摘要
为解决RTK船舶导航系统定向能力较差、目标定位精度较低等问题,设计基于物联网的高精度船舶导航系统。通过物联网传感器电路设计、导航信息采集模块设计2个方面,完成新型导航系统的硬件运行环境搭建。在此基础上,按照导航数据采集与预处理、数据精度解算、导航任务分配的物理操作流程,完成新型导航系统的软件运行环境搭建,结合硬件执行条件,实现基于物联网高精度船舶导航系统的顺利运行。对比实验结果表明,与RTK导航系统相比,应用新型高精度导航系统后,船舶定向能力得到稳定提升,目标定位精度的最大值也不再低于理想极值85.21%。
In order to solve the problems of poor orientation ability and low target positioning accuracy of RTK ship navigation system,a high precision ship navigation system based on Internet of Things is designed.Through the design of sensor circuit and navigation information acquisition module of the Internet of Things,the hardware operation environment of the new navigation system is built.On this basis,according to the physical operation flow of navigation data acquisition and pre-processing,data precision calculation and navigation task assignment,the software operation environment of the new navigation system is built,and the smooth operation of the high-precision ship navigation system based on the Internet of Things is realized by combining the hardware execution conditions.The experimental results show that,compared with RTK navigation system,the ship orientation ability has been steadily improved with the application of the new high-precision navigation system,and the maximum target positioning accuracy is no longer lower than the ideal extreme value of 85.21%.
