The port portion 120 may include ports coupled to the other end of the connection cable 110. The port unit 120 may include a plurality of ports, and a connection cable 110 may be connected to each port. Therefore, the electronic device anti-theft device 100 can connect the electronic device 1 by the number of ports included in the port unit 120. [ Conventionally, when the electronic device anti-theft device is manufactured, it is previously set to include a certain number of ports, so that it is impossible to adjust the number of ports as needed. In other words, there are difficulties in inventory management, production management and the like through demand forecasting because each of them produces an anti-theft device having a fixed number of ports such as 2-port, 4-port, and 6-port. On the other hand, the electronic device anti-theft device 100 according to an embodiment of the present invention can be realized by combining the port unit 120 with a plurality of port modules including one or more ports, It is possible to easily adjust the number of ports included in the portable terminal 100. That is, it is possible to have a desired number of ports by adjusting the number of port modules coupled to the port unit 120, thereby improving the usability of the electronic device anti-theft device.

Furthermore, the port module may each include a coupling detector, and the port unit 120 may generate coupling information of the port modules coupled to the port unit 120 using a coupling detector. Here, the coupling detector may sense another port module or sense a coupling signal output from the other port module. In this case, the port unit 120 may be connected to the port module 120 coupled to the port unit 120 by using a coupling signal. In this case, The number of port modules, the number of ports included in each port module, and the like. Meanwhile, the port unit 120 may transmit the generated binding information to the main control unit 140.

The power supply unit 130 may supply the charging voltage or the charging current to the electronic device 1 through the connection cable 110 and the port unit 120. The power supply unit 130 can receive power from a commercial power source and distribute the supplied power to the main control unit 140 and the electronic device 1 and the like. At this time, depending on the embodiment, the main control unit 140 can set the charge voltage or the charge current. On the other hand, when the electronic apparatus 1 is connected to the connection cable 110, since the power supply unit 130 continuously supplies the charging voltage or the charging current, even when used by a visitor or the like, The state of charge can always be maintained above a certain level. Since the charging voltage or the charging current is supplied to the electronic apparatus 1 through the power supply unit 130, the port unit 120 and the connection cable 110, It is possible to determine whether the cable 110 is disconnected or whether the electronic device 1 is disconnected. In addition, a built-in battery or the like may further be included in the power supply unit 130 in order to maintain power supply to the main control unit 140 and the electronic device 1 even in an emergency such as a power failure.

The main control unit 140 may perform general control of the electronic device anti-theft device 100 and monitor the charging voltage or the charging current supplied from the power supply unit 130 to the electronic device 1. [ That is, the main control unit 140 can detect whether the connection cable 110 is disconnected by detecting a change in the charging voltage or the charging current. If the connection cable 110 is determined to be disconnected, the main control unit 140 generates a theft signal . Here, the disconnection of the connection cable 110 is performed when the connection cable 110 is disconnected from the port unit 120 or when the connection cable 110 is disconnected from the electronic device 1 or when the connection cable 110 itself is cut And may be broken. According to an embodiment, the main control unit 140 further includes an additional disconnection detection circuit. When the disconnection detection circuit senses disconnection of the connection cable 110, the main control unit 140 receives a disconnection signal from the disconnection signal, Can be generated. Here, the disconnection detection circuit may be a simple circuit device that detects when the current flow is interrupted.

The main control unit 140 may receive the binding information for the port modules from the port unit 120 and may use the binding information to determine the charging voltage Or charge current can be set. The number of connectable electronic devices 1 is determined according to the number of ports included in the port unit 120 so that the charge voltage or the size of the charge current distributed by the power supply unit 130 can be determined by the number of electronic devices 1 ≪ / RTI > Therefore, the main control unit 140 can previously set the charge voltage or the charge current to be distributed to the port unit 120 by the power supply unit 130 in advance using the combination information. If the setting value of the charging voltage or the charging current set by the main control unit 140 in accordance with the coupling information is out of the allowable range, etc., the power supply unit 130 may be set to a permissible range or the like , And the main control unit 140 may generate the warning signal. In this case, the administrator can confirm that the set value of the charging voltage or the charging current is out of the allowable range of the power supply unit 130 by the warning signal, so that the manager can adjust the number of port modules, Can be replaced.

The alarm unit 150 may include a speaker or a display device and may output an audible or audible alarm signal such as a warning sound or a warning signal when the theft signal is inputted from the main control unit 140. [ The alarm unit 150 may stop the output of the alarm signal only when the alarm signal is received through the main control unit 140, the management terminal 170, or a separate remote controller. The alarm unit 150 may also output a warning sound or a warning message corresponding to the warning signal when the alarm signal is input from the main control unit 140. [

The network unit 160 may form a network including the electronic device 1 by using wire communication or wireless communication. Here, the network unit 150 may support a wired communication network including cable communication, optical communication, and the like, and may support wireless communication including Wi-Fi, WiBro, WCDMA, Bluetooth, infrared communication, RFID, NFC, . For example, the network unit 150 may perform wired communication through an electronic device and a connection cable 110, or may perform wireless communication with an electronic device via a wireless LAN or the like. A network including the electronic devices 1 connected to the electronic device anti-theft device 100 by the network unit 150 may be formed, and then the management of each electronic device 1 And so on. For example, when an event occurs in which one electronic device 1 is disconnected from the connection cable 110, the main control unit 140 controls the electronic device 1 separated from the connection cable 110 through the network unit 150 , So that the electronic device 1 can be controlled to operate in the stolen mode. In addition, the management terminal 170 and the like can access the network formed by the network unit 160 and perform various management including monitoring for the electronic device 1 and the like.

The management terminal 170 can monitor the operation of the electronic device 1 by using the usage information of the electronic device 1 that receives through the network. That is, the electronic device 1 may be set in advance to transmit the usage information to the management terminal 170. This may be a dedicated application installed in the electronic device 1, Mode or the like. Here, the usage information transmitted by the electronic device 1 includes information such as whether or not the electronic device 1 is used, whether or not the power source is connected, the amount of charge, the position information of the electronic device 1, the software version information of the electronic device 1, 1), and the like. For example, as shown in FIG. 3, electronic devices 1 displayed in the store can be displayed on the display unit of the management terminal 170, and the power supply to the electronic devices 1, Whether it is currently being used by a visitor or the like can be displayed. 4, when an abnormality occurs in the charging voltage or the charging current supplied to the electronic device 1, a guidance message can be output, and the connection cable 110 can be completely coupled The user can output a guidance message for connection abnormality or the like. Further, if a specific electronic device 1 is not used for a preset time or longer, a guide message for guiding an error to the electronic device is output, or software version information installed in an electronic device or the like is checked, And a function of providing guidance for the user. Therefore, the administrator can monitor the state of the electronic device 1 or the like through the management terminal 170. [

In addition, the management terminal 170 can generate statistical information on the usage time by location, model, and color of each electronic device 1 using the usage information, Statistical information on the usage time of each of the applications can be generated. That is, the manager can check which model among the various electronic devices 1 displayed in the shop is interested by the visitors through the management terminal 170, and determine the location of the electronic device 1 in the store, 1), the preference of visitors according to the type of the electronic device 1, and the like.

In addition, when receiving the theft signal from the main control unit 140, the management terminal 170 may transmit a control signal for switching the corresponding electronic device 1 to the stolen mode through the network. Here, the stolen mode may restrict the electronic device 1 to support only a minimum function including emergency call, incoming call reception, and location information transmission, and the electronic device 1 that has switched to the stolen mode is in a stolen state It is possible to repeatedly output a time or audible alarm signal indicating that the corresponding signal is present. The management terminal 170 can also receive the location information of the electronic device 1 from the electronic device 1 that has been switched to the stolen mode and, depending on the embodiment, It is also possible to receive one image. That is, the management terminal 170 can receive the location information of the stolen electronic device 1 and track the stolen electronic device 1. In some embodiments, after the connection cable 110 is disconnected, It is possible to secure proof of the face of the person who took the electronic device 1, the impression of the impression, and the like.

In addition, the management terminal 170 can perform a function of controlling the operation of the alarm unit 160. [ Therefore, even when a plurality of electronic device theft prevention devices exist in the store, the operation of the alarm portion 160 of the electronic device theft prevention device can be easily stopped. Conventionally, a separate remote controller is utilized. In this case, however, there has been a problem in management such as an electronic device theft prevention device in which an alarm signal is generated and a remote controller corresponding thereto. However, according to an embodiment of the present invention, the operation and the release of the alarm unit 160 of the electronic device antitheft device can be intuitively managed through the management terminal 170, It is possible to more easily control the operation and release of the alarm signal.

The port unit 120, the power supply unit 130, the main control unit 140, and the network unit 150 included in the electronic device theft prevention apparatus according to an exemplary embodiment of the present invention are modules And each module can be added, exchanged or removed individually. At this time, each module may include a coupling detector, and the main control unit 140 may collect information on the type of the coupled module and the like from the coupling detector.

2 is a block diagram showing an electronic device theft prevention apparatus according to another embodiment of the present invention.

2, an electronic device theft prevention apparatus 200 according to another embodiment of the present invention includes a position sensing unit 210, a main control unit 220, an alarm unit 230, and a management terminal 240 can do.

Hereinafter, an electronic device anti-theft device according to another embodiment of the present invention will be described with reference to FIG.

The position sensing unit 210 may be connected to the electronic device 1 by wireless communication to sense a communication signal of the electronic device 1. [ A plurality of electronic devices 1 can be connected to the position sensing unit 210 at the same time and the position sensing unit 210 recognizes information about the speed and intensity of the communication signal sensed by the electronic device 1 . The position sensing unit 210 may be implemented as a wireless router or the like and the position sensing unit 210 may connect the electronic devices 1 and the like to each other via a wireless communication network, It is possible to make communication between the electronic apparatus 1 and the electronic device theft prevention device 200 possible. Furthermore, the position sensing unit 210 may connect the electronic devices 1 to the Internet, an intranet, or the like. Here, the position sensing unit 210 may distinguish a plurality of electronic devices 1 by using an identifier included in the communication signal.

The main control unit 220 can determine the position of the electronic device 1 using the communication signal received by the position sensing unit 210. If it is determined that the electronic device 1 is spaced apart from the predetermined allowable distance It is possible to generate a theft signal. Here, when a plurality of electronic devices 1 exist, different electronic devices 1 can be distinguished from each other by using an identifier included in the communication signal. Generally, since the intensity of the communication signal is inversely proportional to the distance, when the distance between the electronic device 1 and the position sensing unit 210 increases, the intensity of the communication signal gradually decreases. Accordingly, the main control unit 220 can determine whether the electronic apparatus 1 is spaced by a predetermined allowable distance or not by detecting the intensity of the communication signal. For example, the allowable distance that the electronic device 1 can be separated from the position sensing unit 210 may be predetermined, and the intensity of the communication signal at the allowable distance may be set as a limit signal strength. In this case, the main control unit 220 can compare the intensity of the communication signal received from the electronic device 1 with a preset limit signal strength, and if the intensity of the received communication signal is less than the limit signal strength, (1) is spaced more than the allowable distance. According to an embodiment, the wireless communication connection with the electronic device 1 may be disconnected if the intensity is below the limit signal strength, and the main control unit 220 may generate a theft signal when the wireless communication connection is disconnected .

Also, the main control unit 220 can generate the theft signal even when the wireless communication between the position sensing unit 210 and the electronic device 1 is broken in a manner other than the predetermined release process. For example, there may be a boundary mode for detecting the position of the electronic device 1 and generating a theft signal, and an unlocking mode for stopping the detection of the position of the electronic device 1 in the electronic device anti-theft device. In this case, if the wireless communication between the position sensing unit 210 and the electronic device 1 is interrupted while the main control unit 220 is operating in the boundary mode, a stolen signal can be generated. On the other hand, after the main control unit 220 is switched from the border mode to the release mode, the wireless communication between the position sensing unit 210 and the electronic device 1 is interrupted, or when the electronic device 1 It is possible not to generate a stolen signal even if it is spaced apart.

The alarm unit 230 may include a speaker or a display device and may output an audible or audible alarm signal such as a warning sound or a warning message when the theft signal is inputted from the main control unit 220. Here, the alarm unit 230 may increase the output intensity of the alarm signal or shorten the output period in inverse proportion to the intensity of the communication signal received by the main control unit 220. For example, if the intensity of the communication signal is less than the threshold signal intensity, the alarm unit 230 starts to output a warning sound, and as the intensity of the communication signal decreases, the warning sound can be increased or the warning sound can be output more quickly. Through this, it is possible for the visitor to recognize that the electronic device 1 is gradually separated from the allowable distance.

Meanwhile, the theft signal generated by the main control unit 220 may be transmitted to the wireless communication network through the position sensing unit 210, and the stolen electronic device 1 may receive the stolen signal. In this case, the electronic device 1 can output a warning sound or the like, warns that the electronic device 1 is separated from the allowable distance by the display unit or the like, and outputs a guidance message to guide the user to return the electronic device 1 can do. According to the embodiment, the electronic device 1 can switch to the stolen mode in response to the stolen signal.
