港口船舶尾气排放时空分析与可视化系统

Spatial-temporal analysis and visualization system for ship exhaust emission in port

针对港口船舶排放计算过程中所面临的数据密集型问题,为有效提高港口船舶尾气动态排放的计算和监管能力,设计研发一种船舶尾气排放时空分析与可视化系统.首先,综合介绍了系统的设计思路及整体架构;其次,分别对系统的几个主要模块的功能及其实现过程进行详细阐述;最后,以深圳港口岸为实验区域,开发了深圳港船舶排放监测监管原型系统,分别以单船排放和区域排放结果可视化为例对提出方案进行实用性验证.结果表明,该系统能够提供船舶尾气动态排放的实时计算结果以及多尺度的船舶排放时空统计信息,并支持多样化的视觉表征,能够为管理者提供直观的港口水域船舶排放信息.

In view of the data-intensive problems in the calculation of ship emissions in ports,a spatialtemporal analysis and visualization system of ship emissions was designed and developed in order to improve the calculation and monitoring efficiency of ship exhaust dynamic emission in ports.Firstly,the design idea and overall framework of the system was introduced comprehensively.Then,the function and realization process of several main modules of the system were described in detail.Finally,taking Shenzhen port as the experiment area to develop a prototype system for ship emission monitoring and supervision,and taking the visualization of single ship emission and regional emission results as examples to verify the practicability of the proposed scheme in this paper.Results show that the system can provide realtime calculation results of ship exhaust dynamic emission and multiscale ship emission spatialtemporal statistical information,and support diversified visual representation,which can provide intuitive ship emission information for managers in port waters.
