Description

Adjusting system for automatically adjusting height of antenna support

Technical Field

The utility model relates to an governing system for automatically regulated antenna boom height.

Background

When electromagnetic compatibility radiation emission and radiation sensitivity tests are carried out, the heights of the central positions of the receiving antennas or the transmitting antennas are different due to different detection standards. At present, the receiving antenna or the transmitting antenna bracket in most electromagnetic compatibility laboratories is fixed in height or adjustable in height but needs to be adjusted and determined after the height is measured manually, so that the test efficiency is reduced, and the accuracy of the test result is also reduced. Taking the commonly used detection standards GJB151A/152A-1997 and GJB151B-2013 for military aircraft as examples, when an RE102 electric field radiation emission test is carried out, a 104cm rod antenna is used in a frequency band of 10 KHz-30 MHz, the antenna ground grid is required to be 80-90 cm away from the floor in the GJB151A/152A-1997 standard, and the GJB 151-151B-2013 standard requires that the center point of a rod antenna pull rod is 120cm away from the ground, namely the antenna ground grid is 68cm away from the floor, so that the corresponding antenna height needs to be adjusted according to the standard requirements during the test, and time and labor are wasted.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The present embodiment provides an adjusting system for automatically adjusting the height of an antenna support, which comprises a base 3, a supporting column 2 and a console 1 from bottom to top in sequence as shown in fig. 3. Wherein, the support column adopts a telescopic structure. Referring to fig. 1, the console includes a touch screen, an MCU control board, an ultrasonic distance sensor, and a driver-driven servo motor.

The touch screen is used as a man-machine interaction interface, and the functions of target height input and real-time display of the current height are achieved. The touch screen collects the target height input by the user and inputs the target height into the MCU control panel.

The ultrasonic distance sensor is connected with the antenna, and the height information measured by the ultrasonic distance sensor can be used as the height information of the antenna. The ultrasonic distance sensor collects height information from the ultrasonic distance sensor to the ground and inputs the height information into the MCU control panel.

The MCU control board controls the driver to drive the servo motor according to the difference between the height information and the target height, and the servo motor drives the supporting column to stretch until the height information is consistent with the target height.

The bottom of base 3 is equipped with the universal wheel, can be by operating personnel free movement.

The top of the console 1 is provided with a through hole, and the antenna extends out of the through hole to emit electric field radiation. The radiation process of the antenna emitting the electric field is not related to the present application and will not be described herein.

The adjusting process of the adjusting system for automatically adjusting the height of the antenna bracket is shown in fig. 2, and the main process is summarized as follows:

① when the system is started, the MUC control board reads the current position height L1 fed back by the ultrasonic distance sensor, when L1 meets the use requirement, the operator can close the system to directly carry out the electromagnetic compatibility test;

② when L1 can not meet the use requirement, the operator can input the target height through the touch screen, the height of the supporting column 2 of the antenna bracket is increased when the servo motor moves in the forward direction, and the height of the supporting column 2 of the antenna bracket is decreased when the servo motor moves in the reverse direction;

the ③ MCU control board receives the target height L input by the operator, when the current height L1 is larger than the target height L, it indicates that the current antenna position is higher and the height thereof needs to be reduced, and at this time, the motor is controlled to move in the direction until the target height is met, when the current height is smaller than the target height L, it indicates that the current antenna position is lower and the height thereof needs to be increased, and at this time, the motor is controlled to move in the forward direction until the target height is met.
