Intelligent home through Internet of equipment (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital theater system, audio-visual server, video cabinet system, network home appliance, etc.) to provide Home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, heating control, infrared forwarding, and programmable timing control. Compared with ordinary homes, smart home not only has traditional residential features, bobistic, network communication, information home appliances, equipment automation, information interaction function, and even saving funds for various energy expenses.
First, home automation
Home Automation refers to the use of microprocessive electronic technology to integrate or control electronics products or systems in their home, such as lighting, coffee furnaces, computer equipment, security systems, heating and air-conditioning systems, video and audio systems. The home automation system is mainly based on a central microprocessorUnit, CPU to receive a message from related electronic electrical products (changes in external environmental factors, such as the light change of the sun, the elements of the West, etc.) The established program sends an appropriate information to other electronic appliances. The central microprocessor must control the electrical products in the home through many interfaces. These interfaces can be a keyboard, or a touch screen, buttons, computers, telephone, remote control, etc .; consumers can send signals to central microreating Machine, or receive signal from the central microprocessor.
Home automation is an important system of smart homes. When the smart house has just emerged, family automation even equivalent to smart home, today it is one of the core of smart home, but with network technology has a universal application of smart home, network Many product features of home appliances / information home appliances will be integrated into these new products, so that simple home automation products are increasing in system design, and their core status will be homewed by home network / home information system replace. It will play a role in a smart home as a part of the control network in a home network.
Second, the home network
First of all, you must separate this home network and pure “home local area network”, “Home Local LAN / Home Internal Network” name, it refers to the network system connected to the family, various peripherals, and the Internet system. It is just a part of the home network. The home network is a new technology that connects PC, home appliances, safety systems, lighting systems, and wide area networks (scales to neighbors, cells). The connection technologies currently used in home networks can be divided into two categories: “wired” and “wireless”. Wired solutions mainly include: twisted pair or coaxial cable connection, telephone line connection, power line connection, etc .; wireless solutions mainly include: infrared connection, radio connection, RF technology connection and PC-based wireless connection, etc.
Compared to traditional office networks, there are many home appliances and systems, such as home appliances, lighting systems, so corresponding technical standards are also intricate, which is also involved in too many well-known network manufacturers and home appliance manufacturers. We will introduce a variety of technical standards in a chapter of Smart Home Technology. According to observation, the development trend of home networks is integrated into other systems in smart homes.
Third, network home appliances
Network home appliances are new home appliances that use digital technology, network technology and intelligent control technology to use digital technology, network technology and intelligent control technology. Network home appliances can achieve interconnection to form an internal network, and this home network can be connected to external internet. It can be seen that the network home appliance technology includes two levels: first, the interconnection problem between home appliances, that is, the ability of different home appliances can be identified and work together. The second level is to solve the communication of the home appliance network and the external network, so that the home appliance network in the family is truly becoming an extension of the external network.
To achieve interconnection and information exchange between home appliances, you need to resolve: 1. Describe the product model of the work characteristics of home appliances, so that the exchange of data has a specific meaning; 2. Information transmission network media. In solving the difficulty of the network, selectable scenarios: power lines, wireless RF, twisted pair, coaxial cable, infrared, fiber. More feasible network appliances include network refrigerators, network air conditioners, network washing machines, network water heaters, network microwave, network cookware, etc. The future direction of online home appliances is also fully integrated into the home network.
Fourth, information appliance
Information home appliances should be a home appliance product, low price, simple operation, strong practical, and PC. Using computers, telecommunications and electronic technology and traditional home appliances (including white home appliances: refrigerator, washing machine, microwave, etc., and black home appliances: TV, video recorder, audio, VCD, DVD, etc.) are for digital and network technology. New home appliances designed more widely in the family life, information appliances include PC, set-top box, HPC, DVD, VCD, wireless data communication devices, video game devices, webTV, Internet telephones, etc., all can interact with network systems Home appliances can be called information appliances. Audio, video and communication devices are the main components of information appliances.
On the other hand, on the basis of traditional home appliances, integrating information technology into traditional home appliances, making it more powerful, more simple, convenient and practical, and creates higher quality living environment for family life. For example, analog TV developed into digital TV, VCD turns into DVD, refrigerator, washing machine, microwave, etc. will also become digital, networked, intelligent information appliances. The product intelligent solution to Keilin”s smart home is really this technical principle. Traditional equipment manufacturers only need to reserve interfaces on the product, to quickly complete the product”s intelligent upgrade by implanting WiFi or Zigbee modules, customizing App Software and Cloud services. This reduces the labor and funding costs of traditional enterprises to form their own R & D team, which also shortens the time efficiency of R & D intelligent products. At present, the program has been used by hundreds of well-known home appliance manufacturers at home and abroad, intelligent hardware enterprises, and have been rated as The intelligence application project in Zhejiang Industrial Field is promoted.
From a broad classification, information home appliances actually contain network home appliances, but if we define a narrow definition, we can do this simple category: Information appliances more refers to small households with embedded processors. (Individual) Information equipment, its basic feature is to connect with the network (mainly Internet), and some specific functions can be a complete set of products, or an auxiliary accessory. Network home appliances refers to a home appliance product with network operation. This home appliance can be understood that the upgrade of our original home appliances.
Information home appliances are composed of embedded processors, associated support hardware (such as display cards, storage media, IC cards, or credit cards), embedded operating systems, and software packets for application layers. Information home appliances decompose some of the features of PC, designed to be more applicable, more homeclad, so that the pace of ordinary residents” information age is more fast, is a LNTERNET with high performance, low price, easy operation characteristics tool. The emergence of information appliances will promote the rise of home network markets, while the development of home network markets has in turn to promote the popularity and deep application of information appliances.
Summary: The development of smart home is mainly based on light remote control, electrical remote control, and electric curtain control. With the development of the industry, more and more functions of intelligent control, the controlled object is expanded, and the linkage scenario requirements are more High, it continuously extends to the family security alarm, background music, visual intercom, access control fingerprint control, etc., it can be said that smart home can almost cover all traditional weak electricity industries, the market development prospects are seductive, so they are related to their industries The road brand does not agree with the intelligence to compete for smart home business, and the market is gradually incorporated into the Spring and Autumn Heart.
