The power management support device 140 manages power in the power management support system 100.
FIG. 4 is a block diagram schematically showing the configuration of power management support device 140 in the first embodiment.
The power management support device 140 includes a storage section 141, a communication section 142, and a processing section 150.

The storage unit 141 stores information and programs required for processing by the power management support device 140.

The communication unit 142 communicates with various devices connected to the network 101. For example, the communication unit 142 communicates with the terminal device 110, the production system 120, and the power meter 130.

The power consumption acquisition unit 151 acquires power consumption information indicating the power consumption of the production system 120 from the power meter 130 via the communication unit 142. The acquired power consumption information is stored in the storage unit 141 in association with the time when the power consumption information was acquired.

The plan management section 152 acquires production plan information indicating a production plan for producing products in the production system 120 from the production system 120 via the communication section 142 . The production plan information is given to the prediction section 154 and the plan editing screen generation section 157.

Here, the production plan indicates at least the time at which production equipment is to be operated for each product to be produced. Furthermore, when products are produced on multiple lines, the production plan may indicate the time at which production equipment is to be operated for each line. Furthermore, the production plan may include the operation details of the production equipment if the operation details of the production equipment affect the power consumption of the production equipment.

Furthermore, the plan management unit 152 can change the production plan in the production system 120 by sending changed production plan information indicating the changed production plan to the production system 120 via the communication unit 142. It is assumed that the end of the change is input by the user into the terminal device 110.

The user input acquisition unit 153 functions as an acquisition unit that acquires information indicating the content input to the terminal device 110 from the terminal device 110 via the communication unit 142.
For example, the user input acquisition unit 153 transmits information via the communication unit 142 when the production plan is changed in the terminal device 110 according to the authority of the user via an edit screen image or a change edit screen image, which will be described later. Then, changed part information indicating the changed content is obtained from the terminal device 110. The changed part information is given to the prediction unit 154 and the plan management unit 152.

The prediction unit 154 predicts the power to be consumed in the future by the production system 120 based on the production plan indicated by the production plan information from the plan management unit 152. Identify power consumption. The prediction unit 154 provides future power consumption information indicating the future power consumption to the power consumption screen generation unit 155.

Furthermore, when the prediction unit 154 receives the changed part information from the user input acquisition unit 153, it changes the production plan indicated by the production plan information from the plan management unit 152 with the contents indicated by the changed part information. Identify changing production plans. Then, the prediction unit 154 specifies the changed future power consumption, which is the power consumption in the changed production plan, by predicting the power to be consumed in the future by the production system 120 based on the changed production plan. The prediction unit 154 provides changed future power consumption information indicating the changed future power consumption to the power consumption screen generation unit 155.

The power consumption screen generation unit 155 generates a power consumption screen image representing future power consumption indicated by the future power consumption information from the prediction unit 154.
For example, the power consumption screen generation unit 155 displays the power consumption indicated by the power consumption information stored in the storage unit 141 and the future power consumption indicated by the future power consumption information from the prediction unit 154 in chronological order. Generate power screen images. Then, the power consumption screen generation unit 155 provides power consumption screen image information indicating the power consumption screen image to the screen transmission processing unit 158.

Further, the power consumption screen generation unit 155 generates a changed power consumption screen image representing the changed future power consumption indicated by the changed future power consumption information from the prediction unit 154.
For example, upon receiving the changed future power consumption information from the prediction unit 154, the power consumption screen generation unit 155 generates the power consumption indicated by the power consumption information stored in the storage unit 141 and the changed future power consumption information. A changed power consumption screen image is generated that represents the changed future power consumption in chronological order. Then, the power consumption screen generation unit 155 provides changed power consumption screen image information indicating the changed power consumption screen image to the screen transmission processing unit 158.

The user authority management unit 156 accepts a login from a user, and specifies the contents that the user can change in the production plan according to the authority that the user has to make changes related to electric power in the production system 120. do. For example, if the production system 120 is producing a first product and a second product, the administrator who manages the production of the first product may change the number of products produced, etc. of the second product. Therefore, the user has the authority to make changes related to the production of the first product. On the other hand, the administrator who manages the production of the second product is a user who has the authority to make changes regarding the production of the second product. In the first embodiment, the changeable contents are contents that can be changed in the production plan, so the contents specified here are also referred to as production plan changeable contents.

For example, the user authority management unit 156 acquires user authentication information from the terminal device 110 via the communication unit 142. Then, the user authority management unit 156 uses the registered authentication information stored in the storage unit 141 to authenticate the user authentication information. If the user authority management unit 156 fails in authentication, it sends a login error to the terminal device 110 that sent the user authentication information, and stops the subsequent processing. On the other hand, if the authentication is successful, the user authority management unit 156 identifies the user using the user name included in the successfully authenticated user authentication information according to the user authority information stored in the storage unit 141. The contents that can be changed by the user are determined according to the user's authority. Then, the user authority management unit 156 provides changeable content information indicating the specified content to the plan editing screen generation unit 157.

The plan editing screen generation unit 157 generates a plan editing screen image that allows the user to change production plan changeable contents, which are contents that can be changed in the production plan.
For example, the plan editing screen generation unit 157 generates changeable content indicated by the changeable content information from the user authority management unit 156 in the production plan indicated by the production plan information from the plan management unit 152. Generates a plan editing screen image that allows only editing. Then, the plan editing screen generation section 157 provides plan editing screen image information indicating the plan editing screen image to the screen transmission processing section 158. Note that in the production plan, if there is no content that can be changed by the user identified by the user name included in the user authentication information, the plan editing screen generation unit 157 will display a message indicating that there is no content that can be edited. It is sufficient to generate a plan editing screen image.

The screen transmission processing unit 158 sends the power consumption screen image or the changed power consumption screen image and the plan editing screen image to the terminal device 110 via the communication unit 142 so that the power consumption screen image or the changed power consumption screen image and the plan editing screen image can be displayed on one screen.
For example, the screen transmission processing unit 158 sends a power consumption screen image indicated by the power consumption screen image information from the power consumption screen generation unit 155 or a changed power consumption screen image indicated by the changed power consumption screen image information, and a plan editing screen. The plan editing screen image indicated by the image information is sent via the communication unit 142 to the terminal device 110 that sent the corresponding user authentication information. In other words, upon receiving the changed processed power screen image information, the screen transmission processing unit 158 sends the changed power consumption screen image to the terminal device 110 instead of the power consumption screen image.

Here, when the screen transmission processing unit 158 receives the power consumption screen image information from the power consumption screen generation unit 155, the screen transmission processing unit 158 combines the power consumption screen image indicated by the power consumption screen image information and the plan editing screen image information. An edit screen image including the shown plan edit screen image is generated. Then, the screen transmission processing section 158 causes the communication section 142 to transmit the editing screen image information indicating the editing screen image to the terminal device 110 that has sent the corresponding user authentication information.

In addition, when the screen transmission processing unit 158 receives the changed power consumption screen image information from the power consumption screen generation unit 155, the screen transmission processing unit 158 sends a changed power consumption screen image indicated by the changed power consumption screen image information and a plan editing screen image. A change edit screen image including the plan edit screen image indicated by the information is generated. Then, the screen transmission processing unit 158 causes the communication unit 142 to transmit change and edit screen image information indicating the change and edit screen image to the terminal device 110 that has sent the corresponding user authentication information.

The power management support device 140 described above can also be realized by, for example, the computer 10 shown in FIG. 3.

For example, the communication unit 142 can be realized by the processor 11 using the communication I/F 14. The storage unit 141 can be realized by the processor 11 using the memory 12 or the auxiliary storage device 13. The processing unit 150 can be implemented by loading a program stored in the auxiliary storage device 13 into the memory 12 and executing it by the processor 11.

FIG. 5 is a flowchart showing a process for generating a screen image for displaying power consumption in the first embodiment.

First, the power consumption acquisition unit 151 sequentially acquires power consumption information from the power meter 130 via the communication unit 142, associates the acquired power consumption information with the acquired time, and stores it in the storage unit 141. (S10).

Next, the plan management section 152 acquires production plan information from the production system 120 via the communication section 142, and provides the production plan information to the prediction section 154 (S11).

Next, the prediction unit 154 predicts future power consumption based on the production plan indicated by the production plan information from the plan management unit 152, and transmits future power consumption information indicating the future power consumption to the power consumption screen generation unit 155. (S12).

Next, the power consumption screen generation unit 155 displays the power consumption indicated by the power consumption information stored in the storage unit 141 and the future power consumption indicated by the future power consumption information from the prediction unit 154 in chronological order. A power consumption screen image is generated, and power consumption screen image information indicating the power consumption screen image is provided to the screen transmission processing unit 158 (S13).

Next, the user input acquisition unit 153 determines whether the content of the production plan has been changed, based on whether or not the changed part information has been acquired from the terminal device 110 via the communication unit 142 (S14). If the content of the production plan has been changed (Yes in S14), the process advances to step S15. In this case, the user input acquisition unit 153 provides the changed portion information acquired via the communication unit 142 to the prediction unit 154.

In step S15, the prediction unit 154 changes the production plan indicated by the production plan information from the plan management unit 152 with the contents indicated by the changed part information from the user input acquisition unit 153, and the production plan after the change is changed. The modified production plan predicts the modified future power consumption, which is the power that will be consumed by the production system 120 in the future. The prediction unit 154 then provides the power consumption screen generation unit 155 with changed future power consumption information indicating the predicted changed future power consumption.

Next, the power consumption screen generation unit 155 generates the power consumption indicated by the power consumption information stored in the storage unit 141 and the changed future power consumption indicated by the changed future power consumption information from the prediction unit 154 in a time series. A changed power consumption screen image represented by is generated, and changed power consumption screen image information indicating the changed power consumption screen image is provided to the screen transmission processing unit 158 (S16). Then, the process returns to step S14.

As described above, according to the flowchart shown in FIG. 5, when the user input acquisition unit 153 acquires changed portion information from any terminal device 110, the power consumption predicted in the future is changed. . Therefore, in all the terminal devices 110, it is possible to check the power consumption that has been changed based on the plan changed in any one of the terminal devices 110.

FIG. 6 is a flowchart showing a process in which the power management support device 140 receives access from the terminal device 110, displays power consumption, and transmits a screen for changing the contents of the plan in the first embodiment. be.

First, the user authority management unit 156 determines whether user authentication information has been acquired from the terminal device 110 via the communication unit 142 (S20). If the user authentication information has been acquired (Yes in S20), the process advances to step S21.

In step S21, the user authority management unit 156 uses the registered authentication information stored in the storage unit 141 to authenticate the acquired user authentication information, and determines whether the authentication is successful. If the authentication fails (No in S21), the user authority management unit 156 sends a login error to the terminal device 110 that sent the user authentication information, and returns the process to step S20. On the other hand, if the authentication is successful (Yes in S21), the process proceeds to step S22.

In step S22, the user authority management unit 156 determines the authority of the user identified by the user name included in the user authentication information that has been successfully authenticated, according to the user authority information stored in the storage unit 141. Accordingly, the content that can be changed by the user is specified, and changeable content information indicating the specified content is provided to the plan editing screen generation unit 157.

Next, the plan editing screen generation unit 157 generates a screen that can be changed, which is indicated by the changeable content information from the user authority management unit 156, out of the production plan indicated by the production plan information from the plan management unit 152. A plan editing screen image in which only the contents can be edited is generated, and plan editing screen image information indicating the plan editing screen image is provided to the screen transmission processing unit 158 (S23).

Next, the screen transmission processing unit 158 determines whether changed power consumption screen image information has been acquired from the power consumption screen generation unit 155 (S24). If the changed power consumption screen image information has not been acquired (No in S24), the process proceeds to step S25, and if the changed power consumption screen image information has been acquired (Yes in S24), the process proceeds to step S27. move on.

In step S25, the screen transmission processing unit 158 transmits the power consumption screen image indicated by the power consumption screen image information from the power consumption screen generation unit 155 and the plan editing screen indicated by the plan editing screen image information generated in step S23. Editing screen image information indicating an editing screen image including an image is generated.

Then, the screen transmission processing unit 158 causes the communication unit 142 to transmit the edited screen image information to the terminal device 110 that sent the corresponding user authentication information (S26). The process then proceeds to step S29.

On the other hand, in step S27, the screen transmission processing unit 158 sends a changed power consumption screen image indicated by the changed power consumption screen image information from the power consumption screen generation unit 155 and a changed power consumption screen image indicated by the plan editing screen image information generated in step S23. The change/edit screen image information indicating the change/edit screen image including the plan edit screen image to be created is generated.

Then, the screen transmission processing unit 158 causes the communication unit 142 to transmit the change/edit screen image information to the terminal device 110 that sent the corresponding user authentication information (S28). The process then proceeds to step S29.

In step S29, the screen transmission processing unit 158 determines whether changed power consumption screen image information has been acquired from the power consumption screen generation unit 155. When the changed power consumption screen image information is acquired (Yes in S29), the process advances to step S27.

As described above, according to the first embodiment, future power consumption can be predicted based on the production plan changed by the user using the terminal device 110.

In addition, since each user updates the predicted value of power consumption based on the production plan that is being changed, and the power consumption screen generation unit 155 regenerates the screen image based on the updated content, all users' terminal devices 110 The updated power consumption screen image will be distributed. Therefore, it is possible for each user to immediately determine whether or not the overall goal has been achieved in response to a power saving request for the entire production system 120 such as a factory. Therefore, it is possible to prevent changes in the production plan that would lead to excessive reduction in power consumption.

In addition, since a screen for changing the production plan is provided only to users who are determined to have the authority by the user authority management unit 156, editing of the production plan by users without authority is prevented. Can be done.

Furthermore, the time series of the predicted power consumption before the change, which is the output of the prediction unit 154 based on the production plan acquired from the production system 120, and the predicted power consumption prediction during the change, which is the output of the prediction unit based on the production plan being changed. By comparing with the time series of , it is possible to generate a screen that includes the planned amount of power consumption reduction for each production department. By generating such a screen, it is possible to share the contribution of each production department to reducing power consumption.

This is similar to the power consumption acquisition unit 151, user input acquisition unit 153, power consumption screen generation unit 155, user authority management unit 156, and screen transmission processing unit 158.

In the sixth embodiment, depending on the authority of the user identified by the user name included in the successfully authenticated user authentication information specified by the user authority management unit 156, the user is The contents that can be changed may include the contents of the power supply plan. In particular, in Embodiment 6, the content may include changing the usage plan of the equipment to be used.
Further, the user input acquisition unit 153 provides the changed part information from the terminal device 110 to the prediction unit 654, the plan management unit 652, and the supply performance management unit 661.

The plan management unit 652 performs the same processing as in Embodiment 1, as well as the following processing.
The plan management unit 652 acquires power supply plan information indicating a power supply plan from the power supply system 670 via the communication unit 142. The power supply plan information is given to the prediction unit 654 and the plan editing screen generation unit 657.

Here, the power supply plan indicates at least the amount and time to supply power to the production system 120 and the amount and time to store power in the power supply equipment. Furthermore, the power supply plan includes a usage plan that indicates the usage time of the usage equipment and the charging time of the storage battery used by the usage equipment.

Furthermore, the plan management unit 652 can change the power supply plan in the power supply system 670 by sending changed power supply plan information indicating the changed power supply plan to the power supply system 670 via the communication unit 142. It is assumed that the end of the change is input by the user into the terminal device 110.

The prediction unit 654 predicts the power to be consumed in the future by the production system 120 based on the production plan indicated by the production plan information from the plan management unit 652, and predicts the power to be consumed in the future by the production system 120 based on the power supply plan indicated by the power supply plan information from the plan management unit 652. , the future power consumption is determined by subtracting the power supplied from the power supply system 670 from the predicted power. The prediction unit 654 provides the power consumption screen generation unit 155 with future power consumption information indicating the specified future power consumption. The power supplied here includes the power supplied from the storage battery used by the device.

Further, upon receiving the changed part information from the user input acquisition part 153, the prediction unit 654 changes the production plan or the power supply plan to the content indicated by the changed part information. Then, the prediction unit 654 estimates the power supply system 670 from the power to be consumed in the future by the production system 120 according to at least one of the modified production plan that is the production plan after the change and the modified production plan that is the power supply plan after the change. Determine the changed future power consumption by subtracting the power that will be supplied in the future. The prediction unit 654 provides the power consumption screen generation unit 155 with changed future power consumption information indicating the specified changed future power consumption. In the sixth embodiment, the user of the device can use the power of the storage battery used by the device in the production system 120 by shortening the usage time or canceling the usage.

The plan editing screen generation unit 657 generates only the changeable content shown in the changeable content information from the user authority management unit 156 out of the production plan shown in the production plan information, or in the power supply plan information. A plan editing screen image is generated in which only the changeable contents indicated by the changeable contents information from the user authority management unit 156 can be edited out of the displayed power supply plan. The plan editing screen generation unit 657 provides the screen transmission processing unit 158 with plan editing screen image information indicating the generated plan editing screen image. Note that if there is no content that can be changed in the production plan by the user identified by the user name included in the user authentication information, the plan editing screen generation unit 657 will generate a message that there is no content that can be edited in the production plan. What is necessary is to generate a plan editing screen image that represents this. In addition, if there is no content that can be edited by the user identified by the user name included in the user authentication information in the power supply plan, the plan editing screen generation unit 557 determines that there is no content that can be edited in the power supply plan. What is necessary is to generate a plan editing screen image that represents this.

Here, in the sixth embodiment, the plan editing screen generation unit 657 can also make it possible to edit the usage time of the device to be used in the plan editing screen image. However, since other users may also use the equipment, it is necessary to prevent changes to the usage time of other users.

The supply record management unit 661 manages the record of users refraining from using the equipment in order to evaluate increasing the supply of power to the production system 120 by refraining from using the equipment. .

For example, when the supply performance management unit 661 receives changed part information from the user input acquisition unit 153, if the changed part information is a reduction in the usage time of the used equipment or a cancellation of the used equipment, the supply performance management unit 661 changes the actual performance to that of the used equipment. The information is aggregated for each user who made such changes.
The value to be aggregated here may be the total sum of the shortened time and canceled time over a predetermined period, or the predetermined amount of electricity supplied due to the shortening or cancellation of usage time. It may be the total amount for the period.
Furthermore, the aggregation may be performed for each individual or for each organization to which the user belongs.
Then, the supply performance management unit 661 sends performance value information indicating the aggregated value to the evaluation device 680 via the communication unit 142.

The storage unit 682 stores information and programs necessary for processing in the evaluation device 680.

The control unit 683 controls the processing in the evaluation device 680.
For example, the control unit 683 receives performance value information from the communication unit 681, and evaluates the user according to the performance value information. For example, the control unit 683 determines the amount of remuneration to the user according to the performance value information. Here, it is assumed that the larger the user's performance value is, the larger the remuneration amount will be.

The evaluation device 680 described above can also be realized by the computer 10 as shown in FIG. 3, for example.

For example, the communication unit 681 can be realized by the processor 11 using the communication I/F 14. The storage unit 682 can be realized by the processor 11 using the memory 12 or the auxiliary storage device 13. The control unit 683 can be implemented by loading a program stored in the auxiliary storage device 13 into the memory 12 and executing it by the processor 11.
