Through the in-depth mining and analysis of the existing smart campus data using big data technology, based on the support of intelligent decision-making, personalized adaptive learning analysis and campus security warning of big data, and using the results to feed back the improvement of information literacy of university teachers and students in the era of big data, the construction of ubiquitous learning environment is carried out, which points out the direction for the construction of ubiquitous learning environment to explore the role of big data in improving the quality of education, promoting educational equity and optimizing educational philosophy, so as to improve the ubiquitous education environment.


Introduction
With the rapid development of Internet and information technology, ubiquitous learning has become a basic learning form. Ubiquitous learning breaks the boundaries of time and space of traditional learning, and expands the learning time from traditional classroom to spare time, thus realizing the transition from large-scale to discrete learning behavior. Ubiquitous learning is closely related to big data. Big data has achieved great success in the field of business and sociology (Zhou, Kang, & Gao, 2020). Ubiquitous learning environment provides a good solution for these problems. The emergence of big data technology provides a new solution for the development of ubiquitous learning. Through in-depth analysis of big data demand and operation in ubiquitous learning environment, this paper analyzes education big data, carries out information resource construction, establishes research model, obtains the results and puts them into practice. Finally, it uses the results to feed back the improvement of information literacy of college teachers and students in the era of big data, points out the direction for the construction of ubiquitous learning environment and colleges and universities in the new era to provide advanced experience in talent training.
Through the analysis of the existing smart campus data using big data, using a variety of high-quality information services provided by big data, we can construct the ubiquitous learning environment, improve the ubiquitous education environment, provide data support for the evaluation and improvement of scientific decision-making, students' learning and teachers' teaching, and provide data direction for the reform of classroom teaching ecology (Jin, Zhang, Ba, Song, Yang, & Song, 2019). Through the exploration of personalized teaching relying on big data technology, colleges and universities will be promoted to a new level in teaching, scientific research and management innovation.

The Impact of Current Higher Education
The rapid development of Internet and information technology has brought great impact on education. At present, big data is sweeping the field of education, which has brought great changes to human learning, making the learning mode from digital learning to ubiquitous learning. In Colleges and universities, students, teachers and teaching environment are receiving the impact from all directions (Xia & Cheng, 2018). For example, the change of educational object, the change of teacher's role, the change of teaching environment and so on. The network has brought a diversified teaching environment, and student education is developing rapidly in the direction of informatization and socialization.

Upgrading of Wireless Network
The construction of wireless network signal is the basic guarantee of ubiquitous learning. In order to provide convenient communication services for teachers and students to access campus network resources, and provide basic communication guarantee for the development of mobile informatization in Colleges and universities, it is urgent to upgrade the original campus mobile wireless network to campus wireless network, which initially realizes the campus wireless signal access. In order to further improve the quality of wireless signal, the wireless coverage, access speed and total exit bandwidth of wireless network are up-graded. Through upgrading and transformation, the wireless signal coverage of the Campus Office, teaching, experiment and student accommodation area is basically realized.
Through the upgrading of wireless network, the quality of wireless network has been greatly improved, and the capacity of wireless network has been basically realized to meet the requirements of high-speed development of university teachers and students. Within the coverage of campus wireless network, faculty can access the campus Internet and campus network resources for free, and students can access campus network resources for free. Users who have opened China mobile wireless account can access mobile Internet and campus network resources in the above areas through campus network account after completing the binding of campus network account and mobile terminal account. Students can visit the campus resource platform and search information on the Internet free of charge at any corner of the campus and at any time through the mobile terminal. The penetration of wireless signals also provides convenience for students' communication, which provides fertile ground for the implementation of ubiquitous learning.

Intelligent Authentication
Intelligent authentication (which is also called imperceptible authentication) is a kind of automatic identification and authentication system by the terminal. Users only need to pass the successful authentication once, and the wireless terminal equipment can automatically record the account information. After that, as long as there is no need of authentication within the coverage of wireless signal, the network can be normally accessed. Imperceptible authentication is an intelligent experience way of wireless network application. Portal protocol authentication is one of the most popular authentication methods, which has some advantages in compatibility. In the process of portal authentication, after the user accesses the network and obtains the address, the gateway will redirect the user who is not authenticated to the authentication portal. The user can directly authenticate through the browser, and then access the network resources after the authentication is successful. It can realize the access and exit of the network.
The implementation of intelligent authentication in Colleges and universities avoids the cumbersome repeated login, greatly improves the user experience, and increases the convenience of ubiquitous learning.

Big Data Laboratory Environment Construction
The construction of big data laboratory environment includes hardware and software. The hardware consists of server, terminal computer and other corresponding supporting equipment. The server is the core hardware platform for the construction of big data laboratory. It not only provides sufficient storage space, memory space, cloud computing resources, mirror scheduling and other resource support for the accumulation of big data laboratory achievements. The The big data laboratory software introduces the big data experiment platform of New Cape, including cloud computing management system, big data course management system, big data online experiment system and big data cloud storage system. Cloud computing management system is mainly used to monitor the total resource usage of cloud server in real time, as well as the management and operation of mirror warehouse usage.
The big data course management system sets up course contents corresponding to big data, such as Hadoop, R language, python, etc., and can also create new course contents.
The big data online experiment system provides big data experiment cases and supporting experiment manuals. The system is embedded with a variety of big data development environments, including a variety of big data experimental courses.
Big data cloud storage system is mainly for the management of user storage space, which can upload, download and manage various types of files.

Teaching Big Data Collection and Analysis
Big data provides a forward-looking perspective and direction for the reform of education mode, making it more scientific and innovative. Teaching based on big data is more conducive to personalized development, enrich learning content and improve learning efficiency. The application of big data technology to analyze and measure the learning characteristics of students, through rational data analysis, can have a great impact on the reform and innovation of teaching mode.
Exploration on the application of big data in teaching, finds the relationship between data and draws conclusions.
