DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be noted that the same components of the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, when a part is referred to as "including " an element, it does not exclude other elements unless specifically stated otherwise.

1 is a configuration diagram of a synchronization and control system according to an embodiment of the present invention.

As shown, the synchronization system according to the embodiment of the present invention includes a smart device 10, peripherals 20a and 20b, an OTG cable 30, and a USB cable 40. [

The smart device 10 may be a smart phone, a tablet PC, a PDA, or the like, which is portable and can support a USB host function. The smart device 10 includes an application for synchronization and control, And a list of supported peripheral devices 14 is stored in an internal memory.

The target peripheral list 14 is a list of USB peripherals supported by the smart device 10 and includes a name of a supporting peripheral device, a name of a manufacturer, a type of a peripheral device, a model number, ID, and the like.

The synchronization application 12 can check the list of supported peripheral devices 14 to know which operating system (OS) is applicable to a specific product family of USB peripheral devices.

When recognizing the connection of the USB connector 40 formed on the OGT cable 30, the smart device 10 supporting the USB host function creates an external storage device, that is, a removable disk.

When the user completes the generation of the removable disk, when the user activates the synchronizing app 12, the synchronizing app 12 runs temporarily and reads the USB information of the peripherals 20a and 20b connected to the smart device 10 and its peripheral devices And checks whether the information is present in the list of supported peripheral devices 14 to determine whether or not the information is an operation control target.

The temporary synchronization application 12 may be configured to synchronize and operate the peripheral devices 20a and 20b when the peripheral devices 20a and 20b connected to the smart device 10 are operation control objects, It is activated and runs normally.

When the synchronization application 12 is normally executed, the user can control the slaves' peripheral devices 20a and 20b connected to the smart device 10 through the smart device 10 as a host.

If the peripheral devices 20a and 20b connected to the smart device 10 judge that they are unsupportable peripherals, the temporarily executed synchronizing app 12 can recognize that the unsupported peripheral device is a peripheral device, And forcibly stops the execution of the temporarily executed synchronization app 12.

This makes it possible to prevent malfunctions or unusable states of the peripheral devices 20a and 20b from being erroneously operated.

The peripheral devices 20a and 20b may be any terminal device capable of functioning as a removable disk when the USB device is connected to the smart device 10 such as a PDA, a digital camera, an MP3 player, and an electronic pen.

When the USB connector 40 formed on the OGT cable 30 is connected to the smart device 10, the peripherals 20a and 20b recognize that the peripheral devices 20a and 20b are connected to the removable disk mode and store the memory built in the peripherals 20a and 20b Make a removable disk.

The USB connector 40 is a combination of a plug and a receptacle. Generally, the plug is integrally formed at both ends of the OTG cable 30, and the receptacle is integrally formed with the smart device 10 and peripheral devices 20a and 20b And the peripherals 20a and 20b are connected to the smart device 10 by inserting the plug into the receptacle.

The OTG cable 30 recognizes the smart device 30 as a USB host when the peripheral devices 20a and 20b are connected to the smart device 10. [

FIG. 2 is a view showing a USB connector used by the smart device shown in FIG. 1 for recognizing a USB host, and particularly shows a USB plug among the USB connector 40. FIG.

The USB plug has a standard type (40a), a mini type and a micro type (40b) according to a shape, not a scale, and classified into A type and B type in each type.

In the figure, a white portion is a concave space in which a receptacle (not shown) is inserted, and a pin number given to the plug 42 is a pin number of the receptacle to which the receptacle is connected. The first pin of the plug is connected to the first pin Respectively.

As shown in the figure, the standard type 40a is composed of four pins, and the mini type supporting the USB host and the micro type 40b are composed of five pins.

In the four-pin standard type (40a), Pin 1 is a VBUS pin for supplying power, Pin 2 and Pin 3 are D-pin and D + pin for transmitting data, Pin 4 is a ground pin GND pin.

In the 5-pin mini-type and micro-type (40b) supporting the USB host, pin 1 is a VBUS pin for supplying power, and pins 2 and 3 are D- and D + pins Pin 4 is the ID pin for the host and slave and pin 5 is the GND pin for the signal ground.

When the pin 5 for signal grounding is connected to the pin 4 in the mini- and micro-type 40b, the device in the direction is a host (smart device). If not connected, the device in the direction is a slave (peripheral device).

FIG. 3 is a view showing an OTG cable used when connecting a smart device and a peripheral device shown in FIG. 1;

In the OTG cable 30 as shown in FIG. 3, the fourth pin is connected to the fifth pin ground to inform the smart device 10 that the peripheral devices 20a and 20b are connected.

4 is a view showing an internal wiring of the OTG cable shown in Fig.

4, when the ID signal line 32 of either plug in the OTG cable 30 is short-circuited (connected) to the GND signal line 34, the device (device) into which the plug 42 is drawn When the ID signal line 36 of the plug is not short-circuited with the GND signal line 34, the device into which the plug 44 is drawn acts as a slave.

As a result, in the present invention, the plug 42 is connected to the smart device 10, and the plug 44 is connected to the peripherals 20a and 20b.

5 is a flowchart of a synchronization and control method according to an embodiment of the present invention.

5, the USB plug 42 of the OTG cable 30 connected to the peripheral devices 20a, 20b is inserted into the receptacle of the smart device 10, and the peripheral devices 20a, 20b are connected to the smart device 10 If the connection is established (S502), the peripheral devices 20a and 20b first recognize the USB connection and switch to the removable disk mode to make the built-in memory a removable disk (S504).

At this time, the smart device 10 also recognizes the connection and creates an external storage device, i.e., a removable disk, in the smart device (S505).

When the creation of the removable disk is completed in the smart device 10, the user starts the synchronization application 12 mounted on the smarty device 10 (S506), and the synchronization application 12 is temporarily executed and connected USB information of the peripheral devices 20a and 20b and peripheral devices is collected and analyzed (S508).

The temporarily executed synchronization application 12 checks whether the analyzed peripheral device is present in the self-stored supported peripheral device list 14 and judges that the peripheral devices 20a and 20b are supportable peripheral devices if they are present, , And 20b (S510).

In step 510, for example, it is determined whether the name of the peripheral device and the USB producer and the seller ID of the peripheral device exist in the self-stored supported peripheral device list 14 to determine whether or not the peripheral device is a supportable peripheral device.

If the synchronization application 12 is found to be a supportable peripheral device in step S510, the temporarily executed synchronization application 12 is normally executed (S512), and then the user executes the normal operation of the synchronization application 12, And the peripheral devices 20a and 20b connected to the control unit 20 can be controlled in synchronization with each other (S514).

If it is determined in step S510 that the peripheral device is an unsupportable peripheral device, the temporarily executed synchronization app informs the user through the speaker or the screen that the connected peripheral devices 20a and 20b are unsupportable peripheral devices, and forcibly suspends the execution of the peripheral device in step S516.

By the forcible stopping of the synchronization app 12 that is temporarily running, the disabled state of the peripheral device due to the erroneous operation can be prevented in advance.

The peripheral devices 20a and 20b can not be synchronized with the smart device 10 and then operate as a simple removable disk (S518).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.

The smart device according to the present invention uses a smart phone, a tablet PC, a PDA, and the like, which are easy to carry and easy to use wireless network, and can be used for all devices supporting the USB host function, It is available for all terminal equipments that have a function as a removable memory (disk) when connected to a USB device.
