And step 110, receiving the classroom teaching video-audio data and the classroom listening video-audio data sent by the recording and broadcasting system of the current teaching site.
Specifically, the current teaching place may be a classroom a of a school, and the school may be any one of schools such as a primary school, a middle school, a university, and a professional school.
Each classroom is provided with a recorded broadcast system which tracks, records and broadcasts the targets in the course of teaching. For example, classroom a is provided with five cameras, be used for shooting teacher's of giving lessons, the blackboard, the student, front panorama and back panorama respectively, every camera has corresponding microphone, teacher's of giving lessons is when saying and giving, switch to the audio data of lecturing that first camera and corresponding microphone were recorded, when interactive, if teacher is asking, then switch to teacher's of first camera shooting asking the picture, teacher is when writing, switch to the picture of the blackboard of second camera shooting, teacher is when patrolling, switch to the picture of the podium panorama of third camera shooting. As to how to realize the switching, Artificial Intelligence (AI), intelligent identification technology and big data technology can be adopted for identification, so as to perform switching according to the identification result, thereby performing targeted recording and seamless switching in the recording process, and then performing timestamp alignment synthesis on the audio data recorded by the microphone.
In the switching process, prompt information can be added for each section of video and audio, for example, keywords such as teaching video and audio data, interactive video and audio data, answering and remitting video and audio data and the like can be added in the teaching video and audio data for prompting.
When recording teacher's teaching, can carry out the feature to the student and record and the panorama is recorded, recording this moment can switch between student's feature and student's panorama, and the switching is with the student's action of discernment as trigger condition for example, the student answers the question at holding, can record the student's of holding the hand image, the student is listening to saying, can record the panoramic video of listening to saying. And then, carrying out time stamp alignment synthesis on the audio data recorded by the microphone, thereby obtaining class listening audio and video data of the student, and subsequently, the class listening audio and video data can be used as a basis for researching the class listening fidelity of the student.
The control system and the recording and broadcasting system can communicate through the WIFI module.
And step 111, sending the classroom teaching video and audio data to at least one classroom terminal according to a preset list so that the classroom terminal plays the classroom teaching video and audio data, and sending the classroom listening video and audio data to at least one supervision terminal so that the supervision terminal plays the classroom listening video and audio data.
The preset list includes an Identity (ID) of the class terminal and an ID of the supervisory terminal.
The classroom terminal can be a terminal of other classrooms, for example, the classroom teaching video and audio data in classroom a can be sent to classroom terminals of three classrooms b, c and d, so that the classroom teaching video and audio data in classroom b, c and d can be displayed in real time or non-real time. The classroom terminal can also be a remote classroom terminal, thereby realizing remote teaching. The classroom terminal can also be a live broadcast terminal, so that live broadcast teaching can be carried out.
The supervision terminal can be a terminal of a school educational administration department, so that the educational administration department acquires the behavior of students, and the students can be managed conveniently. The supervision terminal can also be a home terminal, so that the family can conveniently and quickly acquire the classroom performance of students. The supervision terminal can also be an intelligent class board outside a classroom, so that patrol personnel can conveniently acquire class-listening video and audio data of students in a classroom without entering the classroom in the class patrol process.
The IDs of the supervision terminals and the IDs of the class terminals may be stored in a preset list, and after selection in the preset list, the class terminal to which the class teaching video/audio data is to be sent and the supervision terminal to which the class listening video/audio data is to be sent are determined.
The list can be deleted and added, so that classroom terminals and supervision terminals can be added or reduced as required.
Further, step 111 is followed by:
receiving a first analysis result and a second analysis result; the first analysis result is obtained after the classroom teaching video-audio data are analyzed, and the second analysis result is obtained after the classroom teaching video-audio data are analyzed;
and sending the first analysis result and the second analysis result to one or more of at least one class terminal, at least one supervision terminal and a smart class card.
The classroom teaching video and audio data comprises various teaching behaviors, such as lectures, writing on a blackboard, demonstration, questioning, inspection tour and teacher-student interaction.
The first analysis result is that the teaching time length, the writing time length, the demonstration time length, the question time length and the teacher-student interaction time length respectively account for the proportion of the class teaching video-audio data.
The time length of each type of video and audio can be counted according to the time stamp of each type of video and audio in the video and audio data for teaching, so that the proportion of the time length of each type of video and audio to the time length of the video and audio data for teaching in a classroom is calculated.
And the second analysis result is the proportion of the number of the listening people, the number of the holding people, the number of the discussion people and the number of the classroom attention concentration people in each frame of image of the classroom listening video-audio data to the total number of the people.
Specifically, according to the panoramic images of students, the number of people on duty is obtained in real time, and then the total number of people of classes recorded in the intelligent class cards is called, so that the class rate can be obtained. The number of listening and speaking and the number of attention-focusing persons in a classroom can be counted in real time according to the video and audio data of each frame, the number of listening and speaking at the position can be judged according to the emotion, for example, the emotion is normal, the listening and speaking can be regarded as serious, the number of attention-focusing persons can also be judged according to the emotion, for example, the emotion is normal, and the body action is hand lifting.
The control system is provided with a control panel, and a first instruction for indicating the start of screen projection display can be input through the control panel, so that screen projection display can be performed after the screen projection instruction is received.
And 113, performing screen projection display on the video and audio data for classroom teaching according to the first instruction.
In one example, the classrooms a, b, c and d may share one control system, and the first instruction may further include a classroom ID, so that after receiving the first instruction, the classroom teaching video and audio data is displayed in a screen projection manner according to the classroom ID corresponding to the first instruction, thereby facilitating the screen projection viewing of classroom teaching of students in different classrooms. Meanwhile, a plurality of classrooms share one control system, so that the simultaneous management of the plurality of classrooms by the control system is realized. The classroom ID can be associated with the screen projection terminal ID of the classroom, which can also be expressed in terms of screen projection terminal ID.
Further, step 113 is followed by: receiving a third instruction for indicating to close the screen projection display; and closing screen projection display of the video and audio data of the teaching behavior according to the third instruction.
And when the control system receives the third instruction, the screen projection display can be closed according to the third instruction. Meanwhile, the third instruction may further include a classroom ID, and the screen projection display of the classroom corresponding to the classroom ID may be closed according to the classroom ID in the third instruction.
When giving lessons, teachers can issue objective questions, the objective questions can be issued to answer sheet receivers of students, and after the answer sheet receivers of the students receive the objective questions, the answer sheet receivers send answer data to the control system after the students answer the questions. The control system may receive the plurality of answer data and may selectively display, for example, the answer data of at least one student of the plurality of student IDs.
In one example, after a selection, such as a touch operation, is made on the control system, so as to generate a touch operation instruction, a second instruction for selecting and displaying student answer data is generated, such as selecting student a answer data.
And step 116, displaying the answer data of the ID of the target student on a screen according to the ID of the target student.
Continuing to connect the previous example, after receiving a second instruction for selecting the answer data of the student A, the control system can control the screen projection terminal to display the answer data of the student A in a screen projection manner, so that a teacher can explain the questions by taking the student A as an example.
The IP broadcasting changes the signals transmitted by the traditional broadcasting into digital signals, so that the digital signals can be transmitted to any required place through the Internet or a local area network, and the distance limit is broken through.
After receiving the IP broadcast message, the control system analyzes the IP broadcast message to obtain the content, the type and the target of the IP broadcast message. By way of example and not limitation, the target may be a whole student, three-grade two or five-grade three, etc.
And step 119, when the type of the IP broadcast message is the emergency type, immediately playing the content of the IP broadcast message.
The emergency type comprises emergency broadcast, and when the emergency type exists, the control system can control the related module to play immediately.
And step 120, when the type of the IP broadcast message is a non-emergency type, searching the information of the class schedule, and determining whether the current teaching field is the classroom ID corresponding to the object.
The non-emergency type comprises indoor broadcasting, and when the IP broadcasting message is indoor broadcasting, the content of the IP broadcasting message comprises broadcasting time; according to the targeted object and the playing time, searching the classroom table information, and determining the classroom ID corresponding to the targeted object at the playing time; and judging whether the classroom ID is the current teaching place.
When the classroom ID is the current teaching field, the class attendance time and the class leaving time are determined according to the class schedule information; determining target playing time according to the playing time, the class time and the class leaving time; and sending the content of the IP broadcast message to the ID of the voice playing system of the current teaching place at the target playing time.
Therefore, when the type is a non-emergency type, the classroom ID corresponding to the object during playing can be determined according to the object and the playing time, and one playing time is determined according to the class-in time and the class-out time corresponding to the classroom ID so as to avoid influencing the class-in process of students, thereby realizing the timing broadcast of the classroom corresponding to the object.
And 121, when the current teaching field is the classroom ID corresponding to the object, sending the content of the IP broadcast message to the voice playing system ID of the current teaching field so that the voice playing system plays the content of the IP broadcast message.
When the time is the target playing time, the control system sends the content of the IP broadcast message to the voice playing system ID, and the voice playing system can be a loudspeaker and other modules, so that the non-emergency IP broadcast can be played at regular time, and the normal class is not influenced by the playing. Thereby improving the user experience.
Further, this application still includes: and storing the classroom teaching video-audio data, the classroom listening video-audio data, the answer data and the IP broadcast message. Therefore, the data are stored in the control system, so that the data can be directly called from the control system, and the user experience is improved.
