But online control aspect, because the putation fuselage is in the system, therefore has the volume to the puter small, the power loss small, the cost low, the price inexpensive as well as the control function strong and so on the requests, to these requests really it may be said must belong to the monolithic integrated circuit. At present the monolithic integrated circuit seeps each domain which lives to us. which domain is nearly very difficult to find not to have the monolithic integrated circuit trail. The missile navigation equipment, on the airplane each kind of measuring appliance control, the puter network munication and the data transmission, the industrial automation process realtime control and the data processing, the widespread use each kind of intelligent IC card, the civil luxury car safety system, the videocorder, the camera, the pletely automatic washer control, as well as program control toy, electronic pet and so on, these cannot leave the monolithic integrated circuit. Say nothing of automatic control domain robot, intelligent measuring appliance, medical instrument.Also known as singlechip MCU (Microcontroller), because it was first used in the field of industrial control. Only by the singlechip CPU chip developed from the dedicated processor. The design concept is the first by a large number of peripherals and CPU in a single chip, the puter system so that smaller, more easily integrated into the plex and demanding on the volume control devices. INTEL the Z80 is one of the first design in accordance with the idea of the processor, From then on, the MCU and the development of a dedicated processor parted ways.Early singlechip 8bit or all of the four. One of the most successful is INTEL39。s 8031, because the performance of a simple and reliable access to a lot of good praise. Since then in 8031 to develop a singlechip microputer system MCS51 series. Based on singlechip microputer system of the system is still widely used until now. As the field of industrial control requirements increase in the beginning of a 16bit singlechip, but not ideal because the price has not been very widely used. After the 9039。s with the big consumer electronics product development, singlechip technology is a huge improvement. INTEL i960 Series with subsequent ARM in particular, a broad range of applications, quickly replaced by 32bit singlechip 16bit singlechip highend status, and enter the mainstream market. Traditional 8bit singlechip performance has been the rapid increase in processing power pared to the 8039。s to raise a few hundred times. At present, the highend 32bit singlechip frequency over 300MHz, the performance of the mid9039。s close on the heels of a special processor, while the ordinary price of the model dropped to one . dollars, the most highend models, only 10 . dollars. Contemporary singlechip microputer system is no longer only the baremetal environment in the development and use of a large number of dedicated embedded operating system is widely used in the full range of singlechip microputer. In PDAs and cell phones as the core processing of highend singlechip or even a dedicated direct access to Windows and Linux operating systems.In humanity39。s each production activity and scientific experiment, in order to understand with the grasping entire process progress and the final output, needs frequently carries on the inspection and the survey to each kind of basic parameter or the physical quantity, thus obtains the essential information, and by it achievement analysis judgment and policymaking examination technology and the sensor are people in order to was measured the object contains the information carries on a series of technical measure which the qualitative understanding and quota grasping adopts.The modern of science and technology fast development causes the human society to enter the information age, mainly will depend upon in the information age people39。s social activity to the information resource development and the gain, the transmission and processing, but the sensor will be in head of the automatic detection and the control system, will be the sensation, the gain and the examination information window。 The sensor belongs to the object of study and the observation and control system connection installment, all scientific research and the production process must gain the information, all must transform through it for easy to transmit and the processing electrical the sensor status and the function is extremely important.Sensor function quite Yu Ren five system automatic routine, the intellectualized degree are higher, the system the level of dependency is bigger to the sensor, the sensor plays the decisive role to the system , domestic and foreign all lists as the sensor technology the most advanced technique. The sensor application sensor application domain involves the machine manufacture, the mercial run control, the automobile electronic products, the correspondence electronic products, the expense electronic products and the special purpose equipment and so on.(1) special purpose equipmentThe special purpose equipment mainly includes
