Technical Field
The invention relates to the technical field of teaching systems, in particular to an intelligent teaching auxiliary system.
Background
In actual teaching of medical skills, the number of medical students is huge, while the number of teachers is limited, and a teacher usually gives skills to a plurality of medical students. Due to the limited teaching time, the medical students can only learn the operation flow and action key in the teaching time, and can be mastered only by repeatedly practicing in class. However, since the medical students have a lot of skills to master, the courses are heavy, and the medical students usually do not have enough time to exercise immediately after class, so that the medical students can exercise only after a period of time. The condition that the action is unclear or forgotten easily appears at too long time intervals, so that wrong actions appear during practice, and meanwhile, due to the fact that no teacher gives guidance beside, medical students can easily practice and strengthen wrong actions repeatedly, wrong operation habits are formed, and follow-up correction is very difficult.

And extracting the training video of the corresponding part according to the marked practical exercise training action, extracting the learning video of the corresponding part according to the marked standard practical exercise action, extracting the training video and the learning video corresponding to the operation which does not meet the standard, and sending the training video and the learning video to the training terminal.
The error operation can be conveniently determined by the medical students through the training video, the correct operation corresponding to the error operation can be conveniently checked by the medical students through the learning video, and the error operation of the medical students can be corrected, so that the medical students can be prevented from repeatedly practicing the error operation to form an error operation habit, and the correct guidance of the practical operation of the medical students can be realized.
And further, the server is also used for capturing the motion of the secondary training video to obtain the real-time training motion when receiving the secondary training video of the same practical operation project, matching the real-time training motion with the preset standard practical operation motion, matching the corresponding standard practical operation motion with the marked standard practical operation motion when the matching degree is smaller than a preset matching threshold value, and generating an early warning signal and feeding the early warning signal back to the training terminal when the matching project exists. Has the advantages that: the training video collected for the first time is used for correcting the error operation of the medical students, simultaneously carrying out basic evaluation on the abilities of the medical students, and simultaneously assisting in subsequently judging whether the error operation becomes a habit or not by recording the error operation. The secondary training video that gathers once more carries out the early warning through the mode of real-time matching, in case when the repeated erroneous operation that appears of medical student, generates early warning information and reminds, interrupts medical student's real behaviour training to avoid medical student to form the wrong operation habit, in time correct medical student's real behaviour operation.

For example, the debridement operation before the wound is sutured is correspondingly performed by skin cleaning, wound cleaning, skin cleaning, tissue cleaning, special tissue cleaning, rewashing and the like, and the corresponding operation items are also different, for example, when the wound is cleaned, the operation items for cleaning are the wound, cleaning solution and the like; the operation items for taking out foreign matters or blood clots include wounds, tweezers, and the like; the operation items for absorbing the fine dirt comprise wounds, cotton balls and the like, unmatched items exist during corresponding operation, a shielding signal is generated, and for example, the wounds do not appear during cleaning, the shielding signal is generated for reminding.
The training terminal is also used for displaying the shielding signal when receiving the shielding signal. Because the training terminal supplies medical student to use, the demonstration that shelters from the signal can remind medical student to pay attention to avoid sheltering from.
The shielding judgment module is further used for generating a shielding cancellation signal when the operation item and the secondary training video do not have an unmatched item, specifically, based on video identification, when the unmatched item is matched, namely, when the medical student does not shield any more, the shielding cancellation signal is generated, and the shielding cancellation signal is sent to the shielding timing module.
The shielding timing module is provided with preset time length, and whether the medical student continuously performs long-time shielding action or not is judged through the preset time length. The shielding timing module is used for receiving shielding signals, timing is carried out when receiving the shielding signals, timing is stopped and reset when shielding cancellation signals are received in the timing process, continuous shielding signals are generated when timing reaches preset duration, the continuous shielding signals are sent to the auxiliary reminding module, and corresponding training terminal codes are obtained to serve as object codes.
The auxiliary reminding module is used for generating auxiliary reminding information according to the object codes when receiving the continuous shielding signals, calling the real-time state table from the database, screening out the training terminal codes which are not used for acquiring the training videos at present from the real-time state table, and sending the auxiliary reminding information to the training terminals of other medical students according to the training terminal codes. Specifically, training terminal codes with the use states of other use states are screened from the real-time state table, when the number of the training terminal codes is multiple, one training terminal code which is finally screened is randomly obtained from the screened training terminal codes, and auxiliary reminding information is sent according to the training terminal codes. In the practice training of focusing attention on medical students, probably neglecting the signal of sheltering from, for avoiding medical students to practise the maloperation repeatedly, lead to medical students to form the maloperation custom, be difficult for being corrected, at this moment, generate supplementary warning information, remind it through other medical students in the same training place.
