Description

Technical Field

[0001] The present invention relates to an engineering device and an engineering method for performing various settings on devices constituting a facility monitoring system.

Background Art

[0002] Conventionally, an engineering device for creating setting data for operating a plurality of devices (such as a primary device and a secondary device, etc.) for monitoring or controlling devices installed in a facility has been known (see, for example, Patent Document 1). The engineering device creates setting data for each device and downloads (receives) the created setting data to each device, thereby constructing a facility monitoring system. Each device operates based on the setting data downloaded from the engineering device and monitors or controls other devices other than itself or one or more devices installed in the facility.

[0003] For example, a facility monitoring system includes a primary device, a secondary device connected under the primary device, and a device connected under the secondary device. The primary device monitors or controls the subordinate secondary device by operating based on the setting data downloaded from the engineering device. Also, the secondary device monitors or controls the subordinate device by operating based on the setting data downloaded from the engineering device.

[0004] When constructing a facility monitoring system, the engineering device operates in an engineering mode and, for example, displays a setting screen on a display device. The setting screen is a screen for creating and checking setting data and has items (cells) indicating the setting data. Then, an administrator or the like performs engineering work by creating the setting data or the like using the setting screen. Note that this setting screen is prepared not only as a screen for creating and checking setting data for the primary device but also as a screen for creating and checking setting data for the secondary device. Then, the engineering device holds, as engineering data, data obtained from the engineering work by an administrator or the like in one holding unit (database).

[0005] An example of writing setting data to a device by an engineering device in a conventional facility monitoring system is shown in FIG. 10. As shown in FIG. 10, in the conventional facility monitoring system 2000, the engineering device 60 writes the setting data for the primary device 70 among the engineering data held in the holding unit to the primary device 70. Further, the engineering device 60 writes the setting data for the secondary device 80 among the engineering data held in the holding unit to the secondary device 80. Note that an administrator or the like usually writes the setting data for the primary device 70 first and then writes the setting data for the secondary device 80. Conversely, however, depending on the need, the writing of the setting data for the secondary device 80 may be performed prior to the writing of the setting data for the primary device 70 (advance adjustment).

[0006] Also, the above other example is shown in FIG. 11. As shown in FIG. 11, for the primary device 70, similar to FIG. 10, the engineering device 60 writes the setting data for the primary device 70 among the engineering data held in the holding unit to the primary device 70 (reference sign (1)). On the other hand, for the secondary device 80, the engineering device 60 may directly connect to the secondary device 80 installed at the site after factory shipment by the pre-installed "connect mode" and write the setting data (reference sign (2)). Note that in the "connect mode", the engineering device 60 can directly connect to the devices in the network, edit the setting data for the connected device, etc., and can also acquire (backup) the setting data from the device.

[0007] In addition, since the secondary device 80 often has a similar configuration, when the writing of the setting data for one secondary device 80 is completed, the setting data may be backed up, and the backed-up setting data 810 may be deployed to other secondary devices 80 (reference sign (3)). Also, after the deployment of the backed-up setting data 810, the setting data 810 may be partially changed in the destination secondary device 80.

Summary of the Invention

Problems to be Solved by the Invention

[0009] By the way, in the facility monitoring system 2000, generally, since the number of secondary devices 80 is large, the capacity of the setting data for the secondary devices 80 also becomes large, and as a result, the capacity of the engineering data held in the engineering device 60 also becomes large. Note that in the facility monitoring system 2000, the engineering data held in the engineering device 60 is managed as master data.

[0010] On the other hand, when editing (creating, changing, deleting, etc.) engineering data, a plurality of administrators (engineers) etc. may be involved. For example, as shown in FIG. 12, the editing of the setting data for the primary device 70 is performed by administrator A and administrator B, and the editing of the setting data for the secondary device 80 is performed by administrator C and administrator D. In such a case, if the capacity of the engineering data held in the holding unit 610 of the engineering device 60 is large, there is a problem that the efficiency of the engineering work may decrease, such as the need to divide and transfer the engineering data among multiple data when transferring the engineering data between administrators.

[0011] The present invention has been made to solve the above problems, and an object thereof is to provide an engineering device capable of suppressing a decrease in the efficiency of engineering work accompanying an increase in the capacity of engineering data.

Means for Solving the Problems

[0012] The engineering device according to the present invention includes a reception unit that receives a deletion instruction to delete setting data set in a device belonging to a layer lower than the layer to which an arbitrary device among the devices belongs, from engineering data that summarizes the setting data set in each device in a network in which a plurality of layers to which one or more devices belong are stacked, and a deletion unit that deletes the setting data set in the device belonging to a layer lower than the layer to which the arbitrary device belongs, from the engineering data, based on the deletion instruction received by the reception unit.

Advantages of the Invention

[0013] According to the present invention, since it is configured as described above, it is possible to suppress a decrease in the efficiency of engineering work associated with an increase in the capacity of engineering data.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Embodiment 1. FIG. 1 is a diagram showing a configuration example of a facility monitoring system 1000 including an engineering device 10 according to Embodiment 1. As shown in FIG. 1, the facility monitoring system 1000 includes an engineering device 10, a primary device 20, and a secondary device 30. The engineering device 10, the primary device 20, and the secondary device 30 are connected via a network.

[0016] In FIG. 1, the facility monitoring system 1000 is provided with one primary device 20 and three secondary devices 30. However, the number of the primary device 20 and the secondary devices 30 is not limited to this. Further, although devices to be controlled or monitored are connected to the secondary device 30, the display of these devices is omitted in FIG. 1.

[0017] The engineering device 10 performs engineering processing including creation of the above-described setting data to construct the facility monitoring system 1000. The setting data is, for example, setting data for the primary device 20 for the primary device 20 to monitor or control subordinate secondary devices 30, and setting data for the secondary device 30 for the secondary device 30 to monitor or control subordinate devices. Further, the engineering device 10 holds, as engineering data, data obtained by combining the setting data for the primary device 20 and the setting data for the secondary device 30 in a holding unit 104 (see FIG. 2).

[0018] The primary device 20 downloads the setting data corresponding to itself from the engineering device 10 among the engineering data held by the engineering device 10, and operates based on the downloaded setting data, thereby monitoring or controlling the subordinate secondary devices 30.

[0019] The secondary device 30 downloads the setting data corresponding to itself from the engineering device 10 among the engineering data held by the engineering device 10, and operates based on the downloaded setting data, thereby monitoring or controlling the subordinate devices. The devices are installed in the facility and are composed of, for example, sensors, thermometers, motors, dampers, or power meters.

[0020] In FIG. 1, the network NW that constitutes the main part of the facility monitoring system 1000 is composed of two layers: an upper layer including the primary device 20 and a lower layer including the secondary device 30. Here, an example in which the network NW is configured by stacking two layers to which one or more devices belong is described, but the network NW is not limited to this, and may be configured by stacking three or more layers to which one or more devices belong.

[0021] Next, a configuration example of the engineering device 10 according to Embodiment 1 will be described with reference to FIG. 2.

[0022] As shown in FIG. 2, the engineering device 10 includes a reception unit 101, a deletion unit 102, a display control unit 103, and a holding unit 104. The engineering device 10 is connected to a display device 50 such as a display.

[0023] The holding unit 104 holds engineering data that summarizes the setting data set for each device in the network NW formed by stacking a plurality of layers to which one or more devices belong. In the example of FIG. 1, the network NW is configured by stacking two layers to which one or more primary devices 20 and one or more secondary devices 30 belong.

[0024] The reception unit 101 receives a deletion instruction from an administrator or the like. The deletion instruction is an instruction to delete the setting data set for devices belonging to a layer lower than the layer to which an arbitrary device belongs from the engineering data held in the holding unit 104, that is, the engineering data obtained by summarizing the setting data set for each device in the network NW in which a plurality of layers to which one or more devices belong are stacked. The method for receiving the deletion instruction by the reception unit 101 is not particularly limited. For example, the reception unit 101 may receive the deletion instruction via an editing screen described later that is displayed on the display device 50 by the display control unit 103.

[0025] Specifically, the display control unit 103 causes the display device 50 to display an editing screen for the setting data set for a device (for example, the primary device 20) selected by an administrator or the like (user) from among the devices in the network NW as an arbitrary device based on the engineering data held in the holding unit 104. Then, when a deletion instruction is given via the editing screen displayed on the display device 50 by an administrator or the like, the reception unit 101 receives the deletion instruction.

[0026] At this time, the display control unit 103 may display an icon for receiving the deletion instruction on the editing screen. In that case, the reception unit 101 receives the deletion instruction when the icon on the editing screen is operated (for example, pressed) by an administrator or the like.

[0027] The deletion unit 102 deletes the setting data set for devices belonging to a layer lower than the layer to which the device selected by an administrator or the like as an arbitrary device belongs from the engineering data held in the holding unit 104 based on the deletion instruction received by the reception unit 101.

[0028] The functions of the reception unit 101, the deletion unit 102, and the display control unit 103 are realized, for example, by a CPU (Central Processing Unit), not shown, provided in the engineering device 10, executing a predetermined program expanded in a memory, not shown. Further, the holding unit 104 is composed of, for example, an HDD (Hard Disc Drive), an SSD (Solid State Drive), or a memory, etc.

[0029] Note that, in FIG. 2, the case where the holding unit 104 is provided inside the engineering device 10 is shown, but the holding unit 104 may be provided outside the engineering device 10.

[0030] Next, an operation example of the engineering device 10 according to Embodiment 1 shown in FIG. 2 will be described. In Embodiment 1, the engineering device 10 mainly performs a deletion process of deleting setting data set in devices belonging to a lower hierarchy than the hierarchy to which the device selected by an administrator or the like belongs from the engineering data. This deletion process will be described with reference to the flowchart of FIG. 3.

[0031] Note that, hereinafter, for the sake of simplicity of explanation, it is assumed that the engineering data is held in the holding unit 104 in advance. Further, an administrator or the like selects the primary device 20 as an arbitrary device, and the display control unit 103 causes the display device 50 to display an editing screen of the setting data set in the primary device 20 in response to this selection. Further, an administrator or the like presses an icon on the editing screen displayed on the display device 50, and the reception unit 101 receives a deletion instruction based on the fact that the icon on the editing screen displayed on the display device 50 has been pressed by the administrator or the like.

[0032] First, the display control unit 103 causes the display device 50 to display an editing screen of the setting data set in the primary device 20 selected by an administrator or the like as an arbitrary device (step ST301).

[0033] An example of this editing screen is shown in FIG. 4. In the editing screen 401 shown in FIG. 4, it is possible to edit (create, change, delete, etc.) the setting data set in the primary device 20. In this case, the setting data to be edited (the setting data for the primary device 20) is the setting data for the primary device 20 included in the engineering data held in the holding unit 104.

[0034] The editing screen 401 shown in FIG. 4 is mainly composed of three regions (an item display region 402, a detailed display region 403, and an operation region 404). Among these, in the item display region 402, a plurality of items constituting the setting data for the primary device 20 and a plurality of items constituting the setting data for the secondary device 30 are displayed in a tree form. Here, the part where the former items are displayed is referred to as the "primary device part 4021", and the part where the latter items are displayed is referred to as the "secondary device part 4022".

[0035] When a desired item is selected from these items by an administrator or the like, the setting data for the selected item is displayed in the detailed display region 403. Also, in the operation region 404, various menus for editing the setting data displayed in the detailed display region 403 are displayed. Although the description is omitted here, the editing screen 401 may include an attribute display region for displaying more detailed information such as the attributes (properties) of the items.

[0036] Here, an administrator or the like can edit the setting data for the primary device 20 by selecting a desired item from the primary device part 4021 displayed in the item display region 402. Similarly, an administrator or the like can edit the setting data for the secondary device 30 by selecting a desired item from the secondary device part 4022 displayed in the item display region 402. At this time, the setting data as the editing source is the setting data included in the engineering data held in the holding unit 104.

[0037] However, for the administrator in charge of editing the setting data for the primary device 20, the setting data for the secondary device 30 is not always necessary, and there are many scenarios where the setting data for the secondary device 30 becomes unnecessary. Also, as described above, the number of secondary devices 30 is large, and the capacity of the setting data for the secondary devices 30 tends to be large.

[0038] Therefore, in the operation area 404, as shown in FIG. 5A, an icon 4041 displayed as "Secondary device information deletion" is displayed. This icon 4041 is for receiving a deletion instruction to delete the setting data set in the secondary device 30 belonging to a lower hierarchy than the primary device 20 selected by the administrator or the like as an arbitrary device from the engineering data. The administrator or the like gives the above-described deletion instruction by pressing this icon 4041.

[0039] The reception unit 101 receives the deletion instruction based on the pressing of the icon 4041 by the administrator or the like (step ST302).

[0040] Next, the deletion unit 102 deletes the setting data set in the secondary device 30 belonging to a lower hierarchy than the primary device 20 from the engineering data held in the holding unit 104 based on the deletion instruction received by the reception unit 101 (step ST303).

[0041] As a result, in the engineering device 10, as shown in FIG. 5B, the setting data set in the secondary device 30 is deleted from the engineering data held in the holding unit 104, and the capacity of the engineering data is reduced. Also, as a result, when the administrator or the like transfers the engineering data by mail or the like, operations such as dividing the data become unnecessary, and the efficiency of the engineering work is improved.

[0042] As described above, according to the first embodiment, the engineering device 10 receives a deletion instruction to delete the setting data set in the devices belonging to the layers lower than the layer to which an arbitrary device among the devices belongs, from the engineering data that summarizes the setting data set in each device in the network NW in which a plurality of layers to which one or more devices belong are stacked. The engineering device 10 includes a reception unit 101 and a deletion unit 102. The reception unit 101 receives the deletion instruction, and the deletion unit 102 deletes, from the engineering data, the setting data set in the devices belonging to the layers lower than the layer to which an arbitrary device belongs, based on the deletion instruction received by the reception unit 101. Thereby, in the engineering device 10, it is possible to suppress a decrease in the efficiency of the engineering work due to an increase in the capacity of the engineering data.

[0043] In particular, as described above, by deleting the setting data set in the secondary devices 30 having a larger number than the primary device 20 from the engineering data held in the holding unit 104, it is possible to effectively suppress a decrease in the efficiency of the engineering work due to an increase in the capacity of the engineering data.

[0044] Note that the setting data for the secondary devices 30 is rarely referred to from other functions (other devices), unlike the setting data for the primary device 20. Further, even if the setting data for the secondary devices 30 is temporarily deleted from the engineering data, it can be restored as the engineering data by being acquired (backed up) from the secondary devices 30 and integrated into the engineering data. From such a background, the engineering device 10 enables the deletion of the setting data for the secondary devices 30 from the engineering data. The restoration of the engineering data will be described in detail in the second embodiment.

[0045] Further, the engineering device 10 includes a display control unit 103 that causes the display device 50 to display an editing screen 401 for the setting data set in the device selected by the user among the devices in the network NW as an arbitrary device. The reception unit 101 receives a deletion instruction via the editing screen 401 displayed on the display device 50 by the display control unit 103. Thus, an administrator or the like can easily give a deletion instruction to the engineering device 10.

[0046] Also, the display control unit 103 causes an icon 4041 for receiving a deletion instruction to be displayed on the editing screen 401, and the reception unit 101 receives a deletion instruction when the icon 4041 on the editing screen 401 is operated by the user. Thus, an administrator or the like can give a deletion instruction to the engineering device 10 by a simple operation of operating the icon 4041.

[0047] Embodiment 2. In Embodiment 1, an example of deleting the setting data set in the device belonging to the layer lower than the layer to which an arbitrary device among the devices belongs from the engineering data obtained by collecting the setting data set in each device in the network NW in which a plurality of layers to which one or more devices belong are stacked has been described. In Embodiment 2, an example of restoring the engineering data in which the setting data has been deleted as described above to the state before deletion will be described.

[0048] In the facility monitoring system 1000, the engineering data held in the holding unit 104 may be managed as master data. In that case, if the engineering data in the holding unit 104 is the engineering data after the above deletion process, since the setting data for the secondary device 30 has been deleted from this data, there is a possibility of hindering subsequent engineering work. Therefore, the engineering device 10 restores the engineering data in the holding unit 104 to the state before the deletion process in response to an instruction from an administrator or the like.

[0049] FIG. 6 is a diagram showing a configuration example of the engineering device 10b according to Embodiment 2. The engineering device 10b according to Embodiment 2 is obtained by adding a communication unit 105, an acquisition unit 106, and a data integration unit 107 to the engineering device 10 according to Embodiment 1. Since the other configurations of the engineering device 10b are the same as those of the engineering device 10 according to Embodiment 1, the same reference numerals are given and the description thereof is omitted.

[0050] The communication unit 105 communicates with each device in the network NW.

[0051] The acquisition unit 106 communicates with the device in which the setting data deleted by the deletion unit 102 is set via the communication unit 105, and acquires the setting data from the device.

[0052] The data integration unit 107 integrates the setting data acquired by the acquisition unit 106 into the engineering data after deletion by the deletion unit 102, and restores the engineering data to the state before deletion.

[0053] Next, an operation example of the engineering device 10b according to Embodiment 2 shown in FIG. 6 will be described. In Embodiment 2, the engineering device 10b mainly performs a restoration process of engineering data. This restoration process will be described with reference to the flowchart of FIG. 7.

[0054] In the following description, it is assumed that the setting data for the secondary device 30 has been deleted from the engineering data by the deletion process described in Embodiment 1, and an example will be described in which the engineering device 10d restores the engineering data with the setting data for the secondary device 30 deleted to the state before deletion.

[0055] First, the acquisition unit 106 communicates with the secondary device 30 via the communication unit 105, and acquires (backs up) the setting data from the secondary device 30 (step ST701).

[0056] Next, the data integration unit 107 integrates the setting data acquired by the acquisition unit 106 into the engineering data held in the holding unit 104 on which the deletion process by the deletion unit 102 has been performed, and restores the engineering data to the state before deletion (step ST702).

[0057] Note that the communication with the secondary device 30 by the acquisition unit 106 and the acquisition (backup) of the setting data are performed in the "connect mode" pre-installed in the engineering device 10. In the "connect mode", the engineering device 10 directly connects to the devices in the network NW, edits the setting data for the connected device, etc., and can also acquire (backup) the setting data from the device as described above.

[0058] Also, the restoration of the engineering data by the data integration unit 107 is performed in the "difference check mode" pre-installed in the engineering device 10. In the "difference check mode", as shown in FIG. 8, the setting data 801 acquired (backed up) from the secondary device 30 is compared with the engineering data held in the holding unit 104 to extract the difference, and the extracted difference can be incorporated into the engineering data held in the holding unit 104.

[0059] Here, since the setting data for the secondary device 30 has been deleted from the engineering data held in the holding unit 104 by the above deletion process, the setting data 801 acquired (backed up) from the secondary device 30 is directly incorporated into the engineering data in the holding unit 104 as the difference.

[0060] In the above description, an example of performing restoration processing according to the flowchart of FIG. 7 has been described. However, an administrator or the like may perform restoration processing by a method other than the above. For example, in the engineering device 10, information regarding the type of the secondary device 30 under the primary device 20 can be grasped by the primary device 20. As setting data for the primary device 20, information regarding the type of the secondary device 30 and the like is registered. Note that this registration is performed in advance by an administrator or the like, for example, via the editing screen 401 of FIG. 4 described above.

[0061] An example of the editing screen in this case is shown in FIG. 9. In the example of FIG. 9, information regarding the type of the secondary device 30 and the like (for example, secondary device type 901 in FIG. 9) can be registered via the editing screen 401. The information regarding the type of the secondary device 30 and the like is registered as setting data for the primary device 20. Therefore, it is not deleted in the above-described deletion processing.

[0062] In addition, the engineering device 10 has a function of automatically generating initial values of setting data for the secondary device 30 based on the information regarding the type of each secondary device 30 registered as described above.

[0063] Therefore, an administrator or the like uses this automatic generation function to once generate initial values of setting data for the secondary device 30. Thereafter, the administrator or the like connects to the secondary device 30 using the above-described "connect mode", and while checking the setting data actually set in the secondary device 30, modifies the automatically generated initial values to the actual setting data, thereby restoring the final engineering data.

[0064] In addition, in the engineering device 10, by performing the above-described restoration process, the preliminary adjustment can be performed without any problems. The preliminary adjustment means that when the primary device 20 and the secondary device 30 exist in the network NW, before creating the setting data for the primary device 20, the setting data for the secondary device 30 is created first, and the created setting data is transmitted to and written into the secondary device 30, or the written setting data is changed.

[0065] The preliminary adjustment is performed for the purpose of, for example, checking the connection between the secondary device 30 and the devices (such as dampers) connected under the secondary device 30 before the setting data for the primary device 20 is created. For example, the secondary device 30 may be installed in the attic or the like together with devices such as dampers during the installation work. However, depending on the progress of the installation work, the construction personnel may not be able to enter the site, and it may become impossible to check the operation of the secondary device 30 installed in the attic or the like. Therefore, by the preliminary adjustment, before the setting data for the primary device 20 is created, the setting data is written to the secondary device 30 and the operation is checked.

[0066] Even when such a preliminary adjustment is performed, the setting data for the secondary device 30 may be deleted from the engineering data by the deletion process described in the first embodiment. However, in the engineering device 10b, as described above, by performing the restoration process of the engineering data by, for example, acquiring (backing up) the setting data from the secondary device 30, the engineering data can be restored to the state before deletion. Therefore, in the engineering device 10b, the preliminary adjustment can be performed without any problems.

[0067] Note that, even when prior adjustment is not performed, that is, when the setting data for the secondary device 30 is created after the setting data for the primary device 20 is created, the engineering data can be restored to the state before deletion by performing the restoration process by the method of acquiring (backing up) the setting data from the secondary device 30 in the same manner as described above.

[0068] As described above, according to the second embodiment, the engineering device 10b includes a communication unit 105 that communicates with each device in the network NW, an acquisition unit 106 that communicates with the device in which the setting data deleted by the deletion unit 102 is set via the communication unit 105 and acquires the setting data from the device, and a data integration unit 107 that integrates the setting data acquired by the acquisition unit 106 into the engineering data after deletion by the deletion unit 102 and restores the engineering data to the state before deletion. Thereby, the engineering device 10 can restore the engineering data for which the deletion process has been performed to the state before deletion. Further, for example, even when the setting data for the secondary device 30 created by the prior adjustment is deleted from the engineering data after the prior adjustment is performed by an administrator or the like, the deleted setting data can be integrated into the engineering data and restored to the state before deletion.

[0069] Note that, within the scope of the invention of the present application, free combinations of each embodiment, or modifications of any component of each embodiment, or omissions of any component in each embodiment are possible.
