In other words, the terminals 300A, 300B, and 300C may be three as shown in FIG. 1, or may be one or more. The number of terminals 300A, 300B, and 300C may be determined according to the environment and / or conditions in which the network terminal management system according to an embodiment of the present invention is installed.

A gateway 100 according to an embodiment of the present invention may refer to various devices for relaying data transmission and reception between the terminals 300A, 300B and 300C and a server 200 described later.

For example, when the terminals 300A, 300B and 300C are image capturing apparatuses as in the above-mentioned example, the gateway 100 can receive images from the terminals 300A, 300B and 300C and transmit them to the server 200 have.

A plurality of gateways 100 according to an embodiment of the present invention may be plural. When there are a plurality of gateways 100, the terminals to be served by each gateway 100 may be different from each other. For example, if the network terminal management system includes two gateways and ten terminals are included, five terminals may be served by the first gateway and the remaining five terminals may be served by the second gateway.

On the other hand, which gateway is responsible for which terminal depends on the relative installation position of each gateway and / or the terminal. Assume, for example, that the network terminal management system includes two gateways, ten terminals, four of the terminals are densely installed, and the remaining six terminals are densely installed, as in the above-described example Let's see. In this case, the first gateway may be responsible for four terminals, and the second gateway may be responsible for the remaining six terminals.

For example, the server 200 may receive an image acquired by the terminals 300A, 300B, and 300C through the gateway 100, and then store the received image.

Meanwhile, the server 200 according to another embodiment of the present invention may include a network terminal management apparatus (110 of FIG. 2) described later.

2 schematically shows a configuration of a network terminal management apparatus 110 according to an embodiment of the present invention.

Referring to FIG. 2, the network terminal management apparatus 110 may include a control unit 111, a memory 112, and a communication unit 113.

The controller 111 according to an embodiment of the present invention may include all kinds of devices capable of processing data, such as a processor. Herein, the term " processor " may refer to a data processing apparatus embedded in hardware, for example, having a circuit physically structured to perform a function represented by a code or an instruction contained in the program. As an example of the data processing apparatus built in hardware, a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC) circuit, and a field programmable gate array (FPGA), but the scope of the present invention is not limited thereto.

The memory 112 according to an exemplary embodiment of the present invention performs a function of temporarily or permanently storing data processed by the network terminal management device 110. The memory 112 may include magnetic storage media or flash storage media, but the scope of the invention is not so limited.

The communication unit 113 according to an exemplary embodiment of the present invention allows a network terminal management apparatus 110 to transmit a signal such as a video signal or a control signal through a wire / wireless connection to the server 200 and / or the terminals 300A, 300B, And may be a device including hardware and software necessary for transmitting and receiving.

Meanwhile, the network terminal management apparatus 110 may be included in at least one of the gateway 100 and the server 200 as described above. The network terminal management device 110 is not included in the gateway 100 and the server 200, and may be configured independently.

In the following description, it is assumed that the network terminal management apparatus 110 is included in the gateway 100 for convenience of explanation.

The control unit 111 of the network terminal management apparatus 110 according to an embodiment of the present invention broadcasts a first signal to one or more terminals 300A, 300B, and 300C in a first communication mode, The terminals 300A, 300B, and 300C may receive one or more second signals transmitted in response to the first signal.

The 'first communication mode' according to the present invention is a concept distinguished from the 'second communication mode' described later, and can be used temporarily without assigning an identifier for communication according to the second communication mode of the terminals 300A, 300B and 300C Which may be indicative of various communication modes. For example, the first communication mode may be a communication mode according to a Wi-Fi Direct or a Wi-Fi P2P mode, and the second communication mode may be a communication mode according to a conventional Wi-Fi mode.

Of course, the first communication mode and the second communication mode may be communication methods according to different communication standards. For example, the first communication mode may be the communication mode according to the Bluetooth communication standard, and the second communication mode may be the communication mode according to the Wi-Fi mode.

Meanwhile, the 'second communication mode' may be a communication mode in which identifiers are assigned to one or more terminals 300A, 300B and 300C unlike the first communication mode, and data is transmitted and received based on the assigned identifiers. In this case, the identifier may mean, for example, an IP address.

Broadcasting of the first signal in the present invention may mean that the controller 111 transmits the first signal to one or more terminals 300A, 300B, and 300C. Broadcasting of the first signal by the control unit 111 is performed to confirm whether a new terminal is added as described later, and may be periodically or aperiodically performed.

Meanwhile, one or more second signals transmitted by one or more terminals 300A, 300B and 300C in response to the first signals may be signals including identification information of the terminals 300A, 300B and 300C. For example, the second signal may include a MAC address, model number, and authentication information of each of the terminals 300A, 300B, and 300C.

The controller 111 according to an embodiment of the present invention can extract a new terminal based on one or more second signals transmitted by one or more terminals 300A, 300B, and 300C in response to the first signal. In other words, the control unit 111 can check which terminal has been added by comparing the second signal for broadcasting the first signal in the past with the second signal for broadcasting the current first signal. At this time, the second signal for broadcasting the first signal in the past and the data for analyzing the second signal may be temporarily and / or permanently stored in the memory 112.

The controller 111 according to an embodiment of the present invention can assign an identifier for communication according to the second communication mode to the extracted new terminal. For example, if the identifier is an IP address, the control unit 111 may add the IP of the new terminal and add the terminal to the network according to the second communication method.

Then, the controller 111 requests the new terminal for the communication state according to the second communication mode between the extracted new terminal and the new terminal of one or more adjacent terminals, and transmits the communication state from the new terminal to the new terminal .

At this time, the 'communication state' may include the strength of a signal received from one or more adjacent terminals of the extracted new terminal. The 'signal strength' can be, for example, RSSI (Received Signal Strength Indication).

The controller 111 according to an embodiment of the present invention can determine the type of the new terminal based on the communication state received from the new terminal. More specifically, the control unit 111 can determine the installation position of the new terminal based on the strength of a signal received from one or more adjacent terminals of the new terminal included in the communication state. The control unit 111 may determine the type of the new terminal to be one of an alternative terminal and an additional terminal based on the determined location and the location of one or more terminals previously stored. The location of one or more pre-stored terminals may be determined based on a communication state received from another terminal in the past.

In the present invention, 'installation location' may mean a relative positional relationship between a plurality of terminals.

FIG. 3 is an example of the installation of a network terminal management system according to an embodiment of the present invention.

Referring to FIG. 3, it is assumed that a total of four terminals 300A, 300B, 300C, and 300D are installed in a monitoring target space. Although not shown, it is assumed that the gateway 100 and the server 200 are also installed as part of the network terminal management system.

In this case, the control unit 111 can determine the relative positional relationship between the terminals 300A, 300B, 300C and 300D as the installation positions of the terminals 300A, 300B, 300C and 300D.

The control unit 111 may set the installation position of the terminal 300D at a position 5 meters from the first terminal 300A, 5 meters from the second terminal 300B, 4 meters from the third terminal 300C, . On the other hand, such a relative positional relationship can be determined by the signal reception strength between the terminals as described above.

4 is a diagram illustrating a process of the controller 111 of the present invention determining a type of a new terminal as an alternative terminal.

3, a total of four terminals 300A, 300B, 300C and 300D are installed in the monitoring target space. When the terminal 300D receives a new terminal 300D-1 as shown in FIG. 4, . ≪ / RTI >

The control unit 111 may determine the type of the new terminal to be one of an alternative terminal and an additional terminal based on the determined location and the location of one or more terminals previously stored.

More specifically, the control unit 111 may determine the type of the new terminal as an alternative terminal when the distance between at least one of the locations of one or more previously stored terminals and the determined location of the new terminal is less than the threshold distance.

That is, in FIG. 4, the positions of the terminals 300A, 300B, 300C and 300D in FIG. 3 correspond to the positions of one or more terminals previously stored, and the position of the terminal 300D- The control section 111 substitutes the type of the terminal 300D-1 because the distance between the position of the terminal 300D-1 and the position of the terminal 300D of FIG. 3 corresponds to the threshold distance R or less. It can be decided by the terminal.

5 is a diagram for explaining a process in which the controller 111 of the present invention determines a type of a new terminal as an additional terminal.

For convenience of explanation, it is assumed that a total of four terminals 300A, 300B, 300C and 300D are installed in the monitoring target space as shown in FIG. 3, and an additional terminal 300E is installed as shown in FIG.

In this case, the controller 111 can determine the type of the new terminal as either the alternative terminal or the additional terminal based on the determined location and the location of one or more terminals previously stored.

More specifically, the controller 111 may determine the type of the additional terminal 300E as an additional terminal when the distance between the location of one or more pre-stored terminals and the location of the determined additional terminal 300E exceeds the threshold distance.

5, the positions of the terminals 300A, 300B, 300C and 300D in FIG. 3 correspond to the positions of one or more previously stored terminals, and the position of the additional terminal 300E in FIG. 5 corresponds to the position of the additional terminal Since the distance between the position of the additional terminal 300E and the position of the terminal 300D closest to the additional terminal 300E exceeds the critical distance R, the controller 111 determines the type of the additional terminal 300E It can be decided as an additional terminal.

Meanwhile, the controller 111 according to an embodiment of the present invention can transmit / receive a setup profile with a new terminal to correspond to the determined type.

For example, if the type of the new terminal is the alternative terminal, the control unit 111 can transmit the configuration profile of the terminal that is less than the threshold distance to the new terminal to the new terminal. Referring again to FIG. 4, when the terminal 300D is replaced with a new terminal 300D-1, the terminal 300D corresponds to a terminal having a threshold distance R or less than the new terminal 300D- The control unit 111 can transmit the setup profile of the terminal 300D to the new terminal 300D-1.

Meanwhile, the configuration profile of the terminal 300D may be acquired and stored in the memory 112 of the network terminal management apparatus 110 in advance.

In the present invention, the 'set profile' of the terminal may mean the set values of the terminal. For example, if the terminal is an image acquisition device, the setting profile may include the type of the used codec, the image acquisition resolution, the frame rate, and the bit rate. However, the present invention is not limited thereto.

On the other hand, if the type of the new terminal is the additional terminal, the control unit 111 can receive the setting profile of the new terminal from the new terminal and store it in the memory 112. Referring again to FIG. 5, the control unit 111 may receive the configuration profile from the additional terminal 300E and store it in the memory 112. FIG. At this time, the setting profile of the additional terminal 300E can be set by the administrator at the time of installing the additional terminal 300E. Also, the configuration profile of the additional terminal 300E stored in the memory 112 may be transmitted to the replacement terminal when the additional terminal 300E is replaced as described above.

As described above, according to an embodiment of the present invention, a configuration profile of an existing terminal can be applied to a new terminal even when replacing an existing terminal. Thus, an embodiment of the present invention can reduce maintenance, maintenance personnel, time and cost of the network terminal management system.

6 is a flowchart for explaining a network terminal management method performed by the control unit 111 of the network terminal management device 110. As shown in FIG. Hereinafter, the detailed description of the contents overlapping with those described in Figs. 1 to 5 will be omitted.

The control unit 111 of the network terminal management apparatus 110 according to an embodiment of the present invention broadcasts a first signal to one or more terminals 300A, 300B, and 300C in a first communication mode (S61) , One or more terminals 300A, 300B, 300C may receive one or more second signals transmitted in response to the first signal (S62)

Meanwhile, the controller 111 according to an embodiment of the present invention may receive one or more second signals transmitted by one or more terminals 300A, 300B, and 300C in response to the first signal. At this time, the second signal may be a signal including identification information of each of the terminals 300A, 300B and 300C. For example, the second signal may include a MAC address, a model number, and authentication information of each of the terminals 300A, 300B, and 300C. In this case, the first signal is a signal transmitted to the unspecified number of terminals periodically or aperiodically to check whether the network terminal management apparatus 110 has added a new terminal, and the second signal is a signal transmitted from the terminal May be a signal including identification information.

The controller 111 according to an exemplary embodiment of the present invention may extract a new terminal based on one or more second signals transmitted by one or more terminals 300A, 300B, and 300C in response to the first signal. S63) In other words, the control unit 111 can check which terminal has been added by comparing the second signal for broadcasting of the first signal in the past with the second signal for broadcasting the current first signal . At this time, the second signal for broadcasting the first signal in the past and the data for analyzing the second signal may be temporarily and / or permanently stored in the memory 112.

The controller 111 according to an embodiment of the present invention can assign an identifier for communication according to the second communication mode to the extracted new terminal. For example, if the identifier is an IP address, the control unit 111 may add the IP of the new terminal and add the terminal to the network according to the second communication method.

Then, the controller 111 requests the new terminal for the communication state according to the second communication mode between the extracted new terminal and the new terminal of one or more adjacent terminals, and transmits the communication state from the new terminal to the new terminal (S64). At this time, the 'communication state' may include the intensity of a signal received from one or more adjacent terminals of the extracted new terminal. Also, 'signal strength' may mean Received Signal Strength Indication (RSSI), for example.

The controller 111 according to an embodiment of the present invention can determine the type of the new terminal based on the communication state received from the new terminal. More specifically, the control unit 111 can determine the installation position of the new terminal based on the strength of a signal received from one or more adjacent terminals of the new terminal included in the communication state. The control unit 111 may determine the type of the new terminal to be one of an alternative terminal and an additional terminal based on the determined location and the location of one or more terminals previously stored. The location of one or more pre-stored terminals may be determined based on a communication state received from another terminal in the past.

For example, when the distance between at least one of the locations of one or more previously stored terminals and the determined location of the new terminal is less than the threshold distance, the controller 111 may determine the type of the new terminal as the alternative terminal. In addition, when the distance between the location of one or more pre-stored terminals and the determined location of the new terminal exceeds the threshold distance, the controller 111 may determine the type of the new terminal as an additional terminal.

Meanwhile, the controller 111 according to an embodiment of the present invention can transmit / receive a setup profile with a new terminal to correspond to the determined type (S65)

For example, if the type of the new terminal is the alternative terminal, the control unit 111 can transmit the configuration profile of the terminal that is less than the threshold distance to the new terminal to the new terminal. Referring again to FIG. 4, when the terminal 300D is replaced with a new terminal 300D-1, the terminal 300D corresponds to a terminal having a threshold distance R or less than the new terminal 300D- The control unit 111 can transmit the setup profile of the terminal 300D to the new terminal 300D-1.

Meanwhile, the configuration profile of the terminal 300D may be acquired and stored in the memory 112 of the network terminal management apparatus 110 in advance.

In the present invention, the 'set profile' of the terminal may mean the set values of the terminal. For example, if the terminal is an image acquisition device, the setting profile may include the type of the used codec, the image acquisition resolution, the frame rate, and the bit rate. However, the present invention is not limited thereto.

On the other hand, if the type of the new terminal is the additional terminal, the control unit 111 can receive the setting profile of the new terminal from the new terminal and store it in the memory 112. Referring again to FIG. 5, the control unit 111 may receive the configuration profile from the additional terminal 300E and store it in the memory 112. FIG. At this time, the setting profile of the additional terminal 300E can be set by the administrator at the time of installing the additional terminal 300E. Also, the configuration profile of the additional terminal 300E stored in the memory 112 may be transmitted to the replacement terminal when the additional terminal 300E is replaced as described above.

As described above, according to an embodiment of the present invention, a configuration profile of an existing terminal can be applied to a new terminal even when replacing an existing terminal. Thus, an embodiment of the present invention can reduce maintenance, maintenance personnel, time and cost of the network terminal management system.

[

If the type of the terminal determined by the network terminal management apparatus 110 is an additional terminal, the terminal can transmit the current configuration profile to the network terminal management apparatus 110. [
