摘要：In production and scientific research, the acquisition of over ground or underground buildings' attitude parameters, including inclination angle, rotation angle and azimuth angle, is necessary. The metrical principle of each parameter has been introduced in this thesis, and also A complete measuring system has been designed. The FLC3-70 is chosen as the magnetic sensor and MMA7260Q as the acceleration of gravity sensor. Data logging is composed of analog multiplexer and analog-to-digital converter ADS8322, while single chip microcomputer AT89C52 and the serial interface RS485 function as the control core of this system. The supervise software mainly consists of four parts, data logging, data-filtering, data processing and operation and communication module with PCs. The system, which is simple in structure but commonly used, is tested well in underwater devices' attitude-measuring.
