摘要

A hydrogen gas inventory quantity acquisition system of one embodiment acquires inventory quantities of hydrogen gas in a plurality of offsite hydrogen stations, the system being characterized by being provided with: a log data creation device that, from a plurality of sets of parameter data measured by a plurality of gauges disposed in the hydrogen stations to calculate the inventory quantities of the hydrogen gas in the hydrogen stations, creates log data recording the sets of the parameter data sampled at individual sampling timing set for each hydrogen station together with identification information for each hydrogen station; an inventory quantity computation device that, using the log data, computes the inventory quantity for the hydrogen gas at individual computation timings set for each hydrogen station; a sort processing device that acquires hydrogen gas inventory quantity data for each hydrogen station from the inventory quantity computation device at set time intervals, and performs sort processing on the identification information using the inventory quantities; and a sorted data output device that outputs sorted data that includes the identification information that has been sorted and the inventory quantity data from the sort processing device.
