Home improvement wiring first family comprehensive wiring Raiders

Nowadays, the Internet profoundly affects people's work, study and life. We not only use the Internet in work units and schools, but also in the family life. For ordinary network users, you may only know how to use it, but you do n’t necessarily know the actual network wiring. In units and schools, you do n’t have to care about what the network wiring is, but you need to care about the network wiring at home.

The concept of home wiring

Home wiring is a big project. The reason why it is not big is that this kind of project is too small for the network company, and it is generally unwilling to accept such a project, unless it is a large-scale integrated wiring of the community; In terms of wiring, it is a very professional and complicated project. Unless it is a well-designed residential broadband integrated wiring, otherwise the network wiring encountered in the ordinary new home renovation project will be solved by the owner himself.

The home network wiring is not a problem that any decoration company or decoration engineering team can solve, which I feel very much. The author has encountered troubles in carrying out computer network maintenance for home users many times. Many home network cabling is the network cabling carried out incidentally in the decoration project, there are many problems left without the guidance of professional network engineers. For example: the cable sequence is wrong; the information module is wrong; some are even more outrageous, connecting all the colored network cables and white cables into two strands, like two wires; the cable design is combined with strong electricity; the material is inferior and many more.

Today's home decoration is a big project, with civil decoration, water and gas pipelines, electricity and various wiring. In terms of wiring, in addition to wiring, there are cable TV cables and telephone lines, audio lines, video lines and network lines. In addition to power lines, these cables are called "weak current" and transmit various signals. We must build a multi-functional, modern, and highly intelligent home environment. This is the necessary wiring. Weak current integrated wiring requires professional engineers to make comprehensive and reasonable planning, design and construction for the owner. Only in this way can the overall home decoration be beautiful, orderly, practical, convenient for current use and future expansion.

Home integrated wiring system

The home integrated wiring system refers to an electronic system that centrally controls the design of networks, televisions, telephones, multimedia audio and video, etc. The integrated wiring system is composed of a household information access box (or wiring box), signal lines and signal port modules. Various cables are centrally controlled by the information access box. The signal lines and ports are the "neurals" of various application systems And "nerve endings".

The role of the information access box is to centrally control the input and output electronic signals, and various lines can be jumped in the box to achieve the path. After the integrated wiring is put into use, the line is usually allocated as needed to control the specific attributes and functions of the line, so that it is not necessary to change the line or even destroy the original decoration.

Ordinary information access box can control at least three kinds of electronic signals of cable TV signal, telephone voice signal and network digital signal; and the higher-level distribution box can control video and audio signals, if the community where the house is located provides corresponding services , Can also realize a series of functions such as electronic monitoring, automatic alarm, remote water and electricity gas meter reading. Various signals have corresponding function interface modules in the information access box to manage the connection of their respective lines. The information access box management principle is very similar to the central cabinet of the computer network.

The signal line transmits various electronic signals. These signal lines include: twisted pair (network line), coaxial cable, telephone line, audio line, video line, and various signal lines and control lines for security and automatic meter reading of water, electricity and gas. The signal port is connected to the terminal equipment. Such as: televisions, telephones, computers, switches, anti-theft alarms, automatic meter reading devices, etc.

Several major component modules of home integrated wiring

The composition module of the home integrated wiring is the functional module bar of the information access box. They manage the connection of various signal inputs and outputs. All the lines from the interface sockets in all corners of the room are connected to the corresponding functional modules. On the back, some modules have front sockets, which are consistent with the corresponding sockets in the corners of the room.

It also includes interface modules (commonly known as sockets) in each room.
1. Network module

The network module is composed of a group of 5 types of RJ45 jacks, which mainly realizes the jumper connection to the computer network cable entering the room. The five types of network cables from the room information jack are marked on the corresponding sockets on the back of the module according to the color code of the pair. The RJ45 jack on the front panel is connected to the small network switch through the RJ45 jumper. We can install a 5-port small switch in the information box, preferably a switch with an iron shell, which is conducive to heat dissipation through the box. ADSLMODEM can also be placed in the box.

2. Telephone module

The telephone module and the data module are actually the same. It also uses a set of Category 5 RJ45 jacks to multiplex the output of the external telephone line that enters the room. machine. This module adopts 5 types of RJ45 interface standards. For example, if the indoor wiring uses five types of twisted pairs, it can also be used for computer network connection.

In the actual wiring project, the network cable is often used as the horizontal wiring of the phone. When installing, a pair of blue and white wires among the four pairs of five pairs of twisted pairs are used as the phone. When using, just plug in the RJ45 jacks at both ends RJ11 telephone line is enough. In other words, the Internet and the telephone may be common and back up each other. It is a two-way approach.

3. TV module

The TV module is actually a cable TV distributor. As shown in Figure 4, this module consists of a professional-grade RF one-to-four distributor.

4. Audio and video module

The audio-visual module can realize the audio-visual sharing of each room. As shown in Figure 5, the audio-visual module is composed of four sets of video and audio screw terminal blocks, which are one in and three out, and three dial switches correspond to the control of the connection of the three groups of outlets, and the signal output port and the signal input port are multiplexed or disconnected. .

Connect video and audio (video: V, right channel: R, left channel: L) input signal line to the port, and output signal line to the corresponding output port. Each output port has a set of three-digit up and down switch on the panel (corresponding numbers "1", "2", "3", closed down, marked as "ON") can control 3 outputs Multiple connection and disconnection of signal and input signal. In this way, a VCD / DVD player can be shared in multiple rooms.

5. Data / voice socket

As mentioned above, in the practice of wiring engineering, a unified super-five network cable wiring method is usually used for data and voice wiring, so that both ends of the line are also terminated with corresponding RJ45 information modules. Therefore, the data / language socket is a unified RJ45 dual-tone socket, one for the network and one for the telephone.

6. Video / audio socket

The audio and video socket panel contains a video port, a left channel, and a right channel (V / R / L).
