Embodiment Construction

[0030] See Figure 1a , b: An intelligent three-dimensional programmable antenna reflecting surface of the present invention is composed of a reflecting surface main body and a control system. The relationship between the two is: the control system is placed next to the main body of the reflective surface for control and manipulation, and the interface of the control system and the main interface of the radiating surface are connected by corresponding lines.

[0031] The main body of the reflecting surface is composed of a static platform and a plurality of parallel mechanism modules. Multiple parallel mechanism modules are placed on the static platform. The static platform is a rectangular sheet whose exact size depends on the size of the topological structure. The parallel mechanism module is fixed on the static platform by bolts. Its main body is the topology structure of the parallel mechanism module. The size of the reflective surface can be adjusted by changing the to...

Abstract

The invention relates to an intelligent three-dimensional programmable antenna reflecting surface. The intelligent three-dimensional programmable antenna reflecting surface consists of a reflecting surface main body and a control system, wherein the control system is placed near the reflecting surface main body so as to perform control and operation, and an interface of the control system is connected with an interface of an emitting surface main body through a corresponding line; the reflecting surface main body consists of a static platform and a plurality of parallel connected mechanism modules; the parallel connected mechanism modules are placed on the static platform; the control system consists of a motor servo driver, a motion control card, a sensor receiver, a sensor amplifier, control system software, a micro-computer, a liquid crystal displayer, a monitoring camcorder lens, and a safety guarantee system; the micro-computer is electrically connected with the motion control card, the liquid crystal displayer and the monitoring camcorder lens. The antenna reflecting surface provided by the invention is adjustable in size and intelligently controllable in shape, is strong in adaptability, can satisfy the requirements for the shapes of reflecting surfaces under different conditions, is in a combined type and is convenient to disassemble and store.

Description

Technical field: [0001] The invention relates to an intelligent three-dimensional programmable antenna reflection surface, which belongs to the field of satellite antennas. Background technique: [0002] The antenna structure is composed of a reflective surface and a back frame structure supporting the reflective surface, where the reflective surface is the main component for the antenna to emit and receive electromagnetic signals. Depending on the needs, the size of the reflective surface varies greatly. According to the shape of the antenna, there are mainly plate antennas, whip antennas, parabolic antennas, and cylindrical antennas. Among them, the dish-type parabolic antenna reflection surface is the most common, but it is inconvenient to move and difficult to remove dust. Invention content: [0003] 1. Purpose: The purpose of the present invention is to provide an intelligent three-dimensional programmable antenna reflective surface based on a parallel mechanism. It...
