Application of single chip microcomputer

At present, 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. Single-chip microcomputer is widely used in intelligent management and process control fields such as instruments, household appliances, medical equipment, aerospace and special equipment. , can be roughly divided into the following categories: 1 The application of single chip microcomputer in intelligent instruments has the advantages of small volume, low power consumption, strong control function, flexible expansion, miniaturization and convenient use. It is widely used in instruments and meters, and can realize functions such as voltage and power by combining with different types of sensors. 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 (power meter, oscilloscope, various analyzers). 2. Application in industrial control A single chip microcomputer can form various control systems and data acquisition systems. For example, a smart tube chip in a factory assembly line.

Management, elevator intelligent control, various alarm systems, and computer networking to form a secondary control system. 3. Application in household appliances It can be said that the current household appliances are basically controlled by single chip microcomputer, ranging from rice cookers, washing machines, refrigerators, air conditioners, color TVs and other audio-visual equipment to electronic scales. 4. Application in computer network and communication field. 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. Now the communication equipment has basically realized the intelligent control of single chip microcomputer, from mobile phones, telephones, small program-controlled exchanges, building automatic communication call systems, train wireless communication, to mobile phones, trunking mobile communication, radios, etc., which can be seen everywhere in daily work. 5. Application of Single Chip Microcomputer in the field of medical equipment Single chip microcomputer is also widely used in medical equipment, such as medical ventilators, various analyzers, monitors, ultrasonic diagnostic instruments, sickbed call systems, etc. 6. Modularization is applied to various large electrical appliances. Some special single-chip microcomputers are designed to achieve specific functions, so that they can be modularized in various circuits without users knowing their internal structures. 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. 7. Application of Single Chip Microcomputer in the field of automobile equipment 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 and braking system. In addition, single-chip microcomputer is widely used in industry and commerce, finance, scientific research, education, national defense and aerospace.
