Description

Technical Field

[0001] The utility model relates to the technical field of intelligent instruments, in particular to a protection device for intelligent instruments. Background Art

[0002] Intelligent instruments are based on microcomputers (single-chip microcomputers) and organically combine computer technology and detection technology to form a new generation of "intelligent instruments". With the continuous development of microelectronics technology and computer technology, the structure of instruments has undergone fundamental changes. With microcomputers (single-chip microcomputers) as the main body, computer technology and detection technology are organically combined to form a new generation of "intelligent instruments". Compared with the conventional measurement circuits of traditional instruments in terms of measurement process automation, measurement data processing and functional diversification, great progress has been made. Intelligent instruments can not only solve problems that are difficult or impossible to solve with traditional instruments, but also simplify instrument circuits, improve the reliability of instruments, and more easily achieve the goals of high precision, high performance and multi-functions. With the further development of science and technology, the degree of intelligence of instruments will become higher and higher. Intelligent instruments can not only accurately display a variety of physical quantities, but also have multiple functions such as transmission output, relay control output, communication, and data retention. Intelligent instruments and intelligent sensors are generally used in fieldbus systems. Such instruments and sensors are embedded with communication modules and control modules, which can complete data acquisition, data processing and data communication functions.
