Since an abnormality is determined based on the opening and closing operations of two or more on-off valves and the gas pressure detected at that time, it is not necessary to attach a special device for abnormality determination and the abnormality is detected during normal operation. Can be determined.
- the abnormality determination unit may include, among the gas pressures detected by the gas pressure detection unit according to the detection when the opening / closing valve according to the opening / closing operation is opened, the detected gas pressure.
- the gas detection means that detects a gas pressure outside a predetermined range from a predetermined value determined based on the above may be a means for determining an abnormality. This makes it possible to more reliably determine the abnormality of the gas pressure detecting means.
- the plurality of gas tanks may be tanks that store hydrogen and store hydrogen therein.
- the gas supply device may be a vehicle-mounted device that supplies hydrogen from the plurality of gas tanks to a hydrogen consuming device mounted on a vehicle.
- hydrogen consuming equipment includes hydrogen engines and fuel cells.
- the on-off valve control means for fully closing the on-off valves of the plurality of gas tanks when the operation of the vehicle is stopped and fully opening the on-off valves of the plurality of gas tanks when the vehicle is started.
- the abnormality determination means is means for determining an abnormality in accordance with the operation of fully opening the on-off valve at the time of starting the vehicle. Can also be. In this case, it is possible to determine the abnormality of the gas pressure detecting means at the time of starting the vehicle.
- the gas supply device when the abnormality determination unit determines an abnormality, the gas supply device may include an abnormality output unit that outputs the abnormality. In this case, it is possible to quickly respond to an abnormality in the gas pressure detecting means.
- FIG. 1 is a configuration diagram schematically showing the configuration of a gas supply device 20 as one embodiment of the present invention mounted on a vehicle.
- FIG. 2 is a flowchart showing an example of an abnormality determination processing routine executed by the electronic control unit 60 of the gas supply device 20 of the embodiment.
- FIG. 1 is a configuration diagram schematically showing the configuration of a gas supply device 20 as one embodiment of the present invention mounted on a vehicle.
- the gas supply device 20 of the embodiment includes a hydrogen storage alloy tank 22 to 28 that can supply hydrogen to a hydrogen consuming device 10 such as a fuel cell or a hydrogen engine mounted on a vehicle;
- An electronic control unit 60 for controlling the supply of hydrogen from the storage alloy tanks 22 to 28 is provided.
- the hydrogen storage alloy tanks 22 to 28 are connected to the hydrogen consuming equipment 10 via supply pipes 40 via branch pipes 32 to 38 connected to the entrances and exits, and are connected to branch pipes 32 to 38.
- the valves are provided with on-off valves 42 to 48 for controlling the supply of hydrogen from the respective hydrogen absorbing alloy tanks 22 to 28.
- the branch pipes 32 to 38 on the tank side with respect to the on-off valves 42 to 48 are provided with pressure sensors 52 to 58 that detect gas pressure in the pipes.
- the electronic control unit 60 is configured as a microprocessor centered on a CPU 62, and includes a ROM 64 storing a processing program, a RAM 66 temporarily storing data, and an input / output port. (Not shown).
- the electronic control unit 60 receives gas pressure P from the pressure sensors 52 to 58 via an input port. Has been entered. Also, from the electronic control unit 60, a drive signal to the actuators 43 to 49 of the on-off valves 42 to 48 and a lighting signal to the indicator 68 are output via the output port. Output.
- FIG. 2 is a flowchart illustrating an example of an abnormality determination processing routine executed by the electronic control unit 60 of the gas supply device 20 of the embodiment. This routine is executed when the vehicle starts.
- the CPU 62 of the electronic control unit 60 first sets each of the on-off valves 42 to 48 detected by the pressure sensors 52 to 58 in the fully closed state.
- the process of reading the gas pressures Pc1 to Pc4 of the hydrogen storage alloy tanks 22 to 28 is executed (step S100).
- the hydrogen storage alloy tanks 22 to 28 such as the gas pressures Pc1 to Pc4
- step S 102 the on-off valves 42 to 48 are fully opened (step S 102), and the on-off valves 42 to 48 detected by the pressure sensors 52 to 58 are set to the gas pressures P o 1 to P o 4 is read (step S104).
- a comparison gas pressure Ps used for judging an abnormality is determined from the read gas pressures Po1 to Po4 (step S106).
- the gas pressure Ps can be determined as an average value by selecting, for example, three values having small deviations from the gas pressures Po1 to Po4.
- each deviation between the gas pressure Ps for comparison and the gas pressures Po1 to Po4 is compared with a threshold value Pr (step S108).
- the threshold value P is set as an error allowable for the pressure sensor or a value slightly larger than the error. If any deviation is larger than the threshold value Pr, the gas related to the deviation is determined. It is determined that an abnormality has occurred in the pressure sensor that has detected the pressure Po, and the corresponding indicator 68 is turned on to output an abnormality (step S110), and this routine is terminated. If the pressure is equal to or smaller than Pr, it is determined that no abnormality is found in any of the pressure sensors 52 to 58, and the routine is terminated.
- any abnormality of the pressure sensors 52 to 58 can be determined.
- No special action is required to determine the abnormality.
- the determination of the abnormality is the same as the opening / closing operation of the on-off valves 42 to 48 normally provided in the hydrogen storage alloy tanks 22 to 28. Since it is performed based on the gas pressure from the pressure sensors 52 to 58, it is not necessary to attach another sensor or the like for determining an abnormality.
- the on-off valves 42 to 48 that are fully closed are fully opened to determine the abnormality of the pressure sensors 52 to 58. If the valves 42 to 48 are fully opened, it is possible to determine the abnormality of the pressure sensors 52 to 58, and the present invention is not limited to starting the vehicle.
- the fully closed on-off valves 42 to 48 are fully opened to determine the abnormality of the pressure sensors 52 to 58.
- Two or more on-off valves out of 2 to 48 may be opened at the same time, and the abnormality of the pressure sensor attached to the branch pipe together with the on-off valve for opening may be determined.
- the gas pressure Ps for comparison may be determined by two or more gas pressures Po having small deviations.
- an abnormality may be determined using one of them as a comparison gas pressure Ps. In this case, it cannot be determined which of the pressure sensors is abnormal, but it can be determined that one of the pressure sensors is abnormal.
- the hydrogen is supplied from the hydrogen storage alloy tanks 22 to 28.
- the hydrogen may be supplied from a hydrogen tank that does not include a hydrogen storage alloy.
- the present invention may be applied to a device that supplies a gas other than hydrogen.
- the gas supply device 20 has been described as being mounted on a vehicle, but may be applied to a device not mounted on a vehicle.
- This gas supply device is used for devices that supply hydrogen to hydrogen engines and fuel cells mounted on vehicles.
