Problems solved by technology

[0002] At present, the experimental teaching of biochemistry majors is only suitable for teachers to conduct experimental teaching process based on observation for a small number of students, and the student experiment and teacher experiment cannot be synchronized, and the teacher only monitors or evaluates part of the process and results of the student experiment. Every detail of the experimental teaching process cannot be exhausted
The number of people participating in the experimental learning of specific majors in different universities is small, the progress is inconsistent, and the experimental teaching cannot realize real-time sharing of resources
[0003] The existing teaching videos about microbes are textbook-level, and the recording process is recorded in detail by professional videographers for the whole process and key steps of the experimental process. Watching these teaching videos can systematically understand the experimental process and results, but usually still requires a microbiology teacher Conduct on-site repeated experiments in the microbiology laboratory to verify and demonstrate teaching cognition to students, but ordinary microbiology experiment teachers do not have professional camera and recording conditions, so remote experimental teaching cannot be realized. The common situation is that students observe the experimental process around the teacher , or it is only completed by the teacher's experiment, which does not have the interaction and interaction of experimental teaching, resulting in poor cognitive effect of students
[0004] The space of the biochemistry teaching laboratory is limited, and the range of students watching is small, which is not conducive to the effective learning of all students
The specific manifestations are: 1. It is not conducive to the interaction between remote teachers and students. Students only observe teaching and are prone to fatigue
2. Teachers cannot see remote students during biology teaching or experiments
3. Unable to cope with answering questions from multiple askers at the same time
4. Students can only observe the experiment process from one camera angle, and multiple pairs of eyes observe the same angle
5. The existing teaching video has been cut and the long-lasting process has been deleted, causing students to have no exact concept of the experiment time

Embodiment 1

[0036] Embodiment 1: A remote display interactive system for biochemical experiment teaching, including a display device used as an experimental teaching application and a plurality of demonstration devices used as experimental learning, such as figure 1 The shown display device and multiple demonstration devices respectively establish communication with the server through wifi. The display device and demonstration device provided by the present invention are a kind of such as figure 2 The interactive demonstration device shown can be combined with the experimental bench for temporary construction.

[0037] Specifically, from figure 2 It can be seen that both the display device and the demonstration device include a curved beam, a display part and an image acquisition part. The curved beam can be supported and moved independently, which includes a straight section in the middle of the upper side and arc sections on both sides. The curved beam can be adjusted up and down, u...

Embodiment 2

[0044] Embodiment 2: Based on the fact that the angle of the camera is moved artificially in Embodiment 1, during the experiment, the camera at a fixed position is likely to be unable to display the best imaging effect due to the obstruction of instruments, utensils, etc., so this embodiment An automatic control mechanism is used to control the movement of the front and side cameras. Such as image 3 As shown, the linear track is fixed with a protruding T-shaped rack on the front side of the straight section on the upper side of the curved beam. The teeth are distributed on its front side, and the walking motor (stepping motor) is fixed on the slider. The gear installed on the rotating shaft of the traveling motor meshes with the rack. In this way, the camera can be moved to an appropriate position in a controlled manner. The camera also needs to be able to automatically adjust the corresponding angle to ensure that it can always be aligned with the experimental area or even ...

Embodiment 3

[0046] Embodiment 3: on the basis of embodiment 2, as figure 2 As shown, the main bracket 1 and the auxiliary bracket 2 are set together by the columns on both sides. Both can be upgraded and adjusted and can be locked. The lower end of the auxiliary bracket 2 is fixed on the base 3, and the base 3 is equipped with walking wheels to move. The top of the main support 1 is fixed with a curved beam 4, which includes a straight line section 41 and arc sections 42 at both ends, and a T-shaped slide rail 10 is arranged on the front side of the straight line section, and a slide block 91 is arranged on its external matching sleeve, such as Figure 5 As shown, the rear side of the slide block 91 contains a T-shaped chute, which can be matched and sleeved on the T-shaped slide rail 10 and can slide. A stepper motor 92 is installed on the upper side of the slide block 91 (a gear is installed on the motor output shaft, and at the same time A rack is provided on the side of the slide rai...

Abstract

The invention discloses a remote display interaction system for biochemical experiment teaching. The remote display interaction system comprises a display device, at least one demonstration device and a server, wherein both the presentation device and the presentation device include the following content to desire to enable a synchronous presentation and presentation process. Each of the display device and the demonstration device comprises a curved beam capable of being independently supported, wherein the curved beam comprises a straight line section in the middle of the upper side and arc sections on the two sides, and the curved beam can be adjusted to ascend and descend, unfolded leftwards and rightwards and locked. According to the system capable of enabling student experiments and teacher experiments to be performed synchronously, different devices can observe each progress of the experiment process from multiple angles, synchronous experiment and mutual communication functions of teachers and students can be realized, experiment learning requirements may come from multiple different college laboratories, the experiment devices are scattered, and students are dispersed.
