Scope of Application of Single Chip Microcomputer

Single-chip computer penetrates into all areas of our lives, and it is almost impossible to find out which field has no trace of single-chip computer. Missile navigation device, control of various instruments on aircraft, computer network communication and data transmission, real-time control and data processing of industrial automation process, various intelligent IC cards widely used, safety assurance system of civil luxury cars, control of video recorders, cameras, automatic washing machines, programmed toys, electronic pets and so on, are inseparable from the single. Chip machine. Not to mention robots, intelligent instruments, medical devices and various intelligent machines in the field of automatic control. Therefore, the study, development and application of single-chip computer will bring up a group of scientists and engineers of computer application and intelligent control.

SCM is widely used in instruments, household appliances, medical equipment, aerospace, intelligent management of special equipment and process control. It can be roughly divided into the following categories:
.
Intelligent Instrument

MCU has many advantages, such as small size, low power consumption, strong control function, flexible expansion, miniaturization and convenient use. It is widely used in instruments and meters. Combined with different types of sensors, it can measure physical quantities such as voltage, current, power, frequency, humidity, temperature, flow rate, speed, thickness, angle, length, hardness, elements and pressure. The use of single-chip control makes the instrument digital, intelligent and miniaturized, and its function is more powerful than the use of electronic or digital circuits.

For example, precision measuring equipment (voltmeter, power meter, oscilloscope, various analyzers).

Industrial Control

MCU has the advantages of small size, strong control function, low power consumption, strong adaptability to the environment, flexible expansion and convenient use. It can be used to form various control systems, data acquisition systems, communication systems, signal detection systems, wireless sensing systems, measurement and control systems, robots and other application control systems. For example, intelligent management of factory assembly line, intelligent control of elevator, various alarm systems, and computer networking constitute secondary control system, etc.

Household appliances

Household appliances are widely controlled by single-chip computer, ranging from rice cooker, washing machine, refrigerator, air conditioner, color TV, other audio and video equipment, to electronic weighing equipment and white household appliances.

Network and Communication

Modern single-chip computers generally have communication interfaces and can easily communicate with computers. They provide excellent material conditions for the application between computer networks and communication devices. The communication devices basically realize the intelligent control of single-chip computers, ranging from mobile phones, telephones, small program-controlled exchanges, building automated communication call systems, train wireless communication, to daily life. Mobile phones, trunked mobile communications, radio walkie-talkies can be seen everywhere in the work.

Equipment field

MCU is also widely used in medical equipment, such as medical ventilator, various analyzers, monitors, ultrasound diagnostic equipment and hospital bed call system.

Modular system < br />
Some special microcontrollers are designed to achieve specific functions, so that they can be modularized in various circuits without requiring users to understand their internal structure. For example, music integrated microcontroller, seemingly simple functions, microminiaturization in pure electronic chips (different from the principle of tape machine), requires complex computer-like principles. For example, music signals are stored in memory in digital form (similar to ROM), read out by microcontroller, and converted into analog music electrical signals (similar to sound cards).

In large-scale circuits, this modular application greatly reduces the volume, simplifies the circuit, reduces the damage and error rate, and is also easy to replace.

Automotive Electronics

MCU is widely used in automotive electronics, such as engine controller in automobile, intelligent electronic controller of automotive engine based on CAN bus, GPS navigation system, ABS anti-lock braking system, braking system, tire pressure detection, etc.

In addition, MCU has a very wide range of applications in the fields of industry, finance, scientific research, education, power, communication, logistics and national defense, aerospace and other fields.
