Description

무인기를 이용한 풍향 및 풍속 수직분포 측정 시스템 및 방법{SYSTEM AND METHOD FOR MEASURING VERTICAL DISTRIBUTION OF WIND DIRECTION AND SPEED USING UNMANNED PLANE} BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for measuring wind direction and wind velocity vertical distribution using a UAV,

본 발명은 풍향 및 풍속 측정 시스템 및 방법에 관한 것으로 더욱 상세하게는 무인기를 이용한 풍향, 풍속 수직분포를 측정하는 시스템 및 방법에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction and wind speed measurement system and method, and more particularly, to a system and method for measuring vertical wind direction and wind speed using a UAV.

대기중의 풍향, 풍속, 온도, 습도 등 기상학적 인자의 수직분포를 측정하기 위하여 기존에는 존데(Sonde)를 사용하였다. 이러한 기상존데는 한 번 사용하면 재사용을 할 수 없어 비용이 많이 드는 문제점이 있었다. 특히 풍향, 풍속의 수직분포를 정확히 측정해야만 비행기의 이착륙, 정확한 일기 예보 등을 할 수 있었다. 이러한 문제점을 해결하기 위해 무인기(Multi-copter)와 같은 비행체에 풍향, 풍속의 수직 분포를 측정할 경우 하루에도 여러 번 측정이 가능하며, 운용 비용도 획기적으로 줄일 수 있다.In order to measure the vertical distribution of meteorological factors such as wind direction, wind speed, temperature and humidity in the atmosphere, Sonde was used. Such a weather sonde can not be reused once it is used, which is costly. Especially, it was necessary to accurately measure the vertical distribution of wind direction and wind speed to take off and land the aircraft, and to make precise weather forecasts. In order to solve this problem, it is possible to measure the vertical distribution of the wind direction and the wind speed on the airplane such as a multi-copter several times a day, and the operation cost can be drastically reduced.

기존의 존데 방식은 헬륨(수소)가스를 주입한 풍선을 띄워 바람에 따라 풍선이 움직이면 풍선의 위치를 계산하여 바람의 수직 분포를 측정하였다. 이러한 방법은 풍선의 재 사용이 불가능하여 공항이나, 기상관측소에서 바람의 수직분포를 측정하기 위하여 사용되는 비용이 상당히 많았다. In the conventional sonde method, the helium (hydrogen) gas was injected into the balloon, and when the balloon moved according to the wind, the position of the balloon was calculated and the vertical distribution of the wind was measured. This method can not be used again because the balloon can not be used at the airports and weather stations to measure the vertical distribution of wind was very expensive.

기존의 풍향 풍속측정 장치는 여러 가지가 있으나 멀티콥터와 같이 계속 움직이면서 풍속을 측정할 경우 기존의 cup anemometer나, 프로펠러형 anemometer는 사용하기가 힘들다.  Although there are many existing wind speed measuring devices, it is difficult to use a conventional cup anemometer or a propeller type anemometer to measure wind speed while moving continuously like a multi-copter.

기존의 초음파나 hot-wire 풍속계에 지자기 센서를 부착하여 멀티콥터의 방향에 상관없이 지자기 센서의 자북(磁北)과 연동하여 풍향을 계산하여 정확한 풍향을 측정하는 것과, 멀티콥터가 비행중에 항상 일정방향만을 향하게 하여 풍향을 측정하는 것에 관한 것이다. 그러나 이러한 방법도 풍속이 강할 경우 비행체의 수평이 깨져 바람부는 방향으로 비행체의 몸체가 경사지게 된다. 이러한 경우 비행체의 몸체에 풍속측정장치가 고정되어 있으면 정확한 풍속을 측정하기 어려워진다. It is necessary to measure the wind direction by measuring the wind direction in conjunction with the magnetic north of the geomagnetic sensor regardless of the direction of the multi-copter by attaching the geomagnetic sensor to the existing ultrasonic wave or hot-wire anemometer, To measure the wind direction. However, in this method, if the wind velocity is strong, the body of the flight body is inclined toward the wind direction because the level of the flight body is broken. In this case, it is difficult to measure the accurate wind speed if the wind speed measuring device is fixed to the body of the aircraft.

본 발명은 멀티콥터(Multi-copter)에 초음파 풍향, 풍속계를 설치하여 바람의 방향과 속도의 수직 분포를 측정할 수 있는 시스템에 관한 것이다. The present invention relates to a system capable of measuring a vertical distribution of wind direction and velocity by installing an ultrasonic wave anemometer in a multi-copter.

본 발명은 멀티콥터에 초음파 풍속계 또는 hot-wire anemometer를 설치하여 멀티콥터가 수직 상승하면서 풍향과 풍속을 측정하고 동시에 온도와 습도, 고도, 압력 등 기상요소를 측정하여 지상으로 전송하고 임무가 종료되면 지상으로 되돌아와서 배터리 충전 후 바로 재사용할 수 있는 시스템에 관한 것이다.In the present invention, an ultrasonic anemometer or a hot-wire anemometer is installed in a multi-copter to measure a wind direction and an air speed while vertically ascending a multi-copter. At the same time, a weather element such as temperature, humidity, altitude and pressure is measured and transmitted to the ground. To a system that can return to the ground and reuse immediately after charging the battery.

본 발명은 풍속측정장치를 짐벌(gimbals) 또는 Pivot bearing 등에 장착하여 수평을 유지시켜 정확한 풍향과 풍속을 측정할 수 있다.The present invention can measure the wind direction and the wind speed accurately by installing the wind speed measuring device on a gimbals or a pivot bearing or the like and keeping it horizontal.

본 발명의 일 실시 예에 따르면, 본 발명품은 기존에 사용되고 있는 Sonde를 대체하여 재사용이 가능하고 유지비용을 줄일 수 있을 뿐만 아니라 고정된 고도에서 지속적으로 풍향-풍속을 측정할 수 있다.According to an embodiment of the present invention, the present invention can replace wind turbines that are used in the past and can be reused, reduce maintenance cost, and can continuously measure the wind direction-wind speed at a fixed altitude.

본 발명의 일 실시 예에 따르면, 무인기에 초음파 풍속계 또는 hot-wire anemometer를 설치하여 무멀티콥터가 수직 상승하면서 풍향과 풍속을 측정하고 동시에 온도와 습도, 고도, 압력 등 기상요소를 측정할 수 있다.According to one embodiment of the present invention, an ultrasonic anemometer or a hot-wire anemometer is installed in a UAV, so that a multi-copter can vertically ascend and measure a wind direction and an air speed while measuring a temperature element such as temperature, humidity, .

도 1 및 도 2는 본 발명의 일 실시 예에 따른 풍향 및 풍속 수직분포 측정 시스템를 설명하기 위한 도면들이다. 1 and 2 are views for explaining a wind direction and wind velocity vertical distribution measuring system according to an embodiment of the present invention.

대기 기상환경의 수직분포를 종래에는 풍선에 온도, 습도, 통신기 등을 부착해서 일정 시간마다 일회성 라디오 존데를 이용하였다. 따라서 운영비용이 많이 드는 문제점이 있고, 존데의 경우 일정한 높이에서 연속적을 측정할 수 없는 문제점이 있었다. 이에 본 발명은 일정한 고도에 장시간 머물며 풍향 및 풍속의 변화를 관측할 수 있으며, 충전을 하여 연속 사용이 가능하다. The vertical distribution of the atmospheric environment was conventionally used by using a one - time radio - sonde at fixed intervals by attaching temperature, humidity, and communication device to the balloon. Therefore, there is a problem that operation cost is high, and there is a problem that continuous measurement can not be performed at a constant height in case of sonde. Accordingly, the present invention can observe a change in wind direction and wind speed while staying at a certain altitude for a long time, and can be continuously used by charging.

본 발명은 멀티콥터에 초음파 풍속계 또는 hot-wire 풍속계 (이하 풍향-풍속계)를 장착하여 대기중 풍향과 풍속의 수직 분포를 측정할 수 있는 시스템에 관한 것이다. 멀티콥터에 풍향-풍속계를 장착하면 멀티콥터가 회전(자전)하이므로 이에 대한 보정을 하거나 멀티콥터 몸체의 방향이 항상 일정한 방향을 지향하도록 운영하여야만 정확한 풍향을 측정할 수 있다. 또한 풍속이 강할 경우 멀티콥터의 몸체가 바람이 불어오는 방향쪽으로 기울어지게 되는데, 이러한 문제점을 극복하기 위해 풍향-풍속계를 짐벌 또는 pivot bearing에 장착하여 풍향풍속계 자체가 수평을 유지하도록 하여 풍속과 풍향을 정확히 측정할 수 있도록 한다.The present invention relates to a system capable of measuring the vertical distribution of wind direction and wind speed in the air by installing an ultrasonic anemometer or a hot-wire anemometer (hereinafter referred to as an anemoscope) in a multi-copter. Since the multi-copter is rotated when the wind direction-anemometer is installed in the multi-copter, it is necessary to correct it or operate the multi-copter body so that the direction of the body is always constant. In addition, when the wind speed is high, the body of the multi-copter is inclined toward the wind direction. To overcome this problem, the wind direction-anemometer is mounted on the gimbals or the pivot bearing so that the wind direction anemometer maintains its horizontal position, Make accurate measurements.

도 1을 참조하면, 본 발명에 따른 풍향 및 풍속 수직분포 측정 시스템 및 방법은 풍향-풍속계가 짐벌위에 장착되어 풍향-풍속계가 수평을 유지하도록하여 정확한 풍향과 풍속을 측정할 수 있다. Referring to FIG. 1, the wind direction and anemometer measurement system and method according to the present invention can measure accurate wind direction and wind speed by mounting a wind direction-anemometer on the gimbals and keeping the wind direction-anemometer horizontal.

도 2를 참조하면, 본 발명에 따른 풍향 및 풍속 수직분포 측정 시스템 및 방법은 도 1의 짐벌 대신 풍향-풍속계가 수평을 유지할 수 있도록 pivot bearing을 관통하는 축의 상부에 풍향-풍속계를 장착하고, 축의 하부에 일정한 무게를 갖는 물체(추)를 달아서 이 무게에 의해 멀티콥터의 몸체가 기울어져도 추의 무게에 의해 풍향-풍속계는 수평을 유지할 수 있다. 따라서 본 발명에 따른 풍향 및 풍속 수직분포 측정 시스템 및 방법은 정확한 풍향-풍속을 측정할 수 있다. 이때 pivot bearing에 의해 축이 회전할 경우 풍향-풍속계도 자전에 의해 방향이 바뀔 수 있어 이를 보정하기 위해 지자기센서에 의해 보정을 할 수 있다. Referring to FIG. 2, the wind direction and wind velocity vertical measurement system and method according to the present invention is characterized in that a wind direction-anemometer is mounted on an axis passing through a pivot bearing so that a wind direction- Even if the weight of the multi-copter is tilted by this weight by attaching an object (weight) having a certain weight to the bottom, the wind direction-anemometer can be kept horizontal by the weight of the weight. Therefore, the wind direction and wind speed vertical distribution measurement system and method according to the present invention can measure accurate wind direction-wind speed. At this time, if the shaft is rotated by the pivot bearing, the direction of the wind direction-anemometer can be changed by the rotation, and the correction can be performed by the geomagnetic sensor to correct the direction.
