Research On Data Acquisition And Processing Technology Of North-Seeker

Gyro azimuth instrument and gyro compass are widely used in all kinds of vessels as the independent navigation equipment, and provide reliable heading basis for the vessel navigation, they also are used as the azimuth basis of autopilot and navigation plotter. Because of the limitation of Gyro azimuth instrument and gyro compass, they cannot used as the navigation equipment of the military speed boat.Then we put forward a project of a small north-seeker based on PC /104 for vessel. The system is constructed with a special and neat mechnical scheme, it owns the ability of quick north seeking, and it also has the superiority of anti execrable environment,small volume,less cost, the most important is that the system meets with the combat demand,has two kinds of working state with comprass and azimuth instrument,can both seek north in resting base and dynamic base, seek north mall in 6 minntes.This text according to the total project of the north-seeker, design and realize the the hardware electric circuit of the data acquisition and collecting sub-system for north-seeker according to PC/104,according to the function of the north-seeker to complete the design of the data acquisition and processing software,and carried on a research to the error analysis and its compensate.The result of experiment indicated that the hardware and software design of the data acquisition and collect for north-seeker satisfy the design index request,can guarantee to north-seeker seeking north quickly.
