In recent years, the development of smart homes is indeed very fast. This kind of fast is not only reflected in the growth rate, but also reflects the change of our understanding of ideas. At the beginning of this year, smart home wireless communication technology can also make us talk about it, and the year has not finished, the cloud has become our talk about smart home intelligence. Earlier, we used to emphasize the advantages of a wireless communication technology. Today, a smart home without "cloud" may be "pseudo-intelligence."
In order to illustrate the importance of smart home wireless technology, many people in the industry called wireless technology instead of wired technology as "the smart home ushered in a second revolution." Indeed, the introduction of wireless technology has made smart homes free from the drawbacks of large and Flexible Cable technology, the need to drill holes in the wiring, complicated construction, fixed functions, relatively high cost, etc., and speed up the promotion and popularization, but in wireless technology. After becoming a mainstream technology, it has gradually become "plain", and it is difficult to support the further development of smart homes and the continuous breakthrough of intelligent functions.
In the smart home field, common wireless communication technologies include radio frequency (RF), IrDA infrared, WiFi, Bluetooth, Z-wave, ZigBee, and SmartRoom. Any comparison between these technologies, the correct conclusions are good or bad. The functions implemented are essentially the same, and the information exchange between the device and the device is realized. If the wireless communication technology is taken seriously, the reason may be that they are the "wires" that connect the "points" of the smart home system internal devices, thus forming a smart home "network." In other words, wireless communication technology is also the foundation of smart home networks. Without them, smart home devices cannot communicate.
However, it has to be acknowledged that wireless communication technology and wireline communication technology do the same thing, but the way of working differently, and with the popularity of wireless communication technology, the initial wireless connection advantage has been greatly weakened. In addition, the “gap†between various wireless technologies is gradually being eliminated. The incompatibility caused by the absolute “barriers†between technologies has begun to break through, and the impact of this situation is single technology. The advantages and disadvantages are merged and compensated. It is difficult to have a sense of “one big oneâ€, and wireless technology is naturally difficult to be an important reason for advanced equipment.
We can't ignore the impact of the smart home platform on wireless communication technology. The emergence of the platform has further reduced the status of wireless technology. At the beginning of June this year, at the Apple Worldwide Developers Conference (WWDC), Apple launched the smart home platform HomeKit. HomeKit is completely different from previous emphasis on technical standards, because Apple does not mention technical standards, but uses partnerships to enable it to control third-party smart home hardware, and third-party hardware adapts to Apple. Similarly, there is SmartThings, a smart home platform that was acquired by Samsung for $200 million. This platform allows products of different communication technologies to coexist without much emphasis on the advantages of any wireless technology.
Wireless technology is gradually becoming less competitive and becoming "tidy", but smart homes cannot stop there. Obviously, after the convenience, security, stability and compatibility of the network set up by wireless technology are becoming more and more mature, it is difficult for smart homes to rely on wireless technology, and new breakthroughs are needed. Cloud is definitely a good choice. .
In fact, for the compatibility issue between different wireless technology devices of smart homes, some people have proposed to use cloud services to solve them. The analyst believes that "cloud services can better connect devices in the home, but can be sorted in order", so that different modules of intelligent devices can not interfere with each other, while at the same time Can reach data sharing. Of course, the ability of the cloud in the field of smart homes not only solves the compatibility problem, but also serves as a new driving force to enhance the smart home intelligent function.
As we all know, the key problem that smart homes currently have is not stability, security or compatibility, but huge data. Tang Xiongyan, chief expert of China Unicom Network Technology Research Institute, once said, “In the era of big data, everyone is a contributor to data. It is estimated that by 2020, the average Chinese family will produce data equivalent to half of the national library’s information reserves. "The massive data comes from people's daily use of the Internet, such as search, shopping, social, etc., and the other is from Internet of Things devices, such as smart cameras, smart weight scales, air quality detectors and other smart home products." . If these data are not processed effectively, it will transform garbage and affect the smart effects of smart homes. how to solve this problem? The answer is the cloud.
Zhang Yaqin, president of Baidu, once said, "Cloud computing and big data are two sides of a coin. Cloud computing is the IT foundation of big data, and big data is a killer application of cloud computing. Cloud computing is the driving force for big data growth, and On the other hand, more and more data needs to be processed by cloud computing, so cloud computing and big data are complementary.†A similar point of view is related to the technical staff of Nanjing IOT, who believe that “cloud gives smart home devices unprecedented. The computing power and the growth ability can effectively analyze and memorize the data and information of the smart devices in the user's home in the first time, and apply the corresponding rules to the smart devices in turn to enhance the intelligent effect of the smart home."
It is worth mentioning that cloud technology that is targeted by many smart home manufacturers is not only a "hobby" of IoT devices and solution providers. Many Internet companies are also interested in Baidu, Tencent and Ali in China. More influential Internet companies such as Beijing Capital and 360 have developed the cloud to varying degrees. It is conceivable that the cloud will become one of the most critical technologies in the future.
Aerial bundled cable is a type of electrical cable that is used for overhead power distribution. It consists of several insulated conductors that are bundled together and covered by a protective sheath. The conductors are usually made of aluminum or copper and are insulated with cross-linked polyethylene or polyvinyl chloride .
ABC is commonly used in rural areas and in locations where underground cabling is not feasible or cost-effective. It is also used in urban areas for low voltage distribution and street lighting. ABC is designed to withstand extreme weather conditions, such as high winds, snow, and ice.
One of the main advantages of ABC is that it requires less maintenance than traditional overhead lines. The insulated conductors are less likely to come into contact with each other or with trees and other objects, reducing the risk of power outages and other issues.
ABC also offers improved safety compared to traditional overhead lines. The insulation on the conductors reduces the risk of electrical shock and fire, and the bundled design reduces the risk of accidental contact with the wires.
Overall, ABC is a reliable and cost-effective solution for overhead power distribution, particularly in areas where underground cabling is not feasible.
