北斗定位在内河疏浚船舶管理中的研究与应用

Research and application of BDS in inland dredging ships management

为解决内河船舶AIS定位频率过低、精度较差等问题,采用新一代北斗定位技术进行船舶定位,通过自主搭建数据的采集、解析和存储服务,将船舶定位精度提高到亚米级,数据传输频率提高到秒级。通过结合智能自动算法和GIS空间分析技术,开展业务层应用研究,如实时施工情况可视化、电子围栏预警、挖运吹工单自动填报等,减少了人工操作,实现了内河疏浚船舶管理中的精细化、数字化、智能化的管理。北斗定位技术在内河疏浚船舶管理中的成功应用可为同类工程实现自动化管理提供参考。

To solve the problems of low positioning frequency and poor accuracy of inland ships’ AIS data,the new generation of BeiDou Navigation Satellite System(BDS)is used for ship positioning.Through self-built data collection,analysis and storage services,the positioning accuracy has been improved to sub-meters and the data transmission frequency has been increased to seconds.Combined with automatic algorithms and spatial analysis technology in GIS,we carry out business applications of BDS,such as real-time dredging construction status visualization,electronic fence warning,automatic filling work orders,etc.,which reduce manual operations on the management of inland dredging ships and achieve the goal of refined,digital and intelligent management.The result is a successful application of BDS in the management of inland dredging ships,and it may serve as reference for similar projects to build an automated management system.
