(First embodiment)
FIG. 1 is a block diagram illustrating a schematic configuration of the abnormality sign detection system according to the first embodiment. As shown in FIG. 1, the abnormality sign detection system 1 according to the present embodiment includes an inspection terminal device 10 and a monitoring terminal device 20. The abnormality sign detection system 1 according to the present embodiment is a system for detecting an abnormality sign of a water and sewage plant, but the use of the abnormality sign detection system 1 is not limited to a water and sewage plant, but other types of plants. There may be.

  First, the inspection terminal device 10 will be described. The inspection terminal device 10 includes a behavior information recording unit 11, an abnormality sign detection unit 12, a voice transmission unit 13, and an abnormality sign database 14. The inspection terminal device 10 is a mobile terminal device that can be carried by an operator A who is an inspector. An example of this mobile terminal device is a tablet-type terminal device.

  The behavior information recording unit 11 includes an audio acquisition unit 111, a position detection unit 112, a time specifying unit 113, and a memory 114. The voice acquisition unit 111 acquires voice information indicating the voice of the operator A emitted from the plant. This audio information is an example of behavior information indicating the behavior of the operator A based on at least one of the five senses of the operator A.

  The position detection unit 112 detects the current position of the inspection terminal device 10, that is, the inspection location of the operator A carrying the inspection terminal device 10. The position detection unit 112 detects the inspection location of the operator A using, for example, a GPS (Global Positioning System) function. However, the method by which the position detection unit 112 detects the inspection location of the operator A is not particularly limited.

  The time specifying unit 113 has a clock function, and specifies the current time based on the clock function. The memory 114 records the audio information acquired by the audio acquisition unit 111. The sound information recorded in the memory 114 is added with the inspection place detected by the position detecting unit 112 and the current time specified by the time specifying unit 113 as a recording time.

  The abnormality sign detector 12 detects a plant abnormality sign based on the audio information recorded in the memory 114. The voice transmission unit 13 transmits the voice information detected by the abnormality sign detection unit 12 to the monitoring terminal device 20. The abnormality sign database 14 stores a keyword that is assumed to be issued by the operator A when an abnormality is suspected in the plant. This keyword is an example of abnormal sign behavior information related to the behavior of the operator A when an abnormality is suspected in the plant. The number of keywords is not particularly limited.

  Next, the monitoring terminal device 20 will be described. The monitoring terminal device 20 includes an audio reception unit 21 and an audio reproduction unit 22. In this embodiment, the monitoring terminal device 20 is a desktop personal computer, but may be a mobile terminal device such as a tablet terminal device.

  The voice receiving unit 21 receives the voice information transmitted from the inspection terminal device 10. The audio reproduction unit 22 reproduces the audio information received by the audio reception unit 21.

  Hereinafter, an example of the operation of the abnormality sign detection system 1 according to the present embodiment will be described with reference to FIG. 1 again. Here, it is assumed that the operator A makes a voice saying “Oh? Something strange? .

  First, the behavior information recording unit 11 records sound information indicating the sound emitted from the operator A (see step S1 in FIG. 1). Specifically, the voice acquisition unit 111 acquires this voice information and stores the acquired voice information in the memory 114. At this time, an inspection place is added to the audio information by the position detection unit 112 and a recording time is added by the time specifying unit 113. This is the recording step in this embodiment.

  Next, the abnormality sign detection unit 12 collates the voice information recorded in the behavior information recording unit 11 with the keyword stored in the abnormality sign database 14 (see steps S2 and S3 in FIG. 1). As a result, when the voice information matches the keyword, the abnormality sign detection unit 12 instructs the behavior information recording unit 11 to output the voice information to the voice transmission unit 13 (step S4 in FIG. 1). reference). This is the abnormality sign detection step in this embodiment. In this step S4, when a plurality of keywords are stored in the abnormality sign database 14, the abnormality sign detection unit 12 detects the sound information when at least one keyword matches the sound indicated by the sound information. May be issued. In addition, when the number of keywords matching the voice indicated in the voice information is equal to or greater than a predetermined number, the abnormality sign detection unit 12 may issue an instruction to transmit the voice information.

  When the behavior information recording unit 11 outputs audio information to the audio transmission unit 13 based on an instruction from the abnormality sign detection unit 12 (see step S5 in FIG. 1), the audio transmission unit 13 transmits the audio information to the monitoring terminal device 20. (See step S6 in FIG. 1). This is the transmission step in this embodiment.

  Thereafter, in the monitoring terminal device 20, the audio receiving unit 21 receives the audio information transmitted from the audio transmitting unit 13, and outputs the received audio information to the audio reproducing unit 22 (see step S7 in FIG. 1). This is the reception step in this embodiment.

  Finally, the audio reproduction unit 22 reproduces the audio information received from the audio reception unit 21 toward the operator B who is the person in charge (see step S8 in FIG. 1). This is the reproduction step in this embodiment. In the reproduction step, the audio reproducing unit 22 outputs a warning sound to the operator B before reproducing the audio information, and after the operator B performs an operation to instruct the monitoring terminal device 20 to reproduce the audio information. Audio information may be reproduced.

  In the abnormality sign detection system 1 according to this embodiment described above, the inspection terminal device 10 carried by the operator A who is an inspector determines whether or not there is a sign of abnormality in the plant based on the voice information of the operator A, If it is determined that there is a sign of abnormality, the audio information is transmitted to the monitoring terminal device 20. The monitoring terminal device 20 reproduces the voice information transmitted from the inspection terminal device 10 toward the operator B who is the person in charge.

  For this reason, when the inspector detects an abnormality sign of the plant during the inspection work, voice information indicating the detection of the abnormality sign is automatically notified to the person in charge without waiting for the completion of the inspection work. Thereby, the person in charge can grasp | ascertain the abnormal sign of a plant rapidly.

  Moreover, since the inspection terminal device 10 is a mobile terminal, the person in charge can detect a sign of an abnormality in the plant regardless of where the inspector is in the plant. Further, when the monitoring terminal device 20 is also a mobile terminal, a sign of plant abnormality can be grasped regardless of where the responsible person is.

  Furthermore, since the monitoring terminal device 20 reproduces the voice of the inspector itself, the person in charge who understands the characteristics of the inspector can guess the degree of the symptom of abnormality and the urgency thereof by listening to the voice. The accuracy of abnormal signs can be increased.

(Second Embodiment)
An abnormality sign detection system according to the second embodiment will be described. FIG. 2 is a block diagram illustrating a schematic configuration of the abnormality sign detection system according to the second embodiment. As shown in FIG. 2, the abnormality sign detection system 1a according to the present embodiment includes an inspection terminal device 10a and a monitoring terminal device 20a.

  First, the inspection terminal device 10a will be described. The inspection terminal device 10a includes a behavior information recording unit 11a, an abnormality sign detection unit 12a, an image transmission unit 13a, and an abnormality sign database 14a. The inspection terminal device 10a is a mobile terminal device that can be carried by the operator A, similarly to the inspection terminal device 10 according to the first embodiment.

  The behavior information recording unit 11a includes an image acquisition unit 111a, a position detection unit 112, a time specifying unit 113, and a memory 114. The behavior information recording unit 11a differs from the behavior information recording unit 11 according to the first embodiment in that an image acquisition unit 111a is provided instead of the sound acquisition unit 111.

  The image acquisition unit 111a acquires continuous image information acquired from the operator A in the plant. This image information is another example of the behavior information of the operator A. The configuration of each of the position detection unit 112 and the time specification unit 113 has been described in the first embodiment, and a description thereof will be omitted.

  The memory 114 records the image information acquired by the image acquisition unit 111a. The image information recorded in the memory 114 is added with the inspection place detected by the position detecting unit 112 and the current time specified by the time specifying unit 113 as a recording time.

  The abnormality sign detection unit 12 a detects a plant abnormality sign based on the image information recorded in the memory 114. The image transmission unit 13a transmits the image information detected by the abnormality sign detection unit 12a to the monitoring terminal device 20a.

  The abnormality sign database 14a stores operation pattern information indicating an operation pattern estimated to be performed by the operator A when an abnormality is suspected in the plant. This operation pattern information is another example of the abnormal sign behavior information.

  Next, the monitoring terminal device 20a will be described. The monitoring terminal device 20a includes an image receiving unit 21a and an image reproducing unit 22a. In the present embodiment, the monitoring terminal device 20a is a desktop personal computer, like the monitoring terminal device 20 according to the first embodiment, but may be a mobile terminal device such as a tablet terminal device.

  The image receiving unit 21a receives the image information transmitted from the inspection terminal device 10a. The image reproducing unit 22a reproduces the image information received by the image receiving unit 21a.

  Hereinafter, an example of the operation of the abnormality sign detection system 1a according to the present embodiment will be described with reference to FIG. 2 again. Here, it is assumed that the operator A is stationary in front of the water distribution pump P when he / she hears the abnormal sign S of the water distribution pump P during the inspection work with the water distribution pump P.

  First, the behavior information recording unit 11a records continuous image information acquired from the operator A (see step S1a in FIG. 2). Specifically, the image acquisition unit 111 a acquires image information, and stores the acquired image information in the memory 114. At this time, an inspection place is added to the image information by the position detection unit 112 and a recording time is added by the time specifying unit 113. This is the recording step in this embodiment.

  Next, the abnormality sign detection unit 12a analyzes the image information recorded in the behavior information recording unit 11a using the operation pattern information stored in the abnormality sign database 14a (see steps S2a and S3a in FIG. 2). In the present embodiment, the abnormality sign detection unit 12a identifies the rest time of the operator A from the image information, and compares the identified rest time with the rest time of the operation pattern information. As a result, when the stationary time of the image information is the same as or longer than the stationary time of the motion pattern information, the abnormality sign detecting unit 12a outputs the image information to the image transmitting unit 13a to the behavior information recording unit 11a. An instruction is given (see step S4a in FIG. 2). This is the abnormality sign detection step in this embodiment.

  When the behavior information recording unit 11a outputs image information to the image transmission unit 13a based on an instruction from the abnormality sign detection unit 12a (see step S5a in FIG. 2), the image transmission unit 13a transmits the image information to the monitoring terminal device 20a. (See step S6a in FIG. 2). This is the transmission step in this embodiment.

  Thereafter, in the monitoring terminal device 20a, the image receiving unit 21a receives the image information transmitted from the image transmitting unit 13a, and outputs the received image information to the image reproducing unit 22a (see step S7a in FIG. 2). This is the reception step in this embodiment.

  Finally, the image reproduction unit 22a reproduces the image information received from the image reception unit 21a toward the operator B (see step S8a in FIG. 2). This is the reproduction step in this embodiment. Note that, also in the reproduction step according to this embodiment, as in the first embodiment, the image reproduction unit 22a outputs a warning sound to the operator B before reproducing the image information. The image information may be reproduced after an operation for instructing the monitoring terminal device 20a to perform the reproduction.

  In the abnormality sign detection system 1a according to the present embodiment described above, as in the first embodiment, the inspection terminal apparatus 10a has a sign of abnormality in the plant based on the image information acquired from the operator A who is an inspector. If it is determined that there is a sign of abnormality, the image information is transmitted to the monitoring terminal device 20a. The monitoring terminal device 20a reproduces the image information transmitted from the inspection terminal device 10a toward the operator B who is the person in charge. Therefore, when the inspector detects an abnormality sign of the plant during the inspection work, image information indicating the detection of the abnormality sign is automatically notified to the person in charge without waiting for the completion of the inspection work. Thereby, the person in charge can grasp | ascertain the abnormal sign of a plant rapidly.

  In particular, in this embodiment, an abnormality sign is detected based on image information acquired from an inspector. Therefore, when a silent inspector performs a characteristic operation when an abnormal sign is detected, it is possible to quickly notify the responsible person as operation pattern information indicating the operation pattern as image information.

(Modification)
An abnormality sign detection system according to a modification of the second embodiment will be described. The configuration of the abnormality sign detection system according to this modification is the same as that of the abnormality sign detection system 1a according to the second embodiment shown in FIG. Hereinafter, an example of the operation of the abnormality sign detection system according to this modification will be described.

  First, the behavior information recording unit 11a records continuous image information acquired from the operator A, as in the second embodiment. However, in this modification, identification information for identifying an operator who is an inspector is added to the image information when the behavior information recording unit 11a records the image information. This is the recording step in this modification.

  Next, the abnormality sign detection unit 12a analyzes the image information recorded in the behavior information recording unit 11a using the operation pattern information stored in the abnormality sign database 14a. FIG. 3A is a diagram illustrating an example of operation pattern information stored in the abnormality sign database 14a according to the present modification.

  FIG. 3A shows operation pattern information for each operator. Specifically, the operation pattern information 141 of the operator A1, the operation pattern information 142 of the operator A2, and the operation pattern information 143 of the operator A3 are stored in the abnormality sign database 14a.

  The operation pattern information 141 indicates an operation pattern in which the operator A1 is stationary in front of the inspection place when an abnormality is suspected in the plant. The operation pattern information 142 indicates an operation pattern that the operator A2 goes back and forth in front of the inspection place when an abnormality is suspected in the plant. The operation pattern information 143 indicates an operation pattern in which the operator A3 rushes toward a specific direction from the inspection place when an abnormality is suspected in the plant.

  On the other hand, FIG. 3B is a diagram illustrating an example of image information recorded in the behavior information recording unit 11a. FIG. 3B shows image information 151 of the operator A1, image information 152 of the operator A2, and image information 153 of the operator A3.

  For example, when the image information 151 is recorded in the behavior information recording unit 11a, the abnormality sign detection unit 12a identifies the rest time x1 of the operator A1 by analyzing the image information 151. Subsequently, the abnormality sign detection unit 12a selects the operation pattern information 141 of the operator A1 from the operation pattern information 141 to 143 based on the identification information of the operator A1 added to the image information 151. Then, the abnormality sign detection unit 12a compares the stationary time x1 of the image information 151 with the stationary time xth of the motion pattern information 141. As a result, when the stationary time x1 of the image information is the same as or longer than the stationary time xth of the motion pattern information, the abnormality sign detection unit 12a outputs the image information 151 to the behavior information recording unit 11a to the image transmission unit 13a. To instruct.

  When the image information 152 is recorded in the behavior information recording unit 11a, the abnormality sign detection unit 12a analyzes the image information 152 to identify the movement locus of the operator A2 indicated in the image information 152. Subsequently, the abnormality sign detection unit 12a selects the operation pattern information 142 of the operator A2 from the operation pattern information 141 to 143 based on the identification information of the operator A2 added to the image information 152. Then, the abnormality sign detection unit 12a compares the movement locus indicated in the image information 152 with the movement locus indicated in the operation pattern information 142. Specifically, a standard movement range of + yth to −yth centering on the inspection place is set in advance, and the abnormality sign detection unit 12a operates based on the movement path and operation indicated in the image information 152 based on the standard movement range. The movement trajectory indicated in the pattern information 142 is compared. As a result, when the number of locations outside the standard movement range in the movement trajectory shown in the image information 152 is the same as or larger than the movement trajectory shown in the motion pattern information 142, the abnormality sign detection unit 12a records the behavior information. The unit 11a is instructed to output the image information 152 to the image transmission unit 13a.

  Further, when the image information 153 is recorded in the behavior information recording unit 11a, the abnormality sign detection unit 12a calculates the moving speed Δy1 / Δx1 of the operator A3 by analyzing the image information 153. Subsequently, the abnormality sign detection unit 12a selects the operation pattern information 143 of the operator A3 from the operation pattern information 141 to 143 based on the identification information of the operator A3 added to the image information 153. Then, the abnormality sign detection unit 12a compares the movement speed Δy1 / Δx1 of the operator A3 calculated from the image information 153 with the movement speed Δy / Δx indicated in the operation pattern information 143. As a result, when the movement speed Δy1 / Δx1 is equal to or greater than the movement speed Δy / Δx, the abnormality sign detection unit 12a instructs the behavior information recording unit 11a to output the image information 152 to the image transmission unit 13a. To do.

  The above is the abnormality sign detection step in the present modification. Since the operation content after the abnormality sign detection step is the same as that of the second embodiment, the description thereof is omitted.

  According to the above-described modification, operation pattern information is stored for each operator in the abnormality sign database 14a, and the abnormality sign detection unit 12a analyzes image information using the operation pattern information corresponding to each operator. . Therefore, since a plant abnormality sign can be detected according to the operation characteristics of each operator, the plant abnormality sign can be detected with high accuracy.

  In this modification, it is assumed that the operation content when an abnormality is suspected in the plant is different for each operator, but this operation content may be the same. For example, when the operators A1 to A3 are stationary when an abnormality is suspected in the plant, the abnormal sign of the plant is increased according to the characteristics of each operator's operation by setting the stationary time xth of the operation pattern information for each operator. It can be detected accurately.

  Further, the operation contents of the operators A1 to A3 when the plant is suspected of being abnormal are not limited to the above-described operation contents. For example, when the image acquisition unit 111a of the behavior information recording unit 11a is a camera having a zoom-up function, the abnormality sign detection unit 12a may detect a plant abnormality sign based on the zoom-up time.

  Specifically, the abnormality sign detection unit 12a identifies the zoom-up time from the image information recorded in the behavior information recording unit 11a, and zooms in the operation pattern information stored in the abnormality sign database 14a. Compare with uptime. As a result, when the zoom-up time of the image information is the same as or longer than the zoom-up time of the operation pattern information, the abnormality sign detection unit 12a outputs the image information 152 to the behavior information recording unit 11a to the image transmission unit 13a. To instruct.

  When detecting an abnormal sign of a plant based on the zoom-up time as described above, the zoom-up time of the operation pattern information stored in the abnormal sign database 14a is set for each operator, so that the characteristics of the operation of each operator Accordingly, it is possible to detect an abnormal sign of the plant with high accuracy.
