11. An internet-based classroom remote education host control method, which is characterized in that the internet-based classroom remote education host system according to any one of claims 1-10 is based, and the control method specifically comprises the following steps:
step S101, a teacher terminal inputs a remote education request of an online classroom, and a data acquisition module acquires real-time connection data of a plurality of network links of the online classroom and sends the real-time connection data to a detection screening module;
step S102, detecting and screening network links of an online classroom by using a detection and screening module to obtain a link selection list of the online classroom, and selecting the network links of the online classroom according to the link selection list;
step S103, after the student terminal enters an online classroom, the data acquisition module acquires the voice data sent by the teacher terminal and the voice data received by the student terminal and sends the voice data to the remote analysis module;
step S104, analyzing the remote teaching condition of the network link used in the online classroom by utilizing a remote analysis module to generate an operation switching signal or an operation normal signal;
step 105, if an operation switching signal is generated, the intelligent switching module is used to intelligently switch the network links of the online class, and the network links of the online class are reselected.
12. The control method of an internet-based class remote education host according to claim 11, wherein the control method further comprises:
and S106, the data acquisition module also acquires real-time dynamic data of different student terminals and sends the data to the dynamic monitoring module, and the dynamic monitoring module is used for monitoring the class listening situation of the student terminals in the online class to generate a student abnormal signal or a student normal signal.
