Light beam generation device and method for generating visible boundary and electronic boundary system

Abstract

The invention mainly provides a light beam generating device for generating a visible boundary, an electronic boundary system and a method, and belongs to the field of unmanned aerial vehicles. The device includes: at least one light source device, which is arranged on the electronic boundary device, wherein the electronic boundary device is used to set the flight area of ​​the UAV, and the electronic boundary device is set independently of the UAV, and The flight area of ​​the unmanned aerial vehicle is determined based on the position information of the electronic boundary device; the light source device emits a visible light beam for prompting the range of the flight area. By adopting the above solution, the visible boundary of the flight area of ​​the UAV can be formed, which facilitates the onlookers to clearly know the scope of the flight area, and improves the flight safety of the UAV.

Description

Technical field: [0001] The invention mainly relates to the field of unmanned aerial vehicles, and in particular to a beam generating device, an electronic boundary system and a method for generating a visible boundary. Background technique: [0002] Unmanned aircraft, referred to as unmanned aerial vehicle (UAV), is a new concept of flying equipment in rapid development. Etc. Unmanned aerial vehicles are equipped with multiple types of sensors, which can realize real-time image transmission, detection of high-risk areas, etc., and at present, the scope of use of unmanned aerial vehicles has been expanded to three major fields: military, scientific research, and civilian use, and has a wide range of applications. [0003] However, although the existing unmanned aerial vehicle can achieve long-term and long-distance target detection or target tracking operations, but because its flight area may not have been set in detail, the unmanned aerial vehicle may exist during flight....

AI Technical Summary

Problems solved by technology

However, in the above technical solution, when the UAV is far away from the ground control system, the signal is too weak, or when the signal transmission between the UAV and the ground control system is interfered, it is easy for the UAV positioning information to fail to be timely. If it is transmitted to the ground control system so that the above-mentioned boundary monitoring function cannot be completed, then the UAV will exceed the preset safety range and lose contact with the ground control system.

[0005] Therefore, based on the above-mentioned technical problems, the applicant has proposed an electronic boundary device to flexibly set boundaries for the flight activities of unmanned aerial vehicles, thereby conveniently establishing a no-fly area (protected area) or a site that allows flight On the basis of this patent application, the applicant found that there is still a technical problem: although there is an electronic boundary physically, this electronic boundary is completely based on wireless signals and is invisible

For example, there may be people who do not know the existence of the electronic border, thus intruding into the flying field originally designed for the activities of unmanned aerial vehicles, resulting in potential risks and threats
