1 is a block diagram of a mobile terminal having a celestial body information output function according to a preferred embodiment of the present invention.

Referring to Figure 1, it will be described in detail a preferred embodiment of a mobile terminal having a celestial information output function according to the present invention.

The mobile terminal according to an embodiment of the present invention, the GPS signal receiver 100 for receiving a GPS signal, the mobile communication module 110 for transmitting and receiving data with the mobile communication network, the direction recognition for recognizing the direction that the terminal is directed The module 120 includes an operation recognition module 130 that recognizes the operation of the terminal, a controller 140, a memory unit 150, and an input unit 160.

The GPS signal receiving unit 100 is a device for receiving a GPS signal to obtain information about the location of the mobile terminal, in addition to the Global Positioning System (GPS) operated by the United States, GLONASS (Global) operated by Russia Navigation Satellite System), a concept that includes GALILEO being developed by the European Union.

As a representative example of the direction recognition module 120, there is a geomagnetic sensor that is mainly used to detect the traveling direction of a vehicle or an aircraft vessel by sensing the magnetic field of the earth.

The principle of the geomagnetic sensor is that the drive coil is wound along a circular ring core, a ferromagnetic material, and the X-coil (coil wound in the X axis) and the Y-coil (wound in the Y axis) orthogonal to the center of the ring core. Jin coil) and Z-coil (coil wound on the Z axis). At this time, when the magnetic force line is generated in the ring core of the drive coil, the induced voltage obtained by combining the magnetic force and the geomagnetic generated in the ring core is measured through the X-coil, the Y-coil and the Z-coil, and the potential difference of the measured induced voltage The direction is detected by. Since the value measured by the geomagnetic sensor may change due to temperature change or other magnetic material in the surroundings, compensation may be necessary.

As described above, the geomagnetic sensor used in the present invention preferably uses three axes of X-coil, Y-coil and Z-coil, but may use two axes.

As a representative example of the motion recognition module 130, there is an acceleration sensor or a gyro sensor. Accelerometer detects dynamic forces such as acceleration, vibration and shock, and uses the application principle of inertial force, electric deformation and gyro.

Looking at the basic principle of the acceleration sensor, the acceleration is generated when the object moves, and the integration of the measured acceleration twice with respect to time is the moving distance. To measure front, back, top, bottom, left and right, three-axis acceleration sensor is needed.

Acceleration sensor can be classified into the following three according to the operation principle.

First, it is tropical. There is a gas mass inside the sensor, which is a heating element and heated air, but when there is an external movement, the gas mass moves. At this time, the sensor detects the sensor by changing the temperature emitted by the heating element.

Second is the Piezoresistive method. If the structure itself is inclined in accordance with the acceleration direction, the resistance value changes when the structure itself is inclined according to the acceleration direction, thereby changing the value of the current flowing through the structure and recognizing the change in current as an acceleration.

Third is the capacitive approach. This method uses mass inertia by putting a solid object that is a mass of mass inside the sensor. If no force is applied from the outside, the capacitance has a constant value, but if a force is applied in one direction, the internal solid moves in the opposite direction to the direction of the force and the internal capacitance changes in this process. The acceleration is measured by calculating the changed capacitance value.

The memory unit 150 stores a predetermined program for controlling the overall operation of the mobile terminal, and the data input and output when the overall operation of the mobile terminal is performed by the controller 140 and various data processed.

In addition, the astronomical information may include various information about a star or a constellation. Examples include images of stars or constellations, legends, animations, flashes, and videos.

Meanwhile, the celestial body information preferably includes celestial body position information composed of a specific coordinate system. For example, the celestial body information may include celestial position information obtained by matching a specific star or constellation with its equator coordinates.

As the coordinate system indicating the position of the celestial body, the horizontal coordinate system (horizon coordinates system), the equatorial coordinates (equatorial coordinates system), ecliptic coordinates system (ecliptic coordinates system), galactic coordinates (galactic coordinates system) are representative.

The horizontal coordinate system is a coordinate system in which the reference plane is the horizontal plane and the reference point is the north point, and the measuring method measures the azimuth along the horizontal plane from the north point clockwise (east) to the foot of the celestial body, and measures the azimuth angle from the foot of the celestial body to the celestial body + , Height towards the bottom.

The equatorial coordinate system is a coordinate system in which the reference plane is the equator plane and the reference point is the vernal equinox.The measuring method measures the right ascension in time units along the equator plane from the vernal equinox to the feet of the celestial body in the direction of the earth's revolution, Decline the Antarctic side with-.

The ecliptic coordinate system is a coordinate system in which the reference plane is the ecliptic plane and the reference point is the vernal equinox, and the measuring method measures angles along the ecliptic plane from the vernal equinox to the feet of the celestial body in the direction of the earth's revolution, and measures northward from the celestial feet to the north +, south By-measure the value by the latitude.

The galactic coordinate system is a coordinate system that is the galaxy (galactic equatorial) and the reference point is the galactic center (Sagittarius), and the measuring method measures the angle of the silver mirror from the center of the galaxy to the east along the galaxy and measures the galaxy from the feet of the celestial body to the celestial body. The North Pole of + and South-Negative value.

On the other hand, each coordinate system can be converted to another coordinate system. For example, the horizon coordinate system can be converted to the equator coordinate system, the equatorial coordinate system can be converted to the horizon coordinate system.

Since the coordinate calculation method of the celestial position by each coordinate system and the conversion to other coordinate systems are well known, detailed description thereof will be omitted.

The input unit 160 is a device for receiving various information or commands from a user, such as a keypad or a touch screen having various keys.

The controller 140 manages the overall operations of the mobile terminal. In particular, the controller 140 controls the GPS signal receiver 100, the mobile communication module 110, the direction recognition module 120, the motion recognition module 130, the memory unit 150, and the input unit 160.

It is preferable to include the information processing unit 147 for searching and outputting the celestial body information corresponding to the memory unit 150.

The information acquisition unit 145 uses the GPS signal received through the GPS signal receiving unit 100 or the mobile communication base station system parameter received through the mobile communication module 110 to obtain location information of the mobile terminal. Acquire and output. As a representative example of the location information, there is latitude / longitude information.

The information acquisition unit 145 may receive location information directly from a user through the input unit 160. For example, the location of the terminal is Seoul, South Korea, but if the user wants to be provided with the sky constellation seen in Washington, USA, the user can directly enter Washington, USA.

The information obtaining unit 145 obtains time information by using a GPS signal received through the GPS signal receiving unit 100 or a mobile communication base station system parameter received through the mobile communication module 110. Output

On the other hand, the information acquisition unit 145, like the location information, may receive the location information directly from the user via the input unit 160. For example, the current time is 9:00 pm on December 12, 2005, but the user can enter 10:00 pm on January 1, 2006.

In addition, the information acquisition unit 145, by using the direction recognition module 120 and the motion recognition module 130, it is preferable to obtain the direction information by measuring the amount of change of orientation and altitude.

On the other hand, it is preferable that the said direction information contains the information about all directions and altitudes of three dimensions. The reason why the direction information includes all directions and altitude information in three dimensions is not limited to the sky that can be observed from the user's or the terminal's current location only by the user's naked eye. For example, even if the direction of the terminal indicates the other side of the earth to allow the user to observe the sky on the other side of the earth through the terminal.

Hereinafter, a case in which the direction recognition module 120 is a geomagnetic sensor and the motion recognition module 130 is an acceleration sensor will be described.

For example, the information acquisition unit 145 may use the geomagnetic value received from the direction recognition module 120 and the acceleration value received from the motion recognition module 130 to determine the azimuth and altitude of the terminal. Obtains and outputs direction information to be included.

Here, azimuth and altitude are concepts that encompass all of the terms used in each coordinate system for indicating the position of the celestial body. For example, in the equatorial coordinate system, the orientation becomes right ascension, and the altitude is declination.

The information acquisition unit 145 may measure the azimuth and altitude of the terminal using only the geomagnetism value received from the geomagnetic sensor, but from the acceleration sensor to improve the acquisition speed and accuracy of the direction information. It is preferable to simultaneously use the received acceleration value.

In addition, the information acquisition unit 145 may directly receive specific direction information, including azimuth and altitude, from the user through the input unit 160.

The information processor 147 searches for and outputs celestial information corresponding to position information, time information, and direction information received from the information acquisition unit 145.

In addition, the information processor 147 calculates a horizontal coordinate corresponding to the received position information, direction information, and time information, and converts the calculated horizontal coordinate into a coordinate system of celestial information stored in the memory unit 150. The memory unit 150 may be searched for using the converted coordinate system. By this operation, celestial information located at the horizontal coordinates or the converted coordinates can be output.

For example, when the coordinate system of the celestial information stored in the memory unit 150 is the equator coordinate system, the information processing unit 147 converts the calculated horizon coordinates to the equator coordinates.

Meanwhile, the output method of the astronomical information may vary. For example, an image of a star or a constellation stored in the memory unit 150 may be displayed, or related text information may be displayed or output through voice. It can also be output in the form of video, animation, flash, etc.

In addition, the range of the celestial information to be output may be predetermined or set by the user. That is, the information processing unit 147 outputs celestial information within a predetermined area including the horizon coordinates or the converted coordinates. In this case, the predetermined area may be predetermined or its range may be adjusted by the user. That is, the user may enlarge or reduce the area in a specific direction that the terminal is facing, such as a zoom-in / zoom-out function of the camera.

2 is a flowchart of a celestial body information output method according to a preferred embodiment of the present invention.

Referring to Figure 2, a preferred embodiment of the celestial body information output method according to the present invention will be described in detail.

First, when entering the astronomical information output function provided by the mobile terminal [S200], the location information of the terminal, direction information including the orientation and altitude directed by the terminal, and time information are obtained [S210].

The location information may be obtained by receiving a GPS signal, or may be obtained by using a mobile communication base station system parameter received through a mobile communication network. An example of the location information is latitude / longitude information.

The direction information is information including the azimuth and the altitude to which the terminal is directed. That is, it includes the orientation and altitude of the celestial position to which the reference plane or reference point of the terminal is directed.

Here, azimuth and altitude are concepts that encompass all of the terms expressed differently for each coordinate system for indicating the position of the heavenly bodies. That is, in a horizontal coordinate system, azimuth represents azimuth and altitude represent altitude, respectively. In the equatorial coordinate system, the azimuth indicates the right ascension and the altitude indicates the declination, respectively.

In addition, the direction information is preferably performed by measuring the change in the orientation and altitude using the geomagnetic sensor and the acceleration sensor. The use of both the geomagnetic sensor and the acceleration sensor to obtain the direction information is to increase the processing speed and accuracy.

The time information may be obtained by receiving a GPS signal, or may be obtained by using a mobile communication base station system parameter received through a mobile communication network. The time information is a concept including a date and time.

Meanwhile, at least one or more of the location information, direction information, and time information may be directly input by the user. In particular, in order to be provided with celestial information of the sky viewed in a specific direction from a location different from the user's location and a current time, the user needs to directly input necessary information.

In addition, horizontal coordinates corresponding to the obtained position information, direction information, and time information are obtained [S220]. Then, the obtained horizon coordinates are converted into equator coordinates [S230], and astronomical information located at the converted equator coordinates is output [S240].

In the coordinate conversion process [S230], it is assumed that the celestial information stored in the database is composed of an equator coordinate system. When the celestial information stored in the database is composed of another coordinate system, the coordinate transformation process should be converted to the coordinate system. That is, in the coordinate conversion process [S230], the coordinates obtained by using the obtained position information, direction information, and time information are converted into coordinates of celestial information stored in a database, and the database is searched using the converted coordinates. This is a process for reading celestial information corresponding to the coordinates.

In the celestial body information output process [S240], it is preferable to output celestial body information within a predetermined region including the converted equator coordinates, and the predetermined region is a zoom-in used when photographing by a camera. Like the -in / zoom-out function, the range is adjustable by the user.

In addition, the form of the astronomical information output may vary as mentioned above. That is, it may be output as image information such as an image, a video, or the like, and a star, a constellation name, or a legend may be output as audio information.

FIG. 3C illustrates a screen displaying a constellation above the constellation displayed in FIG. 3B with the altitude of the mobile terminal facing upward in the state of FIG. 3B. FIG. 3D illustrates a screen displaying a constellation to the east from the constellation displayed in FIG. 3B with the mobile terminal facing in the state of FIG. 3B to the east.

In addition, it is determined whether at least one or more of the position information, the direction information, and the time information change [S250], and according to the change, the process [S210, S220, S230, S240] is repeated to update and output the celestial information. do.

In the determination process [S250] regarding the change of the position information, the direction information, and the time information, the change can be set in various ranges.

For example, since the change in the celestial information according to the change in the position of the terminal may not be very large, the change in the celestial information according to the change in the position information may not be considered, and even if the degree of change in the position of the terminal is very significant, You will need to set it to update the celestial information.

In addition, the change of time information for the astronomical information update output may be set by the user every 30 minutes or every 1 hour.

Since the change in the celestial information according to the change in the direction of the terminal is greater than the change in the celestial information according to the positional information or the time information, the celestial information is set to be updated and output even if there is a minute change in direction. Could be.

In addition, it is determined whether the celestial body information output function is to be terminated (S260). As a representative example of the case where the astronomical information output function is to be terminated, a function termination command may be received by a user.
