Intelligent network terminal and working method for real-time collection and encryption of multimedia information

Abstract

The invention discloses an intelligent network terminal for real-time collection and encryption of classroom teaching multimedia information and a working method thereof. The intelligent network terminal includes a hardware module and a software module, and the hardware module of the terminal is installed on a single desk. In the process of classroom teaching, teachers-student interaction information such as graphics, video, and audio is collected, and the collected information is optimized and encrypted using a self-made expansion card, and transmitted to the upper control computer through the wireless WIFI network; the terminal receives data through the wireless WIFI network The command of the host control computer realizes text, picture, video and audio communication between terminal groups in the classroom; this equipment is based on the improvement of classroom teaching quality, provides real-time data collection for classroom teaching research, and provides basic data for teaching evaluation. The equipment is oriented to classroom teaching, and adopts multiple protection technologies to ensure that the equipment runs stably for a long time around the clock, real-time and accurate collection of classroom teaching data, and safe transmission and storage.

Description

technical field [0001] The invention relates to the field of modern classroom teaching equipment, in particular to an intelligent network terminal for real-time collection and encryption of classroom teaching multimedia information and a working method thereof. Background technique [0002] Education informatization has been developed for many years, mainly in the construction of course resources and course interaction platforms. But most of these works have achieved teaching outside the classroom, such as teachers and students can communicate outside the classroom. Educational informatization does not really focus on "in the classroom", and the main focus of educational informatization is not on the "classroom", the most important place for teaching. This is the blind spot of current education informatization. The diversity of classroom teaching and the richness of information in the classroom teaching process lead to the inability to record the classroom in an all-round ...

AI Technical Summary

Problems solved by technology

The diversity of classroom teaching and the richness of information in the classroom teaching process lead to the inability to record the classroom in an all-round way under the traditional technical conditions, and only stay in the aspect of equipped with teachers' computers and projectors, which leads to education Informatization cannot be deepened in the classroom

[0003] Although ordinary mobile phones or tablet computers can realize wireless network communication and audio and video recording functions, they cannot undertake the collection and interaction of classroom teaching information

The main reasons are: 1) It cannot achieve information security. Classroom teaching information contains a lot of private information. If there are no necessary security encryption measures, this information is easy to leak and cause harm to individuals or teams; 2) Integrity of teaching information. Smartphones and tablets are not designed for complete and real-time data collection. They cannot guarantee the integrity of information in audio and video data collection, especially the synchronization of audio and video information; 3) Long-term reliability cannot be achieved collection

Smartphones or tablets are mainly aimed at individual users, and do not consider the special environment of multi-person use and classrooms, and often cannot guarantee long-term stable and reliable operation

[0004] Patent 200920138269.0 discloses an improved teaching informatization management system. The device realizes the improvement of teaching informatization through the service center management platform, mobile SMS center, school news receiver, attendance card reader, mobile phone and front-end WEB browsing and management equipment. It is an energy-saving and environmentally-friendly system that manages the communication quality of the system, reduces the failure rate of card readers; but this system is mainly a communication platform for schools, families and school communication, and can only improve the information communication of students in the teaching process. The smooth, unable to improve the school's teaching quality and teaching level

[0005] Patent 201120409495.5 discloses a wireless teaching feedback system. The system transmits wireless signals to the wireless receiving unit through the main receiver and several student controllers to form a wireless teaching feedback system, which avoids the need for wiring in the wired teaching feedback system. The complexity of teaching information feedback and effect analysis and evaluation can be carried out in real time, but the system only inputs teaching information through keyboards and buttons, and the data transmitted through wireless networks is also relatively simple, which cannot form a systematic collection of teaching information and Collection system, the overall device is relatively simple
