Data is stored, and in this embodiment, for example, the data of the analog value detected by the fire detectors 10 and 11 is divided into 64 stages of 00 to 32 to 64, and the data of the 64 stages is stored. Stores the shade data of the color for. Then, the stored grayscale data is used as a color of the background of the monitoring section of the fire detectors 10 and 11 displayed on the screen 32.

Here, if the intermediate color is set so that the gradation data of the color is gradation from light to dark of one color, it is easy to perceptually recognize the darkness or high temperature of smoke. And
By setting different shades of color for each type of analog fire detector, it is possible to identify smoke and heat changes separately during a fire and accurately understand the spread of the fire. can do.

Next, the data flow of this embodiment will be described. FIG. 2 is an explanatory diagram for explaining the data flow of this embodiment. First, the fire detector 10,1
1 has an individual address 50, and the analog value data 51 of the information detected by the fire detectors 10 and 11 is output to the fire receiver 20 together with the address 50. Then, the data input to the fire receiver 20 is subjected to the fire discrimination processing 60 based on the information stored in the data storage unit 24 to generate the terminal state data 52 of the terminal devices such as the fire detectors 10 and 11. Address 5
0, analog value data 51 and terminal status data 52 are C
It is output to the RT board 30.

Each piece of data input to the CRT board 30 is subjected to a sensing section discrimination 61 from the address 50 based on the information stored in the display data storage section 35 to generate the area shape data 53. , The background color discrimination 62 is performed from the analog value data 51 and the background color data 5
4 is generated, the symbol color discrimination 63 is performed from the terminal state data 52, and the symbol color data 55 is generated. And these district shape data 53 and background color data 54
The symbol color data 55 is used as display data for the screen 32.

Next, the display of the screen 32 of this embodiment will be described. FIG. 3 is an explanatory diagram for explaining an example of the display of the screen 32 of this embodiment. In the figure, 7
Reference numerals 0 and 71 are symbols of the fire detector, 70 indicates the heat detector 10, and 71 indicates the smoke detector 11.
Reference numeral 72 denotes a detection section of the fire detectors 10 and 11, and the display color of the detection section 72 changes based on the background color data 54 corresponding to the above-described detection section. Also,
The numbers near the symbol displays 70 and 71 indicate the numbers of the sections.

As shown in FIG. 3, the fire detectors 10 and 11 are shown.
Symbol displays 70, 71 of the fire detector 10 and 71 indicate information such as normal times and fires, and display 7 of the detection section of the fire detectors 10, 11.
2 has its color continuously changed based on the analog value data detected by the fire detectors 10 and 11.

The changes in the symbol displays 70 and 71 are as follows.
As shown in FIG. 3, for example, it is lit in white during normal operation, blinks in yellow during a pre-alarm, blinks in red during a fire, and blinks in white during a failure. As the background color change, different shades of color are displayed for each type based on the analog value data. Further, as shown in FIG. 3, for example, in the case of the compartment display of the smoke sensor 11,
Dark green when the density of smoke detected by the sensor is less than 3% / m, dark yellow when 5% / m, dark red when 10% / m, dark when the maximum smoke sensor density is detected. As in the case of magenta, the color may be continuously changed by using an intermediate color within a range in which the contrast between the color of the symbol display and the partition color of the sensing section can be obtained.

Instead of changing the color of the entire section display 72, the colors in the vicinity of the symbol displays 70 and 71 may be left as normal colors and the other colors may be changed. In this case, when the colors of the symbol displays 70 and 71 are changed, they do not overlap with the colors in the section display.

Further, as shown in FIG. 4, the background color of the detection section of the fire detectors 10 and 11 is set so that the color of only the section near the section line of the section display 72 is changed, not the entire section display 72. Good.

Next, the multimedia function of the TV tuner 39 and ITV unit 38 of the CRT board 30 will be described. On the CRT board 30, the screen 32 shows I of the fire district.
Images from the TV camera 37 and emergency broadcasts from the TV tuner 39 when a disaster occurs due to an earthquake or the like can be displayed. Further, the switching of these screens is controlled by the display processing unit 31 based on the input from the repeating unit 34, or the display processing unit 31 is used for emergency broadcasts.
Is automatically displayed on the screen 32.

This emergency broadcast is broadcast by a television station (necessarily performed by NHK), for example, when a large earthquake occurs, and the display processing unit 31 receives the emergency broadcast via the TV tuner 39. When it detects, the image from the TV tuner 39 is automatically displayed on the screen 32 to display the emergency broadcast, and the building supervisor who has watched the broadcast operates the looping section 34 to display the emergency broadcast. Whether or not a fire has occurred, the analog value detected by the analog fire detectors 10 and 11 can be confirmed, and whether or not there is an abnormality in the building can be confirmed by searching the image of the ITV camera 37. It is like this. The ITV camera 37 may be a normal television camera, and the ITV unit 38 performs switching control in response to an input from the operation unit 34 of the CRT board 30 to retrieve each image.

In this embodiment, the background color of the detection section display of each of the fire detectors 10 and 11 displayed on the screen 32 is continuously determined based on the analog value data detected by each of the fire detectors 10 and 11. Since it is changed, it becomes possible to confirm the intermediate state that can not be expressed only by the judgment display such as fire and forecast, it is easy to visually recognize the dangerous zone and the safe zone, and grasp the spread situation of the fire Therefore, it is possible to perform appropriate fire fighting and evacuation guidance.

Further, in this embodiment, the fire receiver 20
Although the CRT panel 30 and the CRT panel 30 are shown as separate units,
It may be configured integrally, for example, the display operation unit 23 on the board surface.
The CRT board 30 may be unitized and replaced.
