Smart Time-grating Displacement Sensor System Motivated By Electricity

Time-grating displacement sensor is a new displacement sensor. The research for it is a creative work that has far-reaching significance. Compared with the traditional grating sensors,time-grating displacement sensor has some marked advantages such as simple structure and manufacture crafts, strong resistance for interference, low cost and high intelligence, which make it has satisfactory market prospect.Smart time-grating displacement sensor system mostly consists of field typed time-grating displacement sensor motivated by electricity and virtual displacement testing instrument. It is suitable for precise displacement testing.The thesis introduces the components and combination principle of the whole sensor system, then based on the theory of time-space coordinate transformation and field typed motive coordinate system, emphatically demonstrates the research & development process of circuit and programs in light of the characteristics of smart sensor, and illustrates the design process of virtual displacement testing instrument. At last, the author looks forward to the future research of the time-grating displacement sensor system and puts forward the aim of intemetlized smart time-grating displacement Sensor.
