What are the engineering planning requirements for intelligent computer room?

With the rapid development of intelligent systems, the scale of intelligent construction of more and more buildings is also expanding. Digitalization, networking and intelligence have become the mainstream construction concept, thus providing a safer, more comfortable and more convenient life. And the working environment. Among the intelligent subsystems, the computer room engineering is one of the foundations of many intelligent subsystems. It is of great significance to the stability of other intelligent subsystems and the convenience of later maintenance.

First, explain from the normative point of view what is the computer room project in the intelligent system. In the "Intelligent Building Design Standard" (GB/T50314-2006), there is a clear definition of the computer room project: "2.0.7 Computer Room Engineering (EEEP) engineering Of electronic equipment plant, a comprehensive project to provide installation conditions for equipment and devices such as intelligent systems to ensure safe, stable and reliable operation and maintenance of the building environment."

Generally speaking, the computer room project in the intelligent project must meet the requirements of temperature and humidity, cleanliness, power quality, lightning protection and grounding of microelectronic devices such as computers. The construction should conform to the "Design Specification for Electronic Information System Room" (GB50174- 2008), "General Specification for Computer Sites" (GB/T2887-2011) and other related specifications. In the case of someone on duty, the requirements for the sanitation and environment of the computer room staff shall be met, and the construction shall comply with the relevant specifications of the Code for Design of Heating Ventilation and Air Conditioning (GB50019-2012).

5 elements of the computer room engineering plan. In order to adapt to the above changes, the computer room engineering in the intelligent system emphasizes miniaturization, integration, and energy saving. Common construction measures include the following five points:

1. Information Facilities System (ITSI) adopts high IP network design

The information network system based on IP network has strong versatility and compatibility, and the transmission efficiency is high, which can simplify the design of each intelligent subsystem, and also has important significance for the design of streamlined computer room engineering. Take the video surveillance system with the largest amount of data transmission in real time as an example. The solution using IP camera: network storage (NVR or IPSAN) + network decoder, 500 channels of video storage and decoding management, only need 20U (that is, half of the 42U standard) The space of the cabinet). Analog video surveillance systems of the same size: DVR + video matrix + video splitter, at least 3-4 42U standard cabinets.

2, simplify the consolidation of workstations and servers

The video surveillance system, the card system, the building equipment monitoring system, etc. of the intelligent system generally require a server or a workstation. In practical applications, the above management server or workstation processes less data, has a lighter running load, and is more convenient to expand. Should not blindly pursue high performance, high configuration, in addition to increasing the initial cost of construction, will also increase the energy consumption of subsequent operations; should adopt the principle of "one machine multi-purpose, moderate configuration". For example: construction equipment monitoring system, intelligent lighting system, etc. can share workstations, such as screen display area is not enough, can use one machine multi-screen or large screen (24 inches or more) + small software split screen; card system, construction equipment monitoring system The server needs to be configured, and the virtualization technology can be adopted. One physical server virtualizes multiple operating systems and runs server software of different intelligent subsystem systems.

3, the video wall uses the pre-maintenance method

For example, a single-panel display body can adopt a "cabinet door" type design, which can "turn over" a single display body to maintain the same as "opening the cabinet door", which is simple and convenient; compared with the post-maintenance mode, it can save 0.8. M-1.2 m maintenance space, especially for small spaces.

4, UPS room should be set independently

In the layout of the square, considering the heat dissipation and noise of the UPS main engine operation, and the high risk factor of the battery, it will adversely affect the human body and the equipment. It is often separated by a certain distance or separated by a small space, which often wastes good planning space. If some irregular space is used, the UPS room can be set independently, and the irregular space can be fully utilized, and the influence of the battery on the peripheral equipment is also minimized.

5, UPS system should adopt the principle of unified planning

In some buildings, the computer room project is relatively scattered. The scheme of independently setting up the UPS main unit and the battery in different computer rooms is also very simple in the initial construction.
