Micro azimuth-level detector based on micro electro-mechanical systems and a method for determination of attitude

摘要

This present invention is subjected to the field of instrument & measurement technology based on Micro Electro-mechanical Systems (MEMS). A micro azimuth-level detector comprises multi-sensors (triaxial silicon accelerometers with the processing circuit and triaxial silicon magnetometers with the processing circuit), A/D converter for converting the analog signals of the sensors to the digital signals, microprocessor in which the signal-processing and attitude computation are carried out, RS-232 for connecting the microprocessor with PC, and Operation-Display interface. An attitude computation method uses the Orientation Cosine Conversion of the earth's gravity and magnetic field.
