In this case, the electromagnetic compatibility measurement is performed once in a vertical state in which the antenna is disposed in a vertical direction on the ground, and once again in a horizontal state in which the antenna is disposed in a horizontal direction on the ground.

That is, when the antenna transfer device 300 stops at the measurement position and performs electromagnetic compatibility measurement using an antenna in a vertical state, the control means 330 controls the antenna rotation means 360 to rotate the antenna in a horizontal state. do.

The antenna rotation means 360 applies power to a rotation shaft on which the antenna is mounted to rotate the antenna by a predetermined angle, and the antenna rotation motor 361 applies power to the rotation shaft on which the antenna is installed, and the control means 330 It may be configured to include an antenna rotation driver 362 that turns on and off the antenna rotation motor 361 or controls the rotation speed or rotation direction according to the control.

Here, the antenna rotation driver 362 operates the antenna rotation motor 361 under the control of the control means 330, so that the vertical antenna may be rotated in a horizontal state. Then, when the electromagnetic compatibility measurement using the horizontal antenna is completed, the control means 330 controls the antenna rotation driver 362 to operate the antenna rotation motor 361 again, thereby bringing the horizontal antenna back to the vertical state. You can also rotate it.

At this time, the control means 330 may control the antenna rotation driver 362 and the antenna rotation motor 361 based on information sensed from the above-described photosensor 352.

On the other hand, since unintended noise may be generated by the power supply means 310, the driving means 340, and the antenna rotating means 360, etc., when measuring electromagnetic compatibility, the control means 330 uses the blocking means 370. By controlling the commercial power supplied to the power supply means 310 can be cut off.

The blocking means 370 is for cutting off the supply of commercial power when measuring electromagnetic compatibility, and commercial power is supplied to the power supply means 310, in particular, the second power supply 312 according to the control of the control means 330. It performs the function of blocking so that it is not supplied.

Such, the blocking means 370 is disposed between the relay 371 turned on and off according to the control of the control means 330, the output end of the noise filter 305 and the ì�� power end of the second power supply 312, and relay ��´ 371 It may be configured to include an electromagnetic contactor 372 that is turned on and off by power applied from).

That is, when the relay 371 is turned off by the control means 330, the power applied to the magnetic contactor 372 from the relay 371 is cut off, and the magnetic contactor 372 is turned off, and the magnetic contactor 372 is turned off. As a result, commercial power to be input to the second power supply 312 is cut off. Accordingly, the driving power of the second power supply 312 is not supplied to the driving means 340 and the antenna rotating means 360.

On the other hand, when the electromagnetic compatibility measurement is completed, the relay 371 is turned on by the control means 330, the electromagnetic contactor 372 is turned on, and commercial power may be supplied to the second power supply 312.

In addition, the control means 330 controls the driving means 340 to move the antenna transfer device 300, and the antenna transfer device 300 moves along the rail unit 100 to the initial starting position or the measurement end position. When the installed position display unit 200 is sensed, it is determined that the measurement of electromagnetic compatibility of the antenna transfer device 300 has been completed, and the driving means 340 may be stopped.

When the position display unit installed at the position is sensed, the control unit may control the driving unit to stop at the measurement position (S120).

In addition, a plurality of the above-described measurement locations may be provided, and a measurement location at which each antenna transfer device should be stopped may be preset in the main control unit according to the type of antenna or antenna frequency. That is, the main control unit controls each antenna transfer device to perform electromagnetic compatibility measurement at a preset measurement position.

Then, the main control unit controls the antenna transfer device stopped at the measurement position to perform electromagnetic compatibility measurement in which electromagnetic waves are emitted or collected through the mounted antenna (S200).

In addition, when measuring electromagnetic compatibility, the antenna transfer device rotates the axis of rotation on which the antenna is mounted under the control of the main control unit, so that the antenna disposed vertically on the ground becomes a horizontal direction or the antenna disposed horizontally on the ground becomes a vertical direction. It may be provided to be oriented and then start the electromagnetic compatibility measurement.

At this time, the antenna transfer device may rotate the antenna by a predetermined angle by applying power to the rotation shaft on which the antenna rotation means is mounted under the control of the control means before or after the electromagnetic compatibility measurement.

It can be equipped with.

In addition, the vertical state or the horizontal state of the antenna may be sensed through the sensing means, and for this purpose, the sensing means may include a photo sensor that detects a rotation angle or a slot of a rotating shaft on which the antenna is mounted.

On the other hand, when measuring electromagnetic compatibility, unintended noise may be generated by the power supply means, driving means, and antenna rotation means provided in the antenna transfer device, so when the rotation of the antenna is completed by the antenna rotation means, the control means is a blocking means. It is possible to cut off the commercial power supplied to the power supply means by controlling.

That is, the relay of the blocking means is turned off according to the control of the control means, and the magnetic contactor of the blocking means, which is turned on and off by the power applied from the relay, is turned off, and the commercial power input to the second power supply is cut off. Driving power supplied from the power supply to the driving means and the antenna rotating means can also be cut off.

Next, the main control unit controls the antenna transfer device that has completed the electromagnetic compatibility measurement and moves it along the rail, and when the position indicator installed at the initial starting position or the measurement end position is detected from the antenna transfer device, the antenna transfers to that position. The device is stopped (S300).

At this time, the control means of the antenna transfer device can receive a control command from the main control unit through the communication means, and control the driving means to apply power to the wheels for driving to drive along the rail unit, and then start from the sensing means. When the position indicator installed at the starting position or the measurement end position is sensed, the control means can control the driving means to stop at the measurement position.
