Simply understood, the Internet of Things is the use of electronic information technology to connect all the objects in the world to form a huge network. Take the Internet of Vehicles (a relatively large demonstration field currently under study) as an example. Every vehicle (including buses, private cars, trains, etc.). Unique identities are issued all over the country, just like each of us has our own unique ID card, each car has a unique electronic license plate number, and then all roads are equipped with many sensors and so on. We can use some radio frequency identification technology and RFID technology (just like when we pay for things in the supermarket, it is also radio frequency identification, that is, we can know what we are buying with a brush), and then the country has a large central information processing platform, which is to be realized through the current technologies such as cloud computing and mass storage. The platform can receive the information of all vehicles in all sections returned by all sensors. Because there is a lot of data, a large amount of running, and a great demand for running speed, it should be realized through technologies such as cloud computing and mass storage. Through such a central information platform, the management department can quickly know which section a specific bus is currently running on, and by the way, it can also learn some other information of the bus (such as how many people are carried, running speed, destination, etc.). ), so as to realize some functions, such as timely reporting to the traveling residents when the next bus will arrive and which road section is currently congested (if there is a slow traffic flow in which road section, this road section will be blocked). You can also link each train with the owner's bank card, directly read the electronic license plate number of passing vehicles on the highway section, and pay by credit card without stopping, thus reducing air pollution and traffic congestion. A car owner can also query the running information of other cars through the central information processing platform, so that all the cars in the country form a huge network, which is the so-called car networking. The Internet of Things is a broader concept than the Internet of Vehicles. The only identity includes not only cars, but also household appliances, books, bridges, houses and other objects, and then these things are connected by the same technology to form a huge network. The concept of Internet of Things is being heated up now, but it will take a long time to fully realize it. Once it is realized, it will bring immeasurable changes to the world.
