Microcontroller application areas

Industrial automation control is one of the earliest fields to adopt single-chip microcomputer control. In measurement and control systems, process control, and mechatronics equipment, single-chip microcomputers are mainly used to achieve logic control, data acquisition, calculation processing, data communication, and other purposes. Single-chip microcomputers can be used alone to achieve some small-scale control functions. As a bottom-level detection and control unit, combined with a host computer, it can form a large-scale industrial automation control system. Especially in mechatronics technology, the structural characteristics of single-row grades make it easier to play its advantages of integrating mechanical, microelectronics, and computer technologies.

2. Application in intelligent instruments

The instrument system with a dot tablet inside is called an intelligent instrument, also known as a microcomputerized instrument. Most of these instruments use single-chip microcomputers for information processing, control and communication. Compared with non-intelligent instruments, their functions have been enhanced, with additional functions such as data storage, fault diagnosis, and network centralized control. Using single-chip microcomputers as the core to form intelligent instruments has become a trend in the development of automation instruments.

3. Application in household appliances

Single-chip microcomputers are perfect in functions, small in size, cheap, and easy to embed, making them very suitable for controlling household appliances. Household appliances embedded with single-chip microcomputers have realized intelligence, which is an upgrade of traditional household appliances. They are now widely used in washing machines, air conditioners, televisions, video disc players, microwave ovens, refrigerators, rice cookers, and various audio-visual equipment.

4. Application in information and communication products

Information and communication products are highly automated and intelligent, and many of their functions cannot be completed without the participation of single-chip microcomputers. The most representative and widely used products here are mobile communication devices. For example, the control chip in a mobile phone is a dedicated single-chip microcomputer. In addition, single-chip microcomputers are also indispensable in computer peripherals such as keyboards and printers. New single-chip microcomputers generally have communication interfaces, which can easily communicate data with computers, creating conditions for providing connection services between computers and network devices.

5. Application in office automation equipment

Most of the office automation equipment now has a single-chip microcomputer control core embedded in it, such as printers, copiers, fax machines, plotters, attendance machines, and telephones. Through single-chip microcomputer control, not only can the basic functions of the equipment be completed, but also data communication with the computer can be realized.

6. Application in commercial marketing equipment

In commercial marketing systems, microcontrollers have been widely used in electronic scales, cash registers, barcode readers, IC card readers, taxi meters, as well as warehouse safety monitoring systems, shopping mall security systems, air conditioning systems, refrigeration insurance systems, etc.

7. Application in the field of medical equipment

Microcontrollers are also widely used in medical facilities and medical equipment. For example, they have been used in medical ventilators, various analyzers, medical monitors, ultrasonic diagnostic equipment, and bed call systems.

8. Application in automotive electronics

Modern automobile centralized display systems, power monitoring and control systems, automatic driving systems, communication systems, and operation monitors are all inseparable from single-chip microcomputers. In particular, in automobile control systems that use fieldbuses, nodes with single-chip microcomputers as the core not only complete complex control functions through coordinated and efficient data transmission, but also simplify the system structure.
