雷达和自动识别系统(Automatic Identification System,AIS)是配备最多的2类安全助航设备,在海上船舶导航领域发挥着不可替代的作用。由于雷达与AIS提供的信息具有良好的互补性和冗余性,二者融合可以改善探测性能、提高导航系统的精度和可靠性,是近年来海上导航技术的重点发展方向。本文首先介绍雷达/AIS信息融合技术,接着总结其国内外研究现状,并重点阐述航迹关联和信息融合两项关键技术的研究现状,最后提出雷达/AIS信息融合技术发展中待解决的问题,并展望其未来发展趋势。 相似文献

船舶交通管理系统(VTS)在提高船舶航行效率、保障船舶航行安全等方面具有重要作用。传统的船舶交通管理系统采用雷达等传感器作为基本检测手段,受到雷达探测距离和精度等技术条件的限制,在船舶定位、导航等方面存在一定的缺陷。随着互联网技术和信息融合技术的发展,雷达探测器与船舶自动识别系统(AIS)相结合的船舶交通管理系统成为研究的热点。船舶自动识别系统(AIS)结合了信息技术、互联网技术和通信技术,对船舶的航向、航迹、航速等信息采集和处理,并利用VHF发送给信号覆盖区域内的其他船只。本文针对我国内河航运船舶的交通管理系统,研究了AIS与雷达信号的信息融合算法、航迹关联算法等,对提高内河船舶交通管理系统的性能有重要的作用。 相似文献

港口设备安全管理工作的目的,就是要保障设备技术性能完好和运行安全.设备安全性能是由设备设施的配置来保障.随着设备使用年限的增加,部分安全设施老化失灵、金属钢结构的局部失稳或结构疲劳而产生的裂纹、外部环境影响而产生的腐蚀、供电或控制线路老化等,严重影响着港口生产和安全.港机设备的安全管理工作是港口安全和设备管理工作的重要内容.近年来,宁波港始终把装卸设备的安全管理工作作为工作重点来抓,取得了较明显的成效. 相似文献

The objective of this paper is to analyse the relative competitiveness of the neighbouring container ports of Shanghai and Ningbo in China and to develop a view of the likely future outcome of the competition between them. After assessing the demand for their services within what is hypothesized as a shared hinterland, current supply and future expansion plans are detailed and considered within the two ports’ wider development strategies. The relative competitiveness of the two ports is then evaluated on the basis of price and quality of service, as embodied within the concept of generalized cost as incurred by customers. A critical political dimension is a necessary element of this analysis. It is concluded that continued economic development in the hinterland, central government policies on regional development and China's accession to the World Trade Organization (WTO) will all contribute to growing demand for port services. However, Ningbo will continue to gain greater market share as the result of advantages in its natural endowments (particularly depth of water), price (especially in terms of recovering the cost of capacity expansions) and quality of service improvements that are predicted to emerge as the result of currently planned enhancements to inland transport infrastructure and logistical systems. 相似文献
