Embodiment
Hereinafter, embodiments will be described in detail with reference to the drawings.
The configuration of the disaster partition identification system 1 according to an embodiment of the present invention will be described.

  A disaster section identification system 1 according to an embodiment of the present invention is a system provided on a ship and estimating a section in which a disaster such as a fire may have occurred in the ship. As shown in FIG. 1, the disaster section identification system 1 includes a compound sensor 10 (one of the sensors), a fire sensor 20 (one of the sensors), and a disaster section identification device 30.

  As shown in FIG. 2, the composite sensor 10 is provided for each section of a plurality of sections (each section indicated by A1 to A12, B1 to B12, and C1 to C12 in FIG. 2) divided in advance in the ship. Be The combined sensor is a combination of the function of sensing smoke, the function of sensing temperature, the function of sensing water immersion, the function of emitting light, and the function of a speaker in a single container. The composite sensor 10 senses temperature, smoke, water immersion and the like. The function to detect the inundation, that is, the inundation sensor is for detecting whether there is inundation or the like in the ship. Further, the function of emitting light and the function of the speaker are for notifying the occupant of predetermined information.

The fire sensor 20 is a device that reports, based on the detection result of smoke, temperature, etc., whether the "fire" occurrence, the "normal" state, or the "fault" state is present. For example, when a fire occurs, the fire sensor 20 outputs a fire signal indicating that a fire has occurred. Also, for example, in the “normal” state, the fire sensor 20 outputs a normal signal indicating that it is normal. Also, for example, the fire detector 20 outputs a signal different from the fire signal and the normal signal (hereinafter referred to as “failure signal”) in the failure state. When the fire detector 20 is in a failure state, it is unknown whether a fire has occurred in the section where the fire detector 20 is provided. In the disaster area identification system 1 according to an embodiment of the present invention, the fire sensor 20 is housed in a separate housing from the compound sensor 10.
In the disaster area identification system 1 according to another embodiment of the present invention, the fire sensor 20 may be integrated into the composite sensor 10.

  The disaster section identification device 30 is an apparatus for estimating a section in which a disaster such as a fire may have occurred in the ship when a disaster such as a fire occurs in the ship. As illustrated in FIG. 3, the disaster section identification device 30 includes a storage unit 301, a data collection unit 302, a first determination unit 303, a disaster occurrence determination unit 304, a second determination unit 305, and a third determination unit. And a priority control unit 307 and a presentation control unit 308.

  The storage unit 301 stores section sensor information in which identification information of a plurality of sections in a ship is associated with identification information of the composite sensor 10 provided in each section. The storage unit 301 also stores section sensor information in which identification information of a plurality of sections in a ship is associated with identification information of the fire detectors 20 provided in each section. Further, the storage unit 301 stores section arrangement information in which identification information of a plurality of sections in a ship is associated with information on the arrangement and position of each section.

  The data collection unit 302 collects at least one of detection results of the fire detectors 20 provided in a plurality of sections of the ship and data acquired by the multiple sensors 10. The detection result of the fire sensor 20 is information indicating whether a fire has occurred, is in a normal state, or is in a failure state. The data acquired by the composite sensor 10 is data indicating the presence or absence of smoke detection, the temperature, and the like.

  The first determination unit 303 determines that there is a disaster in a plurality of sections based on the data collected by the data collection unit 302 (that is, at least one of the detection result of the fire sensor 20 and the data acquired by each composite sensor 10). Determine the possibility of disaster occurrence that indicates the possibility of occurrence. When the disaster is a fire, the first determination unit 303 determines that the fire state, the fire possibility state, the fire unknown state, or the normal state is classified as the possibility of the fire being generated. A fire condition is a condition where the possibility of a fire being generated is extremely high. Also, the fire possibility state is a state that is not as high as a fire state, but a high possibility of a fire being generated. Further, the fire unknown state is a state where fire information can not be obtained from the fire detector 20 or the composite sensor 10 due to a failure.

Specifically, for example, when the disaster is a fire, the first determination unit 303 receives a detection result (that is, a fire signal, a normal signal, or a failure signal) from the fire sensor 20.
If the detection result received from the fire detector 20 is a fire signal, the first determination unit 303 stores a division sensor that stores identification information that matches the identification information of the fire detector 20 that has output the fire signal. Identify in the information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 specified in the section sensor information is a fire state.
In addition, when the detection result received from the fire sensor 20 is a normal signal, the first determination unit 303 stores identification information that matches the identification information of the fire sensor 20 that has output the normal signal in the storage unit 301. Identify in the section sensor information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 specified in the section sensor information is in the normal state.
Further, when the detection result received from the fire detector 20 is a failure signal, the first determination unit 303 stores identification information that matches the identification information of the fire detector 20 that has output the failure signal in the storage unit 301. Identify in the section sensor information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 identified in the section sensor information is a fire unknown state where it is unclear whether a fire is occurring.

Also, specifically, for example, when the disaster is a fire, the first determination unit 303 receives the detection result of the temperature acquired by each of the composite sensors 10 from the data collection unit 302. The first determination unit 303 determines whether the temperature detection result is a temperature exceeding a predetermined threshold.
When the first determination unit 303 determines that the temperature detection result exceeds the predetermined threshold value, the storage unit 301 stores identification information that matches the identification information of the composite sensor 10 that has acquired those detection results. In the section 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 a fire state.
When the first determination unit 303 determines that the detection result of the temperature is lower than or equal to the predetermined threshold value, the increase rate of the temperature indicated by the detection result of the temperature is an increase rate exceeding the predetermined threshold value. Determine if there is.
When the first determination unit 303 determines that the detection result of the temperature has a rising rate exceeding a predetermined threshold value, identification information that matches the identification information of the composite sensor 10 from which the detection result is acquired is stored in the storage unit 301. It specifies in the division sensor information to memorize. 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.
In addition, when the first determination unit 303 determines that the detection result of the temperature is an increase rate equal to or less than a predetermined threshold value, the storage unit stores identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. It specifies in the division sensor information which 301 stores. 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 the normal state.
In addition, when the detection result of the temperature does not indicate the temperature (for example, when the detection result of the temperature indicates no signal), the first determination unit 303 matches the identification information of the composite sensor 10 that has acquired the detection result. The identification information to be identified is specified in the section 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 a fire unknown state.

Also, specifically, for example, when the disaster is a fire, the first determination unit 303 receives the detection result of the smoke acquired by each of the compound sensors 10 from the data collection unit 302. The first determination unit 303 determines whether or not the detection result of smoke has detected smoke from the detection results acquired by each of the compound sensors 10.
When the smoke detection result indicates that the smoke is detected, the first determination unit 303 stores the division sensor information in which the storage unit 301 stores identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. Identify 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 a fire state.
In addition, when the smoke detection result indicates that smoke is not detected, the first determination unit 303 stores, in the storage unit 301, identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. Identify in sensor information. 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 the normal state.
In addition, when the first determination unit 303 does not indicate whether the smoke detection result indicates the smoke detection (for example, when the smoke detection result indicates no signal), the composite sensor acquires the detection result. The identification information that matches the identification information of 10 is specified in the section 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 a fire unknown state.

  In addition, when there are a plurality of determination results, the first determination unit 303 determines, among the states indicated by the determination results, the state having the highest possibility of a fire being generated as the state of the section.

The disaster occurrence determination unit 304 determines, for each section, whether the possibility of occurrence of a disaster is high.
Specifically, for example, the disaster occurrence determination unit 304 determines whether each section is in a fire state.
Then, the disaster occurrence determination unit 304 identifies a section in a fire state as a section having a high possibility of occurrence of a disaster.

  The second determination unit 305 determines a section in the fire unknown state based on the connection relationship between the section that the disaster occurrence determination unit 304 has determined to be in the fire state and the section in the fire unknown state (the section where the sensor is broken). To determine the possibility of a disaster.

Specifically, for example, when the section in the fire unknown state 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, for example, the second judgment unit 305 fires about the fire possibility state Although it is not likely that there is a possibility that a fire has occurred, determine the compartment in the fire unknown state and the compartment in the fire unknown state that is most likely to be a fire. Here, the term “adjacent” as used herein includes not only those in contact with a surface but also those in contact with a line or a point. For example, the section B7 illustrated in FIG. 2 is adjacent to each of the sections A7, B3, B6, B8, B11, and C7 in plane. Further, the section B7 is adjacent to each of the sections A3, A6, A11, B2, B4, B10, B12, C3, C6, and C11 by a line. Further, the section B7 is adjacent to each of the sections A2, A10, C2 and C10 in point. In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and contacts the ceiling of the section in the fire state with a line or a point, a fire has occurred as much as a fire possibility state Although the possibility is not high, determine which compartment in the second highest possibility of a fire is occurring as a compartment in the unknown fire state and the compartment in the unknown fire state. In the second judgment unit 305, the section in the fire unknown state is adjacent to the section in the fire state and 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 If the fire is in the same floor as the compartment) or if it is connected to the wall by a line, the possibility of a fire being generated is not so high as possible, but a fire occurs as a division of unknown fire condition X Determine which compartments have the third highest probability of being and which compartments are in an unknown fire condition. In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and in contact with the floor of the section in the fire state, there is a possibility that a fire may occur as much as a fire possibility state Although it is not high, the division with the fourth highest possibility that a fire is occurring as a division of the fire unknown state X and the division of the fire unknown state are judged. In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state at a line or point, a fire has occurred as much as a fire possibility state Although the possibility is not high, determine the section with the fifth highest possibility of fire occurrence as a section in the fire unknown state and the section in the fire unknown state. In the second judgment unit 305, when the section in the fire unknown state does not contact the section in the fire state, the possibility that the fire is generated is not so low as the normal state, but the fire may be generated rather than the state Determine the low sex compartment and the fire unknown compartment.
Also, specifically, for example, when the section in the fire unknown state is in contact with a plurality of sections in the fire state in a plane, a line or a point, for example, the second judgment unit 305 can fire the section in the fire unknown state Determined as sex compartment.
The determination of the fire possibility section is based on the fact that when a fire occurs, the flame tends to move upward from the lower side, and the flame is more likely to spread as the ground contact area becomes wider.

Also, specifically, for example, when a section changes from the normal state to the fire unknown state, the second determination unit 305 supplies power from the power supply device to the composite sensor 10 or the fire sensor 20 of the section. A section in the unknown fire condition X through which the electric wire passes is determined as a section in the fire possibility state.
More specifically, for example, a section A in which the electric wire A feeding the composite sensor 10 or the fire sensor 20 from the power supply apparatus shown in FIG. 4 is provided, a section B in which the electric wire B is provided, etc. Information is stored in advance in the storage unit 301. As shown in FIG. 4, the electric wire B supplying power to the composite sensor 10 or the fire sensor 20 of the section B from the power feeding device passes through the section A, the section A is in the unknown fire state, and the section B is in the normal state It is assumed that When the section B changes from the normal state to the fire unknown state in such a state, the second determination unit 305 determines that the section through which the electric wire B passes is a section in the fire possibility state.
In this determination of fire possibility section, composite sensor 10 or fire sensor 20 of section B suddenly changes from normal state to fire unknown state because section A is in fire state and electric wire B is burned. It is based on the high possibility of being.

In addition, specifically, for example, the second determination unit 305 determines that the section in the fire unknown state is in the fire state through the ventilation duct of the same route (also regarded as the same when the path of the ventilation duct is branched) If connected to a compartment, determine the compartment in the unknown fire status as a compartment in the fire possibility status.
In addition, determination of this fire possibility division is based on the high possibility that a flame may spread through the ventilation duct of the same path | route.

  In addition, the order of the possibility that a fire has occurred as a section of the above-mentioned fire unknown state is an example, and the 2nd judgment part 305 is based on materials of ceiling, a wall, a floor, a deck, other conditions, etc. The order may be changed. In addition, when the section in the fire unknown state is adjacent to the sections in the fire state, the second determination unit 305 increases the rank as the ground contact area is wide or the length of the line to be grounded becomes long. It may be

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

  More specifically, for example, in the case where the section determined to have a low possibility of fire is adjacent to a section in a fire state and in contact with the ceiling or wall of the section in a fire state, for example, the third determination unit 306 Although the possibility of fire is not as high as possibility of fire occurrence, it is possible that a fire can occur with a section with the highest possibility of fire occurring as a section judged to have a low possibility of fire occurrence Determine the section judged to be low in gender. In addition, the third determination unit 306 determines that there is a possibility of fire if 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 at the line or point. A fire is not likely to have occurred, but a compartment in which it is determined that the fire possibility is low is the second highest possibility that the fire is likely to occur and the fire possibility is low. Determine the determined zone. Also, 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 on the same deck of the section in the fire state and is in contact with the wall by a line. The possibility of a fire occurring is not as high as the sexual condition, but it is the third highest possibility of a fire occurring as a section judged to have a low possibility of fire and the possibility of a fire occurring Is determined to be low. In the third judging unit 306, when the section judged to have a low possibility of fire is adjacent to the section in the fire state and in contact with the floor of the section in the fire state, the fire is more likely to occur. Although the possibility of occurrence is not high, it is judged that the possibility of fire occurrence is the fourth highest possibility and the possibility of fire occurrence is low. To determine which In addition, the third determination unit 306 determines that there is a possibility of fire if the section determined to have a low possibility of fire is adjacent to the section in a fire state and contacts the floor of the section in the fire state at a line or point. A fire is not likely to have occurred, but a compartment in which the possibility of a fire is determined to be low is determined to be the fifth highest possibility that a fire is occurring and a low possibility of a fire Determine the determined zone.

  Note that the rank of the possibility of a fire occurring as a section judged to have a low possibility of fire occurrence as described above is an example, and the third judgment unit 306 is a material of ceiling, wall, floor, deck, etc. The order may be changed based on the condition of 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 widens the ground area or increases the length of the line to be grounded. The order may be increased.

The priority specifying unit 307 specifies the priority of the partition to be subjected to the predetermined treatment based on the possibility of occurrence of a disaster.
Specifically, for example, the priority order identification unit 307 is a section that extinguishes in the descending order of the possibility of disaster occurrence indicated by each determination result by the first determination unit 303, the second determination unit 305, and the third determination unit 306. Increase the priority.

The presentation control unit 308 causes the presenting unit to present the section to be subjected to the predetermined treatment to the priority identified by the priority identifying unit 307.
Specifically, for example, a presentation unit is provided in the composite sensor 10, and the plurality of presentation units present the priorities together with the sections that need to be extinguished.

Next, processing of the disaster partition identification system 1 according to the embodiment of the present invention will be described.
Here, the processing flow of the disaster section identification device 30 according to the embodiment of the present invention shown in FIG. 5 will be described.
In the ship, a fire detector 20 and a composite sensor 10 having a function of a temperature sensor are provided in each section, and the processing of the disaster section identification device 30 will be described.

  The data collection unit 302 always collects data acquired by each of the compound sensors 10 provided in a plurality of sections of the ship (step S1). The data collection unit 302 outputs the collected data to the first determination unit 303.

The first determination unit 303 determines the possibility of occurrence of a disaster indicating the possibility that a disaster has occurred in each section based on the data collected by the data collection unit 302 (step S2).
Specifically, for example, the first determination unit 303 receives the detection result from the fire detector 20. If the detection result received from the fire detector 20 is a fire signal, the first determination unit 303 stores a division sensor that stores identification information that matches the identification information of the fire detector 20 that has output the fire signal. Identify in the information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 specified in the section sensor information is a fire state.
In addition, when the detection result received from the fire sensor 20 is a normal signal, the first determination unit 303 stores identification information that matches the identification information of the fire sensor 20 that has output the normal signal in the storage unit 301. Identify in the section sensor information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 specified in the section sensor information is in the normal state.
Further, when the detection result received from the fire detector 20 is a failure signal, the first determination unit 303 stores identification information that matches the identification information of the fire detector 20 that has output the failure signal in the storage unit 301. Identify in the section sensor information. The first determination unit 303 determines that the section associated with the identification information of the fire sensor 20 identified in the section sensor information is a fire unknown state where it is unclear whether a fire is occurring.

Further, specifically, for example, the first determination unit 303 receives the detection result of the temperature acquired by each of the compound sensors 10 from the data collection unit 302. The first determination unit 303 determines whether the temperature detection result is a temperature exceeding a predetermined threshold.
When the first determination unit 303 determines that the temperature detection result exceeds the predetermined threshold value, the storage unit 301 stores identification information that matches the identification information of the composite sensor 10 that has acquired those detection results. In the section 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 a fire state.
When the first determination unit 303 determines that the detection result of the temperature is lower than or equal to the predetermined threshold value, the increase rate of the temperature indicated by the detection result of the temperature is an increase rate exceeding the predetermined threshold value. Determine if there is.
When the first determination unit 303 determines that the detection result of the temperature has a rising rate exceeding a predetermined threshold value, identification information that matches the identification information of the composite sensor 10 from which the detection result is acquired is stored in the storage unit 301. It specifies in the division sensor information to memorize. 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.
In addition, when the first determination unit 303 determines that the detection result of the temperature is an increase rate equal to or less than a predetermined threshold value, the storage unit stores identification information that matches the identification information of the composite sensor 10 that has acquired the detection result. It specifies in the division sensor information which 301 stores. 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 the normal state.
In addition, when the detection result of the temperature does not indicate the temperature (for example, when the detection result of the temperature indicates no signal), the first determination unit 303 matches the identification information of the composite sensor 10 that has acquired the detection result. The identification information to be identified is specified in the section 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 a fire unknown state.

Then, since there are a plurality of determination results for each section, the first determination unit 303 indicates 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 sensor 20 If at least one of them is in a fire condition, it is determined that the section is in a state SS (see FIG. 6) which is highly likely to be a fire area.
In addition, since there are a plurality of determination results for each section, the first determination unit 303 indicates that the determination result based on the detection results of the fire sensor 20 indicates a fire unknown state, and the detection results of the composite sensor 10 are predetermined. If the rate of increase exceeds the threshold value, identification information that matches the identification information of the composite sensor 10 for which the detection result has been acquired is identified in the section sensor information stored in the storage unit 301. The first determination unit 303 determines the section associated with the identification information of the composite sensor 10 identified in the section sensor information to be a section of S1 (see FIG. 6) having a high possibility of the fire possibility state.
In addition, since there are a plurality of determination results for each section, the first determination unit 303 indicates that the determination result based on the detection results of the fire sensor 20 indicates a fire unknown state, and the detection results of the composite sensor 10 are predetermined. If the rate of increase is equal to or less than the threshold value, identification information that matches the identification information of the composite sensor 10 from which the detection result has been acquired is identified in the section 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 a section with low possibility A (see FIG. 6) in the fire possibility state.
Further, since there are a plurality of determination results for each section, the first determination unit 303 indicates a state indicated by the determination result based on the detection result of the composite sensor 10 and a state indicated by the determination result based on the detection result of the fire sensor 20. If both are in the fire unknown state, the section is judged as the section of the fire unknown state X (see FIG. 6). For example, the first determination unit 303 determines that the composite sensor 10 that has not acquired data is broken. In addition, for example, the first determination unit 303 determines that the fire sensor 20 is broken when the failure signal is obtained.
Further, since there are a plurality of determination results for each section, the first determination unit 303 indicates a state indicated by the determination result based on the detection result of the composite sensor 10 and a state indicated by the determination result based on the detection result of the fire sensor 20. If both are in a normal state, the section is determined to be a section in the state B (see FIG. 6) which is extremely unlikely to be a fire occurring section.

The disaster occurrence determination unit 304 determines, for each section, whether the possibility of occurrence of a disaster is high. 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 a section having a high possibility of occurrence of a disaster (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 determines the fire unknown state X based on the connection relationship between the division determined by the disaster occurrence determination unit 304 to be in the fire state SS and the division in the fire unknown state X (the division in which the sensor is broken). The possibility of disaster occurrence is determined for each of the sections (step S4).

Specifically, for example, when a section changes from a normal state to a fire unknown state, the second determination unit 305 causes the electric wire feeding the compound sensor 10 or the fire sensor 20 of the section from the power supply device. Determine the section of the passing fire unknown state X as the section of the fire possibility state.
More specifically, for example, a section A in which the electric wire A feeding the composite sensor 10 or the fire sensor 20 from the power supply apparatus shown in FIG. 4 is provided, a section B in which the electric wire B is provided, etc. Information is stored in advance in the storage unit 301. As shown in FIG. 4, the electric wire B supplying power to the composite sensor 10 or the fire sensor 20 of the section B from the power feeding device passes through the section A, the section A is in the unknown fire state, and the section B is in the normal state It is assumed that When the section B changes from the normal state to the fire unknown state in such a state, the second determination unit 305 determines that the section through which the electric wire B passes is a section in the fire possibility state S2.

  Also, specifically, for example, when the section in the fire unknown state X is in contact with a plurality of sections in the fire state in a plane, a line or a point, for example, the second judgment unit 305 determines the section in the fire unknown state X It is determined to be a section of the fire possibility state S2.

  Furthermore, specifically, for example, the second determination unit 305 determines that the section in the fire unknown state X is in the fire state via the ventilation duct of the same route (even when the path of the ventilation duct is branched). If it is connected to the section of the section, the section in the fire unknown 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 a section of the above-mentioned fire unknown state is an example, and the 2nd judgment part 305 is based on materials of ceiling, a wall, a floor, a deck, other conditions, etc. The order may be changed. In addition, when the section in the fire unknown state is adjacent to the sections in the fire state, the second determination unit 305 increases the rank as the ground contact area is wide or the length of the line to be grounded becomes long. It may be

  Also, specifically, for example, when the section in the fire unknown state X is in contact with a plurality of sections in the fire state in a plane, a line or a point, for example, the second judgment unit 305 may fire the section in the state A Determined as a section.

  Furthermore, specifically, for example, the second determination unit 305 determines that the section in the fire unknown state X is in the fire state via the ventilation duct of the same route (even when the path of the ventilation duct is branched). If it is connected to a compartment, the compartment of state A is judged as a fire possibility compartment.

In addition, the second determination unit 305 may fire on the fire unknown state X division based on whether the fire unknown state X division is in contact with the adjacent division in a plane, a line, or a point if the above conditions do not apply. Determine
Specifically, for example, 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 the wall of the section of the fire state SS, the second judgment unit 305 may possibly fire. The possibility of a fire being generated is not so high as in state A, but the division in fire unknown state X is the highest possibility that a fire is occurring. State X1-1 division (see FIG. 6) and fire unknown state Determine the compartments of In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and contacts the ceiling of the section in the fire state with a line or a point, a fire has occurred as much as a fire possibility state Although the possibility is not high, the section X1-2 (see FIG. 6) with the second highest possibility that a fire is occurring as a section in the fire unknown state is determined and the section in the fire unknown state. In the second judgment unit 305, the section in the fire unknown state is adjacent to the section in the fire state and 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 If the fire is in the same floor as the compartment) or if it is connected to the wall by a line, the possibility of a fire being generated is not so high as possible, but a fire occurs as a division of unknown fire condition X Determine the section with the third highest possibility of X1-3 (refer to FIG. 6) and the section in the fire unknown state. In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and in contact with the floor of the section in the fire state, there is a possibility that a fire may occur as much as a fire possibility state Although it is not high, the section X1-4 which is the fourth most likely to have a fire as a section of the unknown fire state X (see FIG. 6) and the section of the unknown fire state are determined. In the second judgment unit 305, when the section in the fire unknown state is adjacent to the section in the fire state and is in contact with the floor of the section in the fire state at a line or point, a fire has occurred as much as a fire possibility state Although the possibility is not high, the section X1-5 (see FIG. 6) and the section in the unknown fire state are determined as the fifth highest possibility that a fire is occurring as a section in the unknown fire state. In the second judgment unit 305, when the section in the fire unknown state does not contact the section in the fire state, the possibility that the fire is generated is not so low as the normal state, but the fire may be generated rather than the state Determine the low sex compartment and the fire unknown compartment.
In the second judgment unit 305, when the section in the fire unknown state does not contact the section in the fire state, the possibility that the fire is generated is not so low as the normal state, but the fire may be generated rather than the state Determine the compartment with low sex condition X2 (see Fig. 6) and the compartment with unknown fire condition.

  Next, the third determination unit 306 determines that the section of the state SS determined to have a high possibility of fire occurrence (that is, the section determined that the disaster occurrence determination unit 304 is in a fire state) and the possibility of a disaster occurrence is low. It was judged that the possibility of fire occurrence was low based on the connection relation between the judged state A compartments (that is, the compartments having the judgment result indicating the normal state and the judgment result indicating the unknown state X for the same block) The possibility of the occurrence of a disaster in the partition of the state A is determined (step S5).

More specifically, for example, the third determination unit 306 determines the possibility of fire when the section of state A is adjacent to the section of the fire state SS and 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 so high as in S2, a section in the state A where the possibility of a fire is the highest and a section in the state A1-1 are determined. If the section A is adjacent to the section in the fire state SS and is in contact with the ceiling of the section in the fire state SS with a line or point, the third determination unit 306 causes a fire to occur in the fire possibility state S2 However, the possibility of a fire being generated as a section of the state A is the second highest in the state A1-2 and the state A. In addition, the third determination unit 306 determines that the fire possibility state S2 is about fire when the section of state A is adjacent to the section of the fire state SS and on the same deck of the section of the fire state SS and is in contact with the wall by a line. Although the possibility of occurrence of is not high, the division of state A1-3 and the division of state A is determined as the third highest possibility that a fire is generated as a division of state A. In the third judgment unit 306, when the section of state A is adjacent to the section of the fire state SS and is in surface contact with the floor of the section of the fire state SS, a fire is generated as much as the fire possibility state S2 Although the possibility is not high, the section of state A1-4 and the section of state A which have the fourth highest possibility of fire being generated as the section of state A are determined. When the section A is adjacent to the section in the fire state SS and is in contact with the floor of the section in the fire state SS by a line or point, the third determination unit 306 causes a fire to occur in the fire possibility state S2 Although the possibility of the fire is not high, the division of the state A1-5 and the division of the state A, which is the fifth highest possibility that a fire has occurred as the division of the state A, is determined.
Further, when the section of state A does not contact the section of fire state SS, the third determination unit 306 is not likely to be more likely to have a fire than in the normal state, but a fire occurs than in state A1-5. To determine which section A2 (see FIG. 6) is less likely to be present and which is in an unknown fire condition.

  In addition, the order of the possibility that a fire has occurred as a section of the above-mentioned state A is an example, and the 3rd judgment part 306 is based on materials of ceiling, a wall, a floor, a deck, other conditions, etc. The order may be changed. Further, when the section of state A is adjacent to a plurality of sections in a fire state, the third determination section 306 makes the order higher as the ground area becomes wider or the length of the line to be grounded becomes longer. It may be.

The priority specifying unit 307 specifies the priority of the partition to be subjected to the predetermined treatment based on the possibility of occurrence of a disaster (step S6).
Specifically, for example, in the priority order identification unit 307, the first determination unit 303, the second determination unit 305, and the third determination unit 306 indicate the order of high possibility of occurrence of a disaster (SS, S1,. Extinguish fire on 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 partition priority.

The presentation control unit 308 causes the presenting unit to present the section to be subjected to the predetermined treatment to the priority order identified by the priority order identification unit 307 (step S7).
Specifically, for example, a presentation unit is provided in the composite sensor 10, and the presentation control unit 308 presents priorities to a plurality of presentation units together with sections that need to be extinguished.

In the disaster section identification system 1, the disaster section identification device 30 includes a first determination unit 303 and a second determination unit. The first determination unit 303 determines the possibility of occurrence of a disaster indicating the possibility of occurrence of a disaster in a plurality of sections based on the detection result of at least one of the composite sensor 10 and the fire sensor 20 (sensor). The second determination unit 305 determines whether the composite sensor 10 or the fire sensor 20 is based on the connection between the section determined to have a high possibility of occurrence of a disaster and the section where the composite sensor 10 or the fire sensor 20 is broken. Determine the possibility of disaster occurrence for the faulty section.
In this way, the disaster section identification device 30 according to an embodiment of the present invention can efficiently check the damage status of each section when a sensor that detects the occurrence of a disaster fails in a ship. .

In addition, the disaster area identification system 1 according to an embodiment of the present invention includes a third determination unit 306.

To determine the possibility of a disaster.
In this way, the disaster section identification device 30 according to one embodiment of the present invention efficiently checks the damage situation of each section more accurately when the sensor that detects the occurrence of a disaster fails in a ship. be able to.

  In another embodiment of the present invention, the composite sensor 10 may not have the function of the presentation unit, and in addition to the composite sensor 10 having the sensor function, the presentation unit may be provided in each section. .

  In the first determination unit 303 according to another embodiment of the present invention, there are three or more determination results, and among the states indicated by those determination results, the state having the highest possibility of fire occurrence is the section Of the composite sensor 10 and the fire sensor 20 except one of the composite sensor 10 and the fire sensor 20 which show the highest possibility of the occurrence of the fire. The state of the determined section may be further divided based on the state indicated by the determination result.

Specifically, the first determination unit 303 divides the state of each section into the state of the section with the highest possibility that a fire is occurring among the plurality of determination results, and the remaining determination results indicate Further divide the state of the compartment based on the possibility of a fire occurring. For example, when there are three determination results, the first determination unit 303 determines that the fire is most likely to occur among the three determination results (fire condition, fire condition, fire condition) ), (Fire status, fire status, fire possibility status), (fire status, fire status, fire unknown status), (fire status, fire status, normal status), (fire status, fire possibility status, fire possibility) State), (Fire state, Fire possibility state, Fire unknown state), (Fire state, Fire possibility state, Normal state), (Fire state, Fire unknown state, Fire unknown state), (Fire state, Fire unknown state) , Normal condition), and (fire condition, normal condition, normal condition) are determined as fire compartments. Then, the first determination unit 303 determines the remaining determination results of each section (fire status, fire status), (fire status, possibility of fire), (fire status, fire unknown status), (fire status, normal status) , (Fire possibility state, fire possibility state), (fire possibility state, fire unknown state), (fire possibility state, normal state), (fire unknown state, fire unknown state), (fire unknown state, normal State (a), (the normal state, normal state) The highest state that the fire is likely to occur is the fire state ((fire state, fire state), (fire state, possibility of fire), (fire) State, fire unknown state), (fire state, normal state) (group 1), the highest possibility of fire occurrence being fire possibility state ((fire possibility state, fire possibility) Condition), (fire possibility condition, fire unknown condition), (fire possibility) State, normal state) "(the second group), the state with the highest possibility of fire occurrence is fire unknown state" (fire unknown state, fire unknown state), (fire unknown state, normal state) " (A group including a fire unknown state) and “(normal state, normal state)” (third group) may be divided.
Also, similarly, the first determination unit 303 determines that three determination results are (fire possibility state, fire possibility state, fire possibility state), (fire possibility state, fire possibility state, fire unknown state), (Fire potential status, fire potential status, normal status), (fire potential status, fire unknown status, fire unknown status), (fire potential status, fire unknown status, normal status), (fire potential status, In the case of any of the normal state and the normal state), the section is determined as the section in the fire possibility state. Then, the first determination unit 303 determines the remaining determination results (fire possibility state, fire possibility state), (fire possibility state, fire unknown state), (fire possibility state, normal state), (fire unknown state) "(Fire possibility state, fire possibility state), (Fire possibility state), section of fire possibility state based on (fire unknown state), (fire unknown state, normal state), (normal state, normal state) Sex condition, fire unknown state), (fire possibility state, normal state) (group including fire possibility state), “(fire unknown state, fire unknown state), (fire unknown state, normal state)” (No. It may be divided into four groups) and "(normal state, normal state)" (fifth group).
Also, similarly, the first determination unit 303 has three determination results (fire unknown state, fire unknown state, fire unknown state), (fire unknown state, fire unknown state, normal state), (fire unknown state, normal) If the status is normal or normal, the section is determined to be a section in the fire unknown status. Then, the first determination unit 303 determines the section in the fire unknown state based on the remaining judgment results (fire unknown state, fire unknown state), (fire unknown state, normal state), (normal state, normal state), It may be divided into “(fire unknown state, fire unknown state), (fire unknown state, normal state)” (sixth group) and “(normal state, normal state)” (seventh group).

Furthermore, specifically, for example, when there are three determination results and the first determination unit 303 determines that the section is a section in a fire state, the remaining determination results (fire state, fire state), (fire State, possibility of fire), (fire state, fire unknown state), (fire state, normal state), (fire possibility state, fire possibility state), (fire possibility state, fire unknown state), (fire The state may be divided into possibility state, normal state), (fire unknown state, fire unknown state), (fire unknown state, normal state), and (normal state, normal state).
Also, specifically, for example, when there are three determination results and the first determination unit 303 determines that the section is a section in the fire possibility state, the remaining determination results (fire possibility state, fire possibility Sexual condition), (fire possibility status, fire unknown status), (fire possibility status, normal status), (fire unknown status, fire unknown status), (fire unknown status, normal status), (normal status, normal status) You may divide into each of).
Furthermore, specifically, for example, when there are three determination results and the section is determined to be a section in the fire unknown state, for example, the first determination unit 303 excludes one of the determination results indicating the fire unknown state. It may be divided into (fire unknown state, fire unknown state), (fire unknown state, normal state), and (normal state, normal state).
