| In recent years, information technology is developing very rapidly and the trend of logistics informatization is becoming more and more apparent. Most logistics companies begin to use information technology to deal with the information generated in every period of logistics, including information acquisition, information transfer, information identification, information classification, information collection, information tracking and so on. Logistics tracking is the core content of logistics informatization, and is also the main direction of the research subject in this paper.Aiming at solving the current lack existing in the monitoring process of the confidential materials in road transportation, this paper proposes a logistics tracking system based on beidou satellite in order to realize the tracking in the whole process of road transportation. This logistics tracking system is based on independent intellectual property rights of China. The system is mainly divided into two parts, one is a safe transportation box embedded with beidou satellite positioning module, GPRS communication module and single-chip microcomputer controller, the other one is logistics tracking software platforai used to monitor the location and track of the safe transportation box. The basic working process of this system is as follows. Beidou satellite module gets the location information of the safe transportation box, single-chip microcomputer processes the positioning data initially and then sends it to the GPRS module; GPRS module connects with the backend server through GPRS network and Internet, then sends the positioning data to the server; server receives the data and processes it, then intuitively shows the location of the safe transportation box in GIS electronic map. The development environment of logistics tracking system is ASP.NET, using Visual Studio2008as the development tools and SQL Server2005as the database management system. And IE browser is used for the operation test of the system. |
