Embodiment Construction
[0081] Hereinafter, the main engine monitoring method, the main engine monitoring system, the main engine state prediction system, and the navigation state prediction system of the ship realized by the embodiments of the present invention will be described.
[0082] figure 1 It is a block diagram of the main engine monitoring system of the ship realized in this embodiment.
[0083] The host monitoring system of the ship has: the host 10 of the ship; the operation setting mechanism 20, which sets the set value related to the operation of the host 10; the measuring mechanism 30, which obtains the main measured value of the host 10; the host virtual model 40, which sets The physical model representing the response of each constituent element of the host 10 is obtained by combining the physical models; the calculation mechanism 50 applies the set value and the measured value as the host state parameters to the variables in the model of the host virtual model 40, and performs the c...

The present invention addresses the problem of providing: a ship main engine monitoring method capable of monitoring a main engine state with an accuracy comparable to actual measurements, without requiring much actual measurement equipment; a main engine monitoring system; a main engine state prediction system; and an operation status prediction system. In the present invention, a primary measurement value and a setting value pertaining to the operation of a main engine (10) of a ship (A), the setting value being a main engine state parameter serving as an intra-model variable, are applied to a main engine virtual model (40) based on a combination of physical models representing a response for each constituent element of the main engine (10). Calculations are performed with the main engine virtual model (40) to monitor the main engine state of the main engine (10). At least one of the main engine states obtained as a calculation result and the main engine state parameter are used to change the model parameter serving as the intra-model variable and update the main engine virtual model (40).
Description
technical field [0001] The invention relates to a main engine monitoring method, a main engine monitoring system, a main engine state prediction system and a navigation state prediction system of a ship using a main engine virtual model. Background technique [0002] With the introduction of EEDI (Energy Efficiency Design Index) rules by the International Maritime Organization (IMO) as functional requirements for ships, it is expected that the miniaturization of main engines mounted on ships will gradually be promoted in order to comply with the rules. On the other hand, IMO also discusses guidelines on the minimum propulsion output that should be available for navigating in severe weather while maintaining safety. Concerns related to the miniaturization of the main engine and safe navigation are considered considered to be the subject of future discussions. [0003] In such future predictions, it is considered that the importance of monitoring the operation status of the h...
