Device and method for measuring fuel capacity of fuel tank for maritime robot

Abstract

The invention relates to a device and method for measuring fuel capacity of a fuel tank for a maritime robot. The device includes a fuel controller, the fuel tank, a liquid level sensor, a temperaturesensor, a density sensor, a liquid level compensation sensor, a liquid level switch and a flow sensor. The liquid level sensor is used for obtaining liquid level information; the temperature sensor,the density sensor and the liquid level compensation sensor are used for obtaining property parameters of fuel; the flow sensor measures the consumption rate of the fuel; the fuel controller processessensor signals. The method includes the steps that the fuel controller corrects the liquid level to figure out a reference liquid level according to a received liquid level of the fuel and a receiveddielectric constant of the fuel, figures out the volume of the fuel in the fuel tank according to a carrier attitude angle and finally figures out the mass of the fuel in the fuel tank according to received fuel density. By using the independent fuel controller and multiple sensors to achieve combined measurement, an influence caused by environmental factors and the mass of the fuel on a measurement result is avoided, the remaining fuel capacity of the fuel tank is measured in real time, and the device and method are also applicable to measurement of the mass and volume of a liquid in an underwater sealing cabin.

Description

technical field [0001] The invention relates to the field of marine robots, in particular to a device and method for measuring the oil quantity of a fuel tank for a marine robot. Background technique [0002] Marine robots are indispensable equipment in the process of marine research and development, and marine robots powered by heat engines need to carry a large amount of fuel to meet functional requirements. The fuel management of marine robots is closely related to the voyage planning of marine robots, and the measurement of the remaining fuel in the fuel tank is the basis of fuel management. [0003] Compared with the oil storage tanks of tens to hundreds of tons of ships, the fuel tanks used by marine robots are often between tens of liters and hundreds of liters, so they are greatly affected by the attitude of the carrier and require high measurement accuracy. At the same time, in the fuel oil management of ships, the remaining fuel volume is often calculated by subtr...
