Seven major subsystems of integrated wiring (establish an efficient network communication infrastructure)

1. Install and test the management subsystem. The management subsystem can monitor and manage the entire integrated wiring system in real time to improve the reliability and efficiency of network communication. Security subsystem Security subsystem refers to the system that protects the entire integrated wiring system.

2. Trunk subsystem: The trunk subsystem should be composed of trunk cables and optical cables from the equipment room to the telecommunications room, the building wiring equipment (BD) installed between the equipment and the equipment cables and jumpers.

3. Working area (terminal) subSystem: It is composed of the connection of the soft cable of the information socket and the terminal equipment, including assembly, connection and expansion of the soft cable, and them are built between the input and output sockets and the equipment terminals. Among them, the information socket is divided into wall, floor, table and soft base type.

What are the scope and functions of the six major subsystems of integrated wiring?

The scope of the six major subsystems of integrated wiring and their functions: the work area subsystem is an independent area that needs to set up the terminal, that is, a work area. The work area subsystem should be composed of the information socket of the wiring (horizontal) wiring system, connecting cables and adapters extending to the workstation terminal equipment. .

[Answer]: B There are six subsystems in the structured integrated cabling system, which are: work area subsystem: the purpose is to realize the connection between the work area terminal equipment and the horizontal subsystem, which is composed of cables connected to the terminal equipment to the information socket.

The integrated wiring system includes the following six subsystems: the work area subsystem. Horizontal subsystem. Manage the subsystem. Vertical trunk subsystem. Equipment room subsystem. Subsystem of the building complex.

What is the function of the horizontal subsystem in the network integrated wiring system?

According to the requirements of the entire integrated wiring system, the horizontal subsystem should be connected to the wiring equipment of the secondary handover room, handover room or equipment room to form a telephone, data, TV system and monitoring system, and facilitate management.

Connect the horizontal wiring subsystem and vertical trunk cable of each floor, and be responsible for connecting and controlling other subsystems. It is composed of cross-connection, interconnection and I/O equipment, which can locate communication lines and facilitate the management of communication lines.

The integrated wiring system is usually composed of six parts: the working area subsystem, the horizontal subsystem, the trunk subsystem, the equipment room subsystem, the management subsystem and the building complex trunk subsystem.

The reality of each subsystemThe current functions are as follows: The workspace subsystem consists of a connection cable and adapter extending the information socket of the wiring (horizontal) wiring system to the workstation terminal equipment. Each workspace is set up with a telephone interface and 1 to 2 computer terminal interfaces according to user requirements.

In the integrated wiring system, what is generally laid in the horizontal wiring subsystem?

According to the structural characteristics of the building, the best wiring scheme will be adopted.

's needs. The laying methods adopted by the wiring subsystem of the building complex mainly include overhead wiring, lane wiring, direct buried wiring, underground pipeline wiring, or any combination of these four laying methods. Among them, the laying method of underground pipe wiring can provide the best mechanical protection for the cable, which is the most ideal way.Therefore, choose option C.

Only connect to the information socket management room. In the integrated wiring system, the horizontal trunk subsystem consists of 4 pairs of UTP (unshielded twisted pair), which can support most modern communication equipment. If there is magnetic field interference or information retention, the twisted pair can be shielded. If high-bandwidth applications are required, optical cables can be used.

What are the pipe groove routing methods of the horizontal wiring subsystem of the new building

Direct buried pipe type. First, go through the inner line groove of the ceiling, and then go through the branch pipe to the information exit.

After the underground pipe groove system is built at the same time as the building, its routing and location generally cannot be changed. Therefore, when designing, the pipe groove system should have a certain degree of flexibility.

The horizontal subsystem The wiring pipe of the horizontal subsystem consists of two parts: one part is the bus channel where the horizontal transmission medium is placed on each floor, and the other part is the branch pipe or wire channel that leads the transmission medium to the information interface of each room. A transitional connection is required from the bus channel to the branch channel or pipe.

The wiring distance of the building complex subsystem is mainly determined by the distance between the two buildings. Generally, 1M of cable is reserved in each outdoor wiring well. There are four types of cable laying methods for building subsystems: overhead wiring method, direct buried wiring method, underground pipeline wiring method and tunnel cable wiring method.

In the building complex pipeline system, the average spacing of the junction well is about 180m, or the junction well is set at the main junction point. The junction well can be prefabricated or on-site pouring. Which kind of junction well should be indicated in the structural scheme.

If it is the introduction method of underground pipelines (including the introduction method of direct buried cables or direct buried optical cables through steel pipes), it is because the introduction pipeline passes through the main body or load-bearing structure of the building. To this end, in the engineering design and construction of the integrated wiring system, it is necessary to closely contact with the housing architectural design and construction units to cooperate with the negotiation to solve the following problems.
