[0028] An information processing device according to one embodiment of the present disclosure comprises: an acquisition unit, which acquires status data representing the status of a monitored device from a communication device of a monitored device serving as a storage element or a power supply-associated device or a communication device of a system including a plurality of monitored devices through communication; a storage processing unit, which establishes a correspondence between the acquired status data and identification data of the monitored device or the system and stores the data in a storage medium; and a sending processing unit, which sends display information in response to a request from the outside or sends display information as an event, wherein the display information distinguishes the status data stored in the storage medium from the communication status with the communication device for each monitored device or each system and displays them together.

[0029] The power storage element may be a lithium-ion battery or a lead-acid battery, but is not limited thereto and may be other secondary batteries, primary batteries, or capacitors.

[0030] The storage element may be a storage cell or a storage module formed by connecting a plurality of storage cells in series and / or in parallel. The storage element may be a storage unit (hereinafter also referred to as a "bank") formed by connecting a plurality of storage modules in series. The storage element may also be a storage unit (hereinafter also referred to as a "domain") formed by connecting a plurality of storage modules or groups in parallel.

[0031] The power supply-related device may be any one of a power conditioner, an uninterruptible power supply (UPS), a rectifier, a DC power supply, a charger for an electric vehicle, or a charger / discharger.

[0032] The information processing device may monitor a system including a plurality of storage elements or power supply-related devices, or a storage system including only storage elements. The information processing device may monitor only power supply-related devices, or a system including a plurality of storage elements and power supply-related devices.

[0033] In the above structure, based on the status obtained from the communication equipment of the monitored object device or the communication equipment of the system, information can be obtained to distinguish whether it is the status detected in the monitored object device or the monitored object device included in the system, or the communication status detected between the monitored object device and the information processing device.

[0034] According to the above structure, even when a plurality of systems or monitoring target devices are monitored, a maintenance worker who can visually confirm the screen displayed based on the display information can recognize the location of the status of each system or each monitoring target device and understand the status of each system or each monitoring target device.

[0035] In the information processing device, the acquisition unit acquires the measurement data of each of the monitored object devices, and the information processing device has an analysis processing unit. The analysis processing unit analyzes whether the monitored object device or system has any abnormality or signs of abnormality based on the acquired measurement data through an algorithm for each of the monitored object devices or each system. The sending processing unit can also send display information, and the display information displays the analysis results of the analysis processing unit separately from the status data and the communication status for each of the monitored object devices or each system.

[0036] In the above structure, the information processing device estimates the status not only based on the status data obtained through communication from the communication device of the monitored device, but also by analyzing the measurement data accumulated in the monitored device. The information processing device can display the status detected in the monitored device, the communication status, and the analysis result separately.

[0037] According to the above configuration, the maintenance operator can distinguish the status obtained in the monitored device from the analysis result of the estimated abnormality and the sign of the abnormality to understand the status.

[0038] The display information may be information for distinguishing and displaying the analysis result for which monitoring target device is included in the monitoring target device or system.

[0039] According to the above structure, the maintenance operator can understand in which object included in the system or the monitored object the state is detected for each system or each monitored object device. For example, although the abnormality is not detected in the management device of the lithium-ion battery itself, it is possible to visually distinguish in advance whether the sign of abnormality is detected based on the analysis result, so that the maintenance operator can determine the maintenance activities that should be performed and can expect efficient maintenance activities.

[0040] The display information may be information for displaying the state of the monitoring target device or system by distinguishing which part included in the monitoring target device or system has detected the state.

[0041] In the above structure, the maintenance operator can understand, for each system or each monitored device, which storage element or monitored device contained in the system or monitored device has detected the state or the communication state. It is possible to visually distinguish in advance whether the abnormality is detected in the lead-acid battery or the lithium-ion battery, so that the maintenance operator can determine the maintenance activities to be performed, and can expect efficient maintenance activities.

[0042] The display information may be information for displaying a graphic visually showing the status data and the communication status together in a corresponding portion of the list of the monitored devices or systems.

[0043] In the above configuration, since the status and communication status are displayed in a graphical form in correspondence with each monitoring target device or each system, the maintenance operator can easily grasp them visually.

[0044] The display information may include information for transferring, for each of the monitoring target devices or each system, a portion included in the monitoring target device or system or detailed information of the monitoring target device to a screen displayed according to a hierarchical structure of the monitoring target device or system.

[0045] In the above configuration, the display information for indicating which part the status is, includes information that can be transferred to a screen for displaying detailed information of the system or device to be monitored in a hierarchical manner. Thus, the maintenance operator can roughly distinguish the location and grasp the status of the system or device to be monitored, and can also grasp which part of the system or device to be monitored is in what state.

[0046] The information processing device comprises: an acquisition unit, which acquires status data representing the status of a monitored object device from a communication device of a monitored object device which is a storage element or a power supply-related device or a communication device of a system including a plurality of monitored object devices through communication; and a sending processing unit, which sends display information in response to a request from the outside or sends display information as an event, wherein the display information is used to distinguish and display the communication status between the information processing device and the communication device and the communication status between the communication device and the monitored object device for each of the monitored object devices or each system.

[0047] In the above structure, based on the status obtained from the communication equipment of the monitored object device or the communication equipment of the system, information can be obtained that can be displayed separately to indicate the communication status between the information processing device itself and the communication equipment, or the communication status between the communication equipment and the monitored object device.

[0048] The information processing system includes: a plurality of communication devices, which are mounted on or connected to a monitoring target device as a storage element or a power supply-related device or a system including a plurality of monitoring target devices; an information processing device capable of communication connection with the plurality of communication devices; and a client device having a display unit capable of communication connection with the information processing device. The information processing device sequentially acquires status data representing the status of the monitoring target devices from the plurality of communication devices; establishes a correspondence between the acquired status data and the identification data of the monitoring target device or system and stores the data in a storage medium; generates display information in response to a request from the outside or generates display information as an event, wherein the display information distinguishes the status data stored in the storage medium and the communication status with the communication device for each monitoring target device or each system and displays them together; and sends the generated display information to the client device.

[0049] An information processing method, which sequentially acquires status data representing the status of a monitored device from a communication device of a monitored device serving as a storage element or a power supply-related device or a communication device of a system including a plurality of monitored devices through communication; establishes a correspondence between the acquired status data and identification data of the monitored device or the system and stores the data in a storage medium; sends display information in response to an external request or as an event, wherein the display information distinguishes the status data stored in the storage medium from the communication status with the communication device for each monitored device or each system and displays the data together.

[0050] A computer program enables a computer that is communicatively connected to a communication device of a monitored object device that is a storage element or a power supply-associated device, or a communication device of a system that includes a plurality of monitored object devices, to perform the following processing: sequentially acquiring status data representing the status of the monitored object device from the communication device of the monitored object device or the communication device of the system; establishing a correspondence between the acquired status data and identification data of the monitored object device or the system and storing the data in a storage medium; and sending display information in response to an external request or as an event, wherein the display information distinguishes the status data stored in the storage medium from the communication status with the communication device for each monitored object device or each system and displays them together.

[0051] The present invention will be described in detail with reference to the accompanying drawings showing the embodiments.

[0052] (First Embodiment)

[0053] Figure 1 1 is a diagram showing an overview of a remote monitoring system 100. The remote monitoring system 100 can remotely access information related to power storage elements and power supply-related devices included in a large-scale solar power generation system S, a thermal power generation system F, and a wind power generation system W. It is also possible to remotely monitor a rectifier (DC power supply device) D provided in an uninterruptible power supply device (UPS) U, a stabilized power supply system, and the like.

[0054] A power conditioner (PCS: Power Conditioning System) P and a power storage system 101 are arranged in parallel in a large solar power generation system S, a thermal power generation system F, and a wind power generation system W. The power storage system 101 can also be configured to have a plurality of containers C containing power storage module groups L arranged in parallel. The power storage module group L and the power conditioner P of the power storage system 101 can also be arranged in a building (power storage room). The power storage module group L includes a plurality of power storage elements. The power storage element is preferably a secondary battery such as a lead-acid battery and a lithium-ion battery, or a rechargeable element such as a capacitor. A part of the power storage element may also be a non-rechargeable primary battery.

[0055] In the remote monitoring system 100, a communication device 1 (see FIG. 1 ) is mounted or connected to each of the power storage system 101 or power supply-related devices (P, U, D and a management device M described later) in the systems S, F, and W to be monitored. Figure 2 The remote monitoring system 100 includes a communication device 1, a server device 2 (information processing device: a term in the claims) for collecting information from the communication device 1, a client device 3 for browsing the collected information, and a network N as a communication medium between the devices.

[0056] The communication device 1 may be a terminal device (metering monitor) that communicates with a battery management unit (BMU: Battery Management Unit) of a storage element and receives information of the storage element, or may be a controller corresponding to ECHONET / ECHONETLite (registered trademark). The communication device 1 may be an independent device, or may be a network card type device that can be mounted on a power conditioner P or a storage module group L. The communication device 1 is, for example, an independent communication device that is configured to collect status data from a slave that measures the internal resistance, voltage, current, temperature, etc. of a lead-acid battery, i.e., a storage element, through wireless communication. The communication device 1 is, for example, a network card type device that is assembled into a storage device formed by connecting lithium-ion batteries in series and is connected to a control substrate of the storage device.

[0057] The communication device 1 is provided for each group including a plurality of storage modules in order to obtain information on the storage module group L in the storage system 101. There are a plurality of power conditioners P connected for serial communication, and the communication device 1 is connected to the control unit of any representative power conditioner P.

[0058] The server device 2 includes a Web server function, and in response to an access from the client device 3 , presents information obtained from the communication device 1 mounted on or connected to each device to be monitored.

[0059] The network N includes a public communication network N1, which is the so-called Internet, and a carrier network N2 that implements wireless communication based on a prescribed mobile communication standard. The public communication network N1 includes a general optical line, and the network N includes a dedicated line to which the server device 2 is connected. The network N may also include a network that supports ECHONET / ECHONETLite. The carrier network N2 includes a base station BS, and when the client device 3 is a communication terminal, it can communicate with the server device 2 from the base station BS via the network N. When the access point AP is connected to the public communication network N1 and the client device 3 is a communication terminal, information can be sent and received between the server device 2 from the access point AP via the network N. The communication device 1 mounted / connected to the system S, F, W, and the independent power supply-related device P, U, D can communicate with the server device 2 or the client device 3 from the network within the system through the public communication network N1 and via the network N.

[0060] The power storage module group L of the power storage system 101 has a hierarchical structure. The communication device 1 that transmits the information of the power storage elements to the server device 2 acquires the information of the power storage elements included in the power storage module group L from the management device M provided in the power storage module group L. Figure 2The diagram shows an example of a hierarchical structure of a power storage module group L and a connection method of a communication device 1. The power storage module group L is composed of a hierarchical structure of a group of a plurality of power storage cells (also referred to as a cell) connected in series and a domain of a plurality of groups connected in parallel.

[0061] exist Figure 2 In the example, management devices M are provided one by one for each group numbered (#) 1 to N and the domains connecting the groups in parallel. The management device M of each group communicates with each control substrate (CMU: Cell Monitoring Unit: battery cell monitoring unit) with a communication function built into the storage module through serial communication to obtain the measurement data (current, voltage, temperature, internal resistance, etc.) of the storage cells inside the storage module. The management device M of the group performs management processing such as detection of abnormalities in the communication status between the communication module and the control substrate and detection of voltage abnormalities of each cell. The management device M of the group sends the measurement data obtained from the storage modules of each group to the management device M provided in the domain. The management device M of the domain summarizes information such as measurement data obtained from the management device M of the group belonging to the domain and detected abnormalities. In Figure 2 In the example of , the communication device 1 is connected to the domain management device M. Alternatively, the communication device 1 may be connected to the domain management device M and the group management device M, respectively.

[0062] In the remote monitoring system 100, the server device 2 uses the communication device 1 installed / connected to each device to collect information such as the state of SOC, SOH (State Of Health) in the power storage system 101, abnormalities detected in the power supply-related device itself, and abnormalities detected in the communication device 1. Based on the collected state, in addition to the detected abnormality, the server device 2 can derive the state of the monitored device included in the power storage system 101 based on the accumulated measurement data using an algorithm suitable for each system and device, and present the state.

[0063] Figure 3 1 is a block diagram showing the internal structure of the devices included in the remote monitoring system 100. Figure 3 As shown, the communication device 1 includes a control unit 10, a storage unit 11, a first communication unit 12, and a second communication unit 13. The control unit 10 is a processor using a CPU (Central Processing Unit), which uses a built-in memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory) to control each component to execute processing.

[0064] The storage unit 11 uses a non-volatile memory such as a flash memory. The storage unit 11 stores a device program 1P read and executed by the control unit 10. The device program 1P includes a communication program based on SSH (Secure Shell), SNMP (Simple Network Management Protocol), etc. The storage unit 11 stores information such as information collected through the processing of the control unit 10, event logs, etc. The information stored in the storage unit 11 can also be read through a communication interface such as a USB terminal exposed to the housing of the communication device 1. The device program 1P stored in the storage unit 11 can also be a program that the control unit 10 reads the device program 4P stored in the recording medium 4 and copies it to the storage unit 11.

[0065] The first communication unit 12 is a communication interface for realizing communication with the monitored device connected to the communication device 1. The first communication unit 12 uses, for example, a serial communication interface based on RS232C or RS485. For example, a power supply-related device such as a power conditioner P includes a control unit having a serial communication function based on RS485, and the first communication unit 12 communicates with the control unit. In the case where the control substrates of the power storage module group L are connected via a CAN (Controller Area Network) bus and communication between the control substrates is realized via CAN communication, the first communication unit 12 is a communication interface based on the CAN protocol. The first communication unit 12 may also be a communication interface corresponding to the standard of ECHONET / ECHONETLite.

[0066] The second communication unit 13 is an interface for realizing communication via the network N, and uses, for example, a communication interface such as Ethernet (registered trademark) or a wireless communication antenna. The control unit 10 can be connected to the server device 2 for communication via the second communication unit 13. The second communication unit 13 may also be a communication interface corresponding to the ECHONET / ECHONETLite standard.

[0067] In the communication device 1 configured as above, the control unit 10 acquires the measurement data on the power storage element obtained in the device equipped with / connected to the communication device 1 via the first communication unit 12. When the control unit 10 detects an abnormality or a warning state of the device, an abnormality or a warning state of the power storage element, etc. in the device equipped with / connected to the communication device 1, the control unit 10 acquires the status data. The control unit 10 may also function as an SNMP agent by reading and executing an SNMP program, and transmit the status data by responding to an information request from the server device 2 when an abnormality or a warning state is detected in the measurement data.

[0068] The server device 2 uses a server computer and includes a control unit 20, a storage unit 21, and a communication unit 22. In the first embodiment, the server device 2 is described as a single server computer, but processing may be distributed among a plurality of server computers.

[0069] The control unit 20 is a processor using a CPU or a GPU (Graphics Processing Unit), and uses a built-in memory such as a ROM and RAM to control each component and execute processing. The control unit 20 executes communication and information processing based on a server program 21P stored in the storage unit 21. The server program 21P includes a Web server program, and the control unit 20 functions as a Web server that provides Web pages to the client device 3. Based on the server program 21P, the control unit 20 collects information from the communication device 1 as an SNMP server.

[0070] The storage unit 21 uses a nonvolatile memory such as a hard disk or a flash memory. The server program 21P and the data processing program 22P are stored in the storage unit 21. The server program 21P and the data processing program 22P stored in the storage unit 21 may be programs that the control unit 20 reads the server program 51P and the data processing program 52P stored in the recording medium 5 and copies to the storage unit 21.

[0071] The storage unit 21 stores the measurement data of the power conditioner P and the storage module group L of the power storage system 101 as the monitoring object collected by the processing of the control unit 20. When other power supply related devices (rectifier D, uninterruptible power supply device U, etc.) are included in the monitoring object, their measurement data are also stored. The measurement data is associated with the identification information (number, mark) for identifying the system or device. The measurement data of the storage module group L is stored according to the domain, group, module or single body and hierarchical structure.

[0072] A plurality of images for displaying the state of the storage module group L or the power supply-related devices P, U, and D of the monitored object are stored in the storage unit 21. The plurality of images are associated with the identification information for identifying the storage module group L or the power supply-related devices P, U, and D of the monitored object and stored in the storage unit 21. The plurality of images include images representing the storage module group L or the power supply-related devices P, U, and D. These images are, for example, icons, marks, or illustrations that can identify the type of the storage module group L, that is, lead storage battery or lithium ion battery. The plurality of images are icons, marks, or illustrations that can identify the type of the power supply-related devices P, U, and D, that is, power conditioner P, uninterruptible power supply device U, or rectifier D. The plurality of images include images representing the configuration of the storage module group L or the power supply-related devices P, U, and D. These images are photos such as aerial photos and satellite photos, 2D maps, design drawings, CAD drawings, or illustrations. These images can be stored by uploading from the client device 3. In a photograph, map, design drawing, drawing or illustration, the position or range of the storage module group L or power supply-related devices P, U, D of the monitored object is stored for each image. The information indicating the position or range is, for example, coordinate information corresponding to the image. In the case where the image is an aerial photograph, a satellite photograph or a map, it may also be information indicating latitude and longitude information and a relative position. The multiple images stored in the storage unit 21 may also include illustrations, icons, animations and other images used to indicate the status (abnormal / normal / caution) of the storage module group L or the power supply-related devices P, U, D. In addition to images for displaying the status, the storage unit 21 may also store design data such as style sheets and scripts for visually outputting the status of the storage system 101 and the power supply-related devices P, U, D in the Web library.

[0073] The communication unit 22 is a device that realizes communication connection and transmission and reception of information via the network N. Specifically, the communication unit 22 is a network card corresponding to the network N.

[0074] The client device 3 is a computer used by an operator such as a manager or maintenance operator of the power storage system 101 of the power generation system S, F, W. The client device 3 may be a desktop or laptop personal computer, or a so-called smart phone or tablet communication terminal. The client device 3 includes a control unit 30, a storage unit 31, a communication unit 32, a display unit 33, and an operation unit 34.

[0075] The control unit 30 is a processor using a CPU. The control unit 30 causes the display unit 33 to display a Web page provided by the server device 2 based on the client program 3P stored in the storage unit 31. The client program 3P is incorporated into the Web page provided by the Web server function of the server device 2, includes a script and a Web browser program temporarily stored in the client device 3, and is a program for displaying a Web-based screen based on the actions in the server device 2.

[0076] The storage unit 31 uses a nonvolatile memory such as a hard disk or a flash memory. Various programs including the client program 3P are stored in the storage unit 31. The client program 3P may be a program that the control unit 30 reads the client program 6P stored in the recording medium 6 and copies to the storage unit 31.

[0077] The communication unit 32 uses a network card for wired communication and is connected to the base station BS (see Figure 1 ) for mobile communication or corresponding to a wireless communication device connected to an access point AP (refer to Figure 1 The control unit 30 can communicate with the server device 2 or the communication device 1 installed or connected to each device through the network N through the communication unit 32 or the communication connection or the transmission and reception of information.

[0078] The display unit 33 uses a display such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 33 displays an image of a web page provided by the server device 2 by processing by the client program 3P of the control unit 30. The display unit 33 may be a display with a built-in touch panel or a display without a built-in touch panel.

[0079] The operation unit 34 is a user interface such as a keyboard, a pointing device, or a voice input unit that can input and output with the control unit 30. The operation unit 34 may also use a touch panel of the display unit 33 or a physical button provided on the housing. The operation unit 34 notifies the control unit 30 of the user's operation information.

[0080] In the remote monitoring system 100 configured in this way, the server device 2 periodically acquires the status data and measurement data of the system or device to be monitored from the communication device 1 based on the data processing program 22P, and stores them in the storage unit 21 (acquisition unit, storage processing unit). The system or device to be monitored is composed of any one or more of the storage system 101 including the storage module group L, the power conditioner P, the uninterruptible power supply device U and the rectifier D. The server device 2 stores the structural data representing the hierarchical structure of the storage module group L (domain, group, module, single unit) and / or the power supply related devices P, U, D in the system to be monitored. The structural data representing the hierarchical structure can be set in advance for each system, or can be derived from the data sent by the communication device 1 in which the data are associated with each other in a parent-child relationship. In the case where the power supply related devices P, U, D used alone are the monitoring target devices, the server device 2 stores the structural data indicating that the monitoring target devices are used alone. The server device 2 can generate screen information visually representing the status in each hierarchy based on the hierarchical structure of the power storage module group L (domain, group, module, single unit) and / or power supply-related devices P, U, D in the monitored system, and provide prompts in response to requests from the client device 3.

[0081] Figure 4 This is a flowchart showing an example of processing in the communication device 1. The communication device 1 mounted on or connected to the management device M and other power-related devices P, U, and D repeatedly executes the following processing steps periodically or in response to a request from the server device 2.

[0082] The control unit 10 of the communication device 1 determines whether it is possible to communicate with the mounted / connected monitoring target device through the first communication unit 12 (step S101). When it is determined that communication is possible (S101: Yes), the control unit 10 obtains the data sent from the monitoring target device (step S102). The control unit 10 establishes a correspondence with the identification data for identifying which storage element the data is and stores it in the storage unit 11 (step S103), and the process proceeds to step S106.

[0083] In step S102, the control unit 10 acquires measurement data obtained from the monitored device. When an abnormality or a cautionary state is detected in the monitored device, the control unit 10 also acquires status data indicating the abnormality or the cautionary state. The status data includes date and time information when the abnormal state is detected.

[0084] When it is determined in step S101 that communication is impossible (S101: No), the control unit 10 detects a communication anomaly between the monitored device and the communication device 1 (step S104), establishes a correspondence between the log of the communication anomaly with the monitored device and the identification data and date and time information for identifying the monitored device, and stores the log (step S105), and proceeds to the next step S106.

[0085] Before the processing of step S105, the control unit 10 may also determine the abnormality or caution state of the monitored device through the processing of the communication device 1 in the device program 1P based on the acquired measurement data and / or status data. In this case, the control unit 10 establishes a corresponding relationship between the status data indicating the abnormality or caution state determined by the communication device 1 and the identification data and date and time information of the monitored device and stores them.

[0086] The control unit 10 determines whether it is possible to connect to the network N through the second communication unit 13 (step S106). If it is determined that the connection is possible (S106: Yes), the control unit 10 sends the stored measurement data and the log or status data of the communication abnormality if any to the server device 2 from the second communication unit 13 (step S107), and ends the one-time processing.

[0087] If it is determined that the connection cannot be made (S106: No), the control unit 10 stores a log of the abnormal communication with the server device 2 (step S108), and ends the one-time processing. The log of the abnormal communication stored in step S108 is sent in the log of the abnormal communication (a record associated with the date and time information) step S107 at the timing of the next abnormal communication recovery together with the measurement data from the monitored device stored during the period when the communication cannot be made.

[0088] In addition, Figure 4 In the processing steps shown in the flowchart, the processing of steps S101 to S104 and the processing of steps S106 to S108 can also be executed independently.

[0089] The communication device 1 can distinguish and store the result (status data) of determining whether the monitored device (power storage module group L) is in an abnormal or warning state, the communication abnormality between the monitored device and the communication device 1, and the communication abnormality between the communication device 1 and the server device 2, and send them to the server device 2.

[0090] Figure 51 is a flowchart showing an example of the steps of data processing by the server device 2. The server device 2 periodically performs the following processing on each communication device 1 using the information of the system or device of each monitoring target periodically acquired and stored from the communication device 1. The server device 2 may also perform the following processing each time a transmission from the communication device 1 is detected.

[0091] The control unit 20 of the server device 2 determines whether it is possible to communicate with the target communication device 1 among the plurality of communication devices 1 included in the system or device to be monitored (step S201). In step S201, when processing is performed regularly, the control unit 20 determines whether a communication connection can be established using the address of the selected communication device 1 among the plurality of communication devices 1. When a transmission from the communication device 1 is detected, the control unit 20 determines whether a transmission from the communication device 1 has been received more than a specified number of times within a specified period in the past.

[0092] When the control unit 20 determines that it is possible to communicate with the communication device 1 as the target (S201: Yes), it receives data including the measurement data sent from the communication device 1 and stores it in the storage unit 21 (step S202), and ends the processing. The processing of step S202 corresponds to the "acquisition unit" and the "storage processing unit". The identification data of the communication device 1 as the transmission source, the identification data of the monitoring target device of the communication device 1, the date and time information, etc. are associated with the measurement data acquired in step S202. In step S202, the control unit 20 stores the received data as these identification data.

[0093] When the control unit 20 determines that it is impossible to communicate with the target communication device 1 (S201: No), it stores the communication anomaly log in correspondence with the identification data and date and time information of the target communication device 1 (step S203), and ends the process. Steps S202 and S203 correspond to the "storage processing unit".

[0094] according to Figure 5 In the processing steps shown, the communication device 1 of the transmission source is identified, and the measurement data, the status data indicating the abnormality or the caution state, the log of the communication abnormality that can identify the abnormal part, etc. are sequentially stored in the storage unit 21 of the server device 2. The control unit 20 stores the structural data for determining which system or monitoring target device each communication device 1 belongs to. Therefore, for each system or each monitoring target device, it is possible to determine in which of the one or more communication devices 1 included in the system or the monitoring target device the abnormality or the caution state is detected.

[0095] Figure 6This is a flowchart showing an example of information processing steps in the server device 2. The server device 2 uses Figure 5 The processing steps shown are executed in response to a request or event from the client device 3 based on the information of each system or each monitoring target device acquired and stored by each communication device 1. The event may be a periodic detection or a detection of a state change of each system or monitoring target device such as an abnormality.

[0096] The control unit 20 selects one identification system or identification data of a monitoring target device (step S301).

[0097] The control unit 20 determines whether it is possible to communicate with the monitoring target device identified by the selected identification data or the communication device 1 mounted / connected to the monitoring target device included in the system (step S302). When the control unit 20 determines that communication is possible (S302: Yes), the communication normality in the first communication path is associated with the identification data selected in step S301 and temporarily stored (step S303), and the processing proceeds to step S305. The first communication path indicates the communication path between the server device 2 and the communication device 1.

[0098] When the control unit 20 determines that communication is impossible (S302: No), the control unit 20 associates the communication abnormality in the first communication path with the identification data selected in step S301 and temporarily stores the associated information (step S304), and then advances the process to step S305.

[0099] The control unit 20 determines whether there is an abnormality or a warning state detected by the monitoring target device or the monitoring target device included in the system identified by the selected identification data (step S305). When the control unit 20 receives status data indicating an abnormality or a warning state detected by the monitoring target device via the communication device 1, the control unit 20 sequentially stores the status data in the storage unit 21. In step S305, the control unit 20 determines whether the status data corresponding to the date and time information within a specified period from the current time is stored.

[0100] When the control unit 20 determines that there is an abnormality or a caution state detected by the monitored device (S305: Yes), it establishes a correspondence between the abnormality or the caution state of the monitored device and the identification data selected in step S301 and temporarily stores it (step S306), and the processing enters step S308.

[0101] When it is determined that there is no abnormality or caution state detected by the monitored device (S305: No), the normal state of the monitored device is associated with the identification data selected in step S301 and temporarily stored (step S307), and the processing proceeds to step S308.

[0102] The control unit 20 determines whether or not there is a communication abnormality between the communication device 1 included in the system or monitoring target device identified by the selected identification data and the monitoring target device (step S308).

[0103] In step S308 , when a log (status data) of an abnormality detected by the process of the communication device 1 itself or an abnormality in the caution state is stored, the control unit 20 may determine that an abnormality exists with respect to the abnormality.

[0104] When the control unit 20 determines that the communication device 1 has detected a communication anomaly with the monitored device (S308: Yes), the communication anomaly in the second communication path is associated with the identification data selected in step S301 and temporarily stored (step S309), and the process proceeds to step S311. The second communication path represents the communication path between the monitored device and the communication device 1.

[0105] When the control unit 20 determines that there is no communication abnormality between the communication device 1 and the monitored device (S308: No), it establishes a correspondence between the normal communication in the second communication path and the identification data selected in step S301 and temporarily stores them (step S310), and the processing enters step S311.

[0106] The control unit 20 performs analysis processing based on the measurement data accumulated in the storage unit 21 and stores the analysis processing (step S311) for each type of the power storage element or power supply-related device included in the system or monitoring target device identified by the selected identification data. The analysis processing in step S311 corresponds to the "analysis processing unit".

[0107] In step S311, the control unit 20 derives the SOC of each cell in each layer using an algorithm for lithium-ion batteries, for example, when the power storage system 101 included in the system includes power storage elements that are lithium-ion batteries. Figure 2In the case of the power storage system 101 having the structure shown, the hierarchy is, for example, domain, group, and module, and the control unit 20 derives not only the SOC in units of single cells, but also the SOC in units of domains, groups, and modules. The control unit 20 derives the remaining service life based on the accumulated measurement data. For example, when the power storage system 101 included in the system includes a storage element as a lead-acid battery, the control unit 20 uses an algorithm for the lead-acid battery to derive the SOC and the remaining service life for the entire power storage system 101 or each divisible unit. The control unit 20 can also refer to the data such as the purchase date and the maintenance inspection date from the customer information database, and judge whether it can be used safely before the expiration of the guarantee period based on the relationship between the remaining service life of the storage element and the guarantee period. In addition, when the system includes a power conditioner P or the monitoring target device is a power conditioner P, the control unit 20 judges the consumption degree of the deteriorated component or the presence or absence of abnormal signs. The control unit 20 may determine the service life (consumption degree) of the uninterruptible power supply device U and the rectifier D included in the system or the uninterruptible power supply device U and the rectifier D as the monitoring target device, or the presence or absence of a sign of abnormality.

[0108] The control unit 20 determines whether all the identification data have been selected (step S312). If it is determined that all the identification data have not been selected (S312: No), the control unit 20 returns the process to step S301 to select the next identification data.

[0109] When it is determined that all the identification data are selected (S312: Yes), the process ends.

[0110] according to Figure 5 and Figure 6 In the processing steps shown, the control unit 20 of the server device 2 maintains information on communication anomalies, abnormal states, or attention states and analysis results updated regularly or in response to events for each system or device to be monitored. The client device 3 appropriately requests the information updated by the server device 2, and displays it at a glance on the display unit 33, which can be presented in a manner that the operator can easily visually confirm.

[0111] Figure 7 and Figure 8 2 is a flowchart showing an example of a process procedure for presenting information from the server device 2 to the client device 3. When the client device 3 receives a login request from the Web browser, the server device 2 starts the following process.

[0112] The control unit 20 as a Web server receives a login request and login data from the client device 3 (step S401). In step S401, the control unit 20 receives a key such as an ID and a password for identifying an operator such as a maintenance operator or an administrator who uses the client device 3. The control unit 20 may receive biometric information instead of a password.

[0113] The control unit 20 extracts identification data of a system or monitoring target device with access rights associated with an ID identifying the operator based on the received login data (step S402). If authentication of the received login data fails in step S402, subsequent processing is omitted and ends.

[0114] The control unit 20 refers to the communication anomaly, detected anomaly or caution state, and analysis result stored in the system or monitoring target device identified by the extracted identification data (step S403).

[0115] The control unit 20 generates data of a web page including a list of extracted systems or monitored devices based on design data such as a style sheet stored in the storage unit 21 (step S404). In step S404, the control unit 20 generates data of a web page so that the communication anomalies, detected anomalies or attention states, and icons visually representing the analysis results of each system or each monitored device referenced in step S403 are associated with the list and displayed. In detail, the control unit 20 generates information of a screen that represents the presence or absence of anomalies or attention detected in the monitored device, the presence or absence of communication anomalies in the second communication path, the presence or absence of communication anomalies in the first communication path, and the results of the analysis process with icons corresponding to the states for each system or each monitored device. The screen also includes link information to the screen, which displays detailed information that can confirm the state of each hierarchical structure of the storage element contained in the system or monitored device, and the presence or absence of anomalies or attention states in each structural unit in the power supply-related device (refer to Fig.10 ).

[0116] The control unit 20 transmits the information of the generated web page to the client device 3 that is the source of the login request (step S405).

[0117] After the client device 3 transmits the login data via the communication unit 32 (step S501), it receives the data of the web page including the list of systems or monitoring target devices having access rights (step S502). The control unit 30 displays the web page on the display unit 33 (step S503).

[0118] As described above, in the web page displayed in step S503, icons visually indicating communication anomalies, detected anomalies or caution states, and analysis results for each system or each monitored device are displayed in a manner corresponding to the list of monitored systems or monitored devices. Thus, operators such as maintenance workers or managers can visually confirm which parts of each system or each monitored device are abnormal or in a caution state and which parts are normal.

[0119] The displayed web page includes link information for displaying detailed information on each system or each monitoring target device. The control unit 30 receives selection of link information on the web page (step S504), and sends a request for data of the web page indicated by the selected link information to the server device 2 (step S505).

[0120] The control unit 20 of the server device 2 receives a request for data specifying link information (step S406), and based on the link information, sends data for a detailed web page for displaying the selected system or device to the client device 3 (step S407). The processing of step S407 corresponds to the "sending processing unit". The data of the web page sent in step S407 has a structure that can be transferred between hierarchical structures according to the hierarchical structure of the selected system or monitored device. Each web page includes an image representing the configuration of the selected system or device such as the position in the building, the position in the container C, the position in the battery panel, and graphic data such as illustrations, icons, and animations used to represent the status of each hierarchy. These graphics can be selected by the operating unit 34. When selected, the control unit 30 transfers to a web page of another hierarchy based on the link information corresponding to the graphic through the function of the web browser (refer to Fig.12 , 14). The control unit 30 displays the numerical value of the measurement data of the device or the structural part on the screen through the script.

[0121] The control unit 30 of the client device 3 receives the data of the web page (step S506), and displays the web page showing the details on the display unit 33 based on the received data (step S507). Then, while the display of the web page in step S507 is maintained, based on the script (automatic update) included in the data of the web page, the control unit 30 receives the state data or detected state data in the hierarchy of the object derived based on the measurement data of the selected system or monitoring target device from the server device 2, and updates and displays it in the web page. Fig. 9 2P is a diagram for explaining the function of the automatic monitoring unit 2P. Fig. 9As shown, the automatic monitor unit 2P functions based on the cooperation of the Web server program and design data included in the server program 21P and the Web browser program included in the client program 3P, thereby realizing the status display through automatic updating. The automatic monitor unit 2P can also realize sending data to the client device 3 through https communication at intervals of 10 seconds or 15 seconds, for example.

[0122] The control unit 30 determines whether link information to another level is selected in the detailed web page representing the target system or monitoring target device (step S508). If it is determined that the link information is selected in a manner such as a graphic corresponding to the link information (S508: Yes), a request for displaying data of the detailed web page of the selected level is sent to the server device 2 based on the corresponding link information (step S509). If it is determined that it is not selected (S508: No), the control unit 30 advances the process to step S512.

[0123] The control unit 20 of the server device 2 receives the request for data specifying the link information (step S408), and transmits data of a detailed web page for displaying the selected layer to the client device 3 based on the link information (step S409). The control unit 20 transmits the web page data each time it receives the request for data specifying the link information (S408) until the display of the web page is terminated in the client device 3 (S409).

[0124] The control unit 30 of the client device 3 receives data of a detailed web page indicating the selected level (step S510). The control unit 30 causes the display unit 33 to display a detailed web page indicating the selected level (step S511). In step S511, Fig. 9 As shown, while the display of the Web page is maintained, the control unit 30 receives the status of the layer as the object derived based on the measurement data of the selected layer from the server device 2 based on the script (automatic update) contained in the data of the Web page of the selected layer, and updates the display within the Web page.

[0125] The control unit 30 determines whether an operation to end the display of the Web page of the target system or the monitoring target device has been accepted (step S512). If it is determined that the operation has not been accepted (S512: No), the process returns to step S508. In step S512, if the Web browser is closed, or a logout is selected, or a selection is made to move to the Web page displayed in step S502, the control unit 30 may determine that the end operation has been accepted.

[0126] When it is determined that the end operation has been accepted (S512: YES), the control unit 30 ends the information presentation process.

[0127] exist Figure 7 and Figure 8 In the processing steps shown, the automatic updating script is included in the web page for displaying the information of the system or the monitored device, and the status of each layer is automatically updated (also called the automatic monitoring function). Figure 6 The steps shown in the figure update the contents of the web page periodically or by the status of each layer and the results of the analysis process derived in response to an event. Alternatively, the status update may be configured such that each time the operator operates the operation unit 34 of the client device 3 to select another layer or the top layer, an update request is sent from the client device 3 to the server device 2. In this case, in response to the event of receiving the update request, the server device 2 may also update the target system according to the following steps: Figure 6 The steps shown perform the export and analysis process of the status of each level and send the exported data periodically.

[0128] A specific example of a Web page presented by the server device 2 will be described with reference to the drawings. Figure 10 to Figure 14 This is a diagram showing a specific example of a Web page presented by the server device 2. Fig.10 A web screen (a screen displayed on the display unit 33 of the client device 3) 330 showing a list of systems or monitoring target devices to which the logged-in operator has been given authority is shown. Fig.10 For example, Figure 1 The name of the large solar power generation system S shown is "XY City Large Solar Power System", the name of the wind power generation system W is "WZ Power Plant System", and other systems are displayed in list form.

[0129] exist Fig.10 In the web screen 330 of FIG. 1 , for each system and monitored device, icons 331 indicating the status are included in the items of “monitored device”, “communication”, and “analysis result”. The icon 331 in the item of “monitored device” indicates whether an abnormality or a warning state is detected in the monitored device in the system and the independent monitored device. The icon 331 in the item of “communication” indicates whether an abnormality is detected in the communication between the server device 2 and the communication device 1 included in the system and the monitored device in the first communication path in the server device 2. The icon 331 in the item of “analysis result” indicates the result of the analysis processing performed by the server device 2 based on the measurement data for the system and the monitored device.

[0130] exist Fig.10 In the example, the icons 331 indicate the three states of "abnormal", "caution" and "normal (no problem)". For example, in the "XY City Large Solar Energy System", the icons 331 of the "Monitored Device", "Communication" and "Analysis Result" items are all "normal". That is, in the "XY City Large Solar Energy System", no abnormality or caution is detected in the monitored device, the communication device 1, or the server device 2. In the "WZ Power Plant System", the icon 331 of the "Monitored Device" item indicates "abnormal", the icon 331 of the "Communication" item indicates "normal", and the icon 331 of the "Analysis Result" item indicates "caution". That is, it is determined that in the "WZ Power Plant System", an abnormality is detected in the monitored device, the communication between the server device 2 and the communication device 1 is normal, and the server device 2 should pay attention to the monitored device. In the "K Railway System", the icons 331 of the "Monitored Device" and "Analysis Result" items indicate "normal", and the icon 331 of the "Communication" item indicates "abnormal".

[0131] The operator can distinguish and recognize, for each system or each monitored device, whether the abnormal part is an abnormality detected in the monitored device or a communication abnormality occurs, by using the Web screen 330. The operator can distinguish the faults occurring on site by where the faults are caused by using the Web screen 330. The Web screen 330 allows the operator to recognize the sign of abnormality detection through the analysis result of the server device 2 even if an abnormality or a warning state is not detected in the monitored device and the communication device 1 at the time of confirming the screen. The server device 2 performs analysis suitable for the type of storage element or power supply related device included in the system or monitored device. The operator can confirm the results of abnormality detection performed on the system or monitored device by different methods by using the Web screen 330 without performing a lot of operations. In addition, regarding the communication abnormality, it can be distinguished whether the abnormal part is a communication abnormality between the monitored device and the communication device 1 or a communication abnormality between the communication device 1 and the server device 2.

[0132] exist Fig.10 In the web screen 330 of the client device 3, a "MAP" icon 332 is displayed in correspondence with each system or each monitoring target device. The "MAP" icon 332 is associated with link information that links to a screen showing details of the target system or monitoring target device. When the link information is selected, the control unit 30 of the client device 3 specifies the link information and requests the server device 2 to display a web page showing details of the system or monitoring target device.

[0133] Fig.11An example of a screen 333 is shown in which a "MAP" icon 332 of a system or a monitoring target device is selected. Fig.11 Screen 333 shows Fig.10 The “WZ Power Plant System” in the list of systems or monitoring target devices shown is selected by operation of the operation unit 34 of the client device 3. The screen 333 includes a layout image K (a line diagram or a photograph such as a CAD drawing) showing the arrangement of a plurality of power storage module groups L. Fig.11 The screen 333 shows the structure and status of the system in the top layer of the hierarchical structure of the "WZ power plant system". Fig.11 The screen 333 includes a layout image K of the entire eight power storage rooms constituting the "WZ power plant system". Fig.11 The layout image K of FIG. 330 represents the battery panel accommodating the three groups constituting the domain with a small rectangle. The screen 333 includes the layout image K and a graphic object 334 visually representing the state of the "WZ power plant system".

[0134] The graphic object 334 is a graphic that indicates the state of the power storage element arranged in the portion superimposed on the system layout image K. The color or display method of the graphic object 334 may be different depending on the state (abnormal / caution / normal) of the entire system on which the graphic object 334 is superimposed.

[0135] Screen 333 includes a display item column 335. Fig.11 In the example shown, the display item bar 335 includes four icons, namely "All", "Voltage", "Current" and "Temperature". The screen 333 includes an independent information bar 338 for independently switching the units for displaying the status in each level. The independent information bar 338 includes buttons for selecting units such as voltage, current, temperature, resistance, and capacity. When a unit is selected in the independent information bar 338, the buttons in the independent information bar 338 and the display item bar 335 indicate that any one of "voltage", "current" and "temperature" is selected. When a unit is selected in the independent information bar 338, the graphic object 334 displays the presence or absence of an abnormality / caution status in the unit and the degree of the abnormality for the measured data. Fig.11 When the "voltage" button is selected in the independent information column 338, the screen 333 indicates the status of the "voltage" item, that is, whether the voltage is abnormal, by the color and display method of the rectangular graphic object 334 superimposed on each monitoring target device (storage element).

[0136] The "all" item of the display item column 335 can be selected. When the "all" item is selected, the screen 333 shows the status of the items corresponding to "voltage", "current" and "temperature" by the color and display method of the graphic object 334. By operating the independent information column 338 and the display item column 335, the screen 333 uses the same layout image K and displays the status based on different measurement data.

[0137] In addition, the graphic object 336 displays information in groups using the independent information bar 338, and displays information in groups using text or the like. Fig.11 The value of the selected unit among the voltage, current, and temperature of the battery panel represented by the small rectangle on the layout image K. When the operator selects "voltage" using the independent information column 338, when the operator selects a small rectangle on the screen 333 using the operation unit 34, the total voltage or average voltage of the battery panel of the selected small rectangle is displayed in the small rectangle or its periphery.

[0138] exist Fig.11 The buttons or icons of "All", "Voltage", "Current" and "Temperature" in the display item column 335 in the display item column 335 each display an icon 351 indicating the status determined from the perspective of each item. In addition to voltage, current and temperature, "All" also includes, for example, the communication status. The "Communication Status" in the screen 333 for displaying the details of the system or the monitored device indicates the communication status in the second communication path, that is, the communication status between the monitored device and the communication device 1, which can be compared with Fig.10 That is, since the communication between the communication device 1 and the server device 2 is normal, the real-time detailed information can be displayed on the screen 333, but if there is a communication anomaly between the communication device 1 and each monitored device, it will be displayed separately on the screen 333.

[0139] Icon 351 indicates three states: "Abnormal", "Caution" and "Normal (no problem)". Fig.11 In the example of FIG. 1 , an icon 351 indicating an “abnormal” state is displayed on the “all” button, and an icon 351 indicating a “caution” state is displayed on the “voltage” button. An icon 351 indicating a “normal” state is displayed on the “current” and “temperature” buttons.

[0140] Fig.11 The screen 333 includes a graphic object 336 showing the SOC of the storage element included in the system. The graphic object 336 can also use a plurality of modules, a plurality of groups, or a plurality of domains as one evaluation unit to show the SOC of the evaluation unit (the total SOC of a plurality of modules or groups). Fig.11In the screen 333 of FIG. 3 , the SOC value of the evaluation unit is displayed along the graphic object 336. The SOC value is calculated based on, for example, the SOC value calculated as a group in which a plurality of modules are connected. The SOC value is, for example, a value calculated as an average value.

[0141] pass Fig.11 For a large-scale ESS including a huge number of modules, the layout image K and the graphic objects 334 and 336 can be used to enable the operator who confirms the screen 333 to grasp the overall situation.

[0142] When a module, group or domain in layout image K is selected (i.e., a selection object in layout image K, which may also be the same as the evaluation unit of SOC), the screen information describing screen 333 includes a script that will transition to a state where a lower level is displayed.

[0143] The screen 333 may include a hierarchy menu 337 that displays the hierarchy of the power storage system 101. Fig.11 In FIG. 3 , the hierarchy menu 337 indicates the hierarchy of “entire” corresponding to the uppermost hierarchy. The hierarchy in the hierarchy menu 337 includes link information for returning to the screen 333 of the upper hierarchy every time the hierarchy shifts from the uppermost hierarchy to the lower hierarchy.

[0144] Fig.12 33 is a diagram showing an example of a screen 333 showing a status of transition to another level. Fig.12 is Fig.11 When a portion corresponding to any storage room (for example, the portion corresponding to the third storage room from the left of block A) is selected on the layout image K shown, the automatic monitor unit 2P displays the image on the web browser of the client device 3. Fig.12 In FIG. 3 , the screen 333 includes a reduced image of the overall layout image K of the upper layer before the transfer on the left side of the screen, and includes the layout image K of the selected power storage room on the right side.

[0156] (Second Embodiment)

[0157] In the second embodiment, the server device 2 presents a screen that allows identification of which device or component included in the system or the monitoring target device the status of the monitoring target system or the monitoring target device is.

[0158] The configuration of the remote monitoring system 100 of the second embodiment is the same as that of the first embodiment except for the details of the processing in the server device 2 shown below. In the configuration of the remote monitoring system 100 of the second embodiment, the same reference numerals are given to the configurations common to the remote monitoring system 100 of the first embodiment, and detailed descriptions thereof are omitted.

[0159] Fig.15 FIG. 2 is a flowchart showing an example of an information processing procedure in the server device 2 according to the second embodiment. Figure 6 The common steps in the processing steps shown are denoted by the same step numbers and detailed descriptions are omitted.

[0160] In the second embodiment, when the control unit 20 of the server device 2 determines that an abnormality or a caution state is detected in the monitored device (S305: Yes), the abnormality or the caution state in the monitored device is associated with the identification data selected in step S301 for each type of the monitored device and is temporarily stored (step S326). When an abnormality or a caution state is detected, the identification data of the monitored device as the monitored object is associated with the status data sent from the communication device 1 (refer to S202). Therefore, in step S326, the control unit 20 uses the identification data of the monitored device and the structure data of the system or the monitored device as the monitored object stored in the server device 2 to determine whether the monitored device for which the status data is detected is a storage element, a power conditioner P, an uninterruptible power supply device U, or a rectifier D.

[0161] After executing the processing (S309, S310) based on the result of determining whether there is a communication anomaly with the monitored device in step S308, the control unit 20 uses an algorithm for each type to perform analysis processing based on the measurement data accumulated in the storage unit 21, and stores the analysis results separately for each type (step S321).

[0162] Through the processing steps of the second embodiment, the control unit 20 of the server device 2 stores information about communication anomalies, abnormal states, or attention states, and analysis results updated periodically or in response to events for each system or each monitored device, respectively, by type of monitored device. The client device 3 appropriately requests the information updated by the server device 2, and displays it at a glance on the display unit 33, so that the operator can be prompted to visually confirm where and what kind of anomalies have occurred in the initial Web screen 330.

[0163] Fig.16 This is a diagram showing a specific example of a Web page presented by the server device 2. Fig.16 A web screen 330 showing a list of systems or monitoring target devices to which the logged-in operator has been given authority is shown. In the second embodiment, the web screen 330 displayed on the client device 3 includes icons 331 for indicating the status of each system and monitoring target device, respectively, in the items of "monitoring target device", "communication" and "analysis result". The icon 331 in the "monitoring target device" item distinguishes and indicates which monitoring target device in the monitoring target device and the system has detected an abnormality or a warning state. In the case where there is a component as a monitoring target device that should be distinguished as a separate monitoring target device, the icon 331 can be distinguished for each component. The icon 331 in the "analysis result" item displays the result of the analysis process performed by the server device 2 based on the measurement data for the system and the monitoring target device, distinguished from the monitoring target device as the target.

[0164] exist Fig.16 In the example, an icon 339 for identifying the type of monitoring target device or monitoring target device included in the monitoring target device or system, that is, a storage element, a power conditioner P, an uninterruptible power supply device U, a rectifier D, etc., is displayed in the "monitoring target device" and "analysis result" items of the list. Icons 331 indicating the three states of "abnormal", "caution" and "normal (no problem)" are added and displayed next to the icon 339 indicating the type of the monitoring target device.

[0165] exist Fig.16For example, the "XY City Large Solar Energy System" includes a power storage system 101 and a power conditioner P composed of lithium-ion batteries, and the icons 331 of the "Monitored Device", "Communication" and "Analysis Result" items are all "Normal". The "WZ Power Plant System" includes a power storage system 101 and a power conditioner P having both lithium-ion batteries and lead-acid batteries, and shows that a warning state is detected in the power storage system 101 of the lead-acid battery. The web screen 330 indicates that the server device 2 determines that the lead-acid battery included in the "WZ Power Plant System" should be paid attention to. In the "K Railway System", the power storage system 101 of the lead-acid battery and the rectifier D are included, and the icons 331 of the "Monitored Device" and "Analysis Result" items are all indicated as "Normal" for any device, and the icon 331 of the "Communication" item is indicated as "Abnormal".

[0166] Thus, using the web screen 330 of the second embodiment, the operator can identify in detail whether an abnormality is detected in the monitored device itself or a communication abnormality occurs for each system or each monitored device in a partially distinguished manner. The operator can distinguish the fault occurring on site by using the web screen 330 according to which device the fault is.

[0167] The embodiments disclosed above are intended to be illustrative in all aspects and not restrictive. The scope of the present invention is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are included.
