It is connected to the bus 48. As described above, the controller 26 of the disaster prevention display device is realized as a hardware environment of a computer.

  Referring to FIG. 1 again, in the database 45, map data of a warning area to be monitored by the disaster prevention receiving board 10 and symbol data indicating the installation locations of various sensors and disaster prevention control devices are registered and managed.

  The first display control unit 40 is a building plane showing device symbols of various disaster prevention devices connected to the disaster prevention receiver 10 in a main screen area 72 largely allocated to the display screen 70 shown in FIG. A map 76 showing the layout is displayed, and an enlarged portion is displayed in the main screen area 72 when a part of the map 76 is enlarged.

  In the display screen 70 of FIG. 3A, a map of a certain floor is displayed in an enlarged state, and on the map 76, sensor symbols 78-1 to 78-6 and device prevention symbols are provided as device symbols of the disaster prevention terminal. Smoke damper symbols 80-1 to 80-6 are displayed.

  The second display control unit 42 provided in the controller 26 of the disaster prevention display device 12 in FIG. 1 displays the current value in the sub screen area 74 that is allocated to a lower position, for example, in the lower right corner of the display screen 70 in FIG. An overall view of the map 76 displayed in the main screen area 72 is reduced and displayed as a reduced overall view 86.

  Further, in the symbol control processing unit 44 provided in the controller 26 of the disaster prevention display device 12 in FIG. 1, a reduced overall view 86 which is an overall view of the map 76 displayed in the sub-screen area 74 in FIG. Only the device symbols whose current state is changing, such as fire alarms, gas leak alarms, sensor function abnormalities, etc., are left, and the symbols of disaster prevention terminal devices whose state has not changed are displayed in a deleted state.

  In the case of FIG. 3A, it has been determined that the detector symbol 78-1 in the map 76 in the main screen area 72 has received a fire signal from the disaster prevention receiver 10 and that a fire is being triggered. For the sensor symbol 78-1 during the fire alarm, the symbol color that was normally displayed in blue, for example, is changed to red during the fire alarm, and the symbol color is changed to red to light or blink.

Since symbols other than the alarm detector symbol 88 are not displayed, the position of the alarm detector symbol 88 can be easily and easily understood without being disturbed by the display of other symbols as seen in the reduced overall view 86. It is possible to appropriately grasp the fire alarm position shown in 76.

  FIG. 4 is an explanatory diagram showing image display processing for generating and displaying a map image and a reduced map image from the map data file in the present embodiment.

  4, the map data file 90 is stored in the database 45 of the controller 26 provided in the disaster prevention display device 12 of FIG. 1, and is created and registered as, for example, two-dimensional CAD data for each floor of the building.

  The map data file 90 includes a header 92, map data 94, and symbol data group 96. The header 92 stores an identifier for identifying a building and a floor in the warning area. Map data 94 is two-dimensional CAD data indicating the layout of a building to be monitored.

  In the symbol data group 96, symbol data 96-1 to 96-n of various sensors including a sensor installed in the disaster prevention monitoring system of FIG. 1 and various disaster prevention control devices such as a smoke prevention damper are stored. Yes.

  Each of the symbol data 96-1 to 96-n stores, for example, information such as a symbol name including a symbol identifier, a map coordinate position, symbol graphic data, a normal display color, and a display color at the time of fire or operation. Has been.

  As shown in FIG. 3A, when the map 76 and the reduced overall view 86 are displayed in the main screen area 72 of the display screen 76, for example, in response to the occurrence of a fire, a fire is generated from the database 45 of the hard disk drive 56 in FIG. The map data file 90 of the place of occurrence is read into the RAM 50, and image data for image display as shown in FIG.

  First, for the map 76 displayed in the main screen area of the display screen 70, the map data 94 is read from the map data file 76 and the map is arranged on the layout layer 98. Further, all the symbol data 96-1 to 96-n are read from the symbol data group 96 and arranged in the symbol layer 100.

  At this time, the sensor symbol is set to be colored as the symbol color at the time of monitoring, but for the sensor symbol that has fired, the display color is changed from blue at the time of monitoring to red and blinking red. Subsequently, a composite layer 102 in which the layout layer 98 and the symbol layer 100 are superimposed is generated, and this is displayed as a map 76 on the display screen 70, and enlarged or reduced as necessary.

  On the other hand, with respect to the reduced overall view 86 displayed in the sub-screen area 74 of the display screen 70, the symbol control processing unit 44 reads out the symbol data 96-1 to 96 -n from the symbol data group 96 and arranges them on the symbol layer 106. In addition, only the symbol data for which a fire has been generated, for example, the symbol data 96-1, is read out and arranged, the display color is changed from blue at the time of monitoring to red, and blinking red.

  Subsequently, a composite layer 108 in which the layout layer 98 and the symbol layer 106 are superimposed is generated, and further reduced by the reduction processing 110 and displayed as a reduced overall view 86 in the sub-screen area of the display screen 70.

  In the sub screen area 74, all abnormal terminals may be displayed, or only a limited number of terminals may be displayed by setting priorities. For example, only a plurality of sensors may be displayed in the order in which the abnormality is detected. Further, the symbols of a control device such as a fire door set to be linked to the displayed abnormality detection terminal may be displayed at the same time so that the linkage relationship can be clearly understood.

  When the sensor that has fired is restored, the symbol control process 104 stops the reading arrangement of the symbol data 96-1 that has fired to the symbol layer 106, thereby The sensor symbol is deleted, and the display switches to the display of the reduced overall view 86 without the symbol.

  Note that the map as shown in FIG. 3A can be displayed even in a steady state where there is no abnormality such as a fire, but in the steady state, all symbols are also displayed on the sub-region screen 74 as in the conventional diagram (B). It may be displayed, or it may be set not to display all symbols.

  FIG. 5 is a flowchart showing the disaster prevention display process according to the present embodiment. The disaster prevention display device 12 provided in the disaster prevention monitoring system of FIG. 1 performs a standby display operation in which a standby screen such as a screen saver is displayed on the liquid crystal display 28 in step S1 in a normal monitoring state.

  Of course, when the operator performs enter operation such as keyboard or mouse operation in the standby operation display state, the screen switches from the standby display operation screen to the initial menu screen, and the appropriate menu is selected from the menu screen. Various types of information stored in the hard disk drive 56 can be displayed.

  On the other hand, when a fire signal is sent from the disaster prevention receiving board 10 in the standby operation display state in step S1, and the fire alarm is determined in step S2, the process proceeds to step S3, and a map of the fire occurrence floor is displayed as shown in FIG. The sensor symbol that is displayed in the main screen area 72 of the screen 70 and that is currently being reported is changed from the normal non-report color (blue) to the report color (red), for example, as the sensor symbol 78-1. Change and blink to indicate the location of the fire on the map.

  Subsequently, in step S4, the entire map is reduced and displayed as a reduced overall view 86, leaving only the sensor symbol currently being fired in the sub-screen area 74. Subsequently, when it is determined in step S5 that there is an enlargement operation by mouse click or the like of the enlargement key 82 provided on the display screen 70, the process proceeds to step S6, for example, the main screen area 72 is centered on the sensor symbol 78-1 being issued. The map 76 is enlarged and displayed. For example, the enlargement operation can be performed in stages, such as double when the enlargement key 82 is operated once, and four times when the enlargement key 82 is operated twice.

  Subsequently, in contrast to the enlarged display of the map 76 in the main screen area 72 associated with the enlargement operation in step S7, the fire alarm signal detector symbol 88 displayed in step S4 for the sub-screen area 74 without depending on the enlargement operation. The reduced overall view 86 of the map leaving only the image is continuously reduced and displayed.

  Subsequently, when it is determined in step S8 that there is an operation by mouse click or the like of the reduction key 84 provided on the display screen 70, the process proceeds to step S9, and the current map 76 is reduced and displayed in the main screen area 72.

  If this reduction operation is after the operation of the enlargement key 82, the enlarged map returns to the original size by the operation of the reduction key 84. When the operation of the reduction key 84 is determined in the display state of the map before enlargement, for example, in addition to the map 76 of the fire occurrence floor, the adjacent upper and lower floor maps are displayed side by side in the main screen area 72, for example. The reduced display is performed.

  Subsequently, in step S10, for the reduced display of the main screen area 72, the same screen as that displayed in step S4 is displayed as it is for the sub-screen area 74. That is, the sub-screen area 74 displays a reduced overall view 86 in which the entire map is reduced with the detector symbol 78-1 being fired.

  Subsequently, in step S11, it is checked whether or not the fire alarm is stopped. When there is no fire alarm signal from the disaster prevention receiving board 10, it is determined that the fire alarm is stopped, and the process proceeds to step S12, and the map 76 in the main screen area 72 is displayed. The notification color (red) of the displayed sensor symbol 78-1 is returned to the non-reporting color (blue).

  Further, in step S13, the alarm detector symbol 88 displayed in the reduced overall view 86 of the sub-screen area 74 is deleted (deleted). When the process associated with the fire alarm stop determination is completed, the process returns to step S2 to wait for the next fire alarm while performing the standby display operation in step S1.

  In addition, the fire alarm signal is sent from the disaster prevention receiving board 10 to the disaster prevention display device 12 continuously with the second and third reports following the first fire forecast signal. May come. When a plurality of fire reports are determined in this way, the first and second reports are displayed in the map 76 displayed in the main screen area 72 every time a fire report is determined in step S2. As in the third report, the sensor symbol being reported is changed to the report color and the report is displayed. However, only a predetermined number of report sensor symbols are displayed in the sub-screen area 74. To do.

  The number of alarm detector symbols displayed in the reduced overall view 86 of the sub-screen area 74 is, for example, up to three. Of course, the number of sensor symbols to be displayed in the sub-screen area 74 may be two, or may be one, or if the number of alarm symbols to be displayed is determined within a range where it is difficult to see even if a plurality of sensor symbols are displayed. Good.

  In the above embodiment, the sensor symbol is taken as an example of the symbol whose state has changed, but the symbol of a control device such as a smoke-proof damper is similar to the sensor symbol, for example, When the state is changed by operating the smoke prevention damper, only the symbol of the active smoke prevention damper is displayed as the symbol whose state has changed in the reduced map displayed in the sub-screen area.

  Moreover, in said embodiment, although the disaster prevention display apparatus was an apparatus prepared separately from the disaster prevention receiving board, you may make it implement this invention with the display apparatus of a disaster prevention receiving board.

  In addition, the above-described embodiment is an apparatus that can enlarge and reduce the map displayed in the main screen area. However, the present invention is not limited to this, and the map displayed in the main screen area can be scrolled. The present invention can be applied even to a disaster prevention display device having a display form in which an overall reduced view is displayed in the screen area. The present invention can also be applied to a disaster prevention display device in which the main screen area and the sub screen area display the same area completely, and the display magnification is different.

  Further, in the above embodiment, the symbol is deleted from the sub-screen area when the detector stops the fire alarm. However, the present invention is not limited to this. You may go to the site, check the situation, and delete the display when you have confirmed the alarm detector on the disaster prevention display.
