Description

technical field [0001] The invention relates to antenna angle detection, in particular to an integrated device for antenna helicoid partition limit and data transmission, which can continuously detect antenna angle and monitor automatic electromechanical limit. Background technique [0002] In radar work, azimuth scanning usually requires the antenna azimuth to move continuously in the same direction over 360°, so mechanisms such as slip rings and speed-increasing gears are often used to form azimuth limit and data feedback devices, but in remote sensing and telemetry antennas and In medium and high-orbit satellite tracking antennas, the azimuth scanning angle is usually within ±360°. In order to ensure the tracking speed of the antenna and the azimuth movement of the antenna are continuous and effective, and various signal and control cables are not entangled, it is usually required that the azimuth of this type of antenna be continuous The movement is within 360°. At this ...

[0002] In radar work, azimuth scanning usually requires the antenna azimuth to move continuously in the same direction over 360°, so mechanisms such as slip rings and speed-increasing gears are often used to form azimuth limit and data feedback devices, but in remote sensing and telemetry antennas and In medium and high-orbit satellite tracking antennas, the azimuth scanning angle is usually within ±360°. In order to ensure the tracking speed of the antenna and the azimuth movement of the antenna are continuous and effective, and various signal and control cables are not entangled, it is usually required that the azimuth of this type of antenna be continuous The movement is within 360°. At this time, the azimuth limit and data feedback are affected by continuous movement and various installation device limits and the volume of feedback components. It is impossible to arrange various components in a plane, so Slip rings are required, but because the signal frequency is too high, the manufacturing cost is too high, and there is also the problem of emission from the position of the limiting device

In order to solve such problems, usually such devices are not only complex and bulky, but also have low partition and limit accuracy, and the upper limit and data feedback devices cannot be integrated
