Measuring instrument

Measuring instruments are the third party standards required for measuring in order to obtain some attribute values of the target. Measuring instruments generally have scales, volumes and other units.

1. Classification of measuring instruments

The basic contents of the concept of measuring instrument include: precision, error, measuring standard equipment, length measurement, angle measurement, shape measurement, and traditional optical instruments. Application in precision measurement, etc. The common types of measuring instruments are electronic measuring instruments. Quadratic: automatic image, manual influence; CMM: manual, motor driven, CNC.

2. Common applications of measuring instruments

Electronic measuring instruments have a unique strategic industry. Its own development has a very obvious impact on the development of the entire national economy, especially the electronic information industry. The market of electronic measuring instruments in China is huge and the demand is large. Electronic measuring instruments play a vital role in the development of electronic information industry. The development of domestic electronic measurement technology and electronic measurement instruments is rapid, covering all walks of life. First, the basic theoretical research of electronic measurement technology: new testing theory and method research, artificial intelligence theory research, frequency based traceability and standard acquisition method research, new measurement and control bus and system structure research The research and formulation of measurement and instrument standards are the focus of theoretical research in the future. Second, the development of electronic measurement and measurement technology: the fast developing technologies include advanced measurement and control bus technology, new digital signal processing technology, new comprehensive testing and fault diagnosis technology, new optical frequency standard and precision time-frequency testing technology. The third and second types of important electronic measuring instruments: an important development direction of vector network analyzer is to build automatic measurement technology and automatic test system with vector network analyzer as the core; In addition, vector network analyzer has gone out of the application field of traditional linear network, and plays an important role in the test and analysis of nonlinear and high-power networks. Modulation domain analyzer is the only technology that can directly measure the jitter that changes with time in communication transmission, especially in the field of military electronic testing. Shanghai Quanaifeng Precision Measuring Instrument Co., Ltd. is a professional agency of Japan Sanfeng Measuring Tools and Gauges, Japan SK Gauges and other professional companies. For a long time, it has a high reputation in the field of tool and gauge sales. Fourth, the development of modern production technology of electronic measuring instruments: the design and production level of instrument products is an important symbol to measure a country's scientific, technological and industrial foundation and industrial capacity, which runs through the whole production process and life cycle of products. In the future, attention should be paid to solving the problems of product design and process supervision mode in the research of instrument production technology, studying new instrument devices, developing high-precision and high-quality quality inspection equipment for special components, parts and components of instruments and meters, and the whole machine, studying virtual test verification and engineering verification technology, studying advanced production processes and processes, and studying stability New evaluation methods of reliability, maintainability and testability, and standardized certification system of products. Fifth, integrated test system of electronic measuring instruments: integrated test should focus on the system optimization research of integrated test system, the research on the unity and integrity technology of measurement and control system, the research on sensor information processing and multi-sensor data fusion technology, and the research on distributed network interconnection, triggering, synchronization and other technologies of field test in large areas, And the research of reconfigurable measurement and control system technology based on synthetic instruments and systems. China's electronic measuring instruments are now in the second development opportunity since the founding of New China. Mainly due to the development of China's economy, there have been two changes in China's economy: one is the upgrading of industries, and the other is the independent innovation of industries. An industry needs electronic measuring instruments to complete the selection of raw materials, the monitoring of production process, the testing of products, and the operation of the industry. Therefore, electronic measuring instruments shoulder the historical mission of upgrading and independent innovation of other industries.

3. Development history of measuring instruments

Scholars and navigators know very well that if the position of celestial bodies can be accurately measured on the sea surface, then sailors can know their latitude with relative certainty. To do this, precise measuring instruments are needed. Ptolemy once described the astrolabe (also called astrometer). The larger ones are used in observatories and the smaller ones are used on ships. The use of the astrolabe requires the cooperation of three people - one grabs the thumb ring on the astrolabe, one aims, and the other reads the results on the dial. When the ship shakes violently, the result is naturally not very accurate. Whenever possible, sailors would go ashore to survey. Ancient astronomers used a cross ruler to measure the latitude of stars, and later sailors also used it in navigation. This instrument consists of a ruler and a cross ruler, with the lower end of the cross ruler placed in a horizontal position. While observing the celestial body along the ruler, slide the cross ruler until it touches the object (sun or star) in your field of vision, and then read the degree on the ruler. This instrument can be operated by only one person. Both the astrolabe and the cross ruler require the observer to observe the sun directly. In sunny days, too strong light will make observation impossible. In order to solve this problem, John Davis, an English captain and navigator, invented the back scale. It is made of a ruler and a sliding crossbar. When observing, the observer first turns his back to the sun, and then slides the crossbar until it casts a shadow on the small disk in front of him. In this way, the observer can observe the horizon. John Davis also invented the quadrant with the help of Edward Wright, a mathematician from Cambridge. There is an eyepiece on the crossbar of this instrument, through which the observer can observe the horizon and the reflected sun. Pierre Burger, a hydro geographer in Kloicik, made further improvement on the object limit instrument. The improved quadrant enables the observer to see the sun setting on the horizon through the eyepiece. John Hadley in England invented the octave and tried it out for the first time in 1732. It consists of a reflecting telescope and an alcohol level. This instrument is more accurate than any other instrument used at sea before.
