An extensible multi channel servo control device for marine application

A variety of operational control methods integrated in electromechanical servo control devices are in huge demands, such as modern ships which have a high equipment vibration noise and reliability demanding and need long distance operation occasion. The electric control cabinet was designed in this paper, which integrated many operating modes such as remote-control operation, local-control operation and manual operation to control the motor-screw device precisely. It can switch operating modes at any time according to the requirements of on-site console. High reliability is also designed in this device, when one control mode fails, the other control modes can be used to control the motor. What's more, equipment vibration and noise are well considered and reduced by improving control methods. The equipment also adds relevant safety design.
