Abstract
As a result of the systematic studies carried out, the structure of the information model of a system for determining the rheological characteristics of ship’s technical liquids has been developed. The performed research has shown the possibility of building computer systems for determining the characteristics of ship's technical fluids and their operational control. The model can be used for the further construction on its basis of automated systems for the study of ship's technical fluids, as well as control of their preparation before being supplied to the fuel equipment. Integration of the developed model into the overall structure of the vessel's functioning was carried out, on the basis of which an expanded information model of the system for determining and controlling the rheological characteristics of ship's technical liquids was developed. The developed system allows automatic measurements of rheological characteristics and transfer them to an intelligent data collection and control module for further automated decision making on the basis of available technical data on operating modes of fuel equipment and compliance with the characteristics of ship's technical fluids for correcting the parameters of the system of their preparation. A method for automatic determination and regulation of the rheological characteristics of ship technical fluids is proposed, which allows using it in computer systems with the possibility of changing the parameters of the system operation in real time and online modes. This method involves improving the efficiency of fuel preparation and reducing the amount of harmful emissions to the environment. There is no need to involve the ship mechanic in controlling the parameters at all stages of the operation of fuel equipment. On the basis of the developed detailed information model of the system for determining and controlling the rheological characteristics of ship’s technical liquids, an information model of a laboratory research system for determining the rheological characteristics of ship’s technical liquids has been developed. It allows the simulation of its operation and the fuel characteristics in accordance with the predicted frequency-temperature mode of the engine. The data obtained will allow further effective control of the quality of fuel preparation before being fed to the internal combustion engine nozzles. The block diagrams of algorithms for determining and regulating the rheological parameters of ship technical fluids based on the proposed method for automatic determination and regulation of the rheological characteristics of ship technical liquids are developed and ensure that all prerequisites are fulfilled for the hardware and software implementation of the computer system for determining and regulating the rheological parameters of vessel technical liquids.
