- off-site ST off-site hydrogen station
- the hydrogen station has a compressor that compresses hydrogen gas to a high pressure in order to rapidly fill the FCV with hydrogen gas, and a plurality of accumulators (multi-stage accumulators) that accumulate the hydrogen gas compressed to high pressure by this compressor. ) Is placed.
- hydrogen gas is charged from the accumulator to the fuel tank by filling the accumulator while switching the accumulator to be used so as to maintain a large difference pressure between the pressure in the accumulator and the pressure in the fuel tank of the FCV.
- each off-site ST workers manually input various information (for example, pressure and temperature) of equipment such as accumulators arranged in the off-site ST to each instrument (for example, pressure gauge and thermometer). I read it from, filled out a data sheet, and sent it to the management organization at the head office. Therefore, a reading error has occurred by the worker. Especially when reading a numerical value from an analog instrument, a large error can occur.
- the instruments installed are different for each off-site ST, and the reading timing is also different. Therefore, there is a problem that it is difficult to accurately grasp the real-time inventory amount of hydrogen gas stocked in each off-site ST from the obtained data. As a result, there was no choice but to rely on empirical rules as to when and how much hydrogen gas should be transported to which off-site ST. Therefore, it is desirable to grasp the inventory amount of hydrogen gas in each off-site ST with high accuracy.
- one aspect of the present invention provides a method, an apparatus, and a system capable of obtaining the inventory amount of hydrogen gas of each off-site ST with high accuracy.
- the hydrogen gas inventory acquisition system is A hydrogen gas inventory acquisition system that acquires hydrogen gas inventory at multiple off-site hydrogen stations. Sampling at the individual sampling timing set for each hydrogen station from multiple parameter data measured by multiple instruments arranged at each hydrogen station to calculate the amount of hydrogen gas in stock at each hydrogen station.
- a log data creation device that creates log data that records each of the parameter data that has been created together with the identification information of each hydrogen station.
- An inventory amount calculation device that calculates the inventory amount of hydrogen gas at the individual calculation timing set for each hydrogen station using the log data, and
- a sort processing device that acquires hydrogen gas inventory amount data at each hydrogen station from the inventory amount calculation device for each set time zone and sorts the identification information using the inventory amount.
- a sort data output device that outputs sort data including the sort-processed identification information and the stock amount data from the sort processing device, and It is characterized by having.
- each of the hydrogen stations belongs to any one of a plurality of groups, For each group, a group-specific inventory amount creation device that aggregates the inventory amount of each hydrogen station belonging to the group and creates group-specific inventory amount data.
- An inventory amount data transmission device for each group that transmits the inventory amount data for each group to each hydrogen station, It is preferable to further provide.
- each hydrogen station has an accumulator for accumulating hydrogen gas.
- the plurality of parameter data include pressure data of hydrogen gas in the accumulator and temperature data that can be estimated to be the temperature of hydrogen gas in the accumulator.
- each hydrogen station has a compressor that compresses hydrogen gas.
- the individual calculation timing is preferably set to the operation stop time of the compressor.
- the individual calculation timing is the time when the supply of hydrogen gas to the fuel cell vehicle is completed.
- each of the hydrogen stations includes an intermediate accumulator that accumulates hydrogen gas unloaded from a trailer that transports hydrogen gas, and a high-pressure accumulator that accumulates hydrogen gas compressed to a higher pressure than the intermediate accumulator.
- an intermediate accumulator that accumulates hydrogen gas unloaded from a trailer that transports hydrogen gas
- a high-pressure accumulator that accumulates hydrogen gas compressed to a higher pressure than the intermediate accumulator.
- the log data creation device is arranged in each hydrogen station, the inventory amount calculation device is arranged in a data center different from each hydrogen station, and the log data creation device and the inventory amount calculation device are networked. It is preferable that they are connected via.
- the log data creation device and the inventory amount calculation device are arranged at each hydrogen station.
- the method for obtaining the hydrogen gas inventory amount is This is a hydrogen gas inventory acquisition method for acquiring hydrogen gas inventory at multiple off-site hydrogen stations. Sampling at the individual sampling timing set for each hydrogen station from multiple parameter data measured by multiple instruments arranged at each hydrogen station to calculate the amount of hydrogen gas in stock at each hydrogen station. A log data creation process for creating log data in which each parameter data is recorded together with identification information of each hydrogen station, and Using the log data, the inventory amount calculation process for calculating the inventory amount of hydrogen gas at the individual calculation timing set for each hydrogen station, and the inventory amount calculation process. Sort processing that acquires hydrogen gas inventory amount data at each hydrogen station based on the inventory amount calculated in the inventory amount calculation step for each set time zone, and sorts the identification information using the inventory amount. Process and A sort data output step for outputting sort data including the sort-processed identification information and the inventory amount data, and It is characterized by having.
- the hydrogen gas inventory amount acquisition device of one aspect of the present invention is A hydrogen gas inventory acquisition device that acquires the inventory of hydrogen gas at multiple off-site hydrogen stations. Sampling at the individual sampling timing set for each hydrogen station from multiple parameter data measured by multiple instruments arranged at each hydrogen station to calculate the amount of hydrogen gas in stock at each hydrogen station.

As shown, it will rise further. Along with this, the pressure of the accumulator in the 2nd bank (graph indicated by "2nd") gradually decreases. Then, when the time T2 elapses from the start of filling when the lower limit pressure for use of the 2nd bank is reached, the accumulator used for the accumulator to be the 3rd bank is switched from the accumulator of the 2nd bank.
- the residual pressure of the 3rd bank accumulator is larger than that of the 2nd bank accumulator used up to time T2 (the differential pressure between the fuel tank and the fuel tank is larger), so that the filling speed can be maintained at a high speed.
- the hydrogen fuel accumulated in the accumulator of the 3rd bank by the differential pressure between the accumulator of the 3rd bank and the fuel tank moves to the fuel tank side at the adjusted filling speed, and the pressure of the fuel tank is the dotted line Pt.

- hydrogen gas is accumulated in the trailer 10, the intermediate accumulator 30, and the high-pressure accumulator 40. Therefore, the inventory amount of hydrogen gas at each hydrogen station 102 is the total amount (kg) of hydrogen gas accumulated in these.
- Each accumulator amount (weight of hydrogen gas) can be obtained by the PVT method (volume method) using the capacity (volume) V of the accumulator container, the pressure P, and the temperature T.

I was sending it to the institution. Therefore, a reading error has occurred by each worker. Especially when reading a numerical value from an analog instrument, a large error can occur.
- each off-site ST may have different instruments installed, or the timing of reading information from each instrument may be different. Therefore, there is a problem that it is difficult to accurately grasp the inventory amount of hydrogen gas in each off-site ST from the obtained data (information read from each instrument).
