Embodiment Construction

[0048] The specific embodiment of the present invention is described in further detail below in conjunction with accompanying drawing:

[0049] see figure 1 , is a schematic diagram of a UAV-based swarm search and rescue method and system proposed by an embodiment of the present invention. As shown in the figure, after a person is in distress, the UAV formation formed by S102-S105 starts to search.

[0050] In the UAV formation, S103~S105 are search UAVs, and its structure is as follows: figure 2 shown. After starting the search and rescue, the search UAV uses the wireless micro base station simulation module to simulate the GSM network base station signal in the area it flies over. When the drone flies to the area where the person in distress is located, since there is no other wireless network, the mobile phone carried by the person in distress will actively initiate the registration process after searching for the wireless network generated by the drone.

Abstract

The invention discloses an unmanned aerial vehicles searching-based method and system. First, registration or residence information in personal mobile terminals of persons in distress is searched by using a personal wireless network simulated by unmanned aerial vehicles, information searched by different unmanned aerial vehicles is interacted through an unmanned aerial vehicle self-organizing network formed by communication modules of the vehicles, then information of identity and geographical positions of persons in distress is calculated and determined according to information of persons in distress acquired by unmanned aerial vehicles independently, and finally, combined information is returned to a ground station of a rescue center through a long-distance return module of a return unmanned aerial vehicle. According to the method and system, multiple different communication modules of the unmanned aerial vehicles are used to search and rescue persons in distress in a large range accurately and efficiently.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for searching and rescue based on unmanned aerial vehicles. Background technique [0002] With the continuous development of self-guided travel, various adventure and crossing activities are becoming more and more popular, and incidents of tourists and "donkey friends" in distress and disappearance frequently occur. [0003] However, since such incidents usually occur in inaccessible wilderness or areas without wireless network coverage, such as mountainous areas, people in distress cannot seek help from the outside world through common personal mobile terminals such as mobile phones. At the same time, the current search and rescue work mainly relies on the manual search and rescue method of rescuers pulling nets, which is inefficient and difficult to find people in distress. [0004] With the development of technology, the stagnation time, flight radi...
