Foreword
Digital Campus Introduction
1. Definition of digital campus
The Campus Computing Project, a large-scale research project initiated and hosted by Kenneth Green, a professor at Claremont University in the United States in 1990, was the first to emerge from the concept of digital campus.
Digital campus: Based on digital information and network, the collection, processing, integration, storage, transmission and application of campus information such as teaching, scientific research, management, technical services and life services are established on computer and network technology. A virtual educational environment in which digital resources are fully optimized. Build a digital space on the traditional campus by implementing all digitization from the environment (including equipment, classrooms, etc.), resources (such as books, lectures, courseware, etc.) to applications (including teaching, learning, management, service, office, etc.) In order to expand the time and space dimensions of the real campus, improve the operational efficiency of the traditional campus, expand the business functions of the traditional campus, and finally realize the comprehensive informationization of the educational process, so as to achieve the purpose of improving management level and efficiency.
2. The significance of building a digital campus
Digital campus construction takes information resources and information services as the core content, realizes digital learning, teaching, research and management, creates digital living spaces, creates virtual spaces, and realizes educational informationization and modernization.
The construction of digital campus is not a purely technical work, but a human engineering. It introduces advanced information technology into teaching, research, management and service activities to improve the quality of teaching, learning and management. Efficiency, creating new education and work models, and accomplishing the goals that are difficult to achieve in traditional education models. The process of educational informatization is the process of transforming educational thoughts, educational concepts, and educational models.
In the context of the informationization of the education industry, the level of digital campus construction not only reflects the degree of education informatization, but also reflects the level of decision-makers' forward-looking development of modern education; it is also a measure of the school's ability to run schools and the level of teaching and research. One of the important criteria.
I. Background, current situation and necessity
1.1 Project construction background
1.1.1 Introduction to the construction unit
Beijing Water Conservancy and Hydropower School is a state-run ordinary higher education school approved by the Ministry of Education. It is the first kindergarten higher education college in Hebei Province. It is the main task of the school to train pre-school education teachers. Hebei Preschool Teacher Training Center, Shijiazhuang Teacher Training School, Shijiazhuang Preschool Teacher Training Base, Hebei Preschool Children's Psychological Education Association and Preschool Education Research Institute are all located in our school.
The school is located in the western high education district of the provincial capital. It enjoys convenient transportation, beautiful environment and strong cultural atmosphere. It has unique geographical advantages and superior economic and cultural environment. The school covers an area of ​​500 mu, with a construction area of ​​120,000 square meters. The total value of teaching instruments and equipment is nearly 30 million yuan. There are 575,000 books in the library and 1,478 newspapers and magazines.
The school has 360 faculty members, 85 senior titles, 94 masters, 4 special teachers, and more than 4,000 full-time students. The school has 20 laboratories, 7 computer rooms, 18 multimedia classrooms, and 1 electronic reading room.
1.1.2 Construction background
Our school campus network was established in 2008, and the school information construction is in a serious lag state, which has greatly affected the development of the school. In view of this, in 2014, the school decided to focus on the reform and development of education and teaching, and strengthen and promote the construction of information technology in the spirit of reform and innovation. Efforts will be made to solve the construction of the campus information system and the entire campus wireless network.
1.2 Status of information construction
At present, the school campus network adopts Gigabit fiber-optic Ethernet network, and two core switches, eight aggregation switches and 40 access switches form a three-level architecture. Gigabit Ethernet fiber connection is used between the central equipment room and the aggregation layer, and the aggregation switch is connected to the access switch. Each floor uses 100Mbps to switch to the desktop. The center currently has 7 servers, which provide services such as FTP, Web publishing, and various application software systems. The external link uses fiber-optic line, the bandwidth is 150 megabytes, and it is equipped with a fixed public network IP. It applies for a separate domain name. The server is disconnected from the machine for 7×24 hours. It is equipped with a disk array system and a 10KVA UPS power supply system to ensure the server room server. And the power supply of the switch.
1.2.1 Lack of a unified interface between various systems
The informatization construction of the whole school cannot be unified, and all departments, departments, and functional organizations have their own battles in information construction. Some departments have established their own management information systems. Due to the inconsistency of the software systems used and the inconsistency of data standards, a number of information islands have been artificially formed throughout the school, which has led to a large number of redundant construction and waste of funds. It also brought great trouble to teaching and scientific research.
1.2.2 Lack of a unified application platform, unable to achieve unified resource sharing
At present, all departments of the school have a variety of management information systems, and these systems have different sources, different data types, resulting in the duplication of most shareable data, becoming a typical information island. Therefore, it is urgent to build a unified application platform at the school level to achieve the unity and sharing of resources.
1.2.3 Lack of information standards, affecting the expansion and promotion of network applications
After the reforms of the school in recent years, all functional departments have formulated standardized procedures to make the work follow the rules. However, in the process of management work, things that change the workflow due to human factors still occur. At the same time, although the school has standardized the staff code, the more complete information standards have not yet been built. The existence of this phenomenon has brought many problems to the sustainable development of information construction.
In order to solve the above problems, the school digital campus project needs to combine the school's software and hardware construction under the overall planning guidance, closely connect with the external information world, provide a good information environment for teachers and students, and let the informationization play an active role in teaching and scientific research. Therefore, the school will be further established as a benchmark for the informationization of secondary vocational education.
1.3 The need for problems and transformation
1.3.1 There is a problem
1 New students' data cannot be synchronized to various departments in time, which makes it difficult for all departments to work effectively.
2 Changes in student status, personnel changes, lack of information, resulting in financial revenue and expenditure loopholes
3 The information of the student office and the logistics department is not uniform, and it is difficult for students to deal with unexpected situations.
4 There is a lack of data display and sharing requirements based on comprehensive information query and decision analysis based on the school multi-service system.
5 The system application of each department is cumbersome, and the login account password is too much, which is inconvenient to use.
6 Lack of personalized information services.
1.3.2 The necessity of transformation
From the above construction background and status quo, it can be seen that in the past few years, the school mainly researched and purchased some necessary application systems to meet the basic office and teaching requirements. However, with the increasing demand for information applications in schools, the contradiction between the application system and the current application system has become unavoidable. According to the two-step network construction policy, the school has completed the transformation of the network hardware infrastructure in 2010. If the application system construction cannot be followed up as soon as possible, it will inevitably cause waste of network resources and seriously restrict the pace of school information development.
Since 2005, most schools across the country have been actively promoting the intelligent construction of digital campuses, card and campus networks. The main contents of the construction include: unified identity authentication, unified management platform, unified data standards and specifications, unified portal, single sign-on, maximizing the integration of application systems of various departments, and implementing various teaching management from the school as a whole. application. At the same time, the Ministry of Education and the Municipal Education Commission are also actively guiding and promoting the informatization and digital campus construction of colleges and universities. Beijing Water Conservancy and Hydropower School is a state-run ordinary higher education school approved by the Ministry of Education. It is the first kindergarten higher education college in Hebei Province. It is the main task of the school to train pre-school education teachers. After years of development and construction, the school has already possessed the prototype and foundation of the digital campus. It should be rationally planned and scientifically constructed to make it a strong support for school development. Therefore, schools are in urgent need of a complete, integrated digital campus solution.
Second, the construction goals and significance

Third, the construction plan
3.1 Construction principles
The school's digital campus construction project is based on unified leadership, based on the principles of overall planning, step-by-step implementation, standard unification, resource sharing, and application. It is planned, scientifically and rationally constructed, and realizes the high starting point and large-scale of the school digital campus project. Leaping Development.
In the process of construction, the whole school must unify the thoughts and work together, coordinate and coordinate in the aspects of planning and design, construction and implementation, publicity and publicity, personnel training, promotion and application, management and maintenance, and system construction. It must accurately meet the practical application of the school. Demand, focusing on the construction of digital resources, promotes institutional innovation and management innovation through organizational and business process reengineering; must pay attention to the construction of information standard system, adopt the model of hardware cluster, data concentration and application integration to realize school networking, Standardized, integrated information resource sharing.
The platform and application system built by the school's digital campus project is only part of the school's long-term information planning. It is necessary not only to provide a solid foundation for the follow-up campus information construction, but also to constrain our work from the planning principle of system engineering in order to ensure the smooth progress of the follow-up construction. Based on this, the principles of the school digital campus project construction are proposed:
1. Consistency
The school's digital campus project solution, which is different from the scattered workshop-style campus network, is the systematic and holistic nature of digital campus planning and design projects. The premise of the school's digital campus project on the basis of this phase of the project to carry out future expansion projects is still a unified database platform, which ensures the consistency of the early and late projects.
2, the focus
The focus of the school's digital campus project is very important. On the basis of standardizing the interface and integration standards of the school digital campus project, our school plans to focus on the operation and maintenance of the application system, the secondary development of the product and the management of the system.
3, scalability
Scalability is one of the salient features of the school's digital campus project. Although the secondary development work in the later period can meet the complex business needs of the school, it is certain that the business needs of the school will never be exhausted. For this reason, the digital campus overall solution will continue to expand in the future. In the work, will always maintain the balance of various standardized specifications and interfaces, so that the system has more powerful support and tenacious vitality.
4, practicality
The construction of this project should fully consider the existing business system and basic environment within the school. It should be based on the mode and characteristics of the internal management of our school, so that it is functionally complete, easy to use, practical and efficient.
5, advanced
The construction of the project should be based on the advanced and promising technologies in the world today, and the system should be able to smoothly upgrade with the development of information technology in the future;
6. Openness and standardization principles
The system should be built using an open platform with open architecture, open standards, and in line with industry mainstream technical standards.
7, security
The construction of the system should have a sound security system structure. In the system design, we must fully consider the sharing of information resources, but also pay attention to the protection and isolation of information resources. Different measures should be taken for different applications and different network communication environments, including user security and data security. , operational security, etc.
8, reliability
While considering the advanced nature and openness of the technology, it is also necessary to start from the aspects of system structure, technical measures, system management, etc. to ensure the reliability and stability of the system operation, and there can be no single point of failure.
9. Manageability and maintainability
The system platform is a relatively complex system composed of multiple parts. In order to facilitate the daily operation and maintenance of the system, the system is required to have good manageability and maintainability.
3.2 Construction ideas
According to the understanding of the digital campus, the construction of the school digital campus project is a continuous process. Due to the characteristics of the school business, new applications will be integrated in the later stage. Therefore, it is necessary to consider how to easily add, change and integrate new applications in the later stage of construction, and these newly integrated applications should be able to form a unified system. At the same time, according to the actual needs of the school, considering the different characteristics, importance, impact and maturity of each business, the implementation will be focused.
There are many school departments and businesses. Therefore, in the construction of digital campus, the current international mainstream, mature technology and advanced design concepts should be adopted, so that the whole system has strong expansion capability and customizable ability, which is easy to maintain and Secondary development, saving time and investment in later construction.
The overall idea can be summarized as follows:
1. Digitization of campus resources
In the construction of various levels of systems, the digitization of resources is always running through. The degree of digitization of resources reflects the application level of each system and also represents the degree of construction of digital campuses. In the construction of digital campus, existing non-digital resources need to be digitized, and new resources are digitally added to the unified database platform. Therefore, it is necessary to establish a long-term system and mechanism for digital resource integration.
2. Standardization of digital information
Certain standards should be followed in the construction of digital campuses, especially the standards for public information. When constructing an information management system, all departments can only use the unified information standards to enable data sharing between application systems built by different departments.
3. Unification of application systems
In order to facilitate the integration of application systems in a digital campus and to establish a reasonable distribution and architecture of application systems, it is necessary to develop standards for application systems, adopt a unified database platform, development environment and operating environment, and establish a global data dictionary and view. Digital campus management organization coordinated management.
4. Integration of digital resources
The digital campus includes the hardware environment (the basic platform of the digital campus, application system, information resources and human resources) and the software environment (the organizational structure of the digital campus construction project, project investment, comprehensive management, the attitude of teachers and students to the digital campus, etc.) More emphasis on informational teaching, research, management, and service behavior. Therefore, the digital resources based on the information management platform should be integrated and integrated information, and provide a basis for school leadership management and decision-making through unified database platform storage.
5. Promote the development of network basic services with applications
Campus network construction generally starts from the network infrastructure. With the improvement of service requirements, especially the development of value-added and extended services, the software system in turn puts higher requirements on hardware, and proposes the underlying software development platform and support system. New requirements, these require new developments in hardware and software infrastructure. To establish a truly digital campus, you must plan, build, and manage server hardware and software resources to meet the requirements of system management, system security, data sharing, and cost reduction in multi-layered three-dimensional services in campus networks. Achieve higher performance digital services through application-driven infrastructure construction.
3.3 Construction Planning
3.3.1 Phase I Planning
This stage is the basic platform construction and integration stage of the digital campus. It is the most important stage in the process of realizing the digital campus. At this stage, the unified information standard of the school should be formed. All the application systems of the whole school should follow this standard in the future; It is also necessary to achieve the purpose of information resource integration in the whole school. The original system of the school should be integrated into the platform. Each teacher and student can have access to all the systems that have access to the school with only one account. The office automation system builds a teaching resource system that is compatible with the platform and the construction of some key application systems.
