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 ...

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0026] Such as figure 1 The shown energy flow-based ship power plant status monitoring system is composed of a sensor group 1, a converter 2, an energy flow display device 3 and a fault alarm device 4, and is installed in the ship power plant. When the ship's power plant starts to run, the sensor group will collect relevant parameters and transmit them to the converter 2 in real time. Displayed on the energy flow display device 3; and when the ship's power plant fails, a corresponding alarm prompt will appear on the alarm device 4 until the fault is eliminated and the normal monitoring state is restored. Its monitoring diagram is as follows fi...
