Description

Technical Field

[0001] The present invention relates to the field of automated detection technology, and in particular to a resistance detection mechanism for an array antenna. Background Art

[0002] Array antenna may refer to an arrangement method in array antenna, that is, the antenna units are arranged in a straight line according to a certain rule to form a linear array, also called an array array or a linear array. The radiated electromagnetic field of the array antenna is the sum (vector sum) of the radiation fields of each unit that makes up the antenna array. Since the position of each unit and the amplitude and phase of the feeding current can be adjusted independently, the array antenna has various functions that cannot be achieved by a single antenna. By adjusting the spacing of the array elements, the phase and amplitude of the feeding current and other parameters, the radiation directivity of the array antenna can be controlled to achieve concentrated radiation of energy and high gain; With the development of economy and the progress of society, energy conservation, cost reduction and efficiency improvement have become inevitable and social consensus. Various equipment are increasingly developing towards the characteristics of energy saving, ease of use, safety and efficiency. However, the existing detection method is that workshop workers use handheld multimeters to perform resistance detection, which increases labor and labor costs, and has low work efficiency.

The turntable is connected to the chassis through a rotating shaft and can rotate freely on the chassis. The user can manually operate the turntable to rotate the workpiece placed thereon. The turntable usually has a circular scale. The user can adjust the angle of the workpiece by manually rotating the turntable as needed. This flexibility enables the manual rotating table to adapt to a variety of different work requirements. The turntable and the chassis are usually made of sturdy materials to ensure that they can withstand the weight of the workpiece and the force generated during rotation.
