With the development of technology, especially the emergence of cloud computing and the Internet of Things, the concept of smart home frequently appears on all major media and enters the public eye. So what is smart home?
Smart Home connects various devices in the home (such as audio and video equipment, lighting systems, curtain control, air conditioning control, security systems, digital cinema systems, audio and video servers, video cabinet systems, network appliances, etc.) through IoT technology. Home appliances control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control and other functions and means. In China, the concept of smart home appeared in the 1990s, when only a few companies in Shenzhen began to engage in related businesses. Since then, smart homes have experienced germination, start-up and flood seasons in China, and have now begun to evolve. The next 5 to 10 years will be a period of rapid growth in the smart home industry, but it will also be the most unpredictable period. As residential households become the focus of competition in various industries, smart home as a platform for acceptance will become the first goal of all parties.
With the IT giant entering the smart home market, wireless smart homes, which are the backbone of smart homes, are also quietly emerging. Due to the humanized design of wireless smart homes and the integration of green and environmental features, smart homes are favored by people in the industry and their future. The market will grow geometrically. As the backbone of smart homes, wireless smart homes have emerged under the impetus of the Internet of Things, and have gradually grown. It is foreseeable that wireless will become the main force of smart home in the future. So what are the wireless technologies in smart homes?
ZigBee
ZigBee is one of the most popular wireless technologies in the smart home industry. ZigBee technology is a close-range, low-complexity, low-power, low-rate, low-cost two-way wireless communication technology. Compared with traditional wireless systems, data transmission security and low power and low transmission distance limit, ZigBee proposes fundamental The solution is to solve the security problem with AES 128-bit encryption technology, and use Ad-Hoc's Mesh network technology to eliminate the limitation of the transmission distance of low power itself. 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.
Infrared transmission
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.
WiFi
WiFi-based smart home products are the most common, because WiFi itself has been widely used. For the user, the smart home combination based on WiFi is the most trouble-free, and the purchase device can be directly connected to the network. Prior to the emergence of smart home items that were perceived and controlled, WiFi was mainly used for the transmission of large data streams (such as TV boxes and speakers) because of its fast transmission speed, but the disadvantages were higher cost and power consumption. In addition, since the WiFi smart home requires time-to-time online, the load of WiFi on the ordinary router in the smart home networking is relatively high. Generally speaking, the load of an ordinary household router is about 8 to 10 devices, and the stability will change afterwards. . Through the use of WiFi technology, it has successfully connected various devices and building intercoms of smart homes, providing a smarter, safer and more convenient smart home living space than traditional smart homes, optimizing people's lifestyles and bringing users A brand new home life.
Zwave
In addition, there is a wireless technology, Zwave, because its frequency band is non-civilian in China, so Zwave smart home is not common in China, and it is used more abroad. Zwave's data transmission rate is 9.6 kbps, and the effective coverage of the signal is 30 meters indoors (more than 100 meters outdoors). It is suitable for narrow bandwidth applications and has certain security and stability, but it is currently only used in the home. Automation. The main disadvantages are as follows: First, there are fewer nodes, the theoretical value is 256, and the actual value may be only about 150. It is the upper limit of the number of devices that can be accommodated. In fact, many manufacturers can accommodate 20 to 30 devices. Not bad; the second is the tree-like networking structure. Once the top of the branch is broken, all the devices at the lower end will not be able to communicate with the gateway. Third, there is no encryption method, the security is poor, and it is vulnerable to attack.
With the continuous development of technology, wireless technology is undergoing rapid changes. It is believed that in the near future, there will be a emergence of wireless technology that combines the advantages of all parties, and will bring revolutionary changes to the smart home industry. The future prospects of smart homes will also evolve with the improvement of their technical support means (such as wireless technology), and eventually become a new lifestyle that is convenient, efficient, fast, intelligent and low-cost.
