【摘要】：與常規(guī)物流相比,應(yīng)急物流通常表現(xiàn)出突發(fā)性、不確定性、弱經(jīng)濟(jì)性、時(shí)間的緊迫性等特點(diǎn),而且在應(yīng)急物流中,常規(guī)通信和交通基礎(chǔ)設(shè)施的使用會(huì)或多或少的受到限制,針對(duì)這些特點(diǎn),本文綜合利用嵌入式技術(shù)、嵌入式GIS技術(shù)、北斗衛(wèi)星導(dǎo)航通信技術(shù)、數(shù)據(jù)庫(kù)技術(shù)等設(shè)計(jì)并開(kāi)發(fā)出一個(gè)面向應(yīng)急物流的嵌入式移動(dòng)終端。 面向應(yīng)急物流的嵌入式移動(dòng)終端系統(tǒng)選用韓國(guó)三星公司推出的基于ARM1176JZF-S內(nèi)核的S3C6410芯片為微處理器、嵌入式Linux為操作系統(tǒng)、Qt為圖形用戶接口,在此基礎(chǔ)上進(jìn)行應(yīng)用程序的開(kāi)發(fā),實(shí)現(xiàn)定位導(dǎo)航、應(yīng)急通信、在運(yùn)物資管理等功能。 本文的主要工作有：(1)關(guān)鍵算法的理論研究。通過(guò)在靜態(tài)交通網(wǎng)絡(luò)模型中加入搶修時(shí)間這一系數(shù),建立了動(dòng)態(tài)交通網(wǎng)絡(luò)模型,提出了針對(duì)應(yīng)急物流的最優(yōu)路徑選擇算法——改進(jìn)的Dijkstra算法。(2)系統(tǒng)軟硬件平臺(tái)的設(shè)計(jì)。設(shè)計(jì)基于S3C6410嵌入式微處理器芯片的系統(tǒng)硬件電路,針對(duì)ARM目標(biāo)板定制與移植BootLoader、Linux內(nèi)核、根文件系統(tǒng)及Qt GUI。(3)系統(tǒng)應(yīng)用程序的設(shè)計(jì)。對(duì)基于MIF格式電子地圖的嵌入式GIS、基于北斗衛(wèi)星的長(zhǎng)報(bào)文通信和基于SQLite數(shù)據(jù)庫(kù)的在運(yùn)物資管理等關(guān)鍵功能模塊的實(shí)現(xiàn)過(guò)程給予了詳細(xì)的介紹。
[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.
