What are the contents of the integrated wiring construction? Which big brother and sister knows? Tha

Weakly electrical? Weak current includes a lot of content, such as power cables, data cables, etc., what tube to wear, tube size, tube placement, path. Wait a minute. You can find the relevant documents in the library, and it will be clearer.

The integrated wiring system includes six aspects: work area subsystem, horizontal subsystem, trunk subsystem, management subsystem, equipment room subsystem and building group trunk subsystem. They are relatively independent and form subsystems with their own modular functions to form an organic and integral wiring system.

1. Workspace subsystem.

Including offices, offices, technical rooms, computer rooms and other areas that need equipment, computer terminals and other equipment and the corresponding equipment. The work area subsystem is located between the user terminal equipment, including the first machine, computer terminal, monitor, data terminal, etc., and the information socket of the horizontal subsystem, and plays the role of a bridge.

2. Horizontal subsystem.

It is a system composed of cables, information sockets, transfer points and supporting facilities between the distribution frame and the information socket in the work area on each floor, and the function is to connect each information point in the floor with the floor distribution frame, generally on the same floor, and connect the cable from the floor distribution frame to the information socket in each work area.

3. Trunk subsystem.

The vertical trunk subsystem refers to the system composed of cables and supporting facilities between the main exchange room and the distribution frame in each building. Form a trunk feed network. The backbone subsystem provides the backbone cable routing of the building, which is the nerve center of the integrated wiring system and realizes the connection between the main distribution frame and the intermediate distribution frame.

4. Management subsystem.

Management is really the regulation of the wiring equipment and cables in the equipment room, the exchange room and the work area according to a certain pattern to mark and record. The content includes management methods, logos, color codes, cross-connections, etc. The management subsystem adopts the methods of cross-connection and interconnection to manage the cables of the vertical trunk cable and the horizontal wiring subsystem of each floor, and provides a connection means for connecting other subsystems.

5. Subsystem of equipment room.

The equipment room is the installation site of the building's telecommunications equipment and computer network equipment, as well as the building's wiring equipment, as well as the place for network management. For the integrated wiring engineering design, the equipment room is mainly to install the main wiring equipment, switches, computer hosts, access network equipment, monitoring equipment and equipment other than strong current equipment and its incoming line.

6. The trunk subsystem of the building complex.

Institutions that are large or important in nature, such as a business or a school, usually have several adjacent buildings or non-adjacent buildings. They have language, data, image and monitoring systems associated with each other, which can be connected together with various supporting devices using transmission medium cables or fiber optic cables to form a single system.

In order for multiple geographically diverse computer systems to work together to exchange information and share resources, a common language must be used to interconnect multiple geographically dispersed computer systems through communication channels and devices. What is communicated, how it is communicated, and when it is communicated, must follow some mutually acceptable rules.

After the implementation of the integrated wiring system, the wiring system will be able to adapt to the development of modern and future communication technology, and realize the unified transmission of voice, digital communication and other signals. The cabling system can meet the requirements of various applications, that is, any information point can be connected to different types of terminal equipment, such as computers, printers, computer terminals, fax machines, various sensor devices and image monitoring equipment.

1) Work location

It is composed of devices between terminal devices and information sockets, including information sockets, socket boxes (or panels), connecting cords, adapters, etc.

2) Horizontal

Its function is to extend the trunk subsystem line to the user workspace. The horizontal system is arranged on the same floor, with one end connected to the information socket and the other end connected to the jumper between the floors. The horizontal subsystem mainly uses 4 pairs of unshielded twisted pair cables, which can support most modern communication equipment, and can be used when broadband transmission is required in some cases"Fiber-to-the-table"of the program.

When the horizontal area is quite large, there may be one or more satellite wiring rooms in this interval, and the horizontal line should be terminated to the equipment room and the terminal should be connected to the information exit through the satellite wiring room.

3) Vertical subsystem (backbone).

Usually it is from the main equipment room (such as the computer room, the program-controlled switch room) to the management room of each layer. It uses a large number of cable feeders or fiber optic cables, which are connected at both ends to patch racks in the equipment room and management room.

4) Equipment

It is composed of cables between equipment, continuous jumpers and related supporting hardware, lightning protection devices, etc. The ideal setting is to design the computer room, exchange room and other equipment rooms on the same floor, which is not only easy to manage, but also to save investment. Of course, it is also possible to design multiple equipment rooms according to the specific conditions of the building.

5) Administration

It is a bridge between the trunk subsystem and the horizontal subsystem, and at the same time can provide conditions for the same layer networking. These include twisted pair jumpers, jumpers (there are quick-connect jumpers and simple jumpers). In the cabling system that requires optical fiber, there should also be optical fiber patch racks and fiber optic patch cords.

When the location of the terminal equipment or the structure of the LAN changes, it can be solved by simply changing the jumper mode without rewiring.

6) Complex subsystem (campus).

It is a cabling system that connects the data communication signals of multiple buildings. It uses copper and fiber optic cables that can be installed overhead or along underground cable ducts (or directly buried), as well as electrical protection devices that prevent surge voltages from cables from entering the building.

The pre-construction preparation mainly includes technical preparation, pre-construction environmental inspection, pre-construction equipment and construction tools inspection, construction organization preparation and other links.

1) Familiar with the specification requirements of the engineering design, construction and acceptance of the integrated wiring system, and master the construction technology of each subsystem of the integrated wiring and the construction organization technology of the whole project.

2) Familiar with and review construction drawings. Carefully read the construction drawings, understand the content of the drawing design, and master the designer's high-end thinking.

3) Familiar with the technical information related to the project, such as the manual and product test report provided by the manufacturer, technical regulations, quality acceptance evaluation standards, etc.

4) Technical disclosure: The technical disclosure work is mainly carried out by the designers of the design unit and the project technical person in charge of the project of the engineering installation contractor. The main contents of the technical disclosure include:

design requirements and relevant requirements in the construction organization design;

performance parameters of materials and equipment used in the project;

engineering construction conditions, construction sequence, construction methods;

Safety precautions during construction.

5) Preparation of construction plan.

6) Preparation of project budget. The project budget specifically includes the bill of materials and the construction budget.

The first is the installation of the bridge, don't think that the bridge is a matter of strong electricity, the regular building, each with its own bridge;

Then dig the wall and bury the pipe, this project is outrageously large, if your customer ** does not budget this part of the cost, it is over.

The next step is to mend the wall. Buried pipes in chiseled places, and cement transported to more than ten storey high places is not a problem of one bucket or two barrels, one car and two vehicles. All of the above are basic works.

Then there is the wiring, the wiring includes ** TV computer, building intercom and access control management, parking management and barriers, monitoring, alarm anti-theft, fire protection, gas leakage, etc.

After the wiring is completed, the installation is debugged and the acceptance is organized.

And then, it's gone, it's done, hehe.

In the information society, a modern building, in addition to the **, fax, air conditioning, fire protection, power wires, lighting wires, computer network lines are also indispensable. The object of the cabling system is the transmission network within a building or building to connect voice and data communication equipment, switching equipment and other information management systems to each other and to connect these devices to external communication networks. It contains civil cables and related equipment connection measures between the internal and external lines of the building (network lines, ** office lines).

The wiring system is composed of many components, mainly transmission media, line management hardware, connectors, sockets, plugs, adapters, transmission electronic circuits, electrical protection facilities, etc., and various subsystems are constructed by these components.

The ideal cabling system is to support voice applications, data transmission, video and television, and ultimately comprehensive applications. Due to the comprehensive voice and data transmission network cabling system selected wires, transmission media is a variety of (shielded, unshielded twisted pair, optical cable, etc.), the general unit can choose the wiring structure and wire according to their own characteristics, as the wiring system, is currently divided into 5 subsystems, they are:

1. Workspace subsystem.

2) Horizontal trunk subsystem.

3) Management room subsystem.

4) Vertical trunk subsystem.

5. Subsystem of equipment room.

Security monitoring, community intelligence, intelligent buildings, network engineering, system integration, etc.

Monitoring, fire protection, communication, intelligence, etc.

The work area subsystem is a horizontal trunk subsystem composed of equipment between terminal equipment and information sockets, and is a management subsystem that connects cables from the floor distribution frame to the information seat of each user workspace, and is arranged in the room of the floor distribution line equipment.

The vertical trunk subsystem refers to the subsystem between the main distribution frame and the main distribution frame on each floor, which is a subsystem of the building group composed of the main distribution frame and various public equipment, and refers to the connection system of the main distribution frame extending to the main distribution frame of other buildings in the main building.

The wiring cabinet system is composed of floor distribution frames.

Including: building trunk subsystem, vertical trunk subsystem, horizontal trunk subsystem, etc.

It's so much that just saying the name feels like an advertisement. The landlord can go to the security ** to find Wuhan security company, there are many, you can compare the qualifications and the company's situation or go to Wuhan to find it online in the same city, there is a comparison to judge.

Hello, glad to answer for you. The relationship between the integrated wiring and the intelligent building The integrated wiring system is like a highway in the intelligent building, we can connect the 3A cables in the civil construction stage, the integrated wiring building, to the inner building to install or add what system, we can completely according to the time and needs, development and possibility to decide. Integrated cabling (PDS) is only a part of the smart building, and the integrated cabling system cannot be regarded as a smart building.

As long as there is a "highway" and a "integrated wiring system", what "car" you want to run and what system you want to get on, it will become very simple. The initial investment in the cabling system is only 3-5% of the building. The Concept of Cabling The cabling system is a standard structured cabling system for voice, data, image, and other information technologies.

The integrated wiring system is the transmission network within the building or building complex, which can connect voice and data communication equipment, switching equipment and other information management systems to each other, including all cables and related wiring components between the building to the external network or the connection point on the ** office line and the voice or data terminal in the work area. The structure of the integrated wiring adopts a modular design and a hierarchical star topology structure. The widely used building and building complex combined wiring system (PDS) structure can be divided into 6 independent systems (modules):

1.The work area subsystem consists of a connection (cord) from the end device to the information socket.

2.The horizontal subsystem connects cables from floor panels to information outlets in each user's workspace, typically on the same floor.

3.Vertical trunk subsystem (riser ??)Backbone subsystem) connects the main distribution with the patch panel system on each floor.

4.Administration ??subsystem) connects the vertical trunk cables with the horizontal cabling subsystem on each floor.

5.The equipment room subsystem connects various public equipment (such as computer hosts, digital program-controlled switches, various control systems, network interconnection equipment) with the main distribution frame. Integrated wiring design scheme 1
