Active control system of 65m radio telescope primary reflecting surface

Abstract

The invention relates to an active control system of a 65m radio telescope primary reflecting surface. The active control system is characterized in that the primary reflecting surface of a radio telescope is a combined type primary reflecting surface formed by splitting a plurality of subpanels, wherein each subpanel is connected with a plurality of displacement actuators, and drivers of all the displacement actuators are respectively connected with a main control machine. The connection manner is as follows: the main surface of the 65m radio telescope is divided into eight sections in which all the displacement actuators are used as a control group; each control group is provided with a section controller; and servers of each section controller are respectively connected with the main control machine. Based on the technique of active control of a large-scale optics astronomical telescope, the invention develops the totally new structure and a control technique of a radio astronomical telescope control system. The active control system can meet more complex and precise technical requirement of the 65m radio telescope on the control system.

Description

technical field [0001] The invention relates to a control system, in particular to an active control system for the main reflection surface of a 65-meter radio telescope. This invention is a key project funded by the National Natural Science Foundation of China, "Large Aperture Active Optical Submillimeter / Millimeter Wave Telescope Scheme and Key Technology Research", and the approval number is: 10833004. Background technique [0002] Radio astronomy is a means of astronomical observation developed similar to the principle of radar, but it only receives radio waves from celestial bodies, and its main tool is radio astronomy telescopes. The main reflector of a radio astronomy telescope is a parabolic radio antenna, which is used to focus radio signals when receiving radio signals from celestial bodies. In the prior art, the main reflection surface of the radio antenna is fixedly installed on the back frame, and can perform azimuth and pitch movement when observing celestial ...
