Here, the first connector 100 and the second connector 200 may be detachable male and female receptacles.

1, the first connector 100 includes a first body 110, a first permanent magnet 120, a first contact 130, an electromagnet 140, a sensor unit 150, And a control unit 160.

The first body 110 is made of a material such as an insulator.

The first permanent magnet 120 may be provided in the first body 110 or in a groove formed on one side of the first body 110.

Further, the first permanent magnet 120 has a preset polarity (for example, S pole).

The first contact 130 is formed on one side of the first body 110.

The first contact 130 operates based on the power supplied by the control unit 160.

The electromagnet 140 is operated under the control of the controller 160 by receiving power from a power supply unit (not shown) connected to the first connector 100.

That is, when the first connector 100 and the second connector 200 in the coupled state are separated from each other, the electromagnet 140 operates on the basis of the power supplied by the control of the controller 160. At this time, the electromagnet 140 operates in a polarity opposite to that of the first permanent magnet 120. Here, the electromagnet 140 may be configured to be adjacent to the first permanent magnet 120 in order to operate in a direction opposite to that of the first permanent magnet 120 to weaken the polarity of the first permanent magnet 120.

The sensor unit 150 measures the induced current with respect to the first connector 100 (or around the first connector 100).

 The controller 160 executes the overall control function of the first connector 100. [

In addition, the controller 160 executes the overall control function of the first connector 100 using the program and data stored in the storage unit (not shown). The control unit 160 may include a RAM, a ROM, a CPU, a GPU, and a bus, and the RAM, the ROM, the CPU, and the GPU may be connected to each other via a bus. The CPU accesses the storage unit, performs booting using the O / S stored in the storage unit, and can perform various operations using various programs, contents, and data stored in the storage unit.

The control unit 160 determines whether or not the first connector 100 and the second connector 200 are connected or disconnected based on the induced current measured through the sensor unit 150.

That is, the control unit 160 determines whether the induced current measured through the sensor unit 150 is in a predetermined induction current range in a state where the coupling (or connection) between the first connector 100 and the second connector 200 is engaged , It is confirmed in which range among the predetermined current range in which the coupling (or connection) is not engaged.

The control unit 160 determines whether the first connector 100 and the second connector 200 are disconnected based on the change in the induced current measured through the sensor unit 150.

That is, the control unit 160 determines whether the change (or the amount of change / rate of change) of the induced current measured through the sensor unit 150 is within the range of the induced current in the state where the first connector 100 is separated from the second connector 200 (Or change amount / rate of change) of the induced current measured through the sensor unit 150 is determined by whether the first connector 100 is connected to the second connector 200, The first connector 100 is connected to the second connector 200 by confirming whether or not the current is changed to the induction current range in the state of being separated from the second connector 200 in the induction current range in the state of being coupled with the connector 200, Is in a state of being coupled with or disconnected from the system.

When the first connector 100 and the second connector 200 are coupled to each other, the controller 160 determines whether the first connector 100 and the second connector 200 are connected to the first connector 100 and the second connector 200, Power is not applied to the electromagnet 140 included in the first connector 100 so that the coupling is maintained by the attractive force (or magnetic force) between the permanent magnets.

That is, the determination result (or the determination result) indicates that the induction current measured through the sensor unit 150 is a predetermined induction in the state where the coupling (or connection) between the first connector 100 and the second connector 200 is engaged The controller 160 controls the electromagnet 140 such that current is applied to the electromagnet 140 such that coupling is maintained between the permanent magnets included in the first connector 100 and the permanent magnet included in the second connector 200, .

The controller 160 controls the first connector 130 and the second connector 200 included in the first connector 100 so that the first connector 100 and the second connector 200 are connected to each other. And the power is applied so that the included second contact 230 is kept electrically connected.

In the case where the first connector 100 is coupled with the second connector 200 based on the result of the check (or the determination result) and the change in the induced current measured through the sensor unit 150 The controller 160 controls the first connector 100 and the second connector 200 so that the current flows from the first connector 100 to the second connector 200, Power is not applied to the electromagnet 140 included in the first connector 100 so that the coupling is maintained by the attractive force (or magnetic force) between the permanent magnets included in the first connector 100 and the second connector 200, respectively.

The control unit 160 applies power to the first contact 130 so that the first contact 130 and the second contact 230 are electrically connected.

In addition, the confirmation result (or the determination result) may indicate that the induced current measured through the sensor unit 150 is not set in advance in a state in which the coupling (or connection) between the first connector 100 and the second connector 200 is not engaged The controller 160 controls the electromagnet 140 so that no current flows, and does not apply power to the first contact 130. In this case,

When the first connector 100 and the second connector 200 are separated from each other, the controller 160 controls the first permanent magnets 120 included in the first connector 100 So that the coupling force between the first connector 100 and the second connector 200 is weakened to be easily separated.

That is, when the controller 160 determines that the induced current measured based on the change in the induced current measured through the sensor unit 150 is in a state in which the first connector 100 and the second connector 200 are coupled, The electromagnet 140 is operated with the polarity opposite to that of the first permanent magnet 120 included in the first connector 100 when the induced current is separated from the current.

The first connector 100 and the second connector 200 are separated from each other so that the controller 160 is included in the first contact 130 and the second connector 200 included in the first connector 100 (Or disconnects the power to the first contact 130) to maintain the electrically disconnected state.

1, the second connector 200 includes a second body 210, a second permanent magnet 220, and a second contact 230.

The second body 210 is made of a material such as an insulator.

The second permanent magnet 220 may be provided in the second body 210 or may be provided in a groove formed on one side of the second body 210.

The second permanent magnet 220 has an opposite polarity (for example, N pole) to the first permanent magnet 120 included in the first connector 100.

Accordingly, when the first connector 100 and the second connector 200 are maintained in a combined state, the first permanent magnet 120 and the second connector 200 included in the first connector 100 are included. (Or magnetic force) acts between the first permanent magnets 120 and the second permanent magnets 220 as the second permanent magnets 220 having the opposite polarities to each other, .

It is also possible to easily maintain the coupling between the first connector 100 and the second connector 200 by simply fitting the first connector 100 and the second connector 200 into each other so that a non-skilled person or an automation device (including a drones, a robot, It is possible to attach / detach the first connector 100 and the second connector 200 through the first connector 100 and the second connector 200, respectively.

The second contact 230 is formed on one side of the second body 210. At this time, when the second connector 200 is coupled with the first connector 100, the second contact 230 may be positioned (or fixed) in contact with the first contact 130.

That is, the second contact 230 is configured to face (or face) the first contact 130.

Also, while the first connector 100 and the second connector 200 are maintained in the engaged state, the second contact 230 maintains an electrically coupled state with the first contact 130.

While the first connector 100 and the second connector 200 are maintained in the engaged state, the entire circuit (or system) (not shown) including the first connector 100 and the second connector 200 Power is applied to the first connector 100 and the second connector 200 while the first connector 100 and the second connector 200 are separated from each other, (The first connector 100 / the second connector 200) is cut off, thereby preventing an accident such as an electric shock.

As described above, the engagement is maintained by the attraction force between the permanent magnets of both the first connector and the second connector, and the electromagnet provided in the connector of either the first connector or the second connector when the first connector and the second connector are separated The magnetic forces of the permanent magnets provided on both the first connector and the second connector are canceled to weaken the coupling.

In this way, the coupling state between the connectors can be confirmed by measuring the induced current of the electromagnet.

Hereinafter, a method of controlling a connector that is detachably attached by a magnetic force according to the present invention will be described in detail with reference to FIGS. 1 to 4. FIG.

FIG. 2 is a flowchart illustrating a method of controlling a connector that is detachably attached to a connector according to an embodiment of the present invention.

First, the sensor unit 150 included in the first connector 100 measures the induced current with respect to the first connector 100 (or around the first connector 100).

3, in a state where the first connector 100 is not engaged with the second connector 200, the sensor unit 150 can sense the first induced current around the first connector 100 .

4, in a state in which the first connector 100 is coupled to the second connector 200, the sensor unit 150 detects the second induced current around the first connector 100 .

As another example, in a state where the first connector 100 is separated from the second connector 200 or the first connector 100 is in engagement with the second connector 200, The third induced current around the connector 100 is measured (S210).

The control unit 160 included in the first connector 100 determines whether the first connector 100 and the second connector 200 are coupled or disconnected based on the induced current measured through the sensor unit 150 Confirm (or judge).

That is, the control unit 160 determines whether the induced current measured through the sensor unit 150 is in a predetermined induction current range in a state where the coupling (or connection) between the first connector 100 and the second connector 200 is engaged , It is confirmed in which range among the predetermined current range in which the coupling (or connection) is not engaged.

The control unit 160 determines whether the first connector 100 and the second connector 200 are disconnected based on the change in the induced current measured through the sensor unit 150.

That is, the control unit 160 determines whether the change (or the amount of change / rate of change) of the induced current measured through the sensor unit 150 is within the range of the induced current in the state where the first connector 100 is separated from the second connector 200 (Or change amount / rate of change) of the induced current measured through the sensor unit 150 is determined by whether the first connector 100 is connected to the second connector 200, The first connector 100 is connected to the second connector 200 by confirming whether or not the current is changed to the induction current range in the state of being separated from the second connector 200 in the induction current range in the state of being coupled with the connector 200, Is in a state of being coupled with or disconnected from the system.

For example, the controller 160 may determine that the first induced current measured through the sensor unit 150 is within a predetermined eleventh induced current range in a state where the coupling between the first connector 100 and the second connector 200 is engaged And the predetermined twelfth induced current range in the state where the coupling is not engaged.

The controller 160 may determine that the second induction current measured through the sensor unit 150 is equal to or greater than a predetermined eleventh induction current in the state where the coupling between the first connector 100 and the second connector 200 is engaged, Range and the predetermined twelfth induced current range in the state where the coupling is not engaged are confirmed.

In another example, the controller 160 determines whether the first connector 100 and the second connector 200 are separated based on a change in the third induced current that is continuously measured through the sensor unit 150 S220).

When the first connector 100 and the second connector 200 are coupled to each other, the controller 160 determines whether the first connector 100 and the second connector 200 are connected to the first connector 100 and the second connector 200, Power is not applied to the electromagnet 140 included in the first connector 100 so that the coupling is maintained by the attractive force (or magnetic force) between the permanent magnets.

That is, the determination result (or the determination result) indicates that the induction current measured through the sensor unit 150 is a predetermined induction in the state where the coupling (or connection) between the first connector 100 and the second connector 200 is engaged The controller 160 controls the electromagnet 140 such that current is applied to the electromagnet 140 such that coupling is maintained between the permanent magnets included in the first connector 100 and the permanent magnet included in the second connector 200, .

In addition, since the first connector 100 and the second connector 200 are held in engagement, the first contact 130 included in the first connector 100 and the second contact 200 included in the second connector 200, (230) are maintained in an electrically connected state.

For example, when the second induced current measured through the sensor unit 150 is included in a predetermined eleventh induced current range in a state where the coupling between the first connector 100 and the second connector 200 is engaged, (160) does not apply power to the electromagnet (140).

The control unit 160 applies power to the first contact 130 so that the first contact 130 and the second contact 230 are electrically connected.

The control unit 160 determines that the first connector 100 and the second connector 200 are coupled based on the change in the third induced current that is continuously measured through the sensor unit 150. In other words, The first contact 130 and the second contact 230 are electrically connected to each other after the first connector 100 and the second connector 200 are coupled to each other. 1 contact 130 in step S230.

When the first connector 100 and the second connector 200 are separated from each other, the controller 160 controls the first permanent magnets 120 included in the first connector 100 So that the coupling force between the first connector 100 and the second connector 200 is weakened to be easily separated.

That is, when the controller 160 determines that the induced current measured based on the change in the induced current measured through the sensor unit 150 is in a state in which the first connector 100 and the second connector 200 are coupled, The electromagnet 140 is operated with the polarity opposite to that of the first permanent magnet 120 included in the first connector 100 when the induced current is separated from the current.

The first connector 100 and the second connector 200 are separated from each other so that the controller 160 is included in the first contact 130 and the second connector 200 included in the first connector 100 (Or disconnects the power to the first contact 130) to maintain the electrically disconnected state.

For example, when it is determined that the first connector 100 and the second connector 200 are being separated based on the change in the third induced current, which is continuously measured through the sensor unit 150, The electromagnet 140 is operated in an opposite polarity (for example, N pole) to the first permanent magnet 120 (for example, the S pole) included in the first connector 100.

In addition, the confirmation result (or the determination result) may indicate that the induced current measured through the sensor unit 150 is not set in advance in a state in which the coupling (or connection) between the first connector 100 and the second connector 200 is not engaged (Or when the first connector 100 and the second connector 200 have attempted to be separated and the separation is completed), the electric current flows to the electromagnet 140) And does not apply power to the first contact 130.

In another example, when the first induced current measured through the sensor unit 150 is included in a predetermined twelfth induction current range in a state where the coupling between the first connector 100 and the second connector 200 is not engaged , The controller 160 does not apply power to the electromagnet 140 (S240).

As described above, in the embodiment of the present invention, the engagement is maintained by the attraction force between the permanent magnets of both the first connector and the second connector, and the engagement of the first connector and the second connector The magnetic forces of the permanent magnets provided on both the first connector and the second connector are canceled by weakening the magnetic forces of the permanent magnets provided on both the first connector and the second connector by using the electromagnets provided in the one connector and the unmanned aerial vehicle loads a substitute You can easily replace it with a replacement by just going and lifting or lowering the device.
