Microcontroller is widely used in the field of instrumentation, household appliances, medical equipment, aerospace, intelligent management of special equipment and process control, etc., which can be roughly divided into the following categories:
1.In the application of intelligent instrumentation
Microcontroller has the advantages of small size, low power consumption, strong control functions, flexible expansion, miniaturization and ease of use. Widely used in instrumentation, combined with different types of sensors, can be realized such as voltage, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, elements, pressure and other physical measurements. The use of microcontroller control makes instrumentation digital, intelligent, miniaturized and more powerful than with electronic or digital circuits. For example, precision measurement equipment (power meter, oscilloscope, various analyzers).
2. Application in industrial control
With microcontroller can constitute a variety of control systems, data acquisition systems. For example, intelligent management of factory assembly lines, intelligent control of elevators, various alarm systems, and computer networking to form a secondary control system.
3. Application in household appliances
It can be said that nowadays all household appliances are basically controlled by microcontroller, from the rice cooker, washing machine, refrigerator, air-conditioner, color TV, other audio-video equipment, and then to the electronic weighing equipment, a variety of ubiquitous.
4. Application in the field of computer networks and communications
Modern microcontroller generally has a communication interface, can easily communicate with the computer data, for the application of computer networks and communications equipment provides excellent material conditions, now the communication equipment basically realize the intelligent control of the microcontroller from the cell phone, telephone, small program-controlled switches, buildings, automatic communication call systems, trains, wireless communication equipment, and so on. Automatic communication call system, train wireless communication, and then to the daily work everywhere in the cell phone, trunking mobile communication, radio intercom and so on.
5. Microcontroller in the field of medical equipment
Microcontroller in the medical equipment in a wide range of uses, such as medical respiratory machine, a variety of analyzers, monitors, ultrasound diagnostic equipment and bed call system and so on.
6. In a variety of large-scale appliances in the modular application of certain special microcontroller designed to achieve a specific function, so that in a variety of circuits in the modular application, without requiring the use of personnel to understand its internal structure. Such as music integrated microcontroller, seemingly simple functions, microscopic in a purely electronic chip (as distinct from the principle of the tape machine), you need to be complex similar to the principle of the computer. Such as: music signals in the form of digital stored in memory (similar to ROM), read by the microcontroller, converted to analog music electrical signals (similar to the sound card).
In large circuits, this modular application greatly reduces the size, simplifies the circuit, reduces damage, error rate, and facilitates replacement.
7. Microcontroller in the field of automotive equipment Microcontroller in automotive electronics is widely used, such as engine controllers in automobiles, CAN bus-based automotive engine intelligent electronic controllers, GPS navigation systems, abs antilock system, braking system and so on.
In addition, microcontrollers have a very wide range of uses in business, finance, research, education, defense and aerospace fields.
