Five smart home cabling methods during construction

Smart Home wiring generally has the following five methods:

1. Star Connection 2, bus connection 3, Power Line Carrier connection 4, infrared connection (IR) 5, Wireless RF) Connection

1. From the perspective of stability, star connections are the most stable and reliable, followed by bus connections, Power Line Carrier connections, infrared connections, and Wireless RF connections. Traditional security systems use Star connections, so they are also the most reliable.

Although bus connections also require wiring, when there are many points, the number of connections is less than that of star connections, and its reliable lines are generally acceptable. Power Line carriers and wireless connections have similar problems, mainly because of interference between adjacent families. From the technical point of view, Power Line carriers can adopt isolation and other technologies to solve mutual interference problems, it is difficult to solve mutual interference at a low cost in the wireless mode. Generally, only the frequency hopping technology can be used to solve the problem. In addition, there is also a power supply problem in the wireless mode, therefore, wireless should be a secondary option in household intelligence, especially security systems.

2. From the market perspective. Household intelligence has three markets: the new residential quarter market, the personal decoration market, and the old house renovation market.

New residential areas are generally in the unit of residential areas, requiring online alarms and information interaction. To achieve intelligence in the construction of a residential area, the requirements for wiring should not be based on the complexity of wiring, but on reliability. The entire Smart Community, even if there is a problem, is multiplied by the number of households. Generally, it is difficult to implement household intelligence in a residential area. Otherwise, acceptance and maintenance will be a big problem. Therefore, to achieve intelligence in a residential area, star-type connections should be the primary. The personal home improvement market requires more personalized family intelligence functions, but there is no need for networking. Since personal decoration is generally promoted by decoration companies, the sales can be achieved relatively high, so there are generally more functional requirements for the family, the number of points of implementation is also more. At this time, there are also requirements for system reliability and scalability. Because wiring is not a big problem at this time, the home decoration market should try to adopt star and bus methods. The old house transformation market generally requires less cabling as much as possible. At this time, the star and bus cabling methods sometimes seem to be insufficient. Therefore, the transformation of power line carrier and wireless in the old house market should be the main connection method.

3. As an actual Smart Home System, the best solution should be a mix of various wiring methods.

For example, security protection should adopt star connection as much as possible, while bus or wireless connection can also be used as a supplement. Power Line Carrier is difficult to use for security probe connection, because it cannot solve the problem of signal transmission during power failure. Star connections are the best solution for Integrated Information wiring. Lighting and electrical appliances other than information appliances, such as air conditioners and rice cookers, can be controlled using bus, power lines, wireless or infrared methods.
