Innovative research of dynamic monitoring system of mental health vocational students based on big data

The advent of the era of big data has changed the way people think and at the same time has brought opportunities and challenges to the innovation of the dynamic monitoring system for the mental health of vocational students. Traditional mental health education research is easily interfered by external factors, and investigation activities are also restricted by time and place, which affects the results of our country’s dynamic analysis of students’ mental health and delays the progress of our country’s mental health education research. Big data has the characteristics of huge data volume, low value density, complex types, and fast update speed. It can more objectively reflect the true situation of all respondents, break the traditional space limitations, save research costs, and improve research. It effectively solves the shortcomings of traditional mental health research. This article researches the innovation of the dynamic monitoring system of vocational students’ mental health based on big data, deeply learns the existing related academic research results, explains the relevant characteristics of the big data background, and establishes vocational students based on the background of big data, mental health archives, and mental health dynamic monitoring system, using the SCL-90 symptom self-rating scale to compare the gender differences, single-child vs. non-independent, urban-rural comparison, and other dynamic monitoring data research of mental health under different objective conditions. It is concluded that in the student test of this higher vocational college, there are 470 people with a total score of SCL-90 ≥160, a detection rate of 33.16%, and 146 people with a total score of 200 or more, with a detection rate of 10.30%, positive. There are 54 people with items ≥ 43, the detection rate is 3.81%, and the total score distribution is basically a normal distribution. This shows that a small number of vocational students in this school have serious psychological problems.
