【摘要】：与常规物流相比,应急物流通常表现出突发性、不确定性、弱经济性、时间的紧迫性等特点,而且在应急物流中,常规通信和交通基础设施的使用会或多或少的受到限制,针对这些特点,本文综合利用嵌入式技术、嵌入式GIS技术、北斗卫星导航通信技术、数据库技术等设计并开发出一个面向应急物流的嵌入式移动终端。面向应急物流的嵌入式移动终端系统选用韩国三星公司推出的基于ARM1176JZF-S内核的S3C6410芯片为微处理器、嵌入式Linux为操作系统、Qt为图形用户接口,在此基础上进行应用程序的开发,实现定位导航、应急通信、在运物资管理等功能。本文的主要工作有：(1)关键算法的理论研究。通过在静态交通网络模型中加入抢修时间这一系数,建立了动态交通网络模型,提出了针对应急物流的最优路径选择算法——改进的Dijkstra算法。(2)系统软硬件平台的设计。设计基于S3C6410嵌入式微处理器芯片的系统硬件电路,针对ARM目标板定制与移植BootLoader、Linux内核、根文件系统及Qt GUI。(3)系统应用程序的设计。对基于MIF格式电子地图的嵌入式GIS、基于北斗卫星的长报文通信和基于SQLite数据库的在运物资管理等关键功能模块的实现过程给予了详细的介绍。
[Abstract]:Compared with conventional logistics, emergency logistics usually shows the characteristics of sudden, uncertainty, weak economy, urgency of time, and in emergency logistics, the use of conventional communication and transportation infrastructure will be more or less restricted. Aiming at these characteristics, this paper designs and develops an embedded mobile terminal for emergency logistics by using embedded technology, embedded GIS technology, Beidou satellite navigation communication technology, database technology and so on. The embedded mobile terminal system for emergency logistics uses S3C6410 chip based on ARM1176JZF-S kernel developed by Samsung Company of South Korea as microprocessor, embedded Linux as operating system and QT as graphical user interface. On this basis, the application program is developed. Achieve positioning and navigation, emergency communications, in the transport of materials management and other functions. The main work of this paper is the theoretical study of the key algorithms. By adding the coefficient of rush repair time to the static traffic network model, the dynamic traffic network model is established, and the design of the software and hardware platform of the system is presented, which is the best route selection algorithm for emergency logistics, the improved Dijkstra algorithm. The system hardware circuit based on S3C6410 embedded microprocessor chip is designed. The design of system application program for arm target board customization and transplanting Boot Loadern Linux kernel, root file system and QT GUI 3) is presented. The realization process of the key function modules such as embedded GIS-based MIF format electronic map, long-message communication based on Beidou satellite and the management of goods and materials in transit based on SQLite database are introduced in detail.
