Method for detecting the real-time condition of a container, especially of composite pressuriezed gas containers for vehicles

摘要

The method involves detecting the actual or current condition as regards the aging of a container which is, in predetermined cycles, filled with a pressurised gas and emptied. According to the actual condition, the container undergoes a repeated official test. The amplitude of the pressure cycle i.e. the fill pressure minus the residual pressure before the next filling process is detected. Also the temperature cycles i.e. the max and min temperatures within a predetermined cycle is measured. By means of a suitable computer program the mechanical aging of the container is calculated from the measurements. Also above critical expansion in the circumferential and/or longitudinal direction of the container is detected and taken into account when determining the aging of the container.
