海上安全信息是船舶航行及作业安全的重要保障。VTS管辖水域通常船舶交通流密集、生产繁忙,为更好地满足船舶信息需求、维护辖区水域安全,VTS中心开始在传统人工服务手段的基础上探索实现海上安全信息的自动播发。然而,目前VTS人员对于VHF自动播发语音信息的性质存在认知差异,自动播发系统的使用存在较大的随意性。该文对VHF自动播发语音信息的性质、VHF海上安全信息自动播发系统应用需求及应用现状进行了分析,在此基础上提出了相关工作建议。 相似文献

AIS是运用了先进的船舶导航技术、数字通信技术和网络信息技术,用于水上交通联络和指挥的岸—船、船一岸,以及船一船之间的通讯、导航,是在船舶之间和船岸之间自动进行航行通信、建立船舶信息交换和船舶识别的系统。它能够自动发射、接收和处理装有AIS的船舶的自身静态数据和动态航行信息,使船舶相距对遇船或岸台很远时,即能自动、连续向它船或岸基VTS(船舶交通管理中心)提供该船的实时船位、速度、航向等与船舶航行或与交通管理相关的信息,并接收它船及VTS提供的助航服务信息,从而在很大程度上有利于船舶的航行安全。 相似文献

船用甚高频(VHF)无线电通信是指采用VHF专用频段进行船舶间、船舶内部、船岸问或经岸台与陆上通信转接的船与岸上用户间的无线电通信。广泛应用于船舶避让、海事管理、港口生产调度、船舶内部管理、遇险搜救以及安全信息播发等方面,是完成水上交通现场通信的主要手段。VHF通信对于保障船舶航行安全的重要作用是其他方式的通信所无法取代的。 相似文献

互联网技术和计算机技术的迅速发展,使大数据和云计算平台逐渐成熟,并应用于多种工业控制和通信领域中。舰船交通管理系统(VTS)可以有效提高船舶航行效率,改善航运交通,但传统的VTS存在精度低、数据处理能力差等缺点。本文针对舰船交通管理系统的信息融合系统进行研究,并基于云计算技术和AIS技术开发了一种新型的VTS信息融合系统。仿真试验表明,基于云计算的VTS信息融合系统不仅雷达信号处理能力强,而且可以进行多任务并行工作,有效改善了VTS的效率。 相似文献

随着江海大桥的增多,为避免人为失误因素导致船撞大桥的事故发生,提出了以AIS、VHF-DSC、VHF-RT为基础的江海大桥主动防撞系统设计方案。该系统通过AIS发出江海大桥主桥墩的数据信息,使过往船舶的雷达上显示主桥墩的位置,明确主通航孔的位置。通过DSP数据处理单元获取船舶AIS的数据信息,分析、判断船舶的态势后由VHF-DSC选择呼叫过往船舶并发出语音提醒或警告,使船舶驾驶人员及早采取避碰措施,安全通过大桥。该系统经实地测试,验证了系统的正确性与可行性,达到了预期的设计目的。 相似文献

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region. 相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 相似文献

在船长与引航员的法律关系上,存在一些比较流行的观点和看法,却未必经得起法律思考,缺乏一定的法律依据。将《劳动法》、《合同法》、《海商法》、《船舶引航管理规定》等法律、法规和部门的规章作为依据,从法律的角度分析船长在实际工作中遇到的问题,使船长从法律的高度正确认识船长与引航员的关系,有利于船长与引航员之间关系的认识和处理,达到驾驶台团队的和谐、驾驶台资源的充分利用,进而达到增强和改善港内引航安全,做好船舶安全管理工作的目的,同时也为了避免或减少在实践中造成行政违法行为的发生。 相似文献
