Abstract


The main content of the subject is a programmable logic controller (PLC) of the production by Zibo Diesel Engine Factory 6300ZLCA type not change to the medium-speed diesel engine , reduction gear box , and fixed -pitch propeller propulsion system designed by AUT-0 standards a The remote control system . The system uses Siemens S7-300 series programmable logic controller , the combination of programming (LAD) for language and Structured Control Language (SCL) to achieve the basic propulsion system control functions , including : operating parts switching function , logic control functions , speed and load control and limit the functionality , security and emergency operation function and the communication function of the bell . System in the development process , and make full use of the advantages and characteristics of S7-300PLC , the system has a distributed architecture . The system uses two sets of PLC station design set for telegraph communication bridge between the centralized control room and machine beside ; another set for the status of the host , the gearbox data acquisition and logic control . Between two PLC stations communicate via PROFIBUS network , when the failure of a PLC station does not affect another set of normal work , independent of each other in order to achieve control and telegraph communication . In addition, the stage in the bridge with the central control room of remote manipulation using micro-computer data exchange with the remote control system of the interaction between the computer and the PLC via PROFINET network . This article is generally divided into five parts : the first part of the overall structure of the remote control system design ; second part is the in-depth study of the remote control system to achieve the function ; The third part is for the remote control system to achieve the functionality hardware design ; fourth part is the software part of the remote control system design ; final design of the communication network of the remote control system , to achieve PROFIBUS and PROFINET communications network to establish as well as point-to-point communication function .
