An example of network integrated cabling

The past wiring method is to the various facilities of the wiring design and construction, such as telephone systems, fire, security alarm systems are independent. A high degree of automation in the building, a variety of line including, not only difficult to manage, cabling high cost, and lack of function, not adapt to the needs of the situation. Integrated wiring is to take these shortcomings and adopt standardized measures to achieve a unified material, unified design, unified wiring, unified installation and construction, so that the structure is clear, easy to centralized management and maintenance. So now the new building, integrated wiring is a trend, but also essential infrastructure.

The integrated wiring system is a standard structured wiring system for transmitting voice, data, images and other information. is a transmission network within a building or complex that enables voice and data communication devices, switching devices, and other information management systems to be connected to one another. The integrated wiring system uses the structured wiring way, the computer system, the telephone system, the building intercom, the surveillance system synthesis a unified structure, the unified management entity, has completely solved the data high speed transmission, the line interference and the electromagnetic radiation and so on. Small Ocean Building network wiring is the category of intelligent building integrated wiring, this work in the small ocean floor of the civil engineering, at least the pipeline is the same.

Demand analysis

Small Ocean Building network wiring can include: Computer network system, security system, telephone system, CCTV four kinds of wiring system. Because the current technology development makes the security system can "run" on the computer network, so this network wiring system only computer network system, telephone system and CCTV three kinds of wiring. But at present in the practice is often in the twisted pair line also "runs" the telephone line, namely uses the double line line four pairs of lines in the two pairs of lines which are not actually used. So, the top three network systems have a single twisted pair of wires, which makes our wiring engineering greatly simplified.

We are here to introduce a two-storey villa, telephone line access is on the first floor of the living room, upstairs downstairs there are two rooms need integrated wiring, we will need to cloth a comprehensive signal transmission pipeline, set network, telephone, television system in one. We will use the current popular broadband access mode--ADSL. In this way, ADSL modem and wireless router are placed in the living room. ---http://bianceng.cn (computer science)

Equipment requirements

1. Pipe Groove and Accessories

In the network integrated wiring, we often use PVC wire pipe groove as the protection of the cable pipe groove. For a wiring with only four information points, we need to choose the appropriate pipe groove according to the actual cable total diameter. In addition, we also according to the situation in the corner of the need for a number of pipe elbow, and at the end of the pipe Groove also need to square dark box, the following information module with the information panel will be installed here. (Note: Some products of the information panel will also provide a square dark box)

2. Super Five class 4 pair shielded twisted pair cable

In such a home environment, a variety of power lines criss-cross, microwave ovens and other electrical appliances work will also have electromagnetic interference, the summer thunder and lightning weather will often patronize such a single-family villa. Therefore, we choose to have the electromagnetic protection of super five type shielded twisted pair. (Figure 1)


3. Super Five type of RJ45 information socket module

Information module is in the integrated wiring is often used in the network accessories, it is in the user end of the cable, computer and other equipment will be a 1 meters long or so at both ends of the two sides dozen crystal head jumper with this information module connection. The use of Simon's Super five-type RJ45 information module, it has a benefit is not to use a dedicated line tool, as long as the twisted pair of the color label into the corresponding slot, buckle, and then use pliers pressure can be. (Figure 2)


4. Two-bit Information panel

The information panel is the installation equipment of the information module, and it is also the lid of the concealed square box. Here we choose the two-port information panel, one is the information mouth, one mouthful is the telephone mouth. (Figure 3)


5. Crystal Head

Crystal Head Here we choose to be RJ45 crystal Head, this enables us to unify the use in the RJ45 information module and the information panel, such convenient one network cable simultaneously over the data and the telephone installation, the appearance unification looks good, the telephone line's end also uses the RJ45 Crystal head to hit.

6. 75 Ohm coaxial cable and divider

75 Ohm coaxial cable and divider is a CCTV system signal transmission path, such a lot of products, we can choose to buy on the market on the line.

7. One flat screen TV panel (with TV connector module)

This is the TV Jack panel containing the television connector module, which is the terminal point of the CCTV system in each room. We also buy Simon's products, so the color looks uniform. (Figure 4)


8. Wireless router

Because the wireless router is now priced to replace the average broadband router, therefore, we recommend the purchase of wireless router as the "core equipment" of this network, it is a broadband router, wireless AP, small switch, firewall in one of the Tetraena equipment, in the home has a very high availability. Based on the Web interface Setup Way at a glance, a little simple network knowledge can be easily set up applications.

Wiring Engineering

The diagram below is the network Cabling system diagram for this project: (Fig 6)


In the basic construction of the villa, the integrated wiring of the network should be taken into account, that is, the cable should be concealed into the wall, in order to avoid the renovation of the wall. We want to embed the PVC pipe groove with suitable pipe diameter in the wall, the pipe groove and the twisted pair and coaxial cable. In order to reduce the amount of engineering and network supplies, we should make the structure of wiring centralized or close to the central location of the building.

Our wireless router is in the living room, and the total starting point of the network starts here, and the wireless router has four switching ports that can provide network access to just four rooms. So we have to install four sets of concealed information outlets and a TV panel in the living room location, each of the other four rooms are equipped with a set of dark-mounted information outlets and a TV panel.

We have said above, because the network cable can also be over the telephone line, so we choose to press A or B two pairs of lines to enter a RJ45 information module as the information point of the computer network. In addition to use a pair of end-use line to also hit another RJ45 information module, the line we hit in the middle of the position (our phone line is a RJ45 crystal head to fight, telephone line is also hit in the middle position). The information module after the line is buckled into the jack on the Information panel.

Closed-circuit system in the fork of the place to add a divider, so that we can in the fork of the place to install a dark box, the divider installed in the dark box, but pay attention to the purchase of the divider to be small enough to facilitate into the dark box.

Summarize:

After such wiring, all the networks, telephone lines and CCTV systems in this small building are concealed inside the walls, and we can see the long cables of any of these systems in addition to the wall surface of the room, and look neat and beautiful. In this way, this small building already has "three nets in the same" integrated wiring, Intelligent Home foundation of the basic network so built. Now the wireless network, although the road, but for the high speed and stability of the network, Wired integrated network cabling is the best choice, it can calmly deal with the future based on the computer network multimedia transmission.
