[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following drawings, the same components are denoted by the same reference numerals.

[0013] 1 , a distributed power management system 11 having an information processing device 10 according to an embodiment of the present disclosure is configured to include at least one regional system 14 including at least one distributed power supply apparatus 12 and a first terminal device 13, a second terminal device 15, and the information processing device 10. The information processing device 10 may communicate with the distributed power supply apparatus 12, the first terminal device 13, and the second terminal device 15 via a network 16.

[0014] A regional system 14 is installed, for example, at each electricity consumer facility. Load devices within the regional system 14 may be supplied with power from a distributed power supply device 12 included in the regional system 14. The distributed power supply device 12 may be, for example, a fuel cell device, a storage battery device, a solar power generation device, or the like. The regional system 14 may be provided with a single type of distributed power supply device 12, or may be provided with multiple different types of distributed power supply devices 12.

[0015] The distributed power supply system 12 may be provided with a plurality of sensors for detecting the operating state. The plurality of sensors may be, for example, a voltage sensor for the power output by the distributed power supply system 12, a current sensor, a temperature sensor, etc. No Se In a configuration in which the distributed power supply apparatus 12 is a fuel cell apparatus, the sensors may include flow meters for the supplied gas, air, and water, a temperature sensor for the reformer, and a conductivity sensor for the reformed water. The distributed power supply apparatus 12 may transmit, or in other words, provide, the values ​​detected by the multiple sensors as operating data to the information processing apparatus 10.

[0016] The first terminal device 13 may be intended for use by a user of a consumer facility. The first terminal device 13 may be, for example, a dedicated remote controller for the distributed power supply 12, or a general-purpose mobile terminal such as a tablet or smartphone. The first terminal device 13 may have a notification unit that notifies information using a display, a speaker, or the like. The first terminal device 13 can notify the operating status of at least one distributed power supply 12 belonging to the same regional system 14 via the notification unit.

[0017] As described below, the first terminal device 13 receives, or in other words, acquires, the first information as a signal from the information processing device 10 via the network 16. The first terminal device 13 may notify the acquired first information via a notification unit. The first terminal device 13 may have at least one input interface capable of detecting input from a user. When the first information includes an answer request notification described below, the first terminal device 13 may detect an answer using the input interface. The first terminal device 13 may transmit, or in other words, provide the detected answer as a signal to the information processing device 10.

[0018] The second terminal device 15 may be assumed to be used by a maintenance and management company of the distributed power supply device 12. Therefore, the second terminal device 15 is different from the first terminal device 13. The second terminal device 15 is, for example, a general-purpose terminal device such as a personal computer, a tablet, or a smartphone.

[0019] As described below, the second terminal device 15 receives, or in other words, acquires, the second information as a signal from the information processing device 10 via the network 16. Furthermore, the second terminal device 15 may receive, or in other words, acquire, predictive information, information indicating that immediate maintenance of the distributed power supply apparatus 12 is necessary, and information indicating that immediate maintenance is not necessary, as signals from the information processing device 10 via the network 16. The second terminal device 15 may have a notification unit that notifies information using a display, a speaker, or the like. The second terminal device 15 may notify the acquired second information, predictive information, information indicating that immediate maintenance of the distributed power supply apparatus 12 is necessary, and information indicating that immediate maintenance is not necessary via the notification unit.

[0020] 2, the information processing device 10 includes a communication unit 17 and a control unit 18. The information processing device 10 may further include a storage unit 19.

[0021] The communication unit 17 includes a communication module that communicates with the distributed power supply apparatus 12, the first terminal device 13, and the second terminal device 15 via the network 16. The communication unit 17 receives, in other words, acquires, operating data from the distributed power supply apparatus 12.

[0022] The communication unit 17 transmits, or in other words, assigns, as a signal, first information (described later) to the first terminal device 13 in the same regional system 14 as the distributed power supply device 12 to which the operating data has been assigned. The communication unit 17 transmits, or in other words, assigns as a signal, second information (described later) to the second terminal device 15. The communication unit 17 may transmit, or in other words, assign, as a signal, predictive information (described later) to the second terminal device 15. The communication unit 17 may transmit, or in other words, assign, as a signal, information indicating that urgent maintenance (described later) is required to the second terminal device 15. The communication unit 17 may transmit, or in other words, assign, as a signal, information indicating that urgent maintenance (described later) is not required to the second terminal device 15.

[0023] The storage unit 19 includes any one of a semiconductor memory, a magnetic memory, and an optical memory. Examples of the semiconductor memory include a random access memory (RAM) and a read-only memory (ROM). Examples of the RAM include a static random access memory (SRAM) and a dynamic random access memory (DRAM). Examples of the ROM include an electrically erasable programmable read-only memory (EEPROM). The storage unit 19 may function as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 19 stores data used in the operation of the information processing device 10 and data obtained by the operation of the information processing device 10. For example, the storage unit 19 stores system programs, application programs, embedded software, and the like. For example, the storage unit 19 stores operating data acquired from the distributed power supply apparatus 12 in chronological order.

[0024] The control unit 18 is configured to include at least one processor, at least one dedicated circuit, or a combination of these. The processor is a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for specific processing. The dedicated circuit may be, for example, an FPGA (Field-Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or the like.

[0025] The control unit 18 may store the operation data acquired by the communication unit 17 in the storage unit 19 in chronological order for each distributed power supply device 12, in other words, together with time information.

[0026] The control unit 18 can detect signs of failure of the distributed power supply apparatus 12 based on the operating data acquired from the distributed power supply apparatus 12. The operating data used to detect signs of failure may be operating data at at least one point in time. The operating data at one point in time is not limited to instantaneous operating data and may include a time range, for example, representative data in a range of seconds, minutes, hours, days, months, or years. The representative data may be a representative value in the time range, for example, an instantaneous value, an average value, a median value, etc. at a predetermined point in time in the time range. The operating data used to detect signs of failure may be operating data at multiple points in time, and may include operating data from the most recent point in time.

[0027] The control unit 18 may detect the failure sign using a variety of methods.

[0028] The control unit 18 creates an operation model trained by machine learning using operation data acquired during a normal period, and detects signs of failure by inputting newly acquired operation data into the operation model. The normal period is, for example, a predetermined period from the initial startup of multiple distributed power supply devices 12 of the same type to the period during which an initial defect occurs.

[0029] Furthermore, the control unit 18 may, for example, use a failure model that has been trained on the failure signs detected by the above-mentioned operating model and operating data at the time of actual failure to estimate the parts that are predicted to fail in the distributed power supply device 12, the type of failure, and the time when the failure will occur.

[0030] Alternatively, the control unit 18 may detect a sign of failure based on, for example, whether the acquired operating data is within a range of normal data. The normal data may be collected, for example, from operating data collected within a predetermined period after the initial startup of multiple distributed power supply units 12 of the same type and after the period during which an initial defect occurs has elapsed. Furthermore, if the acquired operating data indicates an abnormal state outside the range of normal data, the control unit 18 may estimate, based on the operating data, a part of the distributed power supply unit 12 that is predicted to fail, the type of failure, and the timing of the failure.

[0031] When estimating a component that is predicted to fail, the control unit 18 may determine whether the failure is minor or major depending on the component. A minor failure is, for example, a failure of an auxiliary device of a fuel cell device in a configuration in which the distributed power supply apparatus 12 is a fuel cell device, and refers to a failure that allows operation as long as it does not last for a long period of time. A component determined to be a minor failure is, for example, an auxiliary device in a configuration in which the distributed power supply apparatus 12 is a fuel cell device. A major failure is, for example, a failure of a cell stack or reformer of a fuel cell device in a configuration in which the distributed power supply apparatus 12 is a fuel cell device, and refers to a failure that may cause further failure of other devices or a failure in which damage progresses rapidly due to operation. A component determined to be a major failure is, for example, a cell stack in a configuration in which the distributed power supply apparatus 12 is a fuel cell device.

[0032] The failure sign may include a variety of information. For example, the failure sign may include at least one of the following: an abnormal state in the operating data; a predicted component in the distributed power supply 12 that is predicted to fail; the type of failure; and a prediction of when the failure will occur. In other words, the failure sign may include the abnormal state in the operating data, without including information about the type of failure in the distributed power supply 12 or the component that is predicted to fail.

[0033] The control unit 18 can generate first information based on the failure symptoms. More specifically, the control unit 18 can generate the first information when, for example, the failure symptoms include the type of failure of the distributed power supply apparatus 12. The control unit 18 may include information related to the maintenance management of the distributed power supply apparatus 12 in the first information. The information related to the maintenance management may include, for example, information that the distributed power supply apparatus 12 requires maintenance, and information about the time and estimated cost required for the maintenance.

[0034] Furthermore, the control unit 18 may include either a reply request notice or a reply-free notice in the first information based on the type of failure.

[0035] More specifically, if the type of predicted failure is a minor failure, the control unit 18 may include a response request notice in the first information. The response request notice may be a notice requesting a response as to whether the user requests maintenance work by a maintenance management company of the distributed power supply 12. The response request notice may further include a proposed maintenance date.

[0036] Alternatively, if the type of predicted failure is a major failure, control unit 18 may include a no-reply notification in the first information. The no-reply notification may be a notification including information regarding the shutdown of distributed power supply 12. When control unit 18 includes a no-reply notification in the first information, control unit 18 may issue a command to distributed power supply 12 corresponding to the no-reply notification to shut down that distributed power supply 12.

[0037] When the control unit 18 generates the first information, it controls the communication unit 17 to provide the first information to the first terminal device 13 in the same regional system 14 as the distributed power supply device 12 corresponding to the first information.

[0038] The control unit 18 generates second information based on the failure sign. The second information is different from the first information. The control unit 18 may include at least one of the type of failure and information about a component of the distributed power supply 12 that is predicted to fail in the second information. The information about the component may be, for example, information about the specific component whose failure is predicted, a predicted lifespan, and whether the component needs to be replaced. Alternatively, if the failure sign does not include information about the type of failure of the distributed power supply 12 and the component whose failure is predicted, the control unit 18 may include the presence of a failure sign in the second information. The presence of a failure sign may be, for example, an abnormal state in the operating data or operating data that has been identified as being in an abnormal state. When the control unit 18 includes a no-reply notification in the first information, the control unit 18 may include, in the second information, information indicating that immediate maintenance of the distributed power supply 12 is required. The information indicating the need for immediate maintenance may be, for example, "Please inquire with the consumer about maintenance and inspection within x days."

[0039] The control unit 18 controls the communication unit 17 so as to provide the generated second information to the second terminal device 15.

[0040] The control unit 18 may control the communication unit 17 to provide first information including an answer request notice to the first terminal device 13 and, if no answer is received within a response period to the answer request notice, to provide information to the second terminal device 15 indicating that immediate maintenance is not required. The control unit 18 may control the communication unit 17 to provide first information including an answer request notice to the first terminal device 13 and, if an answer to the effect that maintenance is not required is received within a response period to the answer request notice, to provide information to the second terminal device 15 indicating that immediate maintenance is not required. The control unit 18 may control the communication unit 17 to provide first information including an answer request notice to the first terminal device 13 and, if an answer to the effect that maintenance is required is received within a response period to the answer request notice, to provide information about the consumer using the first terminal device 13 and information indicating that maintenance is required to the second terminal device 15.

[0041] Next, the failure sign detection process executed by the control unit 18 of the information processing device 10 in this embodiment will be described with reference to the flowchart in Fig. 3. The failure sign detection process is started periodically, periodically, or every time the information processing device 10 acquires operating data from any of the distributed power generation devices 12.

[0042] In step S100, the control unit 18 stores the most recently acquired driving data in the storage unit 19. After storage, the process proceeds to step S101.

[0043] In step S101, the control unit 18 reads out the operating data required for detecting a failure sign from the storage unit 19. After reading out, the process proceeds to step S102.

[0044] In step S102, the control unit 18 determines whether or not there is a malfunction sign based on the operating data read out in step S101. If there is no malfunction sign, the malfunction sign detection process ends. If there is a malfunction sign, the process proceeds to step S103.

[0045] In step S103, the control unit 18 determines whether the failure type is included in the failure symptom. If the failure type is included, the process proceeds to step S104. If the failure type is not included, the process proceeds to step S112.

[0046] In step S104, the control unit 18 determines whether the type of failure is a minor failure or a major failure. If it is a minor failure, the process proceeds to step S105. If it is a major failure, the process proceeds to step S106.

[0047] In step S105, the control unit 18 generates an answer request notice. After generation, the process proceeds to step S107. In step S106, the control unit 18 generates an answer no-need notice. After generation, the process proceeds to step S107.

[0048] In step S107, the control unit 18 generates first information including the reply request notice generated in step S105 or the no reply necessary notice generated in step S106. After generation, the process proceeds to step S108.

[0049] In step S108, the control unit 18 assigns the first information generated in step S107 to the first terminal device 13 in the same regional system 14 as the distributed power supply device 12 to which the operating data was assigned. After assignment, the process proceeds to step S109.

[0050] In step S109, the control unit 18 determines whether or not information about a part predicted to fail is included. If information about a part predicted to fail is included, the process proceeds to step S110. If information about a part predicted to fail is not included, the process proceeds to step S111.

[0051] In step S110, the control unit 18 generates information regarding the type of failure and the component that is predicted to fail. After generation, the process proceeds to step S113. In step S111, the control unit 18 generates information regarding the type of failure. After generation, the process proceeds to step S113. In step S112, the control unit 18 generates information regarding the presence of a failure symptom. After generation, the process proceeds to step S113.

[0052] In step S113, the control unit 18 generates second information so as to include the information on the type of failure and the part generated in step S110, the information on the type of failure generated in step S111, or the information on the presence of a failure symptom generated in step S112. After generation, the process proceeds to step S114.

[0053] In step S114, the control unit 18 provides the second information generated in step S113 to the second terminal device 15. After providing the second information, the failure sign detection process ends.

[0054] Next, the maintenance request management process executed by the control unit 18 of the information processing device 10 in this embodiment will be described with reference to the flowchart of Fig. 4. The maintenance request management process starts after the first information including the reply request notice is provided.

[0055] In step S200, the control unit 18 starts timing, after which the process proceeds to step S201.

[0056] In step S201, the control unit 18 determines whether or not a response has been received from the first terminal device 13. If a response has been received, the process proceeds to step S202. If a response has not been received, the process proceeds to step S204.

[0057] In step S202, it is determined whether the received response is a response requesting maintenance. If the response is a response requesting maintenance, the process proceeds to step S203. If the response is not a response requesting maintenance but a response indicating that maintenance is not required, the process proceeds to step S205.

[0058] In step S203, the control unit 18 provides information about the customer using the first terminal device 13 and information that maintenance is being requested to the second terminal device 15. After providing the information, the process proceeds to step S206.

[0059] In step S204, the control unit 18 determines whether the timing started in step S200 has elapsed to the response period. If not, the process returns to step S201. If yes, the process proceeds to step S205.

[0060] In step S205, the control unit 18 provides information that no immediate maintenance is required to the second terminal device 15. After providing this information, the process proceeds to step S206.

[0061] In step S206, the control unit 18 resets and stops the timekeeping that started in step S200, and after stopping, the maintenance request management process ends.

[0062] The information processing device 10 of this embodiment, configured as described above, includes a communication unit 17 that communicates with at least one regional system 14 and a second terminal device 15. The communication unit 17 detects a failure sign of the distributed power supply 12 based on the operational data of the distributed power supply 12 acquired by the communication unit 17, generates first information based on the failure sign, controls the communication unit 17 to provide the first information to a first terminal device 13 in the same regional system 14 as the distributed power supply 12, generates second information different from the first information based on the failure sign, and controls the communication unit 17 to provide the second information to the second terminal device 15. Even if a failure sign of the distributed power supply 12 can be identified, the information required based on the failure sign typically differs depending on the destination, such as a consumer or a maintenance management company. In this situation, the information processing device 10 configured as described above can provide information appropriate to the destination based on the failure sign.

[0063] Furthermore, in the information processing device 10 of this embodiment, the first information includes information related to the maintenance management of the distributed power supply 12, and the second information includes information related to a component of the distributed power supply 12 that is predicted to fail. A consumer desires information related to maintenance management, such as the possibility of a failure occurring, the time until the failure occurs, the time and cost required for maintenance, etc., but does not need information related to the component of the distributed power supply 12 that is predicted to fail, such as the location where the failure is predicted to occur, the type of failure, or the component that needs to be replaced. The opposite is true for a maintenance management company. In response to this assumption, the information processing device 10 allows the consumer to use the first terminal device 13 and the maintenance management company to use the second terminal device 15, thereby being able to provide information suitable for both parties.

[0064] Furthermore, when the failure symptoms do not include a failure of distributed power supply 12, information processing device 10 of this embodiment includes in the second information an indication of the presence of a failure symptom. With this configuration, when the failure symptoms do not include a failure of distributed power supply 12 and information related to the maintenance and management of distributed power supply 12 cannot be created, information processing device 10 can generate only the second information and provide it to second terminal device 15 without generating the first information. Therefore, information processing device 10 can contribute to the creation of medium- to long-term maintenance schedules for maintenance and management businesses, while stopping the provision of information that only causes anxiety to consumers.

[0065] Furthermore, when the failure symptom includes the type of failure of the distributed power supply 12, the information processing device 10 of this embodiment includes either a response request notice or a response not required notice in the first information based on the type of failure. With this configuration, the information processing device 10 can generate first information depending on whether the failure is one that allows for the consumer's decision. Therefore, the information processing device 10 can allow for the consumer's decision while improving the possibility of failure prevention through maintenance.

[0066] Furthermore, in information processing device 10 of this embodiment, the no-reply notification includes information regarding the shutdown of distributed power supply 12, and when the no-reply notification is included in the first information, information indicating the need for immediate maintenance of distributed power supply 12 is included in the second information. With this configuration, when it is expected that maintenance is highly urgent, information processing device 10 can notify the maintenance management company of the need for maintenance without waiting for a decision from the consumer.

[0067] Furthermore, if the information processing device 10 of this embodiment does not receive a response from the first terminal device 13 within the response period for the response request notice, it provides information to the second terminal device 15 that no immediate maintenance is required. With this configuration, the information processing device 10 can reduce the complexity of the response operation by the consumer by determining that no maintenance is required unless the consumer clearly expresses their intention.

[0068] The above has described an embodiment of the information processing device 10, but the embodiment of the present disclosure can also be implemented as a method or program for implementing the device, or as a storage medium on which a program is recorded (for example, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a CD-RW, a magnetic tape, a hard disk, or a memory card, etc.).

[0069] Furthermore, the implementation form of the program is not limited to application programs such as object code compiled by a compiler or program code executed by an interpreter, but may also be in the form of a program module incorporated into an operating system. Furthermore, the program may or may not be configured so that all processing is performed solely by the CPU on the control board. The program may also be configured so that part or all of it is executed by another processing unit mounted on an expansion board or expansion unit added to the board as needed.

[0070] The drawings illustrating the embodiments of the present disclosure are schematic, and the dimensional ratios and the like in the drawings do not necessarily correspond to the actual ones.

[0071] Although the embodiments of the present disclosure have been described based on the drawings and examples, it should be noted that those skilled in the art could make various modifications or alterations based on the present disclosure. Therefore, it should be noted that these modifications or alterations are included in the scope of the present disclosure. For example, the functions included in each component can be rearranged so as not to cause logical inconsistencies, and multiple components can be combined or divided into one.

[0072] All of the features described in this disclosure and / or all steps of all of the disclosed methods or processes may be combined in any combination except combinations in which these features are mutually exclusive. Furthermore, each feature described in this disclosure may be replaced by an alternative feature serving the same, equivalent, or similar purpose, unless expressly denied. Thus, unless expressly denied, each disclosed feature is only one example of a generic series of identical or equivalent features.

[0073] Furthermore, embodiments of the present disclosure are not limited to the specific configurations of any of the above-described embodiments, but rather extend to any novel feature or combination thereof described herein, or any novel method or process step or combination thereof described herein.

[0074] In this disclosure, descriptions such as "first" and "second" are identifiers for distinguishing the configuration. Configurations distinguished by descriptions such as "first" and "second" in this disclosure can exchange numbers in the configuration. For example, a first terminal device can exchange identifiers "first" and "second" with a second terminal device. The exchange of identifiers is performed simultaneously. The configurations remain distinguished even after the identifier exchange. Identifiers may be deleted. Configurations from which identifiers have been deleted are distinguished by symbols. The descriptions of identifiers such as "first" and "second" in this disclosure should not be used solely to interpret the order of the configurations or to justify the existence of identifiers with smaller numbers.
