Embedded system is the foundation of all things interconnection. Security improvement is the invaria

The Internet of Things (IoT) is an important part of a new generation of information technology and an important stage of development in the information age. As the name suggests, the Internet of Things is the Internet that connects objects. According to CSCO's forecast for the growth of the Internet of Things, by 2020, the number of IoT devices will exceed 50 billion. This rapid development has led to unprecedented opportunities for development of embedded systems. With the innovation of technology and functionality of traditional products in the Internet of Things, embedded systems have gradually evolved from isolated systems to networked systems, with penetration rates in products. Greatly improved. It is no exaggeration to say that the Internet of Things is the real spring of embedded systems.
Why does the Internet of Things need an embedded system
Embedded system is the basis of the Internet of things
What is the embedded system in the end? Broadly speaking, we can define this way. All special hardware and software systems with microprocessors and microcontrollers can be called embedded systems. In a narrow sense, we place greater emphasis on those stand-alone systems that use embedded microprocessors, have their own operating systems, and have systems with certain specific functions.
From the perspective of the development of the Internet of Things, the origin of the Internet of Things to promote the Internet of Everything is the embedded system. From the hardware point of view, embedded processors from the early independent operation of the microcontroller and to today's network interoperability MCU, has always been to "objects" as its mission; from a software perspective, the embedded operating system is the IoT device to accept The “soul” of the output information is responsible for the allocation of all software and hardware resources of the embedded system, task scheduling, control, and coordination of concurrent activities.
Embedded system embedded into the traditional application product gave the product a complete IoT interface. Associated with the physical parameters is the sensor interface of the forward channel; the control object of the backward channel is associated with the physical object; the human-machine interaction interface is realized for human-object interaction; and the communication interface is the object-object interaction.
The Internet of Things embedded system has its distinctive features:
Have data transmission paths;
Must have a certain storage function;
Have a CPU;
Have an operating system;
Have a dedicated application;
Follow the Internet of Things communications protocol;
There is a unique number that can be identified in the world network.
These distinctive features show that embedded systems have become a key part of the IoT industry.
Internet of Things and Embedded Systems Mutual Achievements
As open-source software becomes more and more mature, embedded systems have been widely used in open source software, such as the Linux operating system. However, before the rise of the Internet of Things, in addition to high security and reliability requirements in areas such as automotive electronics, aerospace, and defense, the traditional embedded operating system has seen slow growth and lack of profitable business models. And it is the concept of the Internet of Things that has been adopted in many fields to make the embedded operating system find a feasible landing solution. With the development of the Internet of Things cloud platform, the operating system embedded in the device is also being combined with the cloud platform to form a new Internet of Things. operating system. The Eclipes Foundation 2016 IoT Developer Survey revealed that open source Linux and RT operating systems are the mainstream of the Internet of Things market. However, with the continuous enrichment of Internet of Things applications, some lightweight IoT operating systems have begun to emerge. They have strong cloud-end interoperability, which can simplify the connection between terminals and platforms, and gradually become a mature commercial IoT terminal operating system. .
Achievements of Embedded Systems in the Field of Things
Agricultural Internet of Things
Agricultural Internet of Things (IoT) is the Internet of Things that participates in automatic agricultural control through real-time display of various instruments or as a parameter of automatic control. Taking the greenhouse control system as an example, the temperature, relative humidity, PH value, light intensity, soil nutrients, and CO2 in the environment are measured using the temperature sensors, humidity sensors, pH sensors, illuminance sensors, and CO2 sensors of the Internet of Things system. Concentration and other physical parameters ensure that crops have a good and suitable growth environment. The implementation of remote control enables technicians to monitor and control the environment of multiple greenhouses in the office.
The main technical applications of the agricultural internet of things include:
Embedded System Design and Implementation
Cloud-based traceability technology
Inter-network integration sub-layer design
Design and Implementation of Data Acquisition Module
Industrial Internet of Things (IIoT)
Industrial Internet of Things refers to the connection of production equipment and products in an industrial environment. With the advancement of the industry 4.0 process, the application of embedded systems in the industry is promising. For example, industrial robots, where the high-performance controller is a very complex embedded system; PLC used in factory automation is actually an embedded system.
Based on the embedded system, the industrial Internet of things uses RFID, sensors, two-dimensional codes and other means to obtain the information data of the products from production to sales to the end user at any time. The traditional industrial automation data collection is often limited to the production quality inspection stage.
The rapid development of industrial Internet of things has also promoted the innovation of embedded systems. The mergers and acquisitions and reorganizations between chip companies have intensified, and products have become more platform-oriented. Chips have continuously integrated more functions, and at the same time they have focused on software, cloud, and services.
Public Safety Monitoring Internet of Things
Public safety monitoring Internet of Things is characterized by wide coverage, multiple monitoring indicators, high continuity requirements, and the environment is not suitable for manual monitoring, and the perceived content of information is closely related to people's lives.
Application of Internet of Things technology, especially sensor network technology, builds an information system project consisting of a sensing layer, a network layer, and an application layer. The monitoring of public safety mainly includes ensuring the safety monitoring of various production scenarios, the monitoring of the safety of producers, the monitoring of the safety of specific items, the monitoring of personnel-intensive places, the monitoring of important facilities and equipment, and the accident emergency handling of scenes and personnel. , information collection of items, etc.
Of course, in addition to the above-mentioned fields, there have been attempts in the application of IoT embedded systems in areas such as smart transportation, telemedicine, smart homes, environmental monitoring, and smart grid monitoring.
The Development Trend of Embedded System in Internet of Things
The Internet of Things is infiltrating into a wide range of embedded system markets and is actively implementing higher security and adding new artificial intelligence (AI) elements.
In October 2016, a very large-scale DDoS attack hacked more than half of the U.S. Internet. The method used by hackers is to use a "botnet" consisting of 1.5 million devices, most of which are webcams.
Therefore, security enhancement is the next big trend in the development of the Internet of Things. In the era of Internet of Things, the biggest security problem of embedded systems comes from malicious attacks on the network. In order to fully protect MCUs or small MPUs, security solutions implemented using standard information technologies are indispensable. These security protocols include: TLS, IPSec/VPN, SSH, SFTP, secure boot and automatic callback, filtering, HTTPS, SNMP v3, secure wireless connection, encryption and decryption, encrypted file system, DTLS (for UDP security), and security E-mail etc.
artificial intelligence
Artificial intelligence and the Internet of Things (IoT) are important trends in the embedded field in the past two years. The industry believes that the two will be rapidly integrated and reshaped into an intelligent Internet of Things system. In this situation, embedded designers must have new thinking. The design of embedded systems has always been guided by market demand. In the era of intelligent Internet of Things, the system uses thinking that will be fully transformed, the internal components of the device are more detailed and more intelligent, and the external system integration must be more compact and diverse.
And, with the rapid development of the Internet of Things, the big data collected by the system comes along with it. Faced with enormous amounts of big data information, if it is obviously impossible to rely on manual review and classification, the computing power of the current IoT devices is also stretched. We need artificial intelligence to provide stronger data analysis capabilities and improve the system. Application efficiency.
