Abstract

The embodiment of the invention provides a capacitance type ship oil tank liquid level measuring device. The device comprises a capacitance detector used for measuring the height of the liquid level of a ship oil tank, a capacitance measuring chip used for converting a capacitance value corresponding to the proportion of oil and air in the capacitance detector into a digital signal, a single-chip microcomputer used for converting the digital signal into the oil amount of the oil tank, and a gas control module used for keeping air pressure intensity in the capacitance detector constant; the capacitance detector is connected with the input end of the capacitance measuring chip, and the output end of the capacitance measuring chip is connected with the single-chip microcomputer. According to the device, the liquid level of the oil tank can be measured when the liquid level of the ship oil tank fluctuates, and the measurement accuracy of the liquid level of the ship oil tank is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic measurement, in particular to a capacitive marine oil tank. Background technique [0002] At present, most merchant ships are driven by diesel engine power plant. In a diesel engine, chemical energy is converted into mechanical energy by injecting fuel into the cylinder for combustion. There are various oil tanks (such as storage tanks and settling tanks) on board to store fuel oil. As we all know, when a ship is sailing at sea, due to the effects of wind, waves, currents, etc., the ship will have different degrees of left and right, front and rear periodic or non-periodic inclinations, which will lead to differences in the liquid level in the ship's oil tank. The degree of fluctuation will cause errors in the measurement results of the measuring instrument. Therefore, it is particularly important to accurately monitor the oil level of the oil tank when the ship is swaying. [0...
