Computer room security automation monitoring system

（1）Noise reduction and insulation of the venue
（1） According to the "Design Specification for Electronic Computer Room", the noise in the main computer room should be less than or equal to the measured value at the position of the main operator under the condition of computer system shutdown68dB（A）. And it is stipulated that the host room should be kept away from noise sources. When unavoidable, soundproofing and sound insulation measures should be taken.
Noise is a type of sound that people do not need, which can cause irritability and poverty, distract attention, and reduce work efficiency. Whenever conditions permit, measures should be taken as much as possible to reduce the noise level of the environment.
The specific noise reduction measures to be considered are as follows:
1）The insulation layer installed on the floor can absorb sound3dbThe raised floor can provide sound insulation20db.
2）The entire computer room area is equipped with facilities between each computer room40dbA wall or glass partition with noise isolation capability“Hard board”——Sound damping; XPS——Sound absorption, glass partition, sound insulation15dbIt can effectively avoid noise crosstalk between different regions.
（2） The "Code for Design of Electronic Computer Room" stipulates that the construction and materials of the enclosure structure of the electronic computer room should meet the requirements of insulation, heat insulation, fire prevention, etc. This is particularly important for precision air conditioning areas, where the temperature is controlled during summer23 ±2℃Winter temperature20±2℃Due to the large temperature difference with the outside world, corresponding insulation measures should be taken from the perspective of energy conservation.
In the precision air conditioning area, rubber insulation layer and galvanized steel plate are laid along the floor, and the light steel keel partitions and veneer walls in each room are filled with insulation cotton to provide sound and heat insulation.

（2）Site purification
The cleanliness standard for precision air conditioning areas specified in the "Design Specification for Electronic Computer Room" is:AGrade, air dust concentration, tested under specified conditions, greater than or equal to per liter of air0.5μmThe number of dust particles should be less than18,000Grain.
The use of precision air conditioning in the computer room area requires specific consideration of purification requirements, while other levels of rooms may not be considered. To meet the national standard requirements, the following technical requirements should be met:
1． The main source of dust is fresh air introduced from the outside, and the dust filtration efficiency of the fresh air should be controlled within70%above;
2． The dust filtration efficiency of precision air conditioning units should be controlled within95%above;
3． A positive pressure fresh air system is installed in the computer room area, with indoor air pressure higher than outdoor air pressure9.8paCan effectively repel dust outside the indoor area;
4． Precision air conditioning circulating air supply volume300m3/H/(KWLing Liang)The commonly used air conditioning unit has a circulating air volume that can filter indoor air every hour30Under specific conditions of atmospheric dust content in the city, the number of air conditioning airflow cycles is20order/HAt this time, the dust content in the computer room can be controlled to be better thanALevel of proficiency;
5Typically, computer rooms use typical“last/distributed”The air conditioning airflow organization scheme involves the main air flow being transported through the underfloor supply air static pressure box. The supply air flows through the floor supply air outlet into the venue, and the airflow inside the venue flows from bottom to top. Dust on the venue enters the return air static pressure box inside the ceiling with the airflow. Furthermore, dust filtration is required when the air conditioner is returned to the air conditioner through negative pressure suction at the return air outlet. Therefore, the amount of dust in the site has greatly decreased;
6Delivery in the computer room/Inside the return air static pressure box, purification process is carried out, and the walls are decorated with smooth and dust-free materials.
（3）Waterproofing of the venue
For computer rooms, excessive humidity or the generation of moisture can pose serious hazards to computers and their external equipment, magnetic media, paper media, cables, etc. From a building perspective, it can also be detrimental to the enclosure structure. According to the Design Specification for Electronic Computer Room,AThe relative humidity of a computer room with a standard level should be controlled within45%~65%.
For this project, specific waterproof requirements need to be considered from the following aspects
（1） Prevent condensation of fresh air flow due to temperature differences
If the fresh air in the computer room area is directly introduced from the outdoor atmosphere, during high temperature seasons and high humidity, the introduced fresh air will mix with the air inside the computer room23℃+-2℃When air flows in, a small amount of condensed water will be generated. The fresh air unit is installed at the upper end of the precision air conditioner, and the introduced fresh air directly enters the interior of the air conditioner. The condensed water generated can be collected into the air conditioner and discharged directly through the drainage pipe of the air conditioner.
（2） To prevent water leakage in the event of an air conditioner accident
In the environmental monitoring system, a leakage sensing automatic monitoring system is installed on the ground of the air conditioning area, which can monitor the leakage status of the ground in real time.
（3） To prevent water leakage from adjacent water sprinkler fire extinguishing areas, fire sprinkler humidification water pipe systems, and other water sources from entering the computer room area, install high height along the perimeter wall of the computer room700mmWaterproof ridge walls prevent external water from flowing into the computer room.
（4） Prevent water seepage from the exterior walls of the venue
After waterproofing treatment is applied to the exterior and interior walls of the site enclosure, the interior wall protection layer structure is installed.
（4）Fireproof treatment
Except for non combustible or flame-retardant materials, flame-retardant materials should be selected as much as possible for other materials. All concealed wooden parts should be painted with fireproof paint for fire prevention treatment. The evacuation exit is marked with prominent emergency exit signs to facilitate personnel evacuation.
（5）Site rodent prevention
To prevent mice from damaging the cables，All pipeline slots connecting the computer room to the outside world are sealed with specialized fireproof mud, and the enclosures of each fire zone are appropriately isolated and sealed above and below; All openings under the cabinet are addedPVCSheath; Each professional pipeline is placed in its own metal bridge or covered with metal pipes.
