Description

Method and system for collecting and transmitting unmanned information floating in the air

The present invention forms a triangular point by fastening a plurality of air collection drive in a semi-convex sphere of a predetermined angle, each air collection drive is formed with a plurality of cylindrical fans connected to the rotating body based on the intermediate drive rotation point When the rotation is given in a certain direction, when the columnar fan is rotated by a certain angle, the rotation stops and the lower direction starts to descend, it acts in the opposite direction of the columnar fan by the upwind and is fixed to the fixed body by the fixed end. It is formed to collect the lower wind so that the buoyancy is generated.

The main body, which is connected to the air collection propulsion unit and consists of each information collecting sensor, has a 3-axis gyroscope sensor, a temperature / humidity sensor, an altitude sensor, a wind speed measuring unit, and a processing unit for converting a predetermined value into information using the same; It is composed of a storage recorder for storing and recording in the form and a transmission unit for transmitting weather information to the receiver to collect weather information located on the ground, so that the control and adjustment that can be restored to the starting point of the main body.

As soon as possible to assure a rapid rise to a certain altitude, and after free fall below a certain altitude, the lifting fan is closed to create an air-conical cone to create a buoyancy to maintain the speed of falling down based on the buoyancy, and more Combines a large number of air collection props based on the center point for greater buoyancy and cover the case on the top to create a larger buoyancy to float in the air.

The rotation speed of the rotating body of the air collection propeller is controlled and controlled by the control processor for fixing, moving or turning in the place where information is collected. Input information from these paths and locations is transmitted from an external processing receiver, and a processing unit is set up to automatically return to the starting point after all processing is completed.

Recently, the development of unmanned aerial vehicles (UAVs) for exploration and reconnaissance has been actively developed due to the rapid development of aviation technology and communication technology, and these drones are dangerous to be carried by humans directly. This has the advantage of enabling difficult tasks.

The flight of the unmanned aerial vehicle includes an inertial navigation system for navigation equipment, a speedometer, an altimeter, and attitude control, and a GPS (Global Positioning System) for route guidance.

The inertial navigation system consists of a gyroscope and an accelerometer called an inertial sensor, and measures the rotational angular velocity and linear acceleration of the unmanned aerial vehicle, and provides information on the current position, speed, altitude, azimuth, and flight attitude of the unmanned aerial vehicle. To provide. In other words, if the unmanned aerial vehicle is integrated two times in three-axis acceleration from the moment when the unmanned aerial vehicle starts to an arbitrary time, the flight distance is obtained, and thus the current position can be known. However, for long flight time, it is difficult to fly for a long time because it must be driven or a rotor that must always generate lift, such as a rotorcraft.

FLYING BODY of 1020100113141 (20101020), which is openly applied, is an upper blower composed of a rotating impeller that pumps air in an axial flow direction. The upper blower is composed of a skirt-shaped fixed blade in which the upper blower is concentrically arranged. It is not the principle of the method of applying the buoyancy of the device which is lowered to the device to obtain the thrust by switching the power, and the flight control system and control method of the unmanned aerial vehicle of the disclosed 1020100016915 (20100216) The vehicle can recognize the failure caused by the navigation equipment, the speedometer, and the altimeter, and excludes the current position, flight posture, azimuth, speed, and altitude measured by the navigation equipment, the speedometer, and the altimeter where the failure has occurred. Flight control device of unmanned aerial vehicle capable of selectively inputting current position, flight attitude, azimuth, speed, and altitude Fixed-wing method for controlling a vehicle of the way floating by on the speedometer, such as the control method between the speed control and other devices, such as for keeping the lift for the aircraft as a control method for unmanned aircraft flying to the control method is not.

In order to improve the above limitations, a long flight time is ensured by floating in the air by using a plurality of air collecting propulsion bodies that can continuously perform the operation of raising or lowering the altitude above a predetermined path and location, and the body itself Auto-reversible function

According to the initial setting information input, the main body rises through the triangular-shaped air collection propulsion unit so that lift force is generated for the main body floating in the air to maintain the constant altitude up to a certain altitude, and at the same time stops the rotating body according to the altitude. Lifting fan is converted to the angle to collect the air, and the air collection cap and air collection case by the body is free buoyancy is formed floating even when free fall. For the movement of the position and the change of direction, the control processing unit can adjust the rotation speed of the rotating body for each air collection propulsion unit, and the control processing unit has a communication unit that can transmit and receive with the outside.

For the safe ground attitude control of the main body, the lower part has a buffer support so that the main body can take off and land regardless of the terrain. In addition, the control processing unit is modularized to be used in accordance with the intended use (unmanned reconnaissance, weather measurement, communication relay, etc.) to be combined and used for each purpose. And an information collecting processor for transmitting initial setting information to the control processor so as to arbitrarily adjust the usage method in real time from the outside, and receiving, displaying, processing, and storing the collected information transmitted from the control processor.

It is equipped with integrated sensors such as temperature and humidity to collect weather and various information to reduce the weight, but it can operate the 3-axis gyroscope and GPS sensor to collect the equilibrium and current position of the body. Configure on location. In order to collect the image information of the ground below when it is raised above, an image sensor is mounted at the bottom of the control processing unit, and the flight posture, the route, the current position and the altitude are calculated based on the collected information. Control and control functions of the control processor to adjust posture and position.

It is configured to collect air to descend at the lowest speed every time. A sensor that checks the equilibrium state of the rotating propulsion fluid at all times by constructing a convex parachute structure that connects a large number of air collection propellers to a triangular center point that can raise the body in a balanced manner and form buoyancy when descending In the control processing unit, it is raised by adjusting the individual operating strength, and when the initial altitude input value is reached, the lifting fan of the rotating body is stopped and the lifting fan in the air collection body is locked and the cap is induced. When descending, the speed is reduced to collect information.

Combine the balloon for greater buoyancy so that it floats in the air for a long time. It is an object of the present invention to provide a floating flight method and a system capable of maintaining buoyancy in a long time by performing various functions by modularizing and combining an intermediate assembly of a control processing unit.

As described above, according to the present invention, the main body is automatically raised on the basis of external input information, so that a long time flight is possible to the information collection floating on the information collection place and path, so that high-air measurement in the shortest time, Regardless of the weather and the terrain, the role of communication relay and takeoff and landing can fly freely for a long time to collect and transmit information.
