Home life in modern society is not only convenient and comfortable, but also intelligent, entertainment, and safe. This requires improving the good wiring for household appliances. Weak electrical wiring is the "nervous" in the home room, they pass a variety of circuit signals to various devices to achieve the above application requirements. However, ordinary owners of a layman may encounter some of the above-mentioned practical problems of weak wiring. How should the newly renovated interior arrange its weak current lines and wiring points? Newly installed rooms should be arranged as follows: mandatory, selectable, and optional weak circuits. The following are separately described: First, LAN system The information network era has had an important impact on home life. We should keep up with the pace of the times for the Xinju Group's small-sized local area network to meet the needs of the family's Internet access, information appliance access network, and remote network monitoring. To set up a small local area network at home, you only need to apply for a broadband Internet connection so that each room can use the computer to access the Internet at the same time. In addition, with the trend of networked home appliances, network audio and video centers, network refrigerators, network microwave ovens, and network video surveillance will appear one after another. These devices can all find the nearest network interface to access the Internet. Wiring points: The LAN to be built is a star topology. Any node or connection cable fails and only one node is affected. The RJ45 patch panel module that controls the installation of the information access box is used. All networks The line from the socket accesses the rear of the wiring panel. There should also be a small network switch in the information access box, which is connected to the front panel 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, and one can use the telephone. This is based on network and telephone multiplexing. And line backup requirements. Including RJ45 wiring panel, twisted pair, RJ45 information module, I have to choose the current super five categories, can meet the needs of the present and future. Second, the cable television system In the home life, there may not be only one television set in the living room. There should also be a TV in the bedroom. In particular, the large-screen LCD TVs will be greatly reduced in price. Some homes 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 every room. It can watch analog TV programs as well as digital signal TV programs. Wiring points: home cable television system should use better materials, should use a dedicated two-way, high shielding, high isolation 1000MHZ coaxial cable and panels, distributors, amplifiers (more than four branches required). Dispensers should use high quality devices marked with 5-1000MHz specifications. The cable should use the 75-5 type, four-shield physical foam coaxial cable with good shielding performance against external signals to ensure the signal level of each room; the cable TV image is clear and there is no moire interference. The cabling of the cable TV is relatively simple. For ordinary commercial housing, we only need to install a four-point splitter module in the home information box to distribute the cable television access from the outside to the living room and each room. Third, the telephone system Although mobile phones are very popular today, people are always used to chasing various preferential service packages and constantly changing phone cards. The mobile phone may also be lost. This results in our mobile phone number being undecided. Wired phone does not have this problem, plus its total tariff. It is lower than the mobile phone, so installing a wired telephone in a new home is still necessary. Nowadays, domestically produced small-size one-to-four, two-to-eight small telephone program-controlled exchanges are very cheap, and the quotation is only between 100 and 200 yuan. Therefore, it has become possible to install a small telephone program-controlled exchange at home. After installing a small telephone program control switch at home, you only need to apply for an outside telephone line so that each room can have a telephone. In addition, both internal and external calls can be dialed. When the external call comes in, the ringing is repeated until someone answers. If it is not yours, you can press the room number on the telephone to go to another room. Small telephone program-controlled switches can also be used as pagers in villas or duplex rooms. Of course, there is an ordinary telephone voice module panel that only uses the information access box. However, this panel can only share the incoming telephone line. When the phone comes in, the ringing tone will be the same, a room will be called, other room can be monitored, and no call is kept confidential. Features. Wiring points: The telephone system and local area network cabling are wired together in accordance with our “multiplexing and dual backup†requirements. The materials used in the cable and the interface socket are the same. The difference is in the connection method of the information access box. As a telephone network twisted pair, we use the color code is blue and blue-white line pair marked RJ11 crystal head, if using a small program-controlled switchboard, directly into the program-controlled switch interface; if using a common drag a few phone modules, Insert the RJ11 crystal head into the phone module. Fourth, home theater system Home theater systems are the first choice for modern home entertainment, and setting up a home theater system should be the choice of many families. A home theater is a home where you can enjoy the same or similar clear and colorful images as a movie theater. It is full of motion and sound effects. Home theater equipment is divided into two major video and audio. The video part is a very important part of the entire system. Usually it is served by a large screen TV or projector, where the projector needs wiring. The AV amplifier is the center of audio playback and features multi-channel sound reproduction. When it comes to multi-channel playback, it is inseparable from the standard of surround sound. The popular surround sound standards are: 1. Dolby Digital surround sound (5.1 channel); 2. DTS surround sound (5.1 channel); 3. DTS-ES Discrete surround sound (6.1 channel); 4, THX Surround EX surround sound (7.1 sound channel). The home theater speaker consists of five, six, seven, etc. each plus a heavy speaker. The main speakers and center speakers on the left and right sides can be wired without wiring, and the rear surround speakers and rear speakers should be wired. Wiring points: The home theater system cabling mainly includes the projector's video cable (such as VGA, color difference cable, DVI, HDMI) and speaker cable. Since it is a top-level home theater system, these cables are not connected, that is, one line goes to the end, and the connectors and lines are manufactured by the factory. Therefore, other wiring systems are independent, and they are generally only wired in the living room or study room. The length of the trace must be accurately calculated at the time of design in order to purchase the cable of the appropriate length, ensure enough pull-in place, and have sufficient margin in the center of the audio-visual equipment. Weak electrical wiring should pay attention to matters How to arrange your own wiring according to your needs? The modern wiring concept basically advocates the "star topology" structure, which is a substitute for the past "bus topology". The star topology emphasizes that each line is independent, which avoids a single point of failure causing the entire system to paralyze. The vast majority of weak home wiring is also the use of advanced star topology cabling, centralized convergence to the information access box to implement centralized management, convenient jumper, easy to expand, this is the main content of home wiring. However, we can't just generalize that any cabling is managed through the aggregation of information access boxes. There are also several systems where the system is independently wired. As mentioned above, infrared relay systems, home theater systems, and home background music systems are not required. Gathered to the information access box, they need to use independent wiring because of their unique features.
