Research and application on cloud tide service based on virtual tide station technology

针对疏浚工程施工对高质量、智能化实时水位信息服务的需求,设计并实现了可服务于疏浚工程施工活动的北斗实时水位信息服务云平台系统。系统采用了后端、计算存储中心和前端三层结构,使用北斗通信链路将三层结构连接起来,系统可根据施工船舶的实时动态位置,应用区域高精度潮汐模型和区域高精度余水位模型,虚拟一个目标船舶专用的虚拟水位站,并根据该虚拟水位站的预报水位和余水位计算实时水位数据,通过北斗通信链路将实时水位数据传输至施工船舶。系统有效提升了实时水位信息服务的精度、可靠性和智能化水平,可为疏浚工程项目提供稳定可靠的实时水位数据服务。

In response to the demand for high-quality and intelligent real-time tide information services in dredging engineering construction,a Beidou real-time tide level information service cloud platform system has been designed and achieved,which can serve surface and underwater construction activities.The system adopts a three-tier structure of the back end,calculation storage center and front end,and uses the Beidou communication link to connect the three-tier structural join.The system can use the regional high-precision tide model and regional high-precision residual water level model to create a virtual tide station dedicated to the target ship according to the real-time dynamic position of the construction ship,and calculate the real-time tide data of the virtual tide station according to the predicted tide and residual water level.The real-time tide data is transmitted to the construction ship through the Beidou communication link.The system effectively improves the accuracy,reliability and intelligence level of real-time tide level information service,and can provide stable and reliable real-time tide level data service for dredging projects.
