【正文】 was. Therefore, the MCU learning, development and application of the large number of puter applications and intelligent control of the scientists, engineers. SCM is widely used in instruments and meters, household appliances, medical equipment, aerospace, specialized equipment, intelligent management and process control fields, roughly divided into the following several areas: 1. In the application of Intelligent Instruments SCM has a small size, low power consumption, controlling function, expansion flexibility, the advantages of miniaturization and ease of use, widely used instrument, bining different types of sensors can be realized Zhuru voltage, power, frequency, humidity, temperature, flow, speed, thickness, angle, length, hardness, elemental, physical pressure measurement. SCM makes use of digital instruments, intelligence, miniaturization, and functionality than electronic or digital circuits more powerful. Such as precision measuring equipment (power meter, oscilloscope, various analytical instrument). 2. In the industrial control application With the MCU can constitute a variety of control systems, data acquisition system. Such as factory assembly line of intelligent control 3. In Household Appliances can be said that the appliances are basically using SCM, praise from the electric 11 rice, washing machines, refrigerators, air conditioners, color TV, and other audio video equipment, to the electronic weighing equipment, varied, and omnipresent. 4. In the field of puter works and munications applications MCU general with modern munication interface, can be easy with the puter data munication, working and munications in puter applications between devices had excellent material conditions, are basically all munication equipment to achieve a controlled by MCU from mobile phone, telephone, miniprogramcontrolled switchboards, building automated munications call system, train radio munication, to the daily work can be seen everywhere in the mobile phones, trunked mobile radio, walkietalkies, etc.. 5. Microputer in the field of medical device applications SCM in the use of medical devices is also quite extensive, such as medical respirator, the various analyzers, monitors, ultrasound diagnostic equipment and hospital beds, etc. call system. 6. In a variety of major appliances in the modular applications Designed to achieve some special single specific function to be modular in a variety of circuit applications, without requiring the use of personnel to understand its internal structure. If music integrated single chip, seemingly simple function, miniature electronic chip in the (the principle is different from the tape machine), you need a puter similar to the principle of the plex. Such as: music signal to digital form stored in memory (like ROM), read by the microcontroller, analog music into electrical signals (similar to the sound card). In large circuits, modular applications that greatly reduce the volume, simplifies the circuit and reduce the damage, error rate, but also easy to replace. 7. Microcontroller in the application field of automotive equipment SCM in automotive electronics is widely used, such as a vehicle engine controller, CAN busbased Intelligent Electronic Control Engine, GPS 12 navigation system, abs antilock braking system, brake system, etc. In addition, the MCU in business, finance, research, education, national defense, aerospace and other fields has a very wide range of applications.
