[Technical Field]

[0001] The present disclosure relates to a monitoring device, a monitoring system, a monitoring method, and a monitoring program that monitor and control a monitoring target using a monitoring screen. [Background technology]

[0002] Conventionally, monitoring devices that monitor water treatment facilities are known. These monitoring devices create a monitoring screen that shows the status of multiple pieces of equipment to be monitored and present it to an operator via a display device. By checking the monitoring screen, the operator can know the status of the equipment even if they are not actually at the monitored facility.

[0004] [Patent Document 1] JP 2022-68357 A (Page 9, 0045) Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, operators monitor and control the monitored objects by checking the monitoring screen, but the arrangement of components on the screen can sometimes make the operation inconvenient. These components refer to panels and other components placed on the monitoring screen for instructing operations, which can be operated to operate equipment or display new information, and are used by monitors to perform monitoring and control tasks. Operators may experience operational inconveniences, such as an inexperienced operator feeling that there are not enough components, or an experienced operator feeling that unused components are redundant. Conventional technologies have not been able to provide a monitoring screen that operators can operate comfortably.

[0006] The present disclosure has been made to solve the above-mentioned problems, and aims to present an appropriate monitoring screen to the operator by assisting the operator in creating a screen that is comfortable for the operator to operate. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the monitoring device of the present disclosure includes an acquisition unit that acquires monitoring screen information including proficiency levels linked to the created monitoring screen, a judgment unit that judges whether or not a component needs to be placed on the monitoring screen to be evaluated from the monitoring screen information acquired by the acquisition unit, and a generation unit that generates an evaluation image that indicates whether or not a component needs to be placed on the monitoring screen to be evaluated. [Effects of the Invention]

[0008] The monitoring device according to the present disclosure can present the necessity of placement of components on the monitoring screen based on monitoring screen information including proficiency levels linked to the monitoring screen, and supports the creation of a screen that allows the operator to operate comfortably. This makes it possible to present an appropriate monitoring screen to the operator, leading to improved work efficiency in monitoring and control. [Brief explanation of the drawings]

[0010] A monitoring device, a monitoring system, a monitoring method, and a monitoring program according to embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the present disclosure is not limited to each embodiment, and each embodiment can be combined or modified as appropriate. Furthermore, when multiple drawings have the same configuration, the description thereof will be omitted.

[0011] Embodiment 1 1 shows the configuration of a monitoring system 1 according to a first embodiment. The monitoring system 1 includes a monitoring device 20, a terminal device 10, and a storage device 15. The monitoring system 1 is connected to a plurality of facilities to be monitored via a communication device 32. The devices and the facilities to be monitored are connected and capable of communicating with each other via a network 16. The network 16 is, for example, a WAN (Wide Area Network) such as the Internet.

[0012] The terminal device 10 is a device that displays a monitoring screen so that an operator can check the status of a monitored object and perform operations. The terminal device 10 comprises a communication unit 11, a processing unit 12, a display unit 13, and an input unit 14. The communication unit 11 is connected and capable of communicating via a network 16 to send and receive information. The display unit 13 displays the monitoring screen so that the operator can check it, and the input unit 14 accepts operations on the monitoring screen from the operator. The processing unit 12 controls the operations of the communication unit 11, the display unit 13, and the input unit 14.

[0013] The terminal device 10 is, for example, a mobile device such as a smartphone, a tablet, or a notebook personal computer, or a desktop computer. The display unit 13 is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display. The input unit 14 includes, for example, a keyboard, a mouse, a keypad, or a touch panel.

[0014] The storage device 15 stores information used in the monitoring system 1, and the information includes monitoring screen information, information on parts arranged on the monitoring screen, and information on the operation history of the monitoring screen.

[0015] The monitoring device 20 is configured, for example, by one or more cloud servers. A cloud server is a server built in a cloud environment that includes computer resources provided by a cloud service platform. Note that the monitoring device 20 may be a server other than a cloud server, for example, an on-premise server.

[0016] The terminal device 10 and storage device 15 in Figure 1 are connected outside the monitoring device 20 via a network 16, but if similar operation can be achieved, the monitoring device 20 may be configured as a single monitoring system that includes the terminal device 10 and storage device 15.

[0017] The facilities to be monitored are, for example, water treatment facilities, railway facilities, or plants, which are made up of a combination of multiple pieces of equipment that require monitoring and are controlled by multiple means. Figure 1 illustrates the operation of water treatment facilities, with Water Treatment Plant A 30a and Water Treatment Plant B 30b as examples. Each piece of equipment 31 to be controlled is, for example, a pool that stores water, a sluice gate that releases water, or a pump that draws water. Each piece of equipment 31 is also equipped with sensors to monitor its condition, such as a water level gauge, a pressure gauge, a temperature sensor, a flow rate sensor, or a position sensor.

[0018] Each facility to be monitored is equipped with a communication device 32 and a control device 33. The communication device 32 is connected and capable of communicating via the network 16 to send and receive information. The control device 33 acquires information from sensors installed in each piece of equipment 31 and performs necessary control in accordance with instructions from an operator. Note that if there is a facility environment for the monitoring target that can be monitored on-premise, the monitoring device 20 may acquire information from the control device 33 via the network 16.

[0019] The monitoring device 20 is a computer installed in a facility managed by an operator who monitors and controls the monitored objects. The monitoring device 20 is a device that allows the operator to monitor and control multiple facilities that are monitored, and has the function of visualizing facility information as a monitoring image and the function of controlling equipment in accordance with parts operated by the operator.

[0020] 2 is a diagram showing the configuration of the monitoring device 20. The monitoring device 20 includes an acquisition unit 21, a determination unit 22, an output unit 23, and a generation unit 24. The acquisition unit 21 and the output unit 23 are connected and capable of communicating via the network 16, with the acquisition unit 21 receiving information and the output unit 23 transmitting information. The determination unit 22 determines the information that needs to be output based on the operation performed by the operator on the terminal device 10. The generation unit 24 generates the necessary information based on the determination of the determination unit 22.

[0021] As an example of the operation of the monitoring device 20, for example, when an operator wants to check the water volume at Water Treatment Plant A, the monitoring device 20 receives instruction information indicating that Water Treatment Plant A has been selected by operating the terminal device 10. To check the water volume, information is acquired from the water level meter of facility 31a of Water Treatment Plant A 30a. A monitoring screen is generated based on the acquired water volume information, and the information is output to the terminal device 10.

[0022] If the operator checks the generated monitoring screen and determines that control of water discharge is necessary, the operator operates the parts that control water discharge, which are arranged on the monitoring screen of the terminal device 10. Based on the operation received from the terminal device 10, the monitoring device 20 notifies the control device 33a of the A water treatment plant 30a of an instruction to open the sluice gates to discharge water. Through a series of operations of the monitoring device 20, the operator can efficiently manage multiple facilities to be monitored by checking the monitoring screen and operating the parts to give instructions.

[0023] In the monitoring device 20, the operator can create the monitoring screen himself / herself in order to create a monitoring screen suitable for the operator. Note that the person who creates the monitoring screen is not limited to the operator, and the creator and the operator may be the same person or different people, and will be referred to as the creator in the examples. The monitoring device 20 indicates the appropriateness of the arrangement of parts for operation arranged on the monitoring screen during creation.

[0024] The following describes the operation of indicating whether the placement of placed parts is appropriate in the monitoring device 20 when creating a monitoring screen. The appropriateness of the placement is determined based on the proficiency level set for the monitoring screen, from the monitoring screen to be created, which is the evaluation target, and the monitoring screen that has already been created.

[0025] FIG. 3 is an example of a monitoring screen displayed on the terminal device 10 during its creation, which is a screen for monitoring the water volume at Water Treatment Plant A. The creator operates the terminal device 10 to create the monitoring screen. Each monitoring screen is set with a proficiency level appropriate for the operator to operate that monitoring screen, and the creator also sets the proficiency level when creating the monitoring screen. The monitoring screen in FIG. 3 is for intermediate users. Note that the proficiency levels are divided into beginner, intermediate, and advanced in the example, but they may be set to three or more levels, or may be set as follows, or may be more finely divided and numerically set.

[0026] Next, the configuration for creating a monitoring screen will be described. Monitoring screen 40 includes parts 41A, 41B, an image 42, and a part candidate board 45. The operator can operate the monitoring screen by selecting part 41A. For example, selecting a part labeled "control management" issues an instruction to switch equipment on and off, such as opening a sluice gate to release excess water. Placement candidate parts, with these operations and on-screen display formats pre-set, are placed on part candidate board 45, and when creating a monitoring screen, part 41B is selected and placed anywhere on monitoring screen 40. Once set, placement candidate parts can be used not only when creating a specific monitoring screen, but also when creating different monitoring screens.

[0027] Screen 42 is an image showing the state of the monitored object, and in Fig. 3 it shows the change in water volume over time. Note that screen 42 is not limited to displaying a graph showing measured values, and may also display images or videos taken of the site in real time by a camera. Furthermore, the number of images displayed is not limited to one, and two or more images may be displayed.

[0028] 4 shows monitoring screen information 50, which shows information about created monitoring screens in a data table. The monitoring screen information 50 includes a screen identification symbol 52 that identifies each monitoring screen, a monitoring target symbol 53 that identifies the monitoring target, a type symbol 54 that identifies the monitoring purpose of the monitoring screen, and a screen proficiency level 55 that indicates the proficiency level suitable for operating the monitoring screen.

[0029] 5 shows part information 60, which is a data table showing information about parts placed on a created monitoring screen. The part information 60 includes a screen identification symbol 52 that identifies the monitoring screen on which the part is placed, a part symbol 63 that identifies the part, and an importance 64 that indicates the importance of placement set individually for the part. The importance indicated by the importance 64 is a part that is absolutely necessary for monitoring work and whose omission in placement could cause disruption to normal operation, such as a part that issues an emergency shutdown command for equipment.

[0030] When the creator creates a monitoring screen, the acquisition unit 21 acquires monitoring screen information 50 from the storage device 15. Furthermore, when the creator performs an operation related to the placement of a component on the monitoring screen, the acquisition unit 21 acquires component information 60 linked to the monitoring screen information 50. The determination unit 22 compares the information of the monitoring screen being created with the monitoring screen information 50, which is information of the monitoring screen that has already been created, determines whether placement of the placed component is necessary, and calculates evaluation result information.

[0031] Next, the method for determining whether a part needs to be placed in the determination unit 22 will be described. When the creator of a monitoring screen deletes a part from its placement, the determination unit 22 determines whether a part is necessary based on the evaluation result information 70. First, the information on the monitoring screen being created is compared with the monitoring screen information 50, which is information on monitoring screens that have already been created, and monitoring screens created with the same type symbol and proficiency level are extracted. Extraction based on proficiency level allows for identification of parts used in monitoring screens for similar purposes by people with the same level of operational understanding. If a part identical to the deleted part exists in the extracted monitoring screen and is used a predetermined number of times or more, the part is determined to be a necessary part that requires placement. The number of times indicates the frequency of placement, and by setting this number, parts that are unlikely to be used can be omitted. In addition, for parts below the number of times, the individually set importance of the part is referenced, and parts with a high importance are again determined to be necessary parts. This prevents missing parts, which would disrupt normal operation if omitted.

[0032] On the other hand, when the creator of the monitoring screen places a new part, the judgment unit 22 judges whether the part is unnecessary based on the evaluation result information 70. As with the operation of necessary parts, if the placed part does not exist in the monitoring screen extracted based on the proficiency level, or if it exists but is used in a number less than a predetermined reference number, the part is judged to be an unnecessary part that does not need to be placed. By setting a reference number in the same way as for necessary parts, parts that are unlikely to be used can be omitted.

[0033] 6 shows evaluation result information 70, which is a data table that combines monitoring screen information 50, which is information about the monitoring screen being created and the monitoring screen that has already been created, and component information 60 for the relevant component, through a series of operations. The evaluation result information 70 includes a generated screen proficiency level 72 indicating the proficiency level of the monitoring screen being created, a generated screen type symbol 73 that identifies the monitoring purpose of the monitoring screen being created, a screen identification symbol 52, a type symbol 54, a screen proficiency level 55, a component symbol 63, and an importance level 64. In addition, it is assumed that the criteria for the number of unnecessary components are one or less, and that the number of necessary components is three or more.

[0034] In Figure 6, part number 1 is determined to be a necessary part because there is a symbol for importance. Part number 2 is determined to be a necessary part because there are three usage records for a reference number of 3 or more. Part number 3 is determined to be an unnecessary part because there is one usage record for a reference number of 1 or less.

[0035] The determination of the necessity of deployment by the determination unit 22 may be made using artificial intelligence (AI). The determination of the necessity of deployment by AI uses a learned model that has learned monitoring screen information of a monitoring screen that has already been created.

[0036] Using AI, the system extracts part placement trends on the created monitoring screen for the relevant proficiency level from the trained model. By using the results extracted by AI, it is possible to incorporate subtle trends that cannot be extracted using regular conditions, thereby improving the effectiveness of determining whether placement is necessary.

[0037] The calculated determination of whether placement is necessary or not is shown on the monitoring screen of the evaluation target and displayed on the terminal device 10. The generation unit 24 generates an evaluation image indicating whether placement is necessary or not on the monitoring screen of the evaluation target, and outputs it from the output unit 23 to the terminal device 10. FIGS. 7 and 8 are examples of evaluation images displayed on the terminal device 10.

[0038] Figure 7 shows an evaluation screen that calls attention when an unnecessary part is placed on the monitoring screen of the evaluation target. When an unnecessary part 41C is placed, the part 41C is displayed in a different color so that it can be distinguished from other parts. In addition, on the monitoring screen of the same expert on the screen, a screen 46A indicating that the part is not used is displayed on the monitoring screen. This makes it possible to visually inform the creator that the part is unnecessary.

[0039] FIG. 8 is an evaluation screen showing an example of a monitoring screen displayed in addition to FIG. 7. FIG. 8 is displayed by switching the screen from FIG. 7. By showing screen 46B, which shows a created monitoring screen on which no components have been placed, as an example on the monitoring screen, the creator of the monitoring screen can improve his or her understanding. Note that the example monitoring screen is not limited to displaying one image, and multiple images may be displayed simultaneously.

[0040] 7 and 8 show examples of evaluation screens for unnecessary parts, but even in the case of necessary parts, the screen display indicating whether placement is necessary is performed in a similar manner. In this case, screen 45A indicates that the part is being used, and screen 46B shows the created monitoring screen in which the part is placed. Also, although the evaluation image is displayed when the part placement operation is performed, it may be displayed when the creator has completed placement of all parts. In this case, the creator will check the evaluation image and reconsider the placement of the parts.

[0041] Note that the numerical values ​​and symbols listed in the data table are merely examples, and are not limited to the examples provided that they are identifiable and capable of performing the actions described. Furthermore, the data extraction method may not only require exact matches with the same numerical values ​​and symbols, but also allow for arbitrary setting of extraction range conditions. By arbitrarily setting extraction range conditions, for example, in the case of type symbols, it is possible to utilize examples of component placement on monitoring screens with the same proficiency level and similar purposes. Monitoring the water volume of a dam is considered to be a monitoring screen with a similar monitoring purpose, and can be included in the extraction conditions.

[0042] Next, there will be shown the operational procedure of the process leading up to generation of an evaluation image for determining whether or not placement is necessary by monitoring device 20 in embodiment 1. Fig. 9 is a flowchart showing the operational procedure of the process for generating an evaluation image, Fig. 10 is a flowchart showing the operational procedure for determining whether or not placement of a part is necessary, and Fig. 11 is a flowchart showing the operational procedure for determining whether or not placement of a part is unnecessary.

[0043] In step S101, the monitoring device 20 arranges components in response to the creator's operation of the terminal device 10, and proceeds with the creation of the monitoring screen. In step S102, the acquisition unit 21 extracts monitoring screen information of the created monitoring screen from the storage device 15. In step S103, the determination unit 22 compares the monitoring screen to be evaluated with the monitoring screen information of the created monitoring screen. In step S104, the process proceeds to an operational procedure for determining whether or not components need to be arranged.

[0044] FIG. 10 shows the determination of necessary parts among the operational procedures for determining whether or not a part needs to be placed. In step S201, the determination unit 22 compares the monitoring screen information of the monitoring screen to be evaluated with that of the created monitoring screen. In step S202, the determination unit 22 extracts created monitoring screens with the same type symbol and proficiency level as the monitoring screen to be evaluated and the monitoring screen to be created. If there is no match in step S202, the process ends. If there is a match in step S202, the process proceeds to step S203. If there is a part that has been deleted by operating the monitoring device 20, and if that part exists in the monitoring screen information of the created monitoring screen in a number equal to or greater than a predetermined reference number, the process determines in step S205 that the part is a necessary part that needs to be placed. If there is no match in step S203, the process proceeds to step S204, referring to the importance of the part, and if there is a match, the process also returns to step S205. If there is no match in step S205, the process ends.

[0045] Of the operational procedures for determining whether a part needs to be placed, the determination of unnecessary parts is shown in Figure 11. In step S206, the same operation as in step S201 is performed, and in step S207, the same operation as in step S202 is performed. If there is no match in step S207, the process ends. If there is a match in step S202, the process proceeds to step S208, and if there is a part that was added by operating the monitoring device 20 and that part does not exist in the monitoring screen information of the created monitoring screen, or if the number of parts present is less than a preset reference number, the part is determined to be an unnecessary part whose placement is not necessary in step S209. Note that if there is no match in step S208, the process ends.

[0046] When each of the operational procedures for determining whether placement is necessary is completed, the process proceeds to step S105, where the generation unit 23 generates an evaluation image showing whether placement is necessary on the monitoring screen of the evaluation target, and the evaluation image is output from the output unit 23 to be displayed on the terminal device 10. After this, when it is confirmed in step S106 that the creation of the monitoring screen has been completed, the process ends, and if it is to continue, the process proceeds to step S101.

[0047] According to the first embodiment, it is possible to present the necessity of placement of components on a monitoring screen based on monitoring screen information including the proficiency level associated with the monitoring screen. For example, if a creator has determined that a component is unnecessary and not placed in the creation of a monitoring image for an intermediate user, and if there are many instances of placement of the component in other created monitoring screens with the same proficiency level, the system displays a message indicating that the component needs to be placed. On the other hand, even if the creator has placed a component that the creator determined is suitable for an intermediate user, if the placement of the component is limited in other created monitoring screens with the same proficiency level, the system displays a message indicating that the component placement is ineffective. The creator makes a final decision on whether to adopt the component based on the evaluation image, creates the monitoring screen, and provides the monitoring screen to the operator. This allows the operator to receive a monitoring screen that is comfortable to operate based on created monitoring screens with the same proficiency level, improving the efficiency of monitoring and control work.

[0048] Embodiment 2 The second embodiment differs from the first embodiment in that the monitoring screen to be evaluated by the determination unit 22 is not a monitoring screen being created but an already created monitoring screen, and the necessity of component placement is determined using operation history information of the already created monitoring screen. Furthermore, in the second embodiment, the necessity of component placement is determined not only between necessary components and unnecessary components but also between additional components.

[0049] The following describes the second embodiment with reference to the drawings. Note that the same reference numerals as those in the first embodiment indicate the same or corresponding parts, and descriptions of parts with the same configuration will be omitted. Also, descriptions of the same operational procedures will be omitted.

[0050] In the second embodiment, the determination of whether or not a part needs to be placed is made for a monitoring screen that has already been created. The monitoring screen to be evaluated is a screen for monitoring the water volume at Water Treatment Plant A, and the proficiency level suitable for operation is assumed to be intermediate. The monitoring screen has been used on-site in advance, and operated by an operator at terminal device 10, with a record of the operation history stored in storage device 15. Similarly, monitoring screens for each piece of equipment at Water Treatment Plant B have also been used, and a record of the operation history stored in storage device 15.

[0051] 12 shows operation history information 80, which shows information on the operation history of a created monitoring screen in a data table. The operation history information 80 includes an operation screen identification symbol 82 that identifies the operated monitoring screen, an operation screen type symbol 83 that identifies the monitoring purpose of the operated monitoring screen, an operation part symbol 84 that identifies the operated part, a timestamp 85 that records the date and time of the operation, an operator identification symbol 86 that identifies the operator who performed the operation, and an operator proficiency level 87 that indicates the operator's proficiency level.

[0052] When an operator operates the monitoring screen, the operator sets his / her own proficiency level in advance, and the operator proficiency level 86 is recorded in the operation history information 80 in association with the operator identification code 85. Note that the operator may set his / her own proficiency level by declaring and inputting the level himself / herself, or the level may be calculated from attribute information associated with the individual, such as age, career history, test score, and the amount of time spent operating the monitoring screen.

[0053] An operator who wishes to reconfigure a monitoring screen that has already been created operates the terminal device 10 to select the monitoring screen to be evaluated. The acquisition unit 21 acquires monitoring screen information 50 and operation history information 80 from the storage device 15. The acquisition unit 21 also acquires component information 60 linked to the monitoring screen information 50. The determination unit 22 compares the monitoring screen information 50 with the operation history information 80 to determine whether or not the component needs to be placed, and calculates evaluation result information.

[0054] FIG. 13 shows evaluation result information 90, which is a data table that combines monitoring screen information 50, operation history information 80, and component information 60 based on a series of operations. The evaluation result information 90 includes a component symbol 63, a monitoring screen symbol 52, a type symbol 54, a screen proficiency level 55, an operation screen type symbol 83, an operator proficiency level 87, an operation component symbol 84, an importance level 64, and an operation frequency 92 indicating the frequency of component operation based on the operation screen type symbol 83. The reference number for determining the operation frequency 92 is assumed to be two or more required and additional components, and one or less unnecessary components. The period for checking the operation frequency may be divided into arbitrary periods based on the record of the timestamp 85. By dividing the period for checking the operation frequency, the operation history of components not used in the trend at the time of evaluation can be omitted.

[0055] An example of a method for calculating evaluation result information is shown in Figure 13. Component symbol No. 1 is determined to be a necessary component because, in the operation history of the monitoring screen for the same type symbol and proficiency level, there is an operation frequency of two out of a reference number of two or more, and there is also a symbol for importance. Component symbol No. 3 is determined to be an unnecessary component because, in the operation history of the monitoring screen for the same type symbol and proficiency level, there is an operation frequency of one out of a reference number of one or less. Component symbol No. 5 is determined to be an additional component because, in the operation history of the monitoring screen for the same type symbol and proficiency level, there is an operation frequency of two out of a reference number of two or more, which is a part that does not exist on the monitoring screen being evaluated. For other component symbols, no determination is made as to whether they need to be placed.

[0056] FIG. 14 illustrates an example of an evaluation screen displayed on the monitoring screen of the evaluation target displayed on the terminal device 10 according to the second embodiment. The monitoring screen 47 includes a part 47A, a necessary part 48B, an unnecessary part 48C, an additional part 48D, and a screen 49. The part 48A is not a part for which the placement necessity is being determined, and no changes occur on the screen. The part 48B indicates a necessary part, the part 48C indicates an unnecessary part, and the part 48D is an additional part that is not present on the monitoring screen of the evaluation target and is determined to need to be newly added. Each part is displayed with a different colored periphery to distinguish it from the other parts. Similar to the screen 42, the image 48 indicates the status of the monitoring target. The monitoring screen 47 is a screen for monitoring the water volume of a water treatment plant A, and the proficiency level suitable for operation is shown as intermediate. Note that the part 47A, the necessary part 48B, the unnecessary part 48C, and the additional part 48D, for which the placement necessity is being determined, do not all need to be displayed simultaneously; only the relevant parts may be displayed.

[0057] Next, there will be shown the operational procedure of the process leading up to generation of an evaluation image for determining whether or not placement is necessary by monitoring device 20 in embodiment 2. Fig. 15 is a flowchart showing the operational procedure of the process for generating an evaluation image, and Fig. 16 is a flowchart showing the operational procedure for determining whether or not placement of a component is necessary.

[0058] In step S301, the monitoring device 20 selects a monitoring screen to be evaluated by the creator operating the terminal device 10. In step S302, the acquisition unit 21 extracts monitoring screen information and operation history information from the storage device 15. In step S303, the determination unit 22 compares the monitoring screen information with the operation history information. In step S304, the process proceeds to an operational procedure for determining whether or not component placement is necessary.

[0059] In step S401, the judgment unit 22 compares the monitoring screen information with the operation history information. In step S402, a search is made for a part that is the same as the part placed on the monitoring screen to be evaluated, with the same type symbol and operation history information of proficiency as the monitoring screen to be evaluated. If no match is found in step S402, the process proceeds to step S406. If a match is found in step S402, the process proceeds to step S403 to check whether the part has an operation frequency on the monitoring screen that is equal to or greater than a preset reference number. If a match is found in step S403, the process proceeds to step S405 to determine that the part is a necessary part that needs to be placed. If no match is found in step S403, the process proceeds to step S404, and if importance is set for the part, the process proceeds to step S405. If no match is found in step S404, the process proceeds to step S406.

[0060] In step S406, similarly to step S402, a search is made for a part identical to the part placed on the monitoring screen to be evaluated, with the same type symbol and operation history information of proficiency as the monitoring screen to be evaluated. If no match is found in step S406, the process proceeds to step S409. If a match is found in step S406, the process proceeds to step S407 to check whether the operation frequency of that part on the monitoring screen is below a preset reference number. If a match is found in step S407, the part in question is determined to be an unnecessary part whose placement is unnecessary in step S408. If no match is found in step S407, the process proceeds to step S409.

[0061] In step S409, operation history information with the same type symbol and proficiency as the monitoring screen to be evaluated is searched for. If no match is found in step S409, the process ends. If a match is found in step S409, in step S410, a search is made for parts that are not placed on the monitoring screen to be evaluated and that exist only on the monitoring screen with the same type symbol and proficiency operation history information. If no match is found in step S410, the process ends. If a match is found in step S410, in step S411, it is confirmed whether the part has an operation frequency on the monitoring screen that is equal to or greater than a preset reference number. If a match is found in step S411, in step S413, the part in question is determined to be an additional part that needs to be newly placed. If no match is found in step S411, the process proceeds to step S412, and if importance is set for the part, the process proceeds to step S413. If no match is found in step S412, the process ends.

[0062] According to the second embodiment, it is possible to present the necessity of placement of parts on a monitoring screen that has already been created, based on monitoring screen information including the proficiency level linked to the monitoring screen. The person who selects the monitoring screen to be evaluated makes a final decision on whether to adopt it, referring to the evaluation image. Furthermore, in the second embodiment, additional parts that need to be newly added are indicated in the placement necessity, thereby preventing omission of parts from being placed. This allows the operator to review the placement of parts on the monitoring screen that has already been created, and to be provided with a monitoring screen that allows for comfortable operation.
