1 is a block diagram illustrating a configuration of an electronic receptacle for supporting media playback according to the first embodiment of the present invention.

Referring to FIG. 1, an electronic socket for supporting media playback according to the present invention includes a safety receptacle 10, a wired / wireless charger 20, a media player 30, and a controller 40.

The safety receptacle 10 is provided with a cut-off switch 11 for shutting off the input power at the time of the on-operation. The safety receptacle 10 includes at least one of the current value, the voltage value, the resistance value, the resonance value and the frequency measured at the output terminal of the cut- And performs an input power cutoff function of the cutoff switching (11) by using one of them.

The shutdown switch 11 provided in the safety receptacle 10 draws the input power supplied from the distribution board 1 through the output terminal or cuts off the power applied from the distribution board 1 under the control of the control unit 40. It is preferable that the switching of the cut-off switch 11 cuts off the input power in the ON operation.

The safety receptacle 10 may have various circuits for measuring at least one of a current value, a voltage value, a resistance value, a resonance value and a frequency at an output terminal of the cut-off switch 11. [ More specifically, the safety receptacle 10 includes a current measuring circuit 12 for measuring a current value, a voltage measuring circuit 13 for measuring a voltage value, a resistance measuring circuit 14 for measuring a resistance value, And a resonance circuit 15 for measuring a resonance value or frequency including an inductance and a capacitance component.

The safety receptacle 10 is configured such that at least one of the current value, the voltage value, the resistance value, the resonance value and the frequency measured by the above-described circuits 12 to 15 at the output terminal of the cut- The shut-off switch 11 is turned on as it is detected in a range of values corresponding to one of the contact state, the standby power state, and the overload state. In particular, the safety receptacle 10 can turn the operation of the disconnecting switch 11 on or off under the control of the control unit 40. [

The circuits 12 to 15 provided in the safety receptacle 10 are connected to the two wires of the output terminal of the cut-off switch 11 in consideration that the indoor or outdoor power line is a double line consisting of two wires . However, the circuits 12 to 15 provided in the safety receptacle 10 may be connected to only one of the two wires of the output terminal of the cut-off switch 11.

The control unit 40 senses the state of the output terminal of the cutoff switch 11 on the basis of the values measured by the circuits 12 to 15 provided in the safety receptacle 10, And outputs a control signal for controlling switching to the safety receptacle 10.

The control unit 40 senses the power line state from the output terminal of the cutoff switch 11 to the socket 50 by using the measurement value inputted from the circuits 12 to 15 provided in the safety receptacle 10.

The control unit 40 divides the state of the output terminal of the cut-off switch 11 into a human body contact state, a conductor contact state, a standby power state, and an overload state, and calculates a current value, a voltage value, a resistance value, a resonance value, define. Accordingly, the control unit 40 detects the steady state and the abnormal state according to whether the input measured value belongs to the range of the reference value defined for each state, and if the detection result is determined to be abnormal, A control signal for controlling switching (on or off) of the switch 11 is applied to the safety receptacle 10 and the cutoff switch 11 is turned on to automatically cut off the input power applied from the distribution board 1. Here, the steady state is a state in which an electronic device or an electric device is normally connected or the devices are normally operated after being connected, and an abnormal state is a human contact state, a conductor contact state, a standby power state, and an overcurrent state or an overcurrent state. The human body contact state is a state in which a living body such as a person or an animal is in direct contact with the output terminal of the cut-off switch 11, and the conductor contact state is a state in which an object such as metal is inserted into the output terminal of the cut- .

The control unit 40 controls at least one of the current value, the voltage value, the resistance value, the resonance value and the frequency measured by the circuits 12 to 15 at the output terminal of the shut-off switch to be in a human contact state, The range of the voltage value, the range of the resistance value, and the range of the current value corresponding to the human body contact state, the conductor contact state, the standby power state and the overload state, respectively, And a memory for storing a range of a resonance value and a frequency range. Here, the memory is provided inside the control unit 40 and is not separately shown.

That is, the memory provided in the control unit 40 distinguishes between a human body contact state, a conductor contact state, a standby power state, and an overload state, and determines a range of a current value used as a criterion for detecting each state, Range and range of resistance value and resonance value range and frequency range are stored.

Accordingly, the control unit 40 compares at least one of the current value, the voltage value, the resistance value, the resonance value and the frequency inputted from the circuits 12 to 15 with the range value of each state stored in the memory, The state of the output terminal of the cutoff switch 11 is detected as a normal state or an abnormal state corresponding to one of a human body contact state, a conductor contact state, a standby power state and an overload state is detected.

The control unit 40 applies a control signal to turn on the shutdown switch 11 to the safety receptacle 10 to automatically shut off the input power applied from the distribution board 1 .

As another example, the control unit 40 detects the state of the output terminal of the cut-off switch 11 based on the current value, the voltage value, the resistance value, the resonance value, and the frequency when the electronic apparatus or the electric apparatus normally operates. . For this purpose, the control unit 40 has information on the current value, the voltage value, the resistance value, the resonance value, and the frequency when operating in a normal connection state for each device, It can be used as a reference value for detection.

In addition, the controller 40 has information on the current value, the voltage value, the resistance value, the resonance value and the frequency when the device is in a steady state for each device. It holds information about the range in which the value and frequency change. For example, if the resistance value exceeds + 1? At the steady state of the A device, the control section 40 detects the abnormal state.

The socket 50 is a mechanical means electrically connected to the output terminal of the cut-off switch 11, and is a means for mechanically inserting a plug provided in an electronic device or an electric device.

As another example, the control unit 40 may support the manual switching operation in addition to the operation of sensing the state of the output terminal of the disconnecting switch 11 and automatically switching the disconnecting switch 11 accordingly. That is, when an input signal requesting forcible driving of the shutoff switch 11 is applied through the external input means, the control unit 40 controls the shutoff switch 11 in response to the input signal, 11 is kept in the OFF state or the ON state in which the input power is cut off is switched to the OFF state. This is in contrast to the case where the state of the output terminal of the cut-off switch 11 is misunderstood in accordance with the value measured in the circuits 12 to 15 indicating the abnormal state despite the normal connection state of the electronic appliance or the electric appliance .
