Under the education concept of new era, colleges and universities need to focus on cultivation of students’ mental health besides the necessary quality education. Effective planning and decision-making of mental health education help students establish correct outlook on life and values, with great significance on their comprehensive development. With the rapid development of science and technology, data mining technology has been gradually applied to cultivation of students’ mental health. The work focused on the application of data mining in mental health education of students. Through rational application of data mining technology, the current models of mental health education for college students were further improved to provide reference for future mental health education.
At present, in the process of talents training in the application of information engineering, there are some phenomena in the school-enterprise cooperation, such as "universities are active, enterprises are not active", the cooperation level is shallow, and the matching degree between talent output and enterprise talent demand is low. In view of these phenomena, a new training mode of information application engineering talents is put forward that base on the deep integration of school and enterprise that take the project as carrier. The paper expounds its connotation, significance and concrete construction ideas and measures. Practice shows that the model can effectively promote school-enterprise integration and collaborative education, improve students' engineering application ability, innovation and entrepreneurship ability, improve students' employment competitiveness, and improve the matching degree of talent output and professional posts.
Adopting STC12C5A60S2 single-chip microcomputer as the control core, the access control system of a safe with multiple password control consists of fingerprint recognition, GSM-SIM900A, 24C02 storage, LCD12864 liquid crystal display, motor drive, keyboard, and sound-light alarm modules. Experiments showed that the system could accommodate 200 fingerprint data. The fingerprint recognition time was less than 0.4s; rejection rate less than 1%; and false recognition rate less than 0.001%. After passing digital password and fingerprint identification, the system sent a verification code to the user's mobile phone. When the code was verified, the system started stepping motor to open access control. The system entered frozen state with sound-light alarm if the error of digital password or fingerprint identification was three times. The alarm was sent to the user's mobile phone at the same time. The system had the functions of multiple password protection, remote monitoring and alarming, with a high security and practicality.
