First, the circuit board
Single-chip microcomputer has penetrated into every field of our lives, and it is almost difficult to find out which field has no trace of single-chip microcomputer. Missile navigation device, control of various instruments on the plane, computer network communication and data transmission, real-time control and data processing of industrial automation process, various intelligent IC cards widely used, safety guarantee system of civilian luxury cars, control of video recorders, video cameras, automatic washing machines, program-controlled toys, electronic pets, etc. , are inseparable from the single chip microcomputer. Not to mention robots, intelligent instruments, medical instruments and various intelligent machines in the field of automatic control. Therefore, the research, development and application of single chip microcomputer will bring up a group of scientists and engineers in computer application and intelligent control.
Microcontrollers are widely used in the fields of intelligent management and process control of instruments, household appliances, medical equipment, aerospace and special equipment, which can be roughly divided into the following categories:
Second, intelligent instruments.
Single-chip microcomputer has the advantages of small size, low power consumption, strong control function, flexible expansion, miniaturization and convenient use, and is widely used in instruments and meters. Combined with different types of sensors, physical quantities such as voltage, current, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, elements and pressure can be measured. The use of single-chip microcomputer control makes the instrument digital, intelligent and miniaturized, and its function is more powerful than that of electronic or digital circuits.
Such as precision measuring equipment (voltmeter, power meter, oscilloscope, various analyzers).
Third, industrial control.
Single-chip microcomputer has the advantages of small size, strong control function, low power consumption, strong environmental adaptability, flexible expansion and convenient use. It can be used to form 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 lines, intelligent control of elevators, various alarm systems and computer networking form a secondary control system.
Fourth, household appliances.
Single-chip microcomputer control is widely used in household appliances, from rice cookers, washing machines, refrigerators, air conditioners, color TVs and other audio-visual equipment to electronic scales and white goods.
Verb (abbreviation for verb) network and communication
Modern single-chip computers generally have communication interfaces, which can communicate with computers conveniently, providing excellent material conditions for the application between computer networks and communication equipment. Communication equipment has basically realized the intelligent control of single chip microcomputer, from mobile phone, telephone, small program-controlled exchange, building automatic communication call system, train wireless communication, to mobile phone, trunking mobile communication, radio and so on, which can be seen everywhere in daily work.
The field of intransitive verb equipment
Single-chip microcomputer is also widely used in medical equipment, such as medical ventilator, various analyzers, monitors, ultrasonic diagnostic equipment, sickbed call system and so on.
Seven, modular system
Some special single-chip microcomputers are designed to achieve specific functions, so that they can be used in various circuits in a modular way without the need for users to understand their internal structure. For example, music integrated single chip microcomputer, seemingly simple function, miniature in pure electronic chip (different from the principle of tape drive), needs complex computer-like principle. For example, music signals are stored in digital form in a memory (similar to a ROM), read by a microcontroller and converted into analog music electrical signals (similar to a sound card).
In large-scale circuits, this modular application greatly reduces the size, simplifies the circuit, reduces the damage and error rate, and is also convenient for replacement.
Eight, automotive electronics
Single-chip microcomputer is widely used in the field of automobile electronics, such as engine controller in automobile, intelligent electronic controller of automobile engine based on CAN bus, GPS navigation system, abs anti-lock braking system, braking system, tire pressure detection and so on.
In addition, single-chip microcomputer is also widely used in industry and commerce, finance, scientific research, education, electric power, communication, logistics and national defense and aerospace.
