Description

[Technical field]

[0001] An embodiment of the present invention relates to an abnormality monitoring system, an abnormality monitoring method, and a program. [Background technology]

[0002] Conventionally, in the operation and management of plants such as water supply and sewage facilities, devices that output process data that continuously records the state of the plant are generally used. Operators in charge of inspecting the plant diagnose abnormalities in the plant by analyzing the numerical values ​​of the process data output from the devices.

[0003] In this type of plant operation management, an operator detects signs of abnormality in the plant based on his / her five senses while inspecting the plant on-site before the numerical values ​​of the process data become abnormal. In this case, the operator writes down the fact that he / she detected the signs of abnormality in the work log. Then, after the inspection work, the operator reports the contents of the work log to the person in charge, so that the person in charge can grasp the signs of abnormality.

[0004] However, if the operator's inspection work takes a long time, it is expected that the operator's report to the person in charge will be delayed. In this case, there is a concern that it will take a long time for the person in charge to grasp the signs of abnormality in the plant. For this reason, Patent Document 1 discloses an anomaly monitoring system and an anomaly monitoring method in which an anomaly discovered by the operator is shared between the operator and the person in charge. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2016-212560 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, such conventional abnormality monitoring systems and methods have the following problems.

[0007] For example, when it comes to inspection work for water supply and sewerage facilities, many pieces of equipment work together to perform their designated functions, and each piece of equipment is often located far away. As a result, (1) multiple operators often carry out inspections simultaneously in parallel, and (2) since a small number of operators inspect many pieces of equipment, the equipment that each operator is responsible for may change from day to day.

[0008] Due to the above (1), the burden on the person in charge increases, and there is a risk that a prompt response will not be possible when an abnormality occurs. For example, in order to promptly respond to an abnormality, the person in charge needs to be the starting point for contacting and coordinating with other operators, which increases the burden on the person in charge. In addition, even for equipment with low urgency, the person in charge is notified each time an abnormality is discovered, so the burden on the person in charge increases further. This may result in a delay in responding to abnormalities that should be addressed. In addition, since many operators are inspecting at the same time, it takes time to understand the status of each inspection task, and there is a risk that a prompt response will not be possible when an abnormality occurs.

[0009] In addition, due to the reason mentioned in (2) above, there is a risk that an abnormality may be overlooked due to differences in the operator's level of proficiency and experience. In other words, when an operator is inspecting equipment that he or she is unfamiliar with, there is a risk that the operator will not notice and overlook an abnormality that an experienced operator would have detected.

[0010] The problem that the present invention aims to solve is to provide an anomaly monitoring system, an anomaly monitoring method, and a program that enable abnormality information detected by one operator to be shared with another operator inspecting related equipment, thereby reducing the burden on the person in charge, while reliably discovering abnormalities and enabling necessary measures to be taken swiftly at an early stage, without relying on the operator's level of proficiency or skill. [Means for solving the problem]

[0011] The abnormality monitoring system according to the embodiment includes a plurality of inspection terminal devices and a monitoring terminal device capable of communicating with each of the plurality of inspection terminal devices. The plurality of inspection terminal devices include a position detection unit that detects the position of the inspection terminal device and outputs position information, an inspection terminal transmission / reception unit that transmits abnormality information of the equipment to be inspected together with the position information to the monitoring terminal device and receives the information transmitted from the monitoring terminal device, and an inspection terminal output unit that outputs the information received by the inspection terminal transmission / reception unit. The monitoring terminal device includes a monitoring terminal transmission / reception unit that receives the position information and abnormality information transmitted from the inspection terminal transmission / reception unit, a definition information database that stores definition information that defines equipment that will share the abnormality information among the plurality of equipment, and an abnormality information sharing equipment determination unit that determines equipment that will share the abnormality information received by the monitoring terminal transmission / reception unit based on the position information transmitted together with the abnormality information received by the monitoring terminal transmission / reception unit and the definition information stored in the definition information database. The monitoring terminal transmission / reception unit transmits the abnormality information to the inspection terminal device used to inspect the equipment determined by the abnormality information sharing equipment determination unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as the actual ones. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, the same reference numerals are used for elements similar to those described above with respect to the previous drawings, and detailed explanations and duplicated explanations are omitted as appropriate.

[0014] FIG. 1 is a simplified block diagram showing an example of the overall configuration of an abnormality monitoring system to which an abnormality monitoring method is applied, which is common to each of the embodiments described below.

[0015] As shown in FIG. 1, the abnormality monitoring system 1 includes a plurality of inspection terminal devices 10 that can be carried by each operator of a plant consisting of a plurality of facilities, such as a water supply and sewerage plant, and a monitoring terminal device 20 that can communicate with each of the plurality of inspection terminal devices 10 via a communication network, such as the Internet.

[0016] In each of the embodiments described below, the target to which the anomaly monitoring system 1 is applied is not necessarily limited to water supply and sewerage plants, but may be other plants, facilities, and the like.

[0017] (First embodiment) An abnormality monitoring system to which the abnormality monitoring method of the first embodiment is applied will be described.

[0018] According to the anomaly monitoring system of the present embodiment, abnormality information detected by an operator can be shared with another operator inspecting related equipment, thereby reducing the burden on the person in charge.

[0019] FIG. 2 is a block diagram showing an example of a schematic configuration of an inspection terminal device and a monitoring terminal device in the anomaly monitoring system according to the first embodiment.

[0020] First, the inspection terminal device 10 will be described. The inspection terminal device 10 is a mobile terminal device that can be carried by an operator who is an inspector. In FIG. 2, as examples of the inspection terminal device 10, only the inspection terminal device 10 operated by an operator A and the inspection terminal device 10 operated by an operator C are shown, but the number of inspection terminal devices 10 is not limited and is prepared according to the number of operators who are inspectors. As the mobile terminal device, although it is not limited, for example, a tablet-type terminal device can be applied.

[0021] The inspection terminal device 10 has a behavior information recording unit 11 , an abnormality monitoring unit 12 , an inspection terminal transmitting / receiving unit 13 , an abnormality sign database 14 , and an inspection terminal output unit 16 .

[0022] The behavior information recording unit 11 includes a voice acquisition unit 111 , a position detection unit 112 , a time identification unit 113 , and a memory 114 .

[0023] The voice acquisition unit 111 can be realized by, for example, a microphone, but is not limited thereto, and acquires voice information f indicating the voice of an operator uttered in the plant. This voice information f is an example of behavior information of the operator based on at least one of the five senses of the operator.

[0024] The position detection unit 112 detects the current position of the inspection terminal device 10 and outputs position information a. The current position of the inspection terminal device 10 is also the current position of the operator A. The position detection unit 112 can detect the current position of the inspection terminal device 10, for example, by using a GPS (Global Positioning System) function, but the current position may be detected by using a function other than GPS.

[0025] The time determination unit 113 has a clock function, and uses this clock function to output time information g indicating the current time.

[0026] The memory 114 records the voice information f acquired by the voice acquisition unit 111, the position information a detected by the position detection unit 112, and the time information g output by the time identification unit 113 in association with each other.

[0027] The abnormality sign database 14 stores keywords h that are expected to be uttered by the operator when an abnormality is suspected in the equipment inspected by the inspection terminal device 10. Therefore, the keywords h are an example of abnormality sign behavior information related to the behavior of the operator when an abnormality is suspected in the equipment. Note that the number of keywords h stored in the abnormality sign database 14 is not particularly limited.

[0028] The anomaly monitoring unit 12 compares the voice information f recorded in the memory 114 with the keyword h stored in the anomaly sign database 14. If the voice information f contains the keyword h, the anomaly monitoring unit 12 determines that the voice information f is a sign of an anomaly.

[0029] Furthermore, in the case where a plurality of keywords h are stored in the abnormality sign database 14, the abnormality monitoring unit 12 can also determine that the voice information f is a sign of an abnormality when at least one of the keywords h is included in the voice information f.

[0030] The abnormality monitoring unit 12 can also determine that a case in which the number of keywords h included in the voice information f is equal to or greater than a predetermined number is a sign of an abnormality.

[0031] When the abnormality monitoring unit 12 determines a sign of an abnormality in this manner, it generates abnormality information b including the voice information f and outputs it to the behavior information recording unit 11.

[0032] When abnormality information b is output from the abnormality monitoring unit 12, the behavior information recording unit 11 outputs the output abnormality information b together with the corresponding position information a and time information g to the inspection terminal transmitting / receiving unit 13. As described above, since the position information a and time information g are associated with the voice information f recorded in the memory 114, the corresponding position information a and time information g are the position information a and time information g associated with the voice information f contained in the abnormality information b.

[0033] The inspection terminal transmitting / receiving unit 13 transmits the abnormality information b, the position information a, and the time information g output from the behavior information recording unit 11 to the monitoring terminal device 20 via a communication network such as the Internet.

[0034] The monitoring terminal device 20 is operated by a responsible operator (e.g., operator B) and is preferably a desktop personal computer installed in a central control room, but is not limited to this and may be a mobile terminal device such as a tablet terminal device.

[0035] The monitoring terminal device 20 has a monitoring terminal output unit 21 , a monitoring terminal transmitting / receiving unit 22 , an anomaly information sharing facility determining unit 23 , and a definition information database 24 .

[0036] The monitoring terminal transceiver unit 22 receives the anomaly information b, location information a, and time information g transmitted from the inspection terminal transceiver unit 13 of the inspection terminal device 10 via a communication network such as the Internet, and outputs it to the anomaly information sharing equipment determination unit 23.

[0037] The definition information database 24 stores definition information d that defines pairs or groups of equipment that share anomaly information b among a plurality of equipment. Specifically, equipment that shares anomaly information b is equipment that may be affected when an abnormality occurs in a certain equipment.

[0038] For example, equipment in a water supply and sewerage plant is connected by pipelines for carrying liquids such as water and chemicals. Therefore, if there is an abnormality in a water pump installed in the pipeline, it may affect the water reservoir to which the water or chemicals are supplied by the water pump. Therefore, if there is an abnormality in a certain equipment, the equipment connected to that equipment by the pipeline may be affected by the abnormality.

[0039] For example, the equipment in a water supply and sewerage plant is electrically connected to it by communication lines for status monitoring and control. Therefore, if an abnormality occurs in one piece of equipment, the equipment electrically connected to that equipment by communication lines may also be affected by the abnormality.

[0040] Therefore, the definition information d includes connection relationship information that indicates the connection relationships of the pipelines and communication lines between the facilities.

[0041] In this specification, the terms "facility" and "equipment" are used synonymously. Therefore, the term "facility" may be understood as being interchangeable with "equipment."

[0042] The anomaly information sharing facility determining unit 23 determines a facility with which the anomaly information b is to be shared, based on the position information a received by the monitoring terminal transmitting / receiving unit 22 and the definition information d stored in the definition information database 24 .

[0043] For example, the anomaly information sharing equipment determination unit 23 identifies an equipment where an anomaly has occurred from the location information a, and determines, from the definition information d, an equipment that has a connection relationship with the identified equipment via a pipeline or a communication line as an equipment that will share the anomaly information b. Then, the unit outputs equipment information (e.g., an identification number) e indicating the determined equipment to the monitoring terminal transmitting / receiving unit 22.

[0044] Based on the equipment information e output from the anomaly information sharing equipment determination unit 23, the monitoring terminal transceiver unit 22 transmits the anomaly information b, location information a, and time information g to the inspection terminal device 10 of the operator (e.g., operator C) in charge of inspecting the equipment indicated in the equipment information e, via a communication network such as the Internet.

[0045] In response to this, in the inspection terminal device 10 of operator C, the inspection terminal transceiver unit 13 receives the abnormality information b, position information a, and time information g transmitted from the monitoring terminal device 20, and outputs them to the inspection terminal output unit 16.

[0046] In order for the monitoring terminal transmitting / receiving unit 22 to transmit the abnormality information b, the position information a, and the time information g to the inspection terminal device 10 of the operator in charge of inspecting the equipment indicated by the equipment information e, the monitoring terminal device 20 needs to know the position of each inspection terminal device 10. Since the position of each inspection terminal device 10 can be known by various methods, there is no particular limitation in this specification, but for example, it can be realized by each inspection terminal device 10 constantly or periodically transmitting the position information a detected by the position detection unit 112 to the monitoring terminal device 20 together with the identification number of the inspection terminal device 10.

[0047] The inspection terminal output unit 16 outputs the anomaly information b, location information a, and time information g output from the inspection terminal transmitting / receiving unit 13. The inspection terminal output unit 16 can be realized, for example, by a display or a speaker, and can display the location information a and time information g as characters or images on the display, and can output audio information f included in the anomaly information b from the speaker.

[0048] In this way, the abnormality information b from operator A's inspection terminal device 10 is transmitted to the monitoring terminal device 20 operated by operator B, who is the person in charge, and is further transmitted from the monitoring terminal device 20 to the inspection terminal device 10 of operator C, who is inspecting equipment that may be affected by the abnormality.

[0049] As a result, abnormality information b detected by operator A is shared not only with operator B, who is the person in charge, but also with operator C.

[0050] Next, the sharing of abnormality information in the abnormality monitoring system of this embodiment will be described by taking as a specific example a case in which the abnormality monitoring system of this embodiment is applied to a water supply and sewerage plant.

[0051] First, a first specific example will be described with reference to FIG.

[0052] FIG. 3 is a hierarchical structure diagram showing an example of the connection relationship of pipelines between the various facilities of a water supply and sewerage plant.

[0053] The hierarchical structure of the water supply and sewerage plant 300 illustrated in FIG. 3 is made up of a first level, a second level, and a third level, in that order from the upper level to the lower level.

[0054] The first tier corresponds to the water purification plant, and in this example there is a first water purification plant and a second water purification plant.

[0055] The second tier corresponds to the water distribution plants, which in this example are the first, third, fourth, and fifth water distribution plants.

[0056] The first water purification plant is connected by pipelines to the first, third, and fourth water distribution plants, and the second water purification plant is connected by pipelines to the fifth water distribution plant.

[0057] The third tier corresponds to road stations installed in, for example, ordinary households. In this example, road stations 1-1 and 1-2 are connected to the first water distribution plant, road station 3-1 is connected to the third water distribution plant, road stations 4-1, 4-2, and 4-3 are connected to the fourth water distribution plant, and road stations 5-1, 5-2, and 5-3 are connected to the fifth water distribution plant by pipelines.

[0058] The inspector in charge of the No. 1 Water Purification Plant, the No. 1 Water Distribution Plant, and the No. 3 Water Distribution Plant is Operator A.

[0059] The inspector in charge of the No. 2 Water Purification Plant, the No. 4 Water Distribution Plant, and the No. 5 Water Distribution Plant is Operator B.

[0060] The inspector in charge of road stations 1-1, 1-2, 4-1, 4-2, and 4-3 is operator C.

[0061] The inspector in charge of road stations 3-1, 5-1, 5-2, and 5-3 is Operator D.

[0062] In this example, the definition information d can be a hierarchical connection relationship diagram as shown in FIG.

[0063] For example, abnormality information b detected by operator A inspecting the third water distribution plant is shared by the operator of the first water purification plant connected to the upper hierarchical side of the third water distribution plant, and the operator inspecting the road station 3-1 connected to the lower hierarchical side. The operator of the first water purification plant is operator A himself, and the operator of the road station 3-1 is operator D. Therefore, abnormality information b detected by operator A inspecting the third water distribution plant is shared between operator A and operator D.

[0064] As another example, abnormality information b detected by operator D inspecting road station 5-1 is shared by an operator inspecting the fifth water distribution plant connected to the upper hierarchical side of road station 5-1 and an operator inspecting the second water purification plant connected to the upper hierarchical side of the fifth water distribution plant. The operator of road station 5-1 is operator D, and the operators of the fifth water distribution plant and the second water purification plant are both operator B. Therefore, abnormality information b detected by operator D inspecting road station 5-1 is shared between operator B and operator D.

[0065] It is preferable to express the definition information d in a hierarchical structure diagram as in FIG. 3, since this not only makes it easy to define the connection relationships but also makes it visually easy to understand.

[0066] Next, a second specific example will be described with reference to FIG.

[0067] FIG. 4 is a control system diagram showing an example of the connection relationships between the various facilities of a water supply and sewerage plant.

[0068] 4, in the illustrated water supply and sewerage plant 310, each piece of equipment such as pumps P1 to P3, valve V, and flow meter F is electrically connected to and controlled by a controller R. For example, the controller R controls the flow rate by increasing or decreasing the number of pumps in operation among the pumps P1 to P3 and by opening and closing the valve opening.

[0069] The pumps P1 to P3 and the valve V are connected via pipelines, and a flow meter F is electrically connected to the valve V. The person inspecting the controller R is operator D, the person inspecting the pumps P1 to P3 is operator A, the person inspecting the valve V is operator C, and the person inspecting the flow meter F is operator B.

[0070] In this example, the definition information d can be a connection relationship diagram showing a control system, as exemplified in Fig. 4. Such a connection relationship diagram can be easily created from a database that clearly indicates the equipment to be controlled and the operators who inspect each piece of equipment. Therefore, in order to easily create the definition information d, it is preferable to create such a database in advance.

[0071] In the case of a water supply and sewerage plant controlled by a control system such as that shown in FIG. 4, if an abnormality is detected in, for example, valve V, operator C inspecting valve V can share abnormality information b with operator D inspecting controller R that controls valve V, operator A inspecting pumps P1 to P3 that are connected to valve V, and operator B inspecting flow meter F that is connected to valve V, according to definition information d created based on the connection diagram shown in FIG.

[0072] As described above, according to the anomaly monitoring system of this embodiment, anomaly information b detected by an operator can be shared not only with the person in charge, but also with other operators inspecting related equipment. This reduces the burden on the person in charge, and makes it possible to reliably discover anomalies and quickly take necessary measures at an early stage without relying on the operator's level of proficiency or skill.

[0073] Second embodiment An abnormality monitoring system to which an abnormality monitoring method according to a second embodiment is applied will be described.

[0074] FIG. 5 is a block diagram showing an example of a schematic configuration of an inspection terminal device and a monitoring terminal device in the anomaly monitoring system according to the second embodiment.

[0075] According to the anomaly monitoring system of this embodiment, even if an anomaly is detected, if the urgency of the anomaly is low, in order to reduce the burden on the person in charge, the person in charge is notified of the anomaly information at a later time rather than being notified of the information each time.

[0076] The inspection terminal device 10 shown in FIG. 5 has the same configuration as the inspection terminal device 10 shown in FIG. 2, so that the same reference numerals as in FIG. 2 are used to denote the respective components to avoid redundant explanation.

[0077] On the other hand, the monitoring terminal device 20a shown in Fig. 5 has a configuration obtained by modifying the monitoring terminal device 20 shown in Fig. 2. Therefore, in the monitoring terminal device 20a, the same components as those in the monitoring terminal device 20 are given the same reference numerals. In the following, the same components will not be described repeatedly, and only the differences from the monitoring terminal device 20 will be described.

[0078] The monitoring terminal device 20a has a notification timing management section 23a in place of the anomaly information sharing facility determination section 23 in the monitoring terminal device 20, and a notification timing information database 24a in place of the definition information database 24.

[0079] The notification timing information database 24a stores timing information i that defines the timing at which the abnormality information b transmitted from the inspection terminal device 10 and received by the monitoring terminal transmitting / receiving unit 22 should be notified.

[0080] For example, some water supply and sewerage plants have equipment with standby machines. Equipment with standby machines usually does not need to respond immediately when an abnormality occurs, so the timing information i can be set to notify all abnormalities at once when the number of abnormalities that have occurred reaches a predetermined number, or to notify periodically, such as once a day.

[0081] The notification timing management unit 23 a includes a notification unit 231 , a notification date and time registration unit 232 , an anomaly information management unit 233 , and a memory 234 .

[0082] The anomaly information management unit 233 manages the timing for notifying the anomaly information b, the position information a, and the time information g received by the monitoring terminal transmitting / receiving unit 22, based on the timing information i stored in the notification timing information database 24a.

[0083] The notification unit 231 operates the monitoring terminal output unit 21 in accordance with the timing managed by the anomaly information management unit 233, and outputs the anomaly information b, location information a, and time information g received by the monitoring terminal transceiver unit 22, thereby notifying the operator in charge (operator B in the example shown in Figure 5).

[0084] For example, the monitoring terminal output unit 21 can be realized by a display or a speaker, and can notify the operator in charge of the abnormality information b, the position information a, and the time information g by displaying the position information a and the time information g as characters or images on the display, and by outputting the audio information f contained in the abnormality information b from the speaker.

[0085] The notification date and time registration unit 232 writes and registers in the memory 234 the date and time when the notification unit 231 operated the monitoring terminal output unit 21, i.e., the date and time when the abnormality information b, the position information a, and the time information g were notified to the operator.

[0086] The anomaly information management unit 233 can determine the timing at which the anomaly information b, location information a, and time information g received by the monitoring terminal transceiver unit 22 are notified not only based on the timing information i, but also taking into consideration the date and time registered in the memory 234.

[0087] As described above, according to the anomaly monitoring system of this embodiment, even if an anomaly is detected, if the urgency is low, the person in charge is not notified each time, but rather, for example, when the number of anomaly occurrences reaches a predetermined number, a notification is made collectively, or periodically, such as once a day. This reduces the burden on the person in charge.

[0088] (Third embodiment) An abnormality monitoring system to which an abnormality monitoring method according to the third embodiment is applied will be described.

[0089] According to the anomaly monitoring system of this embodiment, the person in charge can grasp not only the presence or absence of anomalies but also the inspection status of each piece of equipment.

[0090] FIG. 6 is a block diagram showing an example of a schematic configuration of an inspection terminal device and a monitoring terminal device in the anomaly monitoring system according to the third embodiment.

[0091] The inspection terminal device 10b and the monitoring terminal device 20b shown in Fig. 6 have configurations that are modifications of the inspection terminal device 10 and the monitoring terminal device 20 shown in Fig. 2, respectively. Therefore, in the inspection terminal device 10b and the monitoring terminal device 20b, the same components as those in the inspection terminal device 10 and the monitoring terminal device 20 are given the same reference numerals. In the following, a duplicated description of these same components will be avoided, and only differences will be described.

[0092] The inspection terminal device 10b differs from the inspection terminal device 10 in that the behavior information recording unit 11 further includes an inspection status detection unit 115.

[0093] The inspection status detection unit 115 detects the status of inspection performed on the equipment (hereinafter referred to as "inspection status"), generates inspection status information j indicating the contents of the inspection status, and outputs it to the memory 114. The inspection status information j can include information on the contents of the inspection, the progress of the inspection, and the like.

[0094] When such inspection status information j is output to the memory 114, the position information a from the position detection unit 112, the time information g from the time identification unit 113, and, if any, the voice information f from the voice acquisition unit 111 are also output to the memory 114. These pieces of information are recorded in association with each other in the memory 114.

[0095] The inspection terminal transmitting / receiving unit 13 acquires the inspection status information j, the position information a, the time information g, and, if any, the voice information f from the memory 114, and transmits them to the monitoring terminal device 20b.

[0096] The monitoring terminal device 20b differs from the monitoring terminal device 20 in that the anomaly information sharing facility determination unit 23 and the definition information database 24 are omitted.

[0097] The monitoring terminal device 20 b receives, at the monitoring terminal transmitting / receiving unit 22 , the inspection status information j, the position information a, the time information g, and, if any, the voice information f transmitted from the inspection terminal transmitting / receiving unit 13 .

[0098] The monitoring terminal transmitting / receiving unit 22 outputs the received information a, j, and g to the monitoring terminal output unit 21.

[0099] The monitoring terminal output unit 21 is for outputting the information a, j, and g output from the monitoring terminal transmitting / receiving unit 22, and can be realized by, for example, a display or a speaker. This allows the monitoring terminal output unit 21 to display the inspection status information j, the position information a, and the time information g as characters or images on the display, and to output audio information f, if any, from the speaker. This allows the operator B, who is the person in charge, to grasp the equipment that was inspected, the time when the inspection was performed, the inspection status, etc.

[0100] The monitoring terminal transceiver unit 22 can also transmit the received information, namely, inspection status information j, location information a, time information g, and, if any, audio information f, to an inspection terminal device 10b operated by an operator other than operator A (operator C in the example shown in FIG. 6).

[0101] As a result, the inspection status information j, location information a, time information g, and, if any, audio information f are received by the inspection terminal transceiver unit 13 of the inspection terminal device 10b operated by an operator other than operator A (operator C in the example shown in Figure 6), and are output as text, images, or audio from the inspection terminal output unit 16, so that operator C, who is other than operator A, can also understand the equipment that was inspected, the time the inspection was performed, the inspection status, etc.

[0102] As described above, according to the anomaly monitoring system of this embodiment, even in cases where inspection work is performed simultaneously by multiple operators, such as in a water supply and sewerage plant, the person in charge can share the inspection status of each facility with relevant parties in real time.

[0103] (Fourth embodiment) An abnormality monitoring system to which an abnormality monitoring method according to the fourth embodiment is applied will be described.

[0104] According to the anomaly monitoring system of this embodiment, an operator can grasp information about anomalies that have been detected in the past by other operators with respect to the equipment that the operator is currently inspecting.

[0105] FIG. 7 is a block diagram showing an example of a schematic configuration of an inspection terminal device and a monitoring terminal device in the abnormality monitoring system according to the fourth embodiment.

[0106] The inspection terminal device 10c shown in Fig. 7 has a configuration obtained by modifying the inspection terminal device 10 shown in Fig. 2. Therefore, in the inspection terminal device 10c, the same components as those in the inspection terminal device 10 are given the same reference numerals to avoid redundant explanation, and only the differences will be described.

[0107] The inspection terminal transmitting / receiving unit 13 periodically transmits the abnormality information b, the position information a, and the time information g output from the behavior information recording unit 11 to the monitoring terminal device 20c.

[0108] The monitoring terminal device 20c includes a monitoring terminal transmitting / receiving unit 22, an abnormality history management database 24c, and an abnormality information history management unit .

[0109] If there is no abnormality in the equipment being inspected, the inspection terminal transceiver unit 13 of the inspection terminal device 10c periodically transmits location information a and time information g, but if an abnormality occurs in the equipment being inspected, the location information a and time information g are transmitted together with abnormality information b.

[0110] The monitoring terminal transmitting / receiving unit 22 receives such information transmitted from the inspection terminal transmitting / receiving unit 13, and outputs the received information to the anomaly information history management unit 26.

[0111] The abnormality information history management unit 26 includes an abnormality information input unit 261 and an abnormality information extraction unit 262 .

[0112] When the information received by the monitoring terminal transmitting / receiving unit 22 includes the abnormality information b, the abnormality information input unit 261 inputs the abnormality information b to the abnormality history management database 24c in association with the position information a and time information g that were also received. As a result, the abnormality information b is stored in the abnormality history management database 24c in association with the position information a and time information g.

[0113] When the information received by the monitoring terminal transceiver unit 22 does not include abnormality information b, the abnormality information extraction unit 262 extracts the abnormality information b stored in association with the location information a included in the received information in chronological order from the abnormality history management database 24c by referring to the time information g, and outputs the extracted abnormality information b to the monitoring terminal transceiver unit 22.

[0114] The monitoring terminal transceiver unit 22 transmits the abnormality information b extracted in chronological order by the abnormality information extraction unit 262 to the inspection terminal device 10c that transmitted the information to the monitoring terminal transceiver unit 22, i.e., the inspection terminal device 10c that is located at the location specified by the location information a.

[0115] In this inspection terminal device 10c, the inspection terminal transmitting / receiving unit 13 receives the anomaly information b extracted in chronological order and transmitted from the monitoring terminal transmitting / receiving unit 22. The inspection terminal transmitting / receiving unit 13 further outputs the received anomaly information b and time information g to the inspection terminal output unit 16. The inspection terminal output unit 16 displays the anomaly information b extracted in chronological order.

[0116] In this way, an operator who is an inspector (operator A in the example shown in FIG. 7) can grasp the history of abnormality information b that was detected by other operators in the past for the equipment he is currently inspecting. This allows even an operator with little experience to efficiently determine whether the current situation is abnormal or not, and can also be used to improve skills in determining abnormalities.

[0117] As described above, the abnormality monitoring system 1 of this embodiment enables an operator to grasp abnormality information b that was previously detected by another operator for the equipment that the operator is currently inspecting.

[0118] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
