When the disaster is a fire, the first determination unit 303 determines that a fire state, a fire possibility state, a fire unknown state, or a normal state is used as a classification of the possibility that a fire has occurred. The fire state is a state in which there is an extremely high possibility that a fire has occurred. The fire possibility state is a state in which there is a high possibility that a fire has occurred, although it is not as high as the fire state. Further, the unknown fire state is a state in which fire information cannot be obtained from the fire detector 20 or the composite sensor 10 due to a failure.

Specified in the compartment sensor information. The first determination unit 303 determines that the section associated with the identification information of the fire detector 20 specified in the section sensor information is in a fire unknown state in which it is unknown whether or not a fire has occurred.

It is specified in the compartment sensor information stored in. The first determination unit 303 determines that the section associated with the identification information of the composite sensor 10 specified in the section sensor information is in a fire state.
Further, when the first determination unit 303 determines that the temperature detection result is a temperature equal to or lower than a predetermined threshold value, the temperature rise rate indicated by the temperature detection result exceeds the predetermined threshold value. Determine if it exists.
When the first determination unit 303 determines that the temperature detection result has an increase rate exceeding a predetermined threshold value, the storage unit 301 stores the identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. It is specified in the compartment sensor information to be stored. The first determination unit 303 determines that the section associated with the identification information of the composite sensor 10 specified in the section sensor information is a fire possibility state.
Further, when the first determination unit 303 determines that the temperature detection result has an increase rate equal to or less than a predetermined threshold value, the first determination unit 303 stores identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. It is specified in the compartment sensor information stored in 301. The first determination unit 303 determines that the partition associated with the identification information of the composite sensor 10 specified in the partition sensor information is in the normal state.

The identification information to be specified is specified in the partition sensor information stored in the storage unit 301. The first determination unit 303 determines that the section associated with the identification information of the composite sensor 10 specified in the section sensor information is in a fire unknown state.

Specifically, for example, when the disaster is a fire, the first determination unit 303 receives the smoke detection result acquired by each composite sensor 10 from the data collection unit 302. The first determination unit 303 determines whether or not the smoke detection result detects smoke with respect to the detection result acquired by each composite sensor 10.

The first determination unit 303 determines that the section associated with the identification information of the composite sensor 10 specified in the section sensor information is in a fire unknown state.

When there are a plurality of determination results, the first determination unit 303 determines that the state with the highest possibility of a fire among the states indicated by the determination results is the state of the section.

The disaster occurrence determination unit 304 determines whether or not there is a high possibility of a disaster occurring in each section.
Specifically, for example, the disaster occurrence determination unit 304 determines whether or not each section is in a fire state.
Then, the disaster occurrence determination unit 304 identifies the section in a fire state as a section having a high possibility of a disaster.

The second judgment unit 305 describes the section in the unknown fire state based on the connection relationship between the section determined by the disaster occurrence judgment unit 304 in the fire state and the section in the unknown fire state (the section in which the sensor is out of order). Judge the possibility of a disaster.

Specifically, for example, when the second judgment unit 305 is adjacent to the section in the fire state and is in contact with the ceiling or wall of the section in the fire state, the second judgment unit 305 is as fired as the possibility of fire. Although it is not highly likely that a fire has occurred, the section with the highest possibility of a fire and the section with an unknown fire are determined as the sections with an unknown fire. The term “adjacent” here includes not only those that are in contact with each other on a surface but also those that are in contact with each other by a line or a point. For example, the compartment B7 shown in FIG. 2 is adjacent to each of the compartments A7, B3, B6, B8, B11, and C7 in terms of surface. Further, the compartment B7 is adjacent to each of the compartments A3, A6, A11, B2, B4, B10, B12, C3, C6 and C11 by a line. Further, the compartment B7 is adjacent to each of the compartments A2, A10, C2, and C10 in terms of points. Further, in the second judgment unit 305, when the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the ceiling of the section in the fire state with a line or a point, the fire is occurring as much as the possibility of fire. Although the possibility is not high, the section with the second highest possibility of having a fire and the section with unknown fire are determined as the sections with unknown fire. Further, in the second judgment unit 305, the section in the fire unknown state is adjacent to the section in the fire state and is on the same deck of the section in the fire state (that is, the section in the fire unknown state X is adjacent to the section in the fire state and its deck). If it is on the same floor as the section in the fire state) and is in contact with the wall with a line, it is not as likely that a fire has occurred as in the possibility of fire, but a fire has occurred in the section in the unknown fire state X. Determine which compartment is the third most likely to be and which is in an unknown fire condition. In addition, if the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state, the second judgment unit 305 may have a fire as much as the possibility of fire. Is not high, but the section with the fourth highest possibility of a fire occurring as the section with the unknown fire state X and the section with the unknown fire state are determined. Further, in the second judgment unit 305, when the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state with a line or a point, the fire is occurring as much as the possibility of fire. Although the possibility is not high, the section with the fifth highest possibility of having a fire and the section with unknown fire are determined as the sections with unknown fire. In addition, the second judgment unit 305 indicates that if the section in the unknown fire state does not touch the section in the fire state, the possibility that a fire has occurred is not as low as in the normal state, but the fire may have occurred rather than the state. Judge the section with low sex and the section with unknown fire.
Specifically, for example, when the section in the unknown fire state is in contact with a plurality of sections in the fire state by a surface, a line or a point, the second judgment unit 305 can fire the section in the unknown fire state. Judged as a sex zone.
It should be noted that the determination of the fire possibility section is based on the fact that when a fire occurs, the flame easily moves from the bottom to the top, and the wider the ground contact area, the easier the flame spreads.

Specifically, for example, when a section changes from a normal state to a fire unknown state, the second determination unit 305 supplies power to the composite sensor 10 or the fire detector 20 of the section from the power supply device. The section of the fire unknown state X through which the electric wire passes is determined to be the section of the fire possibility state.
More specifically, for example, a compartment A in which the electric wire A feeding the composite sensor 10 or the fire detector 20 from the power feeding device shown in FIG. 4 is guided, a compartment B in which the electric wire B is guided, and the like. The information is stored in the storage unit 301 in advance. As shown in FIG. 4, the electric wire B that supplies power from the power supply device to the composite sensor 10 or the fire detector 20 in the compartment B passes through the compartment A, the compartment A is in an unknown fire state, and the compartment B is in a normal state. Suppose that In such a state, when the section B changes from the normal state to the fire unknown state, the second determination unit 305 determines that the section through which the electric wire B passes is a section in a fire possibility state.
In the determination of the fire possibility section, the compound sensor 10 or the fire detector 20 in the section B suddenly changes from the normal state to the unknown state because the section A is in the fire state and the electric wire B is burnt. It is based on the high possibility that.

Further, specifically, for example, in the second judgment unit 305, the section in the fire unknown state is in the fire state through the ventilation duct of the same route (even if the route of the ventilation duct is branched, it is regarded as the same). If it is connected to a section, the section in the unknown fire state is determined to be a section in the possibility of fire.
The determination of the fire possibility section is based on the high possibility that the flame spreads through the ventilation duct of the same route.

In addition, the order of the possibility that a fire has occurred as the above-mentioned section in the unknown state of fire is an example, and the second judgment unit 305 is based on the material of the ceiling, wall, floor, deck and other conditions. , The order may be changed. In addition, the second judgment unit 305 raises the rank as the ground contact area is wide or the length of the ground wire is long when the section in the fire unknown state is adjacent to a plurality of fire states. It may be.

The third determination unit 306 is a section determined to have a high possibility of disaster (that is, a section determined by the disaster occurrence determination unit 304 to be in a fire state) and a section determined to have a low possibility of disaster (that is, a section). Based on the connection relationship between the judgment result indicating the normal state and the judgment result indicating the disaster unknown state for the same section), the disaster occurrence possibility is judged for the section judged to have a low disaster occurrence possibility. ..
Specifically, when the disaster is a fire, the third judgment unit 306 determines the possibility of a fire in the section determined to have a low possibility of fire based on the connection relationship with the section in a fire state. To do.

More specifically, for example, in the third determination unit 306, when the section determined to have a low possibility of fire is adjacent to the section in the fire state and is in contact with the ceiling or wall of the section in the fire state. Although the possibility of a fire is not as high as the possibility of fire, the section with the highest possibility of a fire and the section with the highest possibility of a fire are considered to have a low possibility of a fire. Judge the section judged to be low in character. Further, in the third judgment unit 306, when the section determined to have a low possibility of fire is adjacent to the section in the fire state and is in contact with the ceiling of the section in the fire state by a line or a point, the fire possibility state is increased. Although the possibility of a fire is not high, the section with the second highest possibility of a fire as the section judged to have a low possibility of a fire and the section with the lowest possibility of a fire Determine the determined compartment. In addition, the third judgment unit 306 can fire if the section judged to have a low possibility of fire is adjacent to the section in the fire state and is on the same deck of the section in the fire state and is in contact with the wall with a line. It is not as likely that a fire is occurring as in the sexual state, but the area that is judged to have a low possibility of fire and the area that is the third most likely to have a fire and the possibility of fire. Judges the section judged to be low. Further, in the third judgment unit 306, when the section determined to have a low possibility of fire is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state, the fire is as high as the possibility of fire. Although the possibility of a fire is not high, it is judged that the section with the fourth highest possibility of a fire as a section judged to have a low possibility of fire and the section with a low possibility of a fire. Judge the section. Further, in the third determination unit 306, when the section determined to have a low possibility of fire is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state with a line or a point, the fire possibility state is increased. Although the possibility of a fire is not high, it is said that the section with the fifth highest possibility of a fire and the section with a low possibility of a fire are the sections judged to have a low possibility of a fire. Determine the determined partition.

The above-mentioned ranking of the possibility of a fire occurring as a section judged to have a low possibility of a fire is an example, and the third judgment unit 306 includes materials for ceilings, walls, floors, decks, and the like. The order may be changed based on the conditions of. Further, when the section determined to have a low possibility of fire is adjacent to a plurality of sections in a fire state, the third determination unit 306 determines that the ground contact area is wide or the length of the ground line is long. It may be the one that raises the rank.

The priority order specifying unit 307 specifies the priority of the section to perform a predetermined measure based on the possibility of disaster occurrence.
Specifically, for example, the priority specifying unit 307 extinguishes a fire in the order of high possibility of disaster occurrence indicated by the respective judgment results by the first judgment unit 303, the second judgment unit 305, and the third judgment unit 306. Increase the priority.

The presentation control unit 308 causes the presentation unit to present a section for performing a predetermined action with the priority specified by the priority specification unit 307.
Specifically, for example, a presentation unit is provided in the composite sensor 10, and the priority is presented to a plurality of presentation units together with a section that needs to extinguish a fire.

Next, the processing of the disaster zone identification system 1 according to the embodiment of the present invention will be described.

When the rate of increase is equal to or less than the threshold value, the identification information that matches the identification information of the composite sensor 10 that has acquired the detection result is specified in the partition sensor information stored in the storage unit 301. The first determination unit 303 determines that the section associated with the identification information of the composite sensor 10 specified in the section sensor information is the section of A (see FIG. 6) having a low possibility of fire.
Further, since the first determination unit 303 has a plurality of determination results for each section, the state indicated by the determination result based on the detection result of the composite sensor 10 and the state indicated by the determination result based on the detection result of the fire detector 20. When both are in the unknown fire state, the section is determined to be the section in the unknown fire state X (see FIG. 6). For example, the first determination unit 303 determines that the composite sensor 10 for which data has not been acquired is out of order. Further, for example, the first determination unit 303 determines that the fire detector 20 has failed when the failure signal is acquired.
Further, since the first determination unit 303 has a plurality of determination results for each section, the state indicated by the determination result based on the detection result of the composite sensor 10 and the state indicated by the determination result based on the detection result of the fire detector 20. When both are in a normal state, it is determined that the section is a section in a state B (see FIG. 6) in which the possibility of a fire occurrence section is extremely low.

The disaster occurrence determination unit 304 determines whether or not there is a high possibility of a disaster occurring in each section. For example, the disaster occurrence determination unit 304 determines whether or not each section is in a fire state.
Then, the disaster occurrence determination unit 304 identifies the section in the fire state SS as the section having a high possibility of disaster occurrence (step S3). The disaster occurrence determination unit 304 outputs the determination result to the second determination unit 305 and the third determination unit 306.

The second determination unit 305 receives the determination result from the disaster occurrence determination unit 304. The second determination unit 305 has a fire unknown state X based on the connection relationship between the section determined by the disaster occurrence determination unit 304 to be in the fire state SS and the section in the fire unknown state X (the section in which the sensor has failed). The possibility of a disaster occurring in the section of (step S4) is determined.

Specifically, for example, in the second determination unit 305, when a certain section changes from a normal state to a fire unknown state, an electric wire that supplies power from the power feeding device to the composite sensor 10 or the fire detector 20 in the certain section It is determined that the section of the fire unknown state X passing through is the section of the fire possibility state.
More specifically, for example, a compartment A in which the electric wire A feeding the composite sensor 10 or the fire detector 20 from the power feeding device shown in FIG. 4 is guided, a compartment B in which the electric wire B is guided, and the like. The information is stored in the storage unit 301 in advance. As shown in FIG. 4, the electric wire B that supplies power from the power supply device to the composite sensor 10 or the fire detector 20 in the compartment B passes through the compartment A, the compartment A is in an unknown fire state, and the compartment B is in a normal state. Suppose that In such a state, when the section B changes from the normal state to the fire unknown state, the second determination unit 305 determines that the section through which the electric wire B passes is the section in the fire possibility state S2.

Specifically, for example, when the section of the fire unknown state X is in contact with a plurality of sections of the fire state by a surface, a line or a point, the second determination unit 305 determines the section of the fire unknown state X. It is determined that the section is in the fire possibility state S2.

Further, specifically, for example, in the second determination unit 305, the section of the fire unknown state X is considered to be the same through the ventilation duct of the same route (even if the route of the ventilation duct is branched, it is regarded as the same). When connected to the section of, the section in the unknown fire state is determined to be the section in the fire possibility state S2.

In addition, the order of the possibility that a fire has occurred as the above-mentioned section in the unknown state of fire is an example, and the second judgment unit 305 is based on the material of the ceiling, wall, floor, deck and other conditions. , The order may be changed. In addition, the second judgment unit 305 raises the rank as the ground contact area is wide or the length of the ground wire is long when the section in the fire unknown state is adjacent to a plurality of fire states. It may be.

Specifically, for example, when the section of the fire unknown state X is in contact with a plurality of sections of the fire state by a surface, a line or a point, the second judgment unit 305 may fire the section of the state A. Judge as a section.

Further, specifically, for example, in the second determination unit 305, the section of the fire unknown state X is considered to be the same through the ventilation duct of the same route (even if the route of the ventilation duct is branched, it is regarded as the same). If it is connected to the section of, the section of the state A is determined to be a fire possibility section.

In addition, the second judgment unit 305 may cause a fire in the section in the unknown fire state X based on whether the section in the unknown fire state X touches the adjacent section with a surface, a line, or a point when the above conditions are not met. To judge.
Specifically, for example, the second determination unit 305 may have a fire possibility when the section of the fire unknown state X is adjacent to the section of the fire state SS and is in contact with the ceiling or wall of the section of the fire state SS. It is not as likely that a fire has occurred as in state A, but it is most likely that a fire has occurred as a section of fire unknown state X. The section of state X1-1 (see FIG. 6) and the state of unknown fire. Judge the division of. Further, in the second judgment unit 305, when the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the ceiling of the section in the fire state with a line or a point, the fire is occurring as much as the possibility of fire. Although the possibility is not high, the section of the state X1-2 (see FIG. 6) and the section of the unknown fire state, which are the second most likely to have a fire, are determined as the sections of the unknown fire state. Further, in the second judgment unit 305, the section in the fire unknown state is adjacent to the section in the fire state and is on the same deck of the section in the fire state (that is, the section in the fire unknown state X is adjacent to the section in the fire state and its deck). If it is on the same floor as the section in the fire state) and is in contact with the wall with a line, it is not as likely that a fire has occurred as in the possibility of fire, but a fire has occurred in the section in the unknown fire state X. The section of the state X1-3 (see FIG. 6) and the section of the unknown fire state, which are the third most likely to be in the fire state, are determined. In addition, if the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state, the second judgment unit 305 may have a fire as much as the possibility of fire. Is not high, but the section of the state X1-4 (see FIG. 6) and the section of the unknown fire state, which are the fourth most likely to have a fire, are determined as the section of the unknown fire state X. In addition, in the second judgment unit 305, when the section in the unknown fire state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state with a line or a point, a fire has occurred as much as the possibility of fire. Although the possibility is not high, the section of the state X1-5 (see FIG. 6) and the section of the unknown fire state, which are the fifth most likely to have a fire, are determined as the sections of the unknown fire state. In addition, the second judgment unit 305 indicates that if the section in the unknown fire state does not touch the section in the fire state, the possibility that a fire has occurred is not as low as in the normal state, but the fire may have occurred rather than the state. Judge the section with low sex and the section with unknown fire.
In addition, the second judgment unit 305 indicates that if the section in the unknown fire state does not touch the section in the fire state, the possibility that a fire has occurred is not as low as in the normal state, but the fire may have occurred rather than the state. A section having a low property X2 (see FIG. 6) and a section having an unknown fire are determined.

Next, the third judgment unit 306 determines that the section of the state SS determined to have a high possibility of fire occurrence (that is, the section determined by the disaster occurrence determination unit 304 to be in a fire state) and the section of which the possibility of disaster occurrence is low. Based on the connection relationship between the determined state A section (that is, the section having the determination result indicating the normal state and the determination result indicating the disaster unknown state X for the same section), it was determined that the possibility of fire occurrence is low. The possibility of a disaster occurring in the section of the state A is determined (step S5).

More specifically, for example, the third determination unit 306 is in a fire possibility state when the section of the state A is adjacent to the section of the fire state SS and is in contact with the ceiling or wall of the section of the fire state SS. Although the possibility that a fire has occurred is not as high as in S2, the section in the state where the possibility of a fire is most likely to occur and the section in the state A1-1 are determined as the sections in the state A. Further, in the third determination unit 306, when the section of the state A is adjacent to the section of the fire state SS and is in contact with the ceiling of the section of the fire state SS by a line or a point, a fire occurs as much as the fire possibility state S2. Although the possibility is not high, the section of the state A1-2 and the section of the state A, which are the second most likely to have a fire, are determined as the sections of the state A. Further, in the third judgment unit 306, when the section of the state A is adjacent to the section of the fire state SS and is on the same deck of the section of the fire state SS and is in contact with the wall with a line, the fire possibility state S2 is fired. Although it is not highly likely that a fire has occurred, the compartments of the state A1-3 and the compartments of the state A, which are the third most likely to have a fire, are determined as the compartments of the state A. Further, in the third determination unit 306, when the section of the state A is adjacent to the section of the fire state SS and is in contact with the floor of the section of the fire state SS on a surface, a fire has occurred as much as the fire possibility state S2. Although the possibility is not high, the section of the state A1-4 and the section of the state A, which are the fourth most likely to have a fire as the section of the state A, are determined. Further, in the third judgment unit 306, when the section of the state A is adjacent to the section of the fire state SS and is in contact with the floor of the section of the fire state SS by a line or a point, a fire occurs as much as the fire possibility state S2. Although it is not highly probable, the compartments of the state A1-5 and the compartments of the state A, which are the fifth most likely to have a fire, are determined as the compartments of the state A.
Further, in the third judgment unit 306, when the section in the state A does not touch the section in the fire state SS, the possibility that a fire has occurred is not as low as in the normal state, but a fire has occurred in the state A1-5. A section A2 (see FIG. 6) in a state in which the possibility of fire is low and a section in a state of unknown fire are determined.

The order of the possibility that a fire has occurred in the above-mentioned section of state A is an example, and the third judgment unit 306 is based on the materials of the ceiling, wall, floor, deck, and other conditions. The order may be changed. Further, when the section of the state A is adjacent to the sections of a plurality of fire states, the third determination unit 306 raises the order as the ground contact area becomes wider or the length of the grounding line becomes longer. There may be.

The priority order specifying unit 307 specifies the priority of the section to perform a predetermined measure based on the possibility of disaster occurrence (step S6).
Specifically, for example, the priority specifying unit 307 is in the order of high probability of disaster occurrence (SS, S1, S) indicated by the respective determination results by the first determination unit 303, the second determination unit 305, and the third determination unit 306. Extinguish fires in S2, X1-1, X1-2, X1-3, X1-4, X1-5, A1-1, A1-2, A1-3, A1-4, A1-5, A2, B). Increase the priority of the parcel.

The presentation control unit 308 causes the presentation unit to present a section for performing a predetermined action with the priority specified by the priority specification unit 307 (step S7).
Specifically, for example, a presentation unit is provided in the composite sensor 10, and a presentation control unit 308 presents a priority to a plurality of presentation units together with a section that needs to extinguish a fire.
