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

Embodiment 1

[0042] Example 1: like Figure 7 Shown workflow of the present invention:

[0043] 1) Power-on start: firstly carry out the self-test program, which mainly checks whether each hardware device of the device can work normally, whether the hardware dog system can work normally, and whether the wireless WIFI network can be accessed normally. If it is normal, go to the next step, otherwise it will stop automatically and wait for maintenance;

[0044] 2) After passing the self-test, start the "software dog program" and "power monitoring and management program". The software dog program is a long-running background program, which is mainly responsible for receiving regular polling information from the upper computer to ensure the normal transmission of the wireless WIFI network; the "power monitoring and management program" is mainly responsible for monitoring the current power supply. If abnormal, the battery inside the device will be automatically activated for power supply. I...

Embodiment 2

[0049] Example 2: The present invention realizes classroom Teaching inspection sign-in The method of operation: the terminal is installed on each desk in the classroom. When students are in class, they enter their student ID on the terminal. At this time, the terminal uploads the student ID to the upper control computer, and the upper control computer determines whether the student is Should be taught in that class. If not, the student will be prompted to go to the wrong classroom. If so, the terminal equipment will be notified to take pictures. There will be prompts during the photographing process. Students need to take a frontal photo under the prompt as a class attendance file, which will be encrypted by the terminal and uploaded to the upper control computer. In order to prevent students from skipping classes and replacing sign-in in the classroom. The terminal will randomly take snapshots during the class, and there is no prompt during the capture process. The devic...

Embodiment 3

[0050] Example 3: The present invention is realizing Practical aspects of classroom teaching The method of operation: During the class, the teacher can control the computer through the host, and through the remote control command, designate the terminal of the classroom to display a single-choice question. Students enter their own choice answers through the terminal buttons. The terminal will automatically upload the results of the students' operations to the upper control computer through the wireless WIFI network, and the upper control computer will automatically perform option statistics and display the current student answer chart in real time. At the same time, the terminal will automatically turn on the audio and video collection equipment, and record and record the whole process of answering. Video and audio information pass through the processing card in the terminal, and after real-time preprocessing, they are mixed and encoded into one signal, and then encrypted ...

Abstract

The invention discloses an intelligent network terminal for collecting and encrypting classroom teaching multimedia information in real time and a working method of the intelligent network terminal for collecting and encrypting the classroom teaching multimedia information in real time. The intelligent network terminal comprises a hardware module and a software module, the hardware module of the intelligent network terminal is installed on a single desk, teacher and student mutual information such as image-texts, videos and audios in the classroom teaching process is collected, the collected information is optimized and encrypted through a self-control expansion card, and the information is transmitted to an upper control computer through the WIFI; according to the intelligent network terminal, a command of the upper control computer is received through the WIFI, and image-text, picture, video and audio communication between groups of the terminal is achieved in a classroom; by means of the intelligent network terminal, the classroom teaching quality is improved, real-time data collecting is provided for classroom teaching surveying, basic data are provided for teaching evaluation, the whole device faces classroom teaching, the multiple protective technology is adopted, it is guaranteed that the intelligent network terminal stably operates all the day for a long time, classroom teaching data are accurately collected in real time, and safety transmission and storage are achieved.

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 ...
