Image acquisition system and centrifuge model testing system

Abstract

The invention provides an image acquisition system and a centrifuge model testing system, relating to the technical field of image acquisition. The centrifuge model testing system includes a centrifuge, a model box provided in the basket of the centrifuge, and a test model disposed inside the model box. The image acquisition system includes a high speed industrial camera, a first photoelectric converter, an optical fiber slip ring, a second photoelectric converter, and a computer. The high speed industrial camera converts the acquired state information of the test model under high centrifugal acceleration condition into a first electrical signal, the first photoelectric converter converts the received first electrical signal into an optical signal and transmits the optical signal to the second photoelectric converter through the optical fiber slip ring, and the second photoelectric converter converts the received optical signal into a second electrical signal, and the computer stores and analyses the received second electrical signal. According to the invention, the problem that a conventional image acquisition system cannot completely and reliably acquire the test state information of the centrifugal test model can be solved.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an image acquisition system and a centrifuge model test system. Background technique [0002] In the field of engineering, a small-scale test model is often used to reproduce an event to study the phenomena that may exist and occur in the prototype, or to use model tests to predict engineering practice to reveal and analyze the nature and mechanism of phenomena. Among them, in the fields of geotechnical engineering and geological engineering, the main load that causes the deformation of rock and soil is the self-weight stress of the soil. When carrying out model tests, because the self-weight stress of the small-scale test model is much lower than that of its prototype, there is a problem that it cannot truly reflect the deformation process of the prototype. [0003] Based on the above problems, in the existing technology, a centrifuge is generally used to provide a hi...
