Embodiment 1

[0081] Such as figure 1 As shown, the present embodiment provides a low-speed diesel engine economic analysis method, comprising the following steps:

[0082] Step S1 offline training, select the historical health sample data as the input data of offline training, construct the low-speed diesel engine economy evaluation baseline and the health baseline of economically related components;

[0083] Step S2 online analysis, analyzing the economic status according to the online monitoring data, when the economic status is normal, end; when the economic status is abnormal, perform health status analysis;

[0084] Economic status analysis, based on the low-speed diesel engine economy evaluation baseline, the fuel economy analysis is carried out to obtain the fuel economy status results of the low-speed diesel engine;

[0085] Health status analysis, based on the health baseline of economical related components, the health status analysis of low-speed diesel engine economical relate...

Embodiment 2

[0167] Using the above method to monitor a main engine (the brand is MAN, the model is 5S60ME) used in a 10,000-ton bulk carrier, the monitoring data related to the economy of the diesel engine includes operating status, fuel consumption (direct economic parameters) , Main engine cylinder system (including cylinder exhaust temperature, cylinder piston cooling oil outlet temperature, cylinder liner cooling water outlet temperature, cylinder scavenging tank misfire temperature), supercharger system (supercharger speed), air cooler system ( Typical parameters such as the temperature difference between the front and rear sweep air of the air cooler).

[0168] Part 1: Offline Training Results

[0169] According to the offline training steps of the above-mentioned embodiment 1, input the economical data related to the trouble-free and smooth operation of the ship from 2016 / 8 / 15 to 2016 / 9 / 15, including speed, fuel efficiency, No.1-5 cylinder exhaust temperature , No.1-5 cylinder pis...

Embodiment 3

[0177] This embodiment provides a host economic analysis system, including an offline training module and an online analysis module;

[0178] A data selection module, which is configured to select stable working condition data in historical health samples as input data for offline training;

[0179] a baseline building block configured to execute the build host economics assessment baseline and economics-associated component health baseline;

[0180] An online data acquisition module configured to perform online acquisition of economically relevant monitoring data;

[0181] an economic status analysis module configured to perform an economic status analysis of the host using the constructed host economic assessment baseline;

[0182] Judgment and selection module, which is configured to execute when it is judged that the economical state is normal, the selection ends; when it is judged that the economical state is abnormal, analyze the health status of the associated componen...

Abstract

The invention relates to a decline contribution degree-based marine main engine associated component state monitoring method and system. The method selects stable working condition data in historicalhealth samples as input data for offline training, and a main engine economy evaluation baseline and an associated component economy health baseline are built; economy related monitoring data are acquired, the built main engine economy evaluation baseline is used to online analyze the main engine economy state, and when the economy state is normal, the operation is ended; when the economy state isabnormal, an abnormal alarm is given, and main engine associated component health state analysis is carried out; and the health state result of each component and the maintenance and investigation order for the components are obtained. The method and the system carry out main engine economy state judgment and main engine associated component health state monitoring at the same time, maintenance of the main engine and the associated components is effectively guided, the economy performance of the main engine is recovered, hidden dangers or exception / fault of the associated components are eliminated, the fuel cost is reduced, and practical significance is extremely facilitated.

Description

technical field [0001] The invention relates to the field of evaluation and analysis of the economic performance of a ship main engine, in particular to a method and system for monitoring the status of related components of a ship main engine based on the contribution degree of decline. Background technique [0002] As a means of transportation with a large volume of transportation, ships account for 40-60% of their operating costs to fuel consumption. Among them, the ship's main engine is the "heart" of the ship's power, and its fuel consumption usually accounts for 90% of the entire ship's fuel consumption. Above; taking an ocean-going 10,000-ton ship as an example, the fuel consumption of its main engine per voyage is more than 20-30 tons, which greatly affects the ship operating costs of shipping companies, especially in the current market environment where the shipping market continues to slump , how to reduce costs and increase efficiency has become the focus of attent...
