And the red circle drawn in this way shows the area where the fire broke out, and the red line shows the area where the fire broke out and spread (see FIG. 6). A user of the fire area information 32 can acquire the fire area information 32 via a network such as the Internet and an intranet, television broadcasting, or the like.
For this reason, the user of the fire area information 32 can grasp | ascertain sequentially the area where the fire broke out within one area, and the fire spread area. Therefore, grasp the situation of a fire spread from a large amount of highly reliable information, determine the direction of residents in the fire area to evacuate and priority fire extinguishing areas, and minimize the damage caused by the fire spread. Can do.

In addition, the fire information processing device 30 is a fire area obtained by information processing of the fire progress information 55 and the map information 52 obtained by detecting that the continuously transmitted notification signal 20a is stopped. Information 32 is transmitted.
The fire area information 32 is, for example, information in which a gray circle is drawn at the coordinates of the map corresponding to the area code accompanied by the notification signal 20a whose transmission is stopped with respect to the map stored in the map information 52. . Further, when there are a plurality of notification signals 20a whose transmission is stopped, a map corresponding to the area code accompanied by the notification signals 20a whose transmissions are stopped with respect to the map stored in the map information 52. This is information in which a gray straight line connecting close coordinates is drawn. The gray circle drawn as described above indicates an already burned-out area, and the gray straight line indicates an area that has already been burned-out (see FIG. 6).
For this reason, the user of the fire area information 32 can grasp | ascertain sequentially the area and area which have already burned down in one area in addition to the information of the area and area where the fire occurred in one area.
Therefore, grasp the situation of a fire spread from a large amount of highly reliable information, determine the direction of residents in the fire area to evacuate and priority fire extinguishing areas, and minimize the damage caused by the fire spread. Can do.

The fire information processing apparatus 30 has a plurality of fire occurrence information 54 obtained by detecting a plurality of notification signals 20a transmitted continuously and / or a plurality of notification signals 20a transmitted continuously. Fire degree speed information 33 obtained by processing a plurality of fire progress information 55 obtained by detecting the stop is transmitted. A user of the fire speed information 33 can acquire the fire speed information 33 via a network such as the Internet, a television broadcast, or the like.
For this reason, the user of the fire area information 32 can grasp | ascertain sequentially the fire occurrence speed and speed, ie, a fire spread rate.
Therefore, it is possible to grasp the situation of the fire spread from the viewpoint of the fire spread speed, determine the direction in which the residents in the fire area evacuate and the priority fire extinguishing area, and further minimize the damage caused by the fire spread.

The fire occurrence signal transmission device 10 and the notification signal transmission device 20 are arranged in one area such as one city. The map information 52 stores map image data in the area.
For this reason, the fire information processing apparatus 30 transmits the fire area information 32 and the fire speed information 33 in the one area.
Therefore, the user of the fire area information 32 grasps the situation of the fire spread in the area, judges the direction of the refuge of the fire area in the area and the priority fire extinguishing area, and damages due to the fire spread. Can be kept to a minimum.

  The fire occurrence signal transmitting device 10 is a device that emits a fire alarm sound (alarm buzzer sound) that is a fire occurrence signal 10a when detecting smoke generated by a fire, and is disposed in a house, a public facility, or the like. For this reason, a fire alarm or the like already installed in a building or the like can be used as the fire occurrence signal transmission device 10. Therefore, the fire spread monitoring system 1 according to the present invention can be realized at low cost.

The fire generation signal transmission device 10 is not limited to detecting smoke generated by a fire, and may be a case of detecting a flame at a predetermined temperature.
The fire occurrence signal 10a is not limited to a fire alarm sound of an alarm buzzer sound, and may be an electric signal or a sound fire alarm sound.
If the fire signal 10a is an electrical signal and the alarm signal detector 41 is configured to detect the electrical signal, the alarm signal 10a may be erroneously detected by the alarm signal detector 41. The number of fires can be ascertained from more reliable information.

The fire occurrence signal transmission device 10 and the notification signal transmission device 20 are not particularly limited to being arranged separately. That is, the fire occurrence signal transmission device 10 and the notification signal transmission device 20 may be configured as a single device including both devices.
With this configuration, it is not necessary to newly provide a space for arranging the alarm signal transmitter 20. Moreover, the alarm signal transmitter 20 is also disposed at the same time as the fire occurrence signal transmitter 10 is disposed. For this reason, it becomes possible to arrange the alarm signal transmitters 20 easily and inexpensively, and an increase in the number of alarm signal transmitters 20 can be expected.
Therefore, it is possible to grasp the situation of a fire spread from a larger amount and more reliable information, judge the direction of the residents in the fire area and the priority fire extinguishing area, and minimize the damage caused by the fire spread.

A plurality of fire information processing apparatuses 30 are arranged in one area or outside one area, and the plurality of fire information processing apparatuses 30 are connected to each other via a network such as the Internet.
For this reason, for example, even when one fire information processing apparatus 30 becomes unable to move due to a wide-area disaster, the fire area information 32 can be transmitted by another fire information processing apparatus 30. Therefore, even when such a wide-area disaster occurs, damage caused by a fire spread can be kept to a minimum.
However, the fire information processing apparatus 30 is not particularly limited to being arranged in a plurality, and only one fire information processing apparatus 30 may be arranged.

When the fire area information transmission unit 42 described above creates the fire area information 32, the red straight line and the gray line connecting the two close coordinates on the map can be replaced with arrows. . For example, in the case where two neighboring area codes are stored among the two or more area codes stored in the fire occurrence information 54, and the detection date and time of the notification signal 20a accompanied with the two area codes are different, the detection is performed. A red or gray arrow is drawn from the coordinates on the map indicated by the earlier area code to the coordinates on the map indicated by the later detected area code.
Thus, by drawing an arrow on the map for two coordinates with different detection dates and times, it is possible to grasp the direction in which the fire spreads. For this reason, it is possible to determine the direction in which the residents in the fire area evacuate in the area and the priority fire extinguishing area, and to minimize the damage caused by the fire.

The alarm signal transmitter 20 can also be configured to detect an emergency signal other than the fire occurrence signal 10a. For example, emergency call devices for informing the emergency state when the elderly at home or the physically handicapped are in poor health, etc., and crime prevention devices (infrared detectors, window and door open / close detectors installed in buildings) Etc.) is configured to detect an emergency signal transmitted from.
In the case where the notification signal transmission device 20 is configured as described above, in addition to being able to minimize the damage caused by a fire spread, a nursing support function within the one area can be obtained from a large amount of highly reliable information. The crime prevention function can be improved. In addition, it is possible to realize a home care emergency notification system, a building crime prevention system, and the like at low cost by diverting the notification signal transmission device 20 already installed in a building or the like.
