It is now an era that enters all things, intelligent society, but all this is still inseparable from the credit of smart hardware, then this is to involve embedded relationships.
Although the embedded system has more than 30 years of history, it has been hidden behind, and since the Internet of Things has risen to the national strategy, the embedded system has also walked from the background to the front desk.
Below we will discuss the relationship between the Internet of Things and embedded, and introduce the characteristics and characteristics of embedded and Internet of Things.
The relationship between the Internet of Things and the embedded type:
1. The Internet of Things is an important part of the new generation of information technology. It is the integration of the Internet and the embedded system to the advanced phase.
2. As an important technology consisting of an important technique of the Internet of Things, an embedded system perspective helps to understand the nature of the Internet of Things.
3. Whether it is a general purpose computer or an embedded system, you can trace the semiconductor integrated circuit. The birth of the microprocessor provides a normalized intellectual kernel for human tools.
4. The general microprocessor and embedded processor on the basis of the microprocessor form two major branches of the modern computer knowledge revolution, namely the independent development era of universal computers and embedded systems.
5. General Computers have experienced the independent development path from the smart platform to the Internet; the embedded system has experienced the indigenous development path of Wisdom Terraces to the Local Wisdom.
6. The Internet of Things is a product of the Internet and an embedded system standing or a local domain combination of the embedded system.
7. In the Internet of Things, the microprocessor's infinite dispersion, with "smart cell" form, gives the intelligence characteristics of "smart earth".
Embedded profile:
IEEE (InstituteOfelectricalandelectronicsengineers, US Electrical and Electronics Engineer Association) defines the embedded system: "For control, monitoring, or means of applying device and device." The original text is: DevicesusedToControl, MonitororassistTheOperationOfequipment, Machineryorplants.
The embedded system is a dedicated computer system as part of the device or device. Typically, an embedded system is an embedded processor control panel stored in the ROM. In fact, all devices with digital interfaces, such as watch, microwave, recorders, cars, etc., all embedded systems, some embedded systems also include operating systems, but most embedded systems are implemented throughout the entire program Logic.
Definition from the application object, the embedded system is a complex of software and hardware, and also covers an accessory device such as mechanical. Domestic universally identified embedded systems are defined as centered, based on computer technology, hardware and software can be cropped, adapt to application systems to function, reliability, cost, volume, power consumption, etc. Strict requirements. Computer system.
I. Network Introduction:
IoT (InternetoftHings, abbreviation: IoT) is based on Internet, traditional telecommunications networks, etc., allowing all common objects that can exercise independent features to interconnect. Its application is mainly including transportation and logistics, industrial manufacturing, health care, intelligent environment (family, office, factory), etc., has a vast market prospect.
What is the Internet of Things technology?
The core and foundation of "Internet of Things Technology" is still "Internet technology", an extension and extended network technology based on Internet technology, its client extends and extension to any item and item, information exchange and Communications.
There are three key technologies in the Internet of Things applications.
1. Sensor technology, this is also key technologies in computer applications. Everyone knows that the most computer processing is digital signal so far. Since there is a computer, a sensor has been required to convert an analog signal into a digital signal computer.
2, RFID tag is also a sensor technology, RFID technology is integrated technology integrating wireless RF technology and embedded technology, and RFID has broad application prospects in automatic identification and item logistics management.
3. Embedded system technology: It is a complex technique integrating computer hardware and software, sensor technology, integrated circuit technology, electronic application technology. After decades of evolution, intelligent terminal products featible with embedded systems are everywhere; small to people around people, satellite systems that are large to aerospace. The embedded system is changing people's lives and promoting industrial production and the development of defense industries. If you use the human body to make a simple metaphor, the sensor is equivalent to the human eyes, nose, skin and other senses. The network is used by the nervous system to deliver information. The embedded system is a human brain. After receiving the information, it is classified after receiving the information. Process. This example is very similar to the location and function of the sensor, the embedded system in the Internet of Things.
