Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration of an equipment inspection support system 1 according to a first embodiment of the present invention. The equipment inspection support system 1 according to the present embodiment is a system that supports determination of inspection work based on an appropriate response policy for failures that occur in a plurality of equipment 40s. The equipment 40 is, for example, electric power equipment or communication equipment that constitutes social infrastructure.

The equipment inspection support system 1 is broadly divided into an equipment inspection support device 10, an equipment diagnosis device 20, and a management terminal device 30.

The equipment diagnosis device 20 is connected to the equipment inspection support device 10 so as to be communicable via a communication network such as the Internet. The equipment diagnosis device 20 is an information processing device that acquires information indicating the state of a plurality of equipment 40 and diagnoses whether or not an abnormality (failure) has occurred in the equipment 40 based on the acquired information.

The information indicating the state of the plurality of equipment 40 is, for example, an image obtained by capturing the image of the equipment 40, recorded data obtained by recording the sound generated from the equipment 40, or a measurement obtained by measuring the state of the equipment 40 with a sensor (measuring device). Data etc. The measurement data is, for example, the temperature at a predetermined location of the equipment 40, or the current or voltage in the electric circuit included in the equipment 40. The equipment diagnostic device 20 uses the information indicating the state of the equipment 40 as a camera for capturing an image of the equipment 40, a microphone for inputting a sound generated from the equipment 40, a sensor for measuring the state of the equipment 40, or the like. Therefore, it can be obtained via the communication network.

The equipment diagnostic apparatus 20 determines whether or not an abnormality has occurred in the equipment 40 based on the information indicating the state of the equipment 40 acquired as described above and a predetermined diagnostic standard. Since a well-known technique can be applied to the method of determining whether or not an abnormality has occurred in the equipment 40 by the equipment diagnostic apparatus 20, detailed description thereof will be omitted in the present embodiment. The equipment diagnosis device 20 transmits information indicating the state of the equipment 40 to the equipment inspection support device 10 including a determination result of whether or not an abnormality has occurred in the equipment 40. The function of the equipment diagnosis device 20 may be mounted on the equipment inspection support device 10.

The management terminal device 30 is an information processing device such as a personal computer, and is communicably connected to the equipment inspection support device 10. The management terminal device 30 is, for example, when a user (manager or worker of the equipment 40, etc.) inputs information to the equipment inspection support device 10, or the content of the information output by the user from the equipment inspection support device 10. It is a device used as a user interface when confirming. The management terminal device 30 includes a display screen 31 that displays information input to the equipment inspection support device 10 or information output from the equipment inspection support device 10.

The equipment inspection support device 10 is, for example, an information processing device such as a server, and specifically, a device such as the information processing device 900 illustrated in FIG. 8 to be described later. The equipment inspection support device 10 includes an acquisition unit 11, a determination unit 12, a generation unit 13, a display control unit 14, and a storage unit 15. The acquisition unit 11, the determination unit 12, the generation unit 13, and the display control unit 14 are, in order, examples of acquisition means, determination means, generation means, and display control means.

The storage unit 15 is a non-volatile storage device such as the RAM (Random Access Memory) 903 or the hard disk 904 illustrated in FIG. 8, for example. The storage unit 15 stores equipment attribute information 151, abnormality occurrence information 152, and inspection work information 155, which will be described later.

The acquisition unit 11 acquires information indicating the state of the equipment 40 and the abnormality occurrence information 152 indicating the determination result of whether or not an abnormality has occurred in the equipment 40 from the equipment diagnosis device 20. The acquisition unit 11 stores the acquired abnormality occurrence information 152 in the storage unit 15. The abnormality occurrence information 152 includes the captured image 153 and the measurement data 154.

The captured image 153 is an image obtained by capturing the equipment 40 with, for example, a visible light camera or an infrared camera. The captured image 153 includes a result of determining whether or not an abnormality has occurred on the surface of the equipment 40 by analyzing the image captured by the equipment 40. More specifically, the captured image 153 represents the occurrence of scratches or cracks on the surface of the equipment 40. The captured image 153 also represents the state of adhesion of a liquid such as oil or water on the surface of the equipment 40. The type of the liquid adhering to the surface of the equipment 40 can be discriminated from the captured image using the infrared rays of a plurality of wavelengths, for example, by utilizing the difference in the absorption characteristics of the infrared rays of different wavelengths depending on the type of the liquid.

The measurement data 154 is, for example, recorded data obtained by recording the sound generated from the equipment 40 using a microphone. The measurement data 154 is, for example, measurement data obtained by measuring the state of the equipment 40 (for example, the temperature at a predetermined location, the current or the voltage in the electric circuit included in the equipment 40, etc.) with a sensor (measuring device). The measurement data 154 includes a result of determining whether or not an abnormal noise is generated from the equipment 40 by analyzing the above-mentioned recorded data. The measurement data 154 also includes a result of determining whether or not the equipment 40 is in an abnormal state by analyzing the measurement data regarding temperature, current, voltage, and the like.

The determination unit 12 determines the priority for inspecting the individual equipment 40 based on the abnormality occurrence information 152 and the equipment attribute information 151. That is, the determination unit 12 determines the priority using the abnormality occurrence information 152 and the equipment attribute information 151 and the criteria as described later for determining the priority.

The equipment attribute information 151 is information representing the attributes of the individual equipment 40, for example, information created in advance by the manager of the equipment 40 or the like and stored in the storage unit 15.

The equipment attribute information 151 represents, for example, a place (position) where the equipment 40 is installed as an attribute of the equipment 40. The place where the equipment 40 is installed can be represented by, for example, latitude and longitude. The equipment attribute information 151 may also include the characteristics of the place where the equipment 40 is installed. Location features include topographical features such as, for example, along rivers and coasts, or in the mountains, or ground hardness. The characteristics of the place may also include characteristics related to use such as whether or not it is a densely populated residential area, whether or not it is adjacent to an agricultural land, and whether or not it is an industrial area.

The equipment attribute information 151 represents the importance of the equipment 40 as an attribute of the equipment 40 or, for example, in people's lives. The importance of the equipment 40 is, for example, the degree of influence of a certain equipment 40 in which a failure has occurred on people's living environment. For example, when a failure occurs in a certain facility 40, the wider the area where a power failure may occur, the higher the importance of the facility 40. Or, for example, if the surface of a piece of equipment 40 is damaged and the liquid used by that piece of equipment 40 leaks, the more toxic the liquid is, and the more populous the area around the piece of equipment 40 is. It can be said that the importance of the equipment 40 is higher.

For example, with respect to a certain equipment 40, the abnormality occurrence information 152 indicates an abnormality in a distribution system such as a transformer, and the equipment attribute information 151 indicates that the equipment 40 is of high importance (for example, a wide range of power outages occur due to a failure of the equipment 40). It shall indicate that it may occur). In this case, the determination unit 12 sets a high priority for inspecting the equipment 40.

Alternatively, for example, for a given equipment 40, the anomaly information 152 indicates that a non-toxic liquid such as water is leaking, and the equipment attribute information 151 is less important for the equipment 40 (eg, the equipment 40). Even if the function of the above is stopped, it is unlikely that a serious event such as a power outage will occur). In this case, the determination unit 12 sets a low priority for inspecting the equipment 40.

Further, the determination unit 12 calculates an abnormality rate indicating the degree of abnormality from the difference between the state of the equipment 40 represented by the abnormality occurrence information 152 and the state of the equipment 40 in the normal state, and the above-mentioned is based on the calculated abnormality rate. The priority for inspecting the installed equipment 40 may be determined. That is, the determination unit 12 sets the higher the priority for inspecting the equipment 40, the higher the abnormality rate is.

For example, the determination unit 12 determines the abnormality rate from the difference between the temperature of the predetermined location indicated by the abnormality occurrence information 152 and the temperature of the predetermined location when the equipment 40 is operating normally with respect to the equipment 40. calculate. However, it is assumed that the temperature of the predetermined location when the equipment 40 is operating normally is included in the equipment attribute information 151.

Alternatively, for example, the determination unit 12 determines the current or voltage in the electric circuit of the equipment 40 indicated by the abnormality occurrence information 152 and the current or voltage in the electric circuit when the equipment 40 is operating normally with respect to the equipment 40. The abnormality rate is calculated from the difference between. However, it is assumed that the current or voltage in the electric circuit when the equipment 40 is operating normally is included in the equipment attribute information 151.

The determination unit 12 may calculate the above-mentioned abnormality rate as, for example, a ratio of the above-mentioned difference to a predetermined reference value. The reference value is, for example, a value set in advance by the manager of the equipment 40 or the like, and is included in the equipment attribute information 151. The reference value may be, for example, a value indicating the permissible range of the state of the equipment 40, which may be considered that the equipment 40 is operating normally (it cannot be determined that the equipment 40 has a failure).

For example, it is assumed that the temperature of a predetermined portion of the equipment 40 is around 30 degrees in a state where a certain equipment 40 is operating normally. Then, based on the temperature of the place where the equipment 40 is installed, the load condition of the operation of the equipment 40, etc., the temperature of the predetermined place is up to 40 degrees, within the permissible range where the equipment 40 can be regarded as operating normally. There is. Then, when the temperature of the predetermined place becomes 40 degrees or more, it can be considered that the equipment 40 has a failure. In this case, the determination unit 12 calculates the abnormality rate of the equipment 40 as 100% when the temperature of the predetermined portion of the equipment 40 indicated by the abnormality occurrence information 152 is 40 degrees or higher. Further, in the case of this example, when the temperature of the predetermined portion of the equipment 40 is 30 degrees and 35 degrees, the determination unit 12 calculates the abnormality rate of the equipment 40 as 0% and 50%, respectively. When the temperature of the predetermined portion of the equipment 40 is 30 degrees or less, the determination unit 12 may calculate the abnormality rate as 0% because there is no abnormal heat generation at the predetermined portion of the equipment 40. The determination unit 12 may calculate the abnormality rate based on the area where oil leakage, cracks, etc. occur in the equipment 40, for example. More specifically, the determination unit 12 may calculate the abnormality rate based on the ratio of the detected area to the maximum value of the allowable area for oil leakage and cracking.

The determination unit 12 may also adjust the above-mentioned abnormality rate based on the degree of influence of the equipment 40 in which the failure has occurred on the living environment of people. For example, in the above example, the determination unit 12 makes the calculation standard of the abnormality rate stricter as the importance of the equipment 40 is higher (has a greater influence on the living environment), and calculates the abnormality rate as the importance of the equipment 40 is lower. You may loosen the standard. More specifically, for example, when the importance of the equipment 40 is high, the determination unit 12 calculates the abnormality rate as 100% when the temperature of the predetermined location indicated by the abnormality occurrence information 152 is 35 degrees or higher. When the importance of the equipment 40 is low, the abnormality rate may be calculated as 100% when the temperature of the predetermined location indicated by the abnormality occurrence information 152 is 45 degrees or higher.

The generation unit 13 generates inspection work information 155 indicating the inspection work of the equipment 40 based on the priority of inspecting the individual equipment 40 determined by the determination unit 12 and the equipment attribute information 151. That is, the generation unit 13 generates the inspection work information 155 by using the priority and equipment attribute information 151 and the criteria as described later for generating the inspection work information 155. The inspection work information includes the inspection route 156 and the inspection item 157. The details of the method in which the generation unit 13 generates the inspection work information 155 will be described later.

The display control unit 14 displays the abnormality occurrence information 152 acquired by the acquisition unit 11, the abnormality rate calculated by the determination unit 12, and the inspection work information 155 generated by the generation unit 13 on the display screen of the management terminal device 30. Displayed at 31. However, the management terminal device 30 is an example of a display device.

FIG. 2 is a diagram illustrating an embodiment in which the display control unit 14 according to the present embodiment displays the abnormality occurrence information 152 and the inspection work information 155 on the display screen 31. As illustrated in FIG. 2, the display screen 31 includes an equipment name display window 311, a measurement data display window 312, an abnormality rate display window 313, a captured image display window 314, an inspection route display window 315, and an inspection item display window 316. Includes. The mode in which the display control unit 14 displays on the display screen 31 is not limited to the mode illustrated in FIG. For example, the display control unit 14 may display at least one of the plurality of windows described above on the display screen 31, or display information different from the information displayed in the windows described above on the display screen 31. May be good.

The display control unit 14 displays on the equipment name display window 311 the names of the equipment 40 for which information is to be displayed on the measurement data display window 312, the abnormality rate display window 313, and the captured image display window 314. The abnormality occurrence information 152 includes an identifier of the equipment 40 in which the abnormality has occurred, and the equipment attribute information 151 includes the name of the equipment 40 for each identifier.

The display control unit 14 displays the measurement data 154 related to the equipment 40 whose name is displayed in the equipment name display window 311 in the measurement data display window 312. In the example shown in FIG. 2, the display control unit 14 displays a graph representing the measurement data 154. The display control unit 14 displays, for example, a graph showing the time transition of the temperature at a predetermined position of the equipment 40 or a graph showing the time transition of the current or voltage in the electric circuit included in the equipment 40 on the measurement data display window 312. .. The display control unit 14 may, for example, display a graph or the like showing the value of the brightness of the captured image with respect to the wavelength component such as infrared rays captured by the equipment 40 on the measurement data display window 312.

The display control unit 14 may display a sentence or a table representing the measurement data 154 in the measurement data display window 312. The display control unit 14 may also display the analysis result of the measurement data 154 on the measurement data display window 312.

The display control unit 14 displays the abnormality rate related to the equipment 40 calculated as described above by the determination unit 12 in the abnormality rate display window 313. In the example shown in FIG. 2, the display control unit 14 displays the abnormality rate for the two items A and B by a graph and a numerical value. However, items A and B represent abnormality detection items in the equipment 40, and specifically, for example, temperature, current, voltage, scratch or crack occurrence status, liquid adhesion status, abnormal noise generation status, etc. Represents. The display control unit 14 is not limited to two items related to the abnormality rate displayed in the abnormality rate display window 313.

The display control unit 14 displays the captured image 153 in the captured image display window 314. In the example shown in FIG. 2, the display control unit 14 displays the captured image 153 of the equipment 40 in which the surface is scratched or cracked. The display control unit 14 may also display the analysis result of the captured image 153 on the captured image display window 314.

The display control unit 14 determines the above-mentioned abnormality occurrence information 152 and the like to be displayed on the equipment name display window 311, the measurement data display window 312, the abnormality rate display window 313, and the captured image display window 314 as described above by the determination unit 12. The equipment 40 with the highest priority is displayed while being switched in order. For example, the display control unit 14 displays the above-mentioned abnormality occurrence information 152 or the like regarding a certain equipment 40 for a predetermined time, and then switches to and displays the abnormality occurrence information 152 or the like regarding the next equipment 40.

The display control unit 14 displays the inspection route 156 generated by the generation unit 13 on the inspection route display window 315 on the display screen 31.

FIG. 3 is a diagram showing a first example of a mode in which the display control unit 14 according to the present embodiment displays the inspection route 156 on the inspection route display window 315. The inspection route 156 in the example shown in FIG. 3 represents an inspection route related to the equipment 40 in a relatively narrow area such as an urban area. In this case, the equipment 40 is, for example, electric power equipment such as a transformer installed on a utility pole or the like, or communication equipment such as a base station.

In the inspection route 156 illustrated in FIG. 3, the priorities of "◎", "○", and "△" to be inspected by the determination unit 12 are determined to be "high", "medium", and "low" in order. Represents equipment 40. In the example shown in FIG. 3, there are four, five, and eight facilities 40 whose inspection priorities are determined to be “high”, “medium”, and “low”, respectively.

In this case, for example, the generation unit 13 targets four facilities 40 having a priority of "high" to be inspected by a worker, and another facility 40 having a priority of "medium" and "low". Decide to exclude from the targets to be inspected by workers. Then, the generation unit 13 generates the inspection path 156 so that the equipment 40 to be inspected can be inspected most efficiently. More specifically, the inspection route 156 represents, for example, the shortest route when a worker patrols the equipment 40 to be inspected.

The generation unit 13 solves, for example, the traveling salesman problem based on the map information indicating the positions of the four equipments 40 having the inspection priority of "high" and the roads in the vicinity of the equipment 40 indicated by the equipment attribute information 151. The algorithm is used to generate the inspection path 156. However, it is assumed that the map information is stored in the storage unit 15.

For example, when the equipment having the priority of "medium" exists on the shortest path when the worker patrols the equipment having the priority of "high" to be inspected, the generation unit 13 has the priority of "medium". The inspection path 156 may be generated to indicate that the equipment is also inspected.

FIG. 4 is a diagram showing a second example of a mode in which the display control unit 14 according to the present embodiment displays the inspection route 156 on the inspection route display window 315. The inspection route 156 in the example shown in FIG. 4 represents an inspection route for the equipment 40 in an area wider than the area shown in FIG. In this case, the equipment 40 is, for example, a substation facility or the like.

In the example shown in FIG. 4, there are 5, 9, and 10 facilities 40 whose inspection priorities are determined to be "high", "medium", and "low", respectively. In the example shown in FIG. 4, the determination unit 12 sets the priority higher as the equipment 40 is closer to the sea and the equipment 40 is closer to the river. The reason is that the closer the equipment 40 is to the sea or river, the greater the influence of the substance leaked due to the occurrence of the obstacle on the living environment of water pollution through the sea or river. Further, the closer the equipment 40 is to the sea or river, the more easily it is affected by flood damage such as inundation.

Similar to the case of the example shown in FIG. 3, the generation unit 13 is based on the positions of the five equipment 40s having the inspection priority of “high” and the map information in the vicinity of the equipment 40 indicated by the equipment attribute information 151. , Generates inspection path 156.

The display control unit 14 displays the inspection item 157 generated by the generation unit 13 in the inspection item display window 316 on the display screen 31.

FIG. 5 is a diagram illustrating an embodiment in which the display control unit 14 according to the present embodiment displays the inspection item 157 on the inspection item display window 316. The inspection item 157 in the example shown in FIG. 5 includes the names of the four facilities 40 having high priority to be inspected and the inspection items for each of the facilities 40 in the case where the inspection path 156 is the example shown in FIG. show.

The generation unit 13 generates an inspection item 157 for each equipment 40 based on the abnormality occurrence information 152. In the example shown in FIG. 5, the inspection item 157 indicates "a state of cracks on the surface of the equipment and oil leakage" and "heat generation points" as inspection items for "equipment # 0001". In this case, the generation unit 13 has the inspection item 157 as described above based on the abnormality occurrence information 152 indicating that the equipment surface is cracked, oil leaked, and the temperature abnormality has occurred in the “equipment # 0001”. To generate.

Further, in the example shown in FIG. 5, the inspection item 157 indicates "presence or absence of foreign matter adhering to the electric circuit" and "presence or absence of disconnection of the cable" as inspection items for "equipment # 0032". In this case, the generation unit 13 refers to the abnormality occurrence information 152 indicating that the current or voltage abnormality of the electric circuit has occurred in the “equipment # 0032”. The generation unit 13 also refers to the equipment attribute information 151 indicating that an abnormality in the current or voltage of the electric circuit may occur due to a short circuit due to adhesion of foreign matter to the electric circuit or a disconnection of the cable. .. Then, the generation unit 13 generates the inspection item 157 having the above-mentioned contents based on the abnormality occurrence information 152 and the equipment attribute information 151. As described above, when the equipment attribute information 151 includes information indicating the association between the abnormality generated in the equipment 40 and the event considered to be the cause of the abnormality, the generation unit 13 is based on the equipment attribute information 151. The inspection item 157 showing the detailed contents may be generated.

Further, when a plurality of items are abnormal in a certain facility 40, the generation unit 13 generates inspection items 157 only for items that satisfy the criteria regarding importance (highly important), and satisfies the criteria. For items that are not (less important), inspection item 157 may not be generated. However, items of high importance are items that lead to events that have a large impact on the living environment, such as power outages and environmental pollution. More specifically, for example, in a certain facility 40, when a voltage abnormality causes a power failure and a temperature abnormality does not cause a power failure, the generation unit 13 may generate the inspection item 157 only for the voltage abnormality. ..

Next, the operation (processing) of the equipment inspection support system 1 according to the present embodiment will be described in detail with reference to the flowchart of FIG.
