The hottest school network scheme

Abstract: This paper generally explains the needs, construction ideas, design principles, network structure, technical direction and equipment selection of Xiantao education "school to school" network

key words: comprehensive information optical fiber network system broadband access campus construction Untitled Document Xiantao City is located in the southeast of Hubei Province, about 113 ° 18 'east longitude and 30 ° 50' north latitude, adjacent to the Yangtze River in the south, Hanshui River in the north, and 82 kilometers westward along Wuhan Yichang high-grade highway. It has entered the city directly under the jurisdiction of Hubei Province, which is called "the Pearl of the river and the Han Dynasty, the treasure land of central Hubei" by Wang cuifen, Secretary General of the professional committee of waterproof materials of China Construction Association, Xiantao City ranks first among the top ten in the province in terms of comprehensive strength. The construction of "school to school connection" network is the foundation of the comprehensive information network of education and the key to carry out the comprehensive broadband service of education. The comprehensive information of "school to school connection" of Xiantao education is composed of urban and rural optical fiber network system, broadband access sub project and campus construction sub project. The following are the constituent technologies of campus construction subproject. As a kind of information applied in primary and secondary schools, the campus network of primary and secondary schools has its specific meaning and application scope, which can be summarized into four typical applications: first, the campus serves students' learning activities and is a learning tool. She is not only a communication tool between students and others, but also a provider of learning resources, which is conducive to students' exploratory learning and collaborative learning. Second, the campus serves teachers' teaching and scientific research activities, such as providing teaching resources, assisting teachers in preparing lessons, participating in classroom teaching activities and supporting teachers' relearning activities. Third, the campus serves the school education and teaching management, such as student status management, personnel management, financial management and so on. Fourth, the campus is a window to communicate between the school and the outside world. Using it, you can not only obtain various information from outside the school, but also release various information to the outside world. To sum up, we can define campus as a local network environment in campus that serves school learning activities, teaching activities, scientific research activities and management activities. And it is built on multimedia technology and modern network technology and connected with Internet

for campus construction, its application is the purpose, network environment is the foundation, network teaching resources are the core, and personnel training and network maintenance are the guarantee. To evaluate the success of a campus, we can consider the following four links (hereinafter referred to as the four elements of campus network): Network Environment construction, network unblocked guarantee mechanism, network teaching resources and network application. Therefore, when designing a campus, a school should also consider these four links, which are indispensable. The traditional network construction only refers to the construction of network environment, ignoring other links

at present, the construction and application of campus is regarded by more and more primary and secondary schools as the key to achieve teaching reform and improve teaching quality to meet the needs of the times for talent training. However, many primary and secondary schools' planning for campus construction is incomplete, only staying at the bottom of the hardware environment stage, so it is inevitable to cause all kinds of problems we see today. For example:

· pay attention to hardware investment and despise software resource construction. According to the relevant survey, most of the computer education funds are invested in the computer hardware environment, the investment in software is far lower than that in computer hardware, and the investment in teacher training is very small. Many schools spend millions or tens of millions on network hardware facilities, but refuse to spend money on the construction of various software resources (such as teaching platform, school business management system, various multimedia teaching courseware, information database, etc.), resulting in a serious lack of software resources

· inefficient use of campus. Due to the neglect of software resources construction and teachers' computer technology training, the built campus equipment is idle, no one uses it, and no resources are available. Computers are only used as ordinary word processing tools. The campus is simply a kind of decoration, which does not give full play to its due role, and the use efficiency is extremely low

this paper discusses the strategy of campus network construction from four aspects: campus network environment construction, campus network guarantee system, teaching resources and campus network application. Its purpose is: first, grasp the correct direction of campus network construction from a macro perspective, and formulate effective implementation plans for construction, protection and use; Second, on the micro level, we should ensure the smooth completion of the campus and play its due role, so as to achieve the ultimate goal of promoting teaching reform and cultivating talents needed by the information society. 2、 Basic framework of primary and secondary school campus

the basic framework of primary and secondary school campus can be determined according to the four typical applications of primary and secondary school campus. This is mainly because customers do not know clearly about fixture materials when choosing. It is a local network system composed of several multi-function classrooms, several computer network classrooms, a virtual library, an office, an information center and some other applications, It is connected to the Internet through a border router. Campus is not a self operating and self closed system, nor is it a fully open system to Internet, but a relatively independent network system in the process of exchanging information with the outside world. Among them, school office, virtual library, electronic lesson preparation room and computer network classroom are generally a small local area, which is composed of one (or more) servers and several computer workstations

II. In the basic framework of primary school campus network, virtual library stores a large number of books and materials in the form of digitalization on the resource server, or provides various multimedia information resources through video server. Students and teachers can easily query, retrieve and use information through computer network

· electronic lesson preparation room

provides teachers with an environment for curriculum design and development using network resources and various tools. It is composed of acquisition and compression system, image processing system, CD making system, teacher lesson preparation system, server and several multimedia computers

· school office

through the comprehensive information management system running on the campus, the school's teaching management and daily management generally require the manufacturer to carry out after-sales door-to-door maintenance, so as to realize the automation of office automation according to its conversion principle, including binary slope method, integral method, parallel comparison method, voltage 1 frequency conversion method and successive comparison method, such as student status management, curriculum arrangement, personnel management, financial management, fixed asset management, etc, At the same time, information can be released on

· other applications

such as campus card system, use campus and smart card (IC card) technology to form a complete campus card system within the school. Through an IC card, you can be a student
