Embodiment 1

[0089] Such as figure 1 As shown, the present embodiment provides a low-speed diesel engine economic analysis method, comprising the following steps:

[0090] 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;

[0091] 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;

[0092] 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;

[0093] 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

[0173] The above method is used to monitor a low-speed diesel 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 ), low-speed diesel engine cylinder system (including cylinder exhaust temperature, cylinder piston cooling oil outlet temperature, cylinder liner cooling water outlet temperature, cylinder scavenging air box misfire temperature), supercharger system (supercharger speed), air cooler Typical parameters such as system (scavenging temperature difference before and after the air cooler).

[0174] Part 1: Offline Training Results

[0175] According to the off-line training steps of the above-mentioned embodiment, 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 cy...

Embodiment 3

[0182] This embodiment provides a low-speed diesel engine economical analysis system, including an offline training module and an online analysis module;

[0183] Carry out economic status analysis and health status analysis based on online monitoring data;

[0184] The offline training module includes a data selection module and a model building module;

[0185] Data selection module, used to select historical health sample data as input data for offline training;

[0186] Model building blocks for constructing low-speed diesel engine economy assessment baselines and economy-related component health baselines;

[0187] Online analysis modules, including economic analysis module and health status analysis module;

[0188] The economic status analysis module performs fuel economy analysis based on the low-speed diesel engine economy evaluation baseline to obtain the fuel economy status results of the low-speed diesel engine;

[0189] The selection module is used to choose to...

Abstract

The invention relates to a double baseline-based low-speed diesel engine economy analysis method and system. Historical health sample data are selected as input data for offline training, and a low-speed diesel engine economy evaluation baseline and an economy associated component health baseline are built; economy state analysis is carried out according to monitoring data, when the economy stateis normal, the operation is ended; and when the economy state is abnormal, health state analysis is carried out. The method and the system carry out economy evaluation and influence factor analysis from a direct angle and an indirect angle, maintenance of the low-speed diesel engine can be effectively guided, the economy performance of the low-speed diesel engine is recovered, hidden dangers or exception/fault are eliminated, the fuel cost is reduced, and practical significance is extremely facilitated.

Description

technical field [0001] The invention relates to the field of evaluating and analyzing the economic performance of diesel engines, in particular to a method and system for analyzing the economics of low-speed diesel engines based on double baselines. Background technique [0002] As a means of transport with a large volume of transportation, ships account for 40-60% of their operating costs to fuel consumption, among which low-speed diesel engines are the power "heart" of ships, and their 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, its low-speed diesel engine consumes more than 20-30 tons of fuel per day of voyage, which greatly affects the ship operating costs of shipping companies, especially in the current market environment where the shipping market continues to slump Among them, how to reduce costs and increase efficiency has become the focus of the users of shipping companies...
