Referring to FIG. 1, a satellite signal transmission system 10 according to an embodiment may include a satellite 100, a flat antenna 200, an IP allocator 300, and a terminal 400.

The satellite 100 may transmit various information to the earth, for example, by orbiting a predetermined orbit around the earth.

The satellite 100 may be variously classified into communication satellite, broadcasting satellite, meteorological satellite, scientific satellite, navigation satellite, earth observation satellite, technology development satellite, and military satellite depending on the purpose of use.

Various information observed in the satellite 100 can be transmitted to the earth as a radio wave. Hereinafter, a satellite signal, which is a video signal related to a satellite broadcast, will be described as an example.

The satellite signal may be received by a flat antenna (200).

The planar antenna 200 is an antenna having an open surface for receiving a satellite signal. The planar antenna 200 has an advantage that an antenna gain can be increased as compared with a parabola antenna, and the antenna can be less subject to installation.

2 to 5, the planar antenna 200 may include a signal receiving unit 210, a signal processing unit 220, and a signal tracking unit 230.

In particular, referring to FIG. 3, the planar antenna 200 may be provided in a rectangular parallelepiped shape, for example.

However, the shape of the flat antenna 200 is not limited thereto, and any structure can be used as long as it can efficiently receive satellite signals. For example, the shape of the flat antenna 200 may vary depending on the area where the flat antenna 200 is installed or the antenna gain required for the flat antenna 200.

In addition, the flat antenna 200 may be fixed or not fixed at a position where the antenna installation is required. For example, when the flat antenna 200 is mounted on a moving means such as an automobile or a train, the place where the flat antenna 200 is placed can be changed according to the movement of the moving means.

The signal receiving unit 210 may be disposed on one side of the flat antenna 200, particularly on the front side thereof, to directly receive satellite signals from the satellite 100.

Although not shown in detail, a waveguide that can separate and guide the satellite signal received from the satellite 10 may be formed in the signal receiving unit 210. In other words, the satellite signal received from the front of the signal receiving unit 210 can be transmitted to the inner space of the signal receiving unit 210 through the waveguide.

Referring to FIG. 4, a signal processing unit 220 may be disposed on the back surface of the flat antenna 200.

The signal processing unit 220 may include, for example, a signal amplification element 222, a frequency conversion element 224, and an IP conversion element 226.

The signal amplifying element 222 may amplify a satellite signal because the satellite signal received from the signal receiving unit 210 is very weak.

The frequency conversion element 224 transforms the frequency of the satellite signal amplified by the signal amplification element 222 and can convert the frequency to a standardized intermediate frequency. The intermediate frequency is typically normalized from 950 MHz to 2,150 MHz, so that there is device compatibility.

The signal amplifying element 222 and the frequency converting element 224 may be implemented by, for example, a low noise block down converter (LNB). Although not shown in detail, a frequency mixer ) And a local oscillator (LO).

The IP conversion element 226 may be implemented, for example, as an IP (Internet Protocol) server.

The signal amplification element 222 and the satellite signal amplified and frequency converted in the frequency conversion element 224 described above can be transmitted to the IP conversion element 226. [

The IP conversion element 226 can convert the satellite signal into IP data corresponding to the transmission using the IP, for example, demodulate and convert the received satellite signal into IP data. More specifically, the IP conversion element 226 can convert the demodulated RF video signal from either the DVB-S layer or the DVB-S2 layer to an IP (Internet Protocol) transport layer.

Although not shown in detail, a plurality of guide elements may be provided in the signal processing unit 220 for signal transmission between the signal receiving unit 210 and the signal processing unit 220.

The plurality of guiding elements may include a first guiding element and a second guiding element.

The first guiding element may guide the received satellite signal to the signal amplifying element 222 and the frequency converting element 224 and the second guiding element may direct the signal amplifying element 222 and frequency It is possible to guide the satellite signal that has been amplified and converted from the conversion element 224 to the IP conversion element 226. [

Furthermore, it is of course possible to further include a third guiding element capable of directing the satellite signal received by the signal receiving section 210 to the plurality of guiding elements directly to the IP converting element 226.

In this way, the signal processing unit 220 can be mounted on the back surface of the flat antenna 200, thereby preventing the signal processing unit 220 from being exposed to the outside, and the aesthetic appearance can be improved.

In addition, since the signal receiving unit 210 and the signal processing unit 220 are integrally provided, the flat antenna 200 can be made thinner and can have a compact structure, It is possible to prevent the loss of the satellite signal and further improve the antenna gain.

For example, when the signal receiving unit 210 and the signal processing unit 220 are separately provided, the signal receiving unit 210 and the signal processing unit 220 must receive a signal by wire or wireless, And it may be limited by space when the flat antenna 200 is installed.

The signal processing unit 220 may include a plurality of terminals, and the plurality of terminals may transmit signals processed by the signal processing unit 220 to the various terminals 400.

The plurality of terminals may include a first signal output terminal P1, a second signal output terminal P2, and a third signal output terminal P3.

The first signal output terminal P1 may output a satellite signal, that is, a first signal amplified by the signal amplification element 222 and the frequency conversion element 224 and having a frequency converted, to the first terminal.

The first terminal may be a communication device 232, such as a set top box, for example, and may be a satellite amplified and frequency converted from the signal amplification component 222 and the frequency conversion component 224, A signal may be output to the display device 234, such as a TV, via the communication device 232.

The communication device 232 and the display device 234 may be provided in the signal tracing unit 230 so that the first signal output terminal P1 transmits a signal from the signal processing unit 220 to the signal tracing unit 230 Can be output.

Also, the first signal output terminal P1 may be referred to as legacy in that it is connected to an existing terminal, for example, the set-top box 420. [

The second signal output terminal P2 is an IP data output terminal. The first signal transmitted to the IP conversion element 226 is an IP data signal converted into IP data corresponding to the transmission using the IP, that is, the second signal To the second terminal.

Here, the second terminal may be an IP allocator 300, for example a router, and the IP data converted by the IP conversion element 226 may be transmitted to the TV, And may be transmitted to various terminals 400 provided in a network such as a device.

The third signal output terminal P3 can output the IP data signal converted by the IP conversion element 226 to the third terminal. Here, the signals output through the second signal output terminal P2 and the third signal output terminal P3 may be the same or different from each other. The third terminal may be a different terminal than the second terminal. For example, if the second terminal is an IP allocator disposed indoors, the third terminal may be an IP allocator disposed outdoors.

The third signal output terminal P3 is additionally provided to the flat antenna 200 to transmit IP data to the third terminal, which is additionally provided, and may be referred to as PoE (Power of Ethernet).

Although a plurality of terminals are described herein as including the first signal output terminal P1, the second signal output terminal P2, and the third signal output terminal P3, the present invention is not limited thereto, The types of equipment to be connected can be variously configured.

Since the signal processing unit 220 has a plurality of terminals, the flat antenna 200 can be compatible with the existing terminal, and the signal of the flat antenna 200 can be transmitted to various terminals.

The plurality of terminals may include a power supply terminal.

The power supply terminal may be provided as a separate terminal, or the first signal output terminal, the second signal output terminal, or the third signal output terminal may function as a power supply terminal.

The power supply terminal may supply power to the IP allocator 300 or the terminal 400. The IP device 300 connected to the communication device 232 and the display device 234 of the signal tracing unit 230 connected to the first signal output terminal P1 and the second signal output terminal P2, And the terminal 400. [0064] Therefore, it is possible to independently supply power to various terminals connected to the flat antenna 200, so that the terminal can be operated without connecting another power line to the terminal.

Furthermore, the plurality of terminals can contribute to tracking the satellite signal from the satellite 100 and efficiently controlling the direction to which the signal receiving unit 210 is directed. This is because the third signal output terminal P3 is added to the signal processing unit 220 and the existing first signal output terminal P1 is still removed without being removed and will be described in more detail below.

The signal tracing unit 230 may control a direction of the signal receiving unit 210 based on a signal transmitted from the signal processing unit 220.

For example, the signal tracing unit 230 may include a communication device 232, a display device 234, and a signal tracking element 236.

The first signal output through the first signal output terminal P1 may be received in the communication device 232. [ In this case, the first signal may be a signal obtained by amplifying and frequency-transforming the satellite signal received by the signal receiving unit 210.

As described above, since the first signal output terminal P1 is connected to the communication device 232, the first signal can be output from the display device 234, such as a TV connected to the communication device 232. [

The display device 234 may also be connected to the communication device 232 to output the first signal received by the communication device 232 as a video signal.

At this time, whether the satellite signal is tracked from the video signal output from the display device 234 can be determined. For example, it is possible to determine whether the signal receiving unit 210 receives an optimal satellite signal from the video signal output from the display device 234. [

Specifically, referring to FIG. 5, the signal tracking element 236 may be activated if tracking of the satellite signal is required to receive an optimal satellite signal.

The signal tracking component 236 is substantially a component that adjusts the direction that the signal receiver 210 is directed to, and may include, for example, an elevation angle, azimuth, and skew ). ≪ / RTI >

The azimuth angle indicates an angle at which the front of the signal receiving unit 210 is viewed toward the satellite 100. The azimuth angle indicates the direction of the satellite 100 based on the front of the signal receiving unit 210, And the skew represents an angle formed by the polarization wave received through the front face of the signal receiving unit 210 and the ground.

Specifically, the signal tracking element 236 may be manually implemented by a user, or may be implemented automatically by mounting a driver (not shown) on the flat antenna 200.

For example, the driver may be provided with a plurality of motors connected to the lower end of the flat antenna 200. The elevator angle of the flat antenna 200 may be adjusted by the driver in the range of 15 to 90 degrees, Can be automatically adjusted in the range of 60 to 60 degrees.

However, when the planar antenna 200 is mounted on the moving means, for example, the position of the flat antenna 200 from the current position of the flat antenna 200 It also needs to be considered. To this end, a GPS can be mounted on the signal tracking element 236.

Since the plurality of terminals 400 are connected to the flat antenna 200, the signal receiving unit 210 can receive the satellite signals of the specific satellites (for example, 100, and the front of the signal receiving unit 210 may be directed toward the searched satellite 100.

If the user selects the particular satellite 100, the position of the specific satellite 100 is searched from the plurality of terminals 400 and then the front of the signal receiving unit 210 is directed toward the specific satellite 100 can do.

In addition, in order to track the satellite signal, various terminals 400 connected to the IP allocator 300, as well as the communication device 232 and the display device 234 of the signal tracing unit 230, may also be associated.

For example, the signal tracking element 236 of the signal tracing unit 230 can be operated by referring to information obtained from the various terminals 400 connected to the IP allocator 300.

In this way, the signal tracking unit 230 can track the optimal satellite signal through various methods and can control the direction to which the signal receiving unit 210 is directed.

5, when a signal tracking element 236 is provided below the flat antenna 200, a signal amplifying element 234 for amplifying the satellite signal received by the signal receiving unit 210 is provided on the back surface of the flat antenna 200, A frequency conversion element 224 for converting the frequency of the amplified satellite signal and a frequency conversion element 224 connected to a support provided at the bottom of the signal tracking element 236, An IP conversion element 226 for converting the converted satellite signal into the IP data, and an IP allocator 300 for assigning an IP address to the terminal 400.

5, the IP converter 226 and the IP allocator 300 may be mounted on the back surface of the flat antenna 200 like the signal amplification element 222 and the frequency conversion element 224, Do.

The flat antenna 200 including the signal receiving unit 210, the signal processing unit 220 and the signal tracing unit 230 may be connected to the IP allocator 300.

The IP allocator 300 is a hardware and software device that connects two or more networks and enables communication from one communication network to another communication network. The IP allocator 300 may have a function of converting an address between the networks or converting the protocol to an appropriate one.

Specifically, the IP allocator 300 may forward the satellite signal converted by the IP conversion element 226 to the assigned IP address, and output the satellite signal from the terminal 400.

Herein, although the IP allocator 300 has been described as a separate component of the terminal 400, it is natural that the IP allocator 300 may be included in the terminal 400. [

The signal output from the signal processing unit 220 is transmitted to the various terminals 400 through the IP allocator 300 such as a mobile device, a set top box, a TV, various sensors, .

6, the signal processing unit 220 of the flat antenna 200 is provided with a terminal capable of outputting a plurality of IP signals, such as a second signal output terminal P2 or a third signal output terminal P3 The IP allocator 300 provided in the indoor space, and the IP allocator 300 provided in the outdoor space.

Here, the IP allocator 300 may be installed not only in the room but also on the back surface of the flat antenna 200 and outdoors. In other words, the IP allocator 300 can be disposed both indoors and outdoors, and the flat antenna 200 is provided with a signal receiving unit 210, a signal processing unit 220, and a signal tracking unit 230 as well as an IP allocator 300 may be integrally provided.

For example, when the IP allocator 300 is embedded in the flat antenna 200, the signal processing unit 220 of the flat antenna 200 includes a signal amplification element, a frequency conversion element, an IP conversion element, and an IP allocation element can do.

In this case, the IP allocation element can transmit and receive signals wirelessly with the flat antenna 200 or the terminal 400.

Furthermore, the terminal of the signal processing unit 220 may be connected to a terminal 400 such as an IP camera disposed outside the room, and may receive a signal from the IP camera.

However, the terminal 400 disposed outside the room is not limited to the IP camera, and may be provided with various sensors such as a humidity sensor and an air purity sensor, and the information obtained from the IP camera or the sensor may be transmitted to the other terminal 400 or the signal And may be usefully transmitted to the tracking unit 230.

Further, as described above, the plurality of terminals can supply a network or power to various terminals such as an IP camera or various sensors.
