Energy-flow-based ship power plant state monitoring system and method

Abstract

The invention provides an energy-flow-based ship power plant state monitoring system. The energy-flow-based ship power plant state monitoring system comprises a sensor set, a converter, an energy flow display device and a fault alarm device which are connected in sequence; the sensor set is used for collecting related parameter data of a corresponding power consumption device; the converter is used for processing data collected by the sensor and converting the collected data into a data form of energy; the energy flow display device is used for letting people know the operation state of the ship power plant through displaying energy flow directions and numerical values of energy consumption devices in real time; and the fault alarm device is used for alarming when a safety failure or abnormal energy flows happen. The invention also provides an energy-flow-based ship power plant state monitoring method. The energy-flow-based ship power plant state monitoring system and method introduce an energy flow principle, can determine and eliminate equipment faults through monitoring and controlling energy flows, add the energy consumption alarm device on the basis of the original fault alarm device, and guarantee the ship power plant to always operate safely and efficiently.

Description

technical field [0001] The invention relates to a ship power monitoring system and method, in particular to a ship power device state monitoring system and method based on energy flow, and belongs to the technical field of ship performance monitoring systems. Background technique [0002] Ships play an important role in waterway transportation, ocean development and defense of sea rights. Fast, efficient and energy-saving has become the goal of development. At present, the effective energy utilization percentage of the three main ship types is about 32%, which has a large space for energy saving, and the sum of losses in the main propulsion system accounts for more than 50% of the total input energy, and the lost energy is not clearly defined. The specific reasons for the loss cannot be carried out in a targeted manner. [0003] The marine equipment in the prior art mainly monitors the real-time status of the main energy-consuming equipment of the ship through performance ...

AI Technical Summary

Problems solved by technology

Using the existing mode, only 30%-40% of the faults can be detected for a single method of monitoring. Although the comprehensive monitoring of multiple methods can improve the monitoring performance, it can better monitor the status of the equipment and carry out related fault diagnosis, but it will cause information Redundancy increases monitoring costs

In addition, the existing monitoring mode basically only stays at the level of safe operation of equipment, seldom involves energy consumption monitoring, and cannot provide reference suggestions for solving the problem of high energy consumption of ship equipment
