Main Engine Remote Control System Realized On PLC

The main purpose of this thesis is to study NABCO M-800, one of the main type of the main engine remote control system, utilize S7-300 PLC Which is extensive used in automatization field and recognized by Ship's Classification Societies of all nations, instead of original industry computer control parts in NABCO company, to carry out all control functions of the main engine remote control system. The functions include logic controls such as normal start, restart, heavy start, normal change, emergency change, brake, stop etc; speed controls such as telegraph transmitter, accelerating rate, program load, critical speed limit, E-P changeover etc;Finish the ME remote contol system about Hardware and software design of nucleus controllers.During exploitation of the new systems, sufficiently employ the new technology of S7-300 PLC, which the new system have the module construction, university and interchange property, this make us to use ship control and manage center easily, accord with all teaching and training requirementsThe thesis has reference value in the use of S7-300 PLC, especially in the treatment of simulation measurement,...
