Important conditions for computer room construction
The decoration of the computer room:
First, design and plan in accordance with relevant standards and technical specifications, according to the specific selection of equipment and installation requirements, and secondly, try to meet the conditions of lighting, dust and sound insulation, and create a reasonable working environment. Among them, we should consider: ceiling And wall decoration materials and structures should meet the fire protection requirements. The power cord buckle uses flame-retardant decoration materials, and the surface is treated with flame-retardant coating to meet the requirements of flame-retardant and arson. The floor of the computer room preferentially use the anti-static floor with abrasion-resistant and anti-static veneer, which has good anti-static performance and has no deformation or fading after long-term use; the floor clearance height is usually 10-50cm. The room should consider the configuration of lighting fixtures, air-conditioning and humidity equipment: The Anhui website is designed to be soundproof and dust-proof, and it needs to be equipped with double-layer alloy glass windows, with blackout curtains and so on.
The height and space of the computer room:
The height and space of the computer room should be considered after laying the floor and the net height of the suspended ceiling. Since the machine room mostly adopts the way of lower cable entry, wiring ducts and ventilation should be laid under the floor, and the floor height is generally about 10-50cm; and the ceiling of the roof should generally be taken from the lower part of the lintel, and leave enough lamps and fire-fighting equipment to be buried in the dark The height usually occupies a certain height, so that the net height of the room has been reduced by nearly 1m. The height of an ordinary building will appear lower after the equipment room is renovated, which is also not conducive to the installation of equipment. The net height of the house should be in the range of 3.2m～3.3m (the machine room is equipped with a cable rack or channel). At present, air supply ducts should be provided under the floor of the large-scale computer room of Anhui web design. Therefore, the computer room building or specific floors and computer rooms should be designed as a whole during the design of construction facilities. For the central computer room, with the development of new technologies and equipment, the business will continue to expand, and some equipment space should be appropriately reserved according to the trend of medium and long-term development. Equipment room construction equipment is generally installed according to the principle of isolation between cabinets and operation rooms, especially switches, optical transmission equipment, cluster equipment and other high degree of automation. The network management system can complete most of the equipment commissioning, monitoring and system operations without frequent entry into the cabinet room. , This can reduce the impact of human factors on the equipment.
Crossing of signal cable and power supply cable:
Should follow the relevant regulations, pay attention to the civil engineering reservations to follow the parallel cable separation distance not less than 50 ~ 60cm, pay special attention to when the shaft passes through the floor, try to keep the distance as much as possible to avoid the power line interference communication transmission. In the computer room, station area communication, power line dense manhole, and cable room, more attention should be paid to the optimal layout of their respective coils and paths. Fire protection in the engine room:
It is necessary to consider the fire fighting design of the computer room. The interior decoration design determines the design plan of the computer room according to the fire protection level setting. The building first requires conventional fire hydrants, fire channels, etc., and installs smoke and temperature detection devices according to the area of the computer room and equipment distribution. Automatic alarm bells and indicator lights, automatic/manual fire extinguishing equipment and equipment. The fire alarm in the computer room requires a duty room or monitoring point on the first floor. requires attention:
The country has issued corresponding specifications and requirements for the fire protection design of the computer room. After the plan is formulated, it should be proactively reported to the fire department for approval. At the same time, attention should be paid to the coordination and adaptation of the decoration of the computer room and the fire protection. .
Lightning protection for computer room buildings:
Since the communication and power supply cables of the computer room are mostly introduced into the computer room from outside, they are vulnerable to lightning attack. The lightning protection design of the computer room is particularly important. This is often overlooked in the usual station building design. The lightning protection of the computer room should be effectively removed. In addition to protecting the safety of the building itself, it should also lay a good foundation for the lightning protection and working grounding of the equipment. The joint grounding method is often used in electromechanical engineering, and the grounding of the system equipment is connected with the building grounding. After the building's lightning protection design and construction are completed, an accurate system grounding grid or grounding ring belt location and layout diagram should be provided to avoid conflicts between the equipment grounding grid and the building grounding grid. Due to the special requirements of joint grounding, it is forbidden to directly use building grounding wires and power grounding wires as the ground wires of system equipment in electromechanical engineering.
Under the condition of meeting the design site selection and design height, if the building design of the computer room can be used to build the iron tower on the top of the building in the civil design, it is an economical solution, and there are many successful experiences in various places.
