Embodiment 1

[0024] figure 1 It is a structural block diagram of a classroom recording device provided by an embodiment of the present invention, which is detailed as follows:

[0025] Heart rate sensor 1 for detecting heart rate during class;

[0026] The control module 2 connected to the heart rate sensor 1 is used to receive the detected heart rate. When the detected heart rate is lower than the set heart rate threshold, control the microphone to turn on to identify whether there is clear sound in the classroom environment, and when there is clear sound When, generate a recording file;

[0027] The storage module 3 connected to the microphone is used to store the generated recording file.

[0028] Further, the control module 2 is also used to configure the corresponding relationship between age and heart rate threshold.

[0029] Set the heart rate threshold according to the corresponding relationship between the configured age and the heart rate threshold, combined with the entered age.

Embodiment 2

[0044] figure 2 It is a structural block diagram provided by an embodiment of the present invention, which is detailed as follows:

[0045] Heart rate sensor 1 detects the heart rate during class;

[0046] The control module 2 receives the heart rate detected by the heart rate sensor 1, and when the detected heart rate is lower than the set heart rate threshold, it controls the microphone to turn on and recognizes whether there is clear sound in the classroom environment, and when there is clear sound, it generates a recording file ;

[0047] The storage module 3 stores the generated recording file.

[0048] In the embodiment of the present invention, according to the change state of the student's heart rate during class, the time period when the student's mental state is not good is automatically recognized, and the teacher's lecture content during this time period is automatically recorded, and the lecture content is generated into a recording file to provide Students consolidate ...

Embodiment 3

[0050] image 3 It is the first implementation flow chart of generating a recording file provided by the embodiment of the present invention, and the details are as follows:

[0051] S301: When there is a clear sound, it is judged whether the heart rate reminder exceeds the heart rate threshold for a certain period of time, and the heart rate reminder refers to a reminder that the detected heart rate is lower than the set heart rate threshold;

[0052] S302: When the duration of the heart rate reminder exceeds the set time, the recording automatically ends to generate a recording file.

[0053] In the embodiment of the present invention, a recording file is generated to facilitate students to consolidate their learning after class.

Abstract

The invention, which is suitable for the classroom teaching field, provides a classroom recording device and recording method. The classroom recording device comprises a heart rate sensor, a control module, and a storage module. To be specific, the heart rate sensor is used for detecting a heart rate in class. The control module connected with the heart rate sensor is used for receiving the detected heart rate, controlling turning on of a microphone when the detected heart rate is lower than a set heart rate threshold value, identifying whether clear sound exists in the classroom environment, and if so, generating a recording file. The storage module connected with the microphone is used for storing the generated recording file. With the method, a problem of lack of equipment capable of recording a lesson content of a teacher automatically during the period when students can not focus attention on the lesson in the prior art can be solved. Therefore, the trouble of playing all recording content at one time and searching the record can be saved, thereby saving time and improving the playing efficiency of the recording file.

Description

Technical field [0001] The invention belongs to the field of classroom teaching, and particularly relates to a classroom recording device and a recording method. Background technique [0002] During the class, students will inevitably have periods of bad mental state, so it is easy to miss the knowledge points during the class, or to grasp some knowledge points. [0003] The current method only re-watches the classroom video or listens to the classroom recording to supplement the learning. This method has two drawbacks: [0004] First, it is a waste of time to hear everything hard; [0005] Second, students cannot find out which part is not fully mastered. [0006] Therefore, in the prior art, there is a lack of equipment for automatically recording the content of the teacher's lecture during the time period when the student's mental state is not good. Summary of the invention [0007] The purpose of the embodiments of the present invention is to provide a classroom recording device, w...
