What Role Does Cloud Computing Play in the Field of Smart Home

Intelligent decision is the mainstream trend in the field of consumer electronics. As long as all products can be powered on, they can basically be related to intelligence. Not to mention mainstream products such as mobile phones and televisions, even household products such as refrigerators, washing machines and air purifiers are now related to intelligence, which together constitute the new concept of smart home.

To achieve intelligence, it is obviously not enough to rely on the built-in intelligent operating system. In the future, modern science and technology will continue to create miracles and constantly improve our lives. Nowadays, with the rise of the Internet of things, smart home has also made great progress. From wired mode to wireless mode, the operation is more concise, convenient, safe and reliable. If combined with cloud computing technology, smart home will be promoted to a new height.

Cloud computing is the increase, use and delivery mode of Internet-based related services. It usually involves providing dynamic, scalable and often virtualized resources through the Internet. Cloud is a metaphor of network and Internet. In the past, cloud was often used to represent telecom network in the figure, and later it was also used to represent the abstraction of Internet and underlying infrastructure. In a narrow sense, cloud computing refers to the delivery and use mode of IT infrastructure, and refers to obtaining the required resources through the network in an on-demand and easy to expand way; Guangyi cloud computing refers to the service delivery and use mode, which refers to obtaining the required services on demand and easy to expand through the network. This service can be it, software, Internet related, or other services. It means that computing power can also be circulated as a commodity through the Internet.

Cloud computing features

1. Integration of computing resources to improve computing power of equipment

Cloud computing centralizes a large number of computing resources into a public resource pool and shares computing resources through multi master leasing. Although the service level of a single user on the cloud computing platform is affected by various factors such as network bandwidth, and may not be better than the services provided by the local host, from the perspective of the whole social resources, the overall resource regulation reduces the peak load in some areas and improves the operation rate of some abandoned hosts, so as to improve the resource utilization rate.

2. Distributed data center ensures system disaster tolerance

The distributed data center can back up the user information in the cloud to the geographically isolated database host, and even the user cannot judge the exact backup location of the information. This feature not only provides the basis for data recovery, but also makes the attacks of network viruses and network hackers lose their purpose and become futile, which greatly improves the security and disaster recovery ability of the system.

3. Software and hardware are isolated from each other to reduce equipment dependence

The virtualization layer separates the application software above the cloud platform from the infrastructure below. The maintainer of technical equipment cannot see the specific application running in the equipment. At the same time, for users of the software layer, the basic equipment layer is transparent, and users can only see all kinds of virtual devices in the virtualization layer. This architecture reduces device dependency and makes it possible for dynamic resource allocation.

4. The modular design of the platform reflects high scalability

At present, the mainstream cloud computing platforms integrate software and hardware devices and middleware software with different functions at each layer according to SPI architecture. A large number of middleware software and devices provide common interfaces for the platform, allowing users to add extension devices of this layer. Corresponding interfaces are provided between some clouds to allow users to migrate data between different clouds. Similar functions meet the needs of users to a greater extent and integrate computing resources. It is one of the development directions of cloud computing in the future.

5. Virtual resource pool provides elastic services for users

The cloud platform management software will dynamically adjust the integrated computing resources according to the specific conditions of application access, including increasing or reducing the requirements of resources. Therefore, cloud computing has a very good application effect for applications with unsteady demand, such as large demand fluctuation and phased demand. In the cloud computing environment, the regular demand can be allocated in advance through prediction in advance, and can also be adjusted in real time according to the preset rules. Elastic cloud services can help users get computing resources to meet their needs at any time.

6. Pay on demand to reduce use costs

As a representative of cloud computing, providing services on demand and paying on demand is an indispensable part of all kinds of cloud computing services. For users, cloud computing not only saves the purchase, operation and maintenance costs of infrastructure equipment, but also can continuously expand the ordered services according to the needs of enterprise growth, constantly replace more suitable services, and improve the utilization of funds.

Generally speaking, the intelligence level of traditional home appliances is very weak, and the data storage capacity is very small. With the support of the cloud computing system, the intelligence of home appliances will mainly come from the cloud computing center, All home appliance terminals communicate with the cloud computing center through the network, transfer the current working state to the cloud computing center, and use the powerful computing power and storage power of the cloud computing center to provide intelligent computing support for the terminal. In this way, the home appliance system realizes intelligent integration and management, and the air conditioner can automatically provide indoor temperature with appropriate awareness, Windows can be opened and closed automatically according to the change of weather, so that the original rigid family equipment has intelligence, so that objects and objects, objects and people can interact effectively, and all kinds of equipment can provide more intimate services for the owner's life.

2. Home IOT

In the smart home Internet of things, cloud computing technology is the most core and important part. According to the architecture of the Internet of things, the home Internet of things is divided into perception layer, network layer and application layer, and cloud computing controls the whole system of the application layer. Cloud computing technology reduces the hardware investment capital of smart home and puts a lot of processing outside the home. At the same time, it also provides the possibility for complex computing inside the home. With the help of human factors engineering, psychology, clinical medicine, nutrition, language recognition and other technologies, the cloud perception model of smart home is established through the home public cloud computing server, Realize user habit perception, emotion perception, health perception and language perception within the family, and provide third-party interfaces for family providers to provide specific environmental services, health services, distribution services and other services convenient for people's life.

3. Family security

Cloud computing technology has the characteristics of real-time sensing and ready positioning. Therefore, the home cloud terminal equipment composed of cloud computing technology can carefully analyze and process the signals sent by various wireless or wired devices installed in the home, such as smoke detection sensors, emergency alarm buttons and other alarm devices, and transmit them to the resident's mobile phone or computer, Users can confirm the alarm information through mobile phone or computer in order to deal with the accident in time. The security cloud composed of cloud computing and Internet of things has transformed the security industry from "intensive security" to "intelligent security", from single function product to multi-sensor terminal integration, from single variable detection to comprehensive perception of the surrounding environment, from passive defense to active defense based on model research and judgment and situation analysis, so that residents can automatically take security precautions after leaving the room, After swiping the card at the door of the unit, the resident will automatically disarm, and can automatically turn on the light, open the curtain, open the water heater, etc. after the child goes home and swipes the card at the door of the unit, he can set whether to send information to the designated mobile phone, etc. It not only plays a better role in security, but also provides residents with a rich and colorful life.

4. Remote control

Cloud computing technology can provide applications across different networks and can support various types of terminals and various Internet applications. Therefore, by using mobile phones or computers, you can understand the operation status of various electrical appliances and security equipment at home at any time and anywhere, and control all equipment at home according to the wishes of users, so that residents can get a suitable temperature when they return home, You can drink hot water or take a hot bath. You won't be in a bad mood because of the fatigue of the day, which brings a good mood to the residents.
