Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a display device for fire alarm equipment that displays a plan view of a warning area on a color graphic display.

(Prior art) Conventional fire alarm equipment uses so-called on/off type fire detectors, which determine the presence of a fire using the fire detector itself and send a fire detection signal to a fire receiver. However, in recent years, in order to achieve both early detection of fires and prevention of false alarms, so-called analog fire sensors that output analog detection signals according to temperature and smoke concentration have been installed in warning areas. Progress is being made in the practical application of equipment that collects the detection signals of fires into a fire receiving panel to judge whether or not there is a fire.

By the way, in such analog fire alarm equipment, a color graphic display device is installed in the monitoring room, etc., so that a plan view of the warning area can be displayed on the CRT screen. In the event of a fire, a plan view of the warning zone of the fire outbreak location is displayed on the CRT, and the fire area within the plan map is displayed in color, such as red, so that the location of the fire outbreak can be easily and reliably identified on the CRT screen, and the fire can be extinguished. We ensure that instructions regarding activities and evacuation guidance can be given appropriately.

(Problems to be Solved by the Invention) However, the warning area display device in such conventional analog fire alarm equipment only displays the fire area in color based on the fire judgment. It is not known under what circumstances evacuation sites such as emergency exits and emergency stairs will be needed in the area adjacent to the area where the fire occurred, and it is not until it is determined that the fire has spread that the area becomes dangerous as an evacuation site. As the fire progressed, it was difficult to promptly issue appropriate fire-fighting efforts and evacuation guidance instructions as the fire progressed.

(Means for Solving the Problems) The present invention has been made in view of the above conventional problems.In analog fire alarm equipment, detection information on temperature and smoke concentration in a warning area is always available. Therefore, by effectively utilizing this detection information, the situation of not only the area where the fire occurred but also all sensor installation areas is displayed in color according to the detection level on the floor plan of the warning area, and it is possible to improve firefighting and firefighting activities. It is an object of the present invention to provide a display device for a fire alarm device that can appropriately and quickly issue judgment instructions such as evacuation guidance.

In order to achieve this object, the present invention displays a plan view of a guarded area on a color graphic display device together with a sensor mark indicating the installation position of the guard area, and further divides the plan view of the guarded area into a safety zone and a sensing zone. Divide. Here, the safety zone refers to the central location of the evacuation route, such as the emergency stairwell, surrounding areas, and elevator halls, and other locations are the sensing zone.

Then, the sensor data installed in the warning area displayed on the CRT screen is read in sequence, and the display color is set in stages according to the detection level, and when the sensor data is in the sensing area, the corresponding sensor mark itself is set and the display color is set. On the other hand, when the sensor data indicates a safe zone, the entire corresponding safe zone is displayed in color so as to be filled in with the set display color.

(Embodiment) FIG. 1 is a block diagram showing the basic configuration (claim correspondence diagram) of the present invention.

First, to explain the configuration, numeral 1 is a color graphic display device installed in a monitoring room, etc., which receives display control from a CRT controller 2.
The plan view of the restricted area stored in advance in the graphic memory 3, for example, the plan view of the restricted area prepared for each floor in a building, etc. is read out by the operator's operation and displayed on the color graphic display device 1. It becomes like this.

Furthermore, the plan view of the restricted area stored in the graphic memory 3 also includes display data of sensor marks indicating the installation positions of temperature sensors, smoke sensors, etc. installed in the restricted area.

FIG. 2 is an explanatory diagram showing an example of a plan view of a restricted area displayed on the color graphic display device 1 of FIG. 1.

In FIG. 2, a plan view 4 of a warning area, that is, a predetermined floor of a building, is displayed on the display screen 1a, and this plan view 4 includes a smoke sensor mark 5a indicating the installation position of the smoke sensor and the installation position of the temperature sensor. Each of the temperature sensor marks 5b indicating the position is graphically displayed.

Referring again to FIG. 1, 40 is a data memory in which detection data detected by an analog fire sensor, such as a smoke sensor or a temperature sensor, installed in the warning area of the fire alarm system is recorded. As will be explained later, the detection data is written to the data memory 40 by polling the analog fire sensors by the fire receiving panel, reading the detection data from multiple sensors sequentially at regular intervals, and reading the sensor data in almost real time. It has gained.

For the data memory 40, there is an address counter 50 which specifies the reading address of the sensor data corresponding to the warning area displayed on the color graphic display device 1.
Address data is given to the address counter 50, and the address counter 50 increments the counter address at every predetermined clock cycle to sequentially read out a plurality of sensor data stored/hidden in the data memory 40.

The sensor data of the caution area sequentially read out from the data memory 40 is given to the section discrimination section 6 and the level discrimination section 7.

Here, the zone determining section 6 determines whether the sensor data given from the data memory 40 is in a predetermined safe zone or in a sensing zone. That is, the safety zone and the sensing zone will be explained as follows with reference to the plan view of the warning zone on the CRT screen shown in FIG.

First of all, safety zones refer to areas where safety must be ensured during evacuation guidance, such as emergency stairwells and surrounding areas in buildings, as well as elevator halls. In the plan view 4 of the figure, each of 81 to Bit is set in advance as a safety zone. On the other hand, the sensing zone refers to a sensor installation location other than the safety zone, and in the plan view 4 of FIG. 2, each zone A1 to A20 is predetermined as a sensing zone.

In addition, the safety zones 81 to 1 in the plan view 4 shown in FIG.
311 shows a smoke sensor mark 5a and a temperature sensor mark 5b, respectively, and in this fire alarm system, safety zones 81 to B11 are important places for evacuation guidance, so the safety zone Both temperature sensors and smoke sensors are installed to properly understand the situation. In addition, in the plan view of Figure 2, not only the staircase room but also
The corridor leading to the staircase has been designated as a safe zone.

Referring again to FIG. 1, the level determination section 7 determines the level of the sensor data continuously output from the data memory 40, and compares the detection level with a plurality of predetermined threshold values to determine which threshold level the detection level is. It determines whether there is a level and outputs a setting signal for a predetermined display color according to the detected level level.

The level discrimination and display color setting by the level discrimination section 7 are as follows:
1, display color settings are determined for each smoke density level.

Table 1 Furthermore, as for the temperature detected by the temperature sensor, as shown in the following Table 2, the setting display color for each detected temperature stage is determined.

Table 2 As is clear from Tables 1 and 2, as the detection level increases for both smoke density and temperature, the display color gradually changes from "cyan" to "yellow" to "magenta".
The color changes from a safe color to a dangerous color, such as "red".

The discrimination output of the section discriminator 6 and the specified display color of the level discriminator 7 are displayed in the sensing section display section 8 and the safe section display section 9, respectively.
given to. When the sensing section display section 8 receives a determination output indicating that the sensor data is a sensing section from the section discriminating section 6, it displays a sensor mark corresponding to the sensor data so that the specified display color given by the level discriminating section 7 is displayed. A display control signal is given to the CRT controller 2 to display the image in color. Further, when the safe zone display section 9 receives the safety zone discrimination output from the zone discriminator 6, it fills out the entire area of the corresponding safety zone and displays it in color so that the designated display color output from the level discriminator 7 is displayed. A display control signal is output to the CRT controller 2 as shown in FIG.

That is, the sensing sections A1 to A20 in the plan view 4 of FIG.
, the smoke sensor mark 5a itself shown in each of the sensing sections A1 to A20 is displayed in color according to the designation of the display color corresponding to the smoke density in Table 1 above. On the other hand, for safety zones 81 to 811, the sensor mark itself is not displayed in color, but the entire area of safety zones 81 to B11 where the sensors are installed is designated according to the detection level in Table 1 or Table 2 above. It will be displayed in color.

In addition, since both smoke sensors and temperature sensors are installed in the safety zones 81 to B11, if the temperature sensor and smoke sensor have different display colors, for example, the display color of the one with the higher degree of danger will be selected. It will now be displayed in color as the specified display color. In addition, safety zones 82 to B4, 87, BIO,
Since the Bll is a corridor serving as an evacuation route, there are no partitions such as walls, so the range of the predetermined safety zone is displayed in designated colors as shown by imaginary lines.

FIG. 3 is a block diagram showing the system configuration of an analog fire alarm facility in which the display device of the present invention shown in FIG. 1 is used.

In FIG. 3, numeral 10 is a fire receiving board, and from the fire receiving board 10, a plurality of signal lines 118 to 1 are directed toward the warning area.
1n is drawn out, and a plurality of smoke sensors 12 and temperature sensors 13 are connected in parallel to each of the signal lines 118 to 11n.

The fire reception board 10 reads detection data from the smoke sensor 12 and temperature sensor 13 by polling control, sequentially writes it into a data memory, and makes a fire judgment based on the sensor data written to the data memory.

A control device 14 used for display control of the display device of the present invention is connected to the fire reception panel 10, and as the control device 14, for example, a microcomputer is used, and the display control of the present invention is executed by program control. . A magnetic disk 15 and a floppy disk 16 are connected to the control device 14 as external storage devices. For example, the magnetic disk 15 permanently stores graphic data for displaying a plan view of the restricted area. Furthermore, the floppy disk 16 stores various types of graphic data that require rewriting. Further, a color graphic display device 1 is connected to the control device 14 via a CRT controller 2, and in this embodiment, various controls by the color graphic display device 1 are all performed using an input method using a C light pen 17. Furthermore, a printer 18 for outputting various data is connected to the control device 14.

Furthermore, the control device 14 has a function of controlling external devices such as fire doors and smoke vents through input operations on the display screen of the color graphic display device 1 using the light pen 17. External control equipment 20a for fire doors, smoke vents, etc.
2On is connected.

Next, display control of the present invention by the control device 14 of FIG. 3 will be explained with reference to the flowchart of FIG. 4.

First, by operating the light pen 17, the display screen of the color graphic display device 1 is used to select and display a plan view of an appropriate warning area. Incidentally, selection and display of the warning area plan is also automatically performed when a fire signal is received from the fire receiving panel 10.

In this selection display, for example, if a plan view 4 as shown in FIG. Then, one of the plurality of sensor data corresponding to the smoke sensor is read out, and the process proceeds to determination block 32, where it is determined whether the read sensor data is in the safety zone or the sensing zone.

If the sensor data is in the safe zone, the process proceeds to block 34, and if it is smoke concentration data from a smoke sensor, a display color is set according to the smoke concentration according to the discrimination criteria in Table 1 above, and the safety zone corresponding to the sensor data is set. The section B1 is displayed in color so as to be filled with the set display color.

On the other hand, if the sensor data is a sensing section, the process proceeds to block 36, and if the sensor data is smoke density, for example, a display color corresponding to the smoke density according to the discrimination criteria in Table 1 is specified and a corresponding response is performed. The sensor mark itself of the sensing section is displayed in color at the designated display port.

Similarly, the sensor data of the displayed plan view is sequentially read out, and color display is performed based on the determination of the safety zone and the sensing zone.

As a result, in the plan view 4 of FIG. 2, the sensing section A1
~ Regarding the sensor mark shown in A20, that is, smoke sensor mark 5, the detection level of each sensor, that is, the above table -
It is now displayed in color according to the smoke concentration of No. 1, and by looking at the display color of the sensor marks in the sensing sections A1 to A20, it is possible to easily and easily grasp the status of smoke concentration in the sensing sections. . On the other hand, safety zones 81-811
, by setting the display color for the smoke latitude and temperature shown in Table 1 or Table 2, whichever is more dangerous, the safe area will be completely wiped out and displayed in color. , the color display areas of the safety zones 81 to B11 are sufficiently large, so the status of the safety zones can be easily and easily grasped by looking at the display colors of the safety zones 81 to B11.

In particular, when a fire occurs, for example, if a fire breaks out in the sensing section A1, the sensor mark of the sensing section A1 will be displayed in red, for example, and the sensor marks of the nearby sensing sections A2 and A3 will be displayed in red. For example, safety zones 81 and 82, which are in the vicinity of the sensing zone A1 where the fire occurred, will be displayed in "red" or "magenta" color, which indicates a high degree of danger; Safety area 8 away from A1
5 to 311 are displayed in cyan, which is the safe color. By looking at the stepwise color display of these safe zones, the operator can immediately determine the safe evacuation route and provide appropriate evacuation guidance. can be instructed. Additionally, if a fire spreads, the sensor mark for the sensing compartment and the display color for the entire safety compartment will change in real time to a high-risk display color depending on the smoke concentration and/or temperature. By monitoring not only the color display of the sensor mark but also changes in the color display of the safety zone, it is possible to appropriately instruct changes in evacuation routes due to the spread of the fire.

Note that the safety zone and sensor mark may be displayed in different colors. For example, the safety zone may be displayed in three different colors. That is, "cyan" at less than 10%/m, 10-20%/m
m is defined as "magenta", and 20%/m or more is defined as "red".

In addition, the color display of the safe area is based on the smoke concentration sensor)
It is also possible to do this based only on the agricultural rate.

(Effects of the Invention) As described above, according to the present invention, a plurality of analog fire sensors that output signals according to changes in physical phenomena associated with fire are installed in a warning area, and In a fire alarm system in which a fire is determined by a fire receiving panel based on the detection signal of Furthermore, the warning area floor plan is divided into safe areas and sensing areas, and the sensor data of the monitoring area is sequentially read in, display colors are set in stages according to the detection level, and when the sensor data is in the sensing area, the corresponding sensor mark is displayed. itself is displayed in the set display color, and when the sensor data indicates a safe zone, the entire corresponding safe zone is displayed in color so that the entire corresponding safe zone is filled in with the set display color. Of course, when making a fire judgment, the sensor mark in the sensing compartment will turn red or other dangerous colors, allowing you to know the location of the fire and the surrounding situation. Since the display is displayed in color according to the smoke concentration and detected temperature, the color display of the sensor mark and the color display of the safety zone can be used to give appropriate instructions for firefighting and evacuation guidance, thereby preventing the spread of a fire. Since accompanying changes in the situation can be grasped sequentially by switching the color display, prompt firefighting instructions and appropriate evacuation guidance instructions can be given quickly and without error.
