Description

Satellite antenna combined with angle measuring device and its installation method

[Field of Invention]

The present invention relates to a satellite antenna.

More specifically, it relates to a satellite antenna combined with an angle measuring device.

In addition, the present invention relates to a method of installing a directional satellite antenna using the relationship between the positions of celestial bodies including the sun and the positions of satellites.

[Background of invention]

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

Satellite antennas are most commonly used in the form of a reflector reflecting the transmitted and received radio waves, and among these are divided into several types depending on the method of reflecting, there are also configured to absorb other received radio waves.

Other undirected satellite antennas are also used.

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

Therefore, when installing a satellite antenna, a goniometer, a compass, and an electric field strength measuring device are mobilized. These measuring devices are complicated in structure and cannot be permanently coupled to the antenna, and are detachable as necessary. It is very difficult for ordinary consumers to install satellite antennas directly.

In particular, the field strength measuring device responds when the antenna angle reaches an approximate value but starts to receive satellite signals.

The problem of difficulty in adjusting the satellite antenna angle is even more so when using digital signals that 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 an object of providing an angle measuring device and a satellite antenna coupled with it, which can be easily used by all consumers because the structure is very simple and the response of the satellite antenna is far beyond the approximation.

After that, he developed a measuring device that adjusts the angle of the satellite antenna using the shadow of the sun and a satellite antenna combined with it. Since the filing of the Patent No. 98-53530, it has been continuously applying for a related patent application.

Previously patented inventions have the advantage that satellite antennas can be conveniently installed using the shadow of the sun.

In general, even when the sun was observed with the naked eye on a cloudy day, it was still difficult to adjust the angle when no shadow was generated by the shadow generator 5 and at night when the sun was not observed.

Also, sometimes, when using a compass as in the past, there was no suitable place to keep it close. That is, it is difficult to use steel that affects the magnetic force of the compass in the part where the stand and satellite antenna are combined, and the compass is closely attached to the satellite antenna even if the satellite antenna itself, for example, the reflector is made of aluminum. There was no structure to do it.

In addition, the structure for close contact with the compass is linked to the change of the satellite antenna azimuth, but it will be more convenient if the level is always kept in spite of the change in the elevation angle. .

The inventors therefore seek to provide a satellite antenna that solves even the problems mentioned above.

The most important object of the present invention is to add a celestial orientation device (FIGS. 9-13) to a phase antenna composed of a solar shadow generating device 5, an angle table 7, and the like, so that not only the sun but also other astronomical positions The satellite antenna angle is adjusted using the relationship between the position of the satellite and the satellite.

(In this application, the description of the position of the celestial body, including the sun, does not mean its actual position, but the position observed on Earth.)

An object of the present invention is to provide a satellite antenna angle measuring device that can be measured without using a goniometer, a compass, an electric 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 used by a general consumer.

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

Another object of the present invention is to provide a satellite antenna with an obstacle identifying device made of a scale and a scale for identifying an obstacle within an angle to which the satellite antenna is directed.

Another object of the present invention is to provide a satellite antenna provided with a leveler to check the horizontal side of the antenna when adjusting the angle of the satellite antenna.

It is another object of the present invention to provide a satellite antenna that adds a circular shape to a crisscross shape shadowing device to distinguish the shadow position more easily.

Another object of the present invention is to provide a satellite antenna that can adjust the angle according to the position of the sun, even if the sun is observed with the naked eye even in cloudy weather in which no shadow of sunlight is generated.

Another object of the present invention is to provide a satellite antenna that can adjust the angle by using the relationship between the position of other heavenly bodies and satellites, even at night when the sun can not observe.

Another object of the present invention is to provide a satellite antenna that can be easily used in close contact with a separate compass having a straight side when trying to adjust the angle of the satellite antenna by the compass, such as not being able to observe all the above objects. I will.

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

The material is mainly metal or plastic,

The upper support 4 supporting the shadow generating device 5 avoids a particularly severe degree of expansion and contraction according to the climate change, and makes it easy to recover a straight line even if it is deformed using a flexible metal chain or chemical fiber.

The angle table (7), which allows the adjustment of the angle of the satellite antenna by the solar shadow, is divided into four categories.

First, the angle table by shadow trajectory

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.

(The angle table by the shadow trajectory is not shown separately because it forms the shadow trajectories of various shapes depending on the target satellite and the area where the satellite antenna is installed.)

Second, angle table by various kinds of shadow trajectories

It is characterized by combining different kinds of shadow orbits and visual lines with different shapes or colors for each of the satellites aimed at and the regions where satellite antennas are installed.

In other words, different kinds of angle tables should be used for each area where satellite antennas are installed for each of the satellites aimed at, and these multiple angle tables are integrated into one by varying the shape or color of each line.

9, 10, 11, 12, 13, 14 is a celestial orientation device, compass holder, obstacle identification device, leveler,

The celestial orientation device installs two posterior supports 10 from the top 9 of the satellite antenna toward the rear, and the two posterior supports 10 are celestial orientation devices of the celestial orientation device 10-1. 11)

In order for the celestial oriented support 11 to be interlocked with the change in the azimuth angle of the satellite antenna, but to always be horizontal despite the change in the elevation angle,

One side of the astronomical support base 11 is connected to the rear support 10 by a shaft 12, the lower portion of the weight 13 is installed,

In the upper center of the celestial support base 11, a thin celestial orientation 14 is installed in the vertical direction by the axis 15, so that it can be rotated 360 degrees about the axis 15,

The celestial azimuth angle chart 16 is displayed in the 1 o'clock direction, the 2 o'clock direction, the 3 o'clock direction, etc. along the rotating radius.

The compass holder 17 is installed at the edge of one side of the celestial support base 11 so as to be oriented at the same angle as the azimuth angle of the satellite antenna, so that the compass holder 17 has a straight side on the side. Characterized in that can be in close contact with a separate compass,

Since it is installed on the celestial oriented support base 11 which is always horizontal despite the elevation angle of the antenna, it is used as a method of rotating the azimuth angle of the antenna while keeping the compass in close contact with the compass guide. The celestial orientation device 10-1, reflector, etc. are made of a material that does not affect the operation of the compass.

Obstacle identification device 20 is composed of a scale 18 and the scale 19 at one upper portion of the rear support 10, it is easy to check whether there are obstacles such as buildings or trees in the adjusted angle range.

The leveler 8 is characterized in that the satellite antenna in the upper part of the satellite antenna 9 to check whether the left and right sides are horizontal. That is, when looking at the satellite antenna from the front of the satellite antenna, if the satellite antenna is inclined to the left and right, the satellite antenna does not function properly, which is more important in the case of the satellite antenna for adjusting the angle according to the present invention.

FIG. 15 is an angle table used for the celestial object 10-1.

On the upper part 9 of the satellite antenna, two rear supports 10 are installed toward the rear, and the two rear supports 10 support the celestial support base 11 of the astronomical device 10-1. In order to ensure that the celestial oriented pedestal 11 intersects with the change in the azimuth angle of the satellite antenna, but is always horizontal despite the change in the elevation angle,

One side of the astronomical support base 11 is connected to the rear support 10 by a shaft 12, the lower portion of the weight 13 is installed,

In the upper center of the celestial support base 11, a thin celestial orientation 14 is installed in the vertical direction by the axis 15, so that it can be rotated 360 degrees about the axis 15,

1 o'clock, 2 o'clock, and 3 o'clock along the rotating radius. . . . A celestial azimuth angle chart 16 is shown.

16 is an angle table 7 according to a calculation method.

It is indicated by a plurality of horizontal lines 14 and a plurality of vertical lines 15, and unique symbols are described in the vicinity of each line as x1, x2, x3 .... and y1, y2, y3 .... The distance between the horizontal lines 14 and the vertical lines 15 are determined in consideration of the allowable deviation when adjusting the angle of the satellite antenna.

Satellite antenna angle adjustment according to the present invention is practical as follows.

First, practical methods of the shadow generating device 5 and the angle table 7 will be described.

As described above, since the angle table 7 is divided into several types, there are several types of angle adjusting methods.

Method by the first and second angle table above (angle adjustment method by shadow trajectory)

By the leveler 8 installed on the upper part of the satellite antenna 9, the left and right sides of the satellite antenna are leveled,

On the angle table (7), which adjusts the satellite antenna angle by the shadow of sunlight installed on the front of the satellite antenna,

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

It is characterized by matching the shadow of the center of the shadow forming apparatus 5 to the intersection of the above two kinds of lines.

Method by the third angle table above (Angle control method by the calculation method)

While leveling the left and right sides of the satellite antenna by the leveler 8 installed on the satellite antenna upper part 9,

The position of the shadow formed according to the satellite to be directed to the satellite antenna, the place where the satellite antenna is to be installed, the date and time to install the satellite antenna, and the shadow generator (5) and the angle table (7) calculate with y coordinate,

It is characterized in that the shadow at the center of the shadow generating device 5 coincides with this calculated position (x, y).

The position (x, y) of the shadow of the shadow generating device 5 from above may be determined by the following equation.

(x, y) = F (k, f1 (g, h), f2 (d, t) f3 (c, m)

In the above formula, x means the x coordinate in the angle table (7), on the angle table (7), x1, x2, x3. . And y denotes the y coordinate in the angle table, and y1, y2, y3 on the angle table (7). . . . And so on,

The position of the shadow (x, y) by the shadow generator 5 is a function of k, f1 (g, h), f2 (d, t), f3 (c, m),

k is a variable determined by the position of the satellite to be directed,

f1 (g, h) is a function of the coordinates of the place where you want to install the antenna,

f2 (d, t) is a function of the date and time of installing the satellite antenna.

f3 (c, m) is a function determined by the angle table (7) and the shadow generating device (5).

Method by the fourth angle table (integrated angle table by shadow trajectory and angle table by calculation method)

The first angle table and the second angle table by the shadow trajectory are relatively simple to use, but they cannot be used in all regions of the world, and the third angle table has the disadvantage of being accompanied by microprocessor calculations. There is an advantage.

So, if you want to use satellite antenna for Mugunghwa satellite in Seoul area of Korea, you can adjust the angle of satellite antenna using shadow trajectory among satellite antennas with angle table integrated with angle table for Seoul area and Mugunghwa satellite. How to use it,

If you later decide to use it for another satellite, or move to another area to adjust the angle, you can adjust the angle by the calculation method.

Therefore, the fourth angle table is a method of selectively utilizing the combined angle table combined into one.

On the other hand, the shadow position operation described above is very complicated, so it may actually be processed as follows.

Satellite antennas do not function independently and must be used in conjunction with separate receivers (satellite broadcast receivers) or transceivers.

These separate devices already have the hardware to install the input device calculation program to input the above data, and the output device (TV, etc.) to show the calculated results.

Therefore, all you have to do is install the operation program containing the following data on the above hardware.

(Enter of satellite position)

In the above calculation program, the name and location of an existing satellite are inputted in advance, and in the case of an existing satellite, only the name of the satellite is selected (or, in the case of a newly launched satellite, the position of the satellite is 116 degrees east long). Type in)

(Enter region to install antenna)

In the region where the antenna is to be installed, the latitude and longitude are inputted in advance for each city, or the elevation angle and the azimuth angle are inputted in advance for each satellite for each satellite so that only the name of the city is selected.

(Enter year and time to install antenna)

The calculation program has a built-in calendar and clock.

(Enter the specification of shadow generator and angle table)

The satellite antenna according to the present invention may have various specifications, and the specifications of the shadow generating device 4-1 and the angle table 6 vary according to the specifications of the antenna. Depending on the type of 1) and the angle table (6), several satellite antenna model numbers are input in advance.

Therefore, when calculating the shadow position, selecting only the name of the satellite, the name of the region to be installed, and the model number of the satellite antenna outputs the position of the shadow.

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, it can be easily corrected by configuring to continuously output the position to move the shadow over time.

An example of such an operation is as follows.

For example, if you want to install a satellite antenna for the Mugunghwa satellite in Seoul, and the time is 13:30 and the model number of the antenna is "A2",

The horizontal ruler (8) checks the horizontality of the left and right antennas,

If you select "Mugunghwa satellite", "Seoul" and "A2" among the data inputted to the above operation unit, and execute the operation, the shadow position for it is output as "the intersection of x15 and y11".

The following describes a practical method of the celestial orientation device 10-1.

The astronomical orientation device 10-1 is practically used as follows to supplement the shortcomings of the shadow generation device 5 and the angle table 7 as follows.

While the horizontal antenna 8 installed on the upper part of the satellite antenna 9 adjusts the horizontal and horizontal direction of the satellite antenna,

Depending on the satellite orienting the satellite antenna, the area where the satellite antenna is to be installed, and the date and time to adjust the satellite antenna angle,

The azimuth angle (the azimuth angle observed to the naked eye on the earth) is calculated from the azimuth angle to which the satellite antenna is to be directed, and then rotates the celestial orientation 14 of the astronomical orientation device 10-1 toward the calculated direction. After releasing

Adjust the azimuth angle by rotating the azimuth angle of the satellite antenna until the angle directed by the celestial director 14 by the shadow of the celestial director 14 coincides with the azimuth angle to the sun. Adjust

or,

While the horizontal antenna 8 installed on the upper part of the satellite antenna 9 adjusts the horizontal and horizontal direction of the satellite antenna,

Depending on the satellite orienting the satellite antenna, the area where the satellite antenna is to be installed, and the date and time to adjust the satellite antenna angle,

The azimuth angle (azimuth angle observed with the naked eye on the earth) is calculated from the azimuth angle to which the satellite antenna is to be directed, and then rotates the celestial orientation 14 of the celestial orientation device 10-1 toward the calculated direction. After making it

The azimuth direction 14 adjusts the azimuth angle by rotating the azimuth angle of the satellite antenna until the angle directed by the astronomical object 14 is matched with the specific celestial body, and adjusts the elevation angle by a separate goniometer.

On the other hand, since the calculation of the azimuth angle (azimuth angle observed to the naked eye on the earth) from the satellite antenna described above is also very complicated, in practice, the same principle as the calculation method using the shadow generating device 5 and the angle table 7 is obtained. Can be processed by.

However, not all objects need to be dealt with for simplicity of operation, and only a few objects can be easily identified by the general public such as the moon and the North Star.

As the celestial orientation device 10-1 produces the angle table of FIG. 15 larger, the accuracy becomes higher, but it is difficult to manufacture the object as large as the solar shadow generating device 5 and the angle table 7,

After adjusting the elevation angle by a separate goniometer,

By the celestial orientation device to adjust the azimuth angle of the satellite antenna to a level that can be finely adjusted

Fine adjustment can be made by a separate electric field strength measuring device.

Next, a practical method of the compass holder 17 will be described.

When observation of all celestial bodies including the sun is not possible, a separate compass having a straight side on the side is in close contact with the compass holder 17, and then the satellite antenna azimuth is rotated while watching the compass instructions. That is, to adjust the azimuth angle to 190 degrees, the azimuth angle is adjusted in such a manner that the guide reaches the position corresponding to 170 degrees in the compass angle table, and the elevation angle is adjusted by a separate goniometer.

Next, a practical method of the obstacle checking apparatus 20 will be described.

After the satellite antenna angle adjustment as described above, by looking at the front through the scale 18 and the scale 19 of the obstacle identification device 20, to determine exactly what obstacles within the adjusted angle range is present.

Therefore, the satellite antenna combined with the angle measuring device of the present invention,

Angle measurement is more convenient without the use of a goniometer, compass, or field strength measurement device.The angle measurement device can be permanently coupled to the satellite antenna, and unlike the field strength measurement device, the angle of the satellite antenna Even when it is not approximated, it responds, and even obstacles within the angle of the satellite antenna are easily identified.

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 other than those shown in the drawings, as long as they have directivity, simple modifications or changes to the principle for controlling satellite antenna angles using the relationship between the positions of the celestial bodies and the positions of the satellites are not possible. It can be easily carried out by those skilled in the art.

In particular, for shadow generators, angle tables, and celestial objects,

Deformation or modification within the principle range of adjusting the satellite antenna angle by using the relationship between the position of the celestial body and the position of the satellite can be easily carried out by those skilled in the art.

Such modifications and variations are all within the scope of the present invention.
