Several Problems to be Considered in the Construction of Weak Current Machine Room

Weak current machine room constructionIt refers to providing a reasonable, efficient and convenient investment environment through the four basic elements of structure, system, service, management and their interrelationships to help enterprises achieve cost, convenience and safety goals.

computer room constructionThere are many precautions from design to construction, and I believe many people know little about the specific details.

1.Room layout.
Mainly include: location, area, scalability, sealing, etc.
In general, the design of the room should consider the future scalability, rather than the mountain and dark location. The area should be more than twice the space used by all equipment, and sufficient personnel management and maintenance space should be reserved. The computer room is a closed space, the conditions allow as far as possible to do the peripheral visible, generally use transparent or translucent glass, you can directly observe the internal situation of the computer room from the outside.

2. power supply system.
1. The amount of electricity introduced should reach the expected total capacity. If conditions permit, it should be as redundant as possible.
2. The power cable must use the whole section of wire, no joint in the middle, the outer skin must not be damaged, and the cable with reliable quality should be selected.
3, must be grounded to prevent leakage.
4. The computer room should be equipped with UPS uninterruptible power supply, the load should not exceed 80%, the duration should be at least 60 library minutes, and should be equipped with input and output voltage, current and other display devices.

3.weak current system.
The whole adopts Gigabit Ethernet, and the line adopts category 6 twisted pair.
Construction requirements: the total length of the single line is not more than 90 meters, there is no breakpoint in the middle, no dead knot, and the wiring process cannot be stretched strongly to ensure that the skin is in good condition. The 8-core wire in the network cable is a qualified standard. Each line must have the same and unique line mark at both ends, and line drawings shall be provided at the end of construction. Conditions allow the use of wire racks as much as possible to facilitate later management and maintenance.

4.Computer Room Environment.
1. In order to improve the air cleanliness inside the computer room, the surfaces of the walls, floors and ceilings should be flat and not easy to accumulate dust. The wall surface shall be decorated with fireproof, moisture-proof, dust-free and easy-to-clean materials, and the floor and ceiling shall be waterproof.
2. The floor material is hard and there should be no dust. Anti-static materials, if conditions permit, try to install anti-static raised floor. The overhead height of the floor is 20-750px, and strong and weak current trunking is laid under it.
3, anti-electromagnetic interference, lightning protection.

5. air conditioning system.
The temperature in the machine room is kept at a constant temperature of 22 ℃ ± 5 and the relative humidity is 50%± 10. As far as possible to install the room dedicated air conditioning (also known as precision air conditioning). Compared with ordinary household air conditioners (also known as comfort air conditioners), the design difference is large. Precision air conditioners pay more attention to eliminating heat and have humidity adjustment functions. General air supply, air recovery, stability and service life are higher than ordinary household air conditioners, which are more suitable The machine room runs all year round.

6. fire safety.
The machine room should be equipped with electronic equipment fire fighting device, try to install automatic alarm and fire fighting device.
