First, the construction background
Before the implementation of the agricultural project, the route of the campus network of Pukou No. 2 Middle School was relatively old, and the cable quality was poor. Most of the lines were supplemented before 2007. The fault of the network cable can only be solved by privately pulling the outside line. Due to the original design problems, some teachers' offices can only rely on several small switches to develop one layer at a time. The school's wireless is even more difficult to talk about, basically using a home router instead. Even the integrated building that has just been put into use for two years is the infrastructure wiring of the early years and does not meet the specifications. In addition, the information center has no decoration and is used in the embryo room.
The construction goal of this network data center is to re-route all the information points of the school. The data center environment construction should realize standardized power distribution, lightning protection grounding, glass partition, ceiling and anti-static floor standard configuration, increase core switch and partial connection. Incoming switch. Especially in the wiring construction process, it is necessary to pay attention to standard construction, clear wiring and neat line markings, which is convenient for later maintenance and management.
Second, the technical framework
Six types of unshielded twisted pair cables are used for voice and data in the data center.
Cabinet system: The cabinet adopts a 19-inch standard floor cabinet with an environmental control system to maintain the indoor temperature.
Set the temperature value and remote monitoring.
Decoration system: laying anti-static composite raised floor, connecting 6mm2 wire to ground, and laying plastic floor mat. The space under the floor is used for laying electrical lines, the floor support is made of a pressure equalizing base base, and a pressure equalizing copper strip is installed. The floor grounding cable is made of 10mm2 wire, and the floor of the load-bearing part is supported by the floor. The ceiling is made of micro-aluminum gusset plate with dark keel ceiling, grounded with 6mm2 wire, and the upper space is used for laying electrical lines.
Lighting system: The top lighting uses 600*600 LED grille lights.
Lightning protection system: The central total distribution switchgear adopts Schneider 24-circuit distribution box and is associated with a lightning protection device. At the same time, the network management center is equipped with fire-fighting equipment to ensure the safe operation of the whole machine room.
Third, maintenance and management
Network data centers have certain technical complexity, and managers are often served by teachers of information technology disciplines. As a rural school, before the implementation of the agricultural project, our school was negligent in the management of the information center, and the fault response was weak. With the continuous development of school information, the task of management will become increasingly heavy. At present, the management personnel of the school network management center are concurrently served by two information technology teachers, and the “Network Management Center Management System†has been issued. The management personnel are strictly managed and used according to the system. At the same time, the system main control interface can be directly connected to the real-time feedback system of the data center operation status of Nanjing primary and secondary schools to achieve effective management.
Fourth, the use of effects
After the successful upgrade, the school's network center has been put into use, standardized integrated wiring system, data center environment system, lightning protection system and storage system, bringing great convenience to education and teaching management activities. Whenever the school organizes large-scale activities, there are more off-campus personnel or parents to participate in the school, the school will open up the Internet access channel, no longer use the home router for simple splicing; the teacher office has also fully realized wireless coverage, if there is an Internet failure, through the network management When the center finds the information point in the background, it can be directly excluded. When the network is crowded, the platform can detect whether the congestion is too large or the amount of data for viewing the video is too large.
As the first phase of the agricultural project project, our school's information education has just started, and the level needs to be improved. I believe that in the near future, with the care and support of the leaders of the city, district and school, the information education level of Pukou No. 2 Middle School will surely achieve a new leap and take off!
