iOS平台下的雪龙监控系统设计与实现

DESIGN AND IMPLEMENTATION OF XUELONG MONITORING SYSTEM BASED ON IOS PLATFORM

"雪龙"号是中国最先进的科学考察船,随着雪龙在线网络信息平台的不断发展和完善,人们对通过移动终端获取雪龙号最新信息的需求愈加迫切,为搭建一个连接雪龙号与社会公众及工作人员的i OS信息平台,设计并开发了i OS平台下的雪龙监控系统。该系统是一个C/S架构的在线App系统,实现了准实时展示雪龙号航迹、查询历史航迹、显示相关要素数据、接收和发布信息和查询关键节点信息等功能,解决了在海量航线节点中筛选关键拐点,以及航线绘制中两点连线不能通过180°经线等问题,成功地应用于辅助相关工作人员了解雪龙号最新信息,及时做出正确决策。

The R/V Xuelong is the most advanced scientific research vessel in China. With continuous development and improvement of the Xuelong＇ s online information platform, there is increasing demand for access to the latest information on the Xuelong via mobile terminals. To build an information platform to link Xuelong with the public and staff, we designed and developed a monitoring system based on the lOS platform. The system is based on the C/S structure of the online App system, and enables users to access a real-time display of Xuelong＇ s track, to query the historical track, to display relevant elements of data, to receive and publish information, and to query key node data. It solves many issues concerning route tracking, including screening of key turning points among the numerous route nodes, and the problem that straight lines cannot cross the 150 degree line of longitude. The system was successfully applied to help relevant staff access the latest information on the Xuelong and to make appropriate decisions without delay.
