Problems solved by technology

When conducting electromagnetic compatibility tests, antenna racks are required to carry the antennas, and antennas of different types or different working frequency bands are required for testing in different test frequency bands, and frequent replacement of antennas will cause greater loss to the antenna and waste experiments time
In addition, the electromagnetic compatibility test has strict regulations on the distance between the antenna and the object under test, and the lengths of various antennas are different. After the antenna is replaced, it is often necessary to reposition the antenna. Each time the operator manually positions the antenna, it is prone to positioning problems. Improperly affecting the accuracy of the test

Abstract

The invention provides a translational antenna stand and a control system for automatically replacing antennas. The translational antenna stand for automatic antenna replacement provided by the present invention includes a base, a column, a horizontal driving part, a cross bar, and an antenna, wherein one end of the column is fixed on the base; the horizontal driving part is fixed on the On the column; the cross bar is fixedly connected with the horizontal driving part, and at least one antenna is arranged on the cross bar; the horizontal driving part is used to push the cross bar to move in the horizontal direction, and then adjust the horizontal bar carried the location of the antenna. The translational antenna rack and control system for automatic antenna replacement provided by the present invention have simple working principle, convenient operation and strong reliability, which not only avoids damage to the antenna caused by frequent disassembly and replacement of the antenna, but also prolongs the service life of the antenna; Errors caused by manual repositioning after antenna replacement are avoided, thereby ensuring the accuracy of test results.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility testing, and specifically designs a translational antenna rack and a control system for automatically replacing antennas. Background technique [0002] Commonly used antennas for EMC testing include biconical antennas, log-periodic antennas, and horn antennas. When conducting electromagnetic compatibility tests, antenna racks are required to carry the antennas, and antennas of different types or different working frequency bands are required for testing in different test frequency bands, and frequent replacement of antennas will cause greater loss to the antenna and waste experiments time. In addition, the electromagnetic compatibility test has strict regulations on the distance between the antenna and the object under test, and the lengths of various antennas are different. After the antenna is replaced, it is often necessary to reposition the antenna. Each time the operator manually...
