Description

Satellite antennas installed by the sun's shadow {.}

[Field of design]

The present invention relates to a satellite antenna.

More specifically, it relates to a satellite antenna installed by the shadow of the sun.

[Design background]

Satellite antennas are installed toward satellites and used as devices for transmitting and receiving satellites.

Satellite antennas are most commonly used as reflectors that reflect the transmitted and received radio waves. Among them, there are several types of satellite antennas, and those that absorb the received radio waves.

Other geomorphic satellite antennas are also used.

Among these various satellite antennas, the directional satellite antenna must adjust its angle toward the satellite.

Therefore, when installing a satellite antenna, a goniometer, compass, level meter, or spectrum is mobilized. These measuring devices are complicated in structure and cannot be permanently coupled to the antenna, and are detachable as necessary. Therefore, it is very difficult for the general consumer to install the satellite antenna directly.

In particular, the level meter and the spectrum can react only when the antenna angle reaches an approximate value, but only when the signal of the satellite starts to be received.

These problems are especially true when using digital signals, which are rapidly spreading in recent years.

Of course, if you use a non-directional satellite antenna or a satellite antenna with an electric angle adjustment device is not such inconvenience, but the structure is complicated, the economic burden can not be popular.

Therefore, the present inventors have a purpose to provide a satellite antenna that can be easily used by all consumers because the structure is very simple and responds even when the angle of the satellite antenna is far from the approximation.

So, we have developed a satellite antenna for installation using the shadow of the sun, and we have already applied for a patent for this antenna and are continuing to apply for improvement.

An object of the present invention is to provide a satellite antenna angle measuring device that can be installed without using a goniometer, a compass, a field strength measuring device.

Another object of the present invention is to simplify the above angle measuring device so that it can be permanently coupled to the satellite antenna.

Another object of the present invention is to provide a satellite antenna that can be easily installed by a general consumer.

Another object of the present invention is to provide a measuring device which responds even when the angle of the satellite antenna is not approximated toward the satellite, unlike the field strength measuring device.

The above main and other objects can all be achieved by the present invention described below.

Protrudes the support (2) toward the front from the lower portion (1) of the satellite antenna (O),

From the support (2) to the top of the satellite antenna (9) install a shadow generating device (4,5,6,7,8) composed of several layers in a straight line,

The first layer 4, which is the lowermost part of the shadow generating device 4,5,6,7,8, is elastic and flexible rubber band and is formed in a linear shape, and the lower part is near the protruding end of the support 2 ( 3) fixed to,

The second layer 5, which is the upper part thereof, is made of a material having elasticity and inflexibility and has a crisscross shape and a circle surrounding it.

The third layer 6, which is an upper portion thereof, is made of a non-elastic material and has a linear shape.

The fourth layer 7, which is the upper portion thereof, is a material having elasticity and inflexibility and has a crisscross shape.

The fifth layer 8, which is an upper portion thereof, is made of a non-elastic material and has a straight shape and is fixed to the upper center 9 of the satellite antenna.

The reason why the shadow generating devices 4, 5, 6, 7, and 8 are configured as follows is as follows.

First, the altitude of the sun varies greatly from season to season and from region to region, and the elevation angle of satellite antennas for satellites varies greatly from satellite to region.

That is, in some areas, the elevation angle to the satellite is so low that the crisscross part of the shadow generating device may be installed close to the angle table 11 so that shadows are generated in the lower part of the front of the antenna. The position of the ground shadow rises up, shortening the distance from the shadow generator to the shadow generated. The shorter this distance, the shorter the hourly movement distance of the shadow, which is a disadvantage in accuracy when adjusting the antenna angle.

Therefore, depending on the region, season, and the satellite to be directed, the shadow for the second layer or the fourth layer part of the shadow generating device 4, 5, 6, 7, or 8 may be selectively used for convenient use under various conditions. To do this.

Second, the shadow generating device (4, 5, 6, 7, 8) is not functioning if it is shaken by the wind during use or damaged by hitting other objects during transportation. Therefore, the first layer 4, which is the lowest of the shadow generating devices 4, 5, 6, 7, and 8, is installed by stretching the elastic band having a good elasticity and flexibility to have a proper contraction force. In this case, the shadow generating device (4,5,6,7,8) is not shaken by the wind due to the contracting force of the rubber band, and the rubber band is stretched to prevent damage by temporarily hitting another object.

(How to fix the shadow generator)

If the horn is an antenna of the type installed in front of the antenna, a device for supporting the horn is installed at the protruding end of the support 2, and a shadow generating device (4, 5) is provided at the upper part for supporting the horn. The first layer 4 of 6,7,8 is fixed, and the fifth layer 8 of the shadow generators 4,5,6,7,8 is fixed to the upper center 9 of the satellite antenna. .

If the horn is an antenna of the type installed behind the antenna, the device for supporting the horn is omitted on the support 2, and the shadow generating devices 4, 5, 6, 7, and 8 are provided.

The fifth layer 8 of the shadow generating device 4,5,6,7,8,

A hole 16 is made in the upper center 9 of the satellite antenna, and a ring 17 connecting the fifth layer 8 is inserted into the ball 16.

The ring 17 protruding to the opposite side of the insertion hole 16 is bent toward the upper antenna bottom,

The end of the ring 17 is composed of bolts 18, by tightening the nut 19 therein so that the ring cannot escape,

The shadow generating devices 4, 5, 6, 7, and 8 are capable of some movement from side to side and from side to side, but are configured to maintain a straight line as a whole by the contracting action of the elastic material part 4 of the first layer.

(Angle Chart Installation)

In front of the satellite antenna (O) 10, the shadow antennas (4,5,6,7,8) are satellite antennas generated by the date, time, coordinates of the Earth's earth, and the sun's shadow generated by the satellites directed by the satellite antenna. Install the angle table 11 to adjust the angle of the.

(Type of angle chart)

There are two types of angle tables.

First, the angle table by shadow trajectory

The angle table (7), which allows the satellite antenna angle to be adjusted by the shadow of the sun,

The fourth layer (7) and the second layer (5) of the shadow generating device (4,5,6,7,8) according to the satellites directed to the satellites, the area where the satellite antennas are installed, and the date on which the satellite antennas are installed. ) Shows the shadow trajectory to be formed by the part,

In the vicinity of the shadow orbit, write the satellite, region, and date.

The time to install the satellite antenna is represented by a plurality of visual lines that intersect the trajectory of the shadow, and characterized in that the configuration is described in the vicinity of the visual line.

(Shadow orbits have different shapes depending on the region and the satellites they are aiming at, so only the principle of shadow orbits and visual lines is explained.)

Second, angle table by shadow position calculation method

Angle table 11 for adjusting the satellite antenna angle by the shadow of the sun,

It is indicated by a plurality of horizontal lines 13 and a plurality of vertical lines 12, x1, x2, x3 in the vicinity of each line. . . . And also y1, y2, y3. . . Write your own symbols, such as.

In the plurality of longitudinal lines 12, portions of the first layer 4, the third layer 6, and the fifth layer 8 of the shadow generating devices 4, 5, 6, 7, and 8 may be changed according to time. The shadow to be formed is displayed at regular intervals to form a fan shape.

(Horizontal installation)

The bracket 14 at the rear of the satellite antenna O is provided with a leveler 15 for checking whether the left and right sides of the satellite antenna are horizontal.

Satellite antennas installed by the sun's shadow should not tilt the antenna to the left or to the right when viewed from the front. Since it is important to keep this level, it is to install the leveler 15.

(Installation of obstacle checking device)

In the upper center of the satellite antenna, an obstacle identification device 23 including a scale 21 and a scale 22 that is directed in the same direction as the elevation angle and azimuth angle of the antenna is installed.

This is difficult to accurately determine whether there is an obstacle in front of the antenna, especially in the case of the offset antenna is to solve the problem more difficult because the angle of elevation and reflector to hold the satellite is different.

The present invention is practiced as follows.

First, practical methods of the shadow generating apparatuses 4, 5, 6, 7, and 8 and the angle table 11 will be described.

According to the two angle tables 11 described above, there are two ways to adjust the angle.

First method (installation method by shadow orbit)

By the leveler 15 installed on the satellite antenna, the satellite antenna is leveled from side to side,

On the angle table installed in front of the satellite antenna, the shadow of the fourth layer 7 part or the second layer part 5 of the shadow generating devices 4, 5, 6, 7, 8 is lowered in the angle table. About what is made,

Find the satellites that will orient the antenna, the area where the antenna will be installed, and the shadow orbit corresponding to the date on which the antenna will be installed,

Find the line of sight that intersects the shadow orbit above and represents the time of installation of the antenna,

Adjust the direction of the antenna to match the shadow of the corresponding part of the shadow generator (4,5,6,7,8) to the intersection of the two lines above, and adjust the scale () and scale () of the obstacle identification device (). It will check whether there is an obstacle ahead.

Second method (installation method for shadow position calculation)

The horizontal level of the antenna is checked by the leveler 15 installed in the satellite antenna,

Satellite to be oriented to satellite antenna, place to install satellite antenna, date and time to install satellite antenna, second layer (5) or second of shadow generating device (4,5,6,7,8) The position of the shadow formed according to the fourth layer 7 and the angle table 11 is calculated by the x coordinate and the y coordinate,

By adjusting the direction of the antenna, at this calculated position (x, y), the center portion of the fourth layer 7 or the second layer 5 of the shadow generating devices 4, 5, 6, 7, and 8 To match the shadows of the centered calculations,

Through the scale 21 and the scale 22 of the obstacle checking device 20 to determine whether there is an obstacle in front.

(Shadow Position Calculation Method)

This section describes various ways to calculate the shadow position or to use the calculated result.

First, the operation program is installed on a separate computer to operate, but the data and results for the operation through the communication, such as the Internet

Second, how to input various calculation results in a separate computer and use them as needed

Third, how to make a lookup table based on various calculation results and use them as needed.

Fourth, the operation program is installed in the microprocessor built in the satellite broadcasting receiver used with the satellite antenna and operated

Fifth, a method of inputting various calculation results into a memory device built in a satellite broadcasting receiver used with a satellite antenna and using them as necessary.

Etc. Here, the fourth method is described in more detail as a representative example.

(When using a satellite broadcast receiver)

Satellite antennas do not function independently, but must be used with satellite receivers, etc.

The receiver already has an arithmetic unit that can install and operate a program that calculates the shadow position of the sun as described above, a receiver that can show the calculated results, and a keyboard (remote control) to perform the arithmetic.

Therefore, you only need to install the operation program on the above hardware.

In this calculation program, the names and positions of all existing satellites are inputted, and additional names and positions of satellites to be launched can be additionally inputted. Allows you to enter your name and latitude longitude.

Pre-set calendar and clock,

Enter the specifications of the shadow generator and angle table according to the model of the antenna.

When you want to install satellite antenna using such a calculation program,

Turn on the satellite receiver and receiver and enter the installation menu.

First, let the antenna choose the name of the satellite to be directed,

Second, choose a place to install the antenna,

Third, select the model number of the antenna.

According to this guidance, if you select the name of the satellite, the name of the area, and the model number of the antenna, the location of the shadow is output.

In some cases, there may be a difference of a few minutes between the time when the operation is performed and the time when the satellite antenna angle is adjusted. In this case, when outputting the position of the shadow as described above, there is a method of continuously outputting the position to move the shadow over time.

Therefore, the satellite antenna installed by the shadow of the sun of the present invention,

It can be installed without using a goniometer, compass, electric field strength measuring device, etc.

Unlike the field strength measuring device, it responds even when the angle of the satellite antenna is not approximated toward the satellite.

The angle measuring device for the above purpose can be greatly simplified to be permanently coupled to the satellite antenna,

Consumers can easily install satellite antennas.

Simple modifications or variations of the present invention can be readily made by those skilled in the art.

Especially in the case of satellite antennas not shown in the drawings,

As long as it has directivity, simple modifications or variations of the principle of adjusting the satellite antenna angle using the shadow of the sun can be easily carried out by one of ordinary skill in the art.

In particular, in the shadow generator and the angle table,

Modifications or changes within the principle range for adjusting the satellite antenna angle using the relationship between the position of the sun and the position of the satellite can be easily carried out by one of ordinary skill in the art.

All such variations or modifications fall within the scope of the present invention.
