The Research Of Marine Diesel Fuel Consumption Monitoring Instrument

Marine diesel fuel consumption monitoring instrument can make measure and statistics of the overall fuel consumption of the ship effectively, so that companies can acknowledge the ship's fuel consumption and achieve it is sophisticated control and management.It can strengthen the ship's fuel consumption analysis, evaluation and monitoring of ship fuel consumption checks. Marine diesel fuel consumption monitoring instrument can measure the instantaneous flow of marine diesel engine, the cumulative flow, oil temperature and pressure, in accordance with the conditions set by the cumulative measurement of a voyage Flow.This paper introduces us a marine diesel fuel consumption monitoring instrument design. In the paper about the consumption of marine diesel fuel monitoring instrument of two programmes, both the advantages and disadvantages of measurement are compared. This instrument shows the measuring parameters in two different ways; one uses a touch screen with the LCD display measuring parameters, the other is a digital display of measured parameters.This paper involves the consumption of marine diesel fuel monitoring instrument modules circuit theory which includes the theory of the MCU circuit, current / voltage conversion circuit, resistance / voltage conversion circuit voltage analog / digital conversion circuit, photoelectric isolation circuit, analog switches, time Chips, data storage chips, power systems, communications circuits and Modbus protocol.This essay also introduces several commonly used industrial flowmeters, comparing the advantages and disadvantages of various fiowmeters and their measurement for the media, on the marine diesel fuel consumption monitoring instruments in the temperature, pressure, volume flowmeter the instantaneous flow, and the cumulative flow .In order to make more accurate measurements, I also introduced two ways to monitor Marine Diesel Engine fuel. I have completed a marine diesel fuel consumption monitoring instrument design and finished the ralated documents which includes the theoretical graphs,PCB graphs and C program of Controller .The results measured in the laboratory meet the requirements, and the cumulative flow reached 0.2% level, the instantaneous flow to five thousandths of grading error of five thousandths temperature and 0.5%pressure error .
