基于WEBGIS的物流监控实验平台设计与实现
|
摘要
物流监控系统是现代物流信息化建设的重要方面,通过车载数据终端、无线通信网络和物流监控平台,为物流企业管理信息化提供强有力的技术支持。物流监控平台是整个物流监控系统的管理中枢,利用地理信息系统GIS的空间分析和决策技术对物流车辆进行实时监控和科学调度。
网络地理信息系统WebGIS综合Web技术和GIS技术,利用网络技术扩展和完善地理信息系统,实现网络环境下的空间信息管理,具有互操作性,可移植性、扩展性和跨平台性等特点。相对于传统上基于GIS的物流监控平台,基于WebGIS的物流监控平台信息共享更方便,负载计算更平衡,数据访问更高效,成本开销更节约。
课题设计并实现了一套基于WebGIS的物流监控实验平台。平台由监控终端、Web应用服务器、GIS应用服务器和数据库服务器组成,地理信息数据和车辆信息数据存储在数据库服务器中,由Web应用服务器和GIS应用服务器协同工作处理,最终在监控终端的电子地图上可视化显示,实现对物流车辆的监控、查询和调度。
论文在对WebGIS进行综述的基础上,重点研究出基于WebGIS的物流监控实验平台的设计方案,并针对实际应用,提出结合J2EE标准构建分布式监控平台,引入数据库连接池机制提高数据访问效率,使用JSP+JavaBeans技术扩展平台功能等三项性能优化策略,并详细分析了平台关键功能的实现过程。
物流监控实验平台经过配置调试,运行稳定,能够满足较大规模的物流监控需求,具备实际应用的价值。
The logistics monitoring system, which provides cogent technical support for logistics enterprise via the vehicle data terminal, wireless communication network and logistics monitoring platform, is important part of modern logistics informationization construction. As system management centrum, the logistics monitoring platform implements real time monitoring and correctly assigning to logistics vehicle by geography analysing and decision-making technique of GIS.
WebGIS, combo of Web and GIS, make use of Web technique extending and reinforcing GIS, so as to realize geographical information management in Web environment. Moreover, WebGIS possesses the characters of mutual operation, portability, expansibility and compatibility. Compared with traditional logistics monitoring platform based on GIS, the platform based on WebGIS is better in information shareing, load computing, data accessing and cost spending.
This project designs and implements a set of logistics monitoring simulation platform based on WebGIS. The platform is composed of monitoring terminal, Web application server, GIS application server and database server. Geographic information data and vehicle information data, stored in Database server, are co-processed by Web application server and GIS application server, and finally are visually displayed in the map of monitoring terminal where users could execute operations such as monitoring, searching and assigning towards logistics vehicles.
This thesis firstly summarizes WebGIS, and then put emphases on designing scheme of logistics monitoring simulation platform based on WebGIS, in which three optimized policies are put forword for practice, including constructs distributed monitoring platform combining with J2EE standard, improves data accessing efficiency importing database connectpool mechanism and extends platform function adopting JSP+JavaBeans technique.
After configuring and debugging, the logistics monitoring simulation platform is proved to be running stably, this could satisfy with requirement of bigger scale logistic monitoring, and is valueable in business application.
