Home security system appeared in the domestic market after the new century, and its development speed was relatively slow at first. In recent years, with the development of mobile technology, especially the popularity of high-speed wireless networks such as WIFI and 3G, the home security market has ushered in real development. At present, the market scale has exceeded 2 billion yuan. Although the overall scale is low, it is the fastest growing market in the security field, and has attracted a series of well-known enterprises including Lenovo and Haier to join it.

First, the basic concept of smart home
Smart home is a residential-based platform, which integrates facilities related to home life by using integrated wiring technology, network communication technology, safety prevention technology, automatic control technology and audio-visual technology, builds an efficient residential facilities and family schedule affairs management system, enhances the safety, convenience, comfort and artistry of home, and realizes an environmentally-friendly and energy-saving living environment.
Smart home integration is to integrate devices related to home life by using integrated wiring technology, network communication technology, security technology, automatic control technology and audio and video technology. Because of the different technical standards and protocols adopted by smart homes, most smart home systems use integrated wiring, but a few systems may not use integrated wiring technology, such as power carrier. In either case, there must be corresponding network communication technology to complete the required signal transmission task, so network communication technology is one of the key technologies in smart home integration. Security technology is an essential technology in smart home system, which is widely used in residential and indoor visual intercom, home monitoring, home burglar alarm, family-related community cards and other fields. Automatic control technology is an essential technology in smart home system, which is widely used in smart home control center and automatic control module of home equipment, and plays a very important role in scientific management of home energy and schedule management of home equipment. Audio and video technology is an important technology to realize the comfort and artistry of home environment, which is embodied in centralized distribution of audio and video, background music, home theater and so on.
Also known as smart house. Generally speaking, it is a networked smart home control system integrating automation control system, computer network system and network communication technology. Smart home will provide users with more convenient means to manage household equipment, such as controlling household equipment through home touch screen, wireless remote control, telephone, internet or voice recognition, and performing scene operation to make multiple devices form linkage; On the other hand, various devices in smart home can communicate with each other and operate interactively according to different states, without user's command, thus bringing maximum efficiency, convenience, comfort and safety to users.
Smart home is the embodiment of the Internet of Things under the influence of the Internet of Things. Smart home connects all kinds of devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, network appliances and three-meter cc, etc. ) Through the Internet of Things technology, it provides various functions and means such as home appliance control, lighting control, curtain control, telephone remote control, indoor and outdoor remote control, burglar alarm, environmental monitoring, HVAC control, infrared forwarding, programmable timing control, etc. Compared with ordinary homes, smart homes not only have traditional living functions, but also have functions such as building, network communication, information appliances and equipment automation. They have an efficient, comfortable, safe, convenient and environmentally-friendly living environment that integrates system, structure, service and management, provide all-round information interaction functions, help families keep smooth information communication with the outside world, optimize people's lifestyles, help people arrange their time effectively, enhance the safety of home life, and even provide a variety of services.
Second, the introduction of smart home system
The main subsystems of smart home system include: home wiring system, home network system, smart home (central) control management system, home lighting control system, home security system, background music system (such as TVC flat-panel audio), home theater and IOT smart home control system, multimedia system and home environment control system. Among them, smart home (central) control and management system, home lighting control system and home security system are necessary systems, and home wiring system, home network system, background music system, home theater and multimedia system and home environment control system are optional systems.
In the identification of smart home system products, the smart home (smart home system products) produced by the manufacturer must belong to the essential system and can realize the main functions of smart home before it can be called smart home. Therefore, smart home (central) control management system, home lighting control system and home security system can be directly called smart home (smart home system products). However, none of the optional systems can be directly called smart home, and only the combination of smart home and specific systems, such as background music system, can be used, which is called smart home background music. It is a misleading behavior to call optional system products smart home directly.
In the identification of smart home environment, only a smart home with all necessary systems and at least one or more optional systems can be called smart home.
According to the classification of Intelligent Committee of China Interior Decoration Association on April 5, 20 12, smart home system products are divided into 20 categories: control host (centralized controller); Intelligent lighting system; Electrical control system; Family background music; Home theater system; Intercom system; Video surveillance; Burglar alarm; Electric lock access control; Intelligent sunshade (electric curtain); HVAC system; Solar energy and energy-saving equipment; Automatic meter reading; Smart home software; Home wiring system; Home network; Kitchen and bathroom TV system; Exercise and health monitoring; Automatic watering of flowers and plants; Pet care and animal control.
Combined with the application of security products and technologies, smart home mainly has the following functions:
(A) alarm and linkage function
Install door magnet and window magnet to prevent illegal entry. The management system can get the signal through the alarm controller installed in the residents' room and quickly receive the alarm for processing. Alarm linkage control can automatically turn on indoor lighting and start the alarm when an alarm occurs indoors, and the system sends out alarm information at the same time.
(2) Emergency help function
The indoor alarm controller has the function of emergency call, and the management system can respond to and rescue residents' emergency help signals.
(3) Alarm management display function
The mode of leaving home is burglar alarm to prevent illegal intrusion. The management system can receive alarm signals in real time, automatically display alarm households and alarm types, and automatically archive system information.
(4) preset alarm function
The intelligent security system can preset alarm calls.
(5) Set/cancel linkage control
In home defense mode, the security system can cut off the power supply of some household appliances. In the home disarming mode, some lights are automatically turned on, and the door magnetism and window magnetism are offline. Indoor smoke detector and kitchen combustible gas detector are still in alarm mode.
(6) Control and handling after alarm
When there are illegal intruders or gas leaks at home, the system will automatically make phone calls, send SMS, MMS, capture pictures and send them to the designated users' mobile phones by email! After receiving the telephone message, the user can check the home monitoring screen with the mobile phone computer at the first time, and control the home appliance setting, defense, disarmament and other operations.
Third, the main functions of smart home
Intelligent video surveillance
With the upgrading of people's living environment, people pay more and more attention to their personal safety and property safety, and put forward higher requirements for the safety of people, families and residential quarters; At the same time, with the rapid development of economy and the rapid increase of urban floating population, new problems have been added to urban social security. In order to ensure the safety of the community and prevent theft and robbery, we must have our own security system. The security mode of civil air defense is difficult to meet our requirements, and intelligent security has become the current development trend.
Video surveillance systems have been widely used in banks, shopping malls, stations, traffic intersections and other public places, but the actual monitoring tasks still need to be completed manually, and the existing video surveillance systems usually only record video images, and the information provided is unexplained video images, which can only be used as evidence afterwards, without giving full play to the real-time and initiative of monitoring. In order to analyze, track and identify the monitored objects in real time, prompt and report when abnormal events occur, and provide support for government departments and security fields to make timely decisions and take correct actions, the "intelligence" of video surveillance is particularly important.
Advantages:
1. security: the security system can detect stranger intrusion, gas leakage, fire, etc. And notify the owner in time;
2. Simplicity: the operation is very simple, and it can be unfolded or released by remote control or door controller.
3. Practicality: The video surveillance system relies on the camera installed outdoors, which can effectively prevent the thief from further actions, and can also obtain evidence afterwards to provide favorable evidence for the police.
(2) Intelligent video * * *
Video sharing system is to install digital TV set-top boxes, DVD players, video recorders, satellite receivers and other video equipment in hidden places. The system can make the TV in living room, dining room, bedroom and other rooms enjoy the family audio-visual library, and you can choose your favorite audio source to watch through the remote control. In this way, the TV can enjoy audio-visual equipment, and there is no need to buy equipment and wiring, which saves money and money.
Advantages:
1, simple: simple wiring, one line can transmit various video signals, and the operation is more convenient.
2. Practicality: No matter where the host is, a remote controller can control all video hosts.
3, safety: weak current wiring, network cable to transmit signals, never out of date, even if the future upgrade or network cable.
(3) Visual intercom system
Visual intercom products are relatively mature, and mature cases can be seen everywhere. There are large-scale networked intercom systems and independent intercom systems, such as those used in villas, which are divided into one, two and three. The general functions are talking, viewing, intercom and other functions, but through the integration department of Pinqiju, many products of different platforms are unified, which enhances the advantages of the control part of the whole system and allows the indoor host to control the lights and appliances at home.
Fourth, the development of smart home.
As a new industry, smart home is currently at the critical point of the introduction period and growth period, and the concept of market consumption has not yet been formed. However, with the further implementation of the popularity of smart home market and the cultivation of consumer habits, the consumption potential of smart home market is bound to be huge, and the industry prospect is bright. Because of this, domestic excellent smart home manufacturers pay more and more attention to the research on the industry market, especially the in-depth research on the development environment of enterprises and the changes of customer demand trends. A large number of domestic excellent smart home brands have risen rapidly and gradually become the leader in the smart home industry! Smart home has experienced nearly 12 years of development in China, and it has gone through a difficult process from people's initial dreams to today's real life.
The development of smart home in China has gone through four stages, namely, budding stage/smart community stage, pioneering stage, wandering stage and integration and evolution stage.
(1) budding stage/smart community stage (1994-1999)
This is the first development stage of smart home in China. The whole industry is still in a stage of concept familiarity and product cognition. At this time, there is no professional smart home manufacturer. There are only one or two companies in Shenzhen that sell X- 10 smart homes in the United States, and their products are mostly sold to European and American users living in China.
(2) Initial stage (2000 -2005)
More than 50 smart home R&D and production enterprises have been established in China, mainly distributed in Shenzhen, Shanghai, Tianjin, Beijing, Hangzhou and Xiamen. The marketing and technical training system of smart home has been gradually improved. At this stage, foreign smart home products have basically not entered the domestic market.
(3) Wandering period (2006-20 10)
After 2005, due to the barbaric growth and vicious competition of smart home enterprises in the previous stage, it has brought great negative effects to the smart home industry, including exaggerating the functions of smart home but failing to achieve this effect. Manufacturers only pay attention to the development of agents and ignore the training and support for agents, which leads to the difficulties of agents' operation and the high rate of user complaints due to unstable products. Industry users and media began to question the actual effect of smart home, and became cautious from the initial advocacy. In recent years, the growth of market sales slowed down, and even sales in some areas declined. From 2005 to 2007, about 20 smart home manufacturers withdrew from this market, and many agents from all over the world graduated and changed careers. Many smart home companies that have persisted have also experienced the pain of layoffs in recent years. During this period, foreign smart home brands secretly entered the China market. At present, the major foreign smart home brands active in the market all entered the China market during this period, such as Legrand, Honeywell, Schneider and Control4.
(IV) Evolution period of integration (20 1 1-2020)
Since 20 1 1, the market has clearly seen the growth momentum, and the big industry background is that real estate is regulated. The growth of smart home shows that the smart home industry has entered an inflection point, from the wandering period to a new round of integration and evolution.
In the next three to five years, on the one hand, smart home has entered a relatively rapid development stage, on the other hand, agreements and technical standards have also begun to actively communicate and integrate, and the phenomenon of industry mergers and acquisitions has begun to come out and even become the mainstream.
In the next five to ten years, the smart home industry will develop very rapidly, but it is also the most unpredictable period. With the residential family becoming the focus market for various industries, smart home as a platform has become the first goal for all parties. We can analyze who will win in the end, but the final result may not be known until then. However, no matter how it develops, smart home enterprises with annual sales of tens of billions of yuan will be born in China at this stage.
Verb (abbreviation of verb) The development trend of smart home
A series of policies related to smart home, such as Special Fund for the Development of Internet of Things, General Rules for Intelligent Technology of Smart Home Appliances, Annual Blue Book for the Development of Internet of Things Industry in China, Twelfth Five-Year Plan for Broadband Network Infrastructure, and Design Standard for Smart Buildings, have been issued one after another, effectively implementing the smart home industry.
In recent years, in the process of step-by-step development, smart home has gradually formed an industry trend, and there are more and more available products close to the real needs. Enterprises have accumulated a lot of experience in these areas. How to build a smart home system with high efficiency and low cost has become a hot issue in current society. The development of a series of standardization work has provided an open standardization platform for the development of smart home in China and pointed out the correct development direction for the research field of smart home.
The grand occasion of Beijing Security Exhibition 20 12 Smart Home Exhibition Hall is still fresh in people's memory. The most obvious feeling is that smart home has gradually changed from concept realization to user experience. Most of the previous smart products were based on home appliance control, lighting control and curtain control. After several years of technological development, especially the rapid rise of the Internet of Things and cloud computing, it has brought a new look to the smart home industry, and the definition of smart home has become broader. Smart home is no longer limited to video surveillance, burglar alarm, intelligent control and other common security. Through the application of the Internet of Things and cloud computing combined with the whole system platform, the information of food, clothing, housing and transportation will be implanted into the smart home system, which will cover all aspects of people's lives, including life and health, daily services, etc., and has extended from the pure security level to higher demand, creating a brand-new smart home system. Smart home enterprises are gradually transitioning from a separate product line to a comprehensive product system and overall solution.
In the field of smart home segmentation, smart home appliances, smart lighting, building intercom, home control, anti-theft alarm, etc. Their performance is also remarkable. Several giants, such as Haier, Changhong, Hisense and other groups, constantly introduce their own smart new products, especially the smart TV sector, which is mixed with concepts such as 3D and HD.
In addition, the vigorous development of smart terminals, the rise of Android system and the madness of Apple products have made electronic products such as smart phones and tablet computers quickly integrate into people's lives, and also brought about the rapid development of family control. Schneider Electric recently vigorously promoted smart home wireless lighting control system, making the field of intelligent lighting control more turbulent.
According to the analysis of industry veterans, the Internet of Things will activate 500 billion markets. "Internet of Things" and cloud computing projects have been launched in various places, bringing unlimited expansion space to smart homes. Chinese and foreign smart home enterprises strive to create "smart home" products, enhance their competitiveness, and gradually gain consumer awareness. China local security companies, home appliance companies, operators, IT communication companies, etc. Also participating in the production and research of smart home collectively, the most obvious is the rise of cloud tv focusing on front-end display. Using cloud computing, cloud storage and other technologies to upgrade existing intelligent cloud devices has many application advantages, such as mass storage, remote control, software update, unlimited content expansion and so on, which has been widely affirmed by consumers.
Analysis of Four Major Planning of Smart Home
Home automation
Home automation refers to the use of microprocessor electronic technology to integrate or control home electronic products or systems, such as lighting, coffee stoves, computer equipment, security systems, heating and cooling systems, video and audio systems. Home automation system mainly uses central processing unit (CPU) to receive information from related electronic and electrical products (changes in external environmental factors, such as changes in light caused by rising or setting of the sun, etc.). ), and then send appropriate information to other electronic and electrical products through established procedures. The central microprocessor must control household appliances through many interfaces, which can be keyboards, touch screens, buttons, computers, telephones, remote controllers and so on. Consumers can send signals to or receive signals from the central microprocessor.
Home automation is an important system of smart home. When smart home first appeared, home automation was even equivalent to smart home. Today, it is still one of the cores of smart home. However, with the wide application of network technology and the maturity of network appliances/information appliances, many product functions of home automation will be integrated into these new products, so that simple home automation products are less and less in system design, and their core position will be replaced by quilt home network/home information system. It will play a role in smart home as the control network part of home network.
Home network
First of all, this home network should be separated from the pure "home LAN". Home LAN refers to the network system that connects the PC, various peripherals and the Internet in the home, and it is only a part of the home network. Home network is a new technology to connect PC, home appliances, security system, lighting system and wide area network within the family (which can be extended to neighbors and communities). Home network has added many products and systems for home applications, such as home appliances, lighting systems, home theaters, music and so on. The development trend of home network is to integrate other systems in smart home, and finally realize "enjoying and perfecting smart life".
(3) Network household appliances
Network home appliance is a new type of home appliance designed and improved by using digital technology, network technology and intelligent control technology. Network home appliances can be combined into a home internal network by using the Internet of Things technology, and this home network can be connected with the external Internet. At present, the feasible network home appliances include network refrigerator, network air conditioner, network washing machine, network water heater, network microwave oven, network cooker and so on. The future direction of network home appliances is also fully integrated into the home network.
Information home appliance should be a kind of home appliance with low price, simple operation, strong practicability and main functions of PC. Innovative products that combine computer, telecommunications and electronic technologies with traditional household appliances (including refrigerators, washing machines, microwave ovens, electric ovens, bread makers, coffee makers, televisions, video recorders, home theaters, DVDs, etc.). ) is a new type of household appliance designed for digital and network technology to take root in family life more deeply. Information devices, especially small household (personal) information devices with embedded processors, can be described in more detail. Its basic feature is that it is connected with the Internet and has some specific functions. It can also be a home appliance product with network operation function after upgrading ordinary home appliances.
(d) Digital visual intercom system
Using intelligent digital visual intercom security system, visitors can call the indoor smart home terminal through the community/unit/door machine, which can realize video calling, remote unlocking, leaving messages, taking photos and other functions.
The indoor smart home terminal and the door machine of the community/unit can call the community management center machine, which can realize the functions of video calling and remote unlocking.
Two-way visual video call can be realized between indoor smart home terminals.
