In recent years, the market demand for terminal products has been continuously released and the market application field has continued to expand, which has promoted the rapid promotion of intelligent control in the fields of home appliances, digital, electric power, and Internet of Things. The upgrading of home appliances will bring continuous growth space for smart controllers for home appliances in the future. In 2012, due to the unclear global economic situation, the development of the scale of intelligent control products has been affected to some extent. However, the comprehensive trend of the domestic and international markets will not be reversed. Under the theme of today's economic restructuring and consumption upgrading, China's intelligent control industry has a huge demand for end market demand.
Smart city drives smart home development
The construction of smart cities is the focus of current national urban construction. China's many intelligent industry research achievements and products in the construction of smart cities have been at the forefront of the world. Alarm and video linkage, intelligent video analysis, data mining, intelligent retrieval, visual guidance based on spatial visualization technology, massive video data scheduling and management, cloud computing, big data management and other intelligent technologies are getting more and more in the field of security video surveillance More applications.
Thanks to the attention of smart cities, smart homes are also in full swing. With the rise of the concept of Internet of Things, cities are competing to build smart cities and safe cities. Using the Internet of Things and sensor networks to improve the level of urbanization management, to achieve accurate service to the people, benefit the people is the highest pursuit of all levels of government. These aspects involve the city's smart home, intelligent transportation, intelligent buildings, smart medical, food and drug management, ticket management, home care, elderly health and digital life. On the basis of building a public domain service framework, the government's best service path to enter the family is to continuously improve the living environment and quality of the people through the construction of smart communities and smart homes.
Smart home main wireless technology
As the backbone of smart homes, wireless smart homes have emerged under the impetus of the Internet of Things, and have gradually grown. At present, home equipment interconnection communication is mainly based on wireless connection, among which Wi-Fi based on 802.11 protocol is the most common, in addition, Bluetooth, NFC (RFID), Zigbee, Z-wave, UWB, IrDA, etc. are also in different scenarios. There are applications.
ZigBee is one of the most popular wireless technologies in the smart home industry . ZigBee technology is a short-distance, low-complexity, low-power, low-rate, low-cost two-way wireless communication technology. Compared with traditional wireless systems, which have data transmission security and low power and low transmission distance, ZigBee proposes a fundamental The solution is to solve the security problem with AES128-bit encryption technology, and use Ad-Hoc's Mesh network technology to eliminate the limitation of low power consumption transmission distance. ZigBee wireless technology is gradually matured, cost costs are gradually reduced, and smart home controllers and ZigBee wireless technologies are gradually being integrated. Ultimately, wireless smart home control will lead the market to a wider range of applications, including business and even military applications. The development of smart homes will undergo a change and a fascinating vision due to the wireless technology revolution.
Bluetooth is also a more common wireless connection technology. Bluetooth supports short-range communication, usually within 10m. Smart home devices enable simple communication between devices via Bluetooth, as well as simplify communication between devices and the Internet. Bluetooth uses a decentralized network structure and fast frequency hopping and short packet technology to support point-to-point and point-to-multipoint communication with a data rate of 1 Mbps.
Infrared transmission is currently the most widely used communication and remote control method. Because infrared remote control device has the characteristics of small size, low power consumption, strong function, low cost, mature technology, good stability, strong privacy and low cost. Widely used in smart home control systems . Although it has some technical bottlenecks and defects, such as short transmission distance and small communication angle, other wireless communication technologies have not yet reached perfect level. Therefore, in the future, infrared transmission technology will still be controlled in smart home. The system occupies a place.
