Automatic test system for model test displacement data and test method thereof

Abstract

The invention discloses an automatic test system for model test displacement data and a test method thereof. The automatic test system comprises a displacement transfer unit, a displacement measurement unit, a signal conversion unit, a data processing unit and a visualized human computer interaction interface system, wherein the displacement transfer unit is connected with a model; when the model body displaces, the displacement measurement unit outputs pulse signals of which the pulse number is in proportion to displacement amount; after the output pulse signals are received, processed and converted into an identifiable positive logic signal by the signal conversion unit, the identifiable positive logic signal is transmitted to the signal processing unit; the signal processing unit calculates the number of the pulse to calculate model displacement; and the model displacement is finally stored and displayed on the visualized human computer interaction interface system to automatically generate a model displacement time interval curve for testers to dynamically observe and monitor model displacement in real time. According to the automatic test system for model test displacement data and the test method thereof, the digitization, the visualization and the intellectualization of the automatic measurement of the model displacement in the underground engineering model test in the fields of hydropower, traffic, energy, resource and defence construction fields can be realized.

Description

technical field [0001] The invention relates to an automatic test system for model test displacement data and a test method thereof, which can realize digitization, visualization and intelligence of model displacement measurement in underground engineering model tests in the fields of hydropower, transportation, energy, resources and national defense engineering. Background technique [0002] In the underground engineering in the fields of hydropower, transportation, energy, resources and national defense engineering, with the increase of burial depth, the structure, mechanical properties and engineering response of the surrounding rock in the deep cavern are divided under the condition of high ground stress. For a series of new characteristic scientific phenomena such as rupture, large deformation, and impact damage, theoretical research should be used on the one hand, and model experiments should be used more for research on these characteristic scientific phenomena. To co...
