A No-Fly Zone Recognition and Navigation System with Arbitrary Graphics for Unmanned Aerial Vehicles

Abstract

The invention discloses an identification and navigation system of a random-pattern no-fly zone of an unmanned aerial vehicle. The identification and navigation system is composed of an unmanned aerial vehicle positioning navigation module, a flight control center module, a dispatching center module, an intermediate interface module, a monitoring module, a WebService module and an Oracle databasemodule. The unmanned aerial vehicle positioning navigation module is responsible for generating a random-pattern no-fly zone, setting a warning region, determining whether an unmanned aerial vehicle enters the warning region, and performing a border-crossing trend determination and no-fly flight path planning algorithm when the unmanned aerial vehicle approaches the no-fly zone. The flight controlcenter module is responsible for data parsing and storage. The dispatching center module is responsible for data routing. The intermediate interface module serves as data transmission middleware. Themonitoring module is responsible for real-time monitoring and scheduling of an unmanned aerial vehicle. The WebService module is used for realizing cross-platform service invoking. The Oracle database module is responsible for storing information of an unmanned aerial vehicle and a user. According to the invention, a random-pattern no-fly zone can be set for an unmanned aerial vehicle; and warning is carried out when the unmanned aerial vehicle enters the warning region and a scheduling algorithm is performed to enable the unmanned aerial vehicle to return to a safety zone, so that a problemthat the unmanned aerial vehicle enters the no-fly zone without authorization is solved.

Description

technical field [0001] The invention relates to a no-fly zone recognition and navigation system of an arbitrary pattern of an unmanned aerial vehicle. Background technique [0002] UAVs were originally used in the military field, such as battlefield reconnaissance, damage assessment, etc.; as more and more companies began to adopt UAV technology, UAV manufacturers that originally belonged to the military field also began to provide Services to meet the needs of the commercial market for drone technology, such as weather detection, air traffic control, etc. Due to the advantages of low cost, environmental protection and energy saving, strong concealment, and no casualties, more and more drones have been put into civilian use. However, with the popularity of drones, many safety issues have also been triggered: for example Recently, there have been frequent "black flying" incidents of drones. Drones randomly occupy sensitive public areas, causing flights to be unable to land o...

Problems solved by technology

[0017] The above UAV no-fly zone monitoring system cannot be applied to any graphic no-fly zone, the algorithm complexity is high, the hardware deployment is difficult, the compatibility is poor, it does not support multi-user, multi-UAV remote supervision scenarios, and the supervision effect is poor. Problem, the present invention provides an arbitrary graphic no-fly zone identification and navigation system for drones. The invention can set arbitrary graphic no-fly zones for unmanned aerial vehicles, solve the problems of difficult hardware deployment and poor compatibility, and use the horizontal ray intersection method to judge no-fly zones. Whether the man-machine enters the warning area or not, the algorithm complexity is low. When the drone approaches the no-fly zone, it will issue an alarm and execute the scheduling algorithm to return to the safe area. Illegal flights in no-fly zones
