Abstract

The invention discloses a multiple-rotor-wing unmanned aerial vehicle sensing and avoiding system which comprises a barrier avoiding module. The output end of the barrier avoiding module is connected with a flight control module, the input end of the barrier avoiding module is further connected with a navigation module, the barrier avoiding module is further connected with an ADS-B perception module for data receiving and sending, the ADS-B perception module comprises an ADS-B OUT transmitting module and an ADS-B IN receiving module, the ADS-B OUT transmitting module is connected with a transmitting antenna, and the ADS-B IN receiving module is connected with a receiving antenna. The invention further discloses an avoiding method which simplifies spatial perception and barrier avoiding complexity of an unmanned aerial vehicle, can guarantee safe space flight of the unmanned aerial vehicle without dependence on an air control system, and is suitable for the low-flying multiple-rotor-wing unmanned aerial vehicle sensing and avoiding system.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle navigation and control, and in particular relates to a multi-rotor unmanned aerial vehicle perception and avoidance system and an avoidance method thereof. Background technique [0002] With the continuous development of UAV technology in the civilian field and the continuous implementation of the low-altitude field open policy in recent years, a large number of applications of multi-rotor UAVs in the low-altitude civilian field will become inevitable. A large number of unmanned applications in the low-altitude field will inevitably bring new threats to flight safety and traffic control in the airspace. [0003] In the existing UAV space perception technology, commonly used airborne sensors include photoelectric, radar and so on. Information is acquired through sensors, and target status information is extracted according to the back-end processing of sensor information, so as to ...
