Antenna detection distance automatic test device

Abstract

The invention provides an antenna detection distance automatic test device which comprises a first horizontal translation device, a second horizontal translation device, a vertical moving device, a third horizontal translation device, a tag attitude adjusting device and a computer. A control board of each drive motor is connected with the computer. The computer is provided with a motor control module which is used for controlling the work of each drive motor, and a calculation module which is used for determining the position of a tag connecting component or a tag on the tag connecting component and the distance with an antenna according to the work of each drive motor. According to the invention, the test device can automatically control antenna and tag movement, antenna spacing, the height of the tag from the ground, the tag detection direction, and the position of the tag from the antenna; the computer can automatically calculate the height of the tag from the ground, the tag detection direction, and the position of the tag from the antenna; the test device can automatically carry out an antenna detection distance test; the antenna detection distance test is simple and easy; and the accuracy is improved.

Description

technical field [0001] The invention relates to antenna detection distance testing equipment. Background technique [0002] The farthest distance that the anti-theft tag can detect on the antenna and trigger the antenna alarm is called the detection distance of the antenna, which is the most important performance index of the antenna. The frequency element inside the anti-theft tag forms invisible magnetic field lines around the tag, and the magnetic flux section is perpendicular to the magnetic field line. When the magnetic flux section of the anti-theft tag is parallel to the antenna facade and perpendicular to the ground, it is called the X detection of the anti-theft tag on the antenna. direction; when the magnetic flux section of the anti-theft label is perpendicular to the antenna facade and the ground at the same time, it is called the Y detection direction of the anti-theft label on the antenna; when the magnetic flux section of the anti-theft label is perpendicular ...
