New Control Device for Governor Handle of Main Engine Remote Control System

Abstract

Almost all of ocean going vessels, today, are intended to be operated with an unattended machinery space, therefore, high reliability and easy maintenance of automation equipments are required especially for main engine remote control divice. A new control device for governor handle of main engine remote control system developed by MHI Kobe shipyard has unique transmitters and function generator to convert the out-put signal from linear order signals to non-linear control signals. The above mentioned transmitter is of special transformer type called "LINIAX" without any contact parts, and lead wires for translation from mechanical movements to electric signals. The function generator is composed of an IC operational amplifier and has trimming potentiometers for adjusting of knuckle points and gains of the out-put signal, because the order transmitter is combined with a telegraph handle. A pneumatic actuator of MHI make is used for governor handle of engine side. We believe that MHI's new engine remote control device will show high reliability and easy maintenance.
