Source: China Instrument Network Core Tip: Mobile phones are becoming more and more intelligent, and mobile customers’ terminals make the instrument industry have to look at the existing industry trends and move toward intelligence. Industries that don’t want to die need to be at the forefront of the times. Next, Ayi.com will share with you the development of smart instruments and mobile phones becoming more and more intelligent. Mobile customers’ terminals make the instrument industry have to look at the existing industry trends and move towards intelligence, and industries that don’t want to die need to go. At the forefront of the times, the following Ayinet will share with you the development of smart instruments and where the future will be intelligent:    Overview of the development of smart instruments in the 1980s, microprocessors were used in instruments, and the front panel of the instrument began to turn toward the keyboard With the development of industrialization, measurement systems are often connected via ieee488 bus. Personal instruments that are different from the traditional independent instrument model have been developed. In the 1990s, the intelligentization of instruments and meters was prominently manifested in the following aspects: the progress of microelectronics technology more profoundly affected the design of instruments and meters; the advent of dsp chips greatly enhanced the digital signal processing functions of instruments and meters; the development of microcomputers, Make instruments and meters have stronger data processing capabilities; the increase in image processing functions is very common; the vxi bus is widely used.   In recent years, the development of intelligent measurement and control instruments has been particularly rapid. A variety of intelligent measurement and control instruments have appeared in the domestic market, such as intelligent throttling flowmeters that can automatically perform differential pressure compensation, intelligent multi-stage temperature controllers that can perform program temperature control, and can achieve digital pid and various Intelligent regulators with complex control laws, and intelligent chromatographs capable of analyzing and processing various spectra. There are many kinds of intelligent measuring instruments in the world. For example, the dstj-3000 series of intelligent transmitters produced by Honeywell in the United States can perform composite measurement of the differential pressure value, and can automatically realize the temperature and static pressure of the transmitter body. Compensation, the accuracy can reach 0.1% fs; the 9303 ultra-high level meter of raca-dana company in the United States uses a microprocessor to eliminate the thermal noise generated by the current flowing through the resistor, and the measurement level can be as low as -77db; the United States fluke The 5520a super multi-function calibrator produced by the company uses three microprocessors inside, and its short-term stability can reach 1ppm, and the linearity can reach 0.5ppm; the digital self-tuning regulator produced by Foxboro Corporation in the United States adopts expert system technology. Like an experienced control engineer, the regulator can be tuned quickly according to on-site parameters. This kind of regulator is particularly suitable for control systems with frequent or non-linear changes in objects. Since this regulator can automatically adjust the adjustment parameters, the entire system can always maintain the best quality during the production process.  The development trend of smart instrumentation   Miniaturization   Micro-smart instrument refers to the integrated application of microelectronics, micromechanical technology, and information technology in the production of instruments, so that the instrument becomes a small, fully functional intelligent instrument. It can complete signal acquisition, linearization processing, digital signal processing, control signal output, amplification, interface with other instruments, and human interaction. With the continuous development of microelectronic machinery technology, micro-smart instruments continue to mature and their prices continue to decrease, so their application areas will continue to expand.   It not only has the functions of traditional instruments, but also can play a unique role in automation technology, aerospace, military, biotechnology, and medical fields. For example, it is currently necessary to measure several different parameters of a patient at the same time, and to control certain parameters. Usually, several tubes are inserted into the patient's body, which increases the chance of infection of the patient. The miniature intelligent instrument can measure multiple parameters at the same time. , And small in size, can be implanted in the human body, so that these problems can be solved.  Multi-function   Multi-function itself is a characteristic of intelligent instruments. For example, in order to design digital systems with a faster speed and a more complex structure, instrument manufacturers have manufactured function generators with functions such as pulse generators, frequency synthesizers, and arbitrary waveform generators. This multi-functional comprehensive product not only has higher performance (such as accuracy) than dedicated pulse generators and frequency synthesizers, but also provides better solutions for various test functions.  Artificial intelligence   Artificial intelligence is a brand-new field of computer applications, which uses computers to simulate human intelligence and is used in various aspects such as robots, medical diagnosis, expert systems, and reasoning proofs. The further development of intelligent instruments will contain a certain amount of artificial intelligence, which replaces part of the human brain work, so as to visually (image and color recognition), hearing (speech recognition and language comprehension), thinking (reasoning, judgment, learning and association) Have a certain ability in other aspects.  In this way, smart instruments can autonomously complete detection or control functions without human intervention. Obviously, the application of artificial intelligence in modern instrumentation enables us not only to solve a type of problem that is difficult to solve with traditional methods, but also to solve problems that cannot be solved with traditional methods at all. Integrate isp and emit technology to realize internet access (networked) of instrumentation system    With the rapid development of network technology, internet technology is gradually infiltrating the field of industrial control and intelligent instrumentation system design, realizing intelligent instrumentation system based on internet Communication capability and remote upgrade, function reset and system maintenance of the designed intelligent instrumentation system.  In-system programming technology (in-systemprogramming, isp technology for short) is the latest technology to modify, configure or reorganize software. It is the first proposed by Lattice Semiconductor Company to enable us to carry out the logic and functions of the device, circuit board or the entire electronic system at any time in every link in the product design and manufacturing process, even after the product is sold to the end user. The latest technology for configuration or reorganization capabilities. The isp technology eliminates some of the limitations and connection disadvantages of traditional technology, and is conducive to on-board design, manufacturing and programming. The isp hardware is flexible and easy to modify software, which is convenient for design and development. Because the ISP device can be processed on the printed circuit board (pcb) like any other device, the programming of the ISP device does not require a special programmer and a more complicated process, as long as it is carried out through a PC, an embedded system processor or even an internet remote network. Programming.   The emit embedded micro-Internet interconnection technology was proposed when the emware company founded eti (extend the internet) to extend the internet alliance. It is a way of connecting embedded devices such as single-chip microcomputers.
