레이저 가이드 빔을 이용한 쿼드 로터 비행체 위치 홀딩 시스템

Abstract

Recently, Unmanned Aerial Vehicle(UAV) has been developed together with the aviation industry. As technology evolves, UAV of several types has been developed to boarding without person to automatic flight.

UAV were usually used for military purposes. But, Now, used in society from various forms, such as meteorological, environmental / forest fire surveillance, communications relay. Among these, research about unmanned aerial vehicle to perform the mission on behalf of the human has been developed in environment at difficult to reach such as a disaster area or a high-rise building.

UAV has fixed-wing airplane and rotor airplane. Rotor airplane is easy to control, that divided a single-rotor type(helicopters) and quad-rotor type. Quad-rotor type aircraft is flying using rotor with two pairs of symmetrical to each other. In this study, we chose to quad-rotor aircraft, is able to vertical take-off and landing and hovering.

UAV are used the human hard-to-reach areas, such as transmission tower or high-rise buildings. In these regions occurs electric wave shaded areas by high-voltage power lines. Using GPS in order to know about UAV position information. But, we can not know position information because electric wave shaded areas.

In this study, independent electromagnetic fields, possible to flying in area by many high-rise buildings to presented position holding system of the quad-rotor aircraft using laser guide beam. In this system, control the position using a photo-transistor array in UAV and that react laser guide beam on the ground.
