Description

Three-dimensional sand table is used in startup teaching
The technical field is as follows:
the utility model relates to a demonstration teaching equipment field especially relates to a three-dimensional sand table is used in entrepreneurship teaching.
Background
The ERP manual sand table is a novel teaching mode which is mainly based on experience, is completely different from the traditional teaching, advocates the integration of theory and practice, and fuses theoretical knowledge in the practical operation process. The method provides a mode for students to participate in the whole process through role playing, consolidate theoretical knowledge in-person experience and convert the theoretical knowledge into skills. Therefore, the teaching mode is very beneficial to strengthening the theoretical knowledge of students, training the professional skills of the students and improving the comprehensive quality of the students.
However, the traditional manual sand table is usually manufactured into a real object according to a certain template, the project is basically fixed and cannot be changed, and the manufactured sand table cannot be reused basically, so that waste is caused to a great extent. It is therefore envisaged to provide a new structure of educational sand table to address these problems.
The utility model has the following contents:
an object of the utility model is to provide a three-dimensional sand table is used in startup teaching to solve the problem that proposes in the above-mentioned background art.
The utility model provides a technical problem provide following scheme:
the utility model provides a three-dimensional sand table is used in startup teaching, includes the disk body: a magnetic powder storage layer is arranged above the tray body, and a box body for fixing is arranged below the tray body; a plurality of through holes with equal intervals are formed in the tray body, a power-on pipeline is installed in each through hole, RGB LED light-emitting units are installed on the side edges of the power-on pipelines, and transparent magnetic rods are inserted in each power-on pipeline; the electrified pipeline and the RGB LED light-emitting units are electrically connected to a control circuit board arranged in a box body below the tray body through wires.
The control circuit board is composed of a circuit consisting of a single chip microcomputer and matched elements, is externally connected to a personal computer, and can control the light emitting color and brightness of each RGB LED light emitting unit and the current intensity of each electrified pipeline through software, so that the lifting height of the magnetic rod is controlled.
The control circuit board is arranged in the control box, and an external commercial power interface and a battery module are further arranged in the control box to provide energy for the sand table integrally.
The magnetic powder is filled in the magnetic powder storage layer, the magnetic powder can be adsorbed on the outer surface of the transparent magnetic rod through magnetic force to form a smooth curved surface, and the plurality of magnetic rods are arranged at different heights to form a relatively vivid three-dimensional structure.
Compared with the prior art, the utility model has the advantages of:
the utility model has the advantages of reasonable design, can design different sand table contents according to the teacher needs, show with the three-dimensional structure of 3D simultaneously, adopt 1670 ten thousand look RGB LED light cooperation, can demonstrate any colour that wants, the user designs on computer software and accomplishes the sand table after, can audio-visually show in kind, especially is fit for demonstrating topography and geomorphology.
Description of the drawings:
FIG. 1 is a schematic view of the structure of the present invention
Fig. 2 is a schematic view of the structure of the tray body of the present invention.
Fig. 3 is a schematic view of the local structure of the magnetic rod of the present invention.
The specific implementation mode is as follows:
referring to the drawings:
the utility model provides a three-dimensional sand table is used in startup teaching, includes the disk body: a magnetic powder storage layer 2 is arranged above the tray body 1, and a box body 3 for fixing is arranged below the tray body; a plurality of through holes 4 with equal intervals are formed in the tray body 1, an electrified pipeline 5 is installed in each through hole 4, an RGB LED light-emitting unit 6 is installed on the side edge of each electrified pipeline 5, and a transparent magnetic rod 7 is inserted in each electrified pipeline 5; the electrified pipeline 5 and the RGB LED light-emitting unit 6 are electrically connected to a control circuit board arranged in the box body 3 below the disc body 1 through wires 8. The control circuit board is composed of a circuit consisting of a single chip microcomputer and matched elements, is externally connected to a personal computer, and can control the light emitting color and brightness of each RGB LED light emitting unit and the current intensity of each electrified pipeline through software, so that the lifting height of the magnetic rod is controlled. The control circuit board is arranged in the control box, and an external commercial power interface and a battery module are further arranged in the control box to provide energy for the sand table integrally. The magnetic powder is filled in the magnetic powder storage layer, the magnetic powder can be adsorbed on the outer surface of the transparent magnetic rod through magnetic force to form a smooth curved surface, and the plurality of magnetic rods are arranged at different heights to form a relatively vivid three-dimensional structure.
The embodiments of the present invention are only descriptions of the preferred embodiments of the present invention, not right the present invention is designed and limited, without departing from the design concept of the present invention, the technical personnel in the field should fall into the protection scope of the present invention for various modifications and improvements made by the technical solution of the present invention, and the technical contents of the present invention are all recorded in the claims.
