A WiFi-supported air-ground collaborative UAV system

Abstract

The invention relates to an air-ground coordination unmanned plane system supported by WiFi. The system comprises an information acquisition and control subsystem arranged on an unmanned plane, and an information processing subsystem and a wireless sensing network arranged on ground. The information acquisition and control subsystem and the information processing subsystem are provided with WIFI communication units. The WIFI communication units in the information acquisition and control subsystem and the information processing subsystem are connected through the wireless sensing network in a communication manner. The information acquisition and control subsystem on the unmanned plane acquires signal intensity information on each wireless node in the wireless sensing network, and sends the information to the information processing subsystem on ground. The information processing subsystem processes the information and obtains geographical location information of the unmanned plane and carries out navigation. Compared with the prior art, the system makes full use of a WiFi channel to transmit data of an unmanned plane and ground. The system is convenient in realization and low in cost, and large amount of data processing process is performed on ground, so as to reduce power consumption of the unmanned plane.

Description

technical field [0001] The invention relates to an air-ground navigation unmanned aerial vehicle system, in particular to an air-ground cooperative unmanned aerial vehicle system supported by WiFi. Background technique [0002] With the continuous advancement of science and technology, civilian small UAVs have been widely used in various fields. On the military side, UAVs can be applied to tasks such as air early warning, reconnaissance and surveillance, communication relay, target attack, electronic countermeasures, and intelligence acquisition; on the civilian side, UAVs can be applied to meteorological observation, terrain survey, and urban environmental monitoring , artificial rainfall, forest fire warning and aerial photography, etc. When emergencies such as earthquakes, mudslides, forest fires, and major traffic accidents occur, it is very important to be able to respond immediately and save people's lives and property in time. However, rescuers are often unable to a...
