Distributed comprehensive test system and method for unmanned aerial vehicle measurement and control data chain

Abstract

A distributed comprehensive test system for an unmanned aerial vehicle measurement and control data chain is used for testing technical performance indexes of unmanned aerial vehicle measurement and control data chain equipment. The unmanned aerial vehicle measurement and control data chain equipment is divided into two parts: a ground data terminal and an onboard data terminal; the comprehensive test system is designed with two cabinets placed nearby the ground data terminal and the onboard data terminal respectively; the test is implemented in an electromagnetic environment of a typical working condition, so the system is designed with an electromagnetic environment interference simulation cabinet (anti-interference cabinet for short) placed nearby the onboard data terminal to emit interference signals, thus testing the anti-interference performance of the unmanned aerial vehicle measurement and control data chain equipment. The distributed comprehensive test system for the unmanned aerial vehicle measurement and control data chain comprises a main test cabinet connected with a ground station, a secondary test cabinet connected with an unmanned aerial vehicle, the anti-interference cabinet, a multi-path reflection plate, an antenna, interconnecting optical cables, supporting equipment and the like.

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
