Research On The Vehicles Management And Control System For Sales Logistics Of A Giant Iron And Steel Enterprise

The logistics of giant iron and steel enterprise which involves the product information collection, scheduling and monitoring of vehicles and other areas,has many characteristics, such as the large transportation amount, the long logistics path and the complicated transportation mode. The establishment of an advanced logistics management and control system is made possible by the rapid development of modern GPS/GIS spatial information, mobile communication and the computer network technology. The application of such systems can reduce the logistics risk and improve its efficiency. For the special demands of iron and steel enterprise, the research for the development process of GPS management and control system, the discussion for the information system design and implementation of the control operations, such as intelligent alarm, vehicle monitoring and product track, has important significance.From the overall design perspective, the logic architecture, C/S system structure and database construction based on GPS/GIS technology is elaborated by this thesis, a detailed analysis of communication protocols is conducted and the equipment selection is finished. Base on the three-tier C/S model design, the GPRS server, application client server, client and other software modules is detailed designed by this thesis and a lot of management and monitoring functions such as location, region scheduling, product track, intelligent alarm, electronic map display and query, transport capacity analysis is realized. What's more, an integration method based on XML and multi-thread network communication technology is carried out, successfully applied to WISCO GPS management and monitoring system, which ensures data can be transferred completely, instantly and correctly.The functions of the existing domestic GPS monitoring system is expanded by the GPS control system project.?The special requirements of large-scale iron and steel sales logistics is met better, so it's worth to be implemented in iron and steel enterprise logistics.
