Abstract: As we all know, the Internet of Things is an important part of the new generation of information technology. In today's society and in the future,

It plays a huge role and is widely used. Although the Internet of Things technology is not very mature at present,

However, some areas of research are still relatively advanced, such as home. So this time, I chose the Internet of Things in intelligence.

The topic of home application. In this paper, we will first introduce the related contents of the Internet of Things, including the understanding of the Internet of Things.

And the role of the Internet of Things, and then introduce how the Internet of Things is applied in smart home, as well as the current comments on smart home.

Finally, we will look forward to the future development of smart home and some corresponding changes that we can make at present.

Keywords: Internet of Things, technical framework, smart home, development prospect

First, the cognition of the Internet of Things.

The Internet of Things is an important part of the new generation of information technology, and it is an information carrier based on the Internet and traditional telecommunication networks.

Body, so that all ordinary physical objects that can be independently addressed can realize the Internet. It has a common object device,

The interconnection of autonomous terminals and the intelligence of ubiquitous services are three important characteristics. Its English name is "Internet of Things".

Therefore, as the name implies, "the Internet of Things is the Internet where things are connected". This has two meanings: one is the core of the Internet of Things.

And its foundation is still the Internet, which is an extension and expansion network based on the Internet. Second, its client extends and expands.

Exchange information and communicate with each other. So the definition of the Internet of Things is through radio frequency identification.

(RFID), infrared sensors, global positioning system and other information sensing equipment, according to the agreed agreement, any items and

Internet connection, information exchange and communication to realize intelligent identification, positioning, tracking, monitoring and management of commodities.

Manage the network.

From the technical architecture, the Internet of Things is divided into three layers: perception layer, network layer and application layer. The sensing layer is composed of various sensors.

And a sensor gateway. The function of perception layer is equivalent to nerve endings such as eyes, ears, nose, throat and skin, and it is the knowledge of Internet of Things.

The main functions of identifying objects and collecting information are to identify objects and collect information. The network layer is composed of various private networks, which mutually

Network, wired and wireless communication networks, network management systems and cloud computing platforms. , equivalent to the human nerve center and brain.

Responsible for transmitting and processing the information obtained by the perception layer. The application layer belongs to the Internet of Things and users (including people, organizations and other systems).

Interface, combined with the needs of the industry, realize the intelligent application of the Internet of Things.

At the same time, we should also note that there are three key technologies in the application of the Internet of Things:

1, sensor technology, which is also the key technology in computer application. As we all know, most of them.

The computer processes all digital signals. Since the advent of computers, sensors have been needed to convert analog signals into digital signals.

The computer can handle it.

2. RFID tag is also a kind of sensor technology. RFID technology is a combination of radio frequency technology and embedded technology.

RFID integrated technology has a broad application prospect in automatic identification and cargo logistics management.

3. Embedded system technology combines computer software and hardware, sensor technology, integrated circuit technology and electronic application technology.

Surgery is a complicated technique. If the Internet of Things uses the human body as a simple metaphor, sensors are equivalent to people's eyes, nose,

Skin and other senses, the network is the nervous system used to transmit information, and the embedded system is the human brain. After receiving the message,

To be classified.

Second, the use of the Internet of Things.

From the above understanding of the Internet of Things, the Internet of Things can realize the interconnection of things. But beyond that, the Internet of Things has its own.

His role:

1, in addition to the information exchange and communication between people, it also includes the communication between people and things, things and things.

Conduct information exchange and communication. Of course, the people here are still the main body. Because of the purpose of information exchange and communication between things.

Yes, it is still necessary to serve and be used by others.

2, in addition to the purpose of information exchange and communication, but also through the installation of information sensing equipment, such as radio frequency identification equipment.

Equipment, infrared sensor, global positioning system, laser scanner, etc. Everything is networked and convenient.

Identification and management.

From the above, we can sum up a general understanding of the Internet of Things: the Internet of Things is realized through the connection of sensors.

A network connected with things, in which information exchange and analysis can be realized; It can also be implemented in this network.

Intelligent control objects to meet the corresponding needs of the public.

Thirdly, the status analysis of the Internet of Things in smart home.

4. 1 Understanding of Smart Home

Smart home, or smart house. First of all, it needs to establish a communication network in a family to provide family information.

Provide necessary access, and under the control of the home network operating system, realize the connection through the corresponding hardware and execution mechanism.

Control and monitor all household appliances and equipment in the home network; Secondly, they must form a relationship with the outside world through certain media.

The communication channel for information exchange with the outside world of the family meets the requirements of remote control, monitoring and information exchange.

The ultimate goal is to meet people's needs for safe, comfortable and convenient work and life at home.

4.2 Main functions of smart home

(1) Safety protection and fire alarm automation

Safety protection and fire alarm automation are the most basic functions of smart home, because people care about themselves and their property.

Safety is paid more attention, and a basic starting point for choosing smart home is family safety and disaster alarm automation.

(2) Smart home appliances.

The intelligentization of household appliances is an important part of smart home. A remarkable feature of smart home is that it can be rooted.

According to the needs of households, intelligent control of household appliances and household appliances facilities can be realized flexibly and conveniently, and households can be freed from housework to a greater extent.

Emancipation in sports. With the development of society and the progress of technology, there will be more updated applications of smart home appliances.

(3) property management automation

By networking with the intelligent system of the community, residents can know the usage of water, electricity, gas, telephone and network.

Line monitoring. First, realize the automatic measurement of various expenses and reduce the workload of property management; The second is to facilitate users to collect fees by themselves.

I. control to avoid serious cost overruns; Third, telephones or other resources can be found in time and prevented from being stolen. Property management automation

Culture is a sign of community wisdom.

(4) Information and communication automation

General communication automation only realizes simple telephone automatic recording, fax automatic receiving or telephone reply; children

Intelligent communication can automatically dial 1 10, 1 19 alarm phone or the owner's office phone or mobile phone.

Such as communication tools. The content of communication information automation of smart home will be more extensive. Such as connecting a personal computer at home to a domain.

Network, Internet, make full use of computer network resources to realize community information service, property management service and online information search.

Inquiry, online business and other Internet functions. If conditions permit, telemedicine, distance teaching and consultation can also be realized.

Query reservation and other functions.

(5) Cooperation among various devices

Smart home system can provide more system-related functions. For example, when you are ready to watch TV, the lights in the living room change from

Adjust the brightness you like (realized by dimming control module) and automatically close the curtain (realized by curtain control module).

Turn on the TV, tune to your favorite channel, and so on.

(6) Environment and energy saving

Smart home can monitor indoor temperature, humidity, brightness and other environmental state values, and adjust them according to residents' habits.

To some extent, it can not only make the living space more comfortable, but also save energy. Not only that, but also through the wisdom of home appliances

It can also save water, gas and other resources.

4.3 Composition of Smart Home

There is no conclusion about the composition of smart home in academic circles. Based on various viewpoints, a complete smart home system not only has the following characteristics.

In addition to information equipment with various functions, it must also include the following modules:

(1) information processing module

In order to make independent information appliances realize information sharing and cooperative work, smart home system must have special

Information processing module of door. Its main function is to collect the working status and service requests of various household appliances in the family.

According to the real-time processing result, the result is sent to the function driving module.

(2) Communication module

If the information processing module is the brain of the smart home system, then the communication module is the nerve to realize information transmission.

According to the characteristics of home network, communication modules often use existing wiring (such as power carrier) or adopt wireless transmission (such as

Bluetooth, infrared), etc. Because different information devices have different transmission bandwidth requirements, practical communication modules are often used.

Multi-mode hybrid network.

(3) Function drive module

Function-driven module is the interface of information flowing into and out of various information devices. Because the products of various electrical appliance manufacturers are in

There are great differences in function and implementation, so the instructions of the information processing module must be translated into electricity through the function driving module.

The executable level signal of the device and various state information of electrical appliances can be converted into binary which can be understood by the information processing module.

Information.

(4) External information interface module

This module can be seen as a gateway for a family to the outside world (such as the Internet). There are all kinds of electric letters at home.

On the basis of information sharing, further realize the resource sharing based on the Internet, so as to further realize the depth of * * * sharing.

It will be a hot spot in the development of smart home system in the future. Because the home network usually does not use TCP/IP protocol,

Therefore, the most basic function of the external information interface module is to switch from TCP/IP protocol to various home internal network protocols.

Change.

Fourth, the lack of intellectual homes.

The spontaneity and blindness of market economy, on the one hand, caused the rapid growth of smart home industry, on the other hand,

On the one hand, it also gave birth to certain defects. For new things, their advantages are often obvious, while their defects are invisible.

From the perspective of industry development, these defects hidden behind the prosperity will seriously hinder the future development of the whole industry.

At present, the defects of smart home industry can be summarized as "mental retardation" and "complexity".

1, the so-called "mental retardation" refers to mental deficiency. In addition to the computing and judgment ability of the device itself, smart home,

It also needs the linkage between devices to realize intelligence. Linkage is the shortcoming of smart home industry at present. as a result of

Our smart home system is not fully functional. Most brands can only realize security alarm, visual intercom and intelligent lighting.

Few functions can be combined and derived from each other, let alone linked, so its intelligence is greatly affected.

Reduce.

2. Complexity mainly reflects the complexity of product wiring, configuration and operation. There are many smart home departments now.

Unified networking is based on bus technology, which inevitably brings complicated wiring problems and increases the construction cost. Partial intelligence

The home system lacks software support, and the configuration process is very complicated, which can only be completed by professionals. Operational complex

Miscellaneous, mainly for the product design is not humanized, too many interfaces, confusion, or even no interface, which brings users

A lot of memory.

Verb (abbreviation of verb) The development prospect of the Internet of Things

Although the Internet of Things has yet to be perfected in the smart home industry, it does not affect our understanding of the Internet of Things.

Looking ahead, the development trend of the Internet of Things should have the following points:

1, wireless control continues to deepen: for example, in the application of smart home, the industry believes that WiFi will not be available in the future.

Wired network transmission technology and Zigbee wireless technology will be more widely used in the home. Users through Zigbee remote control,

You can inquire about the usage of household appliances connected to the home network and remotely control them by wireless. User is using

When, no longer limited to the traditional intelligent terminal equipment, home TV, computer, mobile phone and other display devices can be used as control.

Terminal. Therefore, adding wireless and remote control technology to smart home system will give full play to the functions of smart home.

Bring users a convenient life experience. We believe that in the future, the application of the Internet of Things will continue to deepen through the improvement of technology.

Line intelligent control technology to meet the needs of more consumers.

2. Strong network functions: networking has always been the main development trend of the Internet of Things. Through the internet, people

Children can effectively combine the video surveillance in the smart home system with the mobile phone, and send out an alarm signal once a thief enters the home.

It can be quickly transmitted to the community security center, regional alarm center and user's mobile phone through the network. All alarm centers and users

Video images can be retrieved immediately, ensuring effective monitoring of the thief's face at the first time and ensuring future investigation and evidence collection. the same

At that time, we can also use the intelligent transportation system to respond any related problems in traffic to the traffic police on duty in time, so as to

To improve efficiency.

3. The content of intelligent control is gradually expanding: the Internet of Things makes people's life experience more convenient through intelligent means.

Convenient and comfortable. In view of the defects of the Internet of Things in some applications at present, it is conceivable that it must be overcome in the future society.

Today's intelligence can't fully realize intelligence, which is too complicated.

Generally speaking, the Internet of Things is a new but very useful industry, which will play an important role in today's society and in the future.

Society will bring earth-shaking changes to people's lives. Although the Internet of Things has been applied in various fields, especially

It has developed well in the field of smart home, but we should also see some problems that appear at present.

Only by solving the shortcomings of the application of the Internet of Things in some fields can the Internet of Things play a better role.

Our service makes our life more convenient and comfortable.
