Embodiment 1

[0039] Embodiment 1: There are deep and shallow movable roofs inside the roadway model, which are controlled by two sets of servo motors driven by gears through the gearbox, so that they can move up and down in the vertical direction.

[0040] The roof of the roadway model is equipped with a roof separation instrument, and its deep base point anchor and shallow base point anchor are respectively inserted into the circular cross-section grooves of the deep and shallow movable roofs.

[0041] Two scale observation mark points are set on the two scales of the roof delamination instrument, and the entire range is divided into three parts on average. Pointer observation mark points are set on the active pointer for reading, which is convenient for machine vision system observation and recognition.

[0042] The camera is fixedly erected, facing the monitored roadway section, the main optical axis of the probe is perpendicular to the plane where the measured scale is located, and is c...

Abstract

The invention provides an interactive tunnel roof separation observation experiment teaching device and a control method thereof.The experiment teaching device comprises a master control computer, a servo control mechanism, a tunnel model, a roof separation instrument and a machine vision system.The servo control mechanism is connected with the tunnel model, the roof separation instrument is connected to a roof of the tunnel model, the machine vision system and the roof separation instrument are correspondingly installed, an output of the machine vision system is connected with the master control computer, and an output of the master control computer is connected with the servo control mechanism.A student can install the roof separation instrument by himself / herself and control the movement of the roof by himself / herself, and a function of learning, reading and analyzing readings of the roof separation instrument can be achieved.The interactive tunnel roof separation observation experiment teaching device and the control method thereof are obtained by establishing a physical model in which the machine vision system capable of identifying distance change and a physical experiment device controlled by a servo motor are combined, and finally the purpose of improving an experiment teaching effect is achieved.

Description

technical field [0001] The invention relates to an experimental teaching device and a control method for observation of roadway roof separation, in particular to an interactive roadway roof separation observation experimental teaching device and a control method. Background technique [0002] Experimental teaching is one of the most basic teaching methods of engineering science and plays a vital role in teaching. According to the courses related to mining engineering, students need to have an intuitive understanding of the structure of the coal mine tunnel and its changes during mining. It is difficult for students to understand thoroughly in the lectures in the classroom, and there are many restrictions on field visits to the coal mine. Therefore, the teaching content in the laboratory is particularly important. [0003] According to the current teaching practice, the teaching content of mine pressure measurement instruments is mainly based on student visits and teacher ex...
