The event may be the arrival of periodic detection, or the detection of a change in the state of a system or device such as the occurrence of an abnormality.

The control unit 20 selects one piece of identification data that identifies a system or device to be monitored (step S101).

The control unit 20 determines whether the system or monitored device identified by the selected identification data includes a power storage element (step S102). If it is determined that a power storage element is included (S102: YES), it is determined whether the system or monitored device identified by the selected identification data includes a hierarchically structured power storage element (step S103).

If it is determined that the system or the monitored device includes power storage elements in a hierarchical structure (S103: YES), the control unit 20 derives the state of charge (SOC) for each hierarchy (Step S104).

In step S104, for example, when the power storage element is a lithium ion battery, the control unit 20 derives the SOC of the cell for each layer using an algorithm for lithium ion batteries. In the case of the power storage system 101 having the structure shown in FIG. 2, the hierarchy is, for example, domains, banks, and modules, and the control unit 20 controls not only the SOC of each cell, but also the SOC of each domain, bank, and module. Derive. Alternatively, when the power storage element is a lead-acid battery, the control unit 20 derives the SOC for the entire power storage system 101 or for each divisible unit using an algorithm for lead-acid batteries.

The control unit 20 associates the SOC derived for each hierarchy with the currently selected identification data and the names (identification data) that identify each of the hierarchically structured power storage element groups (power storage module group L), that is, domains, banks, etc. It is temporarily stored (step S105).

If it is determined in step S103 that the system or the monitored device does not include a hierarchically structured power storage element (S103: NO), the control unit 20 skips the processing in step S104 and step S105 and continues the processing in step S103. Proceed to S106.

In step S106, the control unit 20 derives the SOC of the entire power storage element included in the system or monitored device of the selected identification data (step S106). The control unit 20 temporarily stores the SOC derived in step S106 in association with the currently selected identification data (step S107), and advances the process to step S108.

If it is determined in step S102 that the power storage element is not included (S102: NO), the control unit 20 skips the processes of steps S104 to S107 and advances the process to step S108.

The control unit 20 identifies the presence or absence of an abnormality in the system or monitored device identified by the selected identification data (step S108), and temporarily stores the identified result in association with the identification data of the selected system or device. (step S109).

The control unit 20 determines whether all identification data for identifying the system or device to be monitored has been selected (step S110). If it is determined that all have been selected (S110: YES), the control unit 20 ends one process. If it is determined in step S110 that not all have been selected (S110: NO), the control unit 20 returns the process to step S101.

Through the process shown in the flowchart of FIG. 4, the status (SOC and/or presence or absence of abnormality) of each system and monitored device at the timing of a request from the client device 3 or the timing of an event occurrence (state change, etc.) ) is temporarily stored in the storage unit 21. The stored state information is updated each time there is a request from the client device 3 or each time an event occurs (such as a change in state).

Creation of screen information and information presentation in the server device 2 will be explained. 5 and 6 are flowcharts showing an example of a processing procedure for presenting information from the server device 2 to the client device 3. FIG.

When the client device 3 receives a login request from the maintenance worker using the client program 3P, the client device 3 transmits login data to the server device 2 (step S301). When the login data is accepted, the following processing is started.

The control unit 20, as a web server, receives a login request and login data from the client device 3 (step S201). In step S201, the control unit 20 receives a key such as an ID and password for identifying a maintenance worker who uses the client device 3. The control unit 20 may receive biometric information instead of the password.

Based on the received login data, the control unit 20 extracts identification data of the system or monitored device that has access authority associated with the ID that identifies the maintenance worker (step S202). In step S202, if the authentication of the received login data fails, subsequent processing is omitted and the processing ends.

The control unit 20 refers to the state data held by the process shown in FIG. 4 for the system or monitored device identified by the extracted identification data (step S203).

The control unit 20 creates Web page data including the list of systems or monitored devices extracted in step S202, based on design data such as a style sheet stored in the storage unit 21 (step S204). The web page created in step S204 also includes link information to a screen that displays the status of each hierarchical structure of power storage elements included in the system or monitored device, and detailed information on each component of the power supply-related device. (See Figure 8)

The control unit 20 transmits the created web page information to the client device 3 that has made the login request (step S205).

After transmitting login data through the communication unit 32 (S301), the client device 3 receives data of a web page including a list of systems or monitored devices that the maintenance worker who operates has access authority (step S302). ). The control unit 30 displays the web page on the display unit 33 (step S303).

As described above, a list of systems or devices to be monitored is displayed on the Web page displayed in step S303. The list includes link information for displaying detailed information about each system or monitored device. The control unit 30 accepts the selection of link information on the web page (step S304), and transmits a request for data of the web page indicated by the selected link information to the server device 2 (step S305).

The control unit 20 of the server device 2 receives a request for data of a web page specifying link information (step S206), and creates a web page for displaying details of the selected system or monitored device based on the link information. data is transmitted to the client device 3 (step S207). It has a configuration that allows transition between hierarchies according to the data of the web page transmitted in step S207, the hierarchical structure of the selected system or the monitored device. Each web page includes an image indicating the location of the selected system or monitored device in the building, in the container C, in the battery board, etc., and an icon indicating the orientation of the image. The Web page includes graphic data such as illustrations, icons, and animations for expressing the status of each hierarchy. These graphics may be selectable on the operation unit 34. When selected, the control unit 30 uses the function of the web browser to cause a transition to a web page in another hierarchy based on the link information associated with the graphic (reference). The control unit 30 displays numerical values of measurement data for the device or component on the screen using a script.

The control unit 30 of the client device 3 receives the data of the web page (step S306), and causes the display unit 33 to display the web page showing details based on the received data (step S307). Thereafter, while the display of the web page is maintained in step S307, the control unit 30 performs the following based on the measured data of the selected system or monitored device based on the script (automatic update) included in the data of the web page. , data on the state of the target hierarchy derived by the process shown in FIG. 4 is received from the server device 2, and updated and displayed within the Web page. FIG. 7 is a diagram illustrating the functions of the automatic monitor section 2P. As shown in FIG. 7, the status display is realized by automatically updating the function of the automatic monitor unit 2P based on the behavior 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. do. The automatic monitor unit 2P may realize data transmission to the client device 3 by https communication, for example, at 10 second intervals or 15 second intervals.

The control unit 30 determines whether link information to another hierarchy has been selected on the web page showing details of the selected system or monitored device (step S308). If it is determined that the link information has been selected, such as by selecting a graphic with which the link information is associated (S308: YES), details of the selected hierarchy are displayed based on the associated link information. A request for Web page data is sent to the server device 2 (step S309).

The control unit 20 of the server device 2 receives the request for data specifying the link information (step S208), and based on the link information, sends the data of the web page for displaying the details of the selected hierarchy to the client device 3. Transmit (step S209). The control unit 20 transmits the data of the web page to the client device 3 every time it receives a request for data specifying link information (S208) until an operation to end the display of the web page is performed on the client device 3 (S208). S209).

The control unit 30 of the client device 3 receives data of a web page showing details of the selected hierarchy (step S310). The control unit 30 causes the display unit 33 to display a web page showing details of the selected hierarchy (step S311). Also in step S311, as shown in FIG. 7, while the display of the web page is maintained, the control unit 30 performs the selection based on the script (automatic update) included in the data of the web page of the selected hierarchy. The state of the target hierarchy derived based on the measurement data of the determined hierarchy is received from the server device 2 and updated and displayed on the web page.

The control unit 30 determines whether or not the operation to end the display of the web page of the target system or the monitored device has been accepted (step S312), and if it is determined that the operation has not been accepted (S312: NO), the process proceeds to step S312. Return to S308. The control unit 30 may determine that the termination operation has been accepted if the web browser is terminated, logout is selected, or transition to the web page displayed in step S302 is selected in step S312. .

If it is determined that the termination operation has been accepted (S312: YES), the control unit 30 terminates the information presentation process.

In the processing steps shown in FIGS. 5 and 6, the Web page for displaying information about the system or monitored device includes an automatic update script, and the status in each hierarchy is automatically updated ( (also referred to as automatic monitoring function). Each time the web page is automatically updated, the content of the web page is updated by the server device 2 in accordance with the procedure shown in FIG. 4, either periodically or in response to an event, based on the state of each layer to be derived and the results of the analysis process. . Alternatively, the status update may be configured such that an update request is sent from the client device 3 to the server device 2 each time the operator operates the operation unit 34 of the client device 3 to select another layer or the highest layer. You can also use it as In this case, in response to the event that an update request has been received, the server device 2 may perform the derivation of the state of each layer and the analysis process for the target system according to the procedure shown in FIG. Data derived periodically may be transmitted.
