Problems solved by technology

[0004] Among them, the FAST feed support system has a large distribution span and complex structure. If the feed support system breaks down during the operation of the telescope, it will lead to the interruption of astronomical observation, and even cause structural damage and catastrophic events in severe cases.

Embodiment Construction

[0044] The technical terms involved in the present invention are explained as follows:

[0045] FAST: Five-hundred-meter Aperture Spherical Telescope, a 500-meter aperture spherical radio telescope.

[0046] FAST feed source support system: together with the active reflector system, receiver and terminal system, measurement and control system, it is called the four major process systems of the FAST project. Among them, the feed source support system mainly includes six supporting towers with an average height of more than 100 meters in the outermost circle of FAST, a feed source cabin weighing about 30 tons in the center of FAST, and six lassoes used to drive and control the movement of the feed source cabin. The driving mechanism, the docking platform of the cabin at the bottom of FAST, and the lightning protection of the overall FAST project are used to ensure the dynamic monitoring of the safe operation of the FAST feed source support system. The FAST feed support system c...

Abstract

The FAST feed support system has a large distribution span and complex structure. If the feed support system fails during the operation of the telescope, it will lead to the interruption of astronomical observation, and even cause structural damage and catastrophic events. Therefore, the present invention provides a dynamic monitoring method for the feed source support system of a FAST telescope, which can monitor the operating status of the key components of the feed source support system, and send an alarm signal in time when the abnormal working status of the structure is detected, so as to provide management decision-making and structural support. It provides a basis for timely maintenance and ensures the safe operation of the feed support system.

Description

Technical field: [0001] The invention relates to the technical field of FAST monitoring, in particular to a dynamic monitoring method of a FAST telescope feed support system. Background technique: [0002] Five-hundred-meter-Aperture-Spherical-radio-Telescope (Five-hundred-meter-Aperture-Spherical-radio-Telescope) project is referred to as FAST. The project was built in Dawodang, Jinke Village, Kedu Town, Pingtang County, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province. The natural karst land of Dawodang was used to build a spherical radio telescope with a diameter of 500 meters and an opening angle of 120 degrees. figure 1 shown. [0003] FAST consists of several major systems including site survey and excavation, active reflector, feed support, measurement and control, receiver and terminal, and observation base construction. The feed source support system is one of the three independent innovations of FAST, and its composition includes: support tower, cabl...
