Abstract

PROBLEM TO BE SOLVED: To safely and automatically turn off the electric power without breaking a program such as monitor software so that the device will be started up normally next time by providing a control means which receives a source voltage drop signal from a backup power unit, and then performs stopping process operation to stop the device. SOLUTION: The backup power unit 6 outputs the voltage drop signal generated in the case of a power failure or when the backup source voltage drops to a control part 11, which outputs a stop output signal for power-down control to the backup power unit 6. Those signals enable the control part 11 to safely stop after completing access to data when the power source drops to a certain extent since data stored in a storage part 17 are possibly broken if the power source drops to some extent; and subsequent input is not accepted and the stand-by power unit 6 stops at the same time in response to the stop output signal.

Signals may be transmitted to a panel other than the fire receiver 2 connected to the computer, and information may be transmitted to and received from an emergency broadcast facility, a building management facility, or the like.

An image output unit 13 outputs an image to be displayed by the control unit 11, a CRT display unit 14 connected to the image output unit 13 and displaying the image on a CRT, and 15 a CRT.
An operation input unit connected to a mouse 16 for displaying a pointer and moving it, and for determining an input, and a storage unit 17 for storing data obtained by programming the operation of the control unit 11 and image data to be projected. Reference numeral 18 denotes an FD driving unit (floppy disk driver) that writes and reads data to and from the storage medium 3 under the control of the control unit 11. The image on the CRT display unit 14 does not necessarily have to be a CRT,
The display may be a plasma display or the like, and the entire display device 1 may be incorporated in the fire receiver 2 and the CRT display unit 14 may be used as a display unit (not shown) of the fire receiver 2 itself.

FIG. 2 shows a basic configuration of a screen on the CRT display section 14. The graphic area (screen display area), menu bar, time display area, common operation area, event list area (report display area), and It consists of six areas: a system message area (status display area). Of course, the number and type of this area are not limited to this. The graphic area displays a graphic such as a plan view, a cross-sectional view, and a system diagram of the monitored object, the time display area displays the current date and time, and the event list area displays the alarms generated at that time. ,
A plurality of latest warnings, for example, three reports are displayed, and the system message area displays a fire floor display, a mode such as a simulation, and a system state such as a printer stop.

The menu bar is used to call a window such as a guidance / symbol legend, and to specify a maintenance operation.
A frequently used operation switch such as a sound stop is provided.

Examples of screens displayed in the graphic area include an erasing state screen, a menu screen, a plan view screen, a sectional view / system diagram screen, a system screen, a history list screen, and the like. The erasure state screen indicates that the screen is in an erasure state in normal times and there is no abnormal state. During this erasure, as shown in FIG. 3, a small "normal monitoring" is displayed. In this case, it is possible to confirm that the apparatus has been started and is in a monitoring state. In addition, the position of this display changes periodically to prevent screen burn-in. When the mouse is operated in the erased state, a menu is displayed.

The menu screen is a list screen of stored plan views, cross-sectional views, system diagrams, and the like. Switches corresponding to the respective screens are provided. When the switches are operated, the screen is switched to the screen. Also, since the switch turns red on a screen with an alarm, it is possible to check at a glance which screen has an alarm.

On the plan view screen, disaster prevention equipment is represented by symbols on the plan view of the building, and is displayed by blinking or changing colors when the status changes, such as alarm, operation, or abnormality, to indicate the location and status of the alarm. This is a screen for quickly grasping. So-called G
When connected to an R-type receiver, remote control can be performed by selecting a smoke control terminal device symbol on the screen with a mouse. When connected to an analog system type receiver, it is also possible to select an analog sensor symbol with a mouse and display a trend graph. If an alarm occurs during the screen erasure, the corresponding plan view is automatically projected. In addition, when an alarm with a high degree of urgency occurs while displaying any screen, the screen is automatically switched to the first report only for the first report.

Screens such as a sectional view and a system diagram are displayed in a vertical section of a self-fire alarm system, a disaster prevention power display of a smoke prevention / fire extinguishing system, and the like. When displaying equipment unrelated to the location of the report, a sectional view or system diagram is used instead of a plan view. The display of disaster prevention equipment is represented using symbols, as in the plan view.

Further, as shown in FIG. 4, the system screen is a dedicated screen for performing main status display and operation such as interlocking / blocking of various interlocking functions of the disaster prevention system, stopping and restoring sound, etc. It is mainly a function of the GR-type receiver, but this device can also monitor and operate.)

The history list screen (FIG. 10) displays status change information such as alarms and operations that have occurred in the past in a list, which is useful for subsequent analysis. For example, a maximum of 1024 reports can be confirmed.

FIG. 5 shows a window on the screen displayed in the above-mentioned graphic area. The contents that are displayed simultaneously when this window is opened include, for example, guidance, symbol legends, handling explanations, version information, time settings, trend graphs, and the like, which will be described later. Each window can be arbitrarily displayed / erased, and the display position can be arbitrarily changed by moving the mouse pointer to the title bar and moving (dragging) while pressing a button.

As shown in FIG. 6, the guidance is an itemized list of actions to be taken by the disaster prevention center staff when an alarm occurs or the like. For example, "guidance", "gas leakage", "non-fire" There are three types: "report time". In the case of the "fire" and "gas leak" guidances, they are automatically displayed when the first report is issued. The display of this message is a frame having a size obtained by dividing the screen of the CRT display unit 14 into four parts vertically and horizontally, and the position of the frame is selected and projected according to the contents of the screen being projected. You may.
Thereby, display can be performed without affecting the visibility of the lower screen. As shown in FIG. 7, the symbol legend is a description of the type of the equipment symbol used on the graphic screen, the handling description displays a description of the handling of the device, the version information is the program version of the device,
It is possible to confirm the last data update date and the like. In the time setting, as shown in FIG. 8, the time of a built-in clock is set. In addition, the trend graph displays the transition of the sensing level of the analog sensor in a graph. For example, a “3-minute trend” for displaying 3 minutes after the past 3 minutes, and a “weekly” for displaying the past week. There is a trend. This function can be performed only when connected to an analog system type receiver.

Next, a screen switching operation will be described. First, switching of the graphic screen will be described. When switching from the menu screen, a target screen is selected from a list of menu screens (not shown), and the switch is operated to switch. The menu is displayed when the mouse button is pressed from the erased state. When a menu is called from another screen, a "menu" switch in the common operation area is operated. Also, in the case of switching by a switch operation of the common operation area, switching to the menu screen, then switching to the previous screen in the menu registration of the currently projected screen, and then switching to the previous screen in the menu registration of the currently projected screen Switch to the next screen, and then return to the screen that was projected immediately before the currently projected screen, excluding the menu, switch to the system screen, and finally erase the screen (note that there is an alarm Can not be erased in the case).

A switch in the graphic area;
In the case of switching using the key plan, place a “directly above”, “directly below” switch or the same floor in the graphic area.
When the images are displayed separately, the corresponding screen can be switched by providing and operating the corresponding switch. For example, if the user clicks on the immediately above floor switch in the screen, the screen is switched to the screen corresponding to the immediately above floor of the screen being displayed.

Next, a method for displaying a window will be described. Various windows can be projected and deleted as desired. The operation is performed by opening a support menu from the menu bar. Incidentally, when an item on the menu par, for example, a guidance is selected with a mouse, a submenu is opened, and when an item corresponding to a target window on the submenu is operated, the window is displayed.

Next, the operation will be described. In normal times,
The fire receiver 2 grasps the state of each terminal device, and performs monitoring and control for activating necessary devices in the event of a fire or the like. The change in the state includes the operation input from the panel by the operator. Then, the monitoring control information is transmitted to the display device 1. In this normal state, the screen of the CRT display unit 14 of the display device 1 is erased (cannot be erased when there is an alarm). If the screen of the CRT display unit 14 is in the erased state, the screen is displayed as shown in FIG. As shown in FIG. 3, a message indicating that normal monitoring is being performed is displayed.

On the other hand, when the power supply to the display device 1 is interrupted due to the power failure, the function is maintained by the power supply from the built-in standby power supply device 6 and the control unit 11
When the power failure light (LED) is turned on under the control of the above, and the screen is projected on the CRT display unit 14, "power failure" is displayed in the system message area, and the standby power supply unit 6 emits a warning sound, Further, the power failure is recorded and the history list is registered.

When the power failure is recovered within the power failure guarantee time (about 5 minutes) of the backup power supply device 6, or when power supply from the emergency power supply is started, the above operation is also restored. Until the power is not supplied within the power failure guarantee time and the battery capacity of the backup power supply 6 reaches the limit, a shutdown process is automatically performed to prevent destruction of the device and data, and the function is stopped.

That is, between the standby power supply 6 and the control unit 11 of the display device 1, the standby power supply 6
It outputs a voltage drop signal generated at the time of a power failure and a drop in the standby power supply voltage.
A stop output signal for controlling power down is output. These signals are generated when the power of the data stored in the storage unit 17 is lowered while the disk is being accessed.
In order to allow the control unit 11 to safely stop the data, the access to the data has been completed, and the stop is possible so that no further input is accepted. At the same time, the standby power supply is stopped based on the stop output signal. The device 6 is adapted to stop.

The breaker 5 extracts a switch operation notification signal, which is input to the control unit 11 in the same manner as the voltage drop signal of the standby power supply 6. As a result, when the switch of the breaker 5 is turned off, the notification signal enters the control unit 11 of the display device 1, the display device 1 performs an end operation, outputs a stop output to the standby power supply device 6, and stops. That is, the stop operation was performed.

Next, the operation when an alarm is generated will be described with reference to FIG. First, the operations of automatic projection, alarm display, sound sound, and printer printing will be described. When a signal such as an alarm, operation, or abnormality of the disaster prevention equipment is received from a GR-type receiver or the like, the display device 1 performs an alarm operation as follows under the control of the control unit 11. Ring an acoustic device (not shown). A plan view or the like corresponding to the area where the warning has occurred is automatically projected on the CRT display unit 14 (in the case of the erased state). The state of the equipment is displayed on the CRT display unit 14 on a plan view or the like by changing the color of symbols and blinking. Further, in the case of an area display target, the area line is displayed on the CRT display unit 14 by changing the color and blinking. When a fire or gas leak occurs, a window is opened at a position avoiding the symbol on the plan view and the corresponding guidance is displayed. Display a list of alarms that have occurred in the event list area. The generated alarm is recorded in the storage unit 17 and registered in a history list. This information is of course stored in the FD drive unit 18 as needed.
May be stored in the external storage medium 3 via the. These alarm actions are set substantially according to the property specifications and are installed in the apparatus as individual software.

Next, the operation of the fire priority display function will be described. If an alert occurs when the screen is blank,
The display device 1 automatically projects the screen of the district on the CRT display unit 14 only for the first report. Thereafter, the screens are not automatically switched, but are switched manually in principle. However, if any screen was projected manually without an alarm, the screen was projected on the CRT display unit 14 due to an alarm other than a fire such as the operation of a smoke prevention equipment (not shown). In this case, when a fire alarm (self-fire alarm, fire extinguishing, gas leak, emergency call) is generated, the screen is automatically switched to the screen so that the fire alarm is not overlooked.

Next, the operation of the firefighting activity support function will be described. The display device 1 stores the floor where the fire was first fired in the storage unit 17 as the fire floor, and displays it in the system message area on the screen of the CRT display unit 14. For example, when the screen of the fire floor is being projected, “fire floor is being displayed”, and when a screen other than the fire floor is being displayed, “fire floor OOOO
Screen name XXXXX "is displayed. When the fire floor is recognized, the “fire floor” switch in the common operation area is enabled, and by operating the switch, the screen can be switched to the fire floor screen. In each of the plan views, a “direct floor” and “direct lower floor” switch are provided, and a screen being displayed can be directly switched to a screen of a direct upper floor or a direct lower floor. Further, a screen with an alarm can be recognized and switched easily by an alarm screen selection function described later. With these functions, the fire floor, the floor directly above / below the floor, other alarm occurrence status, and the like can be easily grasped.

Next, the operation of the alarm screen selection function will be described. In the common operation area, a plurality of, for example, five "alarm screen selection" switches are prepared, and when an alarm is generated, the control unit 11 of the display device 1 displays the screen first (up).
Assign to the switch. When an alarm is generated on another screen, it is similarly assigned to the next switch. The assigned screen name is displayed on the switch. These switches function to call the screen of the assignment. When the screen is displayed, the switch turns red, and it can be confirmed that the screen is being displayed. This allows you to check which screen has the alarm and which one is currently displayed for the first five screens,
Screen switching can also be easily performed. The "automatic selection" switch sequentially calls a screen with an alarm every time the switch is operated. If there are more than five screens with alarms and a screen other than the five screens corresponding to the alarm screen selection is displayed, the ground of the automatic selection switch turns red and the alarm screen selection switch It can be confirmed that a screen other than the screen assigned to is displayed.

Next, the operation of stopping sound will be described.
During the sounding of the sound, the “sound stop” switch character in the common operation area on the screen of the CRT display unit 14 turns red.
When "Sound Stop" is operated, the sound stops and the characters turn black. If an individual sound stop switch is provided in addition to the screen of the CRT, the sound can be stopped by operating this switch. While the sound is sounding, the switch blinks, and when the switch is operated, the sound stops, and the blinking display on the screen of the CRT display unit 14 also goes out. It should be noted that the sound is sounded when an alarm is generated, and even when the sound is stopped, the sound is sounded again when another alarm is generated (subsequent re-ringing method).

Next, the operation of the area sound and various linkages will be described. Regional sounding performed by GR receiver in case of fire,
The interlocking state (blocking / unblocking) of the smoke prevention equipment and related equipment can be monitored and operated by the device. These monitoring and operations are performed by switching to the system screen (FIG. 4).
Various interlocking switches, fire determination, district sound stop, district sound simultaneous sounding, restoration switch, etc. are provided in the system screen, and the state can be switched when operated. If the switch has been operated, the switch turns red. If any switch is operated (not in the normal position), the character of the “system” screen call-out switch in the common operation area turns red to call attention. The above is the operation when the alarm is generated.

Next, the history function will be described. This function displays and prints status change information such as alarms and operations that occurred in the past, system abnormalities, and the like, for use in subsequent analysis. For example, information up to, for example, 1024 reports can be stored in the storage unit 17 or the storage medium 3, for example. When the information exceeds 1024 reports, old information is overwritten. First, how to project and check the history list screen
Open the submenu by operating “Select Screen” on the menu bar on the screen of the CRT display unit 14 and select “History List”.
Select Then, the screen is switched to a history list screen as shown in FIG. The history list is displayed in chronological order (new information at the top), and [latest] is displayed before the latest information. If the amount of information that can be displayed on the screen is exceeded, the scroll bar on the right side of the screen becomes smaller, indicating that scrolling is possible. Scroll to see the continuation of the history list. Next, the "screen print" switch in the print screen is operated to print information in the range displayed in the screen. To cancel during printing, operate “Cancel printing”.

Next, the simulation function will be described with reference to FIG. This simulation function is a function for causing a device to perform a simulated alarm operation in accordance with a preset scenario, so that disaster prevention center personnel can master the handling of the device in the event of a fire or the like.

The range in which the simulated alarm operates is only the display device 1 (the fire receiver 2 and related devices such as the district level device 23 do not operate), and only the display device 1 can be operated during the simulation. (During the simulation, a message for operating the fire receiver 2 and the emergency broadcast device (not shown) is displayed, but only the message confirmation is performed without operating the actual device).

Next, a description will be given of a method of starting the simulation function and an outline of the operation. First, a submenu is opened from "Handling" on the menu bar of the screen of the CRT display unit 14, and "Simulation" is selected to display a scenario selection window. When a switch corresponding to the scenario stored in the storage unit 17 is displayed, a scenario to be started is selected. Then, the simulation starts and a guide message window opens on the screen. First, a description of “about simulation” is displayed. After confirming the contents, operate the "message confirmation" switch in the window to proceed to the next step.

During the simulation, the CRT display unit 1
"Simulation is starting" is displayed in the system message area of the screen 4. Start simulation
The end / confirmation of each guide message and the simulated alarm operation are printed out and registered in the history list, and can be analyzed later. Also, the "simulation" character is included in the list display / print message of the simulated alarm so that it can be distinguished from the actual alarm.

Proceed to the next step and display "Caution". Confirm the contents and operate "Message Confirmation" in the same way. Proceed to the next step and perform the simulated alarm operation set in the scenario. During the simulated alarm operation, a message as shown in FIG. 11 prompting confirmation of a function alarm is displayed. After confirming the contents of the message and performing the above-mentioned processing, the user operates "message confirmation" and proceeds to the next step. Similarly, by operating the message confirmation, a guide message display and a simulated alarm operation set in the scenario stored in the storage unit 17 are performed.

Depending on the setting of the scenario, a scene appears in which it is necessary to remotely control the smoke and smoke prevention equipment. Therefore, the operation is performed according to the guide. When the scenario reaches the final step, a guide message indicates that the scenario has ended. When "Confirm Message" is operated, the simulation ends and the simulated alarm is restored.

Note that the simulation can be arbitrarily terminated by operating the "premature termination" switch in the guide message window. When the simulation ends halfway, the simulated alarm is restored and the screen displayed before the start is returned. When an actual fire alarm occurs, the screen is forcibly terminated immediately, the simulation alarm is restored, and the screen is switched to the actual fire alarm screen. In this case, a "Simulation forced termination" message is displayed in the system message area of the screen of the CRT display unit 14, indicating that the termination has been forced.

Next, the operation of the simulation function will be described in detail with a specific example. As a basic pattern of the simulation scenario, for example, the following cases can be considered. (1) Pre-alarm → Fire alarm → Smoke control → Fire hydrant activation →
Remote operation of smoke prevention, (2) Fire alarm → Smoke prevention operation → Fire hydrant activation → Smoke vent remote operation, (3) Fire alarm → Smoke prevention operation → Automatic fire extinguishing → Fire extinguishing pump start → Fire door remote Operation, (4) Pre-alarm → Fire alarm → Remote control of fire door, (5) Fire alarm → Remote control of fire door, (6) Fire alarm, (7) Fire alarm → Fire hydrant activation → Fire recovery → Fire hydrant restoration (non-fire report: mischief), (8) Fire report → fire restoration (non-fire report: boya), (9) Gas leak report → gas leak recovery (small gas leak), (10 ) Gas leak notification → Emergency shut-off valve activated (large-scale gas leak).

Since the setting switch for setting is arranged, the time setting in the fire alarm system can be easily performed, and the so-called general operation panel (display device such as a CRT) can be easily stored together with the time as a past history.

Further, in this embodiment, the normal monitoring is displayed on the screen of the display device during normal monitoring, which is almost in a state where the screen is almost erased, so that the operator can recognize the activation state at a glance. In addition, by randomly moving the character display, it is possible to prevent screen burn-in.

In the present embodiment, a switch area in which a predetermined number of selection switches are prepared is set on the screen of the display device, and the screen where an alarm is generated is automatically and individually registered in the selection switches. Therefore, the screen can be partitioned and displayed efficiently.

Further, in the present embodiment, there is provided history storage means for storing a predetermined amount of state change, and medium drive means for storing the predetermined amount of state change in an external storage medium.
Past histories can be easily retrieved and stored.

Further, in the present embodiment, there is provided an operation input screen for displaying a plurality of switches indicating operations for each device and performing input recognition by selecting these switches. When a high switch is selected, a confirmation display for selecting execution or cancellation of the operation execution is performed, so that the confirmation display can be reliably performed.

In the present embodiment, a standby power supply for supplying power to the display device from the commercial power supply via the breaker is provided, and the display device receives a power supply voltage decrease signal from the standby power supply and performs a stop process. Executing the operation to stop and stop the standby power supply, the standby power supply outputs a power supply voltage drop signal when detecting the breaker OFF operation, and the display device controls the breaker OFF operation. When detecting, it executes the stop processing operation and stops and stops the standby power supply, so that it will start normally next time
Power down can be performed safely and automatically, and the input of stop of monitoring software, the input of stop of operation software of display (program can be stopped), the operation of turning off the display, and the operation of turning off the emergency power supply are complicated. Simple steps can be omitted.
