"Five Characteristics" Tells You What Smart Home Is

Smart homes are people's kind of living environment, making home life safer, energy-saving, smart, convenient and comfortable. The characteristics of smart homes can be summarized as operational arbitrariness, network diversity, device interconnectivity, function expansion, and system reliability.

Operational randomness

The arbitrariness of smart homes is mainly manifested in the diversification of operating modes. Smart touch screens can also be used. Scenario remote controls can also be used. Mobile phones or tablet computers can be used; time and place can be arbitrarily selected, and smart homes can be used at any time, any place and any time. Under the circumstances, it can realize timely and comprehensive understanding and control of any equipment inside and outside the room; the lighting effects can be personalized, and the lighting in the room can set different scenarios according to individual needs. For example, to set a "lights from the night" scene, in this scenario, you can set the bedroom wall lights, living room lights and bathroom lights to the "on" state. After the scene is set up, when you get up in the middle of the night, you only need to press a “light up night” scene key. The set light will turn on at the same time.

Network diversity

With the continuous advancement of the networked and intelligent era, home networks in smart homes are also diversified. The home network is mainly divided into two types: wireless network and wired network. Among them, the wireless network adopts different radio frequency technologies, ZigBee technology, and Z-wave technology because of different technologies. The wired network also includes bus technology and power line carrier technology. The bus technology includes KNX bus, LonWorks bus, and RS-485 bus. CAN bus and so on.

In addition, the home network is always connected with the Internet, the Internet of Things, and the wireless broadband network, providing the network foundation for smart home control.

Device connectivity

Various household appliances in the smart home can be interconnected through the home network, and can extend the operating period of the electrical appliances to avoid the peak of energy costs and save the electricity cost for the users. In addition, the smart home system's monitorable energy consumption mode is achieved through wireless communication, metering, and control technologies. Wireless communication methods that can be used include Wi-Fi or ZigBee. With ZigBee communication, household appliances can obtain energy price signals through meters or home energy management systems and send back energy usage measured by the control host's metering circuits.

Functional extensions

Smart home is still in the early stages of development. With the development of the national "Twelfth Five-Year Plan" and the rapid development of integration of telecommunication networks, computer networks and cable television networks, and the popularization and application of the Internet of Things, smart homes are also accelerating their development. The function expansion of smart homes is to meet the needs of users who do not ask questions, different grades, and different styles of home users. The software system of the smart home control host can be upgraded online, and the control function can also be continuously improved. In addition to intelligent lighting control, electrical control, security alarms, background music, video sharing, threshold control and remote monitoring, automatic watering sweeping, protection of the elderly and children, pet feeding, and emergency telephone help can also be achieved.

System reliability

The system reliability of the smart home is mainly manifested in the fact that the intelligent center control host is based on the design of the Internet+GSM mobile network dual-network platform. The double-network design greatly improves the reliability of the system even if it is used in some places where the Internet speed is low or unstable. It will not affect the main function of the system. Smart home systems use radio frequency (RF), ZigBee technology, wireless broadband (Wi-Fi), Transmission Control Protocol/Internet Protocol (TCP/IP) protocols for data transmission, and wirelessly send command lights, curtains, and electrical controls Use RF transmission commands for centralized monitoring and control.
