At present, friends in home improvement may all focus on the decoration of the family. They may not be too concerned about issues such as water and electricity. On the one hand, it was due to the renovation of the house. Only the question of how to decorate the home was left. On the other hand, it was not very important in this regard, and the focus should be on how to decorate the home.
Personally think that it is not true that the first consideration of home decoration is actually practical, and then it only involves the problem of beautifying the layout. Otherwise, if you leak a roof for a while, you will have a circuit short circuit and you will become even more messy.
Here I mainly talk about the purchase of home information boxes in home wiring. The family information box can also be said to be a household weak box. I don't say professional explanations. Generally, it is a collection box of all common lines except wires. The wires here refer to strong electricity, that is, family standards. The line through 220 volts, such as electric lights, household appliances and other lines. And what is left is the so-called weak current, which is about 36 volts to meet the line of equipment operation, such as computer-specific network switches, telephone extensions dedicated telephone exchanges, which are all 36 volts can make it The running equipment is the necessary equipment for modern home life.
The main function of the home information box is to centralize and manage the weak electricity in each room. It contains different modules. For example, a cable television splitter can branch a cable television line into four rooms and distribute it to different rooms. Affect its transmission performance. Commonly used modules generally include cable television splitters, telephone splitters, and network hubs.
Before purchasing a home information box, you can choose according to your own needs. Does your home need several telephones? Do not need shielding function? Several TVs? There are several computers? Whether all need to go online and so on. Some high-end homes may also need to consider the background music of the room, home security system, automatic water meter reading system and so on. After everything is settled, it is necessary to consider the following aspects:
First of all, is the information box clearly or concealed? The wall-mounted information box will expose the entire cabinet to the outside of the wall. This will not only occupy a space, but it is recommended that it be concealed. It is to bury the cabinet in the wall and only expose the panel. However, there is a problem to be paid attention to when installing concealed equipment. That is, how big is the size of the box you bought? If the box thickness exceeds 90mm, then the thickness of your home wall should be considered. If the thickness of the wall is 12cm, it cannot be concealed. Here is a simple explanation, if the wall thickness is 12cm, then 8cm is the brick, the remaining 6cm are the ash on both sides of the brick, and the ash is not sticky on the metal and plastic, so the thickness of the home wall is Only 12cm of friends, only consider the information box of the mounted series. However, at present, the thickness of most main building walls is 18cm to 24cm, so the average user does not have to worry about this problem. The concern is to buy the cabinet. Personally think that the home appliance products are doing quite well and meet this requirement. Compared with Putian Hongyan's products, the price/performance ratio is still good.
The second problem is to determine the various modules in the information box. Here you must be familiar with the function of each module, here I do not intend to introduce the function of the module one by one, just to quote the commonly used module and its purchase guide.
(1) Cable TV module: This module family is more commonly used. Its function is to distribute a cable TV outlet to several outlets and distribute it to different places. Individuals can watch their favorite programs without interfering with other people. This module is generally known to everyone, so I don't have much to say, but it should be noted that now digital TV is beginning to become popular, so we must also consider whether it has an upgrade function.
(2) Phone branch module: This module is also commonly used in the general family. A family's phone is generally a number of several extensions, several extensions can answer at the same time, this module is also generally understood, so I do not Speaking more, but here also involves a part of the phone shielding function, but the average family will not require the phone to be shielded.
(3) Computer Network Distribution Module: This module may not be well understood by some people. We will focus on this module here. The first module that comes out on the market can be categorized into three categories: information port module, hub/switch, and router. I don't use much professional terminology to explain here, just to say some popular understanding.
The information port module is mainly responsible for designing the computer in the home as a local area network. At the same time, only one computer can be used to access the Internet. The individual feels a bit restricting the function of the children's Internet access. Because the principle of the hub/switch is the same, I am merging in the same class. In brief, it is possible to share the Internet and several computers access the Internet at the same time. The difference is that the hub is "distribution according to work" and the switch is completely shared. Example: The same hub and switch provide 10M of bandwidth, and there are five computers connected at the same time, then the hub is to allocate 2m of bandwidth to each machine, and the switch is 10m of bandwidth.
The router is also called ip sharer, which allows several computers to share an ip address. That is, if you pull a broadband, you can share the Internet with several computers at the same time. Here also to mention is some attention when wiring, computer network cable than the average twisted pair, if it is to be on the four or five network cable, the ordinary pvc plastic tube can not be satisfied, it is recommended to use metal Class, but also larger than the ordinary pvc plastic pipe.
