Title:
INTEGRATED MANAGEMENT DEVICE AND METHOD FOR FLUID STORAGE TANK
Document Type and Number:
WIPO Patent Application WO/2021/241910
Kind Code:
A1
Abstract:
The present invention relates to an integrated management technology for fluid storage tank. The integrated management technology may comprise: an optical fiber which has a plurality of optical sensors arranged at equal intervals thereon for sensing temperature and is vertically disposed in the fluid storage tank; an optical fiber analyzer which calculates a temperature of each of the optical sensors from reflective light of light incident to the optical sensor and measures a fluid level on the basis of a temperature change between neighboring optical sensors; and a control part which determines whether an abnormal temperature has occurred, through comparison between a prestored temperature of the optical sensor and a temperature of the optical sensor, calculated from the optical fiber analyzer, calculates an actual amount of inventory on the basis of prestored information of the fluid storage tank and the fluid level calculated from the optical fiber analyzer, determines whether a leakage has occurred, on the basis of a difference between the actual amount of inventory and the prestored management inventory amount, and generates an alarm in case of abnormal temperature or leakage.
