摘　　要：为实现磁罗经自差自动校正的目的,在总结国内外磁罗经自差校正方法的基础上,通过理论研究和实践探索,提出磁罗经自差自测自校系统的设计方案,并保持磁罗经原有的优点。系统利用船舶在航状态时的航向,自动调整磁棒和软铁片(球)的位置,完成磁罗经自差校正过程,并达到规范所要求的精度。提出的磁罗经自差校正方法是一种高效的智能方法,省工省时省油,能确保船舶航行安全。In order to realize the self-correction of the magnetic compass deviation,based on the summary of the correction methods of the magnetic compass deviation at home and abroad,the design scheme of the self-detection and self-correction system of the magnetic compass deviation is put forward through theoretical research and practical exploration,where the original advantages of the magnetic compass are maintained.According to the course of a ship in the navigation state,the system can automatically adjust the positions of the magnetic rod and the soft iron(ball),complete the correction process of the magnetic compass deviation,and achieves the precision required by the specification.The proposed method is an efficient and intelligent method for the correction of magnetic compass deviation,which saves labors,time and fuel,and can ensure the navigation safety of ships.
