APPARATUS FOR MANAGING HISTORY OF PRESSURE VESSEL AND METHOD FOR FILING PRESSURE VESSEL

摘要

The technical problem of the present invention is to provide an apparatus for managing a history of a pressure vessel, which facilitates the history management of a pressure vessel and thereby can prevent a fire or explosion from being caused by water leakage, and a method for filling the pressure vessel. To solve the above-mentioned technical problem, the apparatus for managing a history of a pressure vessel comprises a history management unit comprising: a strain measurement device for measuring a strain, the strain measurement device being mounted on the surface of the pressure vessel;a pressure gauge for measuring the pressure of gas which is filled in the pressure vessel, the pressure gauge being mounted in the pressure vessel; a unique identification unit formed such that unique information of the pressure vessel can be input and output through the unique identification unit; and a control and processing unit for comparing a measured stress-strain curve with a reference stress-strain curve unique to the material of the pressure vessel and displaying a difference value therebetween, wherein the measured stress-strain curve is derived from the strain measured by the strain measurement device and a stress calculated by the pressure input from the pressure gauge, and the reference stress-strain curve is input by the unique identification unit. The apparatus for managing a history of a pressure vessel according to the invention previously recognizes, through the unique identification unit of the corresponding pressure vessel, the number of times filling has been performed, and notifies the user of a dangerous condition by sending a warning signal when the number of cycles to fatigue failure, specified for each material, is exceeded.
