The new generation of information technology is the integration of Internet and embedded system to the advanced stage

With the rapid development of embedded technology, the Internet has entered the era of Internet of things. A large number of devices required by the Internet of things do not rely on the interaction between people to establish connections, but are more connected to a place through protocols, communications, programming and other means. In other words, the purpose of the Internet of things is to make all items have computer intelligence, rather than the form of general-purpose computers, and connect these "intelligent" items with the network, which requires the support of embedded technology.

After years of rapid development, the information industry has experienced two waves of computers, the Internet and mobile communication networks. The Internet of things is known as the third wave of the world's information industry, representing the next generation of information development technology. The Internet of things is a convergent application and technology improvement that appears after the development of modern information technology to a certain stage, which aggregates and integrates various perception technologies, modern network technologies, artificial intelligence and automation technologies, Make people talk with things wisely and create a wise world.

The development of China's Internet of things industry is guided by application, and there is a progressive trend of market segmentation from public management and service market, to enterprise, industry application market, and then to individual household market. At present, the Internet of things industry in China is still in the early concept introduction period and the gradual formation stage of the industrial chain. There is no mature technical standards and perfect technical system, and the overall industry is in the brewing stage. After the concept of Internet of things is put forward, it will be necessary to start the animal networking market with the government application demonstration project for the public management and service fields with urgent needs. Further, with the continuous maturity of public management and service market application solutions, enterprise agglomeration, and the continuous integration and improvement of technology, a relatively complete IOT industrial chain will gradually be formed, which will drive the application market of large enterprises in various industries. The human application market will develop with the gradual maturity of applications in various industries and the improvement of services and processes.

Embedded technology is different from general computer technology. We know that general-purpose computers are mainly used to interact with people and work according to the instructions issued by people. In most cases, the embedded system can process events independently according to its own "perception", so it puts forward higher requirements for the timeliness and reliability of event processing.

Generally speaking, the embedded system should have the following characteristics: specificity, encapsulation, real-time, reliability. Specificity refers to the embedded system used for specific equipment to complete specific tasks. Unlike general-purpose computer systems, it can complete a variety of different tasks. Encapsulation refers to the embedded system that is usually hidden in the target system and not noticed by the operator. Real time refers to the ability of embedded system to respond to events or user intervention in a predictable time, compared with the frequency of actual external events.

With the evolution from embedded to the Internet of things, the technical complexity is getting higher and higher, but for the developers of the Internet of things, the threshold will be lower and lower. More developers can develop more innovative products based on simple script language, rich ecosystem and tools, so as to meet the needs of everyone for convenient life, efficient production and so on. At the same time, the development of the Internet of things is not only the evolution of technology, but also the evolution of business model. Through technological innovation, the threshold for developers has been lowered, so that the development of the Internet of things is no longer like embedded development, which is the patent of niche and geek, but a base for the public to develop innovation. As a result of this change, combined with the rapid development of cloud technology, the business model of the Internet of things is no longer based on selling development boards, but on selling services, cloud resources and innovative products. This massive and high value-added business has supported the emergence of 10 billion or even 100 billion companies in the Internet of things.

Nowadays, with the development of the industry, the scarcity of talent resources is an inevitable result, and more and more students choose embedded development and other majors. These high-quality talents will also appear in all walks of life, so that it is no longer an independent industry, but as a bridge for all walks of life to communicate and connect, so that all industries can work more efficiently and closely.

The Internet of things is an important part of the new generation of information technology, and it is the integration of the Internet and embedded systems to the advanced stage of development. As an important technology of the Internet of things, embedded system perspective is conducive to a profound and comprehensive understanding of the essence of the Internet of things. Both general-purpose computers and embedded systems can be traced back to semiconductor integrated circuits.
