Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention displays a plan view of a warning area on a CRT display device together with symbol marks indicating the installation positions of sensors, disaster prevention equipment, etc. The present invention relates to a display device for fire alarm equipment.

(Prior art) In conventional fire alarm equipment, a CRT display device is installed at a monitoring station, and a plan view of an arbitrary warning area is selected by input operation by an operator using a display screen using a light pen, for example. Furthermore, in the event of a fire, a plan view of the restricted area where the fire has occurred is automatically displayed based on the fire detection signal from the fire receiving panel, and the area where the fire has occurred in the restricted area plan is automatically displayed. The location of the fire is displayed in color such as "red" so that the location of the fire can be seen at a glance.

On the other hand, in recent years, in order to detect fires early and prevent false alarms, analog fire sensors such as smoke concentration sensors and temperature sensors have been installed in warning areas, and detection signals from analog fire sensors have been A so-called analog fire alarm system has been developed that determines whether a fire has occurred based on the CR
A plan view of the restricted area is displayed on the T-display device, and symbol marks indicating the installation positions of sensors, fire doors, fire shutters, and other disaster prevention equipment are displayed in the restricted area plan view. The display of symbol marks on sensors and disaster prevention equipment indicates their installation locations, and at the same time, for example, when a sensor signal input exceeds a predetermined level, the corresponding sensor mark flashes to alert the operator. For disaster prevention equipment, display control is being considered that prompts the operator to confirm by flashing the corresponding symbol mark when the disaster prevention equipment starts or stops.

(Problem to be Solved by the Invention) However, if the symbol mark on the display screen is displayed blinking and the display is controlled without prompting the operator's confirmation, many Since the symbol marks of sensors and disaster prevention equipment are displayed, even if the symbol mark blinks to prompt confirmation, all the blinking marks are not confirmed and the display screen returns to the initial erased screen that does not display the restricted area floor plan. You may end up returning it,
There was a risk that unconfirmed information would be left behind.

(Means for Solving the Problems) The present invention has been made in view of the above problems.
To provide a display device for fire alarm equipment that allows an operator to easily confirm that unconfirmed information remains due to blinking symbol marks even if the screen is returned to the initial erased screen, and to ensure that confirmation processing is carried out by an operator. purpose.

In order to achieve this objective, the present invention displays a symbol mark indicating the location of the installation site of Senna, disaster prevention equipment, etc. together with a plan view of the warning area on a CRT display device installed in a monitoring room, etc. When inputting a detection signal from a sensor that exceeds the specified limit, or when inputting a signal to start or stop a disaster prevention device, the corresponding symbol mark will be displayed blinking, and the blinking symbol mark and/or confirmation message plot mark can be confirmed by plotting with a light pen. In a display device of a fire alarm system that is designed to stop blinking, if the initial state is switched to the erased double-sided mode with unconfirmed information remaining due to the blinking symbol mark, the unconfirmed information will be displayed at a predetermined position on the erased screen. The display area indicating the existence of unconfirmed information is displayed as "Tatsumi Tsune" to indicate the existence of unconfirmed information, and when the plot is operated with a pen, the display is switched to a plan view of the restricted area where unconfirmed information is left. This is what I did.

(Example) FIG. 1 is a block diagram showing one embodiment of the present invention.

First, to explain the configuration, 1 is a CR installed in a monitoring room, etc.
The display is controlled by a CRT controller 2, and the CRT controller 2 reads out display data stored in a graphic memory 3 in advance and displays it on the CRT display device 1.

The display data stored in the graphic memory 3 includes a plan view of the warning area to be monitored by the fire alarm equipment;
For example, in a building, etc., a floor plan of a warning area divided by floor is stored as graphic data, and the installation position of an analog fire sensor such as a temperature sensor or a smoke sensor installed in a warning area is stored as graphic data. In addition, symbol marks and display data for displaying the installation positions of disaster prevention equipment such as fire doors, fire shutters, smoke vents, hanging walls, etc. installed in the warning area are also stored.

Furthermore, regarding the display control of the CRT display device @1 and the control operation of the disaster prevention device using the display screen, the present invention uses an input method using the pen 1 and the pen 4, and does not require input from a keyboard, etc. No particular means have been established.

An input operation using the light pen 4 using the display screen of the CRT display device 1 is performed by optically detecting a bright spot caused by the passage of an electron beam when the light pen 4 is plotted at a predetermined position on the display screen. , the plotting position of the light pen 4 is determined from the timing of horizontal and vertical scanning when the beam scanning input is not obtained with the light pen 4, and the corresponding input processing is performed. A pen input circuit 5 allows input operation signals from the light pen 4 using the display screen to be obtained.

Figure 2 shows the CRT display shown in Figure 1.
, is an explanatory diagram showing an example of a displayed warning area plan view.

In FIG. 2, a restricted area plan 6 selected by the input operation of the light pen 4 is displayed on the display screen 1a,
This restricted area plan 6 includes a smoke sensor mark 7 indicating the installation position of the smoke concentration sensor, a temperature sensor mark 8 indicating the installation position of the temperature sensor, a fire door mark 9 indicating the installation position of the fire door, and an evacuation guide light. Guidance light mark 10 indicating the installation position of
etc. are indicated by unique symbols.

Further, on the lower side of the display screen 1a, plot marks 11a to 11h for performing input operations with the light pen 4 are displayed in an array together with messages indicating operation items.

FIG. 3 is an explanatory diagram showing an erased screen of the CRT display device 1 of FIG. 1, and a plan view of the restricted area is displayed on the display screen 1a. If there is no screen, the erased double-sided display state shown in FIG. 3 is obtained, and the date and time are displayed on the upper floor after the erased screen.

Referring again to FIG. 1, the CRT controller 2 receives detection signals from the smoke concentration sensor and temperature sensor installed in the warning area via the confirmation signal latch circuit 12, as well as disaster prevention signals such as fire doors and fire shutters. A signal indicating the control status of the device is being input.

Specifically, sensor data stored in a data memory of a fire receiving board (not shown) is sequentially read out and provided, and when sensor data exceeding a predetermined level is obtained, , the sensor data is applied to the confirmation signal latch circuit 12 and is latched. Regarding disaster prevention equipment, for example, taking control of a fire door as an example, an activation completion signal is given when the fire door is activated and enters a closed state. The sensor detection signal latched by the confirmation signal latch circuit 12 and the activation signal of the disaster prevention equipment, for example, the activation completion signal of the fire door, are transmitted to the CRT.
The controller 2 is instructed to control the flashing of the symbol mark to prompt the operator to perform a confirmation operation. For example, taking the display screen of FIG. 2 as an example, when one smoke density detected by the smoke density sensor exceeds a predetermined level, the corresponding smoke sensor mark 7 will be displayed blinking.

14 and FIG. 1, reference numeral 14 is a confirmation operation detection circuit, and when the light pen 4 performs a confirmation operation by touching the symbol mark blinking on the display screen,
Upon receiving the b-1 recognition operation input from the light pen input circuit 5, the confirmation signal held in the confirmation signal latch circuit 12 is unlatched and the blinking display is stopped. Note that the confirmation operation with the light pen is not performed for each sensor mark, but only by plotting the confirmation plot mark 11f at the bottom of the screen.
All of the symbol marks that are lit may be checked at once.

On the other hand, 15 is an erasing operation detection circuit that detects a plotting operation that switches the display screen by the light pen 4 to the erasing screen shown in FIG. Screen detection circuit 16
outputs a switching signal to the erased screen to the CRT controller 2, so that, for example, the plan view of the guarded area not shown in FIG. 2 is switched to the erased screen shown in FIG. 3.

When a symbol mark is displayed blinking to encourage confirmation operations on such a display screen, confirmation is made by operating a light pen plot of the blinking symbol mark, and furthermore, switching to the initial state clearing screen is performed. In addition, the present invention is provided with an unconfirmed information display circuit 18 that displays in the erase screen that unconfirmed information remains by flashing a symbol mark when switching to the erase screen.

That is, the unconfirmed information display circuit 18 is supplied with a confirmation signal latched by the confirmation signal latch circuit 12, a confirmation signal from the confirmation operation detection circuit 14, and an erase operation signal from the erase operation detection circuit 15. Confirmation signal latch circuit 1
2 is stored in a built-in memory, and each time a confirmation signal is obtained from the confirmation operation detection circuit 14, the corresponding memory confirmation signal is erased, and the erase operation signal is received from the erase operation detection circuit 15. When the stored data of the confirmation information remains when the confirmation information is received, it is assumed that unconfirmed information remains and the CRT controller 2 is controlled to display the presence of the unconfirmed information at a predetermined position on the erased screen, such as "abnormality". command.

FIG. 3 shows an erased screen when the unconfirmed information display circuit 18 gives the CRT controller 2 a display control command indicating the existence of unconfirmed information. A message "abnormality" indicating the presence is displayed together with the plot mark 11. As shown in Figure 3, when the message display "Abnormal" indicating the existence of unconfirmed information is displayed on the deletion screen,
When the plot mark 11 of the message display ``abnormality'' is operated by the light pen 4, the screen is restored to the display screen of the restricted area plan where unconfirmed information is left. Switching to the restricted area plan view in which unconfirmed information remains is performed by the recovery operation detection circuit 19 and the unconfirmed screen recovery circuit 20 shown in FIG. That is, the recovery operation detection circuit 19 detects a plot operation using the light pen to display the message "abnormality" displayed on the erased screen using the light pen, and upon receiving the detection signal of this recovery operation, the unconfirmed screen recovery circuit 20 detects the unconfirmed information. A control signal is output to the CRT controller 2 so as to switch to the display screen of the restricted area plan view where is left.

FIG. 4 is an explanatory diagram showing the system configuration of analog fire alarm equipment to which the display device of the present invention is applied.

In Fig. 4, numeral 21 is a fire reception board, and fire reception!
! From 21, signal lines 22a, 22b,
...22n is drawn out, and each signal line 22a to 2
A smoke concentration sensor 23 and a temperature sensor 24 are connected in parallel to 2n, and each of the smoke concentration sensor 23 and temperature sensor 24 receives call control by polling from the fire reception board 21 (through analog control of smoke concentration and temperature). The fire receiving board 21 compares the data obtained from the sensor through polling with a predetermined fire judgment level, and when the sensor data exceeding the fire judgment level is obtained, it is judged that there is a fire. A fire alarm is issued by ringing a district bell, lighting a fire indicator light, etc.Furthermore, the fire receiving board 21 stores sensor data from the smoke concentration sensor 23 and temperature sensor 24 obtained by calling by polling. A data memory is provided, and data stored in the data memory is sent to the display device of the present invention shown in FIG. 1 to perform various display controls.

In the system configuration shown in FIG. 4, the display control of the present invention shown in FIG. A signal is given. A magnetic disk 26 and a floppy disk 27 are connected to the control device 25 as external storage devices, and these external storage devices have the function of the graphic memory 3 shown in FIG. Graphic data for displaying area plans are permanently stored.

Further, a CRT display device 1 and a light pen 4 are connected to the control device 25 via a CRT controller 2, and two printers for outputting sensor data, control data for external control devices, etc. are also connected to the control device 25. .

Furthermore, the control device 25 includes an external control interface 2B.
is connected to the external control interface 28 to control disaster prevention equipment 3 such as fire doors and shutters installed in the warning area.
Startup and recovery signals are given to 0a, 3Qb, ... 30n, and disaster prevention equipment 308 to 30
A signal indicating its operating state is supplied from n to the control device 25 via an external control interface 28.

Next, display control by the display device of the present invention will be explained with reference to flowcharts in FIGS. 5 and 6.

If a suitable guarded area plan is selected by plotting with the light pen 4, a guarded zone plan 6 as shown in FIG. 2, for example, is displayed on the CRT display device 1.

In the display state of this warning area plan view, the confirmation routine shown in FIG. 5 is being executed.

That is, the determination block 32 checks whether or not there is a confirmation signal. This confirmation signal is, for example, a sensor signal input when the detected smoke concentration or detected temperature from an analog fire sensor exceeds a predetermined level, and for disaster prevention equipment, such as a fire door, when the activation of the fire door is completed. This is the activation completion signal obtained.

When the determination block 32 determines that a confirmation signal has been input from the sensor 1 or disaster prevention equipment, the process proceeds to block 34, where the symbol mark on the display screen corresponding to the confirmation signal is displayed blinking to prompt the operator to operate MIil. .

Next, in the determination block 36, it is determined whether or not there is a confirmation operation by the operator, such as a confirmation Δ* operation using the light pen of the symbol mark that is blinking on the display screen, for example, if any smoke is detected on the display screen in FIG. When the detected smoke level of the concentration sensor exceeds a predetermined level and the smoke sensor mark 7 blinks, use a light pen to plot the blinking smoke sensor mark 7 and check the confirmation plot displayed at the bottom of the screen. By plotting the mark 1'le with a light pen, it is determined that the confirmation operation has been performed. When the confirmation operation by the operator is determined in the determination block 36, the process proceeds to block 38, where the blinking display of the symbol mark that has been confirmed is stopped, and the process returns to the determination block 32 again to wait for the input of the next confirmation signal.

On the other hand, when an erasing operation is performed to switch from displaying a plan view of a guarded area to an erasing screen, the processing is executed by the erasing routine shown in FIG.

In the erasing routine shown in FIG.
monitors whether there is an erase operation. This erasing operation is performed, for example, by plotting the plot mark 11C1 displayed at the bottom of the display screen of the restricted area floor plan in FIG. Switch to display the erase screen.

When the screen is switched to the erase screen shown in FIG. 3 in block 42, the process proceeds to discrimination block 44 to check for the presence or absence of an unconfirmed signal, and if an unconfirmed signal with a flashing symbol mark remains, block 46 proceeds to Then, as shown in FIG. 3, an "abnormal" message is displayed at a predetermined position on the erased screen to notify the operator that unconfirmed information remains. When the operator performs a recovery operation using a light pen after receiving a message display indicating the existence of this unconfirmed information, ``abnormality'', the recovery operation is determined at determination block 48 and the process proceeds to block 50, where the display screen where the unconfirmed information remains. A switching display is displayed.

In addition, a message indicating that unconfirmed information remains on the erased screen is displayed not only when there is unconfirmed information on the display screen before switching, but also when unconfirmed information appears on other restricted area floor plans that are not displayed on the display screen. Similarly, the message "Abnormal" indicating the existence of unconfirmed information will be displayed on the deletion screen.

(Effects of the Invention) As described above, according to the present invention, when a sensor detection signal exceeding a predetermined level is input, or when a signal for starting or stopping disaster prevention equipment is input, a corresponding symbol mark is displayed blinking, so that the operator can When the confirmation operation is prompted and the switch is switched to the initial erase double-sided mode with unconfirmed information remaining due to the blinking symbol mark, a message such as ``abnormality'' indicating the existence of unconfirmed information is displayed at a predetermined position on the erase screen. When you use a light pen to plot the message displayed on the erase screen indicating the existence of unconfirmed information, the display switches to a plan view of the restricted area where unconfirmed information remains, so the symbol mark with the blinking confirmation request is displayed. Even if the operator returns to the erase screen while leaving the data intact, it is immediately clear from the erase screen that unconfirmed information remains, and if confirmation is required, appropriate monitoring of fire alarm equipment equipped with sensors and disaster prevention equipment should be carried out. Can be done.
