본 발명은 메인반사판으로부터 서브반사판의 위치 보정을 가능하도록 하여 위성신호의 수신효율을 유지 및 증대시키며, 서브반사판의 위치 가변이 가능함으로써 서로 다른 크기 또는 곡률을 가지는 메인반사판에 모두 적용할 수 있도록 하는 위성신호 수신장치와 이를 이용한 위성신호 수신 안테나 및 위성신호 수신방법에 관한 것이다.The present invention maintains and increases the reception efficiency of the satellite signal by enabling the position correction of the sub reflector from the main reflector, and the position of the sub reflector can be changed so that it can be applied to both main reflectors having different sizes or curvatures. A satellite signal receiving apparatus, a satellite signal receiving antenna and a satellite signal receiving method using the same.

일반적으로, 위성신호의 수신을 위해서 파라볼릭 형태의 안테나가 사용되고 있고, 이러한 파라볼릭 안테나는 반사면에 포물면을 사용한 지향성 안테나로서, 위성신호를 일정 방향으로 집중하여 송수신할 수 있으며, 이득 및 효율면에서 우수하고, 이로 인해 위성을 이용한 통신이나 위성방송의 수신 등에 사용된다.In general, a parabolic antenna is used for reception of a satellite signal. The parabolic antenna is a directional antenna using a parabolic surface on a reflective surface, and can transmit and receive a satellite signal in a certain direction, and gain and efficiency aspects. It is excellent in, and therefore is used for communication using satellite or reception of satellite broadcasting.

위성방송 수신의 경우 지상방송국에서 발사된 방송신호를 약 35,000∼36,000km 적도 상공의 정지궤도 상에 위치한 위성이 이를 중계하여 지상으로 재발사하면 각 가정에 설치되어 있는 위성방송 수신용 안테나가 이를 수신하여 그와 연 결된 위성방송 수신기로 전송시킴으로써 시청자가 TV 수상기를 통해서 위성방송을 시청하도록 하며, 소정의 주파수 범위 안에서 난시청 지역 없이 선명한 화면과 완벽한 음향을 제공할 수 있어 시청자들로부터 날로 각광을 받고 있을 뿐만 아니라 최근에는 일반 가정까지 널리 보급되고 있는데, 이러한 위성방송은 통상 3∼13GHz 범위의 SHF(Super High Frequency) 주파수신호를 수신하기 위해 적절한 수신장치가 요구되며, 기존의 3∼30MHz의 VHF(Very High Frequency), 30MHz∼3GHz의 UHF(Ultra High Frequency) 전파에 비하여 지상에 미치는 전파의 강도가 대단히 미약하기 때문에 비, 구름의 영향, 건조물, 수목들의 영향을 받는 특성이 있어 좋은 화질을 얻기 위해서는 파라볼릭 안테나 등과 같이 양질의 수신 안테나가 필요하다.In the case of satellite broadcasting reception, when a satellite located on a stationary orbit above the equator relays the broadcast signal emitted from the terrestrial broadcasting station and re-launchs it to the ground, the satellite broadcasting reception antenna installed in each home receives it. It transmits to the satellite receiver connected to it so that viewers can watch the satellite broadcasting through the TV receiver, and it can get clear picture and perfect sound without a blind spot within a certain frequency range, so it is getting the spotlight from viewers day by day. In recent years, however, it is widely used in general homes, and such satellite broadcasting generally requires an appropriate receiver for receiving SHF (Super High Frequency) frequency signals in the range of 3 to 13 GHz, and existing VHF (Very High at 3 to 30 MHz). Frequency, strength of radio waves on the ground compared to Ultra High Frequency (UHF) radio waves of 30 MHz to 3 GHz To the very weak because of the rain, the effects of clouds, dry matter, the quality of the receiving antenna is needed, such as to have the characteristics of the affected trees to get a good picture parabolic antenna.

또한, 위성을 이용한 통신의 경우 마이크로파 주파수대의 고주파를 사용함으로써 전파의 직진성이 강하기 때문에 지향성이 큰 파라볼릭 안테나 등을 필요로 할 뿐만 아니라 위성 지구국이나 가정용과 같이 위치가 고정된 안테나와는 달리 이동체의 움직임에 따라 목표하는 위성의 위치를 추적하는 추적기능이 필요하다.In addition, in the case of communication using satellite, the radio wave has high linearity due to the use of high frequency in the microwave frequency band, and thus requires a highly directional parabolic antenna and the like, and unlike a fixed antenna such as a satellite earth station or a home, A tracking function is needed to track the position of the target satellite as the movement moves.

Satellite tracking antenna system and satellite tracking method. As shown in the drawing, a conventional antenna for receiving a satellite signal focuses a reflecting plate 310 for receiving a predetermined satellite signal in the direction of a target satellite and a satellite signal reflected from the reflecting plate 310 with an incoming waveguide 340.

상기한 바와 같이, 종래의 일실시예에 따른 위성신호 수신용 안테나는 반사되는 위성신호가 직접 수신되도록 안테나 전방에 수신기가 직접 설치되어 수신기의 고정을 위하여 고정부재를 필요로 할 뿐만 아니라 수신기의 돌출로 인하여 안테나의 크기가 불필요하게 커질 뿐만 아니라 수신기의 고정으로 인해 위성신호의 수신효율을 높이기 위한 수신기의 위치 보정이 어렵다는 문제점을 가지고 있었다. As described above, in the conventional antenna for receiving a satellite signal, a receiver is directly installed in front of the antenna so that the reflected satellite signal is directly received, and not only requires a fixing member for fixing the receiver but also protrudes from the receiver. Due to the unnecessarily large antenna size, the fixed position of the receiver has a problem that it is difficult to correct the position of the receiver to increase the reception efficiency of the satellite signal.

또한, 종래의 다른 실시예에 따른 위성신호 수신용 안테나도 안테나 전방에 설치되는 부반사판이 틸팅되어 회전하는 구성을 가지나, 부반사판이 위성신호의 수신효율을 유지 또는 증대시키기 위한 반사판으로부터의 위치 보정이 불가능하다는 문제점을 가지고 있었다.In addition, the antenna for receiving a satellite signal according to another exemplary embodiment also has a configuration in which the sub-reflection plate installed in front of the antenna is tilted and rotated, but the sub-reflection plate is corrected from the reflector to maintain or increase the reception efficiency of the satellite signal. I had the problem that this was impossible.

The sub reflection plate 130 is installed to be spaced apart from the inlet side of the wave guide 120, and re-reflects the satellite signal reflected from the reflection surface 111 of the main reflection plate 110 into the wave guide 120.

Can be located.

위치보정수단(140)은 서브반사판(130)에 의한 위성신호의 재반사율을 높이기 위하여 서브반사판(130)을 메인반사판(110)의 초점이 위치하는 메인반사판(110)의 중심축을 따라, 예컨대 도파관(120)이 메인반사판(110)의 중심에 초점을 향하도록 설치되는 경우 도파관(120)의 길이방향을 따라 이동시킴이 바람직하다.Position correcting means 140 is a sub-reflective plate 130 along the central axis of the main reflector 110, the focal point of the main reflector 110 is located, for example to increase the re-reflection of the satellite signal by the sub-reflective plate 130, for example When the 120 is installed so as to focus on the center of the main reflector 110, it is preferable to move along the longitudinal direction of the waveguide 120.

나사결합부재(141)는 도파관(120)의 본체(121) 외주면에 형성된 수나사부(121b)에 나사 결합됨으로써 회전하게 되는 경우 도파관(120)을 따라 이동한다.The screw coupling member 141 moves along the waveguide 120 when the screw coupling member 141 is rotated by being screwed to the male screw portion 121b formed on the outer circumferential surface of the body 121 of the waveguide 120.

이동부재(142)는 나사결합부재(141)에 의해 연결시 위성신호와의 간섭을 최소화하도록 다수의 연결바(144)에 의해 나사결합부재(141)에 연결되어 도파관(120)의 입구측에 위치하며, 서브반사판(130)이 설치됨으로써 나사결합부재(141)의 회전에 의해 서브반사판(130)과 함께 이동한다.The moving member 142 is connected to the screw coupling member 141 by a plurality of connecting bars 144 to minimize the interference with the satellite signal when connected by the screw coupling member 141 to the inlet side of the waveguide 120 In this case, the sub-reflection plate 130 is installed to move together with the sub-reflection plate 130 by the rotation of the screw coupling member 141.

고정볼트(143)는 나사결합부재(141)에 나사 결합되어 관통함으로써 회전에 의해 도파관(120)의 본체(121) 외주면을 가압하여 나사결합부재(141)가 원하는 위치에서 도파관(120)의 본체(121)에 고정되도록 한다.The fixing bolt 143 is screwed to the screw coupling member 141 to press the outer peripheral surface of the body 121 of the waveguide 120 by rotation, so that the screw coupling member 141 is the body of the waveguide 120 at the desired position It is fixed to (121).

한편, 서브반사판(130)은 메인반사판(110)으로부터 반사되는 위성신호를 도파관(120)으로 인입되도록 반사되기 위하여 볼록 또는 오목 형태 등과 같은 다양한 형태를 가질 수 있는데, 본 실시예에서는 도파관(120)을 향하여 돌출되는 원뿔 형태를 가지며, 이동부재(142)에 브라켓(142a)을 통해 고정되는 회전모터(131)의 축에 고정되는 회전축(132)이 상측에 형성됨으로써 회전모터(131)의 구동에 의해 회 전하도록 이동부재(142)에 설치되되, 메인반사판(110)의 중심축에 대하여 하나 이상의 특정 위치로 틸팅(Tilting)되도록 회전축(132)으로부터 틸팅된다.Meanwhile, the sub reflector 130 may have various shapes such as a convex or concave shape in order to reflect the satellite signal reflected from the main reflector 110 into the waveguide 120. It has a conical shape protruding toward, and the rotary shaft 132 fixed to the shaft of the rotary motor 131 fixed to the moving member 142 through the bracket 142a is formed on the upper side to drive the rotary motor 131. Is installed on the moving member 142 to rotate by, it is tilted from the rotating shaft 132 to be tilted (tilting) to one or more specific positions with respect to the central axis of the main reflector 110.

한편, 메인반사판(110)은 위성으로부터 송출되어 성층권과 대기층을 통과하여 출력이 저하된 위성신호를 증폭함과 아울러 수신된 위성신호의 잡신호 및 노이즈를 제거하는 LNB(Low Noise Block)(미도시)가 설치되는데, 바람직하게는 LNB가 도파관(120)이 설치된 반대면에 설치되어 도파관(120)과 수신홀(112)을 통해 위성신호가 LNB에 입사되도록 한다.On the other hand, the main reflector 110 is a low noise block (LNB) (not shown) for amplifying a satellite signal transmitted from the satellite to pass through the stratosphere and the atmospheric layer, the output signal is degraded and to remove the noise and noise of the received satellite signal Preferably, the LNB is installed on the opposite side where the waveguide 120 is installed so that the satellite signal is incident on the LNB through the waveguide 120 and the receiving hole 112.

이와 같은 구성을 가지는 본 발명에 따른 위성신호 수신장치(150)를 가지는 위성신호 수신 안테나(100)의 작동 및 작용을 본 발명에 따른 위성신호 수신방법과 함께 설명하기로 하겠다.The operation and operation of the satellite signal receiving antenna 100 having the satellite signal receiving apparatus 150 according to the present invention having such a configuration will be described together with the satellite signal receiving method according to the present invention.

본 발명에 따른 위성신호 수신방법은 크게, 도파관 설치단계와, 서브반사판 설치단계와, 수신최적화 단계를 포함한다.The satellite signal receiving method according to the present invention largely includes a waveguide installation step, a sub-reflection plate installation step, and a reception optimization step.

도파관 설치단계는 메인반사판(110)의 중심부에 위성신호의 전송을 위한 도파관(120)을 고정하여 설치하는 단계이다. 이 때, 도파관(120)은 메인반사판(110)의 중심에서 메인반사판(110)의 초점을 향하도록 수직되게 설치됨이 바람직하다.The waveguide installation step is to fix and install the waveguide 120 for the transmission of satellite signals in the center of the main reflector 110. In this case, the waveguide 120 is preferably installed vertically to face the focus of the main reflector 110 at the center of the main reflector 110.

서브반사판 설치단계는 메인반사판(110)으로부터 반사되는 위성신호를 도파관(120)으로 인입되도록 재반사시키는 서브반사판(130)을 위치보정수단(140)에 의해 메인반사판(110)과의 거리 조절이 가능하도록 도파관(120)의 입구측에 설치하는 단계이다. In the step of installing the sub-reflective plate, the position of the sub-reflective plate 130 for re-reflecting the satellite signal reflected from the main reflective plate 110 to be introduced into the waveguide 120 is adjusted by the position correction means 140 with the main reflective plate 110. It is a step of installing at the inlet side of the waveguide 120 to enable.

수신최적화 단계는 서브반사판(130)을 이동시켜서 도파관(120)으로 인입되는 위성신호가 최대가 되는 위치에 고정시키는 단계로서, 다양한 방법의 구현에 의해 서브반사판(130)을 이동시킬 수 있는데, 본 실시예에서는 위치보정수단(140), 즉 나사결합부재(141)의 회전량에 의해 도 5에 도시된 바와 같이, 서브반사판(130)이 메인반사판(110)의 중심축 상을 이동하여 위성신호의 수신 효율을 유지시키거나 향상시킬 수 있는 최적의 지점에 서브반사판(130)이 위치하도록 하며, 이 때, 고정볼트(144)의 조임에 의해 나사결합부재(141)가 도파관(120)의 본체(121)에 고정되도록 함으로써 서브반사판(130)을 고정시킨다. The reception optimization step is to fix the satellite reflecting to the waveguide 120 at the maximum position by moving the sub reflector 130. The sub reflector 130 may be moved by implementing various methods. In the embodiment, as shown in Figure 5 by the rotation amount of the position correction means 140, that is, the screw coupling member 141, the sub-reflection plate 130 is moved on the central axis of the main reflection plate 110, the satellite signal The sub-reflective plate 130 is positioned at an optimal point for maintaining or improving the reception efficiency of the sub-reflective plate 130. At this time, the screw coupling member 141 is tightened by the fixing bolt 144 to the main body of the waveguide 120. The sub-reflection plate 130 is fixed by being fixed to the 121.

수신최적화 단계는 일측에 길이조절관(121a)이 나사 결합됨으로써 조임과 풀림에 의해 길이가 조절되는 도파관(120)의 길이를 변경시킴으로써 서브반사판(130)의 이동과 함께 도파관(120)으로 인입되는 위성신호가 최대가 되도록 할 수 있다.The reception optimization step is introduced into the waveguide 120 with the movement of the sub-reflective plate 130 by changing the length of the waveguide 120 whose length is adjusted by tightening and loosening by coupling the length adjusting tube 121a to one side. The satellite signal can be maximized.

한편, 서브반사판(130)이 도파관(120)으로 인입되는 위성신호가 최대가 되는 위치는 메인반사판(110)의 곡률, 구조, 크기 등에 따라 각각 달라질 수 있으며, 메인반사판(110)이 파라볼릭 형태인 경우 그 초점에 위치함이 바람직하다.On the other hand, the position at which the sub-reflection plate 130 is the maximum satellite signal introduced into the waveguide 120 may vary depending on the curvature, structure, size, etc. of the main reflection plate 110, the main reflection plate 110 is parabolic It is preferable to be located at the focal point.

서브반사판(130)이 고정되면, 위성으로부터 송출되는 위성신호가 메인반사판(110)에 반사되어 초점에 위치하는 서브반사판(130)으로 입사되고, 입사된 위성신호는 서브반사판(130)에 재반사되어 도파관(120)으로 인입되어 수신홀(112)을 통해 LNB로 입사되어 IF(Intermediate Frequency) 신호로 변환 및 잡신호, 노이즈 등이 제거된 상태로 수신기로 수신되도록 한다. When the sub reflector 130 is fixed, the satellite signal transmitted from the satellite is reflected by the main reflector 110 and is incident on the sub reflector 130 positioned at the focal point, and the incident satellite signal is reflected back to the sub reflector 130. Then, the waveguide 120 enters the waveguide 120 and is incident to the LNB through the reception hole 112 to be converted into an IF (Intermediate Frequency) signal, and received by the receiver in a state in which miscellaneous signals and noise are removed.

이 때, 서브반사판(130)이 회전축(132)을 기준으로 틸팅되어 회전모터(131)에 의해 회전하게 됨으로써 서브반사판(130)이 상하 및 좌우 각 방향으로 틸팅되었 을 경우에 수신한 위성신호의 세기를 제어부에 의해 서로 비교하여 메인반사판(110)이 목표 위성에 대해 어느 방향으로 치우쳐져 있는지를 알 수 있게 되고, 이러한 위성신호의 차이값을 기준으로 위치보정신호를 생성하여 그에 대응하여 메인반사판(110)이 목표 위성을 지향하도록 회전 또는/및 이동하도록 함으로써 메인반사판(110)의 위성신호 수신 효율을 높인다. At this time, the sub-reflection plate 130 is tilted with respect to the rotation axis 132 and rotated by the rotation motor 131, so that the sub-reflection plate 130 is tilted in up, down, left, and right directions. By comparing the strengths with each other by the control unit, it is possible to know in which direction the main reflector 110 is biased with respect to the target satellite, and generate a position correction signal based on the difference value of the satellite signals to correspond to the main reflector. By allowing the 110 to rotate or / and move toward the target satellite, the satellite signal reception efficiency of the main reflector 110 is increased.

또한, 서브반사판(130)이 메인반사판(110) 전면에 위치하여 메인반사판(110)의 반사면(111)에 고정된 도파관(120)으로 위성신호를 인입시키는 구조를 가짐으로써 LNB 등의 구성 유닛이 메인반사판(110) 전면에 배치시킬 필요가 없음으로 인해 안테나의 규모를 줄임과 아울러 수신 효율을 높이는데 기여한다.In addition, the sub reflector 130 is located in front of the main reflector 110, and has a structure for introducing the satellite signal into the waveguide 120 fixed to the reflecting surface 111 of the main reflector 110, a component unit such as LNB Since it does not need to be disposed in front of the main reflector 110, it contributes to reducing the size of the antenna and increasing the reception efficiency.

그리고, 위치보정수단(140)에 의해 서브반사판(130)의 위치 가변이 가능함과 아울러 도파관(120)이 길이조절관(121a)에 의해 길이 조절이 가능함으로써 서로 다른 크기 또는 곡률을 가지는 어떠한 규격의 메인반사판이라도 용이하게 설치 및 적용할 수 있다.In addition, the position reflection of the sub-reflective plate 130 is possible by the position correction means 140 and the length of the waveguide 120 can be adjusted by the length adjusting tube 121a. Even the main reflector can be easily installed and applied.
