With the improvement of living standards, home intelligence is a common demand, coupled with the advancement of the Internet of Things, I believe that integrated wiring will have a breakthrough in smart home . With the management and control of data between IoT technologies, the development of smart homes will achieve greater success, and at the same time, the comprehensive wiring will be a breakthrough in the field of smart home applications, prompting the integrated wiring to keep up with the pace of life and adapt to the rhythm of life. .
Five connection methods for smart home wiring
1, star connection 2, bus connection 3, power line carrier connection 4, infrared connection (IR) 5, wireless (RF) connection
First, from the perspective of stability, the star connection is the most stable and reliable, the bus connection is second, the power line carrier connection is again, the infrared connection (IR) is again, and the wireless (RF) connection is the worst. Traditional security systems are star-connected and therefore the most reliable.
Although the bus connection also requires wiring, when the number of points is large, the number of connections is less than that of the star type, and the reliable line is generally acceptable. Power line carrier and wireless connection have similar problems, mainly the interference problem between adjacent households. From the technical point of view, the power line carrier can use isolation and other technologies to solve the mutual interference problem, and the wireless method needs to solve each other at low cost. Interference is relatively difficult. Generally, only frequency hopping technology can be used to solve it. In addition, wireless has Power Supply problems. Therefore, wireless should be a secondary option in home intelligence, especially security systems.
Second, look at the problem from a market perspective. There are three markets for family intelligence: new residential market, personal home improvement market, and old home renovation market.
New residential areas are generally based on residential units, requiring networked alarms and information interaction. The intelligentization of the community in the construction of the wiring requirements should not be based on the complexity of the wiring, and reliability as the first requirement. The entire realization of a community is intelligent, even if there is a problem, it is the total amount of problems multiplied by the number of households. Realizing family intelligence in a community is generally not too complicated to implement, otherwise acceptance and maintenance will be a big problem. Therefore, intelligent implementation in the community should be based on star connections. The personal home improvement market requires more personalized home intelligence features, but no networking requirements. Since the personal home decoration is generally driven by the decoration company, the sales that can be achieved are relatively high, so the functional requirements for the interior of the home are generally more, and the number of points achieved is correspondingly higher. At this time, the reliability requirements of the system are accompanied by the expansion requirements. Since the wiring is not a big problem at this time, the home improvement market should adopt the star type and the bus mode as much as possible. In the old house renovation market, the wiring requirements are generally minimized. At this time, the star and bus wiring methods sometimes seem to be incapable. Therefore, the power line carrier and wireless in the old house transformation market should be the main connection method.
Third, as an actual home intelligent system, the best solution should be a mix of various wiring methods.
For example, security should use star connection as much as possible, and it can also be supplemented by bus or wireless. Power line carriers are difficult to use for the connection of security probes because they cannot solve the problem of signal transmission during power outages. Star connectivity is also the best solution for information cabling. Lights and controls other than information appliances such as air conditioners, rice cookers, etc. can be controlled by bus, power line, wireless or infrared.
