Design and Implementation of Marine Engine Room Monitoring and Alarm System

This paper designs and realizes a marine engine room monitoring and alarm system based on the controller of Siemens PLC, introduces the design means and the practice process in detail, optimizes the system structure then uses the Profinet, carried out the monitor alarm system's each function with the monitoring and communication program which uses the PLC's trapezoidal chart language And with the Visual Studio 2022 as the developing platform, carried out the program in the position machine with the C# programming language. The system has been used in the experimental teaching, scientific research and real ship, and the results show that the system has the merits of better stability, stronger extension, better effect and so on.
