摘要
受到信号强度的限制,致使传统的舰船自主导航系统存在导航容错率低的问题,为此在弱信号环境下,利用单片机设备实现对舰船自主导航系统的优化设计。在传统硬件系统的基础上,安装单片机设备,并与滤波器相连,抑制弱信号中的噪声信号,并调整硬件连接电路。在硬件设备的支持下,检测弱信号并提取其中的有效信息,结合舰船的当前位置与目标位置生成导航路线,并实现对导航数据的动态更新。通过对系统的测试发现,与传统系统相比导航位置与设定位置的偏差更小,容错率提高了59.6%。
Due to the limitation of signal strength,the traditional navigation system has the problem of low fault tolerance.Therefore,in the weak signal environment,the single-chip microcomputer is used to optimize the design of the navigation system.On the basis of the traditional hardware system,the single-chip microcomputer equipment is installed and connected with the filter to suppress the noise signal in the weak signal and adjust the hardware connection circuit.With the support of hardware equipment,weak signals are detected and the effective information is extracted.The navigation route is generated by combining the current position and target position of the ship,and the dynamic update of navigation data is realized.Through the test of the system,it is found that compared with the traditional system,the deviation between the navigation position and the set position is smaller,and the fault tolerance rate is increased by 59.6%.
