2014 is the first year of smart home, but at present, 85% of people still do not know the concept of smart home and which device functions they should include. Now the technology is also in its infancy, and there is no clear and unified standard, making consumers dissatisfied with the current product.

Smart home products involve a wide range of industrial chains, including life and entertainment, security and health care applications. It can be divided into: convenient and energy-saving human home life products, networking system between products, human-computer interaction controlled by mobile phone to voice control, manufacturers launch supply chain platform to promote personalized and precision marketing services.

At present, it is still in the control mode of "mobile phone + ZIGBEE / RF / WIFI", but the smart home system has obvious advantages. The existing smart speakers, routers, service robots and other manufacturers are transforming into intelligent control center.

At present, smart home is mainly used in the high-end market: villas, smart community, the fastest growing business is smart hotel and office, and the development of ordinary home furnishing is slow. At present, the front-end market is still dominated by the mode of "manufacturers —— agents (real estate providers or system providers) —— consumers", accounting for 80% of the sales market.

According to statistics, the proportion of smart buildings in the United States accounts for 70% of the new buildings, 60% in Japan, and only 30% in China, but the market size grows by 30% every year.

A complete smart home system has basic functions: intelligent lighting control, electrical control, security control. There are scenes, kitchen, video system, virtual network, remote (timing remote control) control and other requirements.

Intelligent lighting control

Intelligent light control is based on the power line network, using power line carrier technology and power line information transmission X10 protocol, realize the remote control, centralized control, wireless remote control, computer control, timing control, network control and a variety of control mode, and provide light, dimming, brightness memory, scene memory such as intelligent operation and management. The intelligent lighting control function is set through the software, which can be realized through the software: switch, dimming, local control, multi-point control, remote control, regional control, etc. When used, you can switch scenes simply by touch operation.

Intelligent lighting control can be very convenient and theater, TV studio in other related control and management system (such as large studio stage lighting control system, multimedia internal communication system, security system, BA system, fire control system, etc.) platform extension and connection, realize "more network, resource sharing" management mode.

Intelligent electrical control

Traditional household appliances have air conditioners, refrigerators, vacuum cleaners, rice cookers, washing machines, etc., while new household appliances have induction cooker, disinfection cupboard, steaming and stewing pot, etc. Whether the new home appliances or the traditional home appliances, the overall technology is constantly improving. The key to the progress of household appliances lies in the use of advanced control technology, so that household appliances from a mechanical appliance into a kind of intelligent equipment, intelligent household appliances reflect the latest technology of household appliances. The degree of intelligent household appliances is different, and the degree of intelligence of the same kind of products is also very different, which can be divided into single intelligence and multiple intelligence. Single-item smart home appliances have only one function to simulate human intelligence. For example, in a fuzzy rice cooker, detecting the amount of rice and conducting corresponding control is a process of simulating human intelligence. In rice cookers, it is impossible to use a weight sensor to detect the amount of rice, which is not allowed by environmental overheating. Using the thinking process of people with a long time of time can realize the detection of food capacity, and take different control process according to the different food capacity. This kind of rice cooker is a kind of rice cooker with single item intelligence, which uses fuzzy reasoning to detect the amount of food, and also uses fuzzy control reasoning to control the whole process. A number of smart home appliances in a number of smart home appliances, there are manySpecies to simulate the functions of human intelligence. Multi-functional fuzzy rice cooker has a variety of functions to simulate human intelligence. LG Electronics, for example, has released high-end smart home appliances equipped with revolutionary information services in South Korea. HomeChatTM Works on two popular mobile social apps, NLP and LINE, which have more than 300 million users. With this technology, users can interact with LGs latest home appliances, control, monitor and share their usage through mobile phones

HomeChatTM explains what real intelligence is. LGs line of high-end smart appliances includes a refrigerator with a camera, a washing machine that allows users to start or download laundry programs through HomeChatTM technology, and a frequency microwave oven that supports NFC connectivity and WiFi connectivity.

Intelligent security control

The main connotation of intelligent security technology is the information of its related content and services, the transmission and storage of images, data storage and processing, and so on. In terms of intelligent security, a complete intelligent security system mainly includes access control, alarm and monitoring three parts. From the product point of view: it should have anti-theft alarm system, video monitoring alarm system, entrance and exit control alarm system, security personnel patrol alarm system, GPS vehicle alarm management system and 110 alarm network transmission system and so on. These subsystems can be set up separately, operated independently, monitored centrally by the central control room, and can be integrated with other integrated systems.

1. Anti-theft alarm system

The anti-theft alarm system is divided into perimeter defense, defense in the building area, defense in the open area of the unit enterprise, defense of physical equipment in the unit enterprise and so on.

The front end of the system is all kinds of alarm sensors or detectors; the terminal of the system is display / control / communication equipment, which can use independent alarm controller or alarm center console. No matter what way of control is adopted, real-time, reliable and correct review and alarm must be conducted for the illegal invasion in the fortified area. Leak alarm is absolutely not allowed to occur, and the false alarm should be reduced to an acceptable limit. Considering that the personnel on duty are vulnerable to the threat of force and robbery of the perpetrator, the system should set up the emergency alarm button and have an interface connected with the 110 alarm center.

2. Video surveillance alarm system 

The video surveillance alarm system is routinely used in the major public places and important parts of the building for real-time monitoring, video recording and image review during the alarm. The front end of the video surveillance alarm system is various cameras, video detection alarms and related auxiliary equipment; the terminal equipment of the system is display / recording / control equipment, with independent video monitoring center console or monitoring alarm center console. The video surveillance alarm system for security prevention should be linked with the anti-theft alarm system and the entrance and exit control system, and should be centrally managed and monitored by the central control room. In the independently running video surveillance alarm system, the screen display can be programmed, automatically or manually switched. The screen must have the number, address, time, date and other information of the camera, and the scene screen can be automatically switched to the designated monitor. The important monitoring screen should be recorded for a long time. Such systems shall have emergency alarm button and communication interface with 110 alarm center networking.3 Entry and exit control alarm system.

Entrance and exit control alarm system is an automatic system that adopts modern electronic information technology to release, release, reject, record, and alarm at the entrance and exit of buildings.

This operating system usually consists of three parts: entry and exit target identification system, entry and exit information management system, and entrance and exit control actuator. The front-end equipment of the system are all kinds of entrance and exit target identification devices and door lock opening and closing actuator; the transmission mode adopts special line or network transmission; the terminal equipment of the system is display / control / communication equipment, generally using independent access control controller or centralized monitoring of each door controller through computer network.

The entrance and exit control alarm system should be routinely linked with the anti-theft alarm system, closed-circuit video monitoring alarm system and fire control system to effectively realize safety prevention. The entrance and exit target recognition system can be divided into recognition of people and recognition of objects. Taking human identification as an example, it can be divided into two categories: biometric system and coding standard identification system.

environmental monitoring system

The greatest value of a smart home is its health, And the health protection lies in the environmental monitoring systems, Our perception can only pass on to "Im hot" or "Im cold," Then autonomously drive the appliances in the home to work, But can not really understand the environment at home (such as: formaldehyde, PM2.5, C02 data, etc.) they are colorless and tasteless, If the newly decorated house indoor formaldehyde is basically exceed the standard, Even with the environmentally friendly materials used, The incubation period of formaldehyde is 3-15 years, So we have to know the environmental index of our home in real time through intelligent environmental monitoring, Independent detection of indoor and outdoor air comparison, To improve the environmental conditions independently, To truly improve the quality of life of users.

Epilogue

A complete intelligent video surveillance security prevention system, the conventional also includes the security personnel patrol alarm system, the visitor alarm system and other intelligent security prevention system. The patrol alarm system through the pre-prepared security patrol software, the application card reader to monitor the movement status of the security personnel patrol (whether on time, comply with the order, etc.), make records, and timely alarm the unexpected situation. The visitor alarm system is to enable the personnel living in the building to talk to visitors in a two-way or visual call. The personnel living in the building can open or close the entrance door or unit door in the building, and alarm the security center in time when the accident occurs. Other intelligent security prevention systems are set up according to the needs of special security prevention management. For example, GPS vehicle alarm management system and 110 alarm network transmission system, access control, monitoring, traffic signal indication and parking charge shall be integrated; Besides, the safety prevention system of important warehouse must provide effective entrance and exit control, anti-theft, monitoring control and management for the important warehouse in the building.
