Abstract

An oil tank truck oil leakage early-warning device based on FBG sensors comprises a hose, wherein one end of the hose is inserted into liquid, the other end of the hose extends outside the liquid level, the inner wall of the hose outside the liquid level and the inner wall of the hose inside the liquid are respectively provided with one FBG sensor in an attaching mode, the two FBG sensors are electrically connected with a first coupler and a second coupler respectively, the first coupler and the second coupler are respectively connected with an photoelectric detector respectively, the photoelectric detector is electrically connected with a signal processing module, the signal processing module is electrically connected with an alarm, wavelength shift change amount caused by oil leakage of the two FBG sensors is resolved through analysis of the signal processing module, if wavelength shift difference values change, it can be judged that oil leakage accidents are happening, the alarm is started immediately to give an alarm, real-time detection and alarming on an oil tank truck and other dangerous areas can be achieved, potential safety hazards are eliminated, and the device has the advantages of being high in accuracy and high in instantaneity.

Description

technical field [0001] The invention relates to the technical field of optical fiber FBG sensors, in particular to an oil tank truck oil leakage early warning device based on optical fiber FBG sensors. Background technique [0002] For oil tank trucks, the cause of oil leakage may be due to outdated equipment, collisions, or loose nozzles, etc., and the point of oil leakage is not easy to determine. For the oil leakage warning of tank trucks, temperature monitoring or pressure change detection are generally used, which require accurate measurement data, and then analyze the data, so as to judge whether there is oil leakage. More equipment is required, and the process is relatively complex. In addition, from the perspective of the development and research of fiber Bragg grating FBG (FiberBraggGrating) sensors, fiber optic FBG sensors are rarely studied and used in the early warning of oil spills in oil tankers, especially because they do not need to accurately measure the ch...
