Embodiment 1

[0028] A holographic projection teaching device based on 5G network transmission and control, such as figure 1 As shown: it includes a projection cabinet 1, a polygonal pyramid combination screen 2 located in the projection cabinet 1, and a plurality of projectors for projecting teaching images to the polygonal pyramid combination screen 2. The transparent panel is hinged on the projection cabinet body 1 by rotation, and the transparent panel is hinged on the projection cabinet body 1 through the self-locking hinge 3. In this embodiment, the transparent panel forms a square platform, and the angle between the transparent panel and the horizontal direction The angle range is 15°-75°, which allows the transparent plate to form an upright quadrangular prism or an inverted quadrangular prism, that is, the small end of the regular quadrangular prism faces upward and the large end faces downward, and the inverted quadrangular prism has the small end facing The lower end faces upward...

Embodiment 2

[0035] The difference with Embodiment 1 is that, if Figure 4As shown, there is a gap between the transparent panel and the inner bottom of the polygonal pyramid combination screen 2 because of the hinge 3, and the projector is installed on the side of the light shielding plate 7 facing the polygonal pyramid combination screen 2, and a cavity is provided in the light shielding plate 7, and the projector The heat dissipation port is located in the cavity, and the fan 8 for cooling the cavity is installed on the right side wall of the shading plate 7, and an air guide tube 9 is connected between the shading plate 7 and the inner bottom of the projection cabinet body 1, and the air guide tube 9 communicates with the cavity and multiple In the inner space of the pyramid composite screen 2, the air guide tube 9 is connected to the inner bottom of the pyramid composite screen 2, and the air guide tube 9 guides the air in the cavity from the bottom of the polygon pyramid composite scr...

Abstract

The invention relates to the technical field of intelligent teaching, and specifically relates to a holographic projection teaching apparatus for transmission and control based on a 5G network. The holographic projection teaching apparatus comprises a projection cabinet body, a polygonal pyramid combination screen located in the projection cabinet, and a plurality of projectors for projecting teaching images to the polygonal pyramid combination screen, the projectors are distributed in symmetry centering on the vertical center of gravity line of the projection cabinet body, the polygonal pyramid combination screen comprises a plurality of projection plates, the apparatus also comprises a control system and a user terminal, and the control system wirelessly receives the teaching images froma teaching system through a 5G protocol, wirelessly receives a control instruction of the user terminal through the 5G protocol, and controls the projectors to project the teaching images according to the control instruction. According to the apparatus, the projection plates are adjusted until phantasms are clear when formed stereoscopic phantasms are blurry, and image blurry caused by position deviation of the polygonal pyramid combination screen or the projectors is avoided.

Description

technical field [0001] The invention relates to the field of intelligent teaching devices, in particular to a holographic projection teaching device for transmission and control based on a 5G network. Background technique [0002] Students acquire professional skills through the study of different disciplines. Some disciplines require students to have good three-dimensional space ability, such as automotive electronics, electromechanical and mechanical. At present, the teaching of various disciplines generally uses multimedia equipment composed of computers, projectors, and projection screens for teaching. The projector projects the pre-stored 3D structure or 3D parts onto the projection screen to display teaching, and these 3D images are displayed in two dimensions. However, students still cannot observe the specific structural features of the three-dimensional model in detail from this two-dimensional plane display teaching. [0003] The characteristics of holographic pro...
