The requirements of the communication machine room for the environment
足彩对阵表1. Air environment management and maintenance
The management and maintenance of the machine room mainly include electric environment, temperature and humidity, dustproof, fire prevention and anti-rat.
(1) electrical environmental requirements
足彩对阵表The requirement of electrical environment mainly refers to anti-static demand and anti-electromagnetic interference. Antistatic requires a large number of semiconductor MOS, CMOS, etc. Because this kind of device is sensitive to electrostatic range of 25 ~ 1000 v, and the static electricity generated by the electrostatic voltage is often as high as several kilovolts even tens of thousands of volts, enough to breakdown of various types of semiconductor devices, so the room should be laid anti-static raised floor, the floor bracket to ground, wall also should do anti-static processing, machine room cannot be laid in chemical fiber carpets. Workers should wear anti-static clothing and anti-static shoes in the machine room and avoid entering the machine room in chemical fiber clothes. Cupboard door should be closed, usually move equipment and personnel in the telecom room take the spare parts when the movement wants light, and as far as possible to lower the number of walks back and forth in the room, so as to avoid the object movement between static friction.
It is necessary to clean the equipment once and for the long run but not always clean. In the long term maintenance work, the circuit board is sometimes called the alarm. If the circuit board is replugged, the circuit board will return to normal.
足彩对阵表(2) temperature and humidity requirements
Telecommunication equipment, especially the switch and other equipment, have higher requirements on the temperature of the machine room. The temperature is high, the machine can be easily cooled, the work parameters of the transistor drift, the stability and reliability of the circuit can be affected, and the breakdown of the components can be caused when serious. Communication equipment during the work in the long run, the machine temperature control between 18 ℃ to 25 ℃ is more appropriate. Do not install heat in the communication machine room and avoid the heating pipe from the machine room. Humidity has great influence on communication equipment. The air is wet, the metal parts of the equipment and the fittings of the equipment are caused by rust, and the insulation of the circuit board, plug and wiring is reduced, and the circuit can be short-circuited seriously. The air is too dry and prone to electrostatic effect, threatening the safety of communication equipment. Generally speaking, the relative humidity in the machine room stays within 40% ~ 60% range.
(3) dust control requirements
If the components of electronic devices, metal connectors and other components can cause insulation and poor contact, the circuit will be short-circuited seriously. There is a large amount of suspended matter in the air. In these suspended matter, there are numerous pollutants that are harmful to communication equipment. Once the pollutants enter the machine room, they will be attached to the circuit board, forming charged dust that the human eye can detect and cannot detect. As time goes by, the dust on the circuit board absorbs more and more dust, and the dust will affect the normal operation of the equipment in different ways.
足彩对阵表If the maintenance personnel are not solved in time, the maintenance of the equipment is actually passive maintenance.
The communication machine room should have 7 by 24 hours of professional security personnel, when the user enters the machine room, need to register or hold a pass card to enter inside. In order to ensure the safety of the user's custody equipment, the communication machine room must have the TV monitoring and access control system, and the whole floor has no requirement to monitor the blind area. The TV wall monitoring system should be kept for 7 by 24 hours, and all videos shall be kept for 3 months. In and out of the room entrance guard system must adopt advanced database management, insourcing entities cardholder user identity card no., in and out of the area restrictions and time limits, etc., only specially authorized personnel can enter into important areas.
足彩对阵表3. Fire protection
足彩对阵表The communication engine room should adopt fire protection frame and material, fire fighting capability should meet the telecommunications level standard, and have multiple emergency channels. Temperature smoke sensor and fire alarm detection head should be installed in the machine room and the building road. The system will automatically alarm the fire when it is in flames, and the inert gas extinguishing system will be activated. In addition, the machine room can also be equipped with a portable, stroller fire extinguisher.
足彩对阵表4. Supporting power supply
As the power equipment of intelligent and highly integrated, in integration scheme design, a variety of power equipment should have good electromagnetic compatibility and electrical isolation performance, does not affect the normal work of the other devices. The integrated power supply scheme shall ensure the good compatibility and universality of the data communication between the power equipment while ensuring the uninterrupted power supply of the main equipment. Various data protocol compatible well to form a complete dynamic monitoring network system, effectively implement interactive associated control, this is for a test can provide more products and services vendors.
The current situation of the communication machine room
Due to the relationship between engineering design, construction investment and human resources, some problems exist in some communication machine rooms.
First, the computer room environment does not conform to or reach the requirement of the telecom room, there may exist at the early stage of the construction site selection inappropriate, communication machine room after room environment change no positive adjustment factors, caused some hidden dangers to the safety of the telecom room.
Secondly, it does not attach importance to relevant supporting facilities. Most of the supporting facilities are completed in the early stages of the construction of the communication machine room. For this part of the facility, our attention is often inadequate, and it is easy to show that the supporting facilities cannot keep up with the expansion or overload of communication construction.
Third, the maintenance personnel skills are insufficient, the training is not enough, the actual operation is not skilled enough.
Fourthly, a considerable part of the equipment emergency plan has insufficient execution.
Fifthly, considering the cost of investment, the area of machine room after completion of the construction is very difficult to change, it requires to limited room space when the design maximum economic benefits, this is also our lacking right now.
