Abstract
A measured value acquisition unit acquires a measured value of a pressure of a hydrogen tank of each of a plurality of work vehicles, on which the hydrogen tanks are mounted, and a measured value of a pressure of a pressure accumulator of a hydrogen station where the hydrogen tanks are filled with a hydrogen gas. An estimation unit estimates a value related to a filling time of the hydrogen gas at the hydrogen station for the plurality of work vehicles based on the measured values of the pressures. The determination unit determines filling timings of the hydrogen gas for the plurality of work vehicles such that the total of the filling times is minimized based on the value related to the filling time.
Claims20
A work vehicle management device comprising:
- a measured value acquisition unit configured to acquire a measured value of a pressure of a hydrogen tank of each of a plurality of work vehicles, on which the hydrogen tanks are mounted, and a measured value of a pressure of a pressure accumulator of a hydrogen station where the hydrogen tanks are filled with a hydrogen gas;
- and
- a determination unit configured to determine filling timings or filling order of the hydrogen gas for the plurality of work vehicles based on the measured values of the pressures.
A system comprising:
- a plurality of work vehicles including a hydrogen tank, a pressure gauge that acquires a measured value of a pressure of the hydrogen tank, and a communication device that transmits the measured value of the pressure of the hydrogen tank;
- a hydrogen station including a pressure accumulator that raises a pressure of a hydrogen gas to a predetermined pressure to be filled with the hydrogen gas, a pressure gauge that acquires a measured value of a pressure of the pressure accumulator, and a communication device that transmits the measured value of the pressure of the pressure accumulator;
- and
- a management device including a communication device that receives the measured value of the pressure of the hydrogen tank and the measured value of the pressure of the pressure accumulator and a determination unit that determines filling timings or filling order of the hydrogen gas for the plurality of work vehicles based on the measured value of each of the pressure of the hydrogen tank and the pressure of the pressure accumulator.
A work vehicle management method comprising:
- a step of acquiring a measured value of a pressure of a hydrogen tank of each of a plurality of work vehicles, on which the hydrogen tanks are mounted, and a measured value of a pressure of a pressure accumulator of a hydrogen station where the hydrogen tanks are filled with a hydrogen gas;
- and
- a step of determining filling timings or filling order of the hydrogen gas for the plurality of work vehicles based on the measured values of the pressures.
