Recording and broadcasting device and method for higher vocational chemistry online teaching

Abstract

The invention discloses a recording and broadcasting device and method for higher vocational chemistry online teaching, and the device comprises a mounting plate, the left and right sides of the mounting plate are provided with limiting assemblies, the front side of the top of the mounting plate is provided with positioning holes, the exterior of the top of the mounting plate is connected with a sliding seat, and the outer wall of the front side of the sliding seat is connected with a limiting screw. The top of the sliding seat is connected with a stand column. The position of a first camera assembly in the X direction is adjusted through the sliding seat and the positioning holes formed at equal intervals under the cooperation of limiting screws, the first camera assembly is adjusted in the Z direction through the arrangement of the stand column and a height adjusting lead screw under the cooperation of an adjusting block, and through the cooperation of a sliding block and a cross beam, the position of the first camera assembly in the Y direction is adjusted through the first camera assembly, and the steering angle of the first camera assembly is adjusted through the cooperation of a connecting sleeve, a connector and an auxiliary steering assembly, so that the whole process of a chemical experiment can be clearly recorded, and the recording and broadcasting quality is ensured.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a recording and broadcasting device and method for online teaching of chemistry in higher vocational schools. Background technique [0002] With the rapid development of science and technology, there are more and more ways of information dissemination. The application of network-based teaching and the construction of courseware resources have become an important requirement for multi-functional teaching. Courseware resources can not only realize the sharing of high-quality resources inside and outside the school, but also facilitate the Students preview and review, so as to enhance students' interest in learning. [0003] In the process of making courseware, we need to use a special online teaching recording and broadcasting device. However, when the existing teaching recording and broadcasting device is recording chemistry teaching, a recording and broadcasting camera is...
