Abstract
The ESS(Energy Saving System) is designed to have functions of controlling. monitoring for cooling system. etc. ESS consists of the I/O module, CPU module and Display module I/O module detects various ESS data on local area and treats signals via I/O interface system. The interface system receives various status data and outputs control signals. ESS is tested with dummy signal to verify proposed functions and is shown good results. For future study ESS will be tested under real condition in the ship.
