And will be provided with the bearing information.

In addition, the multi-function battery pack according to an embodiment of the present invention further includes an exercise amount calculating unit for calculating an exercise amount by calculating and processing azimuth information detected by the geomagnetic sensor, thereby providing calorie consumption information according to the exercise amount to a terminal user. Will be.

As described above, when the multi-function battery pack includes a storage unit for storing map information, the battery capacity may be limited and the battery design may be complicated. Therefore, the battery pack simply receives a GPS signal and outputs current location information. A GPS receiver;

A geomagnetic sensor for detecting geomagnetic and outputting current bearing information;

An absolute bearing processor for correcting the bearing information detected by the geomagnetic sensor with the current position information to calculate an absolute bearing angle;

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a multifunction battery pack according to an embodiment of the present invention.

Referring to FIG. 1, a battery pack 100 according to an exemplary embodiment of the present invention basically includes a plurality of battery cells (not shown) as a power supply source for supplying operating power to the mobile phone main body 200. It has a mechanical configuration that can be combined with the main body 200.

Multifunction battery pack 100 according to an embodiment of the present invention basically includes a GPS receiver 110 and a geomagnetic sensor 120 to provide a location-based service (LBS). The GPS receiver 110 receives the GPS signal and outputs the current position information, and the geomagnetic sensor 120 detects the geomagnetism and outputs the current orientation information.

The geomagnetic sensor 120, which is an azimuth detection means, may use various geomagnetic sensors in addition to the flux gate type magnetic sensor. One of the flux gate type magnetic sensors is described in Japanese Patent Laid-Open No. 9-433223. When explaining the known flux gate type magnetic sensor in detail,

First of all, the sensor core may be a flat amorphous core or a ring amorphous core. The magnetic field detecting coil substrate includes a first detecting coil substrate having a coil pattern for forming an X-axis direction component magnetic field detection coil, and a second detecting coil substrate having a coil pattern for forming a Y-axis direction component magnetic field detection coil. The exciting coil substrate has an annular coil pattern for forming an exciting coil. In the edge portion of the sensor substrate, a through hole connected to each coil pattern is formed.

The geomagnetic sensor having the above-described structure decomposes the geomagnetism into the X-axis direction magnetic field component and the Y-axis direction magnetic field component and outputs it as an azimuth signal of analog value.

Meanwhile, the multifunctional battery pack according to an exemplary embodiment of the present invention further includes a map information storage unit 130 in which map information is stored, and outputs the azimuth information detected by the geomagnetic sensor 120 from the GPS receiver 110. Absolute azimuth processing unit 140 correcting the position information to calculate the absolute azimuth angle, map information reading unit 150 to read the map information matching the current position information from the map information storage unit 130, and read The display information further includes a display screen generation unit 160 for superimposing the magnetic position and orientation on the map information and generating a display screen on which the map information is dynamically rotated according to the change of the magnetic position.

The absolute bearing processor 140, the map information reader 150, the display screen generator 160, and the exercise amount calculator 170, which will be described later, may be implemented as a one-chip controller that controls overall operations of the battery pack.

The main body interface unit 180 interfaces the display screen generated by the display screen generating unit 160 to the main body terminal 200 or interfaces calorie consumption information obtained by the exercise amount calculating unit 170 to be described later to the main body terminal 200. It plays a role.

In addition to the above-described configuration, the multifunction battery pack 100 according to the embodiment of the present invention may further include an exercise amount calculating unit 170. The exercise amount calculator 170 calculates and outputs an exercise amount by calculating and processing azimuth information detected by the geomagnetic sensor 120.

More specifically, first, the azimuth signal from the geomagnetic sensor 120 is decomposed into an X-axis direction (left and right direction) magnetic field vector value and a Y-axis direction (up and down direction) magnetic field vector value. Therefore, the exercise amount calculating unit 170 may count the number of steps of the terminal user coupled to the battery pack 100 by counting the change of the magnetic field vector value in the vertical direction input from the geomagnetic sensor 120. Since the calorie information per step can be stored as an average value, simply multiplying the calories per step by the count reward can calculate the amount of exercise. Accordingly, the exercise amount calculating unit 170 can sufficiently calculate the exercise amount of the terminal user using only the orientation information detected by the geomagnetic sensor 120.

The battery pack 100 having the above-described configuration can be used in combination with the mobile phone body 200 to be described later. Referring to the configuration of such a mobile phone body 200,

First, the wireless unit 230 modulates and frequency-converts the information output from the control unit 220 and transmits it as a wireless signal through the antenna ANT, and a signal other than voice data from the wireless signal received through the antenna ANT. It separates the frequency conversion and demodulation and transmits to the control unit 220.

The voice processor 240 digitally processes the voice input through the microphone MIC under the control of the controller 220, transmits the voice signal to the wireless unit 230, and demodulates the voice data received through the wireless unit 230. Output via (SPK).

The user I / F unit 250 is a concept including a keypad and a display unit, and generates key data according to the keypad operation and transmits the generated key data to the controller 220 to be described later, and displays the display data under the control of the controller 220. State plays a role.

The controller 220 controls the system based on the control program data stored in the internal memory. For example, according to a user's request, the exercise pack may be requested to calculate the amount of exercise or a location-based service is provided, and the display screen information transmitted in response to the request may be output through the user I / F unit 250. give.

Finally, the battery I / F unit 210 is combined with the main body I / F unit 180 to perform data transmission and reception between the battery pack 100 and the main body 200.

Hereinafter, a case in which the battery pack 100 and the cellular phone main body 200 having the above-described configuration are used in combination will be described in more detail. Before describing the operation of the present invention, the prerequisites are that an application program for supporting normal data exchange between the mobile phone main body 200 and the battery pack 100 must be installed in the mobile phone main body 200 in advance. Is that. When satisfying this requirement, the user can use the terminal body 200 coupled to the battery pack 100 as a calorimeter or location information provider.

① When using a battery pack-coupled terminal as a location information provider,

First, the user sets the battery pack 100 as a location information provider through the user I / F unit 250 of the mobile phone main body 200. In this case, the controller 220 of the mobile phone main body 200 transmits a location information provider setting command to the battery pack 100. Then, the display screen generation unit 160 of the battery pack 100 sets the mode to the location information provider and transmits the display screen as described later in real time.

The process of generating the display screen to be transmitted in real time will be described in detail. First, the GPS receiver 110 outputs the current position information (latitude and longitude data) obtained by the radio wave of the received GPS satellite to the absolute defense processor 140. In addition, since the bearing information detected by the geomagnetic sensor 120 is also input to the absolute bearing processor 140, the absolute bearing processor 140 receives the bearing information detected by the geomagnetic sensor 120 in the GPS receiver 110. The absolute absolute azimuth angle is calculated by correcting the current position information. The reason why the absolute absolute azimuth angle can be calculated with respect to the true north direction is that the orientation information can be obtained from the change of the position information of the GPS receiver 110.

Meanwhile, the map information reader 150 reads map information matching the current location information detected from the GPS receiver 110 and applies it to the display screen generator 160. Then, the display screen generating unit 160 displays the location information of the terminal input through the absolute bearing processing unit 140, that is, the current location information and the bearing information, on the read map information, but the user's direction is directed toward the true north direction. The map information is rotated clockwise or counterclockwise by the calculated absolute azimuth angle.

Therefore, the terminal user is able to check his current location on the map while being provided with a surrounding map facing the north through the display unit of the terminal body 200.

② If you use a battery pack terminal as a calorie meter,

First, the user sets the battery pack 100 as a calorie meter through the user I / F unit 250 of the mobile phone main body 200. In this case, the control unit 220 of the mobile phone body 200 transmits a calorimeter meter setting command to the battery pack 100. If there is a calorie meter setting command, the exercise amount calculating unit 170 of the battery pack 100 sets the mode of the battery pack 100 to a calorie meter and then uses the azimuth signal output from the geomagnetic sensor 120 to determine the user's terminal. Calculate your momentum That is, the exercise amount calculating unit 170 counts the change of the magnetic field vector value in the vertical direction input from the geomagnetic sensor 120 to count the number of steps of the terminal user coupled to the battery pack 100 in real time. In addition, the amount of exercise data obtained by multiplying calorie information per step by the real time counted reward data is output in real time through the main body I / F unit 180. At this time, the output of the exercise amount is displayed on the display by the controller 220 of the mobile phone main body 200, the terminal user can visually check the calorie information consumed by walking.

Therefore, when the multi-function battery pack 100 according to the embodiment of the present invention is used in combination with the terminal, the terminal itself can be used as a calorimeter and a location information provider.

Meanwhile, as shown in FIG. 2, the multifunctional battery pack according to the embodiment of the present invention includes a control unit including a GPS receiver 110, a geomagnetic sensor 120, an absolute bearing processor 140, and an exercise amount calculator 170. 190 and the main body I / F unit 180 may be included. The reason for configuring the battery pack 100 as described above is to utilize the map information storage unit in the terminal 200.

That is, the battery pack 100 according to another embodiment of the present invention simply interfaces the current position information and the orientation information obtained through the GPS receiver 110 and the geomagnetic sensor 120 with the terminal body 200, The absolute azimuth information obtained from the absolute bearing processor 140 may be interfaced together with the terminal body 200 to process the information in the terminal body 200 to support location-based services. Since the battery pack does not need a storage means for storing map information, the battery pack can be miniaturized and the manufacturing cost can be reduced.

As described above, the present invention provides the map information in which the current location and the orientation information of the terminal user are superimposed from the battery pack to the terminal body, so that the user can display his current location and its surrounding map information and orientation information through the terminal display unit. It can be provided with the advantage that the accurate navigation is possible.

In addition, the present invention has the advantage that the terminal can be utilized as a calorie meter because it calculates and displays the amount of exercise according to the movement of the terminal user by calculating the azimuth information detected by the geomagnetic sensor.

On the other hand, the present invention has been described with reference to the embodiments shown in the drawings, which are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
