The development of Internet of Things technology
The Internet of Things refers to the service network formed by the Internet of Everything. It empowers objects and environments in the physical world through intelligent terminals and devices, enabling objects and objects to perceive, communicate and interact with each other to convey their internal state or external environmental information. . Broadly speaking, the Internet realizes the sharing of information between people. The Internet of Things not only refers to the exchange of information between people and things, but also between people and things, and through the network environment. Various sensing devices (such as various types of sensors) are combined with intelligent terminals (such as various types of intelligent hardware) to realize the digitization of everything by using the Internet of Things, realizing self-intelligent identification of objects, active location tracking, spontaneous lifecycle management, and organization. Service delivery and other functions.
Although the Internet of Things has been challenged and questioned in terms of equipment and physical facilities security and data privacy in the history of development, it cannot be a hindrance to the rapid development of the Internet of Things. Human beings embrace this historic opportunity with an open mind and will quickly IoT technology is put into use, and it is expected that in this wave of technological change, people's lives and work methods will be changed with each passing day.
In 2017, the Ministry of Industry and Information Technology released the "13th Five-Year Plan for the Internet of Things", pointing out that China's Internet of Things has entered a new stage of "cross-border integration, integrated innovation and large-scale development", with smart wearable devices, smart appliances, and intelligence. Tens of thousands of new terminals, such as networked cars and intelligent robots, will access the network and generate massive amounts of data. Internet-related applications will have a breakthrough growth and promote social production, social management and residents' lifestyles to be more networked and refined. Transformation and intelligent direction.
According to CCID Consulting's data from the Ministry of Industry and Information Technology, China's IoT equipment reached 1.21 billion units in 2017. It is expected that the number of Internet of Things devices in China will increase to 5.38 billion units by 2025. In 2014, the scale of China's Internet of Things industry reached 632 billion yuan, a year-on-year increase of 22.6%. In 2015, the industry scale reached 750 billion yuan, a year-on-year increase of 29.3%. By 2020, the overall size of the Internet of Things in China will reach 2 trillion yuan.
The IoT technology architecture consists of four levels: the awareness layer, the transport layer, the platform layer, and the application layer. The sensing layer at the bottom layer relies on various sensors or intelligent hardware devices such as image capture devices, RFID sensors, sensors, and GPS locators to realize the sensing and interactive control of physical objects and events; the transport layer is mainly Through various communication protocols, the information collected by the sensing layer is transmitted to the platform layer through various networks (wired and wireless, short-range and long-distance); the platform layer uses cloud computing, big data, artificial intelligence and other means to perceive information. Convergence analysis and processing, through the middleware and industry applications to achieve convergence; the final application layer will put the Internet of Things technology in various sub-sectors of industrial application scenarios, thus achieving service functions for the masses of users.
