The "Internet of things", first mentioned in the 1999, through the radio frequency identification (RFID) (RFID+ Internet), infrared sensors, GPS, laser scanners, gas sensors and other sensing devices, according to the agreement, any items and Internet connection, information exchange and communication, in order to achieve a network of intelligent identification, positioning, tracking, monitoring and management. In short, the Internet of things is the Internet connected with things".
"Internet of things" concept came out, breaking the traditional thinking before. The idea has been to separate the physical infrastructure from the IT infrastructure: on the one hand, airports, roads, buildings, on the other hand data centers, personal computers, broadband, and so on. In the "Internet of things" era, reinforced concrete, cable with the chip, broadband integration into a unified infrastructure, in this sense, the infrastructure is more like a new site of the earth, the world really works on it, including economic management, production and operation management, social and personal life.
Common successful domestic applications
The development of Internet of things has been filled with our lives all the time. What are the more conventional and successful applications in our country? Have you paid attention to these applications?
Railway carriage management. A RFID reader is placed on each side of the rail (both buses and wagons) with a reader on each side of the rail, spaced apart from each other. In this way, it is possible to keep abreast of all the trains on the railway line at all times, so as to facilitate the tracking, dispatching and safety control of trains.
Second generation ID card. The first generation ID card adopts polyester film plastic sealing, and later uses laser pattern anti-counterfeiting. While talking about the second generation ID card, have to mention his anti-counterfeiting technology innovation, the second generation ID card is a contactless IC chip card, a directional light color "the Great Wall" pattern, light, anti-counterfeit film optical storage "China CHINA", a string "JMSFZ" (pinyin: J M, n Sh reports de nF de nZh ng, a resident identity card), fluorescent printing "UV light show" the Great Wall pattern anti-counterfeiting technology.
The second generation ID card contains non contact IC chips, and it is a RFID chip with more scientific and technological content. The chip stores the basic information of the individual and reads the data in close proximity. When you need it, you can show the basic information about your identity by reading it on the reader. Moreover, the information of the chip, the format and the content are only provided by a certain manufacturer, so the anti-counterfeiting is remarkable and difficult to be forged.
Student cards at most universities in china. Speaking of campus life, besides the longing and memories of the beautiful youth, student card is essential that accompanied us through the ivory tower time documents, as we all know, the students' summer vacation students use cards to buy train tickets to enjoy half price concessions, but Chinese numerous colleges and universities, therefore, the relevant departments under a unified RFID chip is used to read and write. It stores the information about the number of trains used by the user and reduces it every time it is used. Moreover, it is not easy to forge and is easy to manage.
One card solution。 Many cards also use the Internet of things technology, such as: Municipal card, campus card can be classified as a relatively simple application of Internet of things.
ETC toll collection system. Now we go to some highway toll stations and find that there is no parking fee system and no one is on duty. As long as the vehicle is slowed down, different parking can be completed for information authentication and charging. Labour costs are reduced. Domestic earlier in the capital airport high-speed pilot, there are many parts of the country have done an attempt.
But since not only the charging system needs to be upgraded, it also needs to install identification chips for the vehicles that may pass. Since it is difficult to install all vehicles, ETC and manual charges are often retained in many places. Because artificial toll vehicles to slow down and stop in advance, each car charge in accordance with 15 seconds, before and after the actual about 30 seconds, at the peak stage of traffic congestion easily. Therefore, the conditions still have to implement ETC, not only to speed up the traffic speed, but also to save management costs. Of course, some places also consider employment issues and gray income, so the enthusiasm is not very high.
Application of Internet of things technology in other fields
In addition to these things and our lives are closely related to the Internet of things technology applications, Internet of things technology is also applied in different fields.
Equipment monitoring. The monitoring or control of buildings such as the thermostat things we often fail to complete, then the application of networking technology, can realize remote operation, even can save energy and simplify the maintenance procedure. The beauty of this Internet of things lies in its strong implementation, easy access to performance benchmarks, and timely improvements.
Machinery and infrastructure maintenance. According to the definition of the International Telecommunication Union (ITU), the Internet of things mainly solves the interconnection between goods and articles (Thing, to, Thing, T2T), to and Thing (Human), H2T (Human, to, Human, H2H). Unlike the traditional Internet, however, H2T refers to the use of a universal device to connect with an object, which makes the connection easier, and H2H refers to the interconnection between people that do not rely on PC. Because the Internet does not take into account the connection to any article, we use the Internet of things to solve this traditional problem. The Internet of things, as its name suggests, is the network of connected objects, and many scholars discuss the Internet of things
