  The transmission / reception unit 21 is a functional unit that transmits and receives various types of information to and from the central monitoring device 1 and the equipment 3a to 3n via the communication line 4.

  The storage unit 22 is a functional unit that stores various types of information related to the operation of the graphic screen generation device 2, and includes a group information DB 221, a monitoring point DB 222, a display setting DB 223, and a drawing DB 224. Here, the group information DB 221 and the monitoring point DB 222 function as a first storage unit in the present invention, and the display setting DB 223 functions as a second storage unit in the present invention.

  The group information DB 221 is a database in which a monitoring point and a group to which the monitoring point belongs are associated and stored. For example, as shown in FIG. 3, the group information DB 221 stores group identification information and monitoring point identification information in association with each other. In FIG. 3, the “group ID” item means group identification information, and the “monitoring point ID” item means monitoring point identification information. For example, a “group ID” of “101” is associated with a record whose “monitoring point ID” is “101-1”, which is associated with a monitoring point whose identification information is “101-1”. This means that the group identification information is “101”.

  The monitoring point DB 222 is composed of a database that stores the monitoring points and the types and display settings of the icons associated with the monitoring points in association with each other, and functions as a first storage unit in the present invention. For example, as shown in FIG. 4, such a monitoring point DB 222 stores monitoring point identification information, corresponding equipment device identification information, icon types, and icon display settings in association with each other. In FIG. 4, the item “equipment device ID” means identification information of the facility device, the item “icon” means the type of icon, and the item “setting” means icon display setting. For example, in the record whose “monitoring point ID” is “101001”, “equipment device ID” of “101”, “icon” of “A”, “setting” of “extinguishing, lighting, flashing”, “ “Display” is associated with “Display”. This is because the monitoring information with the identification information “101001” has the identification information of the associated equipment device “101”, the displayed icon type “A”, the icon display setting “off”, “lighting” ”And“ flashing ”means three patterns.

  The display setting DB 223 is a database that stores the display position of icons displayed on the graphic screen and the presence or absence of display, and functions as the second functional unit in the present invention. For example, as shown in FIG. 5, the display setting DB 223 includes a drawing identification information indicating a figure number, a group identification information, a monitoring point identification information, coordinates on the drawing, and presence / absence of display.

In FIG. 5, the “graph ID” item indicates the drawing identification information, the “coordinate” item indicates the coordinate on the drawing, and the “display presence / absence” item indicates whether the icon is displayed on the drawing. ing. For example, in the record whose “monitoring point ID” is “101-1,” “graph ID” of “1”, “group ID” of “101”, and “coordinate” in the “X” direction of “100”. , “Coordinates” in the “Y” direction of “100” and “display presence / absence” indicating display information of “display” are associated with each other. This is because the icon of the monitoring point with the identification information “101-1” belonging to the group with the identification information “101” has the coordinate in the X-axis direction “100” on the drawing with the identification information “1”, and the Y-axis direction. Means that it is “displayed” at the position “100”.

  The drawing DB 224 is a database storing drawing data such as a plan view and a front view showing the entire building and the layout of each floor of the building. Here, the data is stored as an image file or a file unique to the manufacturer.

  The monitoring point DB 222 may also store group identification information. In this case, the monitoring point DB 222 functions as the first storage unit in the present invention.

  The group setting unit 23 is a functional unit that sets a group to which each monitoring point belongs based on a user operation input such as input using a keyboard. As a result, the monitoring point belongs to any one group. Information regarding the association between the group and the monitoring point set by the group setting unit 23 is stored in the group information DB 221. Note that the monitoring points may be grouped in a predetermined area such as a room or a corridor in a building such as a room unit proposed in Patent Document 1.

  The monitoring point setting unit 24 is a functional unit that sets each monitoring point based on an operation input such as an input using a keyboard, for example. Specifically, the monitoring point, the group to which the monitoring point belongs, the equipment associated with the monitoring point, the icon indicating the monitoring point, the display setting according to the state of the monitoring point, and the like are set in association with each other. Here, the monitoring point is a monitoring target to be monitored by the central monitoring device 1 such as the operating state of the equipment and environmental information such as temperature and humidity, and is associated with at least one of the equipment 3a to 3n. The information is acquired by the equipment 3a to 3n. The monitoring points set by the monitoring point setting unit 24 are stored in the monitoring point DB 222 of the storage unit 22.

  The group selection detection unit 25 selects, for example, one group stored in the monitoring point DB 222, that is, a group of monitoring points to be registered on the graphic screen, based on a user's operation input when dragging and dropping with a mouse. This is a functional unit that detects that the operation has been performed.

  The icon display unit 26 is a functional unit that displays icons on the drawing based on operation results and settings by the group selection detection unit 25, the movement detection unit 28, the display selection unit 29, the display setting DB 223, and the like.

  The display setting unit 27 is a functional unit that sets an icon to be displayed on the graphic screen based on an operation result by the group selection detection unit 25. Specifically, the drawing that displays the icon, the monitoring point corresponding to the icon, the group to which this monitoring point belongs, the position of the icon on the graphic screen, information on whether or not to display the icon on the graphic screen, and the like are associated with each other To set.

<Graphic screen creation operation>
Next, the graphic screen creation operation by the graphic screen generation apparatus 2 according to the present embodiment will be described.

  First, the group information DB 221 and the monitoring point DB 222 are generated in advance. The group information DB 221 and the monitoring point DB 222 are generated by the following procedure as shown in FIG.

  First, the group setting unit 23 sets a group to which a monitoring point belongs based on, for example, a user operation input such as an input using a keyboard (step S1). Specifically, the group identification information is associated with the identification information of the monitoring points belonging to this group. The information associated in this way is stored in the group information DB 221 with the structure shown in FIG. 3 described above.

  When the group is set, the monitoring point setting unit 24 sets the monitoring point based on a user operation input such as input using a keyboard (step S2). Specifically, a monitoring point, equipment associated with the monitoring point, an icon indicating the monitoring point, display settings corresponding to the status of the monitoring point, and the like are associated. The information set in this way is stored in the monitoring point DB 222 in the structure as shown in FIG.

  Thereby, the group information DB 221 and the monitoring point DB 222 are generated.

  After the group information DB 221 and the monitoring point DB 222 are set in this way, a graphic screen is generated according to the procedure shown in FIG. This will be described in detail below.

  First, the group selection detection unit 25 detects whether a group of monitoring points to be registered on the graphic screen has been selected (step S11). The selection includes selecting a position on the drawing where a monitoring point to be registered is arranged and a group including the monitoring point to be registered. As such a selection operation, for example, as shown in FIG. 8, the drawing a corresponding to the graphic screen generated from the drawing DB 224 is displayed on the display screen, and another operation is performed on the drawing a by an operation input by the user. Open the window b, select the group that contains the monitoring point you want to add from the groups listed in this separate window, drag it to the position where you want to add the monitoring point as shown by the arrow c, and drop it at that position You may make it consist of a series of operation | movement. At this time, group identification information stored in the group information DB 221 of the storage unit 22 is listed in the window b.

  When it is detected that a group of monitoring points to be registered is selected on the graphic screen (step S11: YES), the icon display unit 26 and the display setting unit 27 register the monitoring points in units of the selected group. (Step S12). Specifically, the icon display unit 26 arranges icons corresponding to all the monitoring points belonging to the selected group at a position on the selected drawing. Further, the display setting unit 27 displays the selected group, all the monitoring points belonging to this group, a drawing for displaying icons indicating these monitoring points, a position for displaying the icons indicating these monitoring points on the graphic screen, Information relating to whether or not to display the corresponding icon on the graphic screen is associated with the icon and set in the display setting DB 223.

  For example, on the drawing a shown in FIG. 8, among the groups listed in the separate window b, the group whose identification information is “101” is dragged to the position where the monitoring point icon is to be displayed as shown by the arrow c. Suppose that it is dropped at that position.

  Then, based on the group information DB 221 and the monitoring point DB 222, the icon display unit 26 displays all the monitoring points belonging to the dragged group at the dropped position. Here, in the group information DB 221 illustrated in FIG. 3, the monitoring points with the identification information “101-1” to “101-4” are associated with the group with the identification information “101”. Further, in the monitoring point DB 222 shown in FIG. 4, monitoring points whose identification information is “101-1” to “101-4” and icon types are associated. As a result, as shown in FIG. 9, the icons 101-1 to 101-4 of all the monitoring points included in the selected group and the icons 101-1 to 101-4 are surrounded at the dropped position. A frame d is displayed. At this time, for example, the frame d is displayed so that the center of gravity is positioned at the above-described dropped position, and the icons 101-1 to 101-4 are arranged so as to be arranged at equal intervals in the frame d. . Note that the frame d may not be displayed on the display screen.

  In addition, the display setting unit 27 sets information related to the displayed icon and registers it in the display setting DB 223. As described above, when an operation to register a group whose identification information is “101” is detected, the group identification information is based on the group information DB 221 and the monitoring point DB 222 shown in FIGS. 3 and 4. “101”, “1” that is the identification information of the drawing in which the group is dragged and dropped, “101-1” to “101-4” that are the identification information of all the monitoring points belonging to the group, The actual values of the coordinates in the “X” direction and “Y” direction of the icon displayed on the drawing are associated with display information related to whether or not the icon is displayed. Thereby, a display setting DB 223 as shown in FIG. 5 is generated. At this stage, since all the icons are displayed, all the display information regarding the presence / absence of display is set to “display”.

  When the monitoring points are registered in units of groups, the movement detection unit 28 sets the display position of each icon based on the user's operation input (step S13). For example, as shown in FIG. 10, this setting can be performed by dragging the icons 101-1 to 101-4 to the positions displayed on the drawing as indicated by arrows eh and dropping them at the positions. . At this time, as shown in FIG. 11, the display setting unit 27 changes the coordinate value of the monitoring point stored in the display setting DB 223 to the coordinate value of the movement destination (see symbols i and j). As a result, the icon can be moved to an arbitrary position on the graphic screen, so that a graphic screen that is easy to use for the operator can be generated.

  At this time, not only the icon may be moved, but also display information regarding whether or not to display the icon on the drawing may be set. This setting may be performed, for example, by right-clicking on an icon to be hidden to open a menu and selecting an item to be hidden from this menu. As an example, it is assumed that the icon 101-4 illustrated in FIG. 10 is set to non-display. Then, the display selection unit 29 changes the display information stored in the display setting DB 223 from “display” in FIG. 11 to “non-display” as shown in FIG. 12 (see reference k). Then, the icon display unit 26 deletes the icon 101-4 displayed on the graphic screen in FIG. 10 from the graphic drawing as shown in FIG. As a result, monitoring points that are not actually used, monitoring points that do not need to be conscious of the operator, monitoring points that do not have corresponding equipment and the like can be prevented from being displayed on the graphic screen.

  When the icon display position is set, the group selection detection unit 25 confirms whether or not the further monitoring point registration operation has been completed (step S14). This confirmation may be performed, for example, by displaying on the display screen a message asking whether or not to end the monitoring point registration operation. When the monitoring point registration operation is continued (step S14: NO), the group selection detecting unit 25 returns to the process of step S11.

  On the other hand, when the registration operation of the monitoring points is finished (step S14: YES), the screen output unit 31 generates and outputs a graphic screen based on the information stored in the storage unit 22 (step S15). Specifically, based on the display setting DB 223, a drawing corresponding to the graph ID is extracted from the drawing DB 224, and an icon whose display is set to be displayed is placed on the specified coordinates on the drawing. As a result, a graphic screen to be displayed on the display device of the central monitoring device 1 is generated. On this graphic screen, an icon indicating a monitoring point set in the monitoring point DB 222 is arranged at a predetermined position on a predetermined drawing set in the display setting unit 27. In addition, the display state of the icon changes according to the state of the corresponding equipment based on the information set in the monitoring point DB 222. Therefore, the operator of the central monitoring device 1 can monitor the state of the building in which the central monitoring device 1 is disposed by observing the state of the icon on the graphic screen displayed on the display device.

  As described above, according to the present embodiment, when one group stored in the group information DB 221 is selected, each monitoring point belonging to the selected one group corresponds to this monitoring point. Since the position where the icon is displayed on the graphic screen and one group are associated with each other and stored in the display setting DB 223, the icons of all the monitoring points belonging to the one group are displayed on the graphic screen. Since the icon display on the top and the position where the monitoring point and the icon corresponding to this monitoring point are displayed on the graphic screen are associated with the group to which the monitoring point belongs, the graphic screen is more easily displayed. Can be created.

  When a graphic screen is generated by the above-described method or is being generated, the monitoring point DB 222 may be edited to add a new monitoring point. In such a case, the monitoring point may be additionally registered in the display setting DB 223 and displayed on the drawing. For example, as shown in FIG. 14, when a monitoring point of a group with identification information “1” is registered in the display setting DB 223, a monitoring point with identification information “101-5” is added to the group. (See symbol l). Then, the display setting unit 27 adds and sets the display setting corresponding to the monitoring point 101-5 to the display setting DB 223 as shown in FIG. Further, as shown in FIG. 16, the icon display unit 26 displays an icon corresponding to the added monitoring point 101-5 in the frame d where icons belonging to the same group were displayed. As a result, when a new monitoring point is added, a corresponding monitoring point can be added and generated to the monitoring point group registered on the graphic screen and the display setting DB 223 in units of groups. The operability, workability, and certainty at the time can be improved. At this time, additional generation of the corresponding monitoring point may be automatically performed, or may be performed by setting by the display setting unit 27 based on the user's operation input.

Conventionally, for a monitoring point whose icon is not displayed on the graphic screen, information related to this monitoring point is deleted from the display setting DB 223. In such a case, a new monitoring point is added as described above. When added, the monitoring points that are not displayed may be displayed together with new monitoring points. However, according to the present embodiment, by setting the display information, it is possible to prevent the icon of the monitoring point from being displayed without deleting information regarding the monitoring point that is not desired to be displayed from the display setting DB 223.
Note that when a monitoring point is deleted from the monitoring point D222, information associated with the monitoring point stored in the display setting DB 223 may also be deleted.

  In the present embodiment, the case where the central monitoring device 1 and the graphic screen generation device 2 are configured as separate devices has been described as an example. However, they may be configured as a single device.

  The present invention can be applied to a graphic screen generation apparatus of various systems that perform management based on moving image symbols such as icons displayed on the screen.
