Container information tracing system

With the method of system engineering, a real-time pattern based on dynamic tracing was put forward, its information development period, function system, operation flow, information used for tracing and users' requirements were analyzed. The logical model of the information tracing system was established, and the elementary requirements were put forward. The method of structural system design was used to divide the information tracing system into several subsystems and function into modules, and the frameworks of database and network were discussed. An example shows that the system can guarantee the accuracy of information election, and promote the management level and network scope of container trans-portation. 1 tab, 5 figs, 8 refs.
