In addition, the drive driver 342 operates the drive motor 341 under the control of the control means 330, and power is applied to the wheels from the drive motor 341, so that the antenna transfer unit 300 is transferred to the rail unit 100 You can move towards the measurement location along

The sensing means 350 detects the position display unit 200 and the other antenna transfer unit 300, and at the same time performs a function of detecting the vertical state or the horizontal state of the antenna, and controls the information sensed by the sensing means 350 It may be output to the means 330.

Such, the detection means 350 is a position detection sensor 351 for detecting the position display unit 200, a photo sensor 352 for detecting the vertical or horizontal state of the antenna, and for detecting the other antenna transfer unit 300 It may be configured to include a limit sensor 353.

Here, it is preferable that the position detection sensor 351 is provided as a magnetic sensor so as to detect or detect the position display unit 200 provided with a magnet and installed at an initial starting position, a measurement end position, and a measurement position.

In addition, the photo sensor 352 may be provided as a horseshoe sensor, and may be provided to detect whether the antenna is set to a vertical state or a horizontal state by detecting the rotation angle of the rotation shaft on which the antenna is mounted, a slot provided on the rotation shaft, etc. I can.

In addition, the limit sensor 353 may be mounted on the front and rear sides of the antenna transfer unit 300, respectively, and the presence of the other antenna transfer unit 300 in a manner that detects the limit sensor 353 of the other antenna transfer unit 300 Alternatively, it may be provided to detect whether it is adjacent.

In addition, when the antenna transfer unit 300 reaches the measurement position while moving along the rail unit 100 and the position display unit 200 is sensed from the detection unit 350, the control unit 330 operates the driving unit 340. After stopping the movement of the antenna transfer unit 300, the electromagnetic compatibility measurement may be performed.

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 unit 300 stops at the measurement position and performs electromagnetic compatibility measurement using a vertical antenna, the control unit 330 controls the antenna rotation unit 360 to rotate the antenna in a horizontal state. .

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 unit 300, and the antenna transfer unit 300 moves along the rail unit 100 and is then installed at the initial starting position or the measurement end position. When the display unit 200 is sensed, it is determined that the measurement of electromagnetic compatibility of the antenna transfer unit 300 has been completed, and the driving means 340 may be stopped.

Then, the main control unit controls the antenna transfer unit stopped at the measurement position to perform an electromagnetic compatibility measurement for emitting or collecting electromagnetic waves through the mounted antenna (S200).

In addition, when measuring electromagnetic compatibility, the antenna transfer unit rotates the axis of rotation on which the antenna is mounted under the control of the main control unit, so that the antenna placed vertically on the ground becomes a horizontal direction or the antenna placed horizontally on the ground is placed in a vertical direction.
