First, the key technology of smart campus
(I) Environmental Awareness and Internet of Things
At present, the main platform for transmitting Internet of Things information is still the network, but the Internet of Things adds some information perception and processing functions to the network terminal. Perception technology generally includes laser scanning, infrared sensing and video monitoring. Different from the traditional human-to-terminal network, the Internet of Things can effectively realize the positioning of people and people, things and things, combined with recognition, management, and monitoring functions, and fully realizes the unique “smartness†of smart campuses. "Advantage."
(II) Organization and Integration of Educational Resources on Cloud Platforms
Through the organic integration of education and teaching resources with the cloud platform, it is more conducive to the integration and sharing of education and teaching resources, so as to effectively solve problems such as uneven distribution of educational resources, slow update speeds, and difficulty in sharing, and to better achieve education. Balanced development of resources. The main task of the previous digital campus is to realize the initial integration and static organization of educational resources, which is often affected by the limitations of the platform. Resource integration is more of a physical storage, but the resources themselves are relatively lacking in the logical relevance. .
(III) Mobile Internet and Applications
Essentially, mobile Internet technologies include access technologies such as self-organizing networks, 4G, and Wifi. Mobile Internet can effectively break through the limitations of wired networks that are accessed during the network access of college campuses, and fully reflects the openness of smart campuses. "feature. At the same time, the smart campus mobile internet environment supported by the wireless network has its own advantages, and its characteristics are mainly expanded, integrated, high speed, and scale. Different from the traditional network, the mobile network access terminal also has diversified features.
(D) Learning Collaboration and Social Networking
We usually define social networks as a social or social network service. It is a network service method that facilitates interpersonal communication and has the characteristics of virtualization. One of the current trends in the development of information technology is social networking, which has become a key factor in promoting the development of the Internet. At the same time, the social network also has the advantages of low cost and strong openness, and is one of the first choices for college students to display their individuality, maintain social entity relations, and express their interests.
From the perspective of application coverage, smart campus includes all applications of digital campus, and also provides users with personalized services through the addition and integration of new technologies. For example, students can complete assignment download through smart campus. Basic operations such as elective courses on the Internet, schools can limit students' online time and access content according to the timetable. Students' learning behaviors can also be analyzed and compared with other students' related learning data. According to the basic principles of pedagogy, an effective learning program is created for students and targeted and systematic learning plans are pushed to students.
From the perspective of overall planning, the smart campus mainly includes intelligent design of school activities, personalized push resources, decision assistance, display of decision-making data, mobile use of various business systems, establishment of a digital campus infrastructure platform, integration of school data, etc. main content.
From an architectural point of view, its architecture is basically similar to that of the Internet of Things, but its decision-making and data layers are not found in the Internet of Things, and can be divided into decision-making, application, data, communication, and perception layers.
II. Application Prospects of Cloud Computing and Internet of Things in the Construction of Smart Campus
(I) Application of cloud computing in the construction of smart campus
The application of cloud computing platform in smart campus includes three levels: infrastructure, platform, and application. Among them, the infrastructure layer includes important hardware such as servers, storage systems, and network systems. The platform can provide users with services such as server rental and virtual hardware resources, including data management, user authentication, and authorization. The development platform, middleware and database together constitute its platform service system. The center of the smart campus is the software service layer, and all its educational information exists at this level. In the process of building a smart campus in the future, cloud computing will play an important role. Take students' experiments as an example. During the entire teaching process, experiments are important for improving students' ability to operate autonomously, discover new areas, and acquire new knowledge. effect. However, school labs are not open every day, and it is impossible to provide each student with the opportunity to experiment at any time. Students cannot own their own laboratories. To solve this problem, the cloud computing platform can use resource sharing and remote desktop methods to provide schoolteachers and students with a client system that accesses the cloud platform, so that they can experience the convenience of high-speed operation and mass storage, thereby providing each teacher and student with a Be your own virtual laboratory. In the process of building a virtual laboratory, it is necessary to first establish a laboratory environment, build a complete virtualized resource pool, and perform operations on resource application, monitoring, and recycling in an automated manner. School teachers and students can use virtual desktops at any time. Remote access to virtual labs.
(II) Application Prospect of Internet of Things in Smart Campus Construction
Intelligent sensing is the most important feature and advantage of the Internet of Things. Smart campuses can effectively manage student safety, teaching activities, teaching resources, and campus life through the application of IoT technology, which is conducive to creating a harmonious, intelligent, convenient, and campus environment for colleges and universities. . The application of IoT in smart campuses mainly includes three aspects: campus life, teaching management, and security defense. Among them, when the Internet of Things plays a role in teaching management, the management contents mainly include smart libraries, automatic attendance management, and wisdom courses; in terms of campus life, its function mechanisms mainly include smart bathroom management, intelligent dormitory management, and intelligent canteen management; In terms of security defense, the role of the Internet of Things is even more important. It can provide technical support for the campus's security defense, making up for the shortcomings of the current lack of security in the campus, and providing comprehensive control over the school’s situation through sensor devices. When a security problem is discovered, the device can automatically alarm, which is conducive to the school security personnel's timely handling of security risks.
Third, the conclusion
Education informatization is a widespread and profound proposition. It has attracted wide attention in the current colleges and universities. However, education informatization is not accomplished overnight. It requires a long process of development. In this process, education informatization follows a certain degree. The regularity and path of the law are its main features. Relevant studies believe that initial, application, control, integration, data management, and data maturity are the six necessary phases for the development of information technology. The process of educational informatization includes the four major stages of start-up, application, development, and innovation. Each stage has a relationship that is related to each other and progressively progressive. Changes in the external environment and actual needs will continue to promote information technology to a higher level. At the stage, there is no separation and transcendence between stages, which is the basic law for the development of educational information.
Through the application of cloud computing and Internet of Things technology, the wisdom of the teachers and students in the campus is conducive to the creation of colorful campus culture in college campuses, to facilitate college students and students living, learning and work. Currently in the early stage of building a smart campus, smart campuses will gradually replace digital campuses in the near future and become the main direction for the development of educational informatization.
