Embedded system--an important technical component of the Internet of Things
Since the concept of the Internet of Things was born in the United States, the Internet of Things has become an important part of the new generation of information technology, which is the integration of the Internet and embedded systems at the advanced stage. As an embedded system composed of important technologies of the Internet of Things, the perspective of the embedded system helps to deeply and comprehensively understand the essence of the Internet of Things.
This has two meanings: first, the core of the Internet of Things is still the Internet, which is an extension and expansion of the Internet; second, its user terminal extends and extends to any item and item, exchange information and Communication must have an intelligent terminal built with an embedded system. Therefore, the Internet of Things system is a system that uses RFID, infrared sensors, global positioning systems, laser scanners and other information sensing equipment to connect any item to the Internet for information exchange and communication according to the agreed protocol Architecture.
The Internet of Things not only provides the connection of sensors, but also has the capability of intelligent processing, which can implement intelligent control of objects. This is what we can say today with embedded systems. It is true that the Internet of Things combines sensors and intelligent processing, and uses cloud computing, pattern recognition and other intelligent technologies to expand its application fields. Analyze, process and process meaningful data from the massive information obtained by the sensors to meet the different needs of different users and discover new application areas and application models.
In summary, the embedded system of the Internet of Things has its distinctive characteristics.
1. There must be a data transmission channel;
2. There must be a certain storage function;
3. A CPU is required;
4. An operating system is required;
5. There must be a special application;
6. Follow the communication protocol of the Internet of Things;
7. There is a unique number that can be identified in the world network.
These distinctive features indicate that embedded systems have become key technologies in the Internet of Things industry. Embedded system technology is a complex technology that integrates computer hardware and software, sensor technology, integrated circuit technology, and electronic application technology. After decades of evolution, smart terminal products featuring embedded systems are everywhere; from MP3s around people to satellite systems in aerospace. Embedded systems are changing people's lives and driving the development of industrial production and defense industry. If the Internet of Things is used as a simple analogy of the human body, the sensor is equivalent to the human eyes, nose, skin and other senses. The network is the nervous system used to transmit information, and the embedded system is the human brain. After receiving the information, it must be classified deal with. This example vividly describes the position and role of embedded systems in the application of the Internet of Things industry.
With the rapid development of enterprises in China's Internet of Things industry, the Internet of Things technology research and development, standard development, industrial cultivation and industrial application have already had a certain foundation. However, if the key core technologies of IoT enterprises need to be broken through, they cannot grasp the initiative of enterprise development. Chenhan Electronics, which has grown up with the growth of the Internet of Things industry, not only has the identity of a third-party independent design company and industry solution provider for embedded systems, but also fully complements the enterprises and scientific research institutes in the Internet of Things industry. And fully understand and grasp the scientific development laws of the Internet of Things, and promote the application of the Internet of Things and the healthy development of the industry.
As a member of Freescale Global Designer Alliance, Chenhan Electronics is the only design service company in China that spans a full range of i.MX products. From providing product-level underlying platforms to product-based commissioned design services, it has now become a high-tech enterprise providing solutions for the Internet of Things industry. Embedded system services have been tried in the fields of green agriculture, industrial monitoring, mobile medical, mobile office, military-industrial collaboration, public safety, urban management, telemedicine, smart home, smart transportation and environmental monitoring, smart grid monitoring, etc. .
At present, medical electronics, smart home, logistics management and power control are very popular. No matter what, the embedded system values ​​and seizes this opportunity, using its own accumulated experience on embedded systems, to find a way to mature platforms On the basis of the product and the product, through the combination with the application sensing unit, the support ability of the Internet of Things and perception is expanded, and the IoT application in a certain field is explored. By expanding the application processing and analysis functions of the background (also known as the IoT hub server), the Development on the integrated system of IoT applications. We have integrated solutions in the fields of mobile medicine, smart transportation, smart farming and live aquatic product transportation, smart cities, smart grid monitoring, catering services, industrial field mobile office and smart file management.
The opportunities shared by the embedded system and the Internet of Things industry are ubiquitous. We conclude that: whether it is the three elements of the Internet of Things (perception), or the Smart Earth 3i, CPS 3C, it is actually talking about one thing: people , The harmonious development of machine and object. Therefore, this embedded system has always had very high requirements: to be multifunctional, low power consumption, and miniaturization, these are already being done. The intelligent collection of wireless sensor nodes in systems and solutions tends to be integrated, and the design Embedded systems pursue networking. Let's make an analogy: If you copy the Internet to the Internet of Things now, this will not technically work, because our object-oriented data is continuous, dynamic, and unstructured. Therefore, browsing cannot be simply set as an embedded browser, so it is necessary to establish information middleware between low-end and high-end, and to build middleware applications for the Internet in specific fields such as automotive electronics, home networks, mobile devices, and industrial environments. From the perspective of the application of the embedded system: many cases are realized from a terminal to a terminal by a certain technical means, generally a closed-loop application. The closed loop is only within a specific scope or application area, and it cannot reach the open loop, such as information services in the public domain. Because the development of the Internet of Things is actually limited by the application model, if you want to open the loop, you will face a complex problem: what kind of business model to find and who will pay for the infrastructure. Chenhan Electronics is also working hard to establish a closed-loop application model with leading communication with various industries and industries and infrastructure.
At present, there are still many standards related to the Internet of Things, but on the whole, it is still a distance away from the ideal Internet of Things standards.
The embedded system is an important technical foundation of the Internet of Things. When Americans put forward the concept of Internet of Things, Chenhan Electronics, which has a local spirit, interprets the crystallization of the American technology and embedded systems. It must be hard work in the application of the Internet of Things industry. , Together with companies committed to creating value for the development of China's Internet of Things industry, work together!
