Intelligent ship engine room monitoring alarm system based on model

Abstract

The invention discloses an intelligent ship engine room monitoring alarm system based on a model. The system comprises a control system, a power system and a load system. A main propulsion system of aship shows a work state of the control system according to a change rule of parameters of a rotation speed fluctuation ratio, a rotation direction and a rotation speed. A thermal work process parameter of a host is used to represent a work state of the power system. A memory, one or more processors, and one or more programs are included. One or more programs are stored in the memory and are configured to be a process that one or more processors execute so as to complete fault type determination and an engine room system is integrally assessed. In the invention, through combining analysis of aconventional thermal parameter, mechanical states of motion parts are inspected and monitored according to a vibration signal so as to avoid a major sudden accident and realize integration assessmentof an engine room environment, marine engineer quality and a ship management level.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a model-based intelligent ship engine room monitoring and alarm system. Background technique [0002] During the normal navigation of the ship, the working status and parameters of the main engine, generator set and other equipment in the engine room are constantly changing. In order to keep abreast of the operation of the equipment, a real-time and reliable engine room monitoring and alarm system is required. . When the operating parameters of the equipment exceed a certain preset limit value, an audible and visual alarm can be issued to remind the on-duty engineer, which can improve the fault prevention ability and shorten the time for troubleshooting and handling faults. The existing ship engine room monitoring and alarm system monitors the working conditions of various equipment in the entire engine room by collecting signals such as the temperature, pressure, speed, f...
