This article
mentioned the campus more refers to the college campus. In fact, the campus
should also contain the campus of primary and secondary schools, technical
secondary school, technical school and kindergarten. Because colleges and
universities campus wiring is the most complex, most of the other types of
campus can according to the wiring characteristics of colleges and
universities, combined with their own actual situation to change. So for the
sake of length, for other types of campus no longer is described. Also, because
of space, in this article only carries on the overall description, without its
concrete content description.
1, use the
campus of wiring
Campus wiring
USES in fact is very simple: to satisfy information, alarm and control in areas
such as the demand for physical layer transmission equipment. A, can think of
at least include the following contents:
Meet the
needs of informationization teaching of computer network;
Meet the
students' dormitory and single faculty needs of computer network and telephone
in the dormitory, and the future demand for IPTV;
Meet the
meeting space (meeting rooms, lecture hall, auditorium, type of ladder
classrooms, etc.) to the electronic meeting requirements;
Meet the
needs of library of information transmission and storage;
Meet the
demand of the wiring entertaining nature of hotels, guest houses;
Meet sports
venues large sports meeting will be held in wiring requirements;
Meet the needs
of families of faculty, staff dormitory for wiring;
Satisfy the
school management (including shops, dining room, hospital, etc.) the need for
wiring;
Meet the
campus (especially the gatehouse, parking lot, etc.) the need for wiring;
Meet the
needs of school-run factory, training center for wiring. In addition, the
integrated wiring system transmission channels can also be Shared with other
system and realize the intelligent system of physical fusion.
In the campus
of colleges and universities, and can be as many as dozens of intelligent
system, which includes building, community, sports venues, hotels, restaurants,
shops, factories, conference, library and other intelligent building sites, so
its wiring structure also has the characteristics of combination of diversity
and professionalism.
2, the
diversity of campus wiring
Colleges and
universities campus itself is a small society, it almost contains various
places in the city (of course, there are other, such as the urban traffic,
sewage treatment, such as the weather forecast does not usually appear on
campus). So in campus construction, integrated wiring system should refer to
relevant construction type compares design, at the same time, it should be
combined with the feature of the campus.
(1) meeting space
(e.g., conference rooms, lecture hall, auditorium, type of ladder classrooms,
etc.)
Campus in the
meeting room can be found everywhere, and some can international conference,
some may hold cabaret, some can be remote television/telephone conference, some
for academic meeting, some used for discussion and vote, etc. Of course, there
are some meeting room is to provide the students freedom held various
gatherings, parties, BBS and other activities.
Meeting space
information demand and electronic meeting rooms of basic similar, install the
necessary remote video conference, simultaneous interpretation and electronic
conference, electronic voting, projection system, electronic whiteboard,
wireless local area network (LAN), electronic guidance and other equipment, can
basically meet the needs of the vast majority of meeting space. It is important
to note that most of the teachers and students of the campus is equipped with a
laptop, they probably took computer to the meeting place.
So in a few
large meeting space (e.g., trapezoidal classrooms, etc.), the laptop to get to
the Internet (such as the location of the wireless local area network (wlan)
and bandwidth selection), power supply, such as seat install socket is
installed in the front seat back below) and use the laptop question (using
conventional projector or use with RJ45 port network projector) becomes an
issue.
(2) have
almost every campus in library, modern library must be equipped with electronic
library and library management system, therefore the library should be carried
out in accordance with the wiring of the professional library comprehensive
design. In the campus library will inevitably linked with electronic teaching,
to be able to easily call the library resources, means that the library export
bandwidth can not become the bottleneck of information transmission.
(3) hotels,
guest houses
For the
reception guests, colleagues and students' families, generally have hotels or
hostels on campus, the facilities and social common star-rated hotel more than
two (sauna, massage, swimming and so on environment may not have) no
difference. This part of the wiring design can almost copied hotel wiring
structure.
(4) sports
venues
Campus sports
venues is indispensable, because of this, some of the local sports games, such
as the university games, etc.) may be placed on the campus.
If the
information construction of sports venues can satisfy the standard of sports
venue information, and can carry on the playground when the large-scale sports
meeting will be held in the network, can undertake news release, information
can be released quickly match, can be done to the best of its value. In fact,
the modern sports information construction is not high demand for wiring,
wiring costs compared to the other buildings in the campus is also very low.
(5) the staff
dormitory area of their families
Some families
are included in the campus dormitory area, some with family members outside the
dorm on campus, some campus don't consider family members' dormitory, of
course, but for staff to buy commercial housing in the society.
For a special
family, the basic information construction is similar to the intelligent
residential area. But due to the particularity of teachers' work (not
ZuoBanZhi, most of the time you can work at home), so in the construction,
should be the campus information network (mainly for the computer network)
extended to family members of the dormitory, allow teachers to high-speed
server in the campus multimedia courseware to be obtained in the home, also can
upload home-made multimedia courseware to server.
Family
members of the dormitory door, therefore, should not be regular 1 ~ 2 MBPS
bandwidth, but should reach 100 ~ 1000 MBPS, namely can do MB Ethernet or
gigabit Ethernet to the family.
(6) the
school logistics management
School
logistics management of the coal face is very wide, contain campus greening,
infrastructure construction, equipment maintenance, catering business, health
care, such as content, indispensable, of course, the student registration
management, file management of schools, as well as the school, college,
department, teaching and research section, office, branch, room of
administrative management and academic management. The management for the
integrated wiring is equivalent to the office (or office) wiring construction.
If school
self-built relational area, the relational area management is also part of the
school logistics work, this part of the management in fact belong to the
intelligent residential area property management.
Because of
the distance between the various management tend to be in the campus, many of
them have to with the aid of optical cable to realize information management of
high speed, and at the same time also in transmission on optical cable,
broadband Internet access and other various types of electronic teaching
information, the network management of relatively independent so as to prevent
the virus and hacker inside and outside the campus (including the
"red") the necessary means of attacks.
(7)
school-run factory, laboratory, training center
In order to
meet the requirements of teaching activities in science and engineering,
engineering and medical campus mostly built in various types of school-run
factories, training center and laboratory, in which the largest number of
laboratory.
School-run
factories and training center, wiring structure and basic similar factory
wiring, just because it has both the function of demonstration, so the location
of wiring and bandwidth requirements will be higher.
Most of the
laboratory of wiring and wiring similar basic classroom.
Anyway, since
the campus is like a small society, so the vast majority of wiring design basis
can refer to all types of building society. Only when the design must always
remember: this is the campus, with its different place and society.
3,
professional campus wiring
Campus, after
all, is the important place of teaching, it's a professional is also very
obvious.
(1) the
informationization teaching
In the
teaching, static multimedia courseware teaching has been very popular, also
more and more dynamic multimedia teaching courseware, which requires the campus
of wiring system to withstand very high speed of information transmission, and
for its real-time performance.
And from the
point of the information management, only will be a lot of data of multimedia
courseware, and other information stored on a handful of large, well-equipped
data center, can with the least amount of high level professional computer
management personnel to achieve high quality protection of huge amounts of
information (most of the school and department level computer room does not
have high quality environmental equipment and maintenance personnel). This
contributed to the transmission requirements of integrated wiring system.
Therefore,
needs to be laid on campus information transmission cable, extending in all
directions and the transmission bandwidth of optical fiber cable is higher and
higher. Even if is to use the most advanced full wave optical cable (that is,
the single mode zero water peak cable), that can completely meet the
information needs of a few years later.
(2) the
students' dormitory and single staff dormitory
Student
dormitory and single in the staff dormitory has reached the degree of every
computer, so in a few years ago has asked each equipped with a data point in
the dormitory, each to install a telephone information point, namely the
information point in each dormitory = total number of + 1.
It is worth
noting that the question is: there are several cities in China is the system of
IPTV and other new TV model, as the pilot scope expanding gradually, more and
more families have to smoke on demand you want to see on TV shows, you can
imagine, this trend is likely to evolve into on campus students to preview and
review the course of the basic means, could also become teachers teaching
methods of reference of the new age of learning. As a result of video-on-demand
transmission cables are different: the coaxial cable of the radio and
television use, telecom use integrated wiring and ADSL. Therefore to compare
insurance is beside the television besides equipped with radio frequency
socket, and installation of an integrated wiring information point (data
points) as the standby. In this way, no matter use what kind of transmission
medium in the campus, can ensure that students and faculty can watch on TV
programs.
(3) meet the
campus (especially the gatehouse, parking lot, etc.) the need for wiring
Campus is the
most headache wiring problems in the guard room, boiler room, substation,
parking lot (if required) monomers such as small building wiring, because
information point in these buildings tend to be only a few, and must support
telephone, computer networks, on demand TV and other equipment.
In normal
circumstances, the use of optical fiber cable and local cable is the most
mindless way, but the cost is very high. More ideally, laying type outdoor
twisted-pair from nearby buildings or short fiber optic cable to the individual
buildings.
4, the
physical fusion between intelligent system
On campus,
has many kinds of intelligent systems, but most of the use of integrated wiring
(cable and optical fiber cable, coaxial cable and control cable as transmission
medium, the physical they take up a lot of space in the campus underground pipeline
information.
If the design
can be part of the physical media on campus (e.g., fiber optic cable) to merge,
can greatly reduce the underground pipelines, Wells/hand hole and the cost of
the transmission medium. Or leave more of the pipe hole used for rental.
For example,
if you to the airport, will the campus broadcast, cable TV, video monitor and
alarm system of optical cable and information transmission cable unified
layout, based on the principle of "interference" side of the road,
each other, by adding some of the fiber optic cable, ways to reduce the number
of the root of cable, can greatly reduce the number of tube hole in a pipeline
under mainland, achieve cost reduction, convenient management goals.
Pipeline, of
course, reduce may bring optical transmission equipment (such as video optical
transceiver, etc.), therefore the integration of pipeline should be based on
the overall cost (equipment, cable, pipeline and management) decline.
5, the
conclusion
Campus wiring
is not complicated, just some trival, need to know a lot of application needs,
and the future development trend of related, together after the formation of
current wiring requirements.
A wiring way
to consider is: in the campus network with sufficient spare tube hole, with the
application demand of campus, growing phases to add more advanced information
transmission in the age of the cable (cable or cable), make the wiring is
always ahead of the application. And the implementation of this method is based
on campus network laid before have prospective prediction about the future of
the campus, and that no matter which level for wiring for the designer is the
hardest thing to do.
