Comprehensive Discussion on Internet of Things Knowledge

definition

The "Internet of Things Concept" is a network concept based on the "Internet Concept" that extends and expands its user end to any item and item for information exchange and communication. Its definition is: through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing equipment, according to the agreed agreement, any item is connected to the Internet for information exchange and communication to achieve intelligence A network concept of intelligent identification, positioning, tracking, monitoring and management.

 History

  

   The concept of the Internet of Things was proposed in China as early as 1999. However, at that time, it was not called the "Internet of Things" but the sensor network. The Chinese Academy of Sciences started the research and development of the sensor network as early as 1999. Compared with other countries, my country's technological research and development level is in the forefront of the world, with co-development advantages and significant influence.


   On November 27, 2005, at the Information Society Summit held in Tunisia, the International Telecommunication Union (ITU) released the "ITU Internet Report 2005: Internet of Things", which officially proposed the concept of the Internet of Things.


   On August 24, Wang Jianzhou, President of China Mobile, also mentioned the concept of the Internet of Things in a public speech in Taiwan.


   Zhu Hongren, chief engineer of the Ministry of Industry and Information Technology, said at the 2009 Summer Report on China’s Industrial Operations that the Internet of Things is a new concept, and so far there has not been a conventional and recognized concept. He said that in general, the "Internet of Things" refers to a new technology that connects various sensors with the existing "Internet".


   The Internet of Things is based on the computer Internet, using RFID, wireless data communication and other technologies to construct an "Internet of Things" covering everything in the world. In this network, items (commodities) can "communicate" with each other without human intervention. Its essence is to use radio frequency automatic identification (RFID) technology to realize automatic identification of items (commodities) and interconnection and sharing of information through the computer Internet.


   The advent of the concept of the Internet of Things broke the previous traditional thinking. The idea in the past has always been to separate physical infrastructure from IT infrastructure, on the one hand, airports, highways, and buildings, on the other hand, data centers, personal computers, broadband, etc. In the Internet of Things era, reinforced concrete, cables, chips, and broadband will be integrated into a unified infrastructure. In this sense, infrastructure is more like a new earth. Therefore, some people in the industry believe that both the Internet of Things and the smart grid are organic components of the smart earth.


   However, there are also opinions that the possibility of the rapid spread of the Internet of Things is difficult to judge lightly. After all, RFID has long been well-known in the market, but the regular reports of related listed companies with RFID business such as Newland show that the high growth of performance has not yet appeared. Therefore, there are big differences in the popularity of the Internet of Things. But what is certain is that in the context of the country's efforts to promote the integration of industrialization and informatization, the Internet of Things will be a more realistic breakthrough in the informatization process of industry and more industries. Moreover, RFID technology has some closed-loop applications in multiple fields and industries. In these first successful cases, item information has been automatically collected and online, and management efficiency has been greatly improved. Some of the dreams of the Internet of Things have been partially realized. Therefore, the embryonic form of the Internet of Things is just like the early form of the Internet, the local area network. Although it plays a limited role, it shows that the great prospects cannot be questioned.


   The smart home introduced in recent years is actually to control the home appliances through the network. It is conceivable that the Internet of Things has developed to a certain stage, and the electrical appliances in the home can be connected to the external network, and the signals of the electrical appliances can be transmitted through sensors. The manufacturer can know the usage of electrical appliances in your home in the factory, and perhaps know the malfunction of your electrical appliances before you. One day, a maintenance worker came to tell you that there was a problem with the air conditioner in your home, and you were surprised to not believe it.


The development of the Internet of Things will inevitably drive the development of sensors. When sensors develop to a certain extent, Transformers will really appear in front of us.

 

   The relationship between the Internet of Things, the concept of the Internet of Things and the Internet

  

   The relationship between any thing and the concept that the thing forms in people’s minds is an interdependent relationship. The concept of the thing is a reflection of the essential attributes of the thing in people's minds. The Internet of Things is also a thing. Therefore, the relationship between the Internet of Things and the concept of the Internet of Things is also an interdependent relationship. The concept of the Internet of Things has left the Internet of Things. The concept of the Internet of Things is a tree without roots and water without a source. The Internet of Things will inevitably form a corresponding concept of the Internet of Things in people’s minds. There will not be: only the Internet of Things, but no The concept of the Internet of Things emerges. This is the dialectical relationship between the Internet of Things and the concepts of the Internet of Things. Of course, in scientific practice, the scientific concepts formed in people’s minds are different from the concepts of daily life initially formed by people in the pre-scientific thinking period. The scientific concepts can also be used as a representation of a certain stage of understanding. Knowledge and scientific research results and summaries exist. The concept of the Internet of Things is also a scientific concept. Therefore, it can also exist as the result and summary of scientific knowledge and scientific research at a certain stage of understanding. As mentioned in the previous definition, the concept of the Internet of Things is a network concept that extends and extends its user end to any item and any item based on the concept of the Internet for information exchange and communication. It is also the result and summary of Internet knowledge and research.

 

   IoT concept stocks

  

Recently, in China, a new concept—the concept of the Internet of Things has been heated up. For a while, the “Internet of Things concept” is flying all over the sky. It seems that the era of the Internet of Things is about to come! In the A-share market, all stocks that are connected with the “Internet of Things concept”, Called the "Internet of Things concept stocks", they have soared recently. The "Internet of Things concept" has recently become a hot topic in the A-share market. So, what is the "Internet of Things concept stocks"? The so-called "Internet of Things concept stocks" are stocks with the concept of Internet of Things.


  The leading stocks of IoT concept stocks mainly include:


  1. Yuanwanggu (002161): The company is a leading UHF radio frequency identification (RFID) stock. The company is the only domestic listed company with RFID business as its main business, specializing in UHF RFID research and development. In addition to its business covering the entire railway radio frequency identification industry chain, it has also achieved initial results in other UHF RFID fields such as tobacco logistics and military applications. It now has 5 series of more than 60 products. In the industry chain of the Internet of Things, the company is one of the companies engaged in the research and development of RFID technology.


 2. Newland (000997): The company is one of the few companies in the world that has the core technology of QR codes. It has designed and developed the world’s first handheld QR code reading product, and is the first to successfully develop a product with independent intellectual property rights in China.
