Study On The Increment Implementation Method For Absolute Time-grating Displacement Sensor

As one of three cores in information technology, sensor-technology synthesizes knowledge and technologies in the field of physics, chemistry, biology, electronics & microelectronics, exact mechanics, exact machining, experimentation, etc. It will become the peak of renovation & progress for the high and fashionable technologies. Outside, sensor-technology is granted as the key of progress of modern high technologies. Inside, sensor-technology has been listed into pivotal field of high& fashionable technologies from 1980s. With the tide of progress of modern technologies, it provides a good chance for our country to accelerate research & development for newly next type of sensors, and diminish the gap of technological capability with the developed countriesTime-grating in the circular field type based on the TST method is a newly type of intelligent angle displacement sensor developed independently by our scientists, which not only has high precision, high performance-price ratio, strong adaptability, but also has no mark problem occurring in process of manufacturing traditional grating sensor. Undoubtedly, time-grating in the field type has a flourishing perspective. However, the toughest problem which cumber application of time-grating at the beginning of practicality is not technique barrier but no matchable numeric controlling devices or upper equipments. Because of this reason, according to displacement increment implementation method of increment grating, increment implementation method for time-grating in the field type is brought forward and a controlling circuit module is also provided aiming at numerical controlling device of incremental grating. Increment implementation method of time-grating has effectively resolved the problem on data conversion and transmission between time-grating in the field type and numerical controlling device of increment grating, and accomplished data compatibility.Increment implementation method and implementation of time-grating in the field type are main content in this paper, including:NO.1 Analyzing work theory and displacement increment implementation method of increment grating.NO.2 Introducing basic theory of time-grating in the field type—TST method, work principle and characteristics, and proposing increment implementation method of time-grating in the field type according to displacement increment implementation...
