Anti-collision method and device for unmanned aerial vehicle charging cabinet, charging cabinet and system

Abstract

The invention discloses an anti-collision method and device for an unmanned aerial vehicle charging cabinet, the charging cabinet and a system. The method comprises the following steps: generating a request command, and transmitting the request command to an electronic tag on each unmanned aerial vehicle, enabling a memory of each electronic tag to generate a first random integer from 0 to n, and enabling the n to be an integer greater than or equal to 1; grouping the electronic tags according to the first random integer; endowing the electronic tags in each group with second random integers from 0 to m, wherein m is an integer larger than or equal to 1; establishing a particle swarm two-dimensional model, and determining an initial coordinate of each electronic tag in each group according to the second random integer; performing global optimization operation on each electronic tag in each group to enable each electronic tag to reach an optimal position; and recognizing the electronic tags in sequence according to the groups and the optimal positions; The method can effectively prevent collision of multiple unmanned aerial vehicle label responses.

Description

technical field [0001] The invention relates to the field of UAV charging control, in particular to an anti-collision method, device, charging cabinet and system for a UAV charging cabinet. Background technique [0002] With the modernization of social construction, unmanned aerial vehicles are widely used in various fields such as military, agriculture, industry, emergency rescue and disaster relief, surveying and mapping, etc., and the tasks are becoming more and more complicated. The increase of unmanned aerial vehicles makes its management more and more difficult, especially In terms of the management of UAV battery charging, there are currently charging cabinets on the market that can charge multiple UAVs at the same time. Seat, you can place multiple drones and charge them at the same time. When it is necessary to identify the charging UAV, radio frequency identification technology (RFID) can be used. For example, patent document CN105262187B discloses a charging meth...

Problems solved by technology

However, when the number of drones is large, there are multiple tags within the range of the antenna of a reader in the RFID application system. When the reader sends out a query command, it often causes multiple tags to respond at the same time. These response information Collisions occur on a shared wireless channel, making the response signal difficult to read by the reader, causing multi-tag collisions
