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, the present invention relates to a satellite antenna angle measuring device and a satellite antenna installation method using the measuring device. More specifically, the present invention relates to a method of installing a directional satellite antenna using the shadow of the sun.

Background of the Invention

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

Satellite antennas are most commonly used as reflector plates to reflect the transmitted and received radio waves. Among them, there are some methods such as parabola and offset, and others are configured to absorb received radio waves.

Other undirected satellite antennas are also used.

Among these various antenna antennas, the directional satellite antenna must be precisely angled toward the satellite.

Therefore, when installing a satellite antenna, a goniometer, a compass, and an electric field strength measuring device are used. 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.

This problem is especially true when dealing with digital satellite 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.

Thus, the present inventors have a purpose to provide a measurement device and a satellite antenna coupled with the satellite antenna can be easily used by anyone, because the structure is very simple, even if the angle of the satellite antenna far beyond the approximation.

After that, he developed a measuring device that controls the angle of the satellite antenna using the shadow of the sun, or a satellite antenna combined with it, and has filed a patent application continuously related to it since the patent application was filed on Dec. 8, 1998, No. 98-53530. There is.

Previously patented inventions have the advantage that satellite antennas can be conveniently installed using the shadow of the sun, but it was inconvenient to check whether the antenna is horizontally or vertically when the antenna is fixed to the stand.

In other words, when the antenna is viewed from the front of the antenna with the azimuth adjusted, the stand must be installed so that the antenna does not tilt left and right, so the eyes should be vertically checked or a separate leveler should be used. This is the same in the case of the conventional satellite antenna that does not use the shadow, but more necessary in the case of the satellite antenna controlled by the shadow of the sun.

The most important object of the present invention is to provide a satellite antenna having a device for easily checking whether the stand is secured horizontally and vertically when installing a satellite antenna for adjusting the angle by the shadow of the sun.

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 greatly simplify the 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 with a device for checking whether the stand supporting the antenna is inclined when installing the satellite antenna.

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

Hereinafter, the contents of the present invention will be described in detail with reference to the accompanying drawings.

1, 3, 5, and 7 are front views schematically showing some of the various satellite antennas combined with the angle measuring device according to the present invention;

FIG. 2 is a side view of FIG. 1, FIG. 4 is a side view of FIG. 3, FIG. 6 is a side view of FIG. 5, and FIG. 8 is a side view of FIG.

The lower support 2 protrudes forward from the lower part of the satellite antenna 1.

The lower support 2 has a function of supporting the horn when the horn is installed in front of the satellite antenna (first, second, third, and fourth degrees), and separately when the horn is installed behind the satellite antenna. Install the lower support (2) of the 5th, 6th, 7th and 8th degrees.

From the end of the upper protruding lower support (2) to the top of the satellite antenna (3) is installed a shadow generating device (4-1) of the cross shape. That is, the lower part of the cross shape is fixed to the lower support (2), the upper part is fixed to the satellite antenna upper (3). The material of the shadow generating device 4 may be a structure and a material having a low degree of stretching, in spite of a change in the climate, but wires, chains, and chemical fibers may be used.

12 and 13 schematically show only two of the various angle tables to be installed in the satellite antenna.

It is installed on the satellite antenna surface 5, and the satellite antenna angle is read by the shadow of the generated sun.

In this angle table, the orbits of the shadows formed by the shadow generating device 4-1 according to the satellites to which the satellite antennas are directed, the area where the satellite antennas are to be installed, and the dates on which the satellite antennas are to be installed are represented by a plurality of lines 14.

The time to install the satellite antenna is configured to be represented by a plurality of visual lines 15 intersecting the trajectory 14 of the shadow.

The date corresponding to each track is described in the vicinity of each shadow track 14, and the time corresponding to each view line 15 is described in the vicinity of each view line 15.

The shadow trajectory 14 is formed according to the satellite facing the satellite antenna, the place where it is installed, the shape of the front surface of the antenna 5 on which the angle table 6 is installed, and the relationship between the shadow generating device 4-1 and the table 6, It forms various shapes.

For example, in most regions, the shadow trajectory 14 appears approximately in the horizontal direction, as shown in FIG. 12, and the shadow trajectory 14 is approximately vertical in the region near the equator, as shown in FIG. May be

However, since the visual line 15 is connected to portions corresponding to the same time of the shadow trajectory 14, the visual line 15 necessarily crosses the trajectory 14 of the shadow.
