Embedded future will play a greater role because of the development of the Internet of Things(IoT)
- Sep 30, 2018 -

With the advancement of national information technology, electronic technology has also been more widely used. As a traditional electronic technology, embedded will play a greater role in the future due to the development of the Internet of Things.

Embedded system definition

An embedded system is a "special computer system that is completely embedded within a controlled device and designed for a specific application." According to the British Institute of Electrical Engineers, an embedded system is a control, monitoring or auxiliary device, machine, or factory operation. device of. Unlike general-purpose computer systems such as personal computers, embedded systems typically perform predefined tasks with specific requirements. Because the embedded system is only for a specific task, the designer can optimize it to reduce size and cost. Embedded systems are typically mass-produced, so individual cost savings can be scaled up with yields.

The role of embedded systems

Embedded systems are systems used to control or monitor large-scale equipment such as machines, devices, and factories. The embedded system generally recognized in China is defined as: application-centered, computer-based, software and hardware tailored to meet the strict requirements of the application system for functions, reliability, cost, size, power consumption and other special computer systems. Typically, an embedded system is an embedded processor control board in which the control program is stored in ROM.

In fact, all devices with digital interfaces, such as watches, microwave ovens, video recorders, and automobiles, use embedded systems. Some embedded systems also include an operating system, but most embedded systems implement full control from a single program. logic.

The core of an embedded system consists of one or several microprocessors or microcontrollers that are pre-programmed to perform a few tasks. Unlike general-purpose computers that are capable of running user-selected software, software on embedded systems is often temporarily unchanged; so it is often referred to as "firmware."

Features and applications of embedded systems

With the continuous popularity of medical electronics, smart home, logistics management and power control, embedded systems use their accumulated experience to value and grasp this opportunity, and find ways to apply sensing on mature platforms and products. The combination of units, extended connectivity and perceived support capabilities, to explore a field of IoT applications. As an embedded system composed of important technologies of the Internet of Things, the perspective of embedded systems helps to understand the essence of the Internet of Things profoundly and comprehensively.

This has two meanings: First, the core of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet. Second, its client extends and extends to any item and item for information exchange and Communication must have an intelligent terminal built by an embedded system. Therefore, the Internet of Things system is a system for information exchange and communication by connecting any item to the Internet through an information sensing device such as radio frequency identification (RFID), infrared sensor, global positioning system, laser scanner, etc. according to a contract. Architecture.

The Internet of Things not only provides sensor connectivity, but also has the ability to intelligently handle intelligent control of objects, which is what our embedded systems can do. It is true that the Internet of Things combines sensors and intelligent processing to expand its application areas with various intelligent technologies such as cloud computing and pattern recognition. Analyze, process and process meaningful data from the vast amount of information obtained by sensors to adapt to the different needs of different users and discover new application areas and application models.

Embedded systems are widely used in the Internet of Things, including intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire protection, industrial monitoring, environmental monitoring, street lighting control, landscape lighting control, building lighting control, square lighting control, Elderly care, personal health, flower cultivation, water monitoring, food traceability, enemy investigation and intelligence gathering.
