基于嵌入式技术的舰船捷联控制系统基准设计

The basic design of ship strapdown control system based on embedded technology

舰载武器射击精度受到战场环境和气候条件的影响较为显著,舰船的主惯导系统无法解决不同位置武器的实时姿态测量问题。本文对分立式舰载捷联基准系统的结构及工作流程进行研究,提出了一种基于ARM+DSP嵌入式技术的舰船捷联控制系统基准设计方案,设计硬件系统结构,分析闭环光纤陀螺的结构和工作原理,最后对系统进行俯仰角和横摇角的测试,测试结果表明,系统具有较高的测量精度和稳定性。

The shooting accuracy of shipborne weapons is significantly affected by the battlefield environment and climate conditions,and the main inertial navigation system of a ship can not solve the problem of real-time attitude measurement of weapons at different positions.In this paper,the structure and workflow of the separate shipborne strapdown reference system are studied,and a reference design scheme of the ship strapdown control system based on ARM+DSP embedded technology is proposed.The hardware system structure is designed,and the structure and working principle of the closed-loop fiber optic gyroscope are analyzed.Finally,the pitch Angle and roll Angle of the system are tested.The system has high measuring accuracy and stability.
