JP7524671B2 - Status display control device, status display control method, and computer program - Google Patents

Description

The present disclosure relates to a status display control device, a status display control method, and a computer program.

Conventionally, an energy management system (EMS) has been known for optimally controlling power equipment installed at consumer facilities such as factories in order to minimize power operation costs and _CO2 emissions at such facilities (see, for example, Patent Document 1).

Patent No. 6591133

Until now, the operating status of power equipment using EMS was confirmed by looking at a graph showing the time progression of the power equipment's output. For this reason, for example, if a failure occurred in a power equipment, a user such as a facility manager had to identify the cause of the failure by looking at the graph before and after the time the failure occurred.

However, although the graph contains information about the output of power devices, it does not contain information about how the power devices are connected. As a result, for example, if a fault occurs in the wiring between power devices, it is difficult for users to identify the cause of the fault from the graph.

This disclosure has been made in light of these circumstances, and aims to provide a status display control device, a status display control method, and a computer program that can assist in identifying the cause when a fault occurs.

A status display control device according to one aspect of the present disclosure includes a storage unit that stores operation status information indicating the operation status of multiple electric power devices installed in a customer facility in association with a time, a reception unit that receives a time designated by a user, an acquisition unit that acquires the operation status information at the designated time from the storage unit, and a display control unit that displays the operation status of the multiple electric power devices on a system diagram that shows the wiring system between the multiple electric power devices in the customer facility based on the acquired operation status information.

A status display control method according to another aspect of the present disclosure includes the steps of accepting a time designated by a user, acquiring operation status information indicating the operation status of a plurality of electric power devices installed in a customer facility at the designated time from a storage unit that stores the operation status information in association with a time, and displaying the operation status of the plurality of electric power devices on a system diagram showing a wiring system between the plurality of electric power devices in the customer facility based on the acquired operation status information.

A computer program according to another aspect of the present disclosure causes a computer to function as a reception unit that receives a time designated by a user, an acquisition unit that acquires operation status information indicating the operation status of multiple electric power devices installed at a customer facility at the designated time from a storage unit that stores the operation status information in association with a time, and a display control unit that displays the operation status of the multiple electric power devices on a system diagram that shows the wiring system between the multiple electric power devices at the customer facility based on the acquired operation status information.

It goes without saying that the computer program can be distributed on a non-transitory computer-readable recording medium such as a CD-ROM (Compact Disc-Read Only Memory) or via a communication network such as the Internet. The present disclosure can also be realized as a semiconductor integrated circuit that realizes part or all of the status display control device, or as a system that includes the status display control device.

This disclosure can help identify the cause when a problem occurs.

FIG. 2 is a diagram illustrating an example of the operation state information stored in the storage unit. FIG. 3 is a diagram showing an example of a display on the display screen of the display device. FIG. 4 is a flowchart illustrating an example of a procedure for recording operation status information by the status display control device according to the embodiment of the present disclosure.

Note that each of the embodiments described below shows a specific example of the present disclosure. The numerical values, shapes, materials, components, arrangement and connection forms of the components, steps, and order of steps shown in the following embodiments are examples and do not limit the present disclosure. In addition, among the components in the following embodiments, components that are not described in the independent claims are components that can be added arbitrarily. In addition, each figure is a schematic diagram and is not necessarily illustrated strictly.
In addition, the same components are denoted by the same reference numerals, and since their functions and names are also the same, their explanations will be omitted as appropriate.

[Configuration of the Status Display Control Device]
FIG. 1 is a block diagram illustrating an example of a hardware configuration and a functional configuration of a status display control device according to an embodiment of the present disclosure.

The status display control device 1 is a device that controls the display of the operating status of multiple electric power devices installed in a customer facility such as a factory. The multiple electric power devices are controlled by a control device such as an EMS.

The consumer facility is not limited to a factory, and may be, for example, an apartment building, a building, a home, a group of homes, etc. Furthermore, the electric power device may be, for example, a generator, a storage battery, etc.
The generators include gas generators, fuel cells, and generators that generate electricity using renewable energy sources such as solar and wind power.

The storage battery includes secondary batteries such as redox flow (RF) batteries, lithium ion batteries, molten salt batteries, and lead acid batteries. The storage battery stores the electricity generated by the generator.

Referring to FIG. 1, the status display control device 1 includes a control unit 10, an input/output I/F (interface) unit 20, a communication I/F unit 25, and a storage unit 30. The control unit 10, the input/output I/F unit 20, the communication I/F unit 25, and the storage unit 30 are interconnected via a bus 19.

The control unit 10 includes a CPU (Central Processing Unit) and is equipped with an operating status recording unit 11, a video recording unit 12, a reception unit 13, an acquisition unit 14, and a display control unit 15 as functional processing units realized by executing a computer program pre-stored in the storage unit 30.

The input/output I/F unit 20 is an interface for connecting a display device 2, such as a liquid crystal display device, and an input device 3, such as a keyboard or mouse, to the status display control device 1.

The communication I/F unit 25 is an interface for communicating with the control device 4 such as an EMS and the camera 5 .
Here, the control device 4 controls the start-up and stop of each piece of electric power equipment installed in the customer facility and the output of each piece of electric power equipment in accordance with a predetermined operation plan.

Camera 5 photographs the installation location of the electric power equipment. Specifically, camera 5 photographs the installation location of a generator whose output is affected by weather. For example, camera 5 photographs the installation location of a solar power generator that generates electricity using sunlight, which is a renewable energy source. Note that if the electric power equipment includes a wind power generator that generates electricity using wind power, which is a renewable energy source, camera 5 may also photograph the installation location of the wind power generator.

The storage unit 30 is composed of a volatile memory element such as SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory), a non-volatile memory element such as flash memory or EEPROM (Electrically Erasable Programmable Read-Only Memory), or a magnetic storage device such as a hard disk. The storage unit 30 stores the computer programs executed by the control unit 10 and the data required for their execution.

The video recording unit 12 receives video data captured by the camera 5 from the camera 5 via the communication I/F unit 25, and records the received video data in the memory unit 30.

The operation status recording unit 11 records operation status information indicating the operation status of multiple electric power devices installed in the consumer facility in the memory unit 30 in association with time.

FIG. 2 is a diagram showing an example of the operating state information stored in the storage unit 30. As shown in FIG.
Each record of the operating status information includes "date and time,""operatingstatus,""target electric device,""alarminformation,""videodata," and "weather information."

The operation status recording unit 11 records the date and time when the "operation status", "target electric equipment", "alarm information", "video data", and "weather information" were acquired in the "date and time" column. For example, this information was acquired at 6:00:00 on March 24, 2020 and 6:01:00 on March 24, 2020.

The operation status recording unit 11 receives the operation status of each electric power device from the control device 4 via the communication I/F unit 25, and records it in the "operation status" column. For example, the output of the storage battery acquired at 06:00:00 on March 24, 2020 is 0 kW, and the output of the No. 1 generator is 50 kW. The "operation status" column also records the operation status of electric power devices other than the storage battery and No. 1 generator installed at the consumer facility.

The operation status recording unit 11 receives information from the control device 4 via the communication I/F unit 25 as to whether each electric power device is a target electric power device, and records the information in the "Target electric power device" column. Here, a target electric power device is an electric power device that is the target of control by the control device 4.

For example, if an electric power device is in an activated state or a standby state and is in a state in which it can accept a control command from the control device 4, that electric power device is regarded as a target electric power device. For example, the control device 4 regards an electric power device that has transmitted a response signal in response to a control command as a target electric power device.

On the other hand, if the power supply of the electric power equipment is turned off and the electric power equipment is stopped, or if the electric power equipment is broken, and the electric power equipment is in a state in which it cannot accept a control command from the control device 4, the electric power equipment is not considered to be a target electric power equipment. For example, the control device 4 removes from the list of target electric power equipment an electric power equipment that does not transmit a response signal to a control command.

In the "Target Electric Equipment" column, target electric equipment is indicated with TRUE, and electric equipment that is not a target electric equipment is indicated with FALSE. For example, it is shown that at 06:00:00 on March 24, 2020, the storage battery is not a target electric equipment, and the No. 1 generator is a target electric equipment. The "Target Electric Equipment" column also records information on whether electric equipment other than the storage battery and No. 1 generator installed at the consumer facility is a target electric equipment.

The operation status recording unit 11 receives alarm information for each power device, consumer facility, etc. from the control device 4 via the communication I/F unit 25, and records it in the "alarm information" column. For example, the operation status recording unit 11 obtains alarm information for "minor battery failure" at 6:00:00 on March 24, 2020 and 6:01:00 on March 24, 2020.

The operating status recording unit 11 records the file name or link destination of the video data recorded by the video recording unit 12 in the "Video Data" column. For example, the file name of the video data acquired at 6:00:00 on March 24, 2020 is "V200324060000". Also, the file name of the video data acquired at 6:01:00 on March 24, 2020 is "V200324060100".

The operation status recording unit 11 receives weather information for the consumer facility from the control device 4 or a weather server (not shown) via the communication I/F unit 25, and records the information in the "weather information" column. For example, the temperature at 06:00:00 on March 24, 2020 is 13°C and the humidity is 35%. The temperature at 06:01:00 on March 24, 2020 is 13°C and the humidity is 34%. When pinpoint weather information can be obtained, it is preferable for the operation status recording unit 11 to receive and record weather information for the installation locations of solar power generators or wind power generators whose output is affected by weather.

Referring again to FIG. 1, the reception unit 13 receives the time specified by the user using the input device 3 via the input/output I/F unit 20. Note that the time specified by the user also includes the day.

The acquisition unit 14 acquires the operation status information at the time specified by the user that was accepted by the acceptance unit 13 by reading it from the storage unit 30. For example, when the specified time is 6:00:00 on March 24, 2020, the acquisition unit 14 reads the record of the operation status information at that time. According to the example shown in FIG. 2, the read record includes information such as the operation status of the storage battery being 0 kW, the operation status of the No. 1 generator being 50 kW, the storage battery not being a target electric power device, the No. 1 generator being a target electric power device, and a minor battery failure alarm being issued.

The acquisition unit 14 also acquires all warning information for the day indicated by the specified time by reading it from the storage unit 30 together with date and time information. For example, when the specified time is 6:00:00 on March 24, 2020, the acquisition unit 14 reads all warning information for March 24, 2020. The range of time to be read is not limited to one day, and may be longer or shorter. For example, the acquisition unit 14 may read warning information for six hours before and after the specified time.

The display control unit 15 displays, on the display screen of the display device 2, a system diagram showing the wiring system (power distribution system) between multiple electric power devices in the customer facility. The display control unit 15 also displays the operating status of multiple electric power devices on the system diagram based on the operating status information acquired by the acquisition unit 14. Note that the information on the system diagram is assumed to be stored in the memory unit 30.

FIG. 3 is a diagram showing an example of a display on the display screen of the display device 2. As shown in FIG.
On the display screen, a system diagram 40, an alarm time chart 50, an operation menu 60, a camera image 70, weather information 80, and an alarm list 90 are displayed.

The operation menu 60 is a field for the user to specify a time. The user can specify a time by inputting a date and time in the display time field of the operation menu 60. In this example, it is assumed that 10:00:00 on March 24, 2020 is specified as the display time. Furthermore, when the user presses the play button 61, the display time automatically advances. When the user presses the fast-forward button 62, the display time is fast-forwarded. For example, the display time advances at twice the speed compared to when the play button 61 is pressed. Furthermore, when the user presses the rewind button 63, the display time is rewound. The current playback speed is displayed in the playback speed display field 64.

The system diagram 40 shows the wiring system of multiple electric power devices, namely, a No. 1 generator 41, a No. 2 generator 42, a No. 3 generator 43, a solar power generator 44, a storage battery 45, a factory 46, an office building 47, and a commercial power source 49. The factory 46 and the office building 47 are load devices.

In the system diagram 40, at the time shown in the operation menu 60, the word "connected" or "disconnected" and a switch indicate whether each power device is connected to the power distribution system in the customer facility. For example, the No. 1 generator 41, the No. 3 generator 43, the solar generator 44, the factory 46, and the office building 47 are connected to the power distribution system. Therefore, the word "connected" is written near these power devices, and the switches of the connection lines between these power devices and the power distribution system are closed. On the other hand, the No. 2 generator 42 and the storage battery 45 are not connected to the power distribution system. Therefore, the word "disconnected" is written near these power devices, and the switches of the connection lines between these power devices and the power distribution system are open.

The flow of electricity at the displayed time shown in the operation menu 60 is also indicated by arrows. For example, arrows extend from the No. 1 generator 41, the No. 3 generator 43, and the solar generator 44 toward the power distribution system. This indicates that the electricity generated by these generators is being output to the power distribution system. Arrows also extend from the power distribution system toward the factory 46 and the office building 47. This indicates that the factory 46 and the office building 47 are receiving electricity from the power distribution system.

The output of each power device at the display time shown in the operation menu 60 is also displayed on the system diagram. For example, the output of generator No. 1 41 is 500 kW, the output of generator No. 2 42 is 0 kW, the output of generator No. 3 43 is 500 kW, and the output of solar power generator 44 is 50 kW. In addition, if the power device is a load device, the power consumption of the load device is displayed. For example, the power consumption of factory 46 is 1200 kW, and the power consumption of office building 47 is 140 kW.

The thickness of the connection lines between each power device and the power distribution system indicates the amount of output or power consumption. For example, the output of generator No. 1 41 is greater than the output of solar generator 44, so the connection lines of generator No. 1 41 are thicker than the connection lines of solar generator 44. Also, the power consumption of factory 46 is greater than the power consumption of office building 47, so the connection lines of factory 46 are thicker than the connection lines of office building 47.

The target electric power equipment of the control device 4 at the display time shown in the operation menu 60 is indicated by a dashed arrow. In other words, the No. 1 generator 41, the No. 3 generator 43, and the solar power generator 44, which have dashed arrows extending from the control device 4, are the target electric power equipment.

The alarm time chart 50 is a time chart showing the time during which an alarm is issued for each type of alarm. The horizontal axis of the alarm time chart 50 indicates the time of day and time of the alarm information acquired by the acquisition unit 14, and the vertical axis indicates the type of alarm. The horizontal bars on the alarm time chart 50 indicate the time period during which an alarm is issued. For example, it can be seen that the alarm "minor battery failure" is issued between approximately 2:00 and 17:00. The bar 51 indicates the current display time, which is the same as the display time shown in the operation menu 60. The user can also change and specify the display time by moving the bar 51 left or right.

The camera image 70 displays an image acquired at the display time, that is, an image captured by the camera 5 at the display time.
The weather information acquired on the display device is displayed in the weather information 80. The weather information 80 includes, for example, information on temperature, humidity, solar radiation intensity, wind speed, and wind direction.

The alarm list 90 displays a list of alarms that have occurred on the display device. For example, the alarms that have occurred as of 10:00:00 on March 24, 2020 are displayed as a minor battery failure and a demand alarm.

[Recording process of operation status information]
FIG. 4 is a flowchart showing an example of a procedure for a recording process of operating status information by the status display control device 1 according to an embodiment of the present disclosure.
The operation status recording unit 11 acquires the operation status of each electric device from the control device 4 via the communication I/F unit 25 (step S1).
The operation status recording unit 11 acquires information as to whether each electric power device is a target electric power device from the control device 4 via the communication I/F unit 25 (step S2).
The operation status recording unit 11 acquires alarm information for each electric power device, consumer facility, etc. from the control device 4 via the communication I/F unit 25 (step S3).

The video recording unit 12 acquires the video data captured by the camera 5 from the camera 5 via the communication I/F unit 25, and records the acquired video data in the storage unit 30 (step S4).
The operation status recording unit 11 acquires weather information for the customer facility from a weather server (not shown) via the communication I/F unit 25 (step S5).
The operating status recording unit 11 creates operating status information based on the data acquired in steps S1 to S5 and records the information in the storage unit 30 (S6).

2, the operating status recording unit 11 records the date and time when these data were acquired in the "date and time" column, records the operating status acquired in step S1 in the "operating status" column, and records the information of the target electric equipment acquired in step S2 in the "target electric equipment" column. In addition, the operating status recording unit 11 records the alarm information acquired in step S3 in the "alarm information" column, records the file name of the video data acquired in step S4 in the "video data" column, and records the weather information acquired in step S5 in the "weather information" column.
The status display control device 1 repeatedly executes the processes from step S1 to step S6 periodically (for example, once a minute) (loop A).

[Display control process for display screen]
FIG. 5 is a flowchart showing an example of a procedure of a display control process on the display screen of the display device 2 by the status display control device 1 according to the embodiment of the present disclosure.
The display control process will be described below with reference to FIGS.

The acquisition unit 14 determines whether or not a display time has been designated (step S11). For example, if a time has been input in the display time field in the operation menu 60 on the display screen shown in Fig. 3, or if a display time has been designated by the bar 51 on the alarm time chart 50, it is determined that a display time has been designated.
If it is determined that the display time is not specified (NO in step S11), the acquisition unit 14 waits until the display time is specified.

If it is determined that a display time has been specified (YES in step S11), the acquisition unit 14 reads out the operation status information for the specified display time from the storage unit 30. The acquisition unit 14 also reads out all the warning information for the day indicated by the display time together with date and time information from the storage unit 30 (step S12).

The display control unit 15 displays on the display screen a system diagram 40 with the operating status and information on the target electric power equipment superimposed based on the operating status information at the display time read in step S12 (step S13).

The display control unit 15 displays the warning time chart 50 based on all warning information for the day indicated by the display time read in step S12 (step S14).

The display control unit 15 reads the video data of the file name indicated in the operation status information from the storage unit 30 based on the operation status information at the display time read in step S12, and displays the read video data in the camera video 70 column on the display screen (step S15).

The display control unit 15 displays the weather information 80 on the display screen based on the operation status information at the display time read out in step S12 (step S16).
The display control unit 15 displays the alarm list 90 on the display screen based on the operation status information at the display time read out in step S12 (step S17).

The control unit 10 determines whether the end condition of the display control process is satisfied (step S18). For example, the control unit 10 determines that the end condition is satisfied if the user inputs an instruction to end the display control process, and otherwise determines that the end condition is not satisfied.

If it is determined that the termination condition is not met (NO in step S18), the status display control device 1 repeats the processing from step S11 onward. If it is determined that the termination condition is met (YES in step S18), the status display control device 1 ends the display control processing.

[Effects of the embodiment]
As described above, according to the first embodiment of the present disclosure, the operation state of the electric power equipment at a time specified by the user is displayed on the system diagram 40 that shows the wiring system between the electric power equipment. Therefore, the user can check the operation state of the electric power equipment at any time in the past on the system diagram 40. This allows the user to identify, for example, an electric power equipment that is stopped on the system diagram 40. In addition, the user can check the operation states of other electric power equipment connected to the identified electric power equipment, and can check, for example, whether the cause of the stoppage is due to a break in the distribution system or a failure of the electric power equipment. This can assist in identifying the cause when a failure occurs.

In addition, on the display screen of the display device 2 shown in FIG. 3, the target electric power equipment is indicated by a dashed arrow. This allows the user to check on the system diagram 40 the electric power equipment that is the target of control of a control device such as an EMS. This allows the user to know, for example, electric power equipment that should be the target of control but is not, and this information can be used to track down the cause when a fault occurs.

The display screen also displays an alarm time chart 50. This allows the user to easily identify the time when an alarm occurred. This allows the user to specify any time when an alarm occurred and easily check the operating status of the power equipment at that time on the system diagram 40.

The display screen also displays the output of the power equipment on the system diagram 40. This allows the user to check the output of the power equipment on the system diagram 40 along with the operating status of the power equipment at any time.

The thickness of the connection lines of the power devices also indicates the amount of output from the power devices. This allows the user to intuitively understand the amount of output from the power devices by looking at the thickness of the connection lines.

The direction of the power in the power equipment is also indicated by the direction of the arrow shown on the connection line of the power equipment. This allows the user to intuitively understand the direction in which the power in the power equipment flows by looking at the direction of the arrow.

The display screen also displays a camera image 70 taken at the location where the solar power generator is installed. This allows the user to understand the operating status of the solar power generator while checking the weather at the installation location. For example, if the weather is fine but the output of the solar power generator is low, the user can consider the possibility of a malfunction of the solar power generator.

Although the status display control device 1 according to the embodiment of the present disclosure has been described above, the present disclosure is not limited to this embodiment.
For example, the functions of the above-described status display control device 1 may be included in a control device 4 such as an EMS.

In addition, some or all of the components constituting the status display control device 1 may be composed of semiconductor devices such as one or more system LSIs.
