摘要
针对潮汐传播呈线性变化,水域如何实现高密度实时水位的获取问题,详细阐述了技术实现需要的资源及涉及的关键技术与数学模型。运用实例介绍了在珠江口航道水域如何获取高密度实时水位的主要技术设计内容,并对设计获取的潮位精度进行了数据验证,结果表明中误差控制在7cm以内。最后对水域高密度实时水位及其获取技术的应用前景进行了展望。
Aimed at the problem of how to get the real-time water level with high density in the tidal propagation linearly waters,this paper illustrates in detail the needed resources key technologies and mathematical models for technical realization. It is introduced through examples how to get the main technical design contents of real-time water level with high density in Pearl River Estuary channel waters,and the tidal data accuracy is verified. The results show that the error is within 7 cm. Finally,we look forw ard to the application aspect of the real-time water level with high density and acquisition technologies.
