Drugstore Control System Design and Realization Based on Programmable Logic Controller (PLC)

Abstract

This paper proposes an intelligent storage and automatic drug delivery system based on PLC. This system can be applied to dispensing work for all type of medicines. Firstly, the essentials of intelligent control system are discussed and then overall scheme of the system design is presented. Secondly, introduction to the software and hardware design of control system, including the selection of PLC and motion control system are described. Lastly, by analysis of E-R diagram, the date is established and communication protocol between systems is customized. This paper also gives the implementations of the multi-threaded system and communication method.
