Chongqing technology and business university 14, 15 and 16 student dormitories.
Design scheme of building integrated wiring system
I. Overall structure of the system
1, 14, 15, the integrated wiring system for student dormitories adopts wiring closets on the third floor respectively, and a 24-core single-mode optical fiber (considering the future development capacity of the area) is introduced from the campus network sub-center of Building 6 in the south area to the wiring closets on the third floor of Building 14. Then, a 6-mode optical fiber weak current device is introduced from Building 6. Wall-mounted cabinets (12U and 8U standard cabinets) are installed in the aisle on the third floor, which is not less than 2.2m At the same time, a 220V power socket needs to be installed beside the cabinet as the power supply for the cabinet equipment. Each data point in the building is managed by the wiring room and centralized wiring is adopted. The integrated wiring system structure of 14 and 15 floors is shown in the following figure:
2. 16 student dormitory integrated wiring system scheme: The building is117.8m long and 49.8m wide, and the building structure consists of three units. After calculation, if the centralized wiring scheme is adopted, the horizontal cable will be too long. Therefore, the wiring of the three units adopts the distributed wiring scheme, that is, each unit has its own wiring room, and one of them has a large number of information points. It is recommended to set up a distribution circuit room on each floor (to avoid the cable being too long). The other two units are set on the third floor and the sixth floor respectively according to the number of information points, and the wiring rooms are connected by grade connecting wires. Access to the campus network uses a 24-core single-mode fiber to access 1 unit from Huizhi Building (considering the future development capacity of the region), and then access 6-core single-mode fiber to unit 2 and unit 3 respectively. 16 building integrated wiring system structure as shown in the figure below:
3. CCTV system design: CCTV on 14, 15 and 16 floors are introduced with 75-9, 75- 12 main lines and 75-5 branch lines respectively, and the data points are installed according to the standards of one duty room and one roof.
Second, the overall consideration of system wiring
1, integrated wiring product selection
It is suggested that 5e cables and modules be used in some products of the integrated wiring network, and ordinary telephone cables be used in the voice part, which is implemented by China Telecom. Other network products are cost-effective.
2. The whole integrated wiring system should include three systems: network, voice and closed-circuit television.
The network system determines the number of information points according to the actual size of the room, and each standard room has 2 data points.
Each standard room of voice system 1 information point and duty room 1 information point.
Closed-circuit television system is located on the roof of each building according to 1 duty room and 1 information point.
The specific location of the information point is determined according to the mark in the figure.
Three. Distribution of information points on each floor
According to the above basic principles, the number of information points in each building is as follows:
1 and 14 have the same information points on the first to sixth floors of the student dormitory.
