【摘要】 张家港做为一个港口工业城市,日均货物吞吐量达到了相当大的规模。港口危险化工品的物流运输调研数据显示,化工品运输中偷盗油料和化工品的行为时有发生,企业为此付出了每车每年数万元的代价,张家港迫切需要杜绝油罐车司机偷盗油料的行为。本论文的研究是基于危化品运输管理现状和存在的问题以及张家港市政府对提高危化品运输管理水平的积极态度应用。本论文的研究意义在于全过程安全监测危化品运输,提高危化品运输管理水平。危险化学品运输信息管理系统,能够实时接收运输载体传送给监控中心的危化品状态和车辆的位置等其他信息,然后将其存储在数据库中,管理员和用户能够通过互联网查询危机化学品的信息,监控中心也可以发送命令到运输车辆。结合张家港物流园区的工程需求,设计了一套基于GPS/GIS的危化品信息管理系统。数据服务中心(Data Server Center)简称DSC,,不仅是危化品信息管理系统中服务器软件的核心功能单元,也是整个服务器的数据逻辑处理中心。车载终端与服务器通信,与用户界面交互以及服务器与数据库交互等任务都由DSC承载。本文将系统的分析DSC的数据实现,与用户界面交互,与数据库交互,与车载终端的通信以及其内部数据同步管理等问题;另外将系统解析如何提高服务器性能,实现关系数据库和XML数据的性能互补.更多还原

【Abstract】 Zhangjiagang as an industrial port city, daily cargo throughput have reached a considerable scale. Port logistics research data shows that there are many theft in oil and other chemical’s transit.Companies have to pay millions a year, Zhangjiagang need to prevent the theft of fuel tanker drivers urgently.This paper’s research is based on the existing problems of hazardous chemicals transporting management situation and Zhangjiagang government’s positive attitude towards improving the hazardous chemicals transporting management level.The significance of this paper is to achieve the whole safety monitoring during hazardous goods transporting, and improve the transporting management level.The dangerous chemicals transporting management information system can receive real-time transporting information and transmitted it to monitoring center, such as hazardous chemicals status, vehicle location and other information, then stored it in a database, administrators and users can query hazardous chemicals information via the Internet, and monitoring center can also send commands to the transport vehicle.Combined the engineering requirements of Zhangjiagang logistics park,this paper designed a hazardous chemicals information management system based on GPS / GIS. Data Server Center refers to DSC, is not only the core functions unit of hazardous chemicals information management system server software, but also the data logic processing center for the entire server. Vehicle terminal communicates with the server, DSC hosts the interacting with the user interface and interacting with the database server. This paper will analyze DSC data system implementation,communications with user interface, database, vehicle terminal and its internal data synchronization management issues;and analyze how to improve server performance, achieve the performance complementation between relational databases and XML data.更多还原
