Application programming interfaces carry out self-test to remote teaching host and the input-output unit respectively, are cut so as to provide one kind
The smooth progress of online live streaming process reliably ensure that for the testing scheme of remote teaching end equipment in fact.
Fig. 1 is the self-sensing method flow diagram at one medium-long range of embodiment of the present invention teaching end；As shown in Figure 1, it is wrapped
It includes：
S101, the type for obtaining remote teaching host and the input-output unit for remote teaching host configuration
Type；
In the present embodiment, remote teaching host is configured at remote teaching end, is connect by internet with the terminal at student end.
The type of remote teaching host can include：PC, notebook, portable terminal etc..For in the present embodiment, the remote teaching host
The type of the input-output unit of configuration includes：Audio class input-output unit, video show class input-output unit, network class
Input-output unit.Audio class input-output unit, video show class input-output unit, network class input-output unit etc. with
Remote teaching host forms remote teaching end together.
Specifically, in the present embodiment, audio class input-output unit includes：Microphone, phonographic recorder etc. and playback and recording
Related equipment, video show that class input-output unit includes the lists related with video acquisition and broadcasting such as camera, player
Member, display, network class input-output unit equipment related with internet connection including router etc..
S102, according to the type of remote teaching host and the type of input-output unit, enable corresponding application program
Interface carries out self-test to remote teaching host and the input-output unit respectively.
It,, can be by described long-range when carrying out self-test to remote teaching host in step S102 in the present embodiment
The CPU usage of host carries out self-test, so that it is determined that whether the remote teaching host is normal.

S103, judge whether the noise decibel in the voice signal that audio class input-output unit exports is less than point of setting
Shellfish threshold value, video show class input-output unit whether can carry out test pictures preview show, network inputs output unit
Whether network speed is located in the network speed threshold range of setting；
In the type that different input-output units are determined above by application programming interfaces, timing mechanism can be passed through
Mode determines the type of different input-output units.Such as the test that the input-output unit timing to remote teaching host is sent
Signal, the feedback that input-output unit is obtained within the time of setting carry out self-test.For example input a section audio stream, video
Stream, judges whether corresponding audio input output unit, video input output unit receive and can carry out normal play, sentences simultaneously
Whether the noise decibel in the voice signal of disconnected output meets the specific requirement being broadcast live online, such as by setting one decibel of threshold
Value if the noise decibel in the voice signal of output is less than the decibel threshold, judges that the self-test of audio input output unit is closed
Lattice；Otherwise it is unqualified.In the present embodiment, which is specifically as follows 70 decibels.
By showing class input-output unit load test video flowing to video, judgement is that video shows class input and output list
Whether member can be shown with the preview of test video stream, if can show, judged self-test qualification, otherwise judged that self-test is unqualified.
In addition, test media stream is sent to server by remote teaching host and receives the test media that server returns
Judge whether uplink network speed and downlink network speed meet the network speed requirement of straight line live streaming, such as specifically two network speeds of setting
Threshold value corresponds to basic, normal, high network speed grade respectively so as to form three ranges.Specifically for example, two network speed threshold values can be
100kb/s, 300kb/s are then low network speed grade less than 100kb/2, are then middle network speed etc. among 100kb/s, 300kb/s
Grade is then high network speed grade more than 300kb/s.If set one's heart network speed and downlink network speed can belong to middle network speed grade or
The high network speed grade of person then judges network inputs output unit self-test qualification；Otherwise self-test is unqualified.
When the noise decibel in the voice signal of audio class input-output unit output is less than decibel threshold, the video of setting
The preview that display class input-output unit can carry out test pictures is shown and the network speed of network inputs output unit is located at
When in the network speed threshold range of setting, the input-output unit self-test qualification at remote teaching end is stated in just judgement, meets online live streaming
