The development of the Internet of Things is the general trend. In addition to the Internet of Things, there are also sensor networks, the Internet, and the ubiquitous network. The Internet of Things and these networks have both connections and differences.
The difference and connection between IoT and sensor network
As the name implies, the Internet of Things emphasizes the connection between things, which is close to the essential attributes of things, while sensors emphasize technology and equipment, and are an objective expression of technology and equipment. Generally speaking, the Internet of Things and the sensor network have the same constituent elements, and they essentially refer to the same thing. The Internet of Things expresses this kind of things from the level of things, and the sensor network expresses this kind of things from the perspective of technology and equipment. The device of the Internet of Things is all objects, and the prominent one is an information technology, which is established to provide people with high-level application services. The equipment of the sensor network is a sensor. The most prominent one is sensor technology and sensor equipment. The purpose of its establishment is to obtain more massive information.
In detail, the sensor network can be called a sensor network. Two kinds of modules are needed to form a sensor network, one is "sensing module" and the other is "networking module". The sensor network pays more attention to the perception of object signals, such as sensing the state of the object and external environment information. However, the Internet of Things pays more attention to the identification and indication of objects. If you want to identify and indicate objects, you must use sensors, radio frequency identification and other devices at the same time. From this perspective, the sensor network is part of the Internet of Things, and the relationship between them is the relationship between the part and the whole, which means that the Internet of Things includes the sensor network.
The difference and connection between the Internet of Things and the Internet
In fact, the Internet is the foundation of the Internet of Things, and the Internet of Things is the upgraded Internet. In other words, the Internet of Things is an advanced form of the Internet. The main body of Internet connection is people, and the main body of Internet of Things connection is things, but the Internet of Things is not simply a connection to things. It first connects people and then extends to the connection to things. The Internet focuses on manual information collection and processing, and the Internet of Things focuses on artificial intelligence such as "cloud brain" for information collection and processing.
The relationship between the Internet and the Internet of Things is like the relationship between a father and a son. The Internet of Things is a new generation of the Internet and an innovation of the Internet. The difference between the two is mainly reflected in the following three aspects:
1. In terms of coverage, the coverage of the Internet of Things is much larger than that of the Internet. From the perspective of its main function, the main service object of the Internet is people, who can exchange information with each other through the Internet, which brings convenience to daily production and life. The birth of the Internet of Things is mainly to help humans manage things. If the earth is compared to the home of human beings, then the Internet of Things is the management of large and small items in the home for human beings. The Internet of Things can allow automatic exchange of information between things, and real-time monitoring and management of things. The difference between the Internet and the Internet of Things is that the Internet directly serves mankind, while the Internet of Things serves mankind indirectly. Compared with the Internet, the realization of the Internet of Things is relatively difficult, because the Internet service process is directly participated by humans. Due to their own subjective initiative, people can discover and solve problems in the Internet in time, but the Internet of Things is out of direct humans. Participate, the problems of objects are also analyzed, managed and corrected by artificial intelligence. But artificial intelligence is far less flexible than the human brain, so some specific problems are difficult to solve in time.
In terms of complexity, the Internet of Things is more than the Internet. In the future, the application of the Internet of Things will far surpass the Internet. The development of the Internet of Things industry will have a stronger and greater role than the Internet in terms of economic driving and social influence. The Internet solves the problem of human communication and realizes the alley and sharing of information between people. The Internet of Things not only communicates between people, but also communicates between people and things, things and things. Using the development technology of the Internet of Things, humans can achieve Intelligent management and intelligent decision-making control of things.
2. Internet terminals include desktop computers, notebooks, smart phones, tablet computers, etc. Using these Internet terminals, people can watch news, watch movies, send emails, receive emails, buy stocks, buy funds, order food, order air tickets, and so on. The connection between these terminals and the Internet can be wired or wireless. The terminals of the Internet of Things are countless sensors, which are connected into a network and connected to the Internet through a convergence node. The main connection method is wireless connection, which requires two processes. One is to use a reader to connect the RFID chip and the control host, and the other is to connect the control host and the Internet through a control node. It can be seen that the Internet of Things and the Internet have different access methods and application systems. Wireless sensor networks and RFID application systems are the two main ways for the Internet of Things to access the Internet. There are usually two ways for the Internet of Things to obtain data, one is automatically sensed by sensors, and the other is automatically read by RFID readers.
3. Compared with the Internet, the realization of the Internet of Things requires more technologies, including Internet technology, computer technology, wireless network technology, information communication technology, smart chip technology, etc. In other words, Internet technology is only one aspect of the technology involved in the Internet of Things. In addition, the difference between the Internet of Things and the Internet is that one acts on the virtual world and the other acts on the real world.
The difference and connection between the Internet of Things and the Ubiquitous Network
The combination of the Internet and the Internet of Things can be called the "ubiquitous network." Use the related technologies of the Internet of Things such as radio frequency identification technology, wireless communication technology, smart chip technology, sensor technology, information fusion technology, etc., and related Internet technologies such as software technology, artificial intelligence technology, big data technology, cloud computing technology, etc., It can realize people-to-people communication, people-to-things, and thing-to-things, so that the form of communication presents a multi-channel, omni-directional, multi-angle overall situation. This form of communication is not interfered by time, place, natural environment, human factors, etc., and can be carried out freely anytime, anywhere. The scope of the ubiquitous network is larger than that of the Internet of Things. In addition to the communication between people, people and things, and things and things, it also covers the relationship between people, the relationship between people and things, and the relationship between things and things. It can be said thatThe ubiquitous network includes all the content of the Internet of Things, the Internet, and the sensor network, as well as some areas of artificial intelligence and intelligent systems, is a more comprehensive network system that integrates multiple networks.
The biggest feature of Ubiquitous Network is the seamless connection of information. Whether it is communication, management, and service in people's daily life, or transmission, exchange, and consumption in production, or natural disaster prevention, environmental protection, and resource exploration, they all need to be connected through the ubiquitous network to achieve a unified network . And this kind of comprehensive and extensive tolerance for things is beyond the reach of the Internet of Things.
The connection between the Internet of Things and the Ubiquitous Network is that they all have the characteristics of networking, IoT, interconnection, automation, perception and intelligence.
From the above, it can be seen that the sensor network is a component of the ubiquitous network and the Internet of Things, and the Internet of Things is the stage of the development of the ubiquitous network. The communication network and the Internet The mutual collaboration and integration of the Internet of Things is the ultimate goal of the development of the ubiquitous network. From a development perspective, the future of network development will focus more on the development of ubiquitous network infrastructure to help humans achieve "4A" communication, that is, at anytime and anywhere (anywhere), Anyone and anything can communicate smoothly. Change our traditional production methods, work methods, and lifestyles through new information and communication technologies, and penetrate into all aspects of our life and work, including knowledge structure, social relations, economic and business life, politics, media, education, medical care and entertainment, etc. , Thereby solving social and economic problems.
