When changing the display mode of a part or symbol on a monitoring screen created in the past, editing work is performed to update the attributes assigned to the part or symbol. In order to achieve the desired display mode, it is important to understand the changes in attributes due to the update, to check whether the previous update was appropriate, or, if an abnormality occurs in the display mode, to check the cause of the abnormality. In other words, when updating attributes, it is important to perform editing work while understanding the changes in attributes from the past due to the update.

In the case of the conventional technology disclosed in Patent Document 1, in order to check attribute changes from the past, the worker performing the editing work must search for data indicating the details of updates made to the parts or symbols in the editing history of the monitoring screen. In this case, the efficiency of the editing work deteriorates because the work of checking attribute changes from the past is required in addition to the editing work. For this reason, with the conventional technology, there was a problem in that it was difficult to improve the efficiency of editing work on the monitoring screen.

The present disclosure has been made in consideration of the above, and aims to provide a monitoring screen creation support system that can make editing work of monitoring screens more efficient.

In order to solve the above-mentioned problems and achieve the objective, the monitoring screen creation support system according to the present disclosure is a monitoring screen creation support system that supports the creation of a monitoring screen displayed by a monitoring control device that monitors and controls a monitoring control target. The monitoring screen creation support system according to the present disclosure includes an attribute setting unit that assigns attributes of the display mode on the monitoring screen to symbols that represent components of the monitoring control target on the monitoring screen, an attribute editing unit that updates the attributes assigned to the symbols by the attribute setting, a difference information storage unit that stores difference information indicating the difference between the attributes before and after the update, and a difference display unit that acquires the difference information and displays the difference location, which is the position of the symbol whose attribute has been updated, and the difference information on the editing screen where editing work of the monitoring screen is performed.

The monitoring screen creation support system disclosed herein has the effect of making the editing of monitoring screens more efficient.

Embodiment 1.
Fig. 1 is a diagram showing an example of the configuration of a monitoring screen creation support system 1 according to a first embodiment. The monitoring screen creation support system 1 includes a monitoring screen creation support device 2 and a terminal device 3. A monitoring control device 4, a control device 6, and a gateway 7 shown in Fig. 1 constitute a monitoring control system. The monitoring control device 4 monitors and controls a monitoring control target. The monitoring control target is a facility installed at a site.

The monitored and controlled object is, for example, a plant such as a power distribution plant or an electric power plant, a substation, a power plant, a water treatment facility, or a railway facility. The monitoring and control device 4 controls the equipment that constitutes the facility and monitors the status of the equipment. When the monitored and controlled object is a water treatment facility, the equipment is, for example, a pump, a solenoid valve, or a blower. When the monitored and controlled object is a substation, the equipment is, for example, a circuit breaker or a disconnecting switch.

A plurality of sensors 5 are installed in the facility for monitoring the facility. Each sensor 5 measures the state of the facility and outputs a measurement value. When the monitored and controlled object is a water treatment facility, the plurality of sensors 5 include various sensors such as a flow rate sensor, a water level sensor, or a characteristic detection sensor. When the monitored and controlled object is a sewage treatment plant, the characteristic detection sensor is a concentration sensor that detects the concentration of _NH3 , a concentration sensor that detects the concentration of _NH4 +, or a concentration sensor that detects the concentration of ammoniacal nitrogen. When the monitored and controlled object is a substation, the plurality of sensors 5 include various sensors such as a voltage sensor, a current sensor, or a temperature sensor.

At the site, a control device 6 that monitors and controls the equipment at the site and a gateway 7 are installed. The gateway 7 connects the control device 6 and the monitoring control device 4 so that they can communicate with each other via a network. The control device 6 transmits monitoring data including measurement values output from each sensor 5 to the monitoring control device 4 via the gateway 7. The monitoring control device 4 acquires the monitoring data transmitted from the control device 6. In the first embodiment, the network is, for example, a WAN (Wide Area Network) such as the Internet. The network may also be a LAN (Local Area Network).

The monitoring and control device 4 is constructed in a cloud environment. The cloud environment includes computer resources provided in a cloud service platform. The monitoring and control device 4 is composed of, for example, one or more cloud servers. A cloud server is a server constructed in the cloud environment.

The monitoring and control device 4 is connected to a user terminal, which is a terminal used by a user of the monitoring and control system, via a network so that they can communicate with each other. A user is someone who uses the monitoring and control system to perform monitoring and control work for equipment. Illustration of the user terminal is omitted. The monitoring and control device 4 displays a monitoring screen on the user terminal by transmitting monitoring data indicating the status of the monitored and controlled object to the user terminal.

The monitoring screen creation support device 2 supports the creation of a monitoring screen to be displayed by the monitoring control device 4. The monitoring screen creation support device 2 is constructed in a cloud environment, similar to the monitoring control device 4. The monitoring screen creation support device 2 is configured, for example, by one or more cloud servers. Note that in the first embodiment, the monitoring screen displayed by the monitoring control device 4 includes a monitoring screen that is displayed on a user terminal by the monitoring control device 4.

The terminal device 3 is a personal computer operated by an operator who creates the monitoring screen. The monitoring screen creation support device 2 and the terminal device 3 are connected to each other via a network so that they can communicate with each other. The monitoring screen creation support device 2 is also connected to the monitoring control device 4.

The monitoring screen creation support device 2 executes a monitoring screen creation support program, which is a program that supports the creation of a monitoring screen. The worker creates a monitoring screen using the monitoring screen creation support program by operating the terminal device 3. That is, the terminal device 3 uses the monitoring screen creation support program via a network. Note that the usage form of the monitoring screen creation support program is not limited to via a network, and the monitoring screen creation support program may be installed on a personal computer operated by the worker, and the personal computer may execute the monitoring screen creation support program. The worker performs editing work on the monitoring screen by operating the editing screen displayed on the terminal device 3.

FIG. 2 is a diagram showing an example of the configuration of the monitoring screen creation support device 2 according to the first embodiment. The monitoring screen creation support device 2 includes an input unit 10, an input information analysis unit 11, a screen editing unit 12, a difference information management unit 13, a screen data management unit 14, and an output unit 15.

Information from a device external to the monitoring screen creation support device 2 is input to the input unit 10. The terminal device 3 transmits information input to the terminal device 3 by an operator operating the terminal device 3 to the monitoring screen creation support device 2. The information input to the terminal device 3 is input to the input unit 10 by the input unit 10 receiving the information transmitted by the terminal device 3. The input unit 10 outputs the information input to the input unit 10 to the input information analysis unit 11. The input information analysis unit 11 analyzes the information obtained from the input unit 10.

The screen editing unit 12 executes processing according to the operation of the editing screen by the worker. The worker edits the monitoring screen by operating the editing screen. Editing the monitoring screen includes arranging parts, which are elements that make up the monitoring screen, assigning attributes of the display mode of the monitoring screen to parts or symbols, assigning signals to symbols, and assigning logic to attributes. Symbols represent components that are the subject of monitoring and control. Components that are the subject of monitoring and control are, for example, devices that make up a facility. Parts are shapes that make up symbols.

Logic is information that indicates the behavior of symbols according to signals. Symbol behavior refers to changes in the way symbols are displayed, such as changes in the color of a part, changes in the size of a part, changes in the shape of a part, or whether or not it blinks. On the monitoring screen, the status of the object being monitored and controlled is represented by the behavior of the symbol.

The screen editing unit 12 includes an attribute editing unit 20, a part placement processing unit 21, a part information storage unit 22, a logic assignment processing unit 23, and a logic storage unit 24. The input information analysis unit 11 outputs information input for editing the monitoring screen to the screen editing unit 12. The information from the input information analysis unit 11 is input to the attribute editing unit 20.

The attribute editing unit 20 performs attribute setting to assign attributes of the display mode on the monitoring screen to symbols on the monitoring screen, and updates the attributes assigned to the symbols by the attribute setting. Attributes assigned to symbols include attributes of the parts that make up the symbol and the symbol attributes. Part attributes include color, thickness, size, position on the monitoring screen, etc. Symbol attributes include behavior in response to traffic lights.

Information about part selection and part position are input to the part placement processing unit 21 via the attribute editing unit 20. The part placement processing unit 21 performs a process of selecting the part indicated in the input information according to the input information and a process of placing the part at the position indicated in the input information, thereby generating part information. The part information includes information indicating the type of part and information indicating the position of the part. The parts are placed by the part placement processing unit 21 to form a symbol that is displayed on the monitoring screen. The part information is stored in the part information storage unit 22.

When information about logic allocation is input to the attribute editing unit 20, the attribute editing unit 20 outputs the input information to the logic assignment processing unit 23. The logic assignment processing unit 23 performs processing to assign logic to symbols according to the input information. Information about the logic assigned to the symbol is stored in the logic storage unit 24.

Information indicating the contents of the edits made by the processes in the attribute editing unit 20, the part placement processing unit 21, and the logic assignment processing unit 23 is output from the attribute editing unit 20 to the difference information management unit 13, the screen data management unit 14, and the output unit 15. The output unit 15 transmits information indicating the contents of the edits to the terminal device 3. The terminal device 3 receives the information from the output unit 15, and displays the status of the editing of the monitoring screen on the editing screen based on the received information.

The screen data management unit 14 manages screen data, which is data indicating the contents of the monitoring screen. The screen data management unit 14 includes a screen data acquisition unit 31 and a screen data storage unit 32. The screen data acquisition unit 31 acquires information indicating the contents of the edits from the attribute editing unit 20. When an instruction to save the edited monitoring screen is given by an operator's operation, the screen data acquisition unit 31 outputs the screen data for the edited monitoring screen to the screen data storage unit 32. The screen data management unit 14 saves the screen data by storing the screen data in the screen data storage unit 32.

The screen data acquisition unit 31 acquires the stored screen data by reading the screen data from the screen data storage unit 32. The screen data acquisition unit 31 outputs the screen data to the output unit 15. The output unit 15 transmits the screen data to the monitoring control device 4. The monitoring control device 4 receives the screen data and displays a monitoring screen based on the received screen data.

When an operator instructs updating the attributes of previously created screen data, the attribute editing unit 20 instructs the screen data acquisition unit 31 to read the screen data. The screen data acquisition unit 31 acquires the saved screen data by reading the screen data from the screen data storage unit 32 in accordance with the instruction from the attribute editing unit 20. The screen data acquisition unit 31 outputs the screen data to the screen editing unit 12. When the attribute editing unit 20 acquires the screen data, it updates the attributes in accordance with the operator's operation. When an operator instructs saving the monitoring screen with updated attributes, the screen data acquisition unit 31 outputs the screen data for the edited monitoring screen to the screen data storage unit 32. The screen data management unit 14 saves the screen data for the monitoring screen with updated attributes by storing the screen data in the screen data storage unit 32.

The difference information management unit 13 manages difference information. The difference information is information that indicates the difference between an attribute before the update and an attribute after the update when the attribute is updated. The difference information management unit 13 includes a data accumulation unit 25, a difference analysis unit 26, a difference information storage unit 27, a difference information acquisition unit 28, a difference information formatting unit 29, and a difference display unit 30.

When editing is performed to update attributes of previously created screen data, the data accumulation unit 25 acquires information indicating the content of the edit from the attribute editing unit 20. The data accumulation unit 25 accumulates the edited screen data. The data accumulation unit 25 also acquires screen data at the start of editing from the attribute editing unit 20. When an instruction to save the edited monitoring screen is given by an operator's operation, the data accumulation unit 25 outputs the screen data at the start of editing and the edited screen data at the time the instruction to save was given to the difference analysis unit 26.

The difference analysis unit 26 finds the difference between the attributes of each part and each symbol at the start of editing and the attributes of each part and each symbol after editing by analyzing the screen data at the start of editing and the edited screen data at the time when saving is instructed. That is, the difference analysis unit 26 finds the difference between the attributes before and after updating for each part and each symbol. The difference analysis unit 26 outputs difference information indicating the found difference to the difference information storage unit 27. The difference information management unit 13 saves the difference information by storing the difference information in the difference information storage unit 27.

The difference information acquisition unit 28 acquires difference information by reading out difference information from the difference information storage unit 27. The difference information acquisition unit 28 outputs the acquired difference information to the difference information formatting unit 29. The difference information formatting unit 29 formats the difference information acquired from the difference information acquisition unit 28 for display on the editing screen. The difference information formatting unit 29 outputs the formatted difference information to the difference display unit 30. The difference information formatting unit 29 outputs information on the difference location, which is information indicating the position of the symbol whose attribute has been updated, and an update history, which is a history of the attribute being updated, to the difference display unit 30.

The difference display unit 30 performs processing for displaying the difference locations on the editing screen, processing for displaying the contents of the difference information on the editing screen, and processing for displaying the update history on the editing screen. The difference display unit 30 outputs difference display information, which is information for displaying each of the difference locations and the difference information on the editing screen, to the output unit 15. The difference display unit 30 outputs update history information for displaying the update history on the editing screen to the output unit 15. The output unit 15 outputs the update history information and the difference display information to the terminal device 3. The terminal device 3 receives the update history information and displays the update history according to the received update history information. The terminal device 3 also receives the difference display information and displays the difference locations and the difference information on the editing screen according to the received difference display information. In this way, the difference display unit 30 acquires the difference information and displays the difference locations and the difference information on the editing screen.

FIG. 3 is a first diagram showing an example of an editing screen 40 displayed by the monitoring screen creation support system 1 according to the first embodiment. The editing screen 40 displays a monitoring screen 41 that is the subject of editing. The editing screen 40 also includes a button group 42 for selecting a part to be placed on the monitoring screen 41, and a button 43 for displaying an update history of attributes. Each of the multiple buttons included in the button group 42 is a button for selecting a part from among the parts prepared in advance.

When the worker presses a button from the button group 42 for a part to be placed on the monitoring screen 41, the part corresponding to the pressed button is displayed on the monitoring screen 41. By operating the displayed part, for example by dragging and dropping the part, the part is placed in a position corresponding to the operation. In this way, a part is selected by an operation on the editing screen 40, and the selected part is placed on the monitoring screen 41 in a position corresponding to the operation. A symbol is formed by appropriately placing parts on the monitoring screen 41. For example, the symbol 44 shown in FIG. 3 represents a solenoid valve.

For each part that constitutes a symbol, the attributes of the part include coordinates, which are position information that indicates the part's position on the monitoring screen 41. The position information is set according to the above-mentioned operation for determining the part's position. Note that symbols include those that consist of one part and those that consist of multiple parts.

The part placement processing unit 21 selects parts and places the selected parts according to the operation of the worker. The attribute editing unit 20 sets the display mode of the parts on the monitoring screen 41, such as color or size, according to the operation of the worker. The logic assignment processing unit 23 assigns signals to symbols and assigns logic according to the operation of the worker.

On the monitoring screen 41, a number of symbols are arranged to depict a diagram of the equipment to be monitored and controlled. The monitoring screen 41 shown in FIG. 3 shows two water tanks, a pipe that sends water to one of the water tanks, a pipe that sends water pumped from one water tank to the other water tank, a pipe that sends water from the other water tank, and solenoid valves installed in each pipe. Note that in FIG. 3, the black symbols and the white symbols are displayed in different colors. For example, the symbol representing the solenoid valve is displayed in a different color depending on whether it is in a closed state or an open state. In this case, logic is set for the symbol representing the solenoid valve to display different colors for signals indicating a closed state and signals indicating an open state.

Figure 4 is a second diagram showing an example of an editing screen 40 displayed by the monitoring screen creation support system 1 according to the first embodiment. When the history display button 43 is pressed from the state shown in Figure 3, an update history display area 45 that displays the update history is displayed on the editing screen 40 as shown in Figure 4.

The update history display area 45 displays the update history in chronological order. The update history is a list of difference numbers and update dates and times, which are the dates and times when the updates shown in the difference information were made. The difference numbers are numbers assigned to the difference information managed by the difference information management unit 13. The difference numbers are assigned to the difference information when it is saved in the difference information management unit 13. Different difference numbers are assigned to difference information saved at different dates and times. For this reason, difference information saved at different dates and times can be identified by the difference numbers. Here, the date and time are indicated by the year, month, day, hour, minute, and second.

Each line of the update history in the update history display area 45 corresponds to difference information for each difference number. When the worker clicks on a line of the update history in the update history display area 45, an object 46 is displayed surrounding the updated symbol shown in the difference information for the difference information corresponding to the clicked line. The object 46 represents the difference location. Figure 4 shows a state in which an object 46 is displayed surrounding the symbol 44, which is the difference location, when the line with difference number "1" in the update history display area 45 is clicked. Also, in Figure 4, the halftone tone applied to the line with difference number "1" indicates that the line has been clicked, causing it to be a different color from the other lines in the update history display area 45.

Furthermore, if an update causes a difference in the attributes of symbol 44, a mark 47 indicating that a difference has occurred in the attributes of symbol 44 is displayed near object 46. When mark 47 is clicked, a speech bubble 48 displaying an overview of the difference information about symbol 44 is displayed on editing screen 40. The speech bubble 48 illustrated in FIG. 4 indicates that the logic assigned to the attribute named "abnormality determination" has been changed from "logic 1" to "logic 2." "Logic 1" and "logic 2" are logics that determine whether or not an abnormality has occurred in the equipment based on the value indicated by the signal.

Furthermore, by clicking on the word "View details" displayed in speech bubble 48, a window showing detailed information about the difference information outlined in speech bubble 48 is displayed on editing screen 40. For example, the threshold value that is the standard for determining whether or not there is an abnormality is displayed for each of "Logic 1" and "Logic 2" in the window. If the threshold value differs between "Logic 1" and "Logic 2", it is possible to confirm by referring to the window that the threshold value has been changed by changing the logic from "Logic 1" to "Logic 2".

In this way, the difference display unit 30 displays the difference points for the update time specified from the update history by displaying the object 46. This allows the worker to easily check the update points where attributes have been updated while performing editing work on the editing screen 40. The difference display unit 30 also displays difference information for the update time specified from the update history by displaying the speech bubble 48, or by displaying the speech bubble 48 and a window. This allows the worker to easily check the changes in attributes from the past due to updates while performing editing work on the editing screen 40.

Figure 5 is a diagram for explaining screen data managed by the screen data management unit 14 in the monitoring screen creation support device 2 according to the first embodiment. A screen number is assigned to the monitoring screen created by the screen editing unit 12 to identify the monitoring screen. The screen number, screen name, save date and time, and screen data are stored in the screen data storage unit 32 of the screen data management unit 14 in a linked manner. The screen name is a name assigned to each monitoring screen created by the screen editing unit 12. In Figure 5, for example, "Screen 1" is the screen name assigned to the monitoring screen with screen number "1".

The saved date and time is the date and time when the screen data is saved in the screen data storage unit 32. For screen data whose attributes have been updated, the saved date and time is the date and time when the screen data was saved the last time it was updated. The screen editing unit 12 manages the screen data of each monitoring screen by saving the screen data for each monitoring screen. For example, the screen data of "Screen 1" is saved in association with the screen number "1", the screen name "Screen 1", and the saved date and time of "Screen 1". Figure 5 shows that the screen data for each screen from "Screen 1" to "Screen 13" is saved in association with the screen number, screen name, and saved date and time.

Figure 6 is a diagram for explaining the difference information managed by the difference information management unit 13 in the monitoring screen creation support device 2 according to the first embodiment. The screen number, difference number, coordinate position, and difference information are stored in the difference information storage unit 27 of the difference information management unit 13, with the screen number, difference number, coordinate position, and difference information being linked to each other. If the difference information is difference information indicating that the attributes of a part have been updated, the coordinate position is represented by the coordinates of the part whose attributes have been updated. If the difference information is difference information indicating that the attributes of a symbol have been updated, the coordinate position is represented by the coordinates of the symbol whose attributes have been updated.

For example, the first line in FIG. 6 shows difference information when an update is made to change the position of a part, and the screen number, difference number, and coordinate position associated with the difference information. Here, the coordinates on the monitoring screen 41 are the XY coordinates. The coordinate position "(100, 300) - (400, 500)" indicates that the part has been moved from the position X = 100, Y = 300 to the position X = 400, Y = 500. The part ID (identifier) is identification information unique to each part. The difference information "Part Movement (Part ID 1) [(100, 300) - (400, 500)]" indicates that the part with part ID "1" has been moved from the position X = 100, Y = 300 to the position X = 400, Y = 500.

In the example shown in FIG. 6, the difference information shown on the first line and the difference information shown on the second line both have the screen number "1", but the difference number on the first line is "1" and the difference number on the second line is "2". In this way, when the screen numbers are the same but the difference numbers are different, this indicates that the difference information was saved on different dates and times for the same monitoring screen 41. Also, in the example shown in FIG. 6, the difference information shown on the first line and the difference information shown on the third line both have the difference number "1", but the screen number on the first line is "1" and the screen number on the third line is "2". In this way, when the difference numbers are the same but the screen numbers are different, this indicates that the difference information was saved on the same date and time for different monitoring screens 41.

Next, the procedure of operation by the monitoring screen creation support system 1 will be described. FIG. 7 is a flowchart showing an example of the procedure of operation by the monitoring screen creation support system 1 according to the first embodiment. The procedure shown in FIG. 7 is the procedure of operation of the monitoring screen creation support system 1 when a request for display of the monitoring screen 41 is made by the terminal device 3. It is assumed that the screen data of the monitoring screen 41 requested to be displayed is stored in the screen data storage unit 32.

In step S1, the monitoring screen creation support device 2 receives a display request for the monitoring screen 41 via the input unit 10 and the input information analysis unit 11. Upon receiving the display request for the monitoring screen 41, in step S2, the screen editing unit 12 reads out screen data for the monitoring screen 41 specified by the display request from the screen data management unit 14. The attribute editing unit 20 instructs the screen data management unit 14 to read out the screen data. In accordance with the instruction, the screen data acquisition unit 31 acquires the screen data for the specified monitoring screen 41 from the screen data storage unit 32 and outputs the acquired screen data to the attribute editing unit 20. As a result, the screen editing unit 12 reads out the screen data for the specified monitoring screen 41 from the screen data management unit 14.

The attribute editing unit 20 outputs the read screen data to the output unit 15. The output unit 15 transmits the screen data to the terminal device 3. In step S3, the terminal device 3 displays the monitoring screen 41 on the editing screen 40 based on the received screen data.

In step S4, the screen editing unit 12 determines whether or not an operation to edit the monitoring screen 41 has been performed on the terminal device 3. If an operation to edit the monitoring screen 41 has been performed (step S4, Yes), in step S5, the screen editing unit 12 executes an editing process for the monitoring screen 41 in accordance with the operation. On the other hand, if an operation to edit the monitoring screen 41 has not been performed (step S4, No), the monitoring screen creation support system 1 proceeds to step S12.

After completing step S5, in step S6, the monitoring screen creation support device 2 determines whether or not there has been a request to save the edited monitoring screen 41 via the input information analysis unit 11. If there has been no request to save the edited monitoring screen 41 (step S6, No), the attribute editing unit 20 outputs the edited screen data to the difference information management unit 13. In step S7, the data accumulation unit 25 of the difference information management unit 13 accumulates the edited screen data. The data accumulation unit 25 also acquires the screen data at the start of editing, i.e., the screen data before editing, from the attribute editing unit 20. After completing step S7, the monitoring screen creation support system 1 returns the procedure to step S4.

On the other hand, if there is a request to save the edited monitoring screen 41 (step S6, Yes), the data accumulation unit 25 outputs the edited screen data and the screen data before editing to the difference analysis unit 26. In step S8, the difference analysis unit 26 analyzes the difference between the attributes shown in the edited screen data and the attributes shown in the screen data before editing. The difference analysis unit 26 finds the difference between the attributes before and after the update for each component and each symbol shown on the monitoring screen 41.

The difference analysis unit 26 outputs difference information indicating the obtained difference to the difference information storage unit 27. In step S9, the difference information management unit 13 stores the difference information in the difference information storage unit 27, thereby preserving the difference information.

Furthermore, in response to a request to save the edited monitoring screen 41, the attribute editing unit 20 outputs the edited screen data to the screen data management unit 14. The screen data acquisition unit 31 outputs the screen data for the edited monitoring screen to the screen data storage unit 32. In step S10, the screen data management unit 14 saves the screen data by storing the screen data in the screen data storage unit 32.

After completing step S10, in step S11, the screen editing unit 12 determines whether or not an operation to close the monitoring screen 41 has been performed on the terminal device 3. If an operation to close the monitoring screen 41 has not been performed (step S11, No), the monitoring screen creation support system 1 returns the procedure to step S4. On the other hand, if an operation to close the monitoring screen 41 has been performed (step S11, Yes), the monitoring screen creation support system 1 ends the operation according to the procedure shown in FIG. 7.

In step S12, the monitoring screen creation support device 2 determines whether or not there has been a request to display the difference information through the input information analysis unit 11. If there has been no request to display the difference information (step S12, No), the monitoring screen creation support system 1 proceeds to step S11.

On the other hand, if there is a request to display the difference information (step S12, Yes), the difference information management unit 13 performs processing to display the difference information and the difference location on the terminal device 3. The difference information management unit 13 outputs the difference display information to the output unit 15. The output unit 15 transmits the difference display information to the terminal device 3. In step S13, the terminal device 3 displays the difference information on the editing screen 40 based on the received difference display information. The terminal device 3 also displays the difference location on the editing screen 40 based on the received difference display information. The difference information management unit 13 performs processing to display the update history on the terminal device 3. The output unit 15 transmits the update history information to the terminal device 3. The terminal device 3 displays the update history on the editing screen 40 based on the received update history information. After completing step S13, the monitoring screen creation support system 1 returns the procedure to step S4.

Next, the operation of displaying difference information will be described in detail. FIG. 8 is a flowchart showing an example of the procedure of the operation of the monitoring screen creation support system 1 according to the first embodiment to display difference information. The procedure shown in FIG. 8 is the procedure of the operation of the monitoring screen creation support system 1 from when a display request for difference information is made by the terminal device 3 to when the difference information is displayed, and corresponds to step S13 shown in FIG. 7.

In step S21, the monitoring screen creation support device 2 receives a display request for differential information via the input unit 10 and the input information analysis unit 11. In step S22, the differential information acquisition unit 28 of the differential information management unit 13 reads out the differential information from the differential information storage unit 27. The differential information acquisition unit 28 outputs the differential information acquired from the differential information storage unit 27 to the differential information formatting unit 29.

In step S23, the difference information formatting unit 29 formats the difference information. The difference information formatting unit 29 formats the difference information for display on the editing screen 40. The difference information formatting unit 29 formats the difference information illustrated in FIG. 6 into difference information whose content is to be displayed in the speech bubble 48 on the editing screen 40. The difference information formatting unit 29 also generates information on the difference location to be displayed on the editing screen based on the coordinate position information linked to the difference information as shown in FIG. 6. Furthermore, the difference information formatting unit 29 generates an update history to be displayed in the update history display area 45 shown in FIG. 4 based on the difference information illustrated in FIG. 6 and the information linked to the difference information in FIG. 6.

The difference information formatting unit 29 outputs the formatted difference information, information on the difference locations, and the update history to the difference display unit 30. The difference display unit 30 performs processing for displaying the difference locations, processing for displaying the formatted difference information, and processing for displaying the update history. The difference display unit 30 outputs the difference display information and the update history information to the output unit 15. The output unit 15 outputs the difference display information and the update history information to the terminal device 3.

In step S24, the terminal device 3 displays the update history in the update history display area 45 based on the received update history information. When the worker clicks on one of the rows for each difference number in the displayed update history, in step S25, the terminal device 3 accepts the selection of difference information.

In step S26, the terminal device 3 displays the difference location and the difference information. As shown in FIG. 4, the terminal device 3 displays the difference location by displaying an object 46 surrounding the symbol 44, which is the difference location. When the difference information is difference information about a difference in the attributes of the symbol 44, the terminal device 3 displays a mark 47 indicating that a difference has occurred in the attributes of the symbol 44 near the object 46. When the mark 47 is clicked, the terminal device 3 displays a speech bubble 48 displaying an overview of the difference information about the symbol 44. Furthermore, when the character string "display details" displayed in the speech bubble 48 is clicked, the terminal device 3 displays a window showing detailed information about the difference information. With the above, the monitoring screen creation support system 1 ends the operation according to the procedure shown in FIG. 8.

According to the first embodiment, the monitoring screen creation support system 1 stores difference information indicating the difference between the attributes before and after the update, and displays the difference location, which is the position of the symbol whose attribute has been updated, and the difference information on the editing screen 40. The monitoring screen creation support system 1 can easily check the attribute difference between before and after the update and the location where the attribute has been updated for the attribute update of a part or symbol in a past editing work during the editing work. The worker can perform the editing work while understanding the change in the attribute from the past due to the update. The worker can perform the editing work efficiently because the complicated work of checking the change in the attribute from the past due to the update is not required. As described above, the monitoring screen creation support system 1 has the effect of making the editing work of the monitoring screen 41 more efficient.

Embodiment 2.
In the second embodiment, a modified example of displaying the difference part on the editing screen 40 will be described. In the second embodiment, the same components as those in the first embodiment are given the same reference numerals, and the configuration different from the first embodiment will be mainly described.

Fig. 9 is a diagram showing an example of the configuration of a difference information management unit 13A provided in the monitoring screen creation support device 2 according to the second embodiment. The difference information management unit 13A has the same configuration as the difference information management unit 13 shown in Fig. 2, to which a position calculation unit 33 has been added. By including the position calculation unit 33, the difference information management unit 13A displays the difference portion in an enlarged manner on the editing screen 40.

The difference information formatting unit 29 outputs the formatted difference information, information on the difference location, which is information indicating the position of the symbol whose attribute has been updated, and the update history to the position calculation unit 33. The position calculation unit 33 outputs the formatted difference information and the update history to the difference display unit 30.

The difference information management unit 13A is capable of switching on and off a focus mode in which the difference parts are enlarged and displayed. When the focus mode is on, the position calculation unit 33 processes the information on the difference parts to enlarge and display the difference parts. The position calculation unit 33 outputs the information on the corrected difference parts to the difference display unit 30. The difference display unit 30 enlarges and displays the difference parts on the editing screen 40 according to the information on the corrected difference parts.

Fig. 10 is a diagram showing an example of an editing screen 40 displayed by the monitoring screen creation support system 1 according to the second embodiment. Fig. 10 shows an example of the editing screen 40 when the focus mode is on. In the editing screen 40 shown in Fig. 10, the difference part, which is a symbol 52 surrounded by objects 46, is placed near the center of the editing screen 40 and is displayed in an enlarged form. The difference part and its surrounding area are displayed in an enlarged form on the monitoring screen 41 of the editing screen 40. That is, a part of the equipment that is the subject of monitoring control is displayed in an enlarged form on the monitoring screen 41. In addition, a display area 51 is provided within the monitoring screen 41 to indicate the position of the part of the entire equipment that is being enlarged and displayed on the monitoring screen 41.

The editing screen 40 is provided with a slide button 50 for switching the focus mode on and off. By operating the slide button 50, the worker can switch the display of the difference parts between an enlarged display of the difference parts and a normal display that displays the difference parts within the entire facility. The enlarged display of the difference parts allows the worker to easily confirm the difference parts. By checking the display in the display area 51 together with the enlarged display of the difference parts, the worker can easily grasp the position of the difference parts within the entire facility.

Next, the operation of the monitoring screen creation support system 1 to display difference information will be described. FIG. 11 is a flowchart showing an example of the procedure of the operation of the monitoring screen creation support system 1 according to the second embodiment to display difference information. The procedure shown in FIG. 11 is the procedure of the operation of the monitoring screen creation support system 1 from when a display request for difference information is made by the terminal device 3 to when the difference information is displayed.

Steps S21 to S25 in FIG. 11 are the same as steps S21 to S25 in FIG. 8. In FIG. 11, after completing step S25, the monitoring screen creation support system 1 advances the procedure to step S31.

The terminal device 3 sends a focus mode switching request to the monitoring screen creation support device 2 in accordance with the operation of the slide button 50. The input unit 10 and input information analysis unit 11 of the monitoring screen creation support device 2 accept the focus mode switching request. The difference information management unit 13A switches the focus mode on and off based on the focus mode switching request using the position calculation unit 33.

In step S31, the position calculation unit 33 determines whether or not the focus mode is on. If the focus mode is on (step S31, Yes), the position calculation unit 33 processes the information on the difference part to enlarge and display the difference part. The difference display unit 30 performs processing to display the enlarged difference part, processing to display the shaped difference information, and processing to display the update history. Thereafter, in step S32, the terminal device 3 enlarges and displays the difference part, and displays the difference information. Note that the display of the update history and the display of the difference information are the same as in the case of embodiment 1.

On the other hand, if the focus mode is not on (step S31, No), that is, if the focus mode is off, the position calculation unit 33 does not enlarge the difference area, and outputs information about the difference area to the difference display unit 30. Then, in step S26, the terminal device 3 displays the difference area and the difference information, as in the case of embodiment 1. With the above, the monitoring screen creation support system 1 ends the operation according to the procedure shown in FIG. 11.

According to the second embodiment, the monitoring screen creation support system 1 can enlarge and display the difference areas. This allows the worker to easily check the difference areas.

Embodiment 3.
In the third embodiment, a modified example of displaying the update history on the editing screen 40 will be described. In the third embodiment, the same components as those in the first or second embodiment are denoted by the same reference numerals, and the configuration different from the first or second embodiment will be mainly described.

The difference information management unit 13 provided in the monitoring screen creation support device 2 according to the third embodiment has a configuration similar to that of the difference information management unit 13 shown in FIG. 2. In the third embodiment, the difference information management unit 13 displays the update history by grouping it according to at least one of the symbol, the part, and the number of times that the attribute of the symbol has been updated. The number of times that the attribute of the symbol has been updated includes the number of times that the attribute of the part that constitutes the symbol has been updated, and the number of times that the attribute of the symbol has been configured.

The difference information formatting unit 29 generates the grouped update history. The difference display unit 30 receives the grouped update history from the difference information formatting unit 29 and displays the update history by grouping it based on at least one of the symbol, the parts that are the figures that make up the symbol, and the number of times attributes of the symbol have been updated.

Fig. 12 is a diagram showing an example of an editing screen 40 displayed by the monitoring screen creation support system 1 according to the third embodiment. In the example shown in Fig. 12, the update history display area 60 that displays the update history displays the update history grouped by device for multiple devices installed in the equipment that is the subject of monitoring and control. That is, the update history display area 60 displays the update history grouped by symbol. In Fig. 12, "Valve 1", "Valve 2", "Valve 3", "Aquarium 1", and "Aquarium 2" are each devices installed in the equipment.

In Figure 12, the update history is divided into groups: "Valve 1," "Valve 2," "Valve 3," "Aquarium 1," and "Aquarium 2." In Figure 12, for "Valve 1," the update history for each difference number is displayed expanded. For each of "Valve 2," "Valve 3," "Aquarium 1," and "Aquarium 2," only the device name, which is the group name, is displayed, and the update history display is in a collapsed state. The update history can be expanded or collapsed for each group by clicking the device name. The update history within the group is displayed in chronological order.

The update history display area 60 also has a selection field 61 for selecting the grouping criteria. As shown in FIG. 12, the display of "equipment" in the selection field 61 indicates that equipment is selected as the item that is the grouping criteria. Clicking on the selection field 61 displays a list of multiple item names that can be selected as the grouping criteria. In addition to "equipment", the multiple item names include "parts", "number of updates", and "chronological order". When "parts" is selected, the update history is displayed in groups by part. When "number of updates" is selected, the update history is displayed in groups by the number of updates of the attributes of each equipment indicated by a symbol. When "chronological order" is selected, the grouping is canceled, and the update history of all equipment of the facility is displayed in chronological order, as in the case of the update history display area 45 shown in FIG. 4. Note that the items used as the grouping criteria are not limited to symbols, parts, and number of updates. Any item can be set as the grouping criteria.

The procedure for the operation of displaying difference information in the third embodiment is the same as the procedure shown in FIG. 8. In the third embodiment, a process for grouping and displaying the update history is added to the process for displaying the update history in the difference information formatting unit 29.

According to the third embodiment, the monitoring screen creation support system 1 can group and display the update history. This allows the worker to easily check the difference information and the difference locations.

Embodiment 4.
In the fourth embodiment, a modified example of displaying the update history on the editing screen 40 will be described. In the fourth embodiment, the same components as those in the first to third embodiments are given the same reference numerals, and the configurations different from those in the first to third embodiments will be mainly described.

The difference information management unit 13 provided in the monitoring screen creation support device 2 according to the fourth embodiment has a configuration similar to that of the difference information management unit 13 shown in FIG. 2. In the fourth embodiment, the difference information management unit 13 displays the shape of the symbol before the attribute is updated and the shape of the symbol after the attribute is updated, superimposed on each other. Also, in the fourth embodiment, the difference information management unit 13 displays a list of attributes before and after the update for attributes assigned to the symbol. Note that for symbols that have been updated multiple times in the past, the "updated attribute" in the fourth embodiment refers to the updated attribute when the symbol was last updated. In other words, the "updated attribute" refers to the current attribute.

The difference display unit 30 performs processing to display the shape of the symbol before the attributes are updated and the shape of the symbol after the attributes are updated, superimposed on each other. The difference display unit 30 also performs processing to display a list of the attributes assigned to the symbol before and after the update.

Figure 13 is a diagram showing an example of an editing screen 40 displayed by the monitoring screen creation support system 1 according to the fourth embodiment. A mark 47 indicating that a difference has occurred in the attributes of a symbol 44 is displayed on the editing screen 40 shown in Figure 13. When the mark 47 is clicked, a speech bubble 70 displaying an overview of the difference information for the symbol 44 is displayed on the editing screen 40. A graphic difference image and a list of attributes are displayed in the speech bubble 70 as an overview of the difference information.

In FIG. 13, the graphical difference image is an image shown with the words "graphic difference" attached. The graphical difference image is a superimposition of the shape of the symbol before the attributes are updated and the shape of the symbol after the attributes are updated. In FIG. 13, the white parts of the graphical difference image and the hatched parts are displayed in different colors.

The shape of the white parts in the graphic difference image represents the shape of the symbol before the attributes were updated. The shape of the white parts combined with the hatched parts in the graphic difference image represents the shape of the symbol after the attributes have been updated. In other words, the hatched parts represent the difference between the shape of the symbol before the attributes were updated and the shape of the symbol after the attributes have been updated. From the graphic difference image, the worker can easily confirm how the shape of the symbol has changed.

In FIG. 13, the attribute list is a table labeled with the words "attribute difference." The attribute list is a list of attributes before and after the update. In the attribute list, for symbols marked with mark 47, the attributes before the update and the attributes after the update are displayed side by side. The "Current" column in the attribute list shown in FIG. 13 represents the attributes after the update, i.e., the current attributes. The "Original" column in the attribute list shown in FIG. 13 represents the attributes before the update. From the attribute list, the worker can easily check how the attributes of the symbol have been changed.

In the attribute list shown in FIG. 13, lines marked with halftone tones represent attributes that have been changed by the update. In the attribute list shown in FIG. 13, lines marked with white tones represent attributes that have not been changed by the update. Lines marked with halftone tones are displayed in a different color from the white lines so that they stand out more than the white lines. In this way, the difference display unit 30 highlights the updated attributes in the attribute list.

In this way, by highlighting the updated attributes in the attribute list, the worker can easily check the attributes that have been changed due to the update in the attribute list. Note that the highlighting is not limited to making the color of the row for the updated attribute different from the color of the row for the non-updated attribute. The highlighting may be, for example, making the text color for the updated attribute different from the text color for the non-updated attribute. Also, the highlighting is not limited to making the color different, and may be any text color that allows the updated attribute to be easily recognized. The highlighting may be blinking or enlarged, or a mark indicating that it is an updated attribute may be displayed.

Next, the operation of the monitoring screen creation support system 1 to display difference information will be described. FIG. 14 is a flowchart showing an example of the procedure of the operation of the monitoring screen creation support system 1 according to the fourth embodiment to display difference information. The procedure shown in FIG. 14 is the procedure of the operation of the monitoring screen creation support system 1 from when a display request for difference information is made by the terminal device 3 to when the difference information is displayed.

Steps S21 to S25 in FIG. 14 are the same as steps S21 to S25 in FIG. 8. In FIG. 14, after completing step S25, the monitoring screen creation support system 1 advances the procedure to step S41.

The difference display unit 30 acquires difference information from the difference information formatting unit 29. For symbols that have been updated multiple times in the past, the difference display unit 30 acquires difference information for each update from the difference information formatting unit 29. Based on the acquired difference information, the difference display unit 30 performs processing for displaying a graphic difference image and a list of attributes. The difference display unit 30 outputs difference display information to the output unit 15, which is information for displaying the difference locations, the graphic difference image and attribute list that are the difference information, and the update history on the editing screen 40. The output unit 15 outputs the difference display information to the terminal device 3.

In step S41, the terminal device 3 displays the difference location, a graphic difference image, and a list of attributes. When the mark 47 is clicked, the terminal device 3 displays a speech bubble 70 that displays the graphic difference image and the list of attributes. With this, the monitoring screen creation support system 1 ends the operation according to the procedure shown in FIG. 14.

According to the fourth embodiment, the monitoring screen creation support system 1 displays a graphic difference image in which the shape of the symbol before the attribute is updated and the shape of the symbol after the attribute is updated are superimposed on each other. The monitoring screen creation support system 1 also displays an attribute list that is a list of the attributes assigned to the symbol before and after the update. This allows the worker to easily check how the attributes of the symbol have been changed.

In the above explanation, the monitoring screen creation support system 1 is described as displaying both a graphic difference image and an attribute list, but it is sufficient if it displays at least one of a graphic difference image and an attribute list. By having the monitoring screen creation support system 1 display at least one of a graphic difference image and an attribute list, the worker can easily check how the attributes of the symbol have been changed.
