【 Weak current College 】 smart home wiring of five connection method

1 star connection 2, bus connections 3, power line carrier connection 4, infrared (IR) 5, wireless (RF) connection

First, from the point of view of stability, Star connection the most stable and reliable bus connections, power line carrier connection again, infrared connection (IR), wireless (RF) connection. Traditional security systems are based on the star connection, therefore most reliable.

Bus connection while also requires wiring, but more in number, quantity than star connection, its reliable line generally acceptable. Power line carrier and wireless connection exists similar problems, mainly the adjacent interference problems between the family, from a technical point of power line carrier can be quarantined, and other techniques to solve the problem of mutual interference between the wireless way to low-cost solution to mutual interference between the relative difficulty, in General only use frequency hopping technology can truly solve coupled with wireless and power supply problems, wireless intelligent in the family should be a second election programmes, in particular the security system.

Second, from a market perspective. There are three market home intelligent: the newly built residential market, personal home market, brickwall market.

New residential areas and general community-units, the requirements for alarm, information interaction. Community under construction achieve intelligent on wiring requirements should not use the routing to the complex as a primary, and reliability-the first request. A community as a whole to achieve intelligent, even if there is a problem, are multiplied by the total number of issues. In the community would not be appropriate for a general family smart implementation too complex, or the acceptance and maintenance will be a big problem. Therefore in the community achieve intelligent should star connection-oriented. Personal home markets require more personalized home intelligent features, but there is no networking requirements. Because personal home is usually a decoration to lead, to achieve sales are relatively high, and so on domestic feature requires more generally, the implementation of the corresponding points. At this time on system reliability requirements as well as extensibility requirements, since routing not a big problem, home market should try to use a star and bus. Brickwall market General requirements for wiring to minimize the paramount to wiring. When the star and bus two routing sometimes seem too great, so the brickwall market power line carrier and wireless should be the main connection.

Third, as a practical domestic intelligence system, the best solution should be a variety of cabling can be mixed.

For example, security as far as possible the star connection methods, you can also use bus or wireless means, in such a way as to add. Power line carrier is difficult for security probe connection method, because there is no way to solve the power of the signal transmission problems. The star connections or information the best solution for comprehensive wiring. Lights and the in addition to information appliances such as air conditioning outside electric rice cookers, and other controls, can take a bus, Powerline, wireless or infrared, etc.
