Analysis on the security cabling system of Colleges and Universities

Campus cabling is actually very simple: it meets the requirements of devices in the information, alarm, control, and other fields for physical layer transmission. In primary and secondary schools, technical schools, kindergartens, and other campuses, the campus wiring of colleges and universities is the most complex. The campus of a college is itself a small society, which contains almost all places in the city (of course, there are also, such as urban traffic, sewage treatment, weather forecast, and so on are usually not displayed on campus ). Therefore, during campus construction, the Integrated Wiring System should be compared and designed based on the relevant construction types, and the specific characteristics of the campus should also be taken into account.

(1) conference venues (such as conference rooms, lecture halls, large auditoriums, and ladder classrooms)

Conference rooms on campus are everywhere. Some can hold international conferences, some can hold song and dance performances, some can hold Remote TV/teleconference, some can hold academic conferences, and some can be used for discussion and voting. Of course, some meeting rooms provide students with the freedom to hold various gatherings, parties, forums, and other activities.

The informatization requirements of conference sites are basically similar to those of electronic conference rooms, the installation of necessary remote video conferences, simultaneous translation, electronic conferences, electronic voting, projection systems, electronic whiteboards, wireless LAN, electronic guidance, and other equipment can basically meet the needs of most conference sites. It is worth noting that most of the teachers and students on campus are equipped with laptops and they are likely to bring their computers to the conference venue.

Therefore, in some large conference venues (such as trapezoid classrooms), laptop computers are connected to the Internet (such as wireless LAN layout and bandwidth selection) power Supply (such as socket installation under the seat is still installed in the back side of the front seat) and use a laptop to ask questions (using a conventional projector or using a network projector with RJ45 ports) has become a noteworthy issue.

(2) Library

Almost every campus has a library, and the modern library must be equipped with an electronic library and a library management system. Therefore, the library should be fully designed according to the wiring requirements of professional libraries. The library on campus will inevitably be associated with electronic teaching. To make it easy to call the library resources, it means that the library egress bandwidth cannot become the bottleneck of information transmission.

(3) hotels and guest houses

In order to receive visiting VIP guests, colleagues and family members of students, there are usually hotels or guest houses on campus, there is no difference between the facilities and common two-star hotels (which may be unavailable in the sauna, massage, swimming, and other environments. This part of the wiring design can almost copy the structure of the hotel wiring.

(4) Stadiums

Sports Venues on campus are essential. Because of this, some local large-scale sports meetings (such as college sports meetings) may be placed on campus.

If the informatization construction of sports venues can meet the informatization standards of sports venues, the sports venues can be connected when a large sports meeting is held, news can be published, and competition information can be quickly published, you can do everything you want. In fact, the information construction of modern stadiums does not have a high requirement for wiring, And the wiring cost is also very low compared with other buildings on campus.

(5) dormitory area for members of the faculty and staff

Some campuses contain dormitory areas for family members, while others have dormitory areas for family members outside the campus. Of course, some campuses do not consider dormitory areas for family members, but allow faculty and staff to buy commercial houses in society.

For the dormitory area of family members, its basic information construction is similar to that of Smart Community. However, due to the special nature of teachers' work (non-shift, most of the time can work at home), Campus Information Networks (mainly computer networks) should be used during construction) extended to the dormitory of family members, allowing teachers to quickly retrieve Multimedia Courseware on campus servers at home, or upload self-made multimedia courseware to the server.

Therefore, the household bandwidth of the residential dormitory should not be 1 ~ 2 Mbps, but 100 ~ 1000 Mbps, that is, Mbps Ethernet or Mbps Ethernet to the home.

(6) School Logistics Management

The school's logistics management work surface is very wide, including campus greening, infrastructure construction, equipment maintenance, catering business, health care and other content, of course, the management of student status management and school archives is indispensable, administrative and academic management of schools, colleges, departments, teaching and research sections, departments, departments, and offices. Such management is equivalent to cabling of an office (or office) for integrated cabling.

If a school builds its own family area, the family area management is also part of the school's logistics work. This part of management actually belongs to the Smart Community Property Management.

Because the distance between various management departments on campus is often far away, many of them must use optical cables to achieve high-speed information management, the optical fiber also transmits various types of information, such as electronic teaching and broadband Internet access. Therefore, the management network is relatively independent and thus Prevents viruses and hackers (including "Hongke") inside and outside the campus ") necessary means of attacks.
