1 is a block diagram of a short circuit protection system using a smart multi-tap according to an embodiment of the disclosed technology. And Figure 2 is a block diagram of a smart multi-tap according to one embodiment of the disclosed technology. Referring to FIGS. 1 and 2, a short circuit protection system using a smart multi-tap includes a switchboard 110, a smart multi-tap 120, and a smart terminal 130. The switchboard includes a control unit 110a and a communication unit 110b. The smart multitap 120 includes a power supply unit 121, a control unit 122, an LED 123, and a communication module 124.

The switchboard 110 monitors the amount of power supplied to the smart multi-tap 120 and cuts off the power supplied to the smart multi-tap 120 according to a control signal transmitted from the smart multi-tap 120. In one embodiment, the switchboard 110 can receive power supplied from the KEPCO and supply the load to a load such as a multi-tap or an electronic device connected to each line, and can monitor whether the amount of supplied power exceeds a threshold value.

On the other hand, the switchboard 110 receives the control signal from the smart multi-tap 120 in addition to monitoring the state of the electric power. And cut off the power supplied to the smart multitap 120 according to whether the control signal is received or not. The smart multi-tap 120 transmits a control signal to the switchboard 110 when the amount of power supplied exceeds a preset first reference value.

That is, the switchboard 110 and the smart terminal 120 monitor the amount of power on both sides using the threshold value and the first reference value, respectively. In one embodiment, the switchboard includes a control unit 110a. When the state of the monitored power exceeds a threshold value and a control signal is transmitted from the smart multi-tap 120, the control unit 110a is used to control the smart multi- Thereby shutting off the supplied power. That is, when both the conditions are satisfied, the control unit 110a can control the power receiving switch or the power distribution switch of the switchboard 110 to cut off the power supply. Here, the threshold value of the switchboard 110 and the first reference value of the smart multi-tap 120 may be set differently from each other.

Meanwhile, referring to FIG. 5, the operation flow of the switchboard 110 can be confirmed. In one embodiment, the power receiving state of the external power supplied from the KEPA may be monitored according to the step S510 of the switchboard 110. [ If the power state does not exceed the threshold value, the state of the power supply and demand is continuously monitored. If the power state exceeds the threshold value, the control signal is received in step S520. If the control signal is not received, the process returns to step S510 to monitor the state of the power supply and, if the control signal is received, the switch is turned off according to step S530.

On the other hand, the switchboard 110 includes a communication unit 110b. When the power supply exceeds the threshold value of the switchboard 110 itself and exceeds the first reference value of the smart multi-tap 120, the control panel receives the control signal and cuts off the power supply to the line connected to the smart multi-tap 120 This information can be transmitted to the smart terminal 130 using the communication unit 110b. In one embodiment, the switchboard 110 may transmit information according to the amount of power state to the smart terminal 130 so that the user of the smart terminal 130 may monitor which line of the switchboard 110 is switched off. Here, the communication unit 110b can communicate with the smart terminal 130 through the DLMS / COSEM protocol.

The smart multi-tap 120 is provided with at least one socket to which an electronic device is connected, and determines the operation state of the electronic device by sensing an amount of power input from the outside and output to the socket. 3, the smart multi-tap 120 includes a power supply unit 121, and controls the amount of external power supplied from the power distribution board 110 through the power supply unit 121 and the amount of power to be removed from each socket Can be detected. The power supply unit 121 includes a power controller 121a, and a switch for supplying power to each socket can be controlled using a power controller 121a.

Meanwhile, the smart multi-tap 120 stores a first reference value for the amount of power supplied from the switchboard 110 and a second reference value ranging from a minimum reference value to a maximum reference value. For example, the second reference value may be a value ranging from 100 amperes to 500 amperes. The smart multi-tap 120 may use this second reference value to sense whether the amount of power output to the socket to which the electronic device is connected is less than a minimum reference value or exceeds a maximum reference value. In one embodiment, the smart multi-tap 120 includes a control unit 122, and the control unit 122 is used to sense that the electronic device is connected, and if the power consumption of the electronic device is less than the minimum reference value, Or between the first reference value and the second reference value.

On the other hand, if the smart multi-tap 120 detects that the electronic device is connected through the control unit 122 to set the second reference value, the smart multi-tap 120 transmits a default value of the consumed power and standby power of the electronic device from the input / It is possible to receive. In one embodiment, the smart multi-tap 120 includes a communication module 124, and when the control module 122 senses that it is electrically connected to the input / output unit of the electronic device through the socket, Communication can be performed to receive a default value.

In another embodiment, when an electronic device is connected to a socket of the smart multi-tap 120, the smart terminal 130 transmits a default value of consumed power and standby power of the corresponding electronic device to the communication module 124 of the smart multi- As shown in FIG. At this time, the communication module 124 and the smart terminal can perform communication through a short-range wireless communication method such as Bluetooth, NFC, or RFID.

Meanwhile, referring to FIG. 6, the smart multi-tap 120 can operate according to the following procedure. The smart multi-tap 120 detects the connection of the electronic device in step S610. For example, a current sensor or a voltage sensor may be provided for each socket to detect whether the electronic device is connected or not according to a change in current or voltage. If the connection of the electronic device is not detected, it can be continuously monitored to see if the plug is connected to the socket.

When the connection of the electronic device is detected, the multi-tap 120 receives a default value from the electronic device in step S620. For example, as described above, a default value can be received by communicating with an input / output unit mounted on an electronic apparatus. Upon receiving the default value, the multi-tap 120 determines whether the power consumption of the electronic device exceeds the first reference value in step S630. If the power consumption exceeds the first reference value, the multi-tap 120 transmits a control signal to the switchboard 110 And if it does not exceed the first reference value, it can be compared with the second reference value in step S650.

On the other hand, when the power consumption of the electronic device is less than the minimum value of the second reference value or exceeds the maximum value, the multi-tap 120 interrupts the power supply by interrupting the switch of the socket to which the electronic device is connected in step S660. If the power consumption falls within the second reference range, the power consumption can be continuously monitored while maintaining the power supply.

On the other hand, when the power consumption of the electronic device is less than the minimum value or exceeds the maximum value of the second reference value as described above, the multi-tap 120 cuts off the switch of the socket to which the corresponding electronic device is connected. The control unit 122 of the smart multi-tap 120 transmits a power control signal to the power supply unit 121 and the power supply unit operates the power supply controller 121a based on the power control signal, The switch can be turned off. When the smart multi-tap 120 switches off the socket, the smart terminal 130 transmits information according to the power consumption. In an embodiment, the communication module 124 may be used to wirelessly transmit information according to the amount of power used as in the case of receiving a default value of the electronic device.

Meanwhile, the smart multi-tap 120 includes an LED 123 for displaying information on power consumption of each of a plurality of sockets on one side of the body. The LED 123 intuitively displays information on the power consumption. As shown in FIG. 4, it is possible to display the power consumption amount for each socket by disposing it on the side surface of the multi-tap 120 in one embodiment. Here, the LED 123 may use numerical values or visual elements so that the user can intuitively check the power consumption. Of course, as shown in FIG. 4, it is possible to intuitively check the power consumption through the elements visually displayed by the user using both of them.

The smart terminal 130 receives information according to the amount of power consumption in the smart multi-tap 120 and information according to the power amount state in the switchboard 110 and performs monitoring. The smart terminal 130 can receive information according to the amount of power consumption and information according to the amount of power state every predetermined period and perform monitoring. In one embodiment, the smart multi-tap 120 and the switchboard 110 have the same period in advance and can transmit power status information and power usage information to the smart terminal 130 according to the period.

Here, it is assumed that the smart terminal 130 is located close to the smart multi-tap 120 and the switchboard 110. For example, it is preferable that the smart terminal 130 is located within a distance not too far away so as to receive data from the switchboard 110 and the smart multi-tap 120 using short-range wireless communication such as Bluetooth. In this regard, the smart terminal 130 may include an application for generating a notification when a distance from the switchboard 110 and the smart multi-tap 120 is more than a predetermined distance.

Referring to FIG. 7, the smart terminal 130 may receive information on power consumption and display corresponding information on each screen on a screen. The smart terminal 130 receives information according to the power status and information on the power usage from the communication unit 110b of the switchboard 110 and the communication module 124 of the smart multi-tap 120, An application that can monitor the information at a glance can be provided. The status of the switchboard 110, the socket order of the smart multi-tap 120, the status of the electronic device, the power usage status, the power consumption amount, and the power off time can be displayed on the screen of the smart terminal 130 through the application.

Referring to FIG. 7, a user of the multi-tap 120 uses his / her smart terminal 130 to connect an electronic device connected to a first socket normally and maintain a standby power state, and an electronic device connected to a second socket And the amount of power consumed is about 40%, and the electronic device connected to the third socket is able to check when the switch is shut off due to a short circuit and when the power is cut off. Accordingly, the user can monitor the switchboard 110 and the smart multi-tap 120.
