Design Of Logistics Experimental System Based On PLC Network

This article introduced the development and the design of modernlogistics experimental system based on PLC control network, and thedesign of computer monitoring system.First,, combining with laboratory background, we regard PLC as thecore control unit of logistics system through in-depth research to thecontrol network. This system uses industrial Ethernet to realize theintelligent control of logistics system.The accuracy and fast access of datarealize the intelligent and automation of the system,and fundamentallyensure the stability and quickness of data transmission.The system usesSQL Server data management system, providing stable and strong datastorage efficiency.And it can realize the data remote visit anduse,improving the system extensibility of system.The system take stored in a storehouse the thing to flow the system asthe object, and uses the photo electricity localization, the frequency conversion velocity modulation, the computer vision cargo automaticdiagnosis, the intelligent optimization dispatch, the networkcommunication technology and the robot automatic scan and the depositand withdrawal and so on the advanced technology, which involve theautomation technology, the computer technology, the networkcommunication, the robot technology, the actuation and the monitortechnology, visual and the bar coder ecognition technology, theintelligent optimization dispatch and soon many advanced areas oftechnology. The PLC control network uses SIEMENS S7-200and theS7-300series programmable controller, introduced PLC through theethernet interface module hardware connection, as well as on positionmachine monitoring software design.It realizes the ethernet skeleton of logistics system and thelong-distance monitoring function thing successfuly through the useexisting local area network,which manifested the industrial automation technology distributional, openly and information of the industrialautomation technology.
