基于PLC柴油主机推进控制系统的研制

his paper introduces the feature and function of the propulsion control system for the marine main diesel engine with gear box, the center of which is the programmable logical controller. The system has the characters of manipulation of simple ,high reliability, easy expansion of functions and easy maintenance. The research result indicates that use the technology of PLC in the main engine propulsion control system is of distinct superiority in many respects, that a winder application is in prospect.
