The management between the integrated wiring equipment and the incoming line

Equipment room

Equipment is the intelligent building of the telephone switch equipment and computer network equipment, as well as building wiring equipment (BD) installation location, but also for network management site. For the integrated wiring system engineering design, the main equipment between the installation of the total wiring equipment. When the communication (information) facility is set up separately from the wiring device, consideration should be given to the requirement of length limits for equipment cables, so that the distance between the devices installed with the total wiring racks and the devices that install the user's telephone switch and the computer host is minimized to reduce cable length and improve transmission quality.

A standard rack (cabinet) of 5 19 inches can be installed if a device is 10m2 calculated between devices. Can install the telephone in the cabinet the large logarithm cable many pairs of card connection module, the data backbone cable wiring Equipment module, can support the building wiring equipment installation space which the total quantity is necessary for 6,000 information points (in which the telephone and the data information point each Occupy 50%).

National Standard GB50311 12,007 the following regulations are required for the installation process between equipment.

1 The location of the equipment should be based on the number of installation, size, network composition and other factors, comprehensive consideration to determine.

2 in each intelligent building to set up at least 1 units, if the telephone exchange and computer network equipment installed in different locations or according to network security needs, can also set up 2 or more than 2 equipment, to meet the different business equipment installation needs.

3 The design of the equipment is more broad, for this reason, should meet the following provisions and related professional requirements.

① devices should be located in the middle of the backbone subsystem, and should consider reducing the transmission distance of the backbone cable and the number of cables to save the investment in engineering construction.

The location of the ② equipment should be as close to the cable shaft or near the building as possible, which is advantageous to the introduction or connection of the trunk cable, and facilitates the construction and maintenance.

The location of the ③ equipment is convenient for grounding the equipment.

④ equipment should be far away from high and low voltage distribution, motor, X-ray, radio emission and other electromagnetic interference sources exist in the site, must be required between them to achieve or greater than the minimum net distance of the provisions to reduce the electromagnetic disturbances on the communication (information) impact.

Indoor temperature of ⑤ equipment should be 10℃~35℃, relative humidity should be 20%~80%, and should have good ventilation condition. More Wonderful content: http://www.bianceng.cn/Network/zhbx/

⑥ equipment should be equipped with adequate equipment to install space, the use of the area should not be less than 10MZ. This area does not include the user-controlled program switches, computer network equipment and other facilities required for installation equipment area.

⑦ equipment should be avoided with columns and other structural elements, if there is a beam, the net height should not be less than 2.5m. The door width should not be less than 1.5m with the open double door.

4 equipment should prevent harmful gases (such as chlorine, carbohydrates, hydrogen sulfide, nitrogen oxides, carbon dioxide, etc.) intrusion, and should be good dust-proof measures, dust content limit should conform to the provisions of table 2.36. The dust particles referred to in the table shall be non-conductive, non-ferrous and non corrosive.

5 in the area of earthquake, equipment installation should be in accordance with the requirements of communication equipment aseismic design code for seismic reinforcement.

6 communication (information) equipment installed in the equipment should comply with the following provisions.

① Rack (cabinet) in front of the clearance should not be less than 800mm, rack (cabinet) behind the clearance should not be less than 600mm, in order to facilitate maintenance and management.

Wall-mounted wiring equipment installed on the ② walls should not be less than 30Omm from the ground height. If there is a movable floor between the equipment, it should be guaranteed that no less than 300mm is the height of the bottom of the wiring equipment from the active floor to 30Omm.

7 The equipment should be equipped with not less than two 200V belt protection grounding single-phase power sockets, but not as equipment power supply. Equipment such as the installation of telecommunications equipment or other information network equipment, equipment power supply should meet the corresponding design requirements. The contents of this article are equally applicable to telecommunications.

into the line room

In the intelligent building, it is advisable to set up 1 lines, its position is generally located in the underground layer, the external communication (information) network to introduce cables and pipelines from two different directions or routes into the line, which facilitates the two pipelines and the external pipeline network communication. Human holes or hand holes (i.e., manhole or hand holes in the courtyard of intelligent buildings) between the lines and the outer red line of the building may be interconnected by means of pipelines or channels.

There are many factors involved in the line, the national standard "integrated wiring system Engineering Design Code" (GB50311 12,007) only put forward the principle requirements, the reader can be based on the intelligent construction of the actual project, according to the communications industry standards and other relevant standards for the design, the specific principles are as follows.

1 Enter the line should be set up underground communication (information) pipeline entrance site.

2 The line should meet the cable routing, Chengduan location and layout and number of cables, Yuliupan long space and cable bending radius, inflatable maintenance equipment and wiring equipment required for the installation of space and plane area and the operating activities of the empty L.

3 the size and shape of the incoming line shall be designed according to the final capacity of the inlet pipe and the final capacity of the entrance facility. At the same time, consideration should be given to the number of telecommunications operators to install the installation of cable and import facilities and other equipment area.

4 The line should be close to the outer wall of the building and be set in the ground to facilitate the introduction of the underground cable. The following provisions shall generally be complied with in the entry-line setting.

① to prevent seepage between the line, it is advisable to set drainage equipment, so as to avoid long-term accumulation of water.

The ② should be communicated with the cable shaft close to the integrated wiring system to facilitate the vertical introduction of the trunk cable and facilitate the currency and layered supply line.

③ should be used in the corresponding fire level fire door, door open, width should not be less than 1000mm.

The ④ should take measures to prevent harmful gas from entering, and set up the ventilation device, and the exhaust air volume is not less than per hour, and the secondary volume is calculated.

⑤ other public pipelines unrelated to the incoming line are not suitable for adoption or laying.

5) into the line between the introduction of all the pipe end of the cloth cable and free pipe holes, should be taken waterproof material plugging, the same limb to do water treatment.

6) in-line, such as an assembly line equipment and communications (information) facilities, should meet the requirements of equipment installation design.
