Home decoration, furniture configuration, electrical equipment and other series related to the living room, of course, also includes a comprehensive system of geographical analysis considerations, these are part of the home.
And today's hot word " smart home ." Aside from the basic concept of Baidu, it is a modern smart home system : when a variety of home appliances in the home are connected through the family bus technology , it becomes powerful and highly intelligent. The two base points of the system are "logical judgment" and "accurate execution."
What are everyone watching in the smart home circle? Let Xiaobian and "Little Whites" introduce it.
First, intelligent hardware
High-profile comprehensive technology companies such as Google, Xiaomi and Haier, which are expanding their products, have announced their full entry into the smart home industry . In the short term, a series of smart home products with simple installation and use as highlights were launched.
However, careful users can easily find that, in the case of Xiaomi, the entire product line has not been significantly improved except for the traditional operation interface transplanted to the mobile terminal APP. Simply controlling one or two bulbs does not satisfy the complex lighting scenes in the entire home environment. On the contrary, this one-to-one operation of the item only adds a novel experience, still a distance from the complete concept of the smart home system.
Aiming at the development of longer-term and more perfect European and American intelligent systems, a bigger dispute has also been stalemate for many years on this battlefield without smoke. That is the bare power of wireless systems and cable systems.
Second, the cable
Cable system represented by KNX protocol
KNX is the European three major bus protocols EIB, BatiBus and EHSA merged to propose the KNX protocol. Based on EIB, it takes into account the physical layer specifications of BatiBus and EHSA, and absorbs the advantages of BatiBus and EHSA configuration modes.
1) Use of all scenarios from small systems in smart homes to large systems in building intelligence
2) Open agreement and international standard agreement language support product support of more than 400 brands worldwide
3) Provide farther, larger and more complex system stability services
4) Low energy consumption and near-infinite regional expansion
Third, wireless
Zigbee and Z-Wave protocols represented by wireless systems
1), ZigBee is more than Z-Wave is applicable, and can be used to deploy almost any short-range wireless function;
2), Z-Wave uses a simpler protocol, development is faster and simpler;
3), the range of Z-Wave is larger than ZigBee at the transmission power, and Z-Wave is more stable in some applications;
4), the signal interference immunity on ZigBee potential interference is more serious than Z-Wave.
Fourth, wireless VS cable
In terms of construction, the bus system is more complicated than the wireless system;
In terms of stability, bus communication is always more stable than wireless communication;
From the control function, the bus technology is more abundant and the wireless technology has a single function;
In terms of unity, KNX is a true European standard; wireless protocols are not yet standardized.
KNX has entered China for nearly ten years. Although the time is still short, it has made great progress and the momentum is hot. Now many large building intelligent lighting systems are controlled by KNX bus, such as Siemens, Schneider, HDL Hedong, GVS AV, ABB. Such as the KNX control system of the manufacturer.
Conclusion:
Next time, we will continue to introduce more hot words about the smart home industry, and strive to let the “Little Whites†who have not touched the smart home field learn more.
