s101, acquiring the type of a remote teaching host and the type of an input/output unit configured for the remote teaching host;
in this embodiment, the remote teaching host is configured at the remote teaching end and is connected with the terminal of the student end through the internet. The types of remote teaching hosts may include: PC, notebook, portable terminal, etc. In this embodiment, the types of the input/output unit configured by the remote teaching host include: the system comprises an audio input/output unit, a video display input/output unit and a network input/output unit. The audio input and output unit, the video display input and output unit, the network input and output unit and the like form a remote teaching end together with the remote teaching host.

And S102, starting corresponding application program interfaces according to the type of the remote teaching host and the type of the input/output unit, and respectively carrying out self-detection on the remote teaching host and the input/output unit.
In this embodiment, in step S102, when performing self-detection on the remote teaching host, whether the remote teaching host is normal or not may be determined by performing self-detection on the CPU occupancy of the remote teaching host.
In this embodiment, in step S102, during the self-detection, the available application program interfaces of the audio input/output unit, the video input/output unit, the display input/output unit, and the network input/output unit may be determined first, and then the processor of the remote teaching host, the audio input/output unit, the video display input/output unit, and the network input/output unit may be selected in sequence or self-detected one by one.

S103, judging whether noise decibels in the sound signals output by the audio input and output unit are smaller than a set decibel threshold value or not, whether the video display input and output unit can perform preview display of a test picture or not, and whether the network speed of the network input and output unit is within a set network speed threshold range or not;
when the types of the different input and output units are determined through the application program interface, the types of the different input and output units can be determined through a timing mechanism. For example, a test signal is sent to the input/output unit of the remote teaching host at regular time, and the feedback of the input/output unit is obtained within a set time for self-detection. For example, inputting a section of audio stream and video stream, judging whether the corresponding audio input/output unit and video input/output unit receive and can normally play, and simultaneously judging whether the noise decibel in the output sound signal meets the specific requirement of online live broadcast, for example, by setting a decibel threshold, if the noise decibel in the output sound signal is less than the decibel threshold, judging that the audio input/output unit is qualified by self-check; otherwise, the product is not qualified. In this embodiment, the decibel threshold may be 70 decibels.
And loading the test video stream to the video display input and output unit, and judging whether the video display input and output unit can test the preview display of the video stream, wherein if the video display input and output unit can display the preview display, the self-inspection is judged to be qualified, and otherwise, the self-inspection is judged to be unqualified.
In addition, whether the uplink network speed and the downlink network speed meet the network speed requirement of the straight line live broadcast or not is judged by sending a test media stream to the server and receiving a test media returned by the server through the remote teaching host, for example, two network speed thresholds are specifically set so as to form three ranges which respectively correspond to low, medium and high network speed grades.
