed UAV measurement and control data link comprehensive test system is aimed at testing the technical performance indicators of UAV measurement and control data link equipment. The UAV measurement and control data link equipment is divided into two parts: the ground data terminal and the airborne data terminal. The comprehensive test system has designed two cabinets, which are respectively placed near the ground data terminal and the airborne data terminal. The test needs to be carried out in a typical electromagnetic environment Under the test, the electromagnetic environment interference simulation simulation cabinet (referred to as the anti-interference cabinet) was designed and placed near the airborne data terminal to transmit interference signals to test the anti-interference performance of the UAV measurement and control data link equipment. The distributed UAV measurement and control data link comprehensive test system includes the main test cabinet connected to the ground station, the sub-main test cabinet connected to the UAV, the anti-jamming cabinet, multi-path reflectors, antennas, interconnected optical cables and supporting equipment.

Description

technical field [0001] The invention relates to the field of automatic testing of unmanned aerial vehicle measurement and control data links. A distributed automatic test system is used to construct a comprehensive test system for testing the technical performance of unmanned aerial vehicle measurement and control data link equipment under typical working conditions and electromagnetic environments. Background technique [0002] In recent years, the safety detection of drones has been paid more and more attention, and it has become an urgent problem to be solved. The main reason is that with the gradual opening of the flying airspace, a large number of drones will be used in various fields. The safety of the UAV system is not only related to itself, but also to the safety of other aircraft in the same airspace, as well as the safety of people's lives and property in the UAV flight area. At present, my country does not have a set of standards and regulations on the safety te...

AI Technical Summary

Problems solved by technology

[0004] At present, the safety and usability of the UAV measurement and control data link can only be verified by long-term flight tests, which is time-consuming and costly

Moreover, the flight test can only be carried out in a few typical working conditions and environments, and it is difficult to cover all conditions.

When the UAV needs to perform tasks in a new environment, it can only do flight verification again, otherwise it will face huge risks
