In recent years, in various conferences, exhibitions and news, we often hear some words such as “Internet of Everything”, “IOT” and “Internet of Things”, and we often see some words describing the Internet of Things as “connecting things and things. The magical network of all things.
Do you really know what the Internet of Things is? #
The Internet of Things, as the name implies, is a network that connects various “things” through certain technical means to realize the connection and control between things and people and things; it is an extension and expansion of the network on the basis of the Internet. , a huge network can be formed by combining various information sensing devices with the network, realizing the interconnection of people, machines and things at any time and any place
Relying on the development of modern communication technology, technologies such as wireless local area network, Bluetooth, Zigbee and even 5G have been widely used in the Internet of Things, which makes humans no longer just control the objects around them. This control has been extended to more and more distant places. objects, and even larger systems.
How are things-things and people-things related? #
The main components of the Internet of Things can be divided into four layers, namely the perception layer, the network layer, the support layer and the application layer. As one of the important components of the perception layer of the Internet of Things, sensors are the foundation of the entire Internet of Things.
There is a huge amount of data information in the IoT system, and the source of this information is the sensor located at the terminal. Sensors are not only an extension of human senses, but also a “language” for communication between objects in the era of “Internet of Everything”. Sensors are able to take specific inputs of light, heat, motion, moisture, pressure, or any of a number of other environmental phenomena and convert them into numerical values that humans can read and use.
With the continuous development of the Internet of Things, sensor technology is also advancing rapidly, and various sensors have been applied to different fields, becoming the main means and way to obtain information in the Internet of Things.
We all say that the Internet of Things can realize the “Internet of Everything”, but what can the high-level skills of the Internet of Things help us do?
After a long period of silence since the Internet of Things technology was proposed more than 20 years ago, it has finally been able to show its talents today with the rapid development of science and technology. For example, in the era of Industry 4.0, we use sensors to monitor and control various parameters in the production process to keep the equipment in normal working condition; in the field of smart home, sensors are used to realize the functions of users and lighting, refrigerators, air conditioners, audio, etc. It is the basis of home-like interaction; in autonomous driving, it is even more necessary to collect and process traffic and environmental data through sensors, so as to ensure the safe driving of cars on the road… Even the shared bicycles and shared bicycles that are commonly used in our lives. Internet of Things technology is also used in charging treasures.
For now, the Internet of Things is still in a stage of vigorous development. Unlike the traditional Internet of Things, it can form the corresponding Industrial Internet of Things according to different industries: at the same time, it complements the development of the traditional Internet of Things. In the future, the development of the Internet of Things will involve various aspects of more industries and fields. The Internet of Things will not only change human life, but also reflect the advantages of the Internet of Things in environmental protection, industrial production, and medical diagnosis.
