How to wire the smart home? What devices do smart home wiring require?

With the continuous development of the smart home industry, the constant landing of the concept of intelligence has caused many consumers to become curious about smart homes. More and more users are beginning to consider smart home factors in their home improvement and purchase. However, if you want to build a good smart home environment, proper smart home wiring is essential, then how to do smart home wiring it? What devices do you need for smart home wiring?

Which devices are needed for smart home wiring?

1, twisted-pair (twisted-pair)

Twisted pair is now the most common transmission medium and consists of two mutually insulated copper wires, typically 1 mm in diameter. The two wires are twisted together in order to prevent their electromagnetic induction from interfering signals in adjacent pairs. The current twisted pair cable generally includes four twisted pairs, specifically white orange/orange, white blue/blue, white green/green, white brown/brown. The common twisted pair has box and shaft packaging and is 305 meters (1000 feet) long. At present, the domestic market that sells the most is the 305-meter-long cable carton package super five twisted pair.

2, rj45 module (modular)

There are four basic types of modular jacks. The 8-pin modular jack is usually called "rj45" and the 6-pin modular jack is usually called "rj11". Sometimes these "rj" devices are easily confused with something called usoc (universal service ordering codes). "rj" means "registered jack," and each of the basic sockets can be connected to differently constructed rjs.

For example, a 6-pin socket can connect rj11 (1 pair), rj14 (2 pairs), or rj25c (3 pairs); an 8-pin socket can connect rj61c (4 pairs) and rj48c. The 8 cores (keyed) can connect rj45s, rj46s, and rj47s. The fourth module socket is a modified 6-core version (modified module jack, mmj), which is a speech device designed by dec to connect dec. The integrated wiring module is used to terminate the cable and effectively connect with the jumper. Modules are used in distribution frames or home wiring boxes at the exit of the information panel.

3, distribution frame (pantch pannel)

The patch panel is versatile and economical and practical, and can be used for horizontal and vertical wiring, or directly connected to a hub and horizontal wiring system. With 12, 24 and 48 ports to choose from. The terminal is 110idc, with labels on both front and rear sides for easy identification. The product was designed for several 19-inch installations. The standard 19-inch rack type distribution frame is usually used for commercial wiring. The home wiring adopts six small units, which saves space, is easy to install, and has low cost. And can be installed in a small home wiring box.

4, crystal head

This accessory product is not included in the standard integrated wiring design and installation. It will only be a part of the finished jumper. When the home wiring, the original jumper may not meet the length and other requirements, the user may own Purchasing crystal heads and cables are made with special crimping tools.

5, the panel

This is a wide range of accessories that are widely used in home power and home appliances. When wiring, the panel is used to install the fixed module at the information exit location, and the domestic standard 86 bottom box is usually used. There are two kinds of single and dual ports. The common wiring panel is mainly installed with computer and telephone information outlets, and the multimedia information panel even has computers, telephones, catvs, and audio interfaces.

6, jumper (connecting line), also known as network cable

The copper jumper in the wiring is actually a short twisted pair crimped on both ends and used to complete the connection between the module, patch panel and active equipment. The common length of the jumper is 1 meter and 2 meters. 3 meters, 5 meters, 10 meters. It is recommended to use the original jumper for home wiring, because the original jumper process is rigorous and can withstand repeated plugging and unplugging.

7, optical fiber

An optical fiber is a small, flexible medium that transmits a light beam, centered on a light-transmitting glass core. Fiber optic cable consists of a bundle of optical fibers, simply referred to as fiber optic cables. Optical fiber cable is the most effective transmission medium in data transmission. It has the advantages of wide frequency band, good electromagnetic insulation performance and low attenuation. Commonly used cables include: 8.3μm core, 125μm outer layer, single mode fiber optic cable, 62.5μm core, 125μm outer layer, multimode fiber optic cable, 50μm core, 125μm outer layer, multimode fiber optic cable, 100μm core, 140μm outer layer, multimode fiber optic cable .

8, fiber to the home

Fiber-to-the-home (FTTH, fiber to the home) is a term used more recently to refer to a fiber access network that is connected to an access network in a home. From the perspective of technology development, FTTH is the ultimate solution for access networks. The fiber-to-the-home advantage is that the bandwidth is not limited to the user. This provides bandwidth guarantee for broadband services to enter the home. In addition, the fiber directly to the home, without external interference or leakage problems, outdoor equipment can do Passive, to avoid lightning, more reliable performance, power supply costs are also the lowest; but its disadvantage is that the cost is too high, can not be widely promoted.

9, coaxial cable

The coaxial cable is made of hard copper wire and covered with a layer of insulating material. This layer of insulating material is surrounded by a densely woven mesh conductor, which is covered with a protective material. There are two widely used coaxial cables. Baseband coaxial cable and broadband coaxial cable. Citywide or residential cable television networks use broadband coaxial cable when accessing homes and home content television systems. More broadband cable access currently being discussed is also based on broadband coaxial cable transmission.

10, audio video line

There are many audio and video cables involved in home entertainment systems: Audio cables include FM-amplified antennas, analog signal cables, and fiber-optic coaxial digital cables. Video cables include composite video and s-video cables. Coaxial cables used in cable TV are common RF cables. , There are professional speakers and so on. The prices of various kinds of wiring are quite different, especially the audio cables. The prices of speaker cables used by audiophiles are also very different. People in this circle are also using devices and cables that are price-producing to ordinary people. Ordinary home users actually have no need to replace the original audio cable, because most audio components are wired with other components and generally work well.

These connections are usually close to the device, not far away, but the audio cable may be longer, because in addition to the home theater system in the living room, speakers and speakers in other rooms need to be connected to the AV amplifier farther, this requires The home wiring system is used for the unified arrangement, and the high-quality speaker cables in the home wiring are used to connect the AV amplifier to the home wiring box, and then distributed to other rooms by the home wiring box. When the wiring is handled properly, do not tie the power cable to the speaker cable when wiring, because the AC signal will affect the signal. The wiring can not be tied, otherwise it will affect the tone. The wiring is too long to be shortened, and many wirings are directional. Do not make mistakes.

11, home wiring box

The home wiring box is the center of the home wiring management equipment, usually connecting and managing the module configuration box, communication module, video module, network module, sound module, system socket, cable, home intelligent management system and other parts, if the home AV center equipment Most of them are also equipped with dedicated cabinets. These devices can be placed together with home wiring equipment in a standard cabinet, such as a 39U standard cabinet.
