Digital Circuit Simulation of a Discrete System

In order to seek a new simulation modeling method of container terminal systems and to overcome some shortcomings of the existing methods, a digital logical circuit simulation model of unloading operation was build for simulating the working condition of container handling equipments and logic events by software Electronics Workbench5.0. Simulation results show that the model can accurately reflect actual unloading operation and that it´s feasible to simulate discrete systems by digital circuit simulation software. Then, an implementation method for container terminal systems´ simulation using Hardware Design Language (HDL) was proposed. This study contributes to reducing differences among system simulation experiments, reality system and automatic control design of terminal systems, and Hardware/Software Co-design of terminal systems.
