Smart home is a home- based platform that is compatible with architecture, network communication, information appliances, network appliances, automation and intelligence. It integrates system, structure, service, management and control into one, high efficiency, comfort, safety, convenience, energy saving and health. Environmentally friendly home environment. With the improvement of living standards, intelligent home improvement has appeared in the lives of a very small number of people, but this kind of dynamic intelligent design is still out of reach for many consumers. In the more developed urban smart home market in China, It has begun to take shape, and in some areas where the economy is relatively underdeveloped, smart home decoration is still in its infancy. With the development of economy and people's pursuit of quality of life, smart homes will gradually enter more families and lead the fashion trend of decoration. . So, do you have a clear understanding of the main points of the wiring system during smart home renovation?
First, the LAN system
The era of information networks has had an important impact on home life. We should keep up with the pace of the times as a small local area network for new homes to cope with the needs of family Internet access, information appliance access networks, and remote network monitoring. To set up a small local area network at home, you only need to apply for an Internet broadband line, so that each room can use the computer to access the Internet at the same time. In addition, with the trend of home appliance networking, network video and audio centers, network refrigerators, network microwave ovens, network video surveillance will appear one after another, these devices can find the nearest network interface access network.
Wiring points: The LAN we want to build is a star topology. Any node or connection cable failure will affect only one node. RJ45 wiring panel module with total control function installed in the information access box, all networks The line from the socket is connected to the rear of the wiring panel. There should also be a small network switch installed in the information access box, which is connected to the front interface of the wiring panel through the RJ45 jumper.
In order to reserve the network information interface for the Internet and the large number of network information appliances that will be available in the future, we need at least two network interfaces for each room, one can be used as a network, one available phone, which is based on network and telephone multiplexing. And the requirement for mutual line backup. Including RJ45 wiring panel, twisted pair, RJ45 information module, I have to choose the current popular five categories, to meet the needs of the present and future.
Second, the cable TV system
In the home life, there may be not only a TV set in the living room, but also a TV set in the bedroom room. Especially now, the LCD big screen TV has greatly reduced the price, and some families also need to update the TV. The original TV can be moved to the bedroom. in. The cable television system can transmit analog or digital telephone signals and send signals to each room to watch both analog and digital TV programs.
Wiring points: Household cable TV systems should use better materials, should use dedicated two-way, high-shield, high-isolation 1000MHZ coaxial cable and panel, distributor, amplifier (required when more than 4 branches). The distributor should use high-quality devices marked with 5-1000MHz specifications.
The cable should be a 75-5 type, four-shielded physical foaming coaxial cable with good shielding performance from external interference signals to ensure the signal level of each room; the cable TV image is clear and there is no moire interference. Cable TV cabling is relatively simple. For ordinary commercial housing, we only need to install a one-four-fold distributor module in the home information box to connect the cable TV connected to the outside to the living room and each room.
Third, the telephone system
Although mobile phones are very popular nowadays, people are always used to chasing various preferential packages to change phone cards. Mobile phones may also be lost. This leads to our mobile phone number being ignored. Wired phones do not have this problem, plus its total tariff. It is lower than the mobile phone, so it is necessary to install a wired phone in the new home.
Nowadays, the domestic small-to-four, two-to-eight-small small-scale telephone program-controlled switches are very cheap, and the price is only between 100 and 200 yuan. Therefore, it is possible to install a small-scale telephone program-controlled switch at home. After installing a small telephone program-controlled switch at home, you only need to apply for an external telephone line so that each room can have a telephone. Moreover, it can communicate internally and dial the outside line. When the external power comes in, it will ring the bell until someone answers. If it is not your call, you can press the room number on the phone to go to another
one room. The small telephone program-controlled switch can also be used as a pager in a villa or duplex type.
Of course, there are ordinary telephone voice module panels that only use the information access box, but this type of panel can only share the external line of the access phone. When the phone comes in, the ringtones are the same, one room calls, other rooms can be monitored, no call is kept secret. Features.
Wiring points: Telephone system and local area network system wiring are wired according to the requirements of our “multiplexing and double backupâ€. The materials used in the cable and interface socket are the same, except that the connection method in the information access box is different. For the network twisted pair of the telephone, we use the color standard blue and blue and white line pairs to put the RJ11 crystal head. If a small program-controlled switch is used, it can be directly inserted into the interface of the program-controlled switch; if an ordinary one-to-one telephone module is used, Just plug the RJ11 crystal head into the phone module.
