  Further, it is also possible to perform a switching display between a plane map and an overhead view map of only the fire floor or a switching display between the display of only the fire floor and the divided screen of FIG.

  FIG. 4 is an explanatory diagram showing image display processing for generating and displaying an overhead map for three floors from the map data file according to the present embodiment.

  In FIG. 4, for example, map data files 90-1 to 90-3 for three floors used for displaying the overhead view map are stored in the database 42 of the controller 26 provided in the disaster prevention display device 12 of FIG. For example, it is created and registered as two-dimensional CAD data for each floor of a building.

  Taking the map data file 90-1 as an example, it comprises a header 92, map data 94, and a symbol data group 96. The header 92 stores an identifier for identifying a building and a floor in the warning area. The map data 94 is two-dimensional CAD data in which the layout of the building to be monitored is created for each floor. In the present embodiment, planar map data and overhead map data are created and registered for each floor.

  The symbol data group 96 stores symbol data of various types of disaster prevention control devices such as various sensors including a fire detector and smoke prevention dampers installed in the disaster prevention monitoring system of FIG.

Each of the symbol data stores, for example, information such as a symbol name including a symbol identifier, map coordinate position, symbol graphic data, normal (monitoring) display color, and fire or operation display color.

  As shown in FIG. 3, when displaying the overhead map of the fire floor, the immediately above floor, and the immediately below floor on the display screen 70, for example, from the database 42 of the hard disk drive 56 of FIG. The map data files 90-1 to 90-3 on the floor and the floor immediately below are read into the RAM 50, and image data for image display as shown in FIG. 4 is generated on the RAM 50.

  In this image data generation process, the overhead map data is read as map data 94 from the map data file 90-1 on the fire floor, and the overhead map is arranged on the layout layer 98. Further, all symbols 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 in blue, which is the symbol color at the time of monitoring, but for the sensor symbol that has detected a fire, the display color is changed from blue at the time of monitoring to red, and red is blinked. The sensor symbol is controlled by a symbol control process 104.

  Subsequently, a composite layer 102 in which the layout layer 98 and the symbol layer 100 are overlapped is generated, and a fire floor overhead map image 72 is generated here. Similarly, the map data file 90-2 on the immediately upper floor and the map data file 90-3 on the immediately lower floor are also displayed on the synthesized floor 102 using the layout layer 98 and the symbol layer 100, and the overhead map image 74 and the floor immediately below. A floor overhead map image 76 is generated.

  At this time, the symbol control processing unit 104 performs control to display and blink the frame of the fire corresponding area on the overhead map on the upper floor and the lower floor corresponding to the fire occurrence area in orange.

  The overhead maps 72, 74, and 76 of the fire floor, the directly above floor, and the immediately below floor generated in the composite layer 102 are displayed as the composite image 105 on the display screen 70.

  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 display operation state, the screen switches from the standby display operation screen to the initial menu screen, and the appropriate menu is selected from the menu screens. Thus, various types of information stored in the hard disk drive 56 can be displayed.

  On the other hand, when the fire detection information 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 the 3D image display mode is set for the fire alarm. It is determined whether or not it has been done.

  If it is determined in step S3 that the 3D image display mode is set, the process proceeds to step S4, where the overhead view map of the fire floor is read from the database and placed on the display memory.

  Subsequently, in step S5, the overhead map on the upper floor is read from the database 42 and placed in the image memory. In step S6, an overhead map on the floor immediately below is read out and placed on the image memory. Subsequently, in step S7, a combined image of the fire floor, the directly upper floor, and the immediately lower floor is displayed on the display screen 70 of the liquid crystal display 28.

  Subsequently, in step S8, the sensor symbol that detects the fire in the overhead map of the fire floor is changed from blue at the time of monitoring to red, and the red is blinked. Next, in step S9, the frame line indicating the fire occurrence area including the sensor symbol that has detected the fire in the overhead map of the fire floor is displayed in a red frame and blinked.

  Subsequently, in step S10, the frame line indicating the fire occurrence corresponding area corresponding to the fire occurrence area in the overhead view of the immediately above floor and the immediately below floor is displayed in orange and blinking. Subsequently, in step S11, the presence or absence of restoration is determined. The overhead map display of the fire floor, the immediately above floor, and the immediately below floor is performed until the restoration is made, and when the recovery is determined, the process returns to the standby display operation in step S1.

  On the other hand, if the fire report is determined and the 3D image display mode is not selected in step S3, the process proceeds to step S12, where the display process of the floor map of the fire floor is performed, which is similar to the conventional display process. The same, if necessary, based on the operation of split screen display, display a plane map of the fire floor, directly above floor, and directly below floor at the three positions of the screen divided into four as shown in FIG. Can do.

  FIG. 6 is an explanatory diagram showing a planar map corresponding to the overhead map of the present embodiment. FIG. 6 (A) is a planar map 106 on the 10th floor, and FIG. 6 (B) is a planar map 110 on the 11th floor. is there.

  The floor map 106 on the 10th floor in FIG. 6 (A) has the same layout as the 1st to 9th floors as shown in the 10th floor layout 106-1, but the 11th floor in FIG. 6 (B). Is the top floor, and therefore the floor area is small as shown in the eleventh floor layout 110-1.

  When the bird's-eye view map corresponding to the planar maps 106 and 110 as shown in FIG. 6 is used, for example, when the 10th floor in FIG. 6A is the fire floor, the fire floor as shown in the display screen 70 in FIG. The overhead map 72, 74, 76 on the upper floor and the lower floor is displayed.

  In the display screen 70 of FIG. 7, the overhead map 74 that is directly above the floor is an overhead map of the 11th floor layout 110-1 having a small floor area, and therefore, the overhead map 72 of the fire floor and the overhead view of the floor immediately below. A bird's-eye view map 74 having a smaller floor area than the map 76 is displayed, and a large empty area is generated on the display screen.

  Therefore, in the present embodiment, the 10th floor plan map 106 in FIG. 8A is the same as FIG. 6A, but the 11th floor plan map 110 in FIG. A planar map 110 having an 11th floor enlarged layout 110-2 shown in FIG. 8B is prepared, and an overhead view map corresponding to the enlarged layout 110-2 is prepared in advance, whereby the 10th floor is designated as the fire floor. In such a case, the overhead map 72, 74, 76 of the fire floor, the directly above floor, and the immediately below floor is displayed as shown in the display screen 70 of FIG.

  For this reason, about the 11th-floor overhead map 74 with a small floor area, an overhead space corresponding to the 11th-floor enlarged layout 110-2 shown in FIG. Even if the floor areas are different, the fire floor, the directly above floor, and the directly below floors 72, 74, and 76 can be displayed on the screen with substantially the same size.

FIG. 10 is an explanatory diagram showing a display state at the time of a fire on the display of the display screen 70 of FIG. In FIG. 10, if the fire detector corresponding to the fire detector symbol 108 detects a fire in the overhead map 72 of the fire floor, the detector symbol 108 is changed from blue at the time of monitoring to red and blinks red. At the same time, a red frame 114 surrounding the fire occurrence area indicated by diagonal lines including the sensor symbol 108 is displayed, and the red frame 114 is blinked.

  On the other hand, the overhead map 74 on the upper floor is displayed as an overhead map 74 in an enlarged size with respect to the overhead maps 72 and 76 on the fire floor and directly below, and corresponds to the red frame 114 indicating the fire occurrence area on the fire floor. For the fire-response area, an orange frame 116 surrounding the area is displayed and blinked.

  At this time, since the bird's-eye view map 74 is displayed in an enlarged manner, the orange frame line 116 indicating the fire occurrence corresponding area is displayed as an enlarged frame line with respect to the red frame line 114 indicating the fire occurrence area on the fire floor. As a result, even if the scales of the overhead maps 72 and 74 on the fire floor and the directly upper floor are different, the correspondence between the fire occurrence area and the fire occurrence response area can be clearly and easily recognized. When the enlargement ratio is displayed on the screen, the actual area is easy to understand.

  On the other hand, since the overhead map 76 on the floor immediately below is the same scale as the overhead map 72 on the fire floor, an orange frame 118 indicating the fire corresponding area is displayed in the same size as the red frame 114 indicating the fire occurrence area. Blinking.

  FIGS. 11, 12, and 13 are explanatory diagrams showing the display screen of the present embodiment that displays the overhead map by changing the angle of overhead. FIG. 11 is a display screen 70 displayed with the angle at which the bird's-eye view is set at a small angle. The fire occurrence area 84 is displayed for the fire floor, and the fire occurrence corresponding areas 86 and 88 are displayed for the upper floor and the lower floor.

  In the menu field on the right side of the display screen 70, an overhead angle up key 120 and an overhead angle down key 122 are provided in addition to the previous screen key 78, the next screen key 80, and the 3D screen key 82.

  When the bird's-eye view angle up key 120 is operated by a mouse click or the like in the state of the display screen 70 in FIG. In the display screen 70 of FIG. 12, the overhead angle of the overhead map 72, 74, 76 on the fire floor, the directly above floor, and the immediately below floor is increased with respect to FIG. It becomes easy.

  When the overhead angle up key 120 is operated by a mouse click or the like in the display state of FIG. 12, the display further changes to the display shown in the display screen 70 of FIG. In the display screen 70 of FIG. 13, the bird's-eye view maps 72, 74, and 76 of the fire floor, the directly upper floor, and the immediately lower floor are increased with respect to FIG. 12, and the map contents are more easily understood.

  In this way, in the present embodiment, the overhead map of the fire floor, the immediately above floor, and the immediately below floor displayed on the display screen 70 in response to the operation input using the overhead angle up key 120 or the overhead angle down key 122 is displayed. The overhead angle, which is the angle looking down from above, can be freely adjusted as necessary.

  Here, in the embodiment for adjusting the overhead angle of FIGS. 11 to 13, when the overhead angle is set to 0 degree, each of the overhead map 72, 74, 76 becomes one line. Since each floor is represented by a single line, a side view of the entire building may be displayed on the screen. Since the height of the display frame for one floor can be varied according to the overhead angle, the number of display stages such as increasing the number of floors to be displayed as the overhead angle is decreased may be changed.

  On the other hand, when the bird's-eye view angle is maximum, that is, 90 degrees, this represents a plane map. In this case, if the display is switched to the plane map display corresponding to the bird's-eye view map 72 displayed in the center. Good.
