The Internet of things develops very fast in China, and it has become one of the national strategic industries. As we all know, the Internet of things is composed of four parts: equipment, system, network and platform, while the embedded system is very important in the IOT industry, so what kind of existence it is in the industry, this paper mainly describes its role and characteristics in IOT.

Embedded system is used to control or monitor large-scale equipment such as machines and devices. It is an application-based system, which is generally composed of one or several microprocessors or single-chip computers. Unlike general-purpose computers, which can run software, the software on embedded systems is usually temporary.

With the development of IOT technology, its application is more and more extensive, involving industry, agriculture, communication, medical treatment, consumer electronics, etc. Because IOT needs more sensors and chips, which brings more hardware costs to the operation; the advantages of embedded system are miniaturization and low cost, which can play its role in the IOT industry.

What is the application of embedded system in the Internet of things industry

The role of embedded system in the IOT industry can be understood as cost reduction and intelligence. More and more operators apply embedded technology to mature platforms and products, which can expand the perception of objects and form powerful intelligent terminals. In the IOT network, the embedded system provides more accurate data for the product. It and the sensor together constitute an intelligent big data network to realize the channel communication between people and objects.

According to the editor of OFweek electronic engineering network, the embedded system needed by IOT must have four characteristics, one is the ability of data transmission and processing; the other is the ability of storage; the third is compatible with most applications; the fourth is to adapt to most communication protocols and interfaces. Only the embedded system with these functions can conform to the trend of the era of “interconnection of all things”.

In the IOT industry, embedded systems exist all the time, but the value of existence is big or small. In the early days of IOT, embedded systems played more communication functions to realize interconnection. With the development of integrated circuit and artificial intelligence, embedded system plays a greater role. Today’s embedded system can carry out hardware distribution, task scheduling and control. Even in some industrial Internet fields, embedded system integrates intelligent sensors to achieve automatic data collection and processing, which requires more sensor modules.

Nowadays, the software technology is more and more developed. The design idea of software can also affect the layout and development of hardware. The combination of software and hardware has become a new trend. Considering the cost and power consumption, in many wide area Internet of things systems, embedded operating system and cloud computing system want to cooperate with each other to complete the huge data processing needs. Embedded system is more and more widely used in IOT. In addition to industrial Internet of things, there are also Agricultural Internet of things and home Internet of things. In the future, with the promotion of the market, more and more embedded systems will appear in the network.

Industrial Internet of things needs to realize the connection of machines, equipment and people. Embedded system emphasizes stability and security in industrial application. For example, PLC in industry is also an embedded system. There are many sensors, two-dimensional codes, chips, etc. which are necessary equipment to realize industrial automation. The industrial Internet of things needs the update of embedded system, more general embedded products, and more integration.

In the Agricultural Internet of things, the utilization rate of sensors and instruments is very high. The great role of embedded system is to coordinate and analyze the working conditions of these devices, and achieve higher working efficiency by processing these data. Because agriculture is greatly affected by the environment, the cost of the system and the convenience of replacement need to be considered in the design of the system scheme.

The characteristics of the medical Internet of things are simple, standardized and reliable. For the embedded system, it needs higher performance, higher stability equipment, and high requirements for integration. With the wide application of AI technology in medical treatment, the embedded system needs to be upgraded and improved. Medical information is to bring convenience to the hospital, and the convenience of system operation is the first.

With the popularization of IOT, the data becomes larger and larger, which brings a lot of hidden dangers to devices and networks. In the future, these devices need more powerful data analysis and collection capabilities to adapt to the development trend of the industry, and the embedded system is their core processor.
