Abstract

PROBLEM TO BE SOLVED: To unnecessitate a picture display instruction data base to be frequently changed, and to eliminate conventionally required change work by displaying data at positions on a plan view corresponding to the address rows and columns of data signals with addresses. SOLUTION: When a main controller and human interface receives display data 1, first of all, a fixed face corresponding to an alarm zone 01 of address part in the display data 1 is taken out of a fixed face data base and displayed. Next, the contents of data are displayed at sensor install positions corresponding to the row and column of address parts on the plan view inside the relevant alarm zone while using a prescribed symbol. Thus, the alarm zone and the address inside that zone are inputted to the address part of display data 1 while using the numbers of row and column so that the data can be displayed according to these row and column. Thus, the picture display instruction data base is unnecessitated and even when the sensor install positions are moved or increased/decreased, the display on a CRT screen can be changed even without changing the data base of picture information.

Reference numeral 2 denotes one caution area as an example of a CRT screen display. In the present invention, a rectangle circumscribing one guard area is assumed, and is divided into rows and columns. The maximum number of rows and columns is 10 (0 to 9), and corresponds to the rows and columns of the address portion of the display data 1. In the above guard area, rows and columns are (1, 2) respectively.
(3, 3) It is assumed that a sensor is installed at the position of (2, 6).

Next, the operation will be described with reference to the flowchart of FIG. When the main controller / human interface 60 receives the display data 1, first, a fixed image corresponding to the guard zone (01) in the address portion of the display data 1 is extracted from the fixed image database and displayed. Next, the data content is displayed using a predetermined symbol at the sensor installation position corresponding to the row and column of the address section on the plan view of the corresponding guard area. The display screen is 2 in FIG.

As described above, in the first embodiment, the display area is displayed in accordance with the row and the column by putting the guard area and the address therein in the address portion of the display data by the numbers of the row and column positions. The screen display instruction database is unnecessary, even if the sensor installation position moves, increases / decreases, etc., without changing the screen information database.

Next, the operation will be described. As shown in FIG. 3, on the CRT screen, the guard area in the plan view of the building is displayed as a fixed image based on the contents of the fixed image database, and according to the address added to the display data sent from the disaster prevention receiver. The row of the sensor installation location in the relevant security zone,
The sensed temperature information (65, 80, 150) is displayed at the row position. As described above, in the present embodiment, not only the presence or absence of a fire and its occurrence position, but also the strength of the fire (the height of the sensed temperature) can be known in detail, which is effective for grasping the state of fire spread.

Embodiment 3 Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. In general, it is considered that the temperature at a certain point changes according to the distance with respect to the ignition point as the center, as shown in Expression (1).

Assuming that the sensor installation position (1, 2) (3, 3) (2, 6) is the ignition point, and creating the ambient temperature distribution according to the equation (1), FIG. 5 (a) (b) (c) Such a temperature distribution is obtained. That is, assuming that the ignition point temperature of the sensor of (1, 2) is 65 degrees, the temperature distribution around the sensor is as shown in (a).
Similarly, when the ignition temperature of the sensor of (3, 3) is set to 80 degrees, the temperature distribution around the sensor becomes as shown in (b). Similarly, assuming that the ignition temperature of the sensor (2, 6) is 150 degrees, the temperature distribution around the sensor is as shown in (c). 3 above
Assuming that three sensors are the ignition points, the temperature distribution of the three sensors is complemented by adding the temperature distribution of the three sensors for each row and column, as shown in (d). , The temperature distribution can be displayed. Therefore,
By performing the above processing in the main controller / human interface 60, it is possible to calculate the temperature distribution of the entire alert area including the place where the sensor is not installed, and to display the spread of the fire and the temperature distribution as numerical values on the CRT. It should be noted that the numerical values in FIG. 5 are examples and are not calculated properly.

This operation will be described with reference to the flowcharts of FIGS. First, for example, it is assumed that the fixed image data coordinates (0, 0) shown in FIG.
Is compared with the temperature distribution of FIG. 3 (that is, the distribution of 65, 80, and 150). At this position, the temperature of the firing point is changed from room temperature to T1 (T1 is a constant) at intervals of 1 degree, and pattern matching is checked. If the temperature distribution patterns match, (0, 0) is the firing point, and the temperature at that time is determined to be the firing temperature. If there is no pattern match, then the same is repeated, assuming that the coordinates (0, 1) are the firing point. Such an operation is performed up to the coordinates (9, 9), and a point having the smallest difference in the pattern comparison is determined as a fire point. In the case of FIG. 6, when the temperature of the coordinates (2, 6) is 150 degrees, the coordinates (1,
Since 2) has a temperature distribution of 65 degrees and coordinates (3, 3) have a temperature distribution of 80 degrees, the coordinates (2, 6) are determined as the fire point and 150 degrees is determined as the fire temperature, and displayed on the CRT. As described above, in the fifth embodiment, a fire point in the caution area can be assumed,
Fire spread prevention and evacuation guidance can be performed efficiently.
