Key Technology Research Logistics Vehicle System Integrated Positioning Platform

With China’s economic development, the role of the logistics industry in the national economy is increasingly important. Because China has a relatively sound road infrastructure, automotive become the preferred mode of transport logistics enterprises become an essential part of the logistics industry, therefore, the effective management of logistics real-time vehicle transit logistics enterprises become an important issue to be resolved. For logistics companies, vehicle transportation endless irregularities and illegal acts, including drivers detour, Touyou fraud, high communication costs, speeding violations, these factors will lead to increased transportation cost of logistics enterprises, reducing the transport efficiency, to a certain extent restricted the development of the logistics industry. After positioning technology from military to civilian, logistics enterprises provides an effective means to strengthen the vehicle management. By positioning technology based on integrated management platform for logistics vehicles, logistics companies can achieve real-time vehicle tracking and monitoring, improving logistics vehicle scheduling efficiency, reduce the possibility of man-made accidents, violations occurred.The topics to location-based technology platform for integrated management of logistics vehicles for the study, based on the key technology research and in-depth needs analysis, carried out the design and implementation of the system. Topic briefly describes the history and current status of the development of logistics vehicles integrated management system, and then conduct in-depth research on key technologies of mobile positioning technology, GPS positioning technology, GPSONE positioning technology, geographic information systems and other systems involved, based on the analysis of the logistics needs the overall framework of integrated vehicle positioning system was designed for vehicle mobile terminal system, central monitoring end, WEB maintenance management module for more detailed design. Considering the economy and reliability, the system uses GPS and GPSONE hybrid positioning technology, communication module uses a network communication(CDMA, GPRS) and SMS communications mutual backup mode, with high flexibility and reliability. System map server selected MapXtreme for Java, using Java Applet development of user interface to achieve a vehicle positioning operation and electronic map display, GPRS communication vehicle side and the center side to solve the positioning of logistics vehicles, through logistics vehicle positioning module and Web Gis The combined system also provides vehicle position based on the electronic map display and scheduling functions. Finally, the test side and process systems.
