Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional system, for the terminal devices in the area where an event has occurred (that is, the terminal devices that are in a state different from the normal state including operation and failure), the display mode of the symbol marks on the floor map changes, so the user can easily select the device whose display mode has changed. However, when the user tries to arbitrarily select a non-operating terminal device, the user has to search for the target terminal device among the plurality of symbol marks on the floor map on the screen and confirm where the terminal device is located on the floor map, and there is a problem that it takes time to search for the target terminal device.

[0005] Therefore, the present invention has been made in view of these points, and an object thereof is to provide a disaster prevention display device that can easily identify a target terminal device from a plurality of terminal devices registered in the disaster prevention system. [Means for solving the problem]

[0006] A disaster prevention display device according to one aspect of the present invention includes a display control unit that displays an image of the monitoring area and a list of the multiple terminal devices on a display unit for displaying the situation in a monitoring area based on signals from a plurality of terminal devices installed in a predetermined monitoring area, and a command acquisition unit that acquires a selection command for selecting one or more designated terminal devices from the plurality of terminal devices included in the list displayed by the display control unit, wherein the display control unit displays a terminal image indicating the location of the one or more designated terminal devices in a manner different from the state in which the device is not selected by the selection command, at a position corresponding to the installation location of the designated terminal device in the image.

[0007] The display control unit may display the terminal image with a predetermined icon image attached at a position corresponding to the designated terminal device, and may display the terminal image without the predetermined icon image at a position corresponding to a non-designated terminal device different from the designated terminal device.

[0008] The display control unit may switch from a state in which the list is displayed to a state in which the list is not displayed, in response to the command acquisition unit acquiring the selection command.

[0009] The display control unit may, in response to the command acquisition unit receiving the selection command, move the position of the list so as not to overlap with the position of the designated terminal device.

[0010] The command acquisition unit may acquire an area designation command to specify one of a plurality of sub-areas included in the monitoring area, and the display control unit may display the list at a position corresponding to the shape of the sub-area indicated by the area designation command.

[0011] The disaster prevention display device further includes a storage unit that stores selected device information relating to one or more selected terminal devices selected by the user of the disaster prevention display device from among the plurality of terminal devices, and the display control unit may switch between displaying the list and an individual list showing all of the stored selected device information.

[0012] The display control unit may, in response to the command acquisition unit acquiring the terminal equipment replacement information, determine whether the identification information of the terminal equipment before replacement included in the replacement information matches one of the identification information of the terminal equipment included in the selected equipment information, and if it is determined that they match, delete the terminal equipment before replacement from the selected equipment information. [Effects of the Invention]

Mode for Carrying Out the Invention

[0015] <First Embodiment> (Overview) First, the overview of the disaster prevention system and the disaster prevention display device according to the present embodiment will be described. This disaster prevention system detects the occurrence of events such as fires and gas leaks and issues fire alarms through terminal devices such as smoke sensors and heat sensors. Each terminal device is connected to the disaster prevention display device via a communication line. Although details will be described later, the disaster prevention display device displays, as an image on the display, in which monitoring area the event has occurred based on information about the above events. However, in addition to when the above events occur, for example, during maintenance inspections of terminal devices, there is a demand for the user to identify the location of the terminal devices to be maintained. The disaster prevention display device according to the present embodiment provides a screen display that makes it easy to visually identify the location of the target terminal device based on a list of a plurality of terminal devices in such a case.

[0016] (Disaster Prevention System 1) Hereinafter, the configuration of the disaster prevention system 1 will be described with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of the disaster prevention system 1. As shown in the figure, the disaster prevention system 1 includes a plurality of terminal devices 10, a repeater 20, a fire receiver 30, and a disaster prevention display device 40.

[0017] (Terminal Device 10 and Repeater 20) As the terminal device 10, a single type of device may be provided, or multiple types of devices may be provided. In this embodiment, multiple types of devices are provided. Specifically, fire detectors such as a smoke detector 11 and a heat detector 12 are provided. The smoke detector 11 is a sensor that detects smoke. The heat detector 12 is a sensor that detects heat. The repeater 20 is a smoke exhaust relay, and a plurality of smoke exhaust terminal devices 13 are connected thereto. Although the smoke exhaust terminal device 13 connected to the repeater 20 may also correspond to the terminal device in the present invention, hereinafter, for the sake of simplicity of explanation, the smoke detector 11 and the heat detector 12 will be described as terminal devices.

[0018] The smoke detector 11, the heat detector 12, and the repeater 20 are all connected to the fire receiver 30 via the communication line 14. In the configuration of this embodiment, a plurality of communication lines 14 are connected to the fire receiver 30, and the smoke detector 11, the heat detector 12, and the repeater 20 are connected to each communication line 14. As an example, each communication line 14 and each device are arranged for each floor of the building where the disaster prevention system 1 is installed.

[0019] (Fire receiver 30) The fire receiver 30 includes a control unit and a display unit (not shown), and is configured to transmit a signal to the terminal device 10 and receive a signal from the terminal device 10. Since a conventionally known fire receiver 30 can be used, detailed description is omitted and will be briefly described below. As an example, the fire receiver 30 polls and calls each terminal device 10.

[0020] The fire receiver 30 receives a response corresponding to the command received during polling, which is returned from the terminal device 10 that has received the polling. The fire receiver 30 determines the operating status and the like of each terminal device 10 based on the received response. The fire receiver 30 identifies the terminal device based on the unique address assigned in advance to each terminal device such as the smoke detector 11 and the heat detector 12. The fire receiver 30 causes the display unit to display the operating status of each terminal device 10, and notifies the user by emitting an alarm sound as necessary.

[0021] The fire alarm receiver 30 transmits information about the operating status and events of the terminal devices 10, collected from the terminal devices 10, to the disaster prevention display device 40. An "event" refers to various situations that occur around or within the individual terminal devices 10, and in the case of smoke detectors 11 and heat detectors 12, it refers to whether or not a fire has occurred or malfunctions of these devices themselves.

[0022] (Specific examples of events) Let's consider a scenario where a fire occurs in a specific location on a specific floor of a building. If the fire alarm receiver 30 is located, for example, in a central control room within the building, it is preferable that the display unit of the fire alarm receiver 30 displays the occurrence of the event in a manner that allows the user to confirm which floor and location the fire occurred. To achieve this, the fire alarm receiver 30 stores, in association with the identification information of each terminal device 10, for example, address information, terminal type information, floor information, serial number, terminal number, and the name of the location of the terminal device 10 as table data.

[0023] If a fire occurs in a building, the terminal device 10 corresponding to that location sends back a signal indicating that an event has occurred in response to polling from the fire alarm receiver 30. The fire alarm receiver 30 receives the above signal and displays, for example, that a fire has occurred, the location of the fire, information about the activated terminal device 10, the time, etc., on its display unit. The fire alarm receiver 30 transmits the above information, including the above, to the fire prevention display device 40 (details below).

[0024] (Disaster prevention display device 40) The disaster prevention display device 40 is a device provided separately from the fire alarm receiver 30 to inform the user of the occurrence of an event and the operating status of the terminal equipment 10. As shown in Figure 1, the disaster prevention display device 40 comprises a command input unit 41, a control device 42, and a display unit 43. The command input unit 41 is an input device such as a keyboard or mouse. The display unit 43 is an image display device such as a liquid crystal display. Based on the command input unit 41, the control device 42 appropriately switches the image displayed on the display unit 43. (Control device 42) Next, the detailed configuration of the control device 42 will be described with reference to Figures 2 and 3. Figure 2 is a functional block diagram showing the configuration of the control device 42. Figure 3 is an example of the normal screen display on the display unit 43. As shown in Figure 2, the control device 42 has a storage unit 51 and a control unit 52.

[0025] The memory unit 51 has storage media such as ROM (Read Only Memory), RAM (Random Access Memory), and SSD (Solid State Drive). The memory unit 51 stores programs executed by the control unit 52 and various image files, etc.

[0026] The control unit 52 includes, for example, a CPU (Central Processing Unit). By executing a program stored in the memory unit 51, the control unit 52 functions as a display control unit 61 and a command acquisition unit 62.

[0027] The command acquisition unit 62 receives input commands from the user. Details of the commands received by the command acquisition unit 62 will be described later, along with a diagram showing the specific graphical user interface to be displayed on the disaster prevention display device 40 of this embodiment. The command acquisition unit 62 also acquires various information transmitted by the fire alarm receiver 30.

[0028] The display control unit 61 controls the operation of the display unit 43. The display control unit 61 causes the display unit 43 to display a monitoring screen 70 as shown in Figure 3. The monitoring screen 70 in Figure 3 is the screen that is displayed during normal operation when no events such as fires are occurring. The monitoring screen 70 mainly consists of a main display unit 71, an area designation bar 72, and a menu bar 73.

[0029] (Basic display content of monitoring screen 70) The main display unit 71 occupies the largest area of ​​the entire screen area of ​​the display unit 43. The main display unit 71 displays the image 81 (a floor plan of the indoor area) of the monitoring area and images of the multiple terminal devices 10 placed in the monitoring area (hereinafter referred to as terminal images 82). Here, "image 81" is a schematic layout diagram showing the floor shape of the monitoring area, for example, a floor map of each floor in the case of a multi-story building. The positions where the terminal images 82 are displayed on the image 81 correspond to the actual installation locations of the terminal devices 10 in the monitoring area. In addition, if necessary, the names of rooms, spaces, and equipment included in the monitoring area are displayed as text information on the image 81.

[0030] When a specific event occurs, the designated message field can display the name of the location where the terminal device 10 is located, the address of the terminal device 10, its type, and the type of event (fire, malfunction, etc.).

[0031] The area designation bar 72 is positioned to the right of the main display unit 71, for example. The area designation bar 72 displays icons 83 for selecting sub-areas included in the monitoring area. A sub-area refers to each floor in the case of a multi-story building, for example. In the example in Figure 3, "5th floor" is selected as the sub-area. Image 81 is an image of this sub-area. By hovering the mouse cursor over icon 83 and clicking, it is possible to switch the image 81 of the sub-area displayed on the main display unit 71 as appropriate.

[0032] The menu bar 73 is located above the main display unit 71. The menu bar 73 displays various processes and commands that the user can perform, each represented as an icon 84. The menu bar 73 includes, as an example, items such as "Screen Operation," "Receiver Operation," "Event History (Display)," "Message Memo," "Settings," and "Maintenance" (in Figure 3, only "Maintenance" is labeled with the symbol 84). The following description will mainly detail an example of the screen display when the "Maintenance" menu is selected.

[0033] (Example of screen display during maintenance) The maintenance menu bar 74 is a menu for users to check the location and various information of each terminal device 10. Figure 4 shows an example of the maintenance menu bar 74 screen display. As shown in the figure, the maintenance menu bar 74 is displayed when the "Maintenance" icon on the menu bar 73 is pressed (clicked). The maintenance menu bar 74 lists several icons 85 that indicate various processes, as an example. Specifically, the maintenance menu bar 74 includes the icons 85 for "Symbol List" and "Favorites List". Although Figure 4 also includes various other menus, explanations of their functions are omitted.

[0034] The "Symbol List" icon is used to display a list 91 of terminal devices 10 included in the monitoring area. Figure 5 shows an example of the screen display of the list 91 that appears when this "Symbol List" icon is clicked. The list 91 lists multiple terminal information 92 as text information. Specifically, the list 91 includes the address, floor (sub-area), and location name of each terminal device 10. In Figure 5, the information of all terminal devices 10 is not displayed in the list 91 window; some is hidden. To display the information of the hidden terminal devices 10, the window's sidebar 94 can be moved. In Figure 5, only the list 91 window is shown, but the list 91 window may be displayed as part of the monitoring screen 70 in Figure 3, for example, or it may be displayed on the entire screen.

[0035] (Display to confirm the location of the selected terminal device 10) For example, when maintaining terminal equipment 10, there is a need for users to focus on monitoring the status of specific terminal equipment 10 where events frequently occur. In this way, it is preferable to have a configuration that makes it easy for users to check the location of the terminal equipment 10 on the floor map when selecting the target terminal equipment 10.

[0036] Therefore, in the disaster prevention display device 40 of this embodiment, as shown in Figure 5, when, for example, the second terminal device 10 from the top is selected, an icon image 110 (details below) indicating the location of the terminal device 10 is displayed as shown in Figure 6. Figure 6 is an example of a screen display showing a terminal image 82 with the icon image 110 added.

[0037] As shown in Figure 6, on this screen, the icon image 110 is attached only to the terminal image 82 corresponding to the selected terminal device 10 (shown as designated terminal device 10A in Figure 6). The icon image 110 is, for example, an image in the shape of a "hand" pointing to the terminal image 82, and is an image that makes it easier to visually distinguish the designated terminal device 10A from other terminal devices. On the other hand, terminal images 82 without the icon image 110 are continuously displayed in positions corresponding to unspecified terminal devices that are different from the designated terminal device 10A. In other words, the icon image 110 is not attached to the terminal image 82 of terminal devices 10 that have not been selected by the user selection command.

[0038] In this way, the terminal image 82 indicating the location of the designated terminal device 10A selected from the list 91 is displayed in a different manner than when it is not selected. This makes it easier to distinguish the terminal image 82 of the designated terminal device 10A from others. Therefore, the user can easily identify the location of the target designated terminal device 10A on the image 81 without having to go through the trouble of visually searching for the target terminal device 10 one by one in the image 81.

[0039] To achieve the image display described above, the display control unit 61 (see Figure 2) is specifically configured as follows. When the command acquisition unit 62 receives a selection command from the user to select one or more designated terminal devices 10A from a plurality of terminal devices 10 included in the list 91, the display control unit 61 displays the terminal image 82 in a manner different from the state in which it is not selected by the selection command. Specifically, the display control unit 61 displays the terminal image 82 with a predetermined icon image 110 added to the position corresponding to the designated terminal device 10A. This configuration has the effect of making it easier to identify the designated terminal device 10A from a plurality of terminal devices 10.

[0040] (Display mode that hides Table 91) In the above description, the example given is that the list 91 is displayed overlaid together with the image 81. However, the present invention is not limited to this, and the image 81 may be displayed while the list 91 is hidden, and in that state, the icon image 110 may be displayed on the designated terminal device 10A. In this case, the display control unit 61 switches from a state in which the list 91 is displayed to a state in which the list 91 is not displayed, in response to the command acquisition unit 62 acquiring a selection command. If the image 81 of the monitoring area and the list 91 are displayed simultaneously after the designated terminal device 10A has been selected, the display area of ​​the image 81 becomes small, which may make it difficult to find the location of the designated terminal device 10A. However, by making the list 91 not displayed in response to the command acquisition unit 62 acquiring a selection command, sufficient display area for the image 81 can be secured. This makes it easier to identify the location of the designated terminal device 10A on the image 81.

[0041] (Favorites feature) The "Favorites List" shown in the maintenance menu bar 74 of Figure 4 is a menu for registering a specific terminal device 10 as a favorite. As mentioned above, when a user monitors the status of a specific terminal device 10 where events frequently occur, it is preferable that the terminal device 10 is registered as a favorite in this way, making it easier to find the desired terminal device 10. Therefore, the storage unit 51 of the disaster prevention display device 40 in this embodiment stores selected device information for one or more selected terminal devices selected by the user (favorite registration).

[0042] Favorite registration is performed, for example, by the user clicking the star-shaped icon 93 of the terminal device 10 in the list table 91, as shown in the display state of Figure 5. When the star-shaped icon 93 is clicked, its display color changes from, for example, white to another color such as red or yellow. When the star-shaped icon 93 is clicked, the terminal device 10 is stored in the storage unit 51 as the selected terminal device. For favorite registration, it is also conceivable that a separate window from the list table 91 window is displayed, and a specific terminal device 10 is selected from among multiple terminal devices 10 displayed in that window. However, with a configuration like that of this embodiment, where a list table 91 that displays an icon image 110 indicating the location of the terminal device when it is selected can also be used to register favorites, the user does not need to open a separate window for favorite registration, and it has the advantage of being able to register favorites with a simple operation.

[0043] All terminal devices 10 stored in the storage unit 51 as selected device information by the user will be displayed as selected device information 102 in the "Individual List 101 ("Favorites List")", which is provided separately from the above-mentioned list table 91, when the "Favorites List" icon 85 is selected (see Figure 7). As an example, in Figure 7, the selected device information 102 for the "Presentation Room", which was clicked when the star-shaped icon 93 was clicked in the explanation of Figure 5, is displayed on the first row of the Individual List 101. Specifically, in order to display the Individual List 101, the display control unit 61 displays the information of the selected terminal device (selected device information 102) in the Individual List 101. By registering a specific terminal device 10 as a favorite in this way, it becomes possible to easily identify that selected terminal device without having to search for it in the list table 91 each time. In the Individual List 101, when the user selects a terminal device 10, the icon image 110 may be displayed in the same way as when the terminal device 10 is selected in the list table 91.

[0044] Both the list table 91 and the individual list table 101 may be displayed on the monitoring screen 70, but it is conceivable that having two lists displayed at the same time may make it difficult for the user to check them. Therefore, the display control unit 61 may allow switching between displaying the list table 91 and the individual list table 101.

[0045] <Second Embodiment> Next, a second embodiment of the present invention will be described with reference to Figure 8. Figure 8 is an explanatory diagram showing an example of the screen display of this embodiment when terminal device 10 is selected from the above-mentioned list table 91 or individual list table 101. Components similar to those in the first embodiment are denoted by the same reference numerals, and detailed descriptions are omitted.

[0046] In this embodiment, the display control unit 61 moves the position of the list 91 so as not to overlap with the position of the designated terminal device 10A, in response to the command acquisition unit 62 receiving a selection command from the user.

[0047] Specifically, the screen transitions shown in Figure 8 are performed. When a user selects a specific terminal device 10 from the list table 91 or the individual list table 101, an icon image 110 is added to the terminal image 82 of the designated terminal device 10A, similar to the first embodiment.

[0048] Depending on the position of the designated terminal device 10A on the screen, it may overlap with the display position of the designated terminal device 10A. Here, we assume that the designated terminal device 10A is located within the area indicated by the dashed line in Figure 8. In this case, if the window for list 91 is displayed within this area indicated by the dashed line, the user will not be able to confirm the position of the designated terminal device 10A.

[0049] Therefore, as shown by the arrow in Figure 8, the display control unit 61 moves the position of the individual list 101 to a position that does not overlap with the terminal image 82 to which the icon image 110 is attached, so as not to overlap with the position of the designated terminal device. More specifically, the display control unit 61 automatically moves the position of the individual list 101 towards a blank area or the like. With this configuration, the list 91 and the image of the designated terminal device 10A do not overlap. As a result, it becomes easier to identify the position of the designated terminal device 10A on the image 81.

[0050] Specifically, the above display control may be implemented by the display control unit 61 moving the list 91 to a position where it does not overlap with the designated terminal device 10A or icon image 110 if it is determined that the designated terminal device 10A or icon image 110 is included in the default position where the list 91 is displayed (dashed line area in Figure 8). If it is not determined that the designated terminal device 10A or icon image 110 is included in the default position, the display control unit 61 may display the list 91 in a pre-set default position.

[0051] (Effects of the disaster prevention display device 40) According to the above configuration, the terminal image 82 indicating the location of the designated terminal device 10A selected from the list 91 is displayed in a different manner than when it is not selected. Specifically, as illustrated in Figure 6, the designated terminal device 10A is shown with an icon image 110 attached. This makes it easier to distinguish the terminal image 82 of the designated terminal device 10A from others. Therefore, the location of the target designated terminal device 10A can be easily identified on the image 81 without having to visually search for each terminal device 10 in the image 81.

[0052] <Variation>

[0053] Figure 6 shows an example in which an icon image 110 is added to the terminal image 82 of the designated terminal device 10A. However, instead of adding the icon image 110, the display of the designated terminal device 10A can be changed to a different color than usual, or the terminal image 82 can be made to blink, or any other way that the terminal image 82 is displayed in a manner different from the usual state. It is also possible to combine the addition of the icon image 110 with changing the display color or blinking of the terminal image 82. Even with such a configuration, the user will still be able to easily find the designated terminal device 10A, and the same effect as above, in that the designated terminal device 10A can be easily identified on the image 81, can be obtained.

[0054] When a selection command is issued to multiple designated terminal devices 10A, the display control unit 61 can display the multiple target terminal images 82 in a manner different from the normal state, as described above.

[0055] As a variation, the command acquisition unit 62 may acquire a region designation command (a command generated in response to the user clicking the region designation icon 83) for specifying one of several sub-regions included in the monitoring area, and the display control unit 61 may be configured to display the list 91 at a position corresponding to the shape of the sub-region indicated by the region designation command. For example, in the case of a building where the plan shape differs for each floor (sub-region), the display control unit 61 moves the list 91 to a position on the screen that is easy to see to match these different shapes. More specifically, one example is to move the list 91 or the individual list 101 to a position that does not overlap with the image 81 of the sub-region.

[0056] In this case, depending on the building design, the floor plan may differ from floor to floor (sub-area). If the list table 91 is displayed uniformly in the same position for image 81 of floors with different shapes, there is a risk that the list table 91 and the image 81 will interfere with each other. Therefore, the display control unit 61 displays the list table 91 in a position that does not overlap with the image 81, corresponding to the shape of the sub-area, thereby making both the list table 91 and the image 81 easier to view.

[0057] In the embodiments described above, an icon in the shape of a "hand" was described as an example of the icon image 110, but the icon image 110 may have other shapes. However, it is desirable that the icon image 110 has a different shape, color, or size from the arrow shape of a normal mouse cursor in order to make it easier to visually distinguish it from the mouse cursor.

[0058] (Enlarge image) If the display magnification of the image 81 is small, it is conceivable that even if the icon image 110 is displayed, the user may have difficulty finding the target terminal device 10. Therefore, in the screen display described in each of the embodiments above, the display control unit 61 may be configured to selectively enlarge the display of the terminal image 82 showing the designated terminal device 10A and the surrounding image 81. Specifically, the display control unit 61 enlarges and displays the terminal image 82 and the image 81 when it is determined that the display magnification of the terminal image 82 or the image 81 is smaller than a predetermined threshold. This makes it easier for the user to see the location of the designated terminal device 10A on the screen.

[0059] (Automatically remove from favorites) As mentioned above, the favorites feature is used, for example, when a user wants to monitor a specific device 10 that they want to pay attention to. If the specific device 10 that is the focus of attention is replaced with another device 10 (for example, a new device 10), it is assumed that the device 10 no longer needs to be registered as a favorite.

[0060] Therefore, the display control unit 61 may automatically remove the terminal device 10 from the favorites list when the terminal device 10 is replaced.

[0061] Specifically, as shown in Figure 9, when a terminal device 10 is replaced (step S1), the fire alarm receiver 30 first detects the replacement of the terminal device 10. In addition, as the replacement changes the identification information of the terminal device 10 (for example, the serial number information unique to the device), the identification information stored in the memory unit is updated (step S2). The fire alarm receiver 30 detects the replacement of the terminal device 10 based on the fact that, for example, the identification information of the terminal device 10 that was associated with a predetermined address information has been changed to the identification information of another terminal device 10.

[0062] Next, the fire alarm receiver 30 sends identification information of the terminal equipment 10 before and after replacement to the display control unit 61 as replacement information for the terminal equipment 10 (step S3). In response to the replacement information being acquired by the command acquisition unit 62, the display control unit 61 acquires the identification information of the terminal equipment 10 before replacement included in the replacement information.

[0063] Subsequently, the display control unit 61 determines whether the identification information of the terminal device 10 before replacement matches any one of the identification information of terminal devices 10 stored in the storage unit 51 as selected device information (step S4). If the result in step S4 is Yes, the display control unit 61 removes the terminal device 10 before replacement from the selected device information, thereby canceling the favorite registration of the terminal device 10 (step S5). On the other hand, if the result in step S4 is No, the favorite registration of the terminal device 10 as selected device information is maintained (step S6).

[0064] With this configuration, when terminal device 10 is replaced, terminal device 10 is automatically removed from the favorites list, thus saving the user the trouble of manually removing it from their favorites list.

[0065] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments, and various modifications and changes are possible within the scope of its gist. For example, all or part of the apparatus can be configured by functionally or physically distributing and integrating in any unit.
