Online teaching intelligent monitoring device

The invention relates to an on-line teaching intelligent monitoring device, which comprises a traversal processing mechanism, a data processing mechanism and a data processing mechanism, when the proportion of the frame number of the successive conversion pictures with the same human face imaging area in the multi-frame successive conversion pictures corresponding to the multi-frame front monitoring pictures respectively to the frame number of the multi-frame successive conversion pictures is larger than or equal to a set proportion threshold value, an overlong watching signal is sent out; and a teaching interruption mechanism which temporarily interrupts the on-line teaching of the portable terminal for a set time interval when the long-viewing signal is received. The online teaching intelligent monitoring device is intelligent in design and compact in structure. On the basis of step-by-step optimization processing of a targeted picture, an intelligent detection mechanism is adopted to carry out numerical an
