Description

풍향 풍속계{anemoscope and anemometer}Wind direction anemometer

본 발명은, 풍향 풍속계에 관한 것으로서, 보다 상세하게는 휴대가 간편하며, 측정부가 회전하지 않으며 풍향 및 풍속을 동시에 측정할 수 있는 풍향 풍속계에 관한 것이다.The present invention relates to a wind direction anemometer, and more particularly, to a wind direction anemometer, which is easy to carry, and which can measure the wind direction and the wind speed at the same time without the measurement unit rotating.

자연현상의 하나인 바람은 일상생활에 있어서 많은 영향을 미친다. 일반적으로 골프장, 야구장 등과 같은 레저현장 및 항공기, 선박 등과 같은 수송분야, 대기중의 연기의 확산현상조사 및 통풍환기 등의 환경분야, 건설분야, 발전분야, 군사분야 등 여러 분야에서 바람은 사람들의 활동을 제약하기도 하며, 또한 유용하게 이용되기도 한다.Wind, one of natural phenomena, has a lot of influence in daily life. In general, leisure fields such as golf courses and baseball fields, transport fields such as aircraft and ships, air pollution diffusion phenomenon and environmental fields such as ventilation and ventilation, construction fields, power generation fields, military fields, etc. They can also restrict activity and can be useful.

이에, 종래에는 기상대나 관측소의 광역적인 지역의 바람의 정보를 이용하거나, 프로펠러식 자기 풍향 풍속계 등을 소정의 위치에 설치하여 풍향 및 풍속을 측정하여 왔다.Therefore, in the past, wind direction and wind speed have been measured by using wind information of a wide area of a weather station or an observation station, or by installing a propeller type wind vane at a predetermined position.

또한, 종래에는 5㎛ 정도의 굵기를 가진 한쌍의 열선을 엇갈리게 설치하여 각 열선에 흐르는 전류를 검출함으로써, 풍속을 측정하는 실험실용 풍속계가 개발되어 왔다.In addition, conventionally, a laboratory anemometer for measuring wind speed has been developed by staggering a pair of hot wires having a thickness of about 5 μm and detecting a current flowing through each hot wire.

그런데, 이러한 종래의 풍향 풍속계에 있어서, 프로펠러식 자기 풍향 풍속계의 경우 휴대가 곤란하여 국부적인 장소에서만 풍향 및 풍속을 측정할 수 있으며, 또한 그 구조가 복잡하고 설치공간이 소요되는 문제점이 있다. 그리고, 실험실용 풍향 풍속계의 경우 측정부는 휴대가 가능하나 측정부로부터 나오는 복잡한 신호를 분석하기 위한 고가의 신호분석기 등의 부대 장비가 필요하며, 열선의 굵기가 과도하게 작아 열선이 쉽게 손상되어 내구성이 적어 유지관리가 곤란할 뿐만 아니라 먼지 등의 이물질이 열선에 쉽게 부착되어 풍속의 측정 정밀도가 저하되는 문제점이있다.By the way, in the conventional wind direction anemometer, propeller type wind direction anemometer is difficult to carry, so it is possible to measure the wind direction and wind speed only in a local place, and there is a problem in that the structure is complicated and the installation space is required. In the case of the laboratory wind anemometer, the measuring part is portable, but additional equipment such as an expensive signal analyzer for analyzing a complex signal from the measuring part is required.The thickness of the heating wire is excessively small so that the heating wire is easily damaged and durable. Not only is it difficult to maintain, but there is a problem that foreign matter such as dust is easily attached to the hot wire, thereby degrading the measurement accuracy of the wind speed.

따라서, 본 발명의 목적은, 구조가 간단하고 휴대가 간편하며, 내구성이 증대되어 유지관리가 용이하고, 측정부가 회전하지 않으며 정밀하게 풍향 및 풍속을 동시에 측정할 수 있는 풍향 풍속계를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a wind direction anemometer in which the structure is simple and portable, the durability is increased, the maintenance is easy, and the measurement unit does not rotate, and the wind direction and the wind speed can be precisely measured simultaneously.

도 1은 본 발명에 따른 풍향 풍속계의 개략적인 블록 구성도이고, 도 2는 본 발명에 대한 제1실시예로서 풍향 풍속계를 구성하는 측정부와 지지부의 사시도이며, 도 3은 도 2의 좌측면도이다. 이들 도면에 도시된 바와 같이, 본 발명에 따른 풍향 풍속계는, 풍향 및 풍속을 측정하는 3개의 측정부(1)와, 측정부(1)들을 절연 지지하는 지지부(3)와, 측정부(1)에 전원을 공급하는 전원공급부(11)와, 측정부(1)로 흐르는 전류량을 검출하는 검출부(13)와, 검출부(13)에 의해 검출된 전류량으로부터 풍향 및 풍속을 산출하는 콘트롤러(15)를 가진다. 또한, 풍향풍속계는 지지부(3)로부터 연장되어 각 측정부(1)가 설치되는 3개의 설치면(5a)을 구비한 연장지지부(5)를 가진다. 여기서, 전원공급부(11)는 측정부(1)로 일정의 전압을 가진 전원을 공급하는 것이 바람직하다.1 is a schematic block diagram of a wind vane according to the present invention, Figure 2 is a perspective view of the measuring unit and the support constituting the wind vane as a first embodiment of the present invention, Figure 3 is a left side view of FIG. to be. As shown in these figures, the wind direction anemometer according to the present invention includes three measuring units 1 for measuring the wind direction and the wind speed, a support unit 3 for insulatingly supporting the measuring units 1, and a measuring unit 1. A power supply unit 11 for supplying power to the power supply unit 11, a detection unit 13 for detecting an amount of current flowing through the measuring unit 1, and a controller 15 for calculating wind direction and wind speed from the amount of current detected by the detection unit 13 Has The wind vane also has an extended support 5 having three mounting surfaces 5a extending from the support 3 and on which the respective measurement sections 1 are installed. Here, the power supply unit 11 preferably supplies power having a predetermined voltage to the measurement unit 1.

지지부(3)는 절연부재로 이루어져 있으며 소정의 측정위치에 고정 설치가 가능하도록 원통형의 관상체로 형성되어 있다. 지지부(3)의 내주면에는전원공급부(11)로부터 각 측정부(1)로 전원을 공급하는 복수의 전선(9)이 관통한다. 여기서, 지지부(3)는 원통형의 관상체 이외에 다각형의 관상체로 형성될 수 있음은 물론이다. 또한, 도시되어 있지 않지만, 지지부(3)의 외주면에는, 지지부(3)를 소정의 측정위치에 확고히 고정 설치하기 위해, 브래킷을 마련하거나 나사 등을 형성할 수도 있다.The support part 3 is made of an insulating member and is formed of a cylindrical tubular body to be fixedly installed at a predetermined measurement position. On the inner circumferential surface of the support part 3, a plurality of electric wires 9 for supplying power from the power supply part 11 to each measurement part 1 penetrate. Here, the support 3 may be formed of a polygonal tubular body in addition to the cylindrical tubular body. Although not shown, a bracket or a screw may be provided on the outer circumferential surface of the support part 3 so as to securely install the support part 3 at a predetermined measurement position.

지지부(3)의 일단부에는 측정부(1)가 설치되는 3개의 설치면(5a)을 가지며 3면체를 형성하는 연장지지부(5)가 마련되어 있다. 연장지지부(5)의 각 설치면(5a)은 등각도를 이룬다. 연장지지부(5)의 각 설치면(5a)에는 일정온도를 유지하면서 외부로 열을 발산하는 측정부(1)가 설치되고, 연장지지부(5)의 단부면에는 측정부(1) 주위의 온도를 측정하는 온도센서(7)가 설치되어 있다. 연장지지부(5)는 절연부재로 이루어져 있고, 따라서 각 측정부(1)는 상호 절연이 된다.One end of the support part 3 is provided with an extended support part 5 having three mounting surfaces 5a on which the measurement part 1 is provided and forming a trihedron. Each installation surface 5a of the extension support part 5 forms an isometric angle. Each installation surface 5a of the extended support 5 is provided with a measurement unit 1 for dissipating heat to the outside while maintaining a constant temperature, and the temperature around the measurement unit 1 on the end surface of the extended support 5. The temperature sensor 7 for measuring the pressure is provided. The extended support part 5 is made of an insulating member, so that each measuring part 1 is insulated from each other.

한편, 각 측정부(1)는 반도체의 도전율이 주위 온도변화에 민감한 것을 이용한 전자회로용 소자인 판상의 포지스터(positive temperature coefficient thermistor)로 이루어지며, 연장지지부(5)의 각 설치면(5a)에 밀착 설치되어 있다. 또한, 각 측정부(1)의 외측면에는 먼지 등의 이물질이 부착되는 것을 방지하기 위해 보호막으로 코팅되어 있다. 그리고, 각 측정부(1)의 일단부는 전선(9)에 의해 전원공급부(11)와 연결되어 있다.On the other hand, each measuring unit 1 is composed of a plate-shaped positive electrode (positive temperature coefficient thermistor) that is an element for an electronic circuit using the conductivity of the semiconductor is sensitive to changes in ambient temperature, each mounting surface (5a) of the extension support (5) ) Is installed in close contact. In addition, the outer surface of each measuring unit 1 is coated with a protective film to prevent foreign matter such as dust from adhering. One end of each measurement unit 1 is connected to the power supply unit 11 by an electric wire 9.

이러한 구성에 의해, 전원공급부(11)로부터 일정 전압을 가진 전원을 측정부(1)에 인가하게 되면, 각 측정부(1)는 일정온도를 유지하면서 외부로 일정의 열량을 발산하게 된다. 항온 특성을 가지는 측정부(1)는 바람과의 접촉에 의해 온도 변화가 발생하여 냉각되며, 특히 풍속에 따라 측정부(1)의 냉각되는 열량은 달라지게 된다. 즉, 풍속이 커짐에 따라 측정부(1)의 냉각되는 열량은 커지게 된다. 이에, 냉각된 측정부(1)는 항온을 유지하기 위해 냉각된 열량의 보충이 필요하게 되어, 냉각된 측정부(1)로 흐르는 전류량은 증대하게 된다.With this configuration, when a power source having a constant voltage is applied from the power supply unit 11 to the measuring unit 1, each measuring unit 1 emits a certain amount of heat to the outside while maintaining a constant temperature. The measuring unit 1 having a constant temperature characteristic is cooled due to a temperature change generated by contact with the wind, and in particular, the amount of heat to be cooled in the measuring unit 1 varies according to the wind speed. That is, as the wind speed increases, the amount of heat to be cooled in the measurement unit 1 increases. Thus, the cooled measuring unit 1 needs to replenish the cooled amount of heat in order to maintain the constant temperature, so that the amount of current flowing into the cooled measuring unit 1 increases.

따라서, 지지부(3)를 풍향 및 풍속을 측정하고자 하는 위치에 고정설치하고, 측정부(1)들을 바람을 측정하고자 하는 영역에 노출시키면, 바람에 대향하는 측의 측정부(1)는 바람과 대향하지 않는 측의 측정부(1)에 비해 상대적으로 더 냉각되어 전류량의 소모가 증대된다. 이 때, 검출부(13)에서 각 측정부(1)로 흐르는 전류량을 검출하여, 검출된 전류량을 콘트롤러(15)에 제공한다.Therefore, when the support part 3 is fixedly installed at the position where the wind direction and the wind speed are to be measured, and the measuring units 1 are exposed to the area to be measured, the measuring unit 1 on the side opposite to the wind is connected to the wind. Compared with the measuring part 1 of the non-opposing side, it cools relatively, and the consumption of an amount of electric current increases. At this time, the detection unit 13 detects the amount of current flowing to each measurement unit 1 and provides the detected amount of current to the controller 15.

그리고, 콘트롤러(15)에서는 각 측정부(1)로 흐르는 전류량을 상호 비교하게 된다. 이 때, 바람의 온도와 각 측정부(1)에서 소모되는 전류량은 상관관계를 가지므로, 콘트롤러(15)는 온도센서(7)에서 측정한 바람의 온도에 따라 각 측정부(1)에서 소모된 전류량을 적절히 보정하게 된다.In addition, the controller 15 compares the amount of current flowing to each measurement unit 1 with each other. At this time, since the temperature of the wind and the amount of current consumed by each measuring unit 1 have a correlation, the controller 15 consumes at each measuring unit 1 according to the temperature of the wind measured by the temperature sensor 7. Corrected current amount is appropriately corrected.

이로써, 콘트롤러(15)를 통해 어느 위치의 측정부(1)로 전류량이 많이 소모되었는지를 판단하여, 풍향을 산출할 수 있게 된다. 또한, 측정부(1)에서 소모된 전류량에 의해 풍속을 정밀하게 산출할 수 있게 된다.As a result, it is possible to calculate the wind direction by determining whether the amount of current is consumed by the measuring unit 1 at which position through the controller 15. In addition, the wind speed can be accurately calculated by the amount of current consumed by the measuring unit 1.

여기서, 각 측정부(1)가 설치되는 연장지지부(5)는 3면체를 형성하는 것으로 한정하고 있지만, 이에 한정하지 않고 연장지지부(5)는 다수의 측정부(1)가 설치 가능하도록 다양한 패턴의 다면체로 형성될 수 있음은 물론이다.Here, although the extended support part 5 on which each measurement part 1 is installed is limited to forming a trihedron, the present invention is not limited thereto, and the extended support part 5 may have various patterns so that a plurality of measurement parts 1 can be installed. Of course, it can be formed into a polyhedron.

또한, 전술한 실시예에서는, 각 측정부(1)가 연장지지부(5)의 각 설치면(5a)에 밀착 설치되는 것으로 설명하고 있지만, 각 측정부(1)의 일단부를 연장지지부(5)의 외측면으로부터 돌출되게 설치하여 각 측정부(1)를 연장지지부(5)를 중심으로 방사상으로 설치할 수도 있다.In addition, in the above-mentioned embodiment, although it is demonstrated that each measuring part 1 is installed in close contact with each installation surface 5a of the extended support part 5, the one end part of each measuring part 1 is extended and supported part 5 Protruding from the outer surface of the can also be installed radially around each of the measuring section (1) the extended support (5).

한편, 도 4 및 도 5는 본 발명의 제2실시예로서, 전술한 제1실시예와는 달리, 판형상을 가진 한쌍의 측정부(1)가 지지부(3)의 일단부면으로부터 소정 길이만큼 돌출 설치되어 있다. 또한, 각 측정부(1)는 소정의 각도를 형성하며 소정 거리 이격 설치되어 있다.On the other hand, Figure 4 and 5 is a second embodiment of the present invention, unlike the first embodiment described above, a pair of measuring unit 1 having a plate shape is a predetermined length from one end surface of the support portion 3 It is installed to protrude. In addition, each measurement part 1 forms a predetermined angle, and is installed in a predetermined distance.

이로써, 지지부(3)로부터 돌출 설치된 각 측정부(1)에 전원을 공급함으로써, 풍향을 측정할 수 있음과 동시에 2차원적 풍속도 측정할 수 있으며, 본 발명의 목적을 달성할 수 있게 된다.Thus, by supplying power to each measuring unit 1 protruding from the supporting unit 3, the wind direction can be measured and the two-dimensional wind speed can be measured, and the object of the present invention can be achieved.

이와 같이, 지지부에 일정온도를 유지하면서 외부로 열을 발산하는 측정부를 마련하고 각 측정부에 전원을 공급함으로써, 측정부가 회전하지 않으며 각 측정부로 흐르는 전류량에 따라 풍향 및 풍속을 동시에 측정할 수 있다. 또한, 구조가 간단하고 휴대가 간편하며, 내구성이 증대되어 유지관리를 용이하게 할 수 있다.As such, by providing a measuring unit for dissipating heat to the outside while maintaining a constant temperature in the support unit and supplying power to each measuring unit, the measuring unit does not rotate and simultaneously measures the wind direction and the wind speed according to the amount of current flowing to each measuring unit. . In addition, the structure is simple, easy to carry, and durability can be increased to facilitate maintenance.
