| Abstract: | This paper described a design solution of two-dimensional and highprecision digital inclinometer based on thermal accelerometer.Starting from mathematical model,it calculated the algorithm of angle measurement.Outside interference could be minimized in the method of suppression by hardware and filtering by software.And it solved the problem that zero was drifting when large angles were measured.Results show that the instrument can be used for various high-precision angle measurement. |
