A kind of crane loading and unloading simulation based on finite-state Machine

Abstract

Aiming at the insufficiency of the actual crane, finite state machine technology was adopted for setting up an emulational training system. The system implemented a kind of crane loading and unloading operation. Therefor a sort of finite-state machine for the crane was set up. By the dynamics analysis for the crane, several states of the finite state machine were established during loading and unloading process. All the states were bewritten with some mathematic models. The models were simplified to adapt to the simulation system. Then the flow for establishing finite state machine was given, and the concrete methods in Unity3D engine for establishing finite state machine were described. Finally an instance of a kind of crane loading and unloading training system was implemented based on the aforementioned models and methods. The instance shows that the models are accurate and the finite-state machine states are logical.

“…To meet IoC, we set Interaction behavior as Finite state machine (FSM).FSM is a mathematic model describing finite state, transition behavior between all the states and all the actions of the states. FSM can be shown by a directional figure, it can be defined as [5]:…”
