Description

Solar altitude / azimuth angle measuring device using horizontal level / compass of smartphone {APPARATUS FOR MEASURING ELEVATION ANGLE / AZIMUTH OF THE SUN USING INCLINOMETER / COMPASS OF SMART PHONE}

The present invention relates to a solar altitude / azimuth measuring device, and more particularly to a solar altitude measuring device using a level gauge / compass of the smart phone.

In the elementary science experiment time, a process of checking the path of the sun according to the rotation of the earth is made by simply measuring the altitude and azimuth of the sun at the school playground. Here, the altitude of the sun means the angle the sun makes with the ground, and the azimuth of the sun is the compass angle

1 is a conceptual diagram showing the principle of a conventional solar altitude measurement method.

According to FIG. 1, only the rod 11, the seal 12 and the protractor 13 can measure the sun altitude easily enough.

Since the sun's altitude is the angle between the sun and the ground, the thread 12 is connected from the end of the shadow 20 generated by the rod 11 to the top of the rod 11 and extends to the end of the shadow 20. When the angle 30 of the seal 12 and the ground is measured using the protractor 13, the altitude of the sun is easily measured.

Likewise, elementary school students can conveniently angle.

However, it is often very inconvenient or inaccurate in measuring the altitude of the frame in this way.

For example, the rods are often not properly secured on the playground or outdoors. In addition, it should be fixed vertically perpendicular to the ground, even if using a protractor 13 is not easy to fix vertically.

And elementary school students carry a stick and often break it.

In addition, the thread should be fixed to the ground floor, if the shadow occurs outside the base plate fixed to the bar, it is not easy to fix the thread outside the base plate, and the accuracy is also inferior.

In addition, the thread 12 is pulled from the end of the rod 11 and extends to the end of the shadow 20, which also occurs when the rod 11 is moved or tilted. In this case, the bar 11 is bent, so that accurate altitude measurement cannot be performed.

In addition, the thread 12 is fixed to the bottom plate by a tack. Due to the wide tack of the tack, the end of the shadow and the part where the thread touches the ground do not exactly match.

In addition, when the floor is uneven, accurate measurement is difficult, and even when the ground is inclined, accurate measurement is not possible.

As such, although the measuring method of FIG. 1 has an advantage of being very simple, its accuracy and precision may not be guaranteed.

2a to 2c are experimental pictures showing a problem according to the conventional solar altitude measurement method.

Referring to FIG. 2A, there is a problem that the protractor cannot be accurately leveled because the ground is not flat.

In FIG. 2B, the shadow is cast low so that the thread must extend out of the measurement plate.

Referring to FIG. 2C, it is not possible to accurately distinguish the ends of the shadows, thereby indicating a problem in that the end points are not known.

On the other hand, the azimuth angle of the sun can be known by measuring the angle of the sun in the horizontal direction relative to the south-south direction, by measuring with a compass that the direction of the shadow changes with the passage of time, the azimuth angle can be known. However, since the shadow is formed to have a wide thickness or width according to the thickness or width of the bar 110, there is a problem that it is not easy to accurately read the direction of the shadow using a compass.

As described above, the solar altitude / azimuth measurement method using the existing simple tool is simple but has a problem in that the precision is poor.

Accordingly, the solar altitude measuring device of Korean Patent Publication Nos. 10-2009-0094640 and 10-2013-0029685 improves the precision of altitude / azimuth angle measurement of the sun by using a more complicated structure, but the structure is very complicated. There is a problem that the volume is large.

In addition, there is a problem that each elementary school students are not suitable for storing or maintaining a large number of experimental devices in the school for the experiment.

Figure 3 is a real example of the solar altitude / azimuth angle measuring device using a level gauge / compass of the smart phone according to an embodiment of the present invention.

Referring to FIG. 3, the solar altitude / azimuth measuring device 100 (hereinafter, referred to as “sun altitude / azimuth measuring device”) using the level / compass of the smart phone according to an embodiment of the present invention may be a smart phone 110. ), Cylindrical pipe 120, smart phone holder 130 and may be configured to include a transparent acrylic plate 140.

The solar altitude / azimuth measurement device 100 has the effect of easily measuring the altitude / azimuth angle of the sun by downloading and driving the solar altitude / azimuth measurement application from the smart phone 110. In particular, despite its convenience, it is very convenient because the measurement accuracy is high, records can be easily preserved and graphed.

In addition, by using the GPS module and the clock embedded in the smart phone 110 can accurately record the current coordinates and date and time at the time of measurement, it is very useful. If necessary, measurement results can be sent by e-mail or saved as an image.

Hereinafter, the detailed configuration will be described.

The smart phone 110 measures the altitude / azimuth angle of the sun using the sun altitude / azimuth angle measurement application of the smart phone 110. The solar altitude / azimuth measurement application consists of a level and a compass.

The smartphone 110 is adjusted to match the direction of the sun toward the sun is mounted on the smartphone holder 130, using a cylindrical pipe 120 that is integrally attached to the smartphone 110 (smartphone ( Adjust the direction of 110 to match the direction of the sun.

Here, a pair of cross scales 121 and 122 are provided in the cylindrical pipe 120, and the direction in which the respective shadows generated by the cross scales 121 and 122 overlap each other is the direction of the sun. Is the same direction as That is, using the shadow generated by the cylindrical pipe 120 to match the direction of the smartphone 110 to the direction of the sun.

Hereinafter, the detailed configuration will be described.

The smart phone 110 is installed and driven by the solar altitude / azimuth measurement application. Solar altitude / azimuth measurement applications are preferably implemented separately for use in solar altitude / azimuth measurement. If the application is not implemented separately, it is also possible to use it in place of the horizontal application or the compass application.

The cylindrical pipe 120 may be formed of a material such as plastic or steel as a long cylindrical shape, and may be configured to be detachably attached to one side of the smart phone 110.

Cylindrical pipe 120 is configured to be integral with the smart phone 110 in the state attached to the smart phone 110 is configured to maintain a direction consistent with the direction of the smart phone 110 at all times.

The inside of the cylindrical pipe 120 may be provided with a pair of cross scales (121, 122) superimposed on each other. At this time, the cross-shaped scales 121 and 122 may be replaced with shapes of other figures or symbols other than the cross, but the pair of scales are the same shape when the inside of the cylindrical pipe 120 is viewed from each other. It must be constructed so that it can be overlaid.

It will be described in more detail with reference to FIG.

4 is a conceptual diagram illustrating a cylindrical pipe and its use principle according to an embodiment of the present invention.

Referring to FIG. 4, the cylindrical pipe 120 includes a first cross scale 121 and a second cross scale 122 therein. The cylindrical pipe 120 is configured to find the direction of the sun, and is configured to adjust the direction of the smartphone 110 to match the light of the sun's rays.

When the direction of the cylindrical pipe 120 is adjusted to face the sun by adjusting the direction of the smartphone holder 130, sunlight passes through the inside of the cylindrical pipe 120.

At this time, the cross shadows 200 which are in contact with the inside of the circle are formed by the first cross scale 121 and the second cross scale 122 in the cylindrical pipe 120.

Here, in the case of slightly oblique and not exactly in the direction of sunlight in the direction of the cylindrical pipe 120, the shadow by the first cross-shaped scale 121 and the shadow by the second cross-shaped scale 122 are matched with each other Do not overlap. That is, some of the shadows of each other appear.

However, when the direction of the cylindrical pipe 120 and the direction of sunlight exactly match, the shadow 200 of the first cross-shaped scale 121 and the shadow 200 of the second cross-shaped scale 122 are accurately stacked to form one. . Thus, by looking at the shape of the shadow 200 can be indirectly confirmed that the cylindrical pipe 120, that is, the direction of the smart phone 110 that is integrally attached to it is pointing exactly to the direction of the sun.

The smartphone holder 130 is configured to manually adjust the direction of the smartphone 110 up, down, left and right so that the cylindrical pipe 120 attached to one side of the smartphone 110 faces the direction in which the sun is located. .

The smart phone holder 130 is manually adjusted by the direction of the smart phone 110 so that the shadows generated by the pair of cross scales 121 and 122 provided inside the cylindrical pipe 120 are superimposed on one another. The phone 110 is configured to be fixed / located.

The smartphone holder 130 is configured to be fixedly attached to the transparent acrylic plate 140 placed on the ground.

The transparent acrylic plate 140 is a plate having various shapes such as a square or a circle, and is configured to fix / support the smartphone holder 130 on the ground.

On the other hand, as described above, if the direction of the smart phone 110 exactly matches the direction of the sun, the sun altitude / azimuth angle measurement application pre-driven in the smart phone 110 measures the immediate solar altitude / azimuth angle to the touch screen And to display on the screen. Thus, the user can read and record the sun's altitude / azimuth.

First to measure the sun altitude, the sun altitude / azimuth measurement application is configured to measure and display the angle formed by the smart phone 110 and the horizontal plane by a level sensor provided in the smart phone 110. Here, a gyro sensor may be used as the level sensor. As the smart phone 110 is tilted from the horizontal plane, the gyro sensor built in the smart phone 110 senses the movement and the smart phone 110 calculates the tilt angle.

Thus, the solar altitude / azimuth measurement application calculates and displays the angle formed by the smart phone 110 with a horizontal plane, that is, the ground by the level function. In other words, the altitude of the sun is calculated and displayed.

Next, to measure the solar azimuth, the solar altitude / azimuth measurement application measures the orientation of the smartphone 110. The solar altitude / azimuth measurement application is configured to perform a compass function, and the compass function is configured to indirectly calculate the azimuth by coordinates calculated by a GPS module provided in the smartphone 110.

The solar altitude / azimuth measurement application is configured to calculate and display a bearing on which the smartphone 110 is headed by a compass implemented on the smartphone 110 and display it on the touch screen. This is because the orientation of the smartphone 110 indicates the orientation of the sun, it is possible to calculate the azimuth of the sun.

On the other hand, the altitude / azimuth angle of the sun calculated in the solar altitude / azimuth measurement application can be recorded directly on the paper, but it is preferable that the calculated value is stored by the solar altitude / azimuth angle measurement application.

In this case, when the value is stored by the user's touch input, the direction of the smart phone 110 may be changed due to the shaking of the smart phone 110. Therefore, the measured value may be stored according to the user's voice input. It is preferably configured to be stored in (not shown).

And if the solar altitude / azimuth measurement application stores the sun altitude / azimuth angle, it is desirable to store the measurement date and time together. This is because it is to study the change of altitude / azimuth angle of the sun according to the measurement date and time.

In addition, it is preferable to store the GPS coordinates of the measurement place or the latitude / longitude calculated by the GPS module built in the smart phone 110 together. This is because the altitude / azimuth angle of the sun also depends on the position on the earth.

And the solar altitude / azimuth measurement application is preferably configured to display the measurement date and time stored in the memory, GPS coordinates or latitude / longitude, the sun altitude / azimuth in a graph according to the measurement date and time. It is useful for reading and understanding the changes at a glance.

5 is a user interface screen of the solar altitude / azimuth measurement application according to an embodiment of the present invention.

Referring to FIG. 5, it can be seen that the sun altitude and sun azimuth and the measurement date and time displayed on the screen of the sun altitude / azimuth measurement application are displayed.

Figure 6a is a solar altitude / azimuth angle measurement table according to an embodiment of the present invention, Figure 6b is a solar altitude / azimuth angle graph according to an embodiment of the present invention.

As shown in Figure 6a, it can be seen that the right ascension / declination is calculated using the altitude / azimuth angle of the sun measured in units of 1 hour.

In addition, in FIG. 6B, it can be seen that the change in the altitude / azimuth angle of the sun in one hour unit is displayed in one graph.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. You will understand.
