Embodiment Construction

[0022] In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described below.

[0023] An AIS-based calculation method for the water depth utilization rate of coastal waterways according to the present invention aims to consider the water depth condition of the target area and the draft characteristics of the water depth utilization subject in the quantitative index of water depth utilization status, so that the quantitative index can be more reasonable and intuitive Characterize the water depth utilization status of coastal waterways, and then provide corresponding guidance for port waterway dredging. The invention is mainly composed of four parts: AIS data processing, water depth utilization ratio quantification calculation sample determination, target area model construction, and water depth utilization ratio quantification model.

Abstract

The present invention discloses a nearshore channel depth utilization rate calculation method based on an AIS. The method comprises four parts consisting of AIS data processing, determination of depth utilization rate quantitative calculation samples, construction of a target area model and construction of the depth utilization rate quantitative model. The method employs a ratio of ship draught in an AIS message and the sea chart depth in a target area as the most basic quantification index of the channel depth utilization condition. The index is compared to the current index, the depth condition of the target area and the ship draught features of the depth utilization main body are fully considered to reasonably and visually represent the nearshore channel depth utilization condition so as to provide corresponding guidance for the port and channel dredging.

Description

technical field [0001] The invention relates to the field of dredging and maintenance of near-shore waterways, and more specifically, relates to an AIS-based calculation method for water depth utilization ratio of near-shore waterways. Background technique [0002] In order to ensure the safety of ships entering and leaving ports, it is usually necessary to carry out regular or irregular maintenance on coastal waterways. Regardless of whether the water depth dynamic maintenance method or the water depth static maintenance method is adopted, factors such as the silting speed, design water depth and design navigable water depth are fully considered when determining the dredging cycle. Here, when determining the dredging period, the factor of actual water depth utilization can be introduced to further improve the economic benefit ratio. However, there are currently few methods for estimating water depth utilization in coastal waterway areas, and there are also few indicators f...
