Although it is possible, it is difficult to determine whether or not the smoke generation state is an abnormal state.

  On the other hand, with the above-described configuration, it is possible to determine the abnormality of the target space based on the smoke detection result at the normal time. Therefore, the target space is a space where smoke is generated at the normal time. Even in this case, it is possible to correctly determine whether or not the state in which smoke is generated is an abnormal state. Therefore, an abnormality in the target space can be detected more accurately.

<Configuration and basic operation>
[Management system]
FIG. 1 is a diagram showing a configuration of a management system according to an embodiment of the present invention.

  With reference to FIG. 1, the management system 201 includes a management device 101 and a plurality of sensors 151.

  The sensor 151 is provided in the target space. The sensor 151 detects smoke regularly or irregularly, such as every 30 seconds. Then, the sensor 151 transmits the detection result to the management apparatus 101 by wireless communication, for example.

  The target space is, for example, in a factory provided with facilities such as a combustion furnace, and is in a state where smoke is generated in a normal time. In addition, the target space is composed of, for example, one closed space that is not physically partitioned.

  The management apparatus 101 includes a reception unit (acquisition unit) 11, a storage unit 12, a determination unit 13, and a notification unit 14.

  The receiving unit 11 receives detection results transmitted from the plurality of sensors 151 and stores the received detection results in the storage unit 12. In addition, the reception unit 11 outputs the received detection result to the determination unit 13.

  When receiving the detection result of each sensor 151 from the reception unit 11, the determination unit 13 comprehensively determines the detection result of each sensor 151 to determine whether an abnormality has occurred in the target space. For example, the determination unit 13 reads a plurality of past detection results stored in the storage unit 12. Then, the determination unit 13 comprehensively determines the plurality of read past detection results and the detection results of the sensors 151 received from the reception unit 11 to determine whether an abnormality has occurred in the target space. to decide.

  Specifically, as described above, smoke is generated in the normal time in the target space, and therefore the detection result of the plurality of sensors 151 in the state where the plurality of sensors 151 respectively detect smoke in the storage unit 12. Is saved. The detection result indicates, for example, smoke concentration.

  Then, the determination unit 13 determines a smoke concentration threshold Th as reference information based on a plurality of detection results read from the storage unit 12. The reference information is not limited to the threshold Th as long as it is information based on detection results of the plurality of sensors 151 in a state where the plurality of sensors 151 detect smoke.

  Then, for example, the determination unit 13 compares the smoke concentration indicated by each of the plurality of detection results received from the reception unit 11 with a threshold Th. For example, when the ratio of the detection results indicating the smoke concentration equal to or higher than the threshold Th among the plurality of detection results received from the reception unit 11 is equal to or greater than a predetermined value, the determination unit 13 has an abnormality in the target space. Judge that Then, the determination unit 13 outputs the determination result to the notification unit 14.

  When the determination result received from the determination unit 13 indicates that an abnormality has occurred in the target space, the notification unit 14 notifies the administrator or the like of the occurrence of the abnormality, such as sounding an alarm.

  The determination unit 13 may determine a threshold value Th having a different value for each sensor 151 or may determine a threshold value Th having the same value for the plurality of sensors 151.

  The determination unit 13 is not limited to the method of comparing the smoke concentration indicated by the detection result and the threshold Th, and based on the detection result of each sensor 151, determines an abnormality in the target space using another method. Also good. For example, the determination unit 13 uses the plurality of past detection results stored in the storage unit 12 as reference information, and compares the plurality of detection results received from the reception unit 11 with the reference information, thereby detecting an abnormality in the target space. May be judged.

  Further, the sensor 151 is not limited to smoke, and may be temperature or humidity as a detection target. In the target space, a sensor 151 for detecting smoke and a sensor 151 for detecting other than smoke may be provided in a mixed manner. Further, the target space may be a closed space or an open space.

  In addition, the target space may be a space that is partly or entirely physically partitioned by a structure such as a wall.

[Example of sensor placement]
The target space is virtually divided into a plurality of sections, and the plurality of sensors 151 are arranged so that at least one sensor 151 is included in each of the plurality of sections. Each section includes, for example, at least one different facility or is separated by a passage. Hereinafter, an example of the arrangement of the plurality of sensors 151 will be described.

(Example 1)
FIG. 2 is a diagram illustrating an example 1 of sensor arrangement in the management system according to the embodiment of the present invention.

  With reference to FIG. 2, equipment A1 and equipment A2 are provided in the target space X1. In this case, the target space X1 is partitioned so that, for example, the facility A1 and the facility A2 are included in different sections.

  Specifically, the target space X1 is divided into a section Ea1 including the facility A1 and a section Ea2 including the facility A2. The section Ea1 and the section Ea2 have substantially the same area and are aligned with each other.

  For example, one sensor 151 is disposed in each of the sections Ea1 and Ea2.

(Example 2)
FIG. 3 is a diagram illustrating a second example of sensor arrangement in the management system according to the embodiment of the present invention.

  Referring to FIG. 3, facilities B1 to B4 are provided in the target space X2. In this case, the target space X2 is partitioned so that, for example, the facilities B1 to B4 are included in different sections.

  Specifically, the target space X2 is partitioned into sections Eb1 to Eb6, for example, in a lattice shape. These sections Eb1 to Eb6 have substantially the same area and are aligned. The sections Eb1 to Eb4 include facilities B1 to B4, respectively, and the sections Eb5 and Eb6 do not include facilities.

  For example, one sensor 151 is arranged in each of the sections Eb1 to Eb6.

(Example 3)
FIG. 4 is a diagram showing a third example of sensor arrangement in the management system according to the embodiment of the present invention.

  Referring to FIG. 4, facilities C1 to C8 are provided in the target space X3. In addition, a passage P1 and a passage P2 are provided in the target space X3.

  In this case, for example, the target space X3 is a section in which adjacent areas are different via the passage P1, the areas adjacent to each other through the path P2 are different, and the facilities C1 to C8 are included in different sections. Is delimited.

  Specifically, the target space X3 is divided into sections Ec1 to Ec12, for example, in a lattice shape. These sections Ec1 to Ec12 have substantially the same area and are aligned. The sections Ec1 to Ec8 include facilities C1 to C8, respectively, and the sections Ec9 to Ec12 do not include facilities.

  For example, one sensor 151 is arranged in each of the sections Ec1 to Ec12.

  Note that the arrangement of the sensors 151 is not limited to the arrangement shown in the above-described examples 1 to 3. For example, a plurality of sensors 151 may be arranged in one section. A plurality of facilities may be included in one section.

  The target space may be divided into a plurality of sections having different areas. Further, the plurality of sections may not be aligned.

  However, as in Examples 1 to 3 described above, the plurality of sections have substantially the same area, and the plurality of sections are aligned, and each section includes at least one sensor 151. By arranging the plurality of sensors 151 in the first, the plurality of sensors 151 are arranged without bias in the entire target space. In this way, by arranging the plurality of sensors 151 without any bias in the entire target space, it is possible to grasp the entire target space and more accurately detect an abnormality in the target space.

  In other words, when a plurality of sections are aligned, it is preferable that the plurality of sections are aligned because the deviation of the arrangement of the sensors 151 is reduced. In addition, when the areas of the plurality of sections are substantially the same, it is more preferable that the areas of the plurality of sections are substantially the same because the bias of the arrangement of the sensors 151 is further reduced.

<Operation flow>
Next, an operation flow by the management apparatus 101 according to the embodiment of the present invention will be described.

  Each device in the management system 201 includes a computer, and an arithmetic processing unit such as a CPU in the computer reads and executes a program including a part or all of each step in the following flowchart from a memory (not shown). Each of the programs of the plurality of apparatuses can be installed from the outside. The programs of the plurality of apparatuses are distributed while being stored in a recording medium.

  FIG. 5 is a flowchart defining the flow of operation by the management apparatus according to the embodiment of the present invention.

  With reference to FIG. 5, first, the management apparatus 101 receives detection results from the plurality of sensors 151 arranged in the target space (step S11).

  Next, for example, the management apparatus 101 acquires reference information based on the past detection results of the plurality of sensors 151, and based on the acquired reference information and the detection results of each sensor 151 received in step S11, It is determined whether or not an abnormality has occurred in the space (step S12).

  When the management apparatus 101 determines that an abnormality has occurred in the target space (“YES” in step S13), the management apparatus 101 notifies the administrator or the like (step S14). And the management apparatus 101 performs the operation | movement shown to step S11-step S14 again.

  On the other hand, if the management apparatus 101 determines that no abnormality has occurred in the target space (“NO” in step S13), the management apparatus 101 performs the operations shown in steps S11 to S14 again without performing notification to the administrator or the like.

<Modification 1>
In the embodiment of the present invention described above, the determination unit 13 in the management apparatus 101 determines an abnormality in the target space based on the detection results of the plurality of sensors 151 and the reference information. However, the configuration is not limited to such a configuration, and the determination unit 13 may determine an abnormality in the target space based on the detection results of the plurality of sensors 151 arranged in each section without using the reference information. .

  Further, even when the sensor 151 is a sensor that detects smoke, the target space may be a space where smoke is not generated in a normal time.

<Modification 2>
The target space may not be divided into a plurality of sections. For example, the determination unit 13 in the management device 101 determines an abnormality in the target space based on the detection results of each of the plurality of sensors 151 provided in any place in the target space and the reference information as described above. May be.

  By the way, although the abnormality detection apparatus described in Patent Document 1 is configured to include a microphone for detecting an abnormal sound of a monitoring target such as a plant, it detects an abnormality in a factory or the like where the monitoring target is provided. May be difficult.

  On the other hand, in the management system 201 according to the embodiment of the present invention, the target space is divided into a plurality of sections, and each of the plurality of sections is arranged to include at least one sensor 151. The receiving unit 11 in the management apparatus 101 receives the detection results of the sensors 151 arranged as described above. Further, the determination unit 13 determines an abnormality in the target space based on each detection result received by the reception unit 11.

  When determining an abnormality of an individual facility, a detection result of a sensor attached to the facility or a sensor disposed in the vicinity of the facility is generally used. However, in such a method, it may be difficult to detect an abnormality in the space where the equipment is provided.

  Therefore, as described above, the configuration using the detection results of each of the plurality of sensors 151 arranged in a distributed manner in the target space makes it possible to grasp the overall status of the target space and more accurately detect the abnormality in the target space. Can be detected.

  In the management apparatus 101 according to the embodiment of the present invention, the target space is divided into a plurality of sections, and the plurality of sections are aligned.

  With such a configuration, since the bias of the arrangement of the sensors 151 is reduced, it is possible to more accurately grasp the entire state of the target space and more accurately detect the abnormality of the target space.

  In the management apparatus 101 according to the embodiment of the present invention, the target space is divided into a plurality of sections, and each section includes at least one different facility or is separated by a passage.

  For example, when there are a plurality of facilities in the target space, the situation may be greatly different between a peripheral area of one facility and a peripheral area of another facility. Further, the situation may be greatly different between areas adjacent to each other through a passage.

  Therefore, as described above, the plurality of sensors 151 can be arranged more effectively by dividing the target space so that the areas that may be greatly different from each other are divided into different sections.

  In the management system 201 according to the embodiment of the present invention, the sensor 151 can detect smoke.

  For example, if the target space is in a factory where smoke is normally generated and a sensor capable of detecting smoke is installed in or near the facility in the target space, the presence or absence of smoke is detected. Although it is possible, it is difficult to determine whether or not the smoke generation state is an abnormal state.

  On the other hand, as described above, the detection target of the sensor 151 is smoke, and by using the detection results of each of the plurality of sensors 151 arranged in the target space, the flow of smoke in the target space Alternatively, since it is possible to grasp the distribution, it is possible to correctly determine whether or not the state where the smoke is generated is an abnormal state by comparing with the flow or distribution of the smoke at the normal time.

  Further, in the management apparatus 101 according to the embodiment of the present invention, the target space is configured by one closed space that is not physically partitioned.

  In this way, when a plurality of sensors are distributed and arranged in one closed space that is not physically partitioned, the detection results of each sensor are likely to be related to each other, It is possible to prevent the detection sensor from being affected by erroneous detection and the like, and to detect an abnormality in the target space more accurately.

  In the management apparatus 101 according to the embodiment of the present invention, the determination unit 13 determines an abnormality in the target space based on the detection result of each sensor 151 and the reference information. The reference information is information based on the detection result of each sensor 151 in a state where each sensor 151 detects smoke.

  With such a configuration, the abnormality of the target space can be determined based on the smoke detection result at the normal time. Therefore, even if the target space is a space where smoke is generated at the normal time, the smoke It is possible to correctly determine whether or not the state in which the error occurs is an abnormal state. Therefore, an abnormality in the target space can be detected more accurately.

  Moreover, in the management apparatus 101 which concerns on embodiment of this invention, the receiving part 11 receives the detection result of the smoke by the some sensor 151 arrange | positioned in object space, respectively. The determination unit 13 determines an abnormality in the target space based on the detection results of the plurality of sensors 151 received by the reception unit 11 and the reference information. The reference information is information based on the detection results of the plurality of sensors 151 in a state where the plurality of sensors 151 detect smoke.

  For example, if the target space is in a factory where smoke is normally generated and a sensor capable of detecting smoke is installed in or near the facility in the target space, the presence or absence of smoke is detected. Although it is possible, it is difficult to determine whether or not the smoke generation state is an abnormal state.

  On the other hand, with the above-described configuration, the abnormality of the target space can be determined based on the smoke detection result at the normal time. Even in this case, it is possible to correctly determine whether or not the state in which smoke is generated is an abnormal state. Therefore, an abnormality in the target space can be detected more accurately.

  Note that some or all of the functions of the management apparatus 101 according to the embodiment of the present invention may be provided by cloud computing. That is, the management apparatus 101 according to the embodiment of the present invention may be configured by a plurality of cloud servers and the like.
