摘要
"数字航道"建设的主要目标在于应用信息技术平台保障航道安全、提高航务管理水平。作为航道管理中的重要导航设施航标灯(船),对其工作状态、空间位置进行远距离全天候监测与遥控是"数字航道"建设的主要内容。航标遥测监控系统集成无线通讯、传感器、空间信息处理等技术,实现航标信息的实时采集与传输,异常状况的报警及统计等功能。电子航道图运用事件驱动型地图表达、时空变化特征地图表达、多尺度地图表达及国际电子海图S57/S52标准表达等关键技术,为监控航标提供地理定位背景,并支持遥控监测中的空间信息查询、分析等功能。
It is useful for sailing to monitor and control remotely the navigational marks which are located at both sides of the inland waterway.The monitoring system integrates the technologies of wireless communication,geo-sensor network,GPS,spatial information handling and others to collect and convey the real-time information about buoys,and to give alarms for abnormal situation of navigational marks.The electronic waterway map is the geographical foundation for representation of navigational marks＇ situation.It supports the retrieval,analysis,and representation of spatial information.The paper discusses the technologies of the dynamic electronic map used in the system,which includes map representation driven by event,map representation for the changing temporal-spatial features,visualization of multi-scale waterway data,extension of S57/S52 standard for inland waterway application,real-time monitoring and alarm for navigational marks.
