FIG. 4 is an enlarged view of the screen in FIG. 3. The screen displayed on the display unit 14 includes a graphic area 30, a time display area 31, an alarm list area 32, a floor selection area 33, and a menu bar 34. Of course, the number and types of areas are not limited to these.

In the graphic area 30, a normal screen, an event occurrence screen, and the like are displayed. The normal screen is a screen that displays a message such as "normal monitoring in progress" during normal times to confirm that the display device 1 has started up and is in a monitoring state. This display changes its position periodically to prevent screen burn-in.

The event occurrence screen is a screen that is displayed when an event occurrence is detected upon receiving status information from the fire alarm equipment, and is displayed based on the updated monitoring map 17a that reflects the status information. It is. FIG. 3 shows an example in which an event occurrence screen 35 is displayed in the graphic area 30. The event occurrence screen 35 is a screen for quickly understanding the location and situation where an alarm has occurred. Specifically, the event occurrence screen 35 is a monitoring map 17a in which terminal devices are represented as symbols on drawings such as floor plans, cross-sectional views, and system diagrams of buildings. This is a screen that displays by blinking and changing colors. The event occurrence screen 35 has a plan view screen and screens such as a sectional view and a system diagram.

The floor plan screen represents terminal devices as symbols on the floor plan of the building, and displays the symbols by blinking or changing color when the status changes, such as when an alarm is issued, activated, or abnormal, so that the location and situation of the alarm can be quickly grasped. This is a screen for Screens such as cross-sectional diagrams and system diagrams are used in cases where it is difficult to grasp the location on a plan view, such as pit division display for self-fire alarm equipment, disaster prevention power display for smoke prevention and fire extinguishing equipment, etc. This screen is used in place of the floor plan when displaying equipment unrelated to the above. On screens such as cross-sectional diagrams and system diagrams, terminal equipment is displayed using symbols in the same way as on plan views, and the symbols blink or change color when the status changes. The event occurrence screen 35 is a screen created under the control of the control unit 11 based on the monitoring map 17a stored in the storage unit 17 and the status information from the fire receiver 2. In the following description, it will be assumed that image data based on the monitoring map 17a is displayed on the event occurrence screen 35, without distinguishing between a plan view screen and a screen such as a sectional view or system diagram.

On the event occurrence screen 35, some areas of the monitoring map 17a of the entire floor stored in the storage unit 17 are displayed. Some of the districts that are displayed are districts that have symbols that have undergone status changes. In other words, the event occurrence screen 35 is a screen showing the event occurrence portion of the monitoring map 17a. If an event such as a warning occurs while the normal screen is being displayed, the area of the monitoring map 17a of the relevant floor having the symbol where the status change has occurred is automatically displayed in the graphic area 30. FIG. 3 shows a state in which a monitoring map of the area where the fire occurred is displayed, out of the monitoring map 17a of the entire fifth floor where the fire occurred. Hereinafter, the monitoring map of the range displayed on the event occurrence screen 35 will be referred to as a partial monitoring map 17b, and will be distinguished from the monitoring map 17a of the entire floor including the portion not displayed on the event occurrence screen 35.

The graphic area 30 is provided with vertical and horizontal scroll bars 30a and 30b. Based on the operation of the scroll bars 30a and 30b, a portion that is not displayed outside the graphic area 30 can be displayed in the graphic area 30.

The time display area 31 displays the current date and time. The alarm list area 32 displays a plurality of latest events, for example, five events, among the events occurring at that time. The floor selection area 33 is an area where selection buttons 33a for each floor of the building are displayed. When the selection button 33a is selected by clicking the mouse 16, a partial monitoring map 17b of the floor corresponding to the selection button 33a is displayed in the graphic area 30. Furthermore, the menu bar 34 is an area that displays various switches.

[Operation explanation]
Next, the operation will be explained. During normal times, the fire receiver 2 grasps the status of each terminal device. During this normal time, a normal screen is displayed on the display unit 14. In addition, the fire receiver 2 monitors and controls the activation of necessary terminal equipment in the event of a fire, and displays signals indicating the status of the terminal equipment (alarm, activation, abnormality, recovery, etc.). Transfer to 1. When this signal is input to the control section 11 of the display device 1 via the interface section 12, the control section 11 detects that an event has occurred.

On the other hand, when the power supplied to the display device 1 is cut off due to a power outage, the display device 1 maintains its functions by being supplied with power from the built-in backup power supply device 6, and the display device 1 maintains its functions under the control of the control unit 11. Turn on the light (LED). If the power outage is restored within the power outage guaranteed time (for example, about 5 minutes) of the backup power supply device 6, or if power supply is started from the emergency power source, the above operation will also be restored. If power is not supplied within the guaranteed power outage time, the control unit 11 automatically performs a shutdown process to prevent damage to the device and data before the battery capacity of the backup power supply device 6 reaches its limit. Stop functioning. Further, when the voltage of the backup power supply drops, the backup power supply device 6 outputs a signal to notify the control unit 11 of the voltage drop. When the control unit 11 detects a voltage drop, it terminates the operation of the display device 1 and issues a stop output to the backup power supply device 6 to control power-off.

[Operation when an event occurs]
Next, the operation when an event occurs will be explained using FIG. 3. The display device 1 detects that an event has occurred when a signal indicating an alarm, activation, abnormality, etc. is received from the fire receiver 2. When an event occurs, the control unit 11 displays a partial monitoring map 17b showing the area where the event occurred in the graphic area 30.

Specifically, for example, when the control unit 11 detects a change in the status (alarm) of the smoke detector 20 installed on the fifth floor based on the signal from the fire receiver 2, the control unit 11 changes the display of the graphic area 30 to The normal screen is switched to the event occurrence screen 35. The event occurrence screen 35 displays a partial monitoring map 17b that includes the area where the smoke detector 20 has been activated, out of the monitoring map 17a for the entire fifth floor. Further, the control unit 11 changes the color of the symbol 20a of the smoke detector 20 to red, for example, and displays it blinking on the partial monitoring map 17b so that the symbol 20a of the smoke detector 20 can be distinguished from other smoke detectors that have not triggered an alarm. . The control unit 11 further surrounds an area, such as a store, in which the smoke detector 20 has been activated, with a frame of, for example, red, and displays a flame symbol superimposed within the frame. Note that this display is an example, and the display at the time of alarm is not limited to the display shown in the figure. Then, the control unit 11 causes the district bell device 23 to ring.

Note that after the normal screen is switched to the event occurrence screen 35 and the first partial monitoring map 17b is displayed in the graphic area 30, the display of the graphic area 30 is changed according to the operator's mouse operation. For example, by operating the scroll bars 30a and 30b, the district displayed in the graphic area 30 is changed, and by operating the selection button 33a of the floor selection area 33, the partial monitoring map 17b of another floor is displayed in the graphic area 30. Or something like that.

When a fire occurs, events occur one after another, such as closing the fire door 24, opening the smoke exhaust port, and setting off the gas leak detector 25. Each time an event occurs, the control unit 11 generates image data in which the symbol of the equipment whose state has changed on the monitoring map 17a is displayed by changing color, blinking, or the like. The image data generated here is image data of the monitoring map 17a of the entire floor. In other words, when a state change occurs in a terminal device placed in the non-display area, the control unit 11 monitors the portion that is not displayed in the graphic area 30 by changing the color of the symbol of the terminal device, etc. Image data of a map 17a (hereinafter referred to as the event-reflected monitoring map 17a) is generated and stored in the storage unit 17.

Then, the control unit 11 displays, in the graphic area 30, a partial monitoring map 17b of the area selected by the operator's operation among the monitoring maps 17a stored in the storage unit 17. Therefore, the operator can check the latest event occurrence status from the event occurrence screen 35 displayed in the graphic area 30. Further, the operator changes the district displayed in the graphic area 30 by operating the scroll bars 30a and 30b, and performs necessary confirmation work and the like.

(Transmission of partial monitoring map 17b)
The control unit 11 transmits the image data of the event occurrence screen 35 from the transmission unit 18 to the external device 19 via the network N every time an event occurs. That is, each time an event occurs and the monitoring map 17a is updated, the transmitting unit 18 transmits the image data of the event occurrence screen 35 based on the partial monitoring map 17b, which is a part of the monitoring map 17a in which the event has been reflected, to the network. It is transmitted from the transmitter 18 to the external device 19 via N. Furthermore, image data of an event occurrence screen 35 for notifying that an alarm has occurred is transmitted from the transmitter 18 to the user terminal 3. The transmission format of the image data is not particularly limited, but it may be sent by attaching it to an e-mail, for example.

The external device 19 that receives the image data from the display device 1 at the receiving section 19a stores the received image data in the storage section 19b so that it can be read from the user terminal 3. Every time image data is sent from the display device 1, the external device 19 updates the storage unit 19b by overwriting the latest image data. For example, when the smoke detector 20 on the 5th floor is activated, the external device 19 receives the partial monitoring map 17b of the 5th floor where the symbol 20a of the smoke detector 20 is displayed as an alarm. Save the image data. Afterwards, when the smoke detector 20 on the 5th floor recovers, the image data of the partial monitoring map 17b on the 5th floor that displays the recovery indication (display before the alarm is issued) sent from the display device 1 is overwritten. . As a result, the storage unit 19b of the external device 19 always stores the latest image data for each floor.

In this way, the display device 1 transmits the image data of the partial monitoring map 17b displayed in the graphic area 30 to the external device 19 every time an event occurs. Then, the external device 19 stores the image data of the partial monitoring map 17b from the display device 1 in the storage unit 19b so as to be readable from the user terminal 3. Therefore, the disaster prevention manager accesses the external device 19 from his user terminal 3 through the network N, reads out the image data of the partial monitoring map 17b stored in the storage section 19b, and displays it on the display section of the user terminal 3. can be done. Note that the user terminal 3 only needs to have the function of displaying image data, and does not need to have a disaster prevention application or a specific browser installed. Furthermore, the latest image data for each floor is stored in the storage unit 19b, as described above. Therefore, the disaster prevention manager can check the latest situation for each floor on the user terminal 3.

As described above, the disaster prevention manager can check the situation at the time of event occurrence from a location other than the location where the display device 1 is installed, without going to the location where the display device 1 is installed. Specifically, the disaster prevention manager can check the partial monitoring map 17b displayed in the graphic area 30 when an event occurs.

[Video saving operation]
Next, the video storage operation will be explained. When a fire occurs, the operator uses the mouse 16 to check, for example, that the fire doors 24 installed in areas not displayed in the graphic area 30 have automatically closed, or that the smoke evacuation machine 26 has been activated. Perform tasks such as checking to see if there are any. In the former operation, the operator uses the mouse 16 to operate the scroll bars 30a and 30b to display the fire door 24 on the graphic area 30. In the latter work, the operator also uses the mouse 1 to press the selection button 33a in the floor selection area 33 so that the partial monitoring map 17b of the floor where the smoke evacuation machine 26 is installed, which is different from the 5th floor where the fire occurred, is displayed. Click to perform operations such as switching screens.

In order to enable such post-analysis of operator operations, the control unit 11 performs the following processing. When an event occurs, the control unit 11 first retrieves from the storage unit 17 a moving image of the screen displayed on the graphic area 30, that is, a moving image of the event occurrence screen 35 for a predetermined time T (for example, 3 minutes) before and after the event occurs. get. The storage unit 17 stores the video of the event occurrence screen 35 for a preset data capacity, and when the data capacity becomes full, the old data is deleted and new data is overwritten. It has become so.

Since the moving image of the event occurrence screen 35 is stored in the storage section 17 in this manner, the control section 11 acquires from the storage section 17 the moving image of the event occurrence screen 35 for the predetermined time T before and after the event occurrence. In addition, in a situation where events occur one after another and the interval between event occurrences is shorter than a predetermined time T, the video for the predetermined time T from the first event occurrence to the last event occurrence and before and after that time is displayed. Just get it.

Then, the control unit 11 transmits the acquired video from the transmitting unit 18 to the external device 19 via the network N. The external device 19 that has received the moving image from the display device 1 stores the received moving image in the storage unit 19b so that it can be read from the user terminal 3.

By saving the video of the event occurrence screen 35 at the predetermined time T before and after the event occurrence in the storage unit 19b of the external device 19 as described above, the disaster prevention manager can , can access the external device 19 from their own user terminal 3 and check the video of the event occurrence screen 35. Here, the event occurrence screen 35 is a screen that changes according to input operations performed by the operator using the mouse 16 from the operation input section 15. Therefore, the moving image of the event occurrence screen 35 records the operator's operation of the terminal device, screen switching, the movement trajectory of the mouse 16, and the like. Therefore, the disaster prevention manager can perform a post-mortem analysis of the operator's operation based on the moving image of the event occurrence screen 35.

When performing post-mortem analysis, it is important to check in what order the alarms occurred and what operations the operator performed. Since the events that have occurred are sequentially recorded in the history list, which will be described later, the order in which the alarms occurred can be confirmed by looking at the history list, but operations by the operator are not recorded.

In contrast, in the first embodiment, since the event occurrence screen 35 itself is saved as a moving image as described above, operator operations that are not recorded in the history list can be confirmed, and detailed post-event analysis is possible.

[Save various lists]
Next, saving of various lists will be explained. FIG. 5 is a diagram showing an example of various lists stored in the storage unit of the display device of the fire alarm equipment according to the first embodiment. The storage unit 17 stores a screen list 171, an alarm list 172, and a history list 173. The display unit 14 displays a list screen in the graphic area 30 based on these lists. To display the list screen, open the submenu by operating "Screen Selection" (not shown) in the menu bar 34, and select "Screen List", "Alarm List", and "History List" displayed in the submenu. By clicking and selecting a desired list from the `` menu with the mouse 16, the selected list can be displayed in the graphic area 30.

The list screen of the screen list 171 displays a list of the number of floors of each floor of the building to be monitored, and the floor where an event is currently occurring is displayed in red or the like. Here, if a fire occurs on the 5th floor, "5th floor" is displayed in red or the like. On the list screen of the alarm list 172, the time and location of the currently occurring event are displayed in red or the like. On the list screen of the history list 173, the events displayed in the alarm list area 32 are displayed as a list, and the latest event is displayed in red or the like. In the history list 173, for example, up to 50,000 events can be checked.

The control unit 11 updates these lists stored in the storage unit 17 every time an event occurs, and transmits the latest list from the transmission unit 18 to the external device 19 via the network N. The external device 19 that has received the list data from the display device 1 stores the received list data in the storage section 19b. Every time list data is transmitted from the display device 1, the external device 19 overwrites the latest list data to update the storage unit 19b. As a result, the latest list is always stored in the storage section 19b of the external device 19.

By storing various lists in the storage unit 19b of the external device 19 as described above, the disaster prevention manager can access the external device 19 from his or her user terminal 3 without having to go to the location where the display device 1 is installed. You can access various lists and check them to help understand the current situation and perform post-mortem analysis.

[Effects of display device 1 of fire alarm equipment]
As described above, the display device 1 of the fire alarm equipment according to the first embodiment includes the transmitter 18 that transmits the image data displayed on the event occurrence screen 35 to the external device 19. In this way, the display device 1 of the fire alarm equipment transmits the image data of the event occurrence screen 35 from the transmitter 18 to the external device 19 so that the event occurrence screen 35 can be checked from a location other than the installation location of the display device 1. can.

Furthermore, the display device 1 of the fire alarm equipment transmits a moving image of the event occurrence screen 35 for a predetermined time T before and after the event occurrence from the transmitter 18 to the external device 19. As a result, the disaster prevention manager can access the external device 19 from his or her user terminal 3, check the video, and perform post-mortem analysis of the operator's operations without having to go to the location where the display device 1 is installed. .

Embodiment 2.
In the first embodiment, the image data of the partial monitoring map 17b is transmitted from the display device 1 to the external device 19 when an event occurs. On the other hand, in the second embodiment, image data of the monitoring map 17a including the portion not displayed on the event occurrence screen 35 is transmitted from the display device 1 to the external device 19. Hereinafter, the content of the second embodiment that is different from the first embodiment will be mainly explained, and the content that is not explained in the second embodiment is the same as the first embodiment.

When a fire occurs, it is also necessary to check the status of equipment in areas not displayed in the graphic area 30. Specifically, for example, it is checked whether the fire doors 24 installed in areas not displayed in the graphic area 30 are closed, and whether equipment that does not need to be operated is being operated by mistake. There are times when you want to do so.

Therefore, every time an event occurs, the control unit 11 of the display device 1 of the second embodiment transfers the image data of the monitoring map 17a including the partial monitoring map 17b, which is the monitoring map 17a on which the event has been reflected, to the network N. The data is transmitted from the transmitter 18 to the external device 19 via the transmitter 18 . The external device 19 that has received the image data from the display device 1 stores the received image data in the storage section 19b. Every time image data is sent from the display device 1, the external device 19 updates the storage unit 19b by overwriting the latest image data. The external device 19 stores image data from the display device 1 in a storage unit 19b so as to be readable from the user terminal 3.

With the above configuration, the disaster prevention manager can check the parts not displayed in the graphic area 30 of the display device 1 by operating the user terminal 3 and displaying the monitoring map 17a on the display section of the user terminal 3. can. When displaying the monitoring map 17a on the display section of the user terminal 3, the monitoring map 17a may be displayed in a reduced size so that the entire area is displayed, or the monitoring map 17a may be displayed in its entirety by pinching out and pinching in using fingers. It can also be displayed enlarged or reduced. This can be done using the default functions of the user terminal 3 such as a smartphone.

Note that in the graphic area 30, a part of the monitoring map 17a is displayed as a partial monitoring map 17b. If the partial monitoring map 17b is a 1x screen, the monitoring map 17a will be 2x, 4x, 8x, or 16x, etc. For example, the double screen is a screen that displays 1/2 of the area of the monitoring map 17a. Looking at it from a different perspective, when the double screen is displayed in the graphic area 30, it can be said that only 1/2 of the area of the monitoring map 17a is displayed in the graphic area 30.

The display device 1 according to the second embodiment transmits image data of the surveillance map 17a including areas not displayed in the graphic area 30 to the external device 19 and stores the image data. Therefore, the disaster prevention manager can grasp the situation of areas not displayed in the graphic area 30 from his own user terminal 3, and can grasp the situation of fire occurrence more accurately and precisely.

[Effects of display device 1 of fire alarm equipment]
As described above, the display device 1 for fire alarm equipment according to the second embodiment has the following effects in addition to obtaining the same effects as those in the first embodiment. The display device 1 transmits image data of the entire monitoring map 17a including the partial monitoring map 17b from the transmitting unit 18 to the external device 19 when an event occurs. Therefore, by accessing the external device 19 from the user terminal 3, the disaster prevention manager can also check the status of the portion not displayed in the graphic area 30.

In the first embodiment described above, it is assumed that there is no need for a disaster prevention application to be installed on the user terminal 3. On the other hand, in order to easily check the current situation when a fire occurs, a disaster prevention application may be installed on the user terminal 3 so that the following display can be performed.

FIG. 6 is a diagram illustrating a display example of a monitoring map on a user terminal of the display system according to the second embodiment. A disaster prevention application is installed on the user terminal 3. When the disaster prevention manager performs a predetermined operation, the user terminal 3 starts a disaster prevention application and displays the monitoring map 17a on the display section of the user terminal 3. The user terminal 3 first displays the latest monitoring map 17a among the monitoring maps 17a stored in the storage section 19b of the external device 19. In the example of FIG. 6, the monitoring map 17a of the fifth floor where the fire occurred is displayed. When the disaster prevention manager performs a so-called swipe operation on the display screen, the user terminal 3 recognizes this as an instruction to display a new monitoring map 17a, and displays the corresponding monitoring map 17a on the first floor.

In this manner, the user terminal 3 can rearrange and display the monitoring maps 17a for each floor in order from the newest to the newest.

Furthermore, in the above embodiment, the external device 19 is described as updating the storage unit 19b by overwriting the latest image data each time image data is sent from the display device 1. Each time the image data is sent, it may be stored in the storage unit 19b as separate image data. In that case, the user terminal 3 may display a plurality of image data stored in the external device 19 side by side, or may display the latest image data, and when a swipe operation is performed, the past images are sequentially displayed. Data may also be displayed. Further, the user terminal 3 may sequentially display past image data at regular intervals. Furthermore, when an event is selected in the history list 173, the user terminal 3 may display the image data at that time.
