The embodiment provides a method for a dual teacher classroom microphone interaction candidate, which specifically comprises the following steps:
s1, a teacher sets an invitation number M through a teaching end and sends a continuous microphone interaction invitation, students receive the invitation through student ends, the student ends receiving the invitation are sequenced from first to last according to the receiving time, the student ends with the sequence numbers smaller than or equal to the invitation number M are marked as participants, and the student ends with the sequence numbers larger than the invitation number M are marked as pre-candidate; the student terminals of the pre-candidate are re-ranked from high to low according to the candidate Score, and the students with the re-ranked sequence number smaller than or equal to the invitation number M are marked as candidates;
the candidate Score is a total Score obtained by performing weighted average calculation on a plurality of scores under preset weights, wherein the plurality of scores comprise a historical barley connecting Score (Score 1) and a network communication Score (Score 2), and the preset weights are a historical barley connecting Score Weight (Weight 1) and a network communication Score Weight (Weight 2) respectively; the candidate Score is calculated as follows:
Score＝Score1*Weight1+Score2*Weight2。
s2, the participants and the candidates are uniformly added into the RTC room, the participants publish the audio and video streams of the own equipment and subscribe the audio and video streams published by the teachers and other participants, and the teachers subscribe the audio and video streams of the participants to perform audio and video interaction; the candidate does not release the audio and video stream, only subscribes the audio and video streams of the participants and the teacher, watches the lecture and prepares for the candidate;
s3, when the server detects that the N students are disconnected and the disconnection time exceeds a preset time threshold, marking the disconnected student ends as the disconnected students and triggering a candidate function, and reporting the current network communication score to the server by the candidate student ends; the server re-orders the candidates according to the network communication scores from high to low, marks N student terminals which are ranked first as participants, informs the student terminals to publish own audio and video streams, teachers and other participants subscribe the audio and video streams, and the candidates replace the disconnected student terminals to participate in the microphone connecting interaction.
In this embodiment, the historical barley connecting score is an average value of the completion degrees of Nr times of barley connecting interactions that the student terminal has participated in within a set time range, and the average value calculation formula is as follows:
wherein, rating 1 ，Rating 2 ，…，Rating Nr Respectively showing the 1 st, 2 nd, \8230andthe completion degree of the sub-microphone interaction.
Furthermore, the completion degree of the wheat-connecting interaction is evaluation information of the completion condition of the wheat-connecting interaction of the student, and comprises the online time Do of the student participating in the wheat-connecting interaction, the total time Dt of the wheat-connecting interaction and a preset evaluation factor c, and the completion degree Rating of the ith wheat-connecting interaction i The calculation is performed as follows:
Do i the online time Dt of the student participating in the ith wheat connecting interaction i Representing the total duration of the ith microphone connecting interaction.
In this embodiment, the network communication Score2 is obtained by converting the network communication quality detected by the student during the period of the student watching the classroom with the teacher, and calculating the network quality (quality) of the student in real time, and is calculated according to the following formula:

further, the specific process of detecting the network communication quality is as follows:
the server side sends detection message packets to the student side at a constant speed on a transmission layer based on an IP layer according to the configured ports, the detection message packets with the sending duration being less than a preset sending overtime duration value are called effective detection message packets, and the number of the effective detection message packets sent within a preset time interval is the number (Counti) of the detection message packets. After receiving the detection message packet, the student end immediately sends a response message packet to a port configured in the server end, wherein the response message packet with the response time length smaller than the preset response timeout time length value is an effective response message packet, and the number of the effective response message packets received by the server end in a preset time interval is the number of response message packets (Countj);
the calculation formula of the network quality Quantity is as follows:
it should be noted that, the server sends an effective detection message packet once, and the student responds after receiving the effective detection message packet, and if the server receives a corresponding effective response message packet, it indicates that the network communication detection result is normal this time. If the effective response message packet is not received, the network communication detection result is abnormal. Counting to obtain an effective detection message packet Counti and an effective response message packet Countj in a network quality detection time period, and calculating to obtain the difference ratio of Countj and Counti
If the smaller the value of the Percentagediff is, the higher the probability that the effective detection message packet can correspond to the effective response message packet is, the higher the probability that the network communication detection result is normal is represented. If the value of the percetadidoff is large and even exceeds the preset maximum value (the maximum value is 1) of the preset network communication quality Quantity, it can be inferred that the network communication quality of the current student end is poor, and the result of the calculation of the Counti and Countj values loses the reference value. In this case the score of the quality of network communication Quantity is 0.
It should be noted that the sending duration refers to a duration from the time when the detection message packet is sent by the server to the time when the detection message packet is received by the student, and the response duration refers to a duration from the time when the response message packet is sent by the student to the time when the response message packet is received by the server.
Various corresponding changes and modifications can be made by those skilled in the art based on the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
