The level attitude detection plays an important role in the control and measurement fields.The real-time high-precision dynamic level attitude detections of the carries are the actual demands of the technical market and a challenge of the research work.Thus a high-precision level attitude dynamic detection sensor system has been designed.It is a combination of micro-machined inclinometers,micro-machined gyroscopes and the signal processing circuits.The proposed scheme uses the gyroscope to compensate the various acceleration interference brought about by the carrier in traveling,thus the high-precision dynamic level attitude detection of the traveling carrier can be realized.The overall scheme design of the system,the hardware design of its components such as the power conversion,the pre-processing of sensing signals,analog-to-digital conversion,the signal processing and the system output as well as the software design method have been presented in this paper.A sensor system was assembled and tested after the system design was carried out.The results showed that the system design was able to meet the real-time high-precision demand of the level attitude detection of the moving carriers.
