In the application technology of Internet of things, embedded technology is very important. But at least 60% of people don’t know what embedded technology is. With the advent of the Internet of things era, embedded technology has been developed unprecedented, whether from industrial applications, or the outbreak of intelligent hardware, or big data and so on.

Simply speaking, embedded technology is application-oriented, based on computer technology, and software and hardware can be tailored. It is suitable for application systems with strict requirements for function, reliability, cost, volume and power consumption. Embedded system is a complete computer system including hardware and software. Its definition is: “embedded system is application-oriented, based on computer technology, and software and hardware can be tailored. It is suitable for special computer system with strict requirements on function, reliability, cost, volume and power consumption of application system.” The computer used in the embedded system is a special microprocessor embedded in the controlled object, but its function is more specialized than that of the general computer. It has a special computer system specially designed for a certain aspect, suitable operation speed, high reliability and low cost that the general computer cannot have.

For a simple example, your smartphone is actually an embedded system. Its system is configured with some hardware such as storage, CPU and battery, but considering the power consumption, a system is specially customized for the smartphone. Imagine that if the smartphone still uses the CPU of the desktop computer, the final product has to weigh dozens of Jin. Does anyone else buy that kind of mobile phone? Therefore, embedded system is a customized system for product requirements.

Embedded technology originated from single-chip technology, is the core of all kinds of digital electronic and mechanical and electrical products, mainly used to realize the control, monitoring or management of hardware equipment. In the 21st century, about 90% of the development of computer applications in all walks of life will involve embedded development. The annual growth rate of the global embedded software market is more than 12.5%. The annual industrial output value brought by the embedded system is up to 1 trillion dollars. In the next three years, the embedded software industry will maintain a compound annual growth rate of more than 40%.

A mature embedded engineer basically needs to understand, application development, underlying development, of course, there will be a lot of them here. The application prospect of embedded system is very wide, Timon technology is more involved in the industrial field of embedded system control.

Industrial automation equipment based on embedded chip will get great development. At present, there are a large number of 8, 16, 32-bit embedded Microcontrollers in application. Networking is the main way to improve production efficiency and product quality, reduce human resources, such as industrial process control, digital machine tools, power system, power grid security, power grid equipment monitoring, petrochemical system. As far as the traditional industrial control products are concerned, the low-end type usually adopts 8-bit single chip microcomputer. However, with the development of technology, 32-bit and 64 bit processors have gradually become the core of industrial control equipment, which will surely get considerable development in the next few years.

Industrial equipment is the largest category of mechanical and electrical products. In the current industrial control equipment, industrial computers are widely used. These industrial computers generally use industrial grade processors and various devices, of which x86 MPU is the most. The requirements of industrial control are often high, requiring a variety of equipment interfaces. In addition to real-time control, the equipment status, sensor information, etc. must be displayed on the display screen in real time. These 8-bit microcontrollers can not meet the requirements. In the past, most of them used 16 bit processors. With the rapid development of processors, 32-bit and 64 bit processors gradually replaced 16 bit processors, further improving the system performance. PC104 bus system, small size, stable and reliable, has been favored by many users. However, these industrial computers often use DOS or Windows systems. Although they have the characteristics of embedded, they cannot be called pure embedded systems.

Embedded technology is very important in Internet of things application technology

In addition, industrial controller and device controller are the world of all kinds of embedded processors. These controllers often use more than 16 bit processors. Various MCU, arm, MIPs, 68K series processors occupy the core position in the controller. These processors provide abundant interface bus resources, through which data acquisition, data processing, communication and display (generally led or LCD) can be realized. Recently, Philips and arm jointly launched 32-bit RISC embedded controller, which is suitable for industrial control. It adopts the most advanced 0.18 μ m CMOS embedded flash memory processing technology. The operating voltage can be as low as 1.2V, and it can also reduce the manufacturing cost by 25% to 30%. It is a cost-effective solution for the final user in the industrial field.

Embedded technology is particularly important in industrial control, which belongs to the core of control. Timon technology continues to optimize the embedded system, and strive to create a high-performance, high reliability non-traditional industrial control equipment for users.
