Problems solved by technology

Its shortcomings are: on the one hand, it is affected by the layout and height of the UAV, and the positioning accuracy is low; The signal sent by the mobile terminal of the person in distress may cause the failure of the search and positioning; in addition, this scheme lacks information review links, and is not suitable for searching for hidden targets, and its practicability is weak

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0028] Such as figure 1 with figure 2 As shown, in the UAV swarm search and rescue method of this embodiment, a plurality of search UAVs form a UAV swarm, respectively carry detection sources to scan the area to be searched, and determine suspected areas. The detection sources include radio spectrum detection sources, and / or SAR imaging detection source, and / or optical imaging detection source; determine the target area from the suspected area through data fusion; scan the target area by searching the ultra-wideband life detection radar carried by the drone, acquire and return the target area vital sign status information.

[0029] In this embodiment, different detection sources are used to scan the same area to be searched to detect suspected areas respectiv...

Abstract

The invention discloses a UAV group search and rescue method and system. The method comprises forming a UAV group by a plurality of search UAVs each carrying a detection source to scan to-be-searchedareas to determine suspected areas, wherein the detection source comprises a radio spectrum detection source, and / or a SAR imaging detection source, and / or an optical imaging detection source; determining a target area from the suspected areas by data fusion; scanning the target area by ultra-wideband life detection radars carried by the UAVs, acquiring and returning vital sign state information in the target area. The method and system have the advantages of accurate search and rescue positioning, high precision, good flexibility and good stability, can greatly improve the efficiency of search and rescue.

Description

technical field [0001] The present invention relates to the technical field of rescue, in particular to a search and rescue method and system for unmanned aerial vehicle swarms. Background technique [0002] After large-scale natural disasters, such as earthquakes and landslides, the original roads and passages are destroyed, and the normal channels for rescuers and facilities to enter the disaster area are blocked. Because it is uncertain that no survivors will be trapped on the road, large-scale rescue equipment should not rush into the disaster area. To avoid secondary injuries, the entry time is relatively late, which hinders the detection of the existence of living organisms and rescue; the search and rescue helicopter dispatch is limited by technology and support conditions, with few sorties, no fixed equipment, and personnel safety is difficult to guarantee; Various types of vital sign target detection and rescue equipment are carried by people into the disaster area....
