Taking the trucks and cargoboats monitoring system development for the logistics management department of an iron and steel enterprise as the background, the achievements in transportation bills tracking and systems integration are deeply summarized. The management and control automation requirements of the iron and steel sales logistics are analyzed. The system logical structure which consists of the data layer, the application layer and the representation layer is proposed. After that, the system architecture which consists of the communication server, the application server and the database server is also proposed. Finally, the key implementation technologies and the functions of clients are given. The functions of the C/S client include the status monitoring of trucks and cargoboats, history track replay, transportation bills tracking, abnormal transportation warning, and realtime analysis of transportation ability. The B/S clients are integrated with the CRM of this enterprise, where the remote customers can query the realtime position and the speed information of the corresponding trucks or cargoboats by the order number.
