Abstract

This invention relates to an operating system, operating method, and recording medium for mobile hydrogen stations. The operating server of this invention utilizes multiple MSTs (Mobile Storage Stations). The operating server includes: a receiving unit that receives filling requests specifying at least a filling time and filling location; a planning unit that generates allocation plan information for the multiple MSTs based on the filling requests received by the receiving unit; and an allocation unit that performs allocation processing for the multiple MSTs based on the allocation plan information. If there are not two or more MSTs without a scheduled allocation at the filling time specified in the filling request, the receiving unit rejects the filling request. If an allocated or scheduled MST malfunctions, the allocation unit performs allocation processing to replace the malfunctioning MST with an MST that was not scheduled for allocation at the filling time assigned to the malfunctioning MST.

Description

Technical Field

[0001] This invention relates to the operating system, operating method, and recording medium for mobile hydrogen stations. Background Technology

[0002] Japanese Patent Application Publication No. 2017-194745 discloses a deployment planning technology for mobile hydrogen stations used to fill hydrogen tanks in vehicles such as fuel cell vehicles (FCVs). Specifically, Japanese Patent Application Publication No. 2017-194745 points out that if mobile hydrogen stations are dispatched to hydrogen filling locations designated by FCV users based on reservations from users, it is difficult to utilize mobile hydrogen stations efficiently. Moreover, in Japanese Patent Application Publication No. 2017-194745, as a deployment planning method for mobile hydrogen stations in a region including multiple areas, (1) the estimated hydrogen demand of each region within a specified time period is calculated, and (2) based on the estimated hydrogen demand of each region, the region where the mobile hydrogen station is deployed and the time period for deploying the mobile hydrogen station to that region are determined.

[0003] Currently, in areas with few fixed hydrogen stations, a limited number of mobile hydrogen stations are shared across multiple filling locations on a time-sharing basis. If any of the mobile hydrogen stations malfunctions and cannot provide filling services at the designated filling location, users have to change their reservations and go to other filling locations, resulting in significant time and financial burdens for them.

[0004] In contrast, Japanese Patent Application Publication No. 2017-194745 formulates a configuration plan for mobile hydrogen stations based on the assumption that no mobile hydrogen stations will malfunction, and therefore cannot cope with the malfunction of mobile hydrogen stations. Summary of the Invention

[0005] The purpose of this invention is to provide an application technology that can cope with the failure of mobile hydrogen stations.

[0006] According to a first aspect of this invention, an application system is provided that utilizes multiple mobile hydrogen stations. The system includes: a receiving unit that receives filling requests specifying at least a filling time and location; a planning unit that generates deployment plan information for the multiple mobile hydrogen stations based on the filling requests received by the receiving unit; and an deployment unit that performs deployment processing for the multiple mobile hydrogen stations based on the deployment plan information. If, during the filling time specified in the filling request, there are no two or more mobile hydrogen stations that are not scheduled to be deployed, the receiving unit rejects the filling request. If a deployed or scheduled mobile hydrogen station malfunctions, the deployment unit performs deployment processing, replacing the malfunctioning mobile hydrogen station with a mobile hydrogen station that was not scheduled to be deployed during the filling time assigned to the malfunctioning mobile hydrogen station. Based on the above structure, an application technology capable of handling mobile hydrogen station malfunctions is realized.

[0007] Preferably, in the event that a deployed mobile hydrogen station malfunctions and multiple mobile hydrogen stations are on standby, the deployment unit performs a deployment process that replaces the malfunctioning mobile hydrogen station with the mobile hydrogen station closest to the filling location assigned to the malfunctioning mobile hydrogen station among the multiple standby mobile hydrogen stations. Based on this structure, deployment costs can be reduced.

[0008] Preferably, in the event that a mobile hydrogen station that has been equipped malfunctions and multiple mobile hydrogen stations are on standby, the aforementioned equipment unit performs an equipment allocation process, replacing the malfunctioning mobile hydrogen station with the mobile hydrogen station among the multiple standby mobile hydrogen stations that has the largest filling capacity. Based on the above structure, a mobile hydrogen station with a large filling capacity is equipped at the filling location assigned to the malfunctioning mobile hydrogen station.

[0009] Preferably, in the event that a mobile hydrogen station that has been equipped malfunctions and there are no mobile hydrogen stations on standby, the equipment unit performs an equipment allocation process, causing mobile hydrogen stations that have been allocated to other filling sites to be allocated to the filling site assigned to the malfunctioning mobile hydrogen station in a time-sharing manner. Based on the above structure, filling services at the aforementioned filling sites can continue without canceling already received filling requests.

[0010] Preferably, if a pre-assigned mobile hydrogen station malfunctions, and multiple unassigned mobile hydrogen stations exist during the filling time assigned to the malfunctioning station, the planning department updates the deployment plan information. Instead of the malfunctioning station, the department deploys the mobile hydrogen station closest to the filling location of the malfunctioning station during the time period before or after the filling time assigned to the malfunctioning station. Based on this structure, deployment costs can be reduced.

[0011] Preferably, if a scheduled mobile hydrogen station malfunctions and there is no scheduled mobile hydrogen station available during the filling time assigned to the malfunctioning station, the planning department updates the allocation plan information so that mobile hydrogen stations scheduled to be allocated to other filling locations during that filling time are also allocated to the filling location assigned to the malfunctioning mobile hydrogen station on a time-sharing basis. Based on this structure, filling services at the filling locations can continue without canceling already received filling requests.

[0012] Preferably, the above-described system also utilizes a fixed hydrogen station. In the event of a malfunction in the fixed hydrogen station, the equipment unit performs equipment deployment by placing a standby mobile hydrogen station at or near the fixed hydrogen station. Based on this structure, refilling services at the fixed hydrogen station can continue.

[0013] According to a second aspect of this invention, an application method is provided, which utilizes multiple mobile hydrogen stations. The method includes: a receiving step, accepting a filling request specifying at least a filling time and location; a planning step, generating deployment plan information for the multiple mobile hydrogen stations based on the filling request received by the receiving unit; and a deployment step, performing deployment processing for the multiple mobile hydrogen stations based on the deployment plan information. In the receiving step, if there are no two or more mobile hydrogen stations without a pre-determined deployment time specified in the filling request, the filling request is rejected. In the deployment step, if a deployed or pre-determined mobile hydrogen station malfunctions, deployment processing is performed, replacing the malfunctioning mobile hydrogen station with a mobile hydrogen station that was not pre-determined during the filling time assigned to the malfunctioning mobile hydrogen station. Based on the above method, an application technology capable of handling mobile hydrogen station malfunctions is realized.

[0014] Preferably, a recording medium is provided, which records a program that enables a computer to function as the aforementioned application system or to execute the aforementioned application method.

[0015] According to the present invention, a mobile hydrogen station application technology is realized that can also cope with the failure of mobile hydrogen stations.

[0023] Figure 7 It utilizes the server's control flow. Detailed Implementation

[0024] The following is for reference Figures 1 to 7 The embodiments of the invention described in this application will be explained.

[0025] Figure 1 A simplified structural diagram of hydrogen supply system 1 is shown. (Example:) Figure 1 As shown, the hydrogen supply system 1 includes an application server 2, multiple user terminals 3 (hereinafter referred to as UE3), multiple mobile hydrogen stations 4 (hereinafter referred to as MST4), and a fixed hydrogen station 5 (hereinafter referred to as CST5).

[0026] Multiple UE3s are configured to communicate bidirectionally with application server 2 via, for example, a WAN (Wide Area Network). Similarly, multiple MST4s and CST5s are configured to communicate bidirectionally with application server 2 via, for example, a WAN.

[0027] UE3 is a terminal for use by users of hydrogen supply system 1, typically a user's information processing terminal or a vehicle navigation system installed in the user's fuel cell vehicle. Information processing terminals typically include desktop computers, laptops, tablet PCs, PDAs, and smartphones.

[0028] MST4 is a mobile hydrogen station with a hydrogen filling unit mounted on the cargo platform of a mobile truck. The hydrogen filling unit typically includes a compressor, an accumulator, and a refueling device.

[0029] CST5 is a stationary hydrogen station equipped with a non-movable hydrogen filling device. A typical CST5 includes a compressor, accumulator, and refueling unit. CST5 can be either an on-site or off-site stationary hydrogen station. An on-site stationary hydrogen station has its own hydrogen production unit. An off-site stationary hydrogen station supplies hydrogen from a centralized hydrogen production facility via land-based transportation.

[0030] Multiple MST4 and CST5 units can also be related as mother and daughter. That is, the hydrogen filling device of multiple MST4 units can also receive hydrogen supply through CST5.

[0031] Application server 2 is a specific example of an application system that uses multiple MST4 and CST5. Application server 2 receives fill requests from UE3 and configures MST4 according to the fill requests.

[0032] Hydrogen supply system 1 is typically set up according to each administrative district. Furthermore, each MST4 is temporarily deployed at any of several locations within the administrative district. These locations typically include existing gas stations, municipal service facilities, supermarkets, and large retail facilities such as appliance stores. Each location is suitable for deploying an MST4 and generally requires prior review and registration in accordance with relevant regulations. By utilizing multiple MST4s, hydrogen supply system 1 can flexibly meet the hydrogen refilling needs of the administrative district.

[0033] Next, refer to Figures 2-4 The use of server 2 will be explained. Figure 2 This is a functional block diagram using server 2. For example... Figure 2 As shown, the server 2 includes a CPU 2a (Central Processing Unit) as a central processing unit, a RAM 2b (Random Access Memory) that can be freely read and written, and a ROM 2c (Read Only Memory) for dedicated reading. Furthermore, the CPU 2a reads and executes the control program stored in the ROM 2c, thereby controlling the hardware such as the CPU 2a to function as the receiving unit 10, the planning unit 11, and the equipment unit 12.

[0034] The receiving unit 10 receives filling requests from each UE3. The filling request specifies at least the filling time and filling location. The filling request may also specify the filling amount.

[0035] The filling time refers to the desired time for hydrogen to be filled into the fuel cell vehicle owned by the user corresponding to UE3. In this embodiment, the filling time includes the desired date and the desired time period. The desired time period is typically expressed as AM or PM. However, it can also be expressed as hours and minutes. Furthermore, while the user desires hydrogen to be filled into the fuel cell vehicle in this embodiment, it could also desire hydrogen to be filled into a so-called hydrogen vehicle. Here, a fuel cell vehicle is a vehicle that uses hydrogen from a hydrogen fuel tank to generate electricity and uses that electricity to drive a motor. A hydrogen vehicle, on the other hand, is a vehicle that uses hydrogen from a hydrogen fuel tank to burn hydrogen in an engine such as a reciprocating engine or a rotary engine to generate power.

[0036] A filling location is a place where hydrogen is intended to be filled into the fuel cell vehicles owned by the user corresponding to UE3. That is, a filling location is any one of the multiple locations within the administrative area designated by the hydrogen supply system 1.

[0037] The filling amount refers to the amount of hydrogen that is desired to be filled into the fuel cell vehicles owned by the user corresponding to UE3. The filling request may also be information specifying the number of vehicles to be filled instead of specifying the filling amount. That is, when the filling request is information specifying the number of vehicles to be filled instead of the filling amount, the receiving unit 10 can calculate the filling amount by multiplying the number of vehicles to be filled by the known filling amount per vehicle.

[0038] In this embodiment, the fill request only specifies the fill time and fill location.

[0039] The planning unit 11 generates multiple MST4 configuration plan information based on the filling requests received by the receiving unit 10.

[0040] Please refer to this. Figure 3 .exist Figure 3 The table below shows the filling time and location of the filling requests received by the receiving unit 10. For example, in... Figure 3 In this context, the number "1" indicates the initial fill request received by the receiving unit 10, with a fill time of "2021 / 8 / 4AM" and a fill location of "Location 2". Similarly, the number "21" represents the 21st fill request received by the receiving unit 10, with a fill time of "2021 / 8 / 5PM" and a fill location of "Location 5". Furthermore, Figure 3 The table shown is merely a description of the content of the fill requests received sequentially by the receiving unit 10. Whether or not... Figure 3 The table is stored in RAM4b of MST4 without restriction.

[0041] Next, please refer to Figure 4 . Figure 4The allocation plan information generated by Planning Department 11 is shown in tabular form. The allocation plan information is based on the filling time and location assigned to each MST4. For example, MST4 for No. 1 is scheduled to be allocated to "Location 2" at 4 AM on August 4, 2021. Additionally, MST4 for No. 4 is scheduled to be allocated to "Location 6" at 5 PM on August 4, 2021. Planning Department 11 aims to meet... Figure 3 The method shown in the populate request is used to formulate multiple MST4 configuration plans and generate configuration plan information as the result.

[0042] In addition, Figure 4 In the equipment plan information shown, MST4 of No. 1 has the highest operating rate, while MST4 of No. 5 has the lowest operating rate. The planning department 11 can also generate equipment plan information in a way that makes the operating rates of multiple MST4s as even as possible.

[0043] The equipment unit 12 performs equipment processing for multiple MST4s based on equipment plan information. Here, equipment processing refers to the process used to configure equipment according to... Figure 4 The equipment plan information shown indicates that multiple MST4 processes are available.

[0044] As part of the configuration process, configuration plan information may be sent to multiple MST4s. In this case, the configuration plan information is output to a display set up on each MST4. The operator of each MST4 configures the MST4 by referring to the configuration plan information output to the display. Here, the operator is typically a driver.

[0045] Additionally, as part of the configuration process, configuration plan information may be output to the display of application server 2. The operator of application server 2 then issues configuration instructions to the operators of each MST4 based on the configuration plan information output to the display of application server 2.

[0046] In addition, if each MST4 is installed in a truck capable of autonomous driving, as part of the equipment process, driving instructions based on equipment plan information are sent to the autonomous driving control unit of each MST4.

[0047] Furthermore, if there are not two or more units without the pre-assigned MST4 within the filling time specified in the filling request, the receiving unit 10 rejects the filling request. For example, in Figure 3 In the middle, the fill time for fill request No. 21 is "2021 / 8 / 5PM". (Referring to...) Figure 4 Regarding the equipment plan information, on August 5, 2021, the only new MST4 unit available for the designated "Location 5" in the fill request for No. 21, which was not originally scheduled to be equipped, was the MST4 unit for No. 5, i.e., only one unit. Therefore, the receiving department 10 rejected the request. Figure 3The filling request shown is No. 21. Specifically, the receiving unit 10 sends a message to UE3, the sender of the filling request, indicating that the filling request is rejected.

[0048] Alternatively, the receiving unit 10 may not only reject the filling request of No. 21 as described above, but also provide the UE3, which is the sender of the filling request, with other filling time options such as "2021 / 8 / 5AM", and propose any one or more of "site 4", "site 2", "site 3" and "site 6" that are equipped with a predetermined filling location at "2021 / 8 / 5PM".

[0049] Thus, for receiving unit 10, at least one unit is not included in the equipment reservation at all times, but is reserved as a backup. Therefore, in the event that an equipped or reserved MST4 fails, other MST4s can perform the filling service reserved for that MST4.

[0050] That is, if a malfunction occurs in an MST4 that has been equipped or is scheduled to be equipped, the equipment unit 12 performs an equipment process, which replaces the malfunctioning MST4 with an MST4 that was not scheduled to be equipped during the filling time assigned to the malfunctioning MST4.

[0051] For example, if the MST4 No.2, which was equipped to "Location 6" on "August 4, 2021", malfunctions in "Location 6", the equipment unit 12 will replace the MST4 No.2 with the MST4 No.5 and equip "Location 6".

[0052] Furthermore, for example, if the MST4 No. 2, which was equipped to "Location 3" on "August 5, 2021", malfunctions, the equipment unit 12 will replace the MST4 No. 2 and instead equip "Location 3" with any one of the MST4 No. 3 to No. 5. In this case, the equipment unit 12 typically replaces the MST4 No. 2 and equips "Location 3" with the MST4 No. 3 to No. 5 that is closest to "Location 3". As a result, the total travel distance when equipping other MST4s as a backup for the malfunctioning MST4 is minimized, thus reducing equipment costs.

[0053] The aforementioned application server 2 can be implemented by a single device or by distributed processing by multiple devices capable of communicating data with each other.

[0054] Next, refer to Figure 5 Each MST4 is explained. Figure 5 These are the function block diagrams for each MST4. For example... Figure 5 As shown, each MST4 includes a CPU4a (Central Processing Unit) as a central processing unit, a RAM4b (Random Access Memory) for free reading and writing, and a dedicated ROM4c (Read Only Memory). Furthermore, the CPU4a reads and executes the control program stored in the ROM4b, thereby controlling the CPU4a and other hardware to function as a current location information acquisition unit 20, a hydrogen inventory information acquisition unit 21, an equipment plan information output unit 22, and a fault detection unit 23. Each MST4 also includes a GPS module 24 and a display 25.

[0055] The current location information acquisition unit 20 uses the GPS module 24 to acquire the current location information of MST4. The GPS module 24 is a specific example of a GNSS module (Global Navigation Satellite System). Specific examples of GNSS modules include the GLONASS module (Global Navigation Satellite System), the Galileo module, the BeiDou module, and the QZSS module (Quasi-Zenith Satellite System). The current location information acquisition unit 20 periodically transmits the acquired current location information to the application server 2.

[0056] The hydrogen inventory information acquisition unit 21 acquires hydrogen inventory information indicating the amount of hydrogen in the hydrogen filling device installed in the MST4. Specifically, the hydrogen inventory information acquisition unit 21 measures the pressure and temperature inside the accumulator of the hydrogen filling device and calculates the amount of hydrogen based on the measured data. The hydrogen inventory information acquisition unit 21 periodically sends the acquired hydrogen inventory information to the application server 2.

[0057] The equipment plan information output unit 22 outputs the equipment plan information received from the application server 2 to the display 25.

[0058] The fault detection unit 23 detects faults in the MST4. Typical faults in the MST4 include malfunctions in the hydrogen filling unit or in the truck carrying the MST4. If the fault detection unit 23 detects a fault in the MST4, it sends fault information indicating the MST4 fault, along with the MST4's identification information, to the application server 2. The fault information may also include information identifying the structural component within the MST4 that has malfunctioned.

[0059] Next, refer to Figure 6 CST5 will be explained. Figure 6 This is the function block diagram of CST5. (Example) Figure 6As shown, the CST5 includes a CPU5a (Central Processing Unit) as a central processing unit, a RAM5b (Random Access Memory) that can be freely read and written, and a ROM5c (Read Only Memory) for dedicated reading. Furthermore, the CPU5a reads and executes the control program stored in the ROM5b, thereby controlling the hardware such as the CPU5a to function as the fault detection unit 30.

[0060] The fault detection unit 30 detects faults in CST5. A typical fault in CST5 is a fault in the hydrogen filling device. If the fault detection unit 30 detects a fault in CST5, it sends fault information indicating the fault in CST5, along with CST5 identification information, to the application server 2. The fault information may also include information identifying the structural element within the CST5 that has malfunctioned.

[0061] Next, refer to Figure 7 The operation of hydrogen supply system 1 is described.

[0062] S100:

[0063] The receiving unit 10 receives a filling request from UE3.

[0064] S110:

[0065] Next, the Ministry of Acceptance 10 references Figure 4 The receiving unit 10 checks the equipment plan information and determines whether there are two or more unequipped MST4 (idle MST4) units within the filling time specified in the filling request received by the receiving unit 10. If there are two or more such units, the receiving unit 10 proceeds to S120. If there are no two or more such units, the receiving unit 10 proceeds to S130.

[0066] S120:

[0067] The planning unit 11 generates multiple MST4 configuration plan information based on the filling request received by the receiving unit 10, and initiates processing to S140.

[0068] S130:

[0069] The receiving unit 10 rejects the filling request, sends a message to UE3, the sender of the filling request, indicating that the filling request has been rejected, and initiates the process to S140.

[0070] S140:

[0071] The planning unit 11 determines whether the MST4, which is scheduled to be equipped, has malfunctioned. If it is determined that the MST4, which is scheduled to be equipped, has malfunctioned, the planning unit 11 proceeds to step S150. On the other hand, if it is determined that the MST4, which is scheduled to be equipped, has not malfunctioned, the planning unit 11 proceeds to step S200.

[0072] S150:

[0073] In the event that a scheduled MST4 malfunctions, the Planning Department 11 re-plans the deployment of multiple MST4s and updates the deployment plan information.

[0074] For example, if a scheduled MST4 fails and multiple MST4s are not scheduled to be equipped during the filling time assigned to the failed MST4, the planning department 11 updates the equipment plan information so that, instead of the failed MST4, the MST4 that is closest to the filling location of the failed MST4 during the time period before or after the filling time assigned to the failed MST4 is equipped.

[0075] exist Figure 4 In the example, MST4 No. 4, scheduled to be delivered to "Location 1" at 6 PM on August 5, 2021, malfunctioned late at night on August 5, 2021. Furthermore, no MST4 was delivered at 6 PM on August 6, 2021, the designated filler day for MST4 No. 4; instead, MST4 No. 2 and MST4 No. 3 were delivered. MST4 No. 2 and MST4 No. 3 were scheduled to be delivered to "Location 6" and "Location 2" respectively at 6 AM on August 6, 2021, a time period preceding "6 PM on August 6, 2021." Additionally, "Location 6" is closer to "Location 1" than "Location 2." In this case, the planning department 11 updates the delivery schedule information, causing MST4 No. 4, originally scheduled to be delivered to "Location 1" at 6 PM on August 6, 2021, to be delivered to "Location 1" as MST4 No. 2 instead. Therefore, compared to the case of replacing the No.3 with the MST4, the equipment cost can be reduced.

[0076] Additionally, for example, if a scheduled MST4 fails and there is no scheduled MST4 available during the fill time assigned to the failed MST4, the planning department 11 updates the allocation plan information, causing the MST4 scheduled to be allocated to other fill locations during that fill time to be allocated to the fill location assigned to the failed MST4 in a time-sharing manner. In this case, multiple fill locations are assigned to one MST4 within the same time period (e.g., "2021 / 8 / 6PM"), requiring one MST4 to move between multiple fill locations during that time period. This avoids the situation where already received fill requests have to be cancelled.

[0077] S200:

[0078] The equipment unit 12 performs intraday equipment processing for multiple MST4s based on equipment plan information.

[0079] S210:

[0080] The equipment unit 12 determines whether the equipped MST4 has malfunctioned. If the equipped MST4 is determined to have malfunctioned, the equipment unit 12 proceeds to step S220. On the other hand, if the equipped MST4 is determined not to have malfunctioned, the equipment unit 12 proceeds to step S300.

[0081] S220:

[0082] The equipment unit 12 determines whether there is a standby MST4. A standby MST4 refers to an MST4 that is not equipped in any current filling location and is waiting to be equipped in the next predetermined location. If it is determined that there is a standby MST4, the equipment unit 12 proceeds to S230. On the other hand, if it is determined that there is no standby MST4, the equipment unit 12 proceeds to S240.

[0083] S230:

[0084] The equipment unit 12 determines whether there are multiple MST4 units in standby mode. If it determines that there are multiple MST4 units in standby mode, the equipment unit 12 proceeds to step S250. On the other hand, if it determines that there is only one MST4 unit in standby mode, the equipment unit 12 proceeds to step S260.

[0085] S240:

[0086] The equipment unit 12 performs the equipment processing by also time-sharing the equipment locations assigned to the malfunctioning MST4 with the equipment locations that have already been equipped with other equipment locations. This avoids the situation where already received equipment requests must be cancelled. Furthermore, the equipment unit 12 proceeds to step S300.

[0087] S250:

[0088] The equipment unit 12 selects an MST4 from a plurality of MST4s in standby mode to replace the malfunctioning MST4.

[0089] For example, the equipment unit 12 selects the MST4 among the multiple MST4s in standby that is closest to the filling location assigned to the faulty MST4. According to this configuration, the replacement MST4 can quickly reach the filling location assigned to the faulty MST4. Furthermore, equipment costs can be reduced.

[0090] Alternatively, the equipment unit 12 can select the MST4 with the largest fillable quantity from among the multiple MST4s in standby mode. According to this configuration, an MST4 with a large fillable quantity can be provided to the filling location assigned to the malfunctioning MST4.

[0091] Alternatively, the equipment unit 12 can select the MST4 with the lowest operating rate among the multiple MST4s in standby mode. This configuration allows for the equalization of the operating rates of the multiple MST4s.

[0092] S260:

[0093] The configuration unit 12 performs configuration processing by configuring an MST4 selected from multiple MST4s in standby mode, replacing the malfunctioning MST4. Furthermore, the configuration unit 12 initiates processing in step S300.

[0094] S300:

[0095] Next, the equipment unit 12 determines whether CST5 has malfunctioned. If CST5 is determined to be malfunctioning, the equipment unit 12 proceeds to step S310. On the other hand, if CST5 is determined not to be malfunctioning, the equipment unit 12 terminates the process.

[0096] S310:

[0097] The equipment unit 12 determines whether there is a standby MST4. If it determines that there is a standby MST4, the equipment unit 12 proceeds to process S320. On the other hand, if it determines that there is no standby MST4, the equipment unit 12 proceeds to process S330.

[0098] S320:

[0099] The equipment unit 12 performs the equipment process by equipping the standby MST4 to or near CST5. This allows the filling service in CST5 to continue. Then, the equipment unit 12 terminates the process.

[0100] Alternatively, the configuration unit 12 can be configured to equip any one of the multiple standby MST4 units to the faulty CST5 or its vicinity whenever such a unit is available. According to this configuration, given that MST4s fail more frequently than CST5s, at least one spare MST4 can be maintained. However, the configuration unit 12 can also perform the configuration process of equipping the only standby MST4 to the CST5 or its vicinity.

[0101] S330:

[0102] The equipment unit 12 performs the equipment allocation process by also allocating the MST4 time-sharing site, which has already been allocated to other filling sites, to CST5 or its vicinity. This allows the filling service in CST5 to continue. Then, the equipment unit 12 completes the process.

[0103] The preferred embodiments of the present invention have been described above, but the above embodiments have the following features.

[0104] The application server 2 (application system) utilizes multiple MST4s (mobile hydrogen stations). The application server 2 includes: a receiving unit 10, which accepts filling requests specifying at least the filling time and location; a planning unit 11, which generates allocation plan information for the multiple MST4s based on the filling requests received by the receiving unit 10; and an allocation unit 12, which performs allocation processing for the multiple MST4s based on the allocation plan information. If no two or more MST4s are scheduled to be allocated at the filling time specified in the filling request, the receiving unit 10 rejects the filling request. If a fully allocated or scheduled-to-be-allocated MST4 fails, the allocation unit 12 performs allocation processing by allocating the MST4s that were not scheduled to be allocated at the filling time assigned to the failed MST4. Based on the above structure, an application technique capable of handling MST4 failures is implemented.

[0105] If a configured MST4 malfunctions and multiple MST4s are in standby mode, the configuration unit 12 performs the configuration process by configuring the MST4 closest to the filling location assigned to the malfunctioning MST4 among the multiple standby MST4s. Based on this structure, configuration costs can be reduced.

[0106] If a pre-equipped MST4 malfunctions and multiple MST4s are in standby mode, the equipping unit 12 will replace the malfunctioning MST4 and equip the MST4 with the highest fill capacity among the standby MST4s. Based on this structure, the MST4 with the highest fill capacity will be equipped at the filling location assigned to the malfunctioning MST4.

[0107] If a fully equipped MST4 malfunctions and there are no MST4s in standby mode, the equipment unit 12 performs equipment processing by time-sharing the equipment of MST4s already equipped to other filling locations to the filling location assigned to the malfunctioning MST4. Based on this structure, filling services in the aforementioned filling locations can continue without canceling already received filling requests.

[0108] In the event that a pre-assigned MST4 fails, and multiple MST4s are not assigned a pre-assigned MST4 during their assigned fill-up time, the planning unit 11 updates the allocation plan information by assigning the MST4 closest to the fill-up location of the pre-assigned MST4 among the multiple unassigned MST4s. Based on this structure, allocation costs can be reduced.

[0109] If a scheduled MST4 fails and no scheduled MST4 is provided during the filling time assigned to the failed MST4, the planning unit 11 updates the allocation plan information by time-sharing the allocation of MST4s scheduled to be provided to other filling locations during that filling time to the filling location assigned to the failed MST4. Based on this structure, filling services at the aforementioned filling locations can continue without canceling already received filling requests.

[0110] The hydrogen supply system 1 also utilizes CST5 (a stationary hydrogen station). In the event of a CST5 malfunction, the equipment unit 12 performs equipment installation by placing a standby MST4 at or near the CST5. Based on this structure, refilling services at the CST5 can continue.

[0111] The method for using multiple MST4s includes: an acceptance step (S100) of accepting a filling request that specifies at least a filling time and a filling location; a planning step (S120) of generating configuration plan information for multiple MST4s based on the filling request received by the acceptance unit 10; and a configuration step (S200) of performing configuration processing for the multiple MST4s based on the configuration plan information. In the acceptance step, if there are not two or more MST4s without a scheduled configuration at the filling time specified in the filling request, the filling request is rejected (S130). In the configuration step, if a configured or scheduled configuration MST4 fails, the configuration process is performed by configuring one of the multiple MST4s that was not scheduled to be configured during the filling time assigned to the failed MST4 (S150), replacing the failed MST4. Based on the above method, an application technique capable of handling MST4 failures is implemented.

[0112] Furthermore, in the absence of a standby MST4, the equipment unit 12 can also temporarily connect to a mobile hydrogen station from a hydrogen supply system located in a nearby administrative district.

[0113] In addition, the amount of space that a single MST4 can fill is limited. Therefore, if multiple fill requests exist at the same time and in the same fill location, and the amount of space requested by a new fill request exceeds the remaining fillable space of the MST4, the fill request can be rejected.

[0114] In the examples above, various types of non-transitory computer-readable media can be used to store programs and supply them to a computer. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (e.g., floppy disks, magnetic tapes, hard disks) and optical-magnetic recording media (e.g., optical discs). Other examples include CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memories (e.g., mask ROMs). Further examples include PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (random access memory). Alternatively, programs can also be supplied to a computer via various types of transient computer-readable media. Examples of transient computer-readable media include electrical signals, optical signals, and electromagnetic waves. Transient computer-readable media can supply programs to a computer via wired communication paths such as wires and optical fibers, or via wireless communication paths.
