Design And Implementation Of GIS Terminal For Vehicle In Tobacco Distribution Based On Android

Integrated mobile Internet,sensor networks and RFID technology into traditional tobacco logistics,the tobacco logistics will gradually implement informatization and intelligent managing in distribution links.Based on the research on the lack of supervision in tobacco logistics distribution,the design requirements of the project and related technology of Geographic Information System,it has given the design and implementation of Android-based GIS vehicle terminal for tobacco distribution in this paper.It can implement informatization management,and realize the aim of real-time management and monitoring at tobacco distribution links,through the result of hardware and software joint test.On the basis of analyzing requirements of GIS development,the design of Android based GIS terminal mainly includes database design,route planning algorithm and business function design.In the design of database,it mainly researches and compares the advantages and disadvantages of the database three-tier architecture in this paper.According to the project needs,it designs the database three-tier structure of the terminal.In the realization of route planning algorithm,based on the characteristics of genetic algorithm and greedy algorithm,two schemes are designed and implemented under different scenarios in this paper.In the design of business function,based on the work needs analysis,it has designed and implemented order querying,route planning and navigating,auxiliary signing,track tracking and other functions for the GIS terminal.The main work of this paper is as follows:Firstly,it analyzes the advantages and disadvantages of different tools in GIS development,selects Baidu Map API and related technology of GIS from economic and technical level.And it makes an in-depth study on the structure and operation mechanism.Secondly,based on the three-tier database structure,terminal database structure has been designed and developed according to the actual needs of the project in this paper.And in the view of the practical requirements,it realizes the database operation method in this paper.Thirdly,according to the terminal function design requirements,it has been designed that the overall scheme of geographic information collection and tracking functions for the GIS terminal.And the terminal has realized the route planning algorithm,and implemented map positioning tracking,route planning and navigation functions.Combined with mobile Internet technology,it realizes the data upload and download functions.And the bar code scanning function is designed in this paper.
