In this case, the power supply unit 100 is configured to receive power from the outside, and in one example, an auxiliary device for connecting to the object Internet network of the present invention (hereinafter referred to as an auxiliary device) In the case of having an adapter shape as well, the power supply unit 100 receives power from the electric equipment through a plug portion 100a connected to an outlet connected to the electric equipment.

That is, the power supply unit 100 receives power from the electric equipment, and the switch is closed as the plug unit 100a of the auxiliary unit is connected to the socket connected to the electric equipment, and the plug unit 100a of the auxiliary device The power source 100 is supplied with power.

In one example, when the plug portion 100a of the auxiliary device of the present invention having an adapter shape as shown in Fig. 2 is connected to a socket connected to the electric equipment, the switch is closed so that the power supply 100 supplies electric power from the electric equipment On the other hand, when the outlet portion 100a of the auxiliary device of the present invention is not connected to the outlet connected to the electrical equipment, the power supply 100 is not powered.

When the auxiliary device is connected to the outlet, the power supply 100 continuously supplies power to the electrical equipment as the switch is turned on / off by the connection of the power supply 100 to the outlet connected to the electrical equipment. It can be monitored and monitored.

In one example, when the auxiliary device of the present invention has an adapter structure as shown in Fig. 2, it is not connected to the external electric device 1 at the outlet portion 100b to be connected to the external electric device (D) 1 , The auxiliary device of the present invention can be operated only by being connected to the outlet of the electric equipment.

When the auxiliary device of the present invention has an adapter shape as shown in Fig. 2, the portion for outputting the load in Fig. 1 corresponds to the receptacle portion 100b of the adapter, Is applied to the electric device (D) (1).

1, the power supply unit 100 transmits the power supplied from the electrical equipment to the signal conversion unit 300 and drives the signal conversion unit 300 do.

The signal converting unit 300 receives a waveform as a detection value from the detecting unit 200 and converts the waveform into a signal. The waveforms received from the detecting unit 200 are a current waveform and a voltage waveform, and the signal converting unit 300 converts a current waveform and a voltage And converts the waveform into a discrete signal.

The detector 200 may include a current transformer 210, a potential transformer 220, and a ZCT 230. The current transformer 210 may include a transformer 210, The transformer 220 and the video transformer 230 convert the voltage of the power source inputted to the auxiliary device to detect the voltage waveform and convert the voltage of the power source (300).

The power source to which the current transformer 210, the transformer 220, and the image transformer 230 receive the current waveform or the voltage waveform is a power source for the electrical equipment connected through the plug portion 100a.

The determination unit 400 determines a signal related to the current waveform and the voltage waveform received from the signal conversion unit 300.

The determination unit 400 includes an arc fault determination unit 410, a leakage determination unit 420, and a load type determination unit 430. The current waveform and the voltage waveform arc received from the signal conversion unit 300, Judge failure or short circuit or determine load type.

The arc failure determination unit 410 analyzes a signal related to the current waveform transmitted from the signal conversion unit 300 to determine whether an arc failure occurs.

The leakage determining unit 420 analyzes a signal related to the current waveform transmitted from the signal converting unit 300 to determine a short circuit.

More specifically, the current waveform received from the signal transforming unit 300 by the earth leakage judging unit 420 is a current waveform converted by the signal transforming unit 300 from the image transformer 230.

The load type determination unit 430 determines the type of the load using the signal related to the current waveform received from the signal conversion unit 300 and the signal related to the voltage waveform.

The operations of the arc failure determination unit 410, the leakage determination unit 420, and the load type determination unit 430 are well known in the art, and therefore, the operation principle of each component will not be described in detail in this specification.

Accordingly, the determination unit 400 outputs the arc fault, the leakage current, and the load type determination result to the communication unit 500 or the display unit 600, respectively.

The communication unit 500 is connected to the object Internet network through wired or wireless communication, and transmits the arc fault, short circuit and load type determination result received from the determination unit 400 to the object Internet network as processing data, And transmits a value related to the converted current waveform and the voltage waveform in the unit 300 as raw data to the object Internet network.

For example, the communication unit 500 may be a wired communication module that connects to the object Internet network via Ethernet or serial.

Alternatively, the communication unit 500 may be a wireless communication module that connects to the object Internet network through Zigbee, Bluetooth or Wi-Fi.

Since the communication unit 500 has a structure for connecting to the object Internet network, the auxiliary device of the present invention can transmit the status of the connected electric equipment and the result of the determination to the object Internet network.

The communication unit 500 transmits the control signal received from the object Internet network and the determination result received from the determination unit 400 to the control unit 700 .

The control unit 700 controls the relay 800 according to the determination result of the determination unit 400 transmitted through the communication unit 500 so that the power input from the electric equipment is transmitted to the external electric device D 1 ).

For example, when it is determined that an arc failure has occurred in the arc failure determination unit 410 of the determination unit 400 or that a short circuit has occurred in the leakage determination unit 420, the controller 700 determines that the relay 800 (D) 1, and transmits the determination result to an upper control unit to utilize the result of the determination to determine whether the circuit breaker is tripped. In more detail, The control unit of the control unit 700 judges that there is a short circuit or an arc fault according to the judgment result received from the controller 700 and controls the trip of the circuit breaker.

If the load type determining unit 430 of the determining unit 400 determines that the type of the load is a specific load, the controller 700 transmits a control signal to the relay 800 according to the determination result, (D) (1), and transmits the judgment result to the higher-level control unit so that the power can be cut off in order of the load equipment having less importance in power peak control.

For example, when the determination unit 400 determines a load related to an arc fault, the determination unit 400 determines that the current waveform detected by the current transformer 210 includes an arc-shaped distortion, .

At this time, in a complex load environment in which a waveform similar to an arc fault waveform that interferes with an arc fault determination is generated, a load or a load group that interferes with an arc fault determination is excluded from an arc fault determination and trips the breaker in a steady state environment It is a good idea to minimize errors.

At this time, it is preferable that the load or the load group that interferes with the arc fault judgment is excluded by recognizing in advance a load or a load group that can be judged as an arc fault in a normal state.

More specifically, when an upper control unit performs peak power control, the load type is analyzed according to the determination result received from the control unit 700, the importance of the load is determined through the analyzed load type, Off of the load equipment can be controlled.

In this way, the controller 700 controls the relay 800 according to the determination result of the determination unit 400 to control the load transfer to the external electric device (D) 1, It is possible to prevent the problematic power source from being transmitted to the external electrical device (D) (1), and to prevent the failure of the electrical device by receiving the abnormal power source.

The control unit 700 can control the relay 800 according to a control signal received from the object Internet network through the communication unit 500. [

For example, when the communication unit 500 receives the ON / OFF control signal of the external electric device (D) 1 through the object Internet network, the control unit 700 receives the ON / OFF control signal, Off of the electric device (D) (1).

At this time, the communication unit 500 can receive a control signal for changing the driving state in addition to the ON / OFF control signal of the external electric device (D) 1 through the object Internet network, It is possible to control the relay 800 so as to control the load applied to the relay 1.

At this time, when the control unit 700 controls the external electric device (D) (1) according to the control signal of the external electric device (D) 1 received by the communication unit 500 through the object Internet network, The control unit 700 can only control the external electric device D 1 connected to the auxiliary device in which the corresponding control unit 700 is formed. It is preferable to form the identification numbers of the devices and to control the external electric devices (D) 1 connected to the respective auxiliary devices.

More specifically, when there are two external electric devices D1 and D2, the communication unit 500 formed in the auxiliary device connected to one external electric device D1 and the external device D1, When the control signal received from the Internet network is a signal for controlling another external electric appliance (D2) (1b), the controller (700) of the auxiliary device connected to the electric appliance (D1) The control operation according to the signal is not performed.

On the other hand, when a signal for controlling the electric device D2 (1b) is received from the object Internet network, the communication unit 500 formed in the auxiliary device connected to the other electric device (D2) The control unit 700 of the auxiliary device connected to the electric device D2 1b performs a control operation in accordance with the received control signal.

When a plurality of external electric devices (D) 1 are formed and the auxiliary device of the present invention is connected to a plurality of external electric devices (D) (1), a single external Even if a control signal for controlling the electric device D 1 of each auxiliary device is input to the control unit 700 of all the auxiliary devices through the communication unit 500 of all the auxiliary devices, The control unit 700 determines whether the electric device is identical to the electric device to which the auxiliary device having the corresponding control unit 700 is connected to perform the control operation. To this end, the auxiliary device and the external electric device each include an identification number, It is good to know this in advance.

The display unit 600 may output the determination result of the determination unit 400 received from the communication unit 500 as an output value in digital form or may output a warning sound or the like depending on the determination result of the determination unit 400, It can be displayed in flashing form.

In other words, the display unit 600 may display the result of control according to the control signal of the external electric device D (1) received from the controller 700, that is, the on / off control of the external electric device (D) Can be displayed.

The display unit 600 is formed on the surface of an auxiliary device formed in the form of an adapter to output a current value or a voltage value as a digital power state, thereby facilitating monitoring.

As described above, the relay 800 is formed before the electric power input from the electric equipment is transmitted to the external electric device (D) 1 as a load, And controls the load transfer to the electric device (D) (1).

As the auxiliary device of the present invention has such a structure, it is possible to connect external electric devices (D) 1, which are general devices that can not connect to the object Internet network, to the object Internet network.

Thus, even if an external design of the external electric device (D) 1 is not designed for connection to the object Internet network, the on / off control of the electric device or the abnormal state of the power applied thereto through the adapter- It is possible to easily control and monitor through the network, thereby reducing the design cost of the electric device and increasing the efficiency of monitoring the electric equipment in the home.

In another example, an auxiliary device for connecting to an object Internet network according to an embodiment of the present invention may be formed in the form of an outlet so that an external electric device (D) 1 may be installed at a portion connected to the electric device, As described above with reference to FIG. 1, the electric equipment analyzes power waveform or voltage waveform inputted to the external electric device (D) 1 and transmits the result or raw data to the object Internet network.
