FIG.

Referring to FIG. 3, the rail control module 300 includes a direction indicator signal detector 310, a driver 320, and a controller 330.

The direction indicating signal detecting unit 310 detects the direction in which the electric unit 150 moves in the longitudinal direction of the rail 110.

Here, the direction indicating signal is a signal indicating in advance the direction in which the electric unit 150 moves, and may be a signal indicating a direction in which a specific signal (for example, light using a light emitting element or a magnetic force using an electromagnet, So as to inform the moving direction.

The direction indicating signal detecting unit 310 detects a direction indicating signal indicating a moving direction of the electric unit 150 by using a specific signal (e.g., a signal using light or a magnetic force) from the electric unit 150 (E.g., a light detection sensor, a hall sensor, and the like). At least one sensor (not shown) is installed in the longitudinal direction of the rail 110.

The reason why the direction indicating signal is detected in advance is that the electromagnet of the radial magnetic portion 230 is moved in accordance with the position of the electromagnets 281 and 282 of the unit magnetic portion 280 to move the electric unit 150 231, 232), thereby generating attractive force and repulsive force (see FIG. 6).

The remote control signal is received from the remote control device (or wired / wireless transmitter).

The remote control device (particularly, the wireless transmitter) may be an RF transmitter using an RF (Radio Frequency) signal (e.g., WiFi, 3G, 4G or LTE), an infrared transmitter using an infrared signal, a Bluetooth, a Zigbee And a short-range wireless transmitter using a short-range communication signal.

The direction indicating signal output unit 420 outputs a direction indicating signal indicating the direction in which the electric unit 150 is moved according to the control of the controller 440.

The direction indicating signal output unit 420 is installed at the front (or front bottom) or rear (or rear bottom) of the electric unit 150 (see FIG. 6).

For example, when the electric unit 150 is to be moved forward, a direction indicating signal output unit 520 installed in front is driven to output a direction indicating signal. When the electric unit 150 is moved backward, And drives the installed direction instruction signal output unit 520 to output the direction instruction signal.

The direction indicating signal is a signal indicating in advance the direction in which the electric unit 150 is to be moved. The direction indicating signal is a signal indicating a direction in which the electric unit 150 moves, for example, by using a specific signal (e.g., a signal using light using a light emitting element or a magnetic force using an electromagnet, And output it.

The driving unit 430 may control the electromagnets 281 and 282 of the unit magnetic unit 280 in accordance with the positions of the electromagnets 231 and 232 of the radial magnetic unit 230 under the control of the controller 440. [ Respectively.

The controller 440 processes the remote control signal to determine a moving direction (i.e., forward / backward) of the electric unit 150 desired by the user. The polarities of the electromagnets 281 and 282 of the unit magnetic portion 280 are changed through the driving portion 430 in order to move the electric unit 150 in the determined movement direction.

The electromagnets 281 and 282 of the unit magnetic portion 280 located behind the electromagnets 231 and 232 of the radial magnetic portion 230 with respect to the direction in which the electric unit 150 is advanced, Of the electromagnets (231, 232) of the unit magnetic portion (280) at the position before the electromagnets (231, 232) of the radial magnetic portion (230) 281, and 282 are controlled so as to have the same polarity, and are moved in the advancing direction by the repulsive force, thereby moving the electric unit 150 (see FIG. 6).

The control unit 330 of the rail control module 300 processes the detected direction indicating signal to determine the direction in which the electric unit 150 moves (S105).

The control unit 330 of the rail control module 300 drives the rail unit 230 in a predetermined pattern (or a timing pattern) according to the direction in which the determined electric unit 150 moves (S106) . That is, the polarities of the electromagnets 231 and 232 of the radial magnetic portion 230 are changed corresponding to the direction in which the electric unit 150 is advanced.

The control unit 440 of the unit control module unit 400 drives the unit magnetic unit 280 in a predetermined pattern (or a timing pattern) according to the direction in which the electric unit 150 is moved (S107). That is, the polarities of the electromagnets 281 and 282 of the unit magnetic portion 280 are changed in accordance with the direction in which the electric unit 150 is advanced.

If the radome 230 or the unit magnetic portion 280 is not driven, the movement of the electric unit 150 can be stopped or restrained.

The control unit 330 of the rail control module unit 300 or the control unit 440 of the unit control module unit 400 may control the operation of the control unit 440 in the case where the remote control signal is a signal for stopping the movement of the electric unit 150. [ It is possible to stop the movement of the electric unit 150 by stopping the driving of the radial magnetic portion 230 or the unit magnetic portion 280 (that is, by maintaining the polarity of the electromagnet unchanged). At this time, the electric unit 150 may be constrained by maintaining the polarity of the electromagnet.

And stopping the movement of the electric unit by maintaining the polarities of the electromagnets provided on the rail or the electric unit according to the remote control signal without changing the polarity of the electromagnets.
12. The method of claim 11,
Further comprising: remotely controlling at least one of a brightness, a color, and a point-by-point mode of illumination provided in the electric unit according to the remote control signal.
12. The method of claim 11,
Wherein the step of changing polarities of the electromagnets provided on the rail includes:
Wherein the control unit controls the electromagnet of the reamer at a position before the electromagnet of the electric unit with respect to the advancing direction of the electric unit to have an opposite polarity, Wherein the control unit controls the electromagnets of the first and second electromagnets to have the same polarity.
12. The method of claim 11,
Wherein changing the polarity of the electromagnets provided in the electric unit comprises:
The control unit controls the electromagnet of the electric unit at a position before the electromagnet of the ream unit to have the same polarity with respect to the advancing direction of the electric unit, Wherein the control unit controls the electromagnet of the movable illumination device to have the opposite polarity.
