Abstract: With the higher requirement of all the industry for the function of the automated storage and retrieval system，and some special requirement for storage of some goods, a special type of automated storage and retrieval system was designed and realized. Linear motion units was used as motion carrier to constitute the whole mechanical structure of the system, CAN bus was used as the field bus to constitute the local area network,the high safety distributed and realtime control was realized. And at last, finite state machine(FSM) was used to model and design the system controller. As a result, a sort of special automated storage and retrieval system with low cost and high performance is invented and put into application.
Key words: automated storage and retrieval system; CAN bus; finite state machine (FSM)
