Management between integrated wiring equipment and cabling

Inter-device management of Integrated Wiring

The device room is the installation location of telephone switches, computer network equipment, and building wiring equipment BD in intelligent buildings. It is also a place for network management. For the Integrated Wiring System Engineering Design, the general wiring equipment is mainly installed between devices. When the communication information) facilities and wiring equipment are set separately, the length constraints of the equipment cables should be taken into account, to reduce the length of cables and improve the transmission quality, try to shorten the distance between the devices that install the total distribution frame and the devices that install the user telephone switch and the Computer Host.

If one device is calculated as 10m2, about 5 standard rack cabinets can be installed ). In the cabinet, you can install a large number of pairs of telephone cables, a multi-to-card module, and a data trunk cable distribution device module. This module supports a total of 6000 information points, of which 50% are telephone and data information points respectively) the installation space of the building wiring equipment.

National Standard GB50311 a 2007 on the installation process requirements between equipment have the following provisions.

1) the location of the device room should be determined based on factors such as the quantity, size, and network composition of each installation and setup.

2) set at least one device in each smart building. If the telephone switch and computer network equipment are installed in different places or according to network security requirements, you can also set two or more devices to meet device installation requirements for different services.

3) the design of the equipment room involves a wide range of areas. To this end, the following regulations and relevant professional requirements should be met.

① The equipment should be located in the middle of the trunk subsystem, and the transmission distance and number of trunk cables should be reduced to save investment in engineering construction.

② The location of the equipment room should be as close as possible to the cable shaft in the building or near it, which is conducive to the introduction or access of the trunk cable, facilitating the construction and maintenance.

③ The location between devices should facilitate device grounding.

④ The equipment room should be kept away from high and low voltage transformer power distribution, motor, X-ray, radio transmission and other sites with electromagnetic interference sources, and must meet or exceed the minimum clearance between them, to reduce the impact of electromagnetic interference on communication information.

⑤ The indoor temperature in the device room should be 10℃ ~ 35 ℃; relative humidity: 20% ~ 80%, and should have good ventilation conditions.

⑥ There should be sufficient device installation space between devices, and The use area should not be less than 10mz. This area does not include the installation equipment required by the user's program-controlled telephone switch, computer network equipment, and other facilities.

7. Avoid having structural components such as columns in the equipment room. If there is a housing beam, the net height of the beam should not be less than 2.5 m. The door should be no less than 1.5 m in width.

4) the equipment room should prevent the invasion of harmful gases such as chlorine, carbohydrate, hydrogen sulfide, nitrogen oxides, carbon dioxide, etc., and should have good dust-proof measures, the dust content limit shall comply with table 2.36. The dust particles in the table shall be non-conducting, non-Iron magnetic, and non-corrosive.

5) within the seismic area, equipment installation shall be carried out in accordance with the provisions of the seismic design specifications for communication equipment.

(6) communication information) the installation of a device between devices shall comply with the following requirements.

① Rack Cabinet) the front clearance should not be less than 800mm, and the rear clearance should not be less than 600mm to facilitate maintenance and management.

② The height of the wall-mounted wiring equipment installed on the wall from the ground should not be less than 30Omm. If an active floor is installed in the device room, ensure that the height from the bottom of the wiring device to the active floor is no less than 300mm.

7) no less than two single-phase power outlets with protection grounding shall be provided between the devices, but shall not be used as the power supply for the equipment. If telecommunications equipment or other information network equipment is installed between devices, the power supply of the equipment shall comply with the corresponding design requirements. The content of this article also applies to telecommunications.

Management of Integrated Wiring cabling

In an intelligent building, one cabling room should be set up, which is usually located on the ground floor and external communication information.) The cables and pipelines introduced by the network should be introduced into the cabling room from two different directions or routes, this facilitates communication between two pipelines and external pipeline networks. The manhole or hand hole in the courtyard where the intelligent building is located can be connected by pipeline or channel.

There are many factors involved in the cabling. GB50311-2007, the national standard for the engineering design of integrated wiring systems, sets only the principle requirements. Readers can follow the actual engineering conditions of Intelligent Buildings, the specific principles are as follows.

1) underground communication information should be set up between the incoming lines.) The entrance part of the pipeline.

2) the cabling routes, end location and layout and quantity, the remaining disk space and bending radius of cables, and the space required for installation of inflatable maintenance equipment and wiring equipment should be met. and the plane area and the empty l of the operation activity.

3) the size and shape of the incoming line should be designed based on the final Capacity of the incoming line and the final Capacity of the entrance facilities. At the same time, it should be considered to meet the needs of multiple telecom business operators to install and introduce cables, Portal facilities, and other equipment.

4) The cabling room should be close to the outermost exterior wall of the building and set in the ground to facilitate the introduction of underground cables. The entry period setting should generally comply with the following requirements.

① Water seepage should be prevented between the cables, and drainage equipment should be set up to avoid long-term water accumulation.

② The cabling room should communicate with the cable shaft close to the cabling system to facilitate vertical leading of the trunk cable and facilitate coin placement and stratified supply line.

③ Fire doors of the fire prevention level should be used between the incoming cables. The door should open outward and the width should be no less than 1000mm.

④ Measures should be taken to prevent harmful gases from entering the air intake line, and a ventilation device should be set up. The exhaust air volume should not be less than per hour. The next volume is calculated.

⑤ Other public pipelines irrelevant to the incoming question should not pass or be laid.

5) All cables and idle pipe holes at the end of the pipeline should be inserted into the inlet room. waterproof materials should be used to block the cables, and the same limbs should be waterproof.

6) The installation and design requirements should be met for the installation and communication facilities within the cabling room, such as assembly line equipment and communication information.

The management of the cabling room and the device room is introduced here. I hope you can understand it.
