Background
With the continuous development of scientific technology, deep learning, education big data and the like become the hotspots of education research, and it is very important to deeply analyze the learning behaviors of students in the big data background, however, students are still easy to be tired in the learning process, fatigue is a physiological phenomenon caused by excessive labor of physical or mental, the fatigue of students can be caused by various factors, and how to effectively monitor the fatigue state of students in the learning process under the big data background further corrects the learning behaviors of students, so that the students can reach a better learning state, which becomes a big problem.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a learning state monitoring system based on big data.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a learning state monitoring system based on big data comprises a glasses body, a behavior database module, a comparison analysis and judgment module, an inquiry module and a monitoring device detachably mounted on the glasses body, wherein the monitoring device comprises an infrared detector used for collecting eye images of students, an image processing module, a vibration device and a wireless transmission module; the wireless transmission module wirelessly transmits the eye images and the abnormal duration of the learning state to the behavior database module, the comparison analysis and judgment module counts the number of students with abnormal learning states at each time period, and the query module is used for querying data in the behavior database module.
In another preferred embodiment, the comparison analysis and judgment module comprises an individual learning state database and a group learning state database, wherein the individual learning state is used for judging whether the individual is in a fatigue state, and the group learning state database is used for counting the abnormal number of students in the learning state in each period.
In another preferred embodiment, the threshold is 2 s.
In another preferred embodiment, the monitoring devices are two, and the two monitoring devices are symmetrically distributed on the upper parts of the two glasses frames of the glasses body.
In another preferred embodiment, the image processing module analyzes the eye image, and determines that the learning state is abnormal when the pupil size deviates from a preset normal pupil size range.
The invention has the beneficial effects that:
the eye condition of the student is monitored through the infrared detector, the eye closing condition, the eye blinking condition and the pupil area condition of the student are monitored mainly through monitoring, whether the student is in a fatigue learning state or not is judged through algorithm analysis at last, a teacher can timely find the student in the learning state abnormity to give help to the student, when the student is in group fatigue, the teacher can think back that the student is not enough in the teaching process and adjusts the student, the method for monitoring the fatigue state through eye movement has the advantages of higher monitoring efficiency and lower cost.
The invention is further explained in detail with the accompanying drawings and the embodiments; a big data-based learning state monitoring system of the present invention is not limited to the embodiments.
