2 is a schematic structural diagram of a data transmission system according to an embodiment of the present invention.

2, the data transmission system includes a storage medium 100, an external device 200, and a data transmission device 300.

The storage medium 100 stores data such as music files or picture files. The storage medium 100 may be a memory card including any one of a secure digital (SD), a compact flash (CF), an extreme digital (XD), and a memory stick (MS). Alternatively, the storage medium 100 may be implemented as a mass storage medium (HDD).

The external device 200 is a device for receiving data stored in the storage medium 100 and may include a personal computer, a mobile phone, a PDA, a navigation, a PMP, and an electronic dictionary. At this time, the external device 200 is a device that operates using the power supplied from the internal battery as a drive power, a device that operates using AC commercial power as a drive power, and the battery and AC commercial power selectively It can be divided into devices that operate.

The data transmission device 300 is connected to the storage medium 100 and the external device 200, and reads data from the connected storage medium 100 and transmits the data to the external device 200.

Hereinafter, the data transmission device 300 will be described in more detail.

The data transmission device 300 includes a first interface unit 301, a second interface unit 302, a memory unit 303, a battery 304, and a controller 305.

The first interface unit 301 is connected to the storage medium 100 and receives data stored in the connected storage medium 200.

In this case, the first interface unit 301 may be configured in plurality in order to satisfy various communication standards.

The second interface unit 302 is connected to the external device 200, and transmits data received through the first interface unit 301 to the connected external device 300.

In this case, the second interface unit 302 may be configured in plurality in accordance with a communication method between the data transmission device 300 and the external device 200.

That is, when the external device 200 is a personal computer, the second interface unit 302 may be configured as an interface in the form of a PC express. In addition to this, the second interface unit 320 may be configured as an interface in the form of a universal serial bus (USB).

Meanwhile, the second interface unit 320 is a Bluetooth module, a wireless LAN module, a Wi-Fi module, and a UWB (Ultra Wide Band system) module capable of transmitting and receiving data without a separate cable connection. It may be composed of any one.

The memory unit 303 stores data generated during the operation of the data transmission device 300 or data necessary for the operation of the data transmission device 300. In this case, the memory unit 303 may be implemented as the EEPROM.

In addition, the memory unit 303 stores the data received through the first interface unit 301.

The battery 304 is charged by the power supplied from the outside in the first mode, and supplies driving power to each component constituting the data transmission device 300 based on the charged power in the second mode. In this case, the first mode and the second mode are determined by the type of the external device 200 connected to the data transmission device 300.

The controller 305 controls the overall operation of the data transmission device 300.

In particular, the control unit 305 detects that the storage medium 100 is connected to the first interface unit 301, and thus reads data from the connected storage medium 100 and temporarily stores the data in the memory unit 303. Save it.

In addition, the control unit 302 detects that the external device 200 is connected to the second interface unit 302, and accordingly reads data read from the storage medium 100 to the connected external device 200. The second interface unit 302 transmits the data to the external device 200.

In this case, the controller 302 determines the type of the external device 200 connected to the second interface unit 302. That is, the controller 302 is connected to the external device 200 through a separate cable, and determines whether the external device 200 is operated by an AC commercial power input through a power line.

The controller 302 controls the operation of the battery 304 according to the grasping result. That is, when the external device 200 is operated by the AC commercial power supply and connected through a separate cable, the external device 200 cuts off the power output from the battery 304 and is thus supplied from the connected external device 200. The charging of the battery 304 and the operation of the data transmission device 300 are performed based on the power source.

In addition, when the controller 302 is wirelessly connected to the external device 200, the data transmission device 300 operates by the power supplied from the battery 304.

Meanwhile, the controller 305 reads data from the storage medium 100 connected to the first interface unit 301 at the time when the external device 200 is connected to the second interface unit 302, and reads the data. The input data may be transmitted to the external device 200.

However, when data transmission is performed as described above, since the communication between the first interface unit 301 and the external storage medium 100 is to be performed, the transmission speed of the data may be somewhat delayed.

Accordingly, when the storage medium 100 is connected, the controller 305 first reads the data stored in the connected storage medium 100 and stores the data in the memory unit 303, and later the external device 200. When is connected, the data stored in the memory unit 303 is extracted and transmitted to the external device 200.

In addition, the data transmission may be performed at the time of receiving a data transmission command from the connected external device 200, regardless of the time when the external device 200 is connected to the second interface unit 302. Can be.

In addition, the controller 305 may create a specific folder in the storage area of the connected external device 200 to transmit the data, and accordingly, store the data in the generated folder. In this case, the folder generation may be implemented by the operation of the control unit 305, otherwise, the external device 200 may be performed.

3 is a flowchart for explaining a data transmission method of the data transmission apparatus according to an embodiment of the present invention step by step.

Referring to FIG. 3, the storage medium 100 is first connected to the first interface unit 301.

When the storage medium 100 is connected to the first interface unit 301, the controller 305 reads data from the connected storage medium 100 (step 102), and reads the read data from the memory unit 303. In step 103).

In operation 104, the controller 305 determines whether the external device 200 is connected to the second interface unit 302.

As a result of the determination (step 104), when the external device 200 is not connected, the controller 305 returns to the step 102 to continuously read and store the data.

On the other hand, when the determination result (104), when the external device 200 is connected, the control unit 305 generates a folder for storing the read data in the connected external device 200.

In this case, the controller 305 determines the type of the connected external device 200 and receives driving power from the connected external device 200 or the internal battery 304 according to the identified type of the external device 200. ) Is supplied with driving power.

Thereafter, the controller 305 transmits the read data to the external device 200, and accordingly, transmits the transmitted data to the generated folder (step 106).

According to the embodiment of the present invention as described above, it is possible to transfer the photo data or music data, etc. stored in the memory card to the mobile terminal without a separate personal computer, thereby utilizing the data stored in the memory card in the mobile terminal regardless of place Can improve user convenience.
