The knowledge economy based on the production, dissemination, and application of knowledge and information occupies a leading position in the development of the world economy. The comprehensive national strength and international competitiveness of the country depend on the level of education, science and technology, and knowledge innovation. Education is important in the economy and society. It plays an increasingly important role in the development process. With the continuous advancement of social science and technology, the latest technology has gradually entered the campus. The rise of the network has greatly promoted the cultural construction of the campus and changed the traditional education model. Government agencies have paid more and more attention to the use of high technology to educate the next generation.

What campus network construction needs is the most cost-effective network, with excellent Gigabit Ethernet as the core of the network, and high-density Fast Ethernet as the access part, using star topology connection. This network topology not only provides The campus network is composed of powerful bandwidth and good economy.

Today's campus network should have the following functions:

1. Provide e-learning, network management, Internet access and personal dial-up user access;

2. The campus information management system should include: principal's office system, educational administration management system, financial management system, file management system, multimedia teaching system, electronic lesson preparation system, electronic reading system, score statistical analysis system, question bank and test system, library management system , Student personal management system, etc.;

3. Provide EMAIL, WWW, FTP, NEWS, BBS and other services for each customer on the network;

4. The network connects teaching buildings, office buildings, libraries, dormitory buildings and other buildings;

5. The network should have certain security considerations;

6. Network management should have simple and effective characteristics; this system consists of integrated wiring system, distance education system, digital library system, digital teaching system, network video conference system, campus service card system, electronic bulletin and information query system, Voice communication system, cable and satellite TV receiving and broadcasting system, campus public broadcasting and background music system, campus security monitoring system

1. Integrated wiring system

1. Work area system The purpose of the work area system is to provide users with a standard that complies with ISDN and meets the needs of high-speed data transmission. The system consists of an international standard information socket (RJ45) installed in each household and a terminal connection, and the data terminal is connected through the socket.

2. Horizontal system The horizontal system is composed of cables from the wiring closet of each unit to each work area. The system starts with an information socket in the work area, and consists of cables arranged horizontally to the inner distribution frame of the management area. In order to ensure high-speed transmission, the level of voice and data transmission medium in this scheme all uses Super Category 5 4-pair twisted pair to connect each information point.

3. Equipment room system The equipment room system is the central unit of the entire wiring system, which is interconnected by the cables in the equipment room, the main distribution frame and various equipment supporting the hardware system equipment. The system is connected to public system equipment (such as PABX), and carries out wiring management to each building sub-distribution frame through vertical trunk lines.

4. Building group subsystem The data, telephone, and video system cables of two or more buildings form the building group subsystem. Including building equipment room subsystem wiring equipment, outdoor cables, etc. Possible routes: overhead cables, directly buried cables, underground pipelines through cables.

2. Distance Education System LH DELP (Distance Education and Learning Platform) system is a complete class system designed for distance education and IP network education. It can simulate a real classroom on the IP network and bring voice and data functions to teachers and students. Support sound, video, data and information functions.

1. Voice support: The teacher can speak, and his voice can be heard by everyone in the class. Teachers can choose a discussion method to enable students to talk, or they can turn off some learning

Sound of life.

2. Short message support: teachers and students can send short messages to everyone.

3. File display support: Teachers prepare files before class and upload them before or during class. The files can be displayed to all students. Students can also upload files to let teachers show them to everyone.

4. Video: The teacher's video screen can be provided to every student, and the teacher's statement on the blackboard can be displayed to every student.

5. The system can support narrowbands such as 33.6kModem, and support multiple classrooms with more than 1,000 people. § It can be used in a video conference system for remote conferences to demonstrate PowerPoint, pictures and other media.

3. Digital Library System The library is the information resource center of the school, and the construction goal of the library system is the digitization of the library. The library's comprehensive information system should include functions such as electronic reading, book ordering, inventory management, book collection and indexing, audio and video production, book consulting services, and book borrowing and registration.

Fourth, digital teaching system The digitalization of the teaching system is an important symbol of a modern campus, and the system should implement an all-digital network teaching model based on the campus network. The multimedia teaching system must meet the needs of teaching activities, possess various functions of multimedia teaching, and meet the needs of distance teaching in different campuses and off-campus.

5. The network video conference system system can realize the multi-campus conference function, and the system equipment is easy to operate, simple and beautiful, and advanced.

6. The campus service all-purpose card system uses smart cards as the carrier, and through the campus network, the smart cards have identity recognition and authentication functions, campus electronic consumption functions, fee collection functions, savings functions, management functions, etc.

VII. Electronic bulletin and information query system. The system uses large LED display screens in relevant places on campus to release graphic messages, notices, announcements, etc. It can also broadcast video signals, and set up touch screens to provide staff inside and outside the school to inquire about relevant information.

8. The voice communication system can meet the communication needs of indoor fixed telephones, public telephones, mobile phones, and PHS in the campus.

9. The cable and satellite TV receiving and rebroadcasting system system can realize the ability to receive and rebroadcast urban cable and satellite TV to meet the needs of watching TV and foreign language learning and watching foreign TV.

10. Campus public address and background music system system The public address system can provide a convenient way for school information release, student area information release, and building information release. It can realize functions such as call broadcast, zone broadcast, fire alarm broadcast, etc., and background music can be played. Add a warm and comfortable atmosphere to the campus.

11. The campus security monitoring system In order to ensure the safety of all aspects of the campus, strict security monitoring measures should be set up to monitor the campus in an all-round way. The system should monitor the campus perimeter, main entrances and exits, public areas, exterior and internal key parts of the building, and alarm abnormal conditions in the surveillance area, and set up access control systems for important departments.
