The monitoring command center has two main functions for laying the raised floor. First, a concealed space is formed under the raised floor, and source lines, trunking, integrated wiring, fire lines, etc., as well as some electrical facilities (sockets, socket boxes, etc.) can be laid under the floor. Secondly, the movable floor can be placed at the event. An air conditioning air supply static pressure box is formed under the floor. In addition, the antistatic function of the raised floor also guarantees the safe operation of computers and network equipment. There are many types of raised floors. According to the substrate and material, it can be divided into: aluminum alloy, all steel, composite wood particle board and so on. The surface of the floor is pasted with anti-static veneer monitoring and command center. The raised floor is made of imported 600mmX600mm all-steel anti-static floor, floor tiles and carpet.
2. The height of the floor of the monitoring command center is 0.2-0.3 meters. During the installation of the raised floor, the floor and the wall are at the junction, and the raised floor needs to be cut accurately. The cutting edge needs to be sealed after installation. After the floor is installed, it is decorated with stainless steel skirting boards. The stainless steel skirting board and the stainless steel glass partition wall set off each other, and the effect is good. In order to meet the design of the air supply under the air conditioning system, the raised floor has a dedicated ventilation floor. The ventilated floor is individually machined, aluminum construction. In order to match the wiring of strong and weak current systems, the raised floor has a dedicated floor with a wire strip, which is equipped with a plastic outlet and is routed inside the line. When installing an anti-static floor, install an electrostatic leakage system on the ground and lay an electrostatic leaking ground net. Seal the static leakage line and the ground terminal of the monitoring and control center safety ground to leak static electricity.
(3), wall surface
The wall of the monitoring command center is a reinforced concrete wall (partial glass curtain wall). Both the glass curtain wall and the outer window should be sealed and double-layered metal closed windows. Beautify the original wall, install color steel plates, decorate wall panels, etc.

A complete computer room power supply and distribution system is the basic condition for ensuring reliable operation of site equipment and auxiliary power equipment. Establish a high quality, highly safe and reliable power supply and distribution system. A high-quality monitoring and command center power supply system is reflected in no single point of failure, high fault tolerance; online maintenance without affecting load operation; lightning, fire, water, and grid surge protection.
1, computer power distribution requirements
1) Monitoring command center power supply
Frequency: 50Hz
Voltage: 380V/220V
Phase number: three-phase five-wire system and single-phase three-wire system
2) Monitoring command center power supply level
According to the performance, use and operation mode (whether networked) of the equipment, the power supply quality grade is divided into three levels (A, B, C), and the quality of the power supply of the monitoring command center project must meet the A-level standard.
4) The monitoring and command center uses electrical equipment and distribution lines to install two-stage over-current overload protection. At the same time, the power distribution system is selectively matched with each other, and the power distribution is radiated to the power equipment.
5) The monitoring command center distribution system is linked with the fire protection system.
2, power supply
(1) The monitoring and command center is designed as a primary load according to national regulations. The primary load requires that the power supply and distribution system has very high reliability. Therefore, the total power supply of the primary load should meet the following requirements:
(2) The primary load is supplied by two power sources. When one power supply fails, the other power supply should not be damaged. The two power supplies are mutually standby, and each power supply can bear the full load of the project. That is, when a normal working power failure occurs, another backup power source can be automatically put in through the ATS. When the mains power is cut off, the UPS system supplies power to ensure the continuity of the power supply of the network and computer equipment in the monitoring command center.
(3) The monitoring and command center project adopts TN-S low voltage 380V/220V three-phase five-wire power supply mode. Party A is responsible for providing two-way 300KVA “two-way mains power” to the power cabinet AP1 to ensure that the other mains power is automatically cut in the event of a mains failure.
3. Power supply and distribution system - power supply mode
(1) The power supply and distribution system is divided into three parts: the first part is the power supply for the UPS equipment, and the second part is the precision air conditioning power system. The third part of the lighting system is powered. The power distribution design of the computer equipment and monitoring equipment in the monitoring command center area is the power supply mode of “two-way mains + UPS uninterruptible power supply”. The precision air conditioning power distribution of the monitoring and command center is designed as a “two-way mains” power supply. The monitoring and distribution center lighting distribution system is designed as a "two-way mains" power supply mode, and the emergency lighting power supply is taken from the UPS uninterruptible power supply. The UPS should use an array of 120KVA and a 60-minute battery to ensure that the uninterrupted power supply time is no less than 2 hours.
(2), using electric power accounting:
The monitoring command center UPS only considers the main monitoring command center area and emergency lighting power. Monitoring and control center equipment power: monitoring command center lighting system: monitoring command center area is 200 square meters, calculated according to electricity power 20W / square meter, a total of 4KW. Total power consumption: KW. The power factor is 0.8, resulting in a total power load of 159.84 KVA.
(3), lighting system
1), design standards and basis:
The requirements of the computer monitoring and command center for lighting: monitoring and command center lighting according to the "electronic computer room design specification" GB 50174-93, Chapter 6, Section 2, meet the requirements for illumination, illumination uniformity (not less than 0.7), Lighting stability and glare suppression requirements.
2), lighting design: monitoring command center area: illumination 250lx ~ 350lx. Lamp selection and arrangement: According to the illumination of 350lx, the 3*40W embedded grid fluorescent lamp is arranged in the monitoring command center. Emergency lighting, evacuation lighting and safety exit sign lights: Emergency lighting is considered at 1/10 of general lighting. The emergency light and safety exit sign light shall not be less than 0.5lX. Emergency lighting and exit indicators are powered by the UPS.
3), lighting control mode: the lighting uses the principle of partitioned dispersion control to facilitate energy conservation. The emergency lighting is separately threaded and individually controlled by the wall fluorescent display slab switch. The main lighting is controlled by the control box, and the partial use of the slab-type dark switch is installed on the wall at a distance of 1.4m from the ground.
(4) Electrical installation: The distribution cabinet is installed on the floor, and the angle of the angle bracket is the same as the height of the floor. The distribution box is 1.4M away from the ground, and the wall socket is 0.3M away from the ground. Industrial connectors are used for large equipment, and terminal blocks are used for cabinets. UPS power outlets and mains outlets are available in different colors or markings.
(5) Cable selection and laying method: The current carrying capacity of the wiring cable in the decoration of the monitoring command center is affected by the ambient temperature and the cable laying in bundles. The ambient temperature is +30 degrees. Each electrical load distribution line and cable are laid under the floor or in the ceiling, all of which are laid through metal pipes or in metal trunks, and the ends of the cables are made of metal hoses. Flame-retardant cross-linked cables are used for all cables. All metal trunking and wire tubes are reliably grounded.
(6) Equipment grounding system: According to the relevant items in the fourth section of Chapter 6 of GB 50174-93 of the Electronic Computer Room Design Specification, the grounding of the monitoring command center has the following requirements: the type and purpose of the grounding type are usually used to ensure the monitoring of the command center. The safety of various equipment requires that the monitoring and command center monitoring and command center has four types of grounding, namely: computer-specific DC ground, power distribution system communication work ground, safety protection ground, and lightning protection ground.
1), computer-specific work place: used to protect computers, servers, network equipment, etc., define the working voltage of the computer system, the reference ground value of the output signal, usually in the computer system, there are two possibilities: First, there is a separate DC working place , the DC working ground is placed in absolute zero; Second, there is no separate DC working ground. No matter which way the computer system works, the judgment of the high and low levels of the output signal is the same as the principle of the high and low level of the DC power system. Both high and low levels are required to be stable and undisturbed.
2), distribution system AC work site refers to the working place of the power system, according to the various forms of grounding in the "Electrical Design Code for Civil Buildings" to ground the neutral line (N) in the entire system.
3) Equipment safety protection grounding refers to grounding the non-charged metal parts of high and low voltage electrical equipment. The non-charged metal part includes: a metal conduit, a metal trunking, a metal armor of a cable, an outlet raft, a metal outer casing such as a motor frame, and a metal outer casing of various electrical equipment.
4) Lightning protection and grounding, establish a joint common grounding body, form an equipotential lightning protection system, and build the foundation reinforcement of the building (including pile foundation, cap, floor, ground beam, etc.), beam and column reinforcement, metal frame, construction The lightning protection down conductors are connected to form a well-closed Faraday cage grounding, and the grounding of all parts of the building (including AC work ground, safety protection ground, DC working ground, lightning protection grounding) and the building Faraday cage are good. Connect to avoid potential differences between the ground lines to eliminate induced overvoltage. The national standard "Code for lightning protection design of buildings" GB50057-94 (partial amendments) clearly stipulates that equipotential connections must be made at the junction of lightning protection areas; especially the weak monitoring and control center of the calculation and control command center in the building, suffers The possibility of direct lightning strike is relatively small, so in addition to the use of surge protectors for inductive lightning protection, equipotential bonding should also be used for lightning protection.
5), specific practices:
Grounding, fire, monitoring and lightning protection of building electrical equipment share the grounding grid of the original building. From the joint grounding body of the building, lead a VVP1×50 grounding wire (provided by Party A) to the grounding terminal box of the power distribution room of the monitoring command center for use by the UPS equipment. Lightning protection, PE, weak electricity share the grounding grid, the grounding resistance is not more than 1 ohm (provided by Party A). Equipotential bonding is formed in each computing monitoring command center area. The 30×3 braided copper strip is laid under the raised floor. According to the layout of the computer equipment, the grid is formed vertically and horizontally with an interval of 1.8×1.8 meters to form an equipotential grounding grid.
(3) Lightning protection system
The main ways of lightning damage to electronic equipment are direct lightning strike, lightning strike, induced lightning, ground potential counterattack caused by lightning current, transient electromagnetic field caused by lightning current and lightning flash electromagnetic pulse. The lightning protection of the monitoring command center area is mainly to prevent inductive lightning (the direct lightning is prevented from being designed by the building), and the electromagnetic pulse generated thereby generates or induces an overvoltage caused by overvoltage and overcurrent, resulting in a counterattack, resulting in a potential difference.
The lightning protection design mainly adopts three levels of lightning protection measures for the power supply and distribution system of each monitoring and command center. The main distribution room of the first-level building is used for lightning protection measures, and the second level is equipped with lightning protection devices for the power distribution cabinet. Install the lightning arrester in the UPS output power distribution cabinet.
1. Anti-induction lightning strike:
When thundering, the lightning wave is easily inducted from the antenna feeder, signal line, and power line to damage the device. Therefore, the antenna feeder arrester, signal lightning arrester, and power surge arrester with the same parameters related to the protected device must be installed in the corresponding parts. It is now described as follows:
2. Power supply arrester:
The statistical probability indicates that when lightning strikes, the probability that the lightning wave will invade the equipment from the power line is as high as 70~80%. Therefore, it is necessary to guard against the power system. Generally, multi-level protection is required, and two levels are often used. To the fourth level. The power supply arrester is connected to the power line, usually in a high-impedance state. Its starting voltage is higher than the power supply voltage. Once the lightning wave is sensed from the power line and exceeds the starting voltage of the arrester, it will be in 10-9 seconds. When the nanosecond is turned on, the lightning wave is introduced into the ground, and the device is not broken into the device to destroy the device. After the thunder, the high-resistance state is quickly restored. Because the response time of the arrester is extremely fast, it does not affect. The device is powered normally and protects the device from lightning strikes.
(four), static protection
1. Use anti-static special floor to discharge static electricity on the floor and wall side in time, and make several sets of anti-static grounding in the floor area. Avoid static electricity damage to computer equipment and random failure caused by static electricity and protect personal safety. Monitor the workbench and cabinets in the command center area and easily accumulate static charges in a large area. Use static conductive materials and ground the static electricity.
2. Anti-static grounding. In the monitoring and command center, all metal floors and metal wall panels need to be reliably grounded. The supporting feet of the raised floor must be connected by the grounding wire and integrated into the common ground end with a dedicated line.
(5), precision air conditioning system
1. Design goals
The monitoring and command center environment plays a vital role in the normal operation of the equipment in the monitoring and command center. Maintaining the temperature, humidity and cleanliness in the monitoring and command center is a necessary condition for ensuring the normal operation of the monitoring and command center equipment.
2. Monitoring the command center's requirements for cleanliness
The environment of the monitoring and command center is realized by the air conditioner. The monitoring command center should be sealed and the wall enclosure structure should be clean. The monitoring command center should maintain a positive pressure to prevent dirty air erosion. The air conditioner is equipped with a medium efficiency filter and is regularly replaced to ensure that the air in the monitoring command center is purified in continuous circulation.
3, system design instructions
(1), monitoring and control center environmental characteristics
The computer and network equipment in the monitoring command center have large heat dissipation and concentration during operation, and the amount of moisture dissipation is extremely small. 95% of the heat dissipation is sensible heat, the heat-humidity ratio is extremely large, and the enthalpy difference is small. In this case, air treatment can be approximated as an isothermal cooling process.
According to the way of heat propagation - conduction, radiation, convection analysis, the most effective way to evacuate sensible heat is convection, which requires a lot of cold wind to carry away heat.
In addition to temperature requirements, computer equipment also requires humidity. The centralized air conditioner can not control the constant humidity. If a humidity control system is added, the investment and maintenance amount will be increased invisibly. The special air conditioner realizes the automatic control of the humidity, so that the computer equipment can work normally under constant humidity in the extremely humid summer or in the extremely dry winter.
In addition, the monitoring and command center has strict requirements on cleanliness, which is much higher than office space. Due to the characteristics of the air supply mode of the centralized air conditioner, it cannot meet this requirement. The special air conditioner has a medium-efficiency filter system, which can be replaced at any time, which is convenient, time-saving and economical.
At the same time, according to the characteristics of the enclosure structure of the monitoring command center (mainly wall, top surface, ground, including: floor, orientation, exterior wall, interior wall and wall material, and door and window type, single and double layer structure and gap, heat dissipation ), the heat generated by the personnel, the heat generated by the lighting fixtures, the fresh air load, and other factors, calculate the cooling capacity required to calculate the monitoring command center, and therefore the capacity of the air conditioner is selected.
(2), air conditioning selection
1), systematic review
Centralized air conditioning mainly considers the human body's environmental requirements and does not have a large amount of air. Therefore, the centralized air conditioning method will have the problem that although the amount of cold is enough, the heat of the equipment cannot be dissipated. Centralized air conditioning is to use the air duct to supply air, rather than the static pressure air reservoir, the air supply uniformity is poor, so the centralized air conditioner is not suitable for use in the monitoring and command center.
The special precision air conditioner of the monitoring and command center fully considers the characteristics of the computer equipment, and on the basis of the same cooling capacity, the air volume is increased. In addition, it is sent back to the wind and air storage, which can send and return air evenly, and can take away the heat of the machine more quickly and effectively.
2), cold accounting
According to the user's analysis of the use of the monitoring command center, and considering the future development, the design of the maximum possible heat load in the monitoring command center is designed. Due to the unclear arrangement of internal equipment, the thermal load is temporarily calculated according to the total cooling capacity of 300W/m2, and the cooling capacity is temporarily estimated to be not less than 250 W/m2. The total cooling capacity of your monitoring and control center (35 square meters) is 87.7KW. .
(6) Realization of fresh air and smoke exhaust
The monitoring command center area is a fire compartment, and the airtightness is good. In order to ensure that the monitoring command center area maintains a certain positive pressure, it is necessary to introduce fresh air frequently. Considering that the monitoring command center has a small space and no staff is stationed in the office. A new wind turbine of 1500m3/h is used to achieve fresh air introduction. In the event of a fire, the heptafluoropropane gas fire extinguishing agent released in the protection zone will be discharged into the protection zone as soon as possible, so that the monitoring and command center will resume normal work.
(7) Integrated wiring system
The Monitoring Command Center Cabling System is a standard structured cabling system for transmitting voice, data, images and other information. A transmission network within a building or group of buildings that connects voice and data communication equipment, switching equipment, and other information management systems to each other. The physical structure of the integrated wiring generally adopts a modular design and a hierarchical star topology.
According to the actual situation and future development of the monitoring and command center, the integrated wiring system in the monitoring and control center is designed, and the twisted pair is laid by the underfloor trough. Data information points are set under the floor where each cabinet is placed. Consider placing two cabinets and multiple control PCs.
The network system mainly completes the expansion and transformation of the backbone network of the existing management gateway area, and improves the bandwidth of the backbone network. According to the service system, the WAN deploys professional independent flow control acceleration equipment, which is a two-way guarantee for bandwidth services of key services and audio and video traffic. For the reduction of redundant data, all protocols of the WAN are accelerated to ensure that each site simultaneously sends multiple monitoring images and video conferences to the headquarters.
1) Basic structure
According to the design principles of the international standard (ISO/IEC 11801), the wiring system will consist of a work area subsystem, a horizontal subsystem, and a management subsystem. In this solution, the high reliability, high-rate transmission characteristics, and expandability of the wiring system are fully considered.
2), work area subsystem
The work area subsystem consists of an information outlet, a jumper (a cable that connects the information outlet to the device). The total number of data information points is dozens.
In order to ensure the normal operation of the computer network system, all information sockets are a standard RJ45 six-class information socket, which can support 250M Hz information transmission. Different models of computers and terminals can be easily connected to the computer information outlet via the RJ45 standard jumper.
3), horizontal trunk subsystem
The horizontal subsystem consists of a wiring cabinet to the cable between the various work areas. All horizontal cables are all made of 6E flame retardant twisted pair cable. The horizontal cable numbers are fully woven and fabricated according to EIA/TIA 606 and protected with a waterproof plastic film.
4), management subsystem
The management subsystem consists of the wiring system (equipment subsystem) in the monitoring command center, responsible for the unified management of the floor and information channels. Mainly composed of jumper panel, jumper manager, jumper, cabinet (or rack). The layout of the management subsystem will have a major impact on future cable management. In order to achieve high reliability, the patch panels are all installed in the cabinet. It can meet the requirements of various computer network systems for wiring systems. Computer networks can form structural line connections through jumpers and support a variety of computer networks through various network protocols.
(8) Centralized monitoring system of the command center

With the principle of “safety, perfection, sufficient reserve conditions, high performance and price ratio, integration and easy operation”, we try our best to meet the actual needs.
A digital video management platform will be built to digitize the video surveillance images of multiple point-of-sale monitoring systems, and each uploaded multi-channel video signal will be uniformly monitored and managed in the command center large-screen display platform, and will be selectively concentrated in the main machine room. Video (not less than 48 channels). Design multiple sets of monitoring command center environment HD camera is integrated into the video management platform for unified management, and the key moment can be used as a conference camera to cut into the conference system.
1) The monitoring system is mainly composed of three parts: front-end signal acquisition, intermediate signal transmission and back-end signal reduction processing (ie, central control equipment located in the control room).
2) The front-end equipment is responsible for signal acquisition, main camera and other equipment. These devices come out to pick up images and data from the scene and convert them into signals that the central control device can handle.
3) The role of the backend device is to process the signals that have been collected by the front end. It mainly includes the main functions of switching, displaying and recording video signals.
4) The middle part of the front-end and back-end devices is the transmission system. This part mainly includes the use of coaxial cable, network cable and video transmission equipment to realize the function of transmitting video signals to the display device and transmitting control commands from the operator to the front-end device. In the choice of transmission system, it is necessary to choose according to the actual situation.
