At the engine room of medium speed and low speed engines, various assistive devices are installed to accomplish operation by mutual relationship. For the operation of engine and assistive devices, the condition of engine and engine room must be monitored and recorded at all times for the safety of system and optimum operation status. Also, as the optimum operating condition gets to have important effect on the life span of engine because the engine is installed at the site, a steady monitoring and control must be accomplished for the performance or durability of engine and to be operated under normal conditions. In this study, a wire/wireless communication system transmitting the operation data of engine from the ER(Engine Room) to the engine controller of ECR(Engine Control Room) has been developed through the communication of ISM(Industrial Science Medical) band for the test operation environment improvement of medium speed engine. This wire/wireless communication system is composed of the RTU(Remote Terminal Unit) gathering and transmitting engine data as well as the MCU(Master Control Unit) receiving engine status information from the RTU to be sent to the engine controller(PLC). Through this study, a trial product of RTU and MCU has been manufactured. A test bench that has made temperature, pressure and pick-up sensor into a module for the local test of trial product will be designed to manufacture a test bench in the future. And the field test will be performed under the test operation environment of medium speed engine by going through a local test.
