  The four symbols displayed on each button are arranged according to the relative positional relationship on the display screen of the positions 52a to 58a. The symbol corresponding to the position on the display screen associated with the button is displayed so as to be distinguishable from the other three symbols by changing the display form. Specifically, the symbol 222a of the position selection button 202a, the symbol 224a of the position selection button 204a, the symbol 226a of the position selection button 206a, and the symbol 228a of the position selection button 208a are filled in the symbols. It is displayed differently from the symbol display form.

  Further, the position selection button 206a is displayed in a lighter color than the other position selection buttons 202a, 204a, and 208a so as to be identifiable in different display forms. This indicates that the position selection button 206a has been selected and the button cannot be selected (hereinafter referred to as “selection disabled state” as appropriate). That is, the fire and gas leak warning window 200a is displayed at the position 56a corresponding to the position selection button 206a. On the other hand, the display forms of the other position selection buttons 202a, 204a, and 208a indicate that these buttons can be selected and operated (hereinafter referred to as “selectable state” as appropriate).

  The alarm data display unit 210a is displayed at the center of the fire and gas leak alarm window 200a, and includes a fire district display unit 212 and a gas leak district display unit 214. The fire area display unit 212 includes a first area window 212a and a second area window 212b. Alarm data corresponding to the first report of the fire is displayed on the first area window 212a, and a fire is displayed on the second area window 212b. The alarm data corresponding to the second report is displayed. The gas leakage area display unit 214 has the same configuration as the fire area display unit 212. The first area window 214a displays alarm data corresponding to the first report of gas leakage, and the second area window 214b displays gas leakage information. Alarm data corresponding to the second report is displayed. It should be noted that the fire area display section 212 has an event relating to a fire displayed in the fire alarm data section 104a in FIG. 3, and the gas leak area display section 214 has a gas displayed in the gas leak alarm data section 104c in FIG. The same content as the event that occurred for the leak is displayed.

  The window deletion button 216a is displayed at a predetermined position at the upper left end of the fire and gas leak warning window 200a. The window deletion button 216a is displayed in a different form depending on whether the selection is disabled or the selectable state. When there is alarm data in the alarm data display unit 210a, the window deletion button 216a is displayed in a light color as an unselectable state. On the other hand, when there is no alarm data in the alarm data display unit 210a, the window deletion button 216a is displayed in a dark color as a selectable state. That is, the window erase button 216a can be instructed only when all currently displayed alarm data is restored and no new event has been detected. When the window erase button 216a is instructed, the display of the fire and gas leak alarm window 200a is erased.

  Next, the configuration of the fire alarm window 200b will be described.

  FIG. 4B is a diagram illustrating an example of the fire alarm window 200b. The fire alarm window 200b includes position selection buttons 202b to 208b, an alarm data display unit 210b, and a window clear button 216b, as with the fire and gas leak alarm window 200a. The difference from the fire and gas leak alarm window 200a is that the alarm data display section 210b includes only the fire district display section 212. The size of the fire alarm window 200b is smaller than that of the fire and gas leak alarm window 200a because the gas leak area display unit 214 is not provided.

  Next, the configuration of the gas leak alarm window 200c will be described.

  FIG. 4C is a diagram illustrating an example of the gas leak alarm window 200c. Similar to the fire alarm window 200b, the gas leak alarm window 200c includes position selection buttons 202c to 208c, an alarm data display unit 210c, and a window deletion button 216c. The difference from the fire alarm window 200b is that the alarm data display unit 210c includes only the gas leakage area display unit 214. The gas leak alarm window 200c is the same size as the fire alarm window 200b.

  Next, display positions of the fire alarm window 200b and the gas leak alarm window 200c will be described.

  FIG. 5B is a diagram for explaining the positions 52b to 58b when the fire alarm window 200b or the gas leak alarm window 200c is displayed. The positions 52b to 58b indicate the lower left corner, the upper left corner, the upper right corner, and the lower right corner, which are close to the four corners on the display screen, respectively, similarly to the positions 52a to 58a in FIG. The difference from the positions 52a to 58a is that the positions 52b to 58b are closer to the four corners. This is because the size of the fire alarm window 200b and the gas leak alarm window 200c is smaller than that of the fire and gas leak alarm window 200a.

  Next, the operation of the display control process executed by the central control of the CPU 20 will be described in detail with reference to FIGS.

  6 and 7 are flowcharts of the display control process. First, the CPU 20 monitors the occurrence of an event by monitoring whether or not a notification signal is transmitted from the repeater 2 (step 2A). When an alert signal is received, the occurrence of an event is detected (step 2A; Yes), and alarm data indicating the content of the event included in the received alert signal is additionally stored in the accumulated alert data 24 of the RAM 22. (Step 4A).

  Next, the CPU 20 determines whether or not the alarm window 200 is displayed on the display unit 32 (step 6A). When the alarm window 200 is displayed (step 6A; Yes), the CPU 20 monitors whether or not an instruction operation for changing the display position of the alarm window 200 by the operation of the position selection buttons 202 to 208 is performed. (Step 8A). When an operation input indicating that the display position of the alarm window 200 is changed by the operation of the position selection buttons 202 to 208 is detected (step 8A; Yes), the display position associated with the instructed button is displayed. The display of the alarm window 200 is moved (step 10A), the buttons corresponding to the position of the movement destination of the alarm window 200 are set in a non-selectable form, and the other three buttons are displayed in a selectable form (step 12A).

  If the display position changing operation is not detected in step 8A, or after the processing in step 12A, the CPU 20 determines whether there is an event that has returned to the normal monitoring state due to recovery or the like among the currently occurring events. That is, it is determined whether or not there is an ended event (step 14A). If it is determined that there is an ended event (step 14A; Yes), the CPU 20 deletes the alarm data corresponding to the ended event from the accumulated alarm data 24 and deletes it from the alarm window 200 (step 16A). At this time, when there is no alarm data to be displayed on the alarm window 200 (step 18A; Yes), the window deletion button 216 is changed to a selectable form and displayed (step 20A). When an operation input of the window deletion button 216 in the selectable form is detected (step 22A; Yes), the CPU 20 deletes the alarm window 200 from the display unit 32 (step 24A).

  When it is determined in step 6A that the alarm window 200 is not displayed on the display unit 32, when the operation input of the window deletion button 216 is not detected in step 22A, or after the processing of step 24A, the CPU 20 displays the screen switching tab. It is determined whether or not an instruction operation for 106 has been performed (step 30A). If an operation input to the screen switching tab 106 is detected (step 30A; Yes), it is determined whether or not this operation input is an instruction to switch to the alarm screen (step 32A). When it is an instruction to switch to the alarm screen (step 32A; Yes), it is determined whether or not the alarm window 200 is displayed at this time, and when it is displayed (step 34A; Yes), the CPU 20 Then, the display unit 32 is caused to erase the display of the alarm window 200 (step 36A). Thereafter, the display screen of the display unit 32 is switched to the alarm screen (step 38A) including the case where the alarm window 200 is not displayed (step 34A; No).

  On the other hand, when the operation input of the screen switching tab 106 is an instruction to switch to a screen other than the alarm screen (step 32A; No), the CPU 20 changes the screen displayed on the display unit 32 to a screen corresponding to the operation input. Switch (step 40A). Then, the alarm window 200 is displayed at a predetermined display position so as to overlap the switched screen (step 42A). In addition, among the position selection buttons 202 to 208, the button corresponding to the current position where the alarm window 200 is displayed is displayed in a non-selectable form and the other three buttons are displayed in a selectable form (step 44A), and the window is deleted. The button 206 is displayed as a non-selectable form (step 46A).

  When the instruction operation for the screen switching tab 106 is not performed in step 30A, after the process of step 38A or the process of step 46A, the CPU 20 shifts the process to step 2A and repeats the processes of steps 2A to 46A. Execute.

  As described above, according to the disaster prevention receiver 10 of the present embodiment, when the display screen of the display unit 32 is the alarm screen 100 and the alarm data is displayed on the alarm data display unit 210, the screen switching is performed. When an instruction operation is performed, the display screen is switched to the instructed screen, and the alarm window 200 is displayed over the screen. Thereby, it is possible to perform work by displaying a screen other than the alarm screen while constantly monitoring the alarm data. The position where the alarm window 200 is displayed is a predetermined position near the four corners of the screen. Therefore, the display position of the alarm window 200 does not change automatically, and the alarm window 200 can be quickly viewed even in an emergency.

  On the alarm window 200, position selection buttons 202 to 208 corresponding to the display positions 52 to 58 of the alarm window 200 are provided. When any of the buttons is instructed, the button corresponds to the button. The display of the alarm window 200 is moved to the position. Further, among the position selection buttons 202 to 208, the display form of the button corresponding to the current display position of the alarm window 200 is set to the non-selectable state, and the display forms of the other three buttons are set to the selectable state and displayed.

  In addition, four symbols representing the positions 52 to 58 are displayed on the position selection buttons 202 to 208, and the symbol representing the display position of the alarm window 200 corresponding to each button is the other three symbols. Are displayed in different display forms. As a result, the position associated with each button can be intuitively and easily identified, and the operability is improved.

  Further, only when there is no alarm data to be displayed, the display form of the window deletion button 216 of the alarm window 200 is displayed as a selectable state. As a result, it is possible to prevent the alarm window 200 from being accidentally deleted when alarm data exists. When there is no alarm data, the alarm window 200 can be deleted and the entire screen hidden under the alarm window 200 can be displayed.

  When the alarm data to be displayed is a fire and a gas leak, the fire and gas leak alarm window 200a is displayed as the alarm window 200. When the alarm data is a fire, the fire alarm window 200b is displayed and the gas leaks. In this case, a gas leak alarm window 200c is displayed. The fire alarm window 200b and the gas leak alarm window 200c are smaller in size than the fire and gas leak alarm window 200a. As a result, the type of event that is currently occurring can be easily grasped, and the screen portion hidden under the alarm window 200 can be made as small as possible.

  Of the alarm data indicating the contents of the event that is currently occurring, the alarm data of the first report and the second report having high importance are respectively displayed in the first district window 212a, 214a and the second district window 212b, 214b. Thereby, it is possible to perform work by displaying a screen other than the alarm screen while constantly monitoring alarm data having high importance.
