20-smart Wiring
It is not easy for programmers xdjm to buy a house. It has been laid by a developer or a second-hand house, and cannot be swallowed up by an installer, a building material dealer, a furniture dealer, or a soft contractor. We need to arm ourselves with knowledge and fight together with js to the end. Let's take a look at the fence home decoration series compiled by Leng Shan.

20.1. Smart wiring Process
Http://video.liba.com/detail.php? Id = 69 & Aid = 1 the design and construction of smart cabling should follow the following principles: Smart cabling is a hidden project. The cabling layout should be comprehensively considered during the overall design based on functions and requirements, in order to avoid the effect of subsequent renovations. The Weak Current engineer communicates with the home decoration designer to determine the wiring scheme and give the drawings. Weak Current cables include network cables, cable TV lines, telephone lines, AV lines, and audio lines. Specifications for Construction: 1. PVC fire-retardant tubes should be set during cabling, and cannot be replaced by metal tubes; 2. telephones and network cables can share one pipe, and cable TVs must take one pipe. The sound line and wide line cannot be connected. Dedicated connectors or splitters must be used for telephones and network cables. 3. the pipe line must be horizontal, horizontal, and vertical. In case of bending, use an elbow to avoid cable twisting. 4. The minimum horizontal distance between strong and weak current is 30 cm. Installation of distribution box: 1. Standardized Products separated from the cabinet and modules should be used, which can be changed, upgraded, and expanded. 2. Weak Current signals are most vulnerable to interference. They must have a dual-shielded structure, that is, the outer iron box is shielded, and each module in the inner layer is independently shielded. 3. Strong power supply is not allowed in the distribution box. Only external power supply can be introduced with low voltage. 4. Install the module after completing all the renovations. 5. After the weak current is properly arranged, use professional instruments to detect and ensure smooth signals. Quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
20.2. Classification of smart WiringHttp://video.liba.com/detail.php? Id = 68 & Aid = 1 there are more and more weak current systems in daily life. All weak current cables are hidden in advance and managed in a uniform manner using multimedia distribution boxes for home use, which can save the trouble of pulling bright cables in the future. The multimedia distribution box consists of modules and extended interfaces for computer data, telephone branches, cable TV, and signal collection, respectively controlling broadband connections, telephone lines, cable TV video signals, and doorbell intercom access control, security alarm and other functions. There are three types of configuration by function: 1. Basic type, which has the following functions: Broadband Network, cable TV, and telephone. This can meet the basic needs of home Internet access, telephone calls, and cable TV reception. 2. comfort, functions in addition to broadband network, cable TV, telephone, home theater, video sharing, background music, etc., to meet the basic needs, to enjoy the home theater surround audio system, TV programs and music can be shared in each room. 3. luxury, features not only broadband network, cable TV, telephone and home theater, video sharing, background music, lighting control, security system, etc., each room can be independent or share music, adjust the volume freely and adjust the lighting atmosphere according to the environment. Smart anti-theft alarm is a high-end configuration. It should be noted that you should consider the area, actual needs, and economic capabilities for the configuration, and try your best to reserve development space.
