For example, when a failure occurs in multiple facilities that constitute a social infrastructure, it is required to minimize the impact on people's lives as much as possible by taking efficient measures (inspection and repair work) with limited human resources. The response policy for a failure that occurs in a facility is usually decided manually. However, due to a misjudgment by the facility manager who decided the response policy for the failure, an inappropriate response to the failure may be taken, resulting in a significant impact on people's lives. One example of an inappropriate response to a failure is, for example, a delay (postponement) in the inspection of a facility that has a large impact (high importance) on people's lives, and the priority of inspecting the facility may not be optimal in the inspection work indicated by the response policy. Although the above-mentioned Patent Documents 1 and 2 can be expected to have a certain degree of effect of appropriately indicating the status of a failure that occurs in a facility, they cannot solve the problem of determining the inspection work of the facility based on an appropriate response policy.

The main object of the present invention is to provide an equipment inspection support system etc. that enables the determination of inspection work based on an appropriate response policy for a fault that occurs in equipment.

An equipment inspection support system according to one embodiment of the present invention comprises an acquisition means for acquiring abnormality occurrence information representing the occurrence status of abnormalities for each of a plurality of pieces of equipment, a determination means for determining a priority for the inspection of the equipment based on the abnormality occurrence information and attributes of the equipment, and a generation means for generating inspection work information representing inspection work for the equipment based on the priority and attributes of the equipment.

In another aspect of achieving the above object, an equipment inspection support method according to one embodiment of the present invention involves using an information processing device to acquire abnormality occurrence information representing the occurrence of abnormalities for each of a plurality of pieces of equipment, determining a priority for the inspection of the equipment based on the abnormality occurrence information and attributes of the equipment, and generating inspection work information representing inspection work for the equipment based on the priority and attributes of the equipment.

In addition, in a further aspect of achieving the above-mentioned object, an equipment inspection support program according to one embodiment of the present invention is a program for causing a computer to execute an acquisition process for acquiring abnormality occurrence information representing the occurrence status of abnormalities for each of a plurality of pieces of equipment, a determination process for determining a priority for the inspection of the equipment based on the abnormality occurrence information and attributes of the equipment, and a generation process for generating inspection work information representing inspection work for the equipment based on the priority and attributes of the equipment.

Furthermore, the present invention can also be realized by a computer-readable, non-volatile recording medium on which such an equipment inspection support program (computer program) is stored.

According to the present invention, an equipment inspection support system is obtained that determines inspection work based on an appropriate response policy for a fault that occurs in equipment.

Below, the embodiment of the present invention is described in detail with reference to the drawings.

First Embodiment
1 is a block diagram showing the 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 this embodiment is a system that supports the determination of inspection work based on an appropriate response policy for failures that occur in a plurality of pieces of equipment 40. The equipment 40 is, for example, a power facility or a communication facility that constitutes a social infrastructure.

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

The equipment diagnosis device 20 is communicatively connected to the equipment inspection support device 10 via a communication network such as the Internet. The equipment diagnosis device 20 is an information processing device that acquires information representing the state of multiple pieces of equipment 40 and diagnoses whether an abnormality (fault) has occurred in the equipment 40 based on the acquired information.

The information representing the state of the multiple pieces of equipment 40 is, for example, images of the equipment 40, or audio data of sounds generated from the equipment 40, or measurement data measuring the state of the equipment 40 by a sensor (measuring device). The measurement data is, for example, the temperature at a specific location of the equipment 40, or the current or voltage in an electric circuit provided in the equipment 40. The equipment diagnosis device 20 is capable of acquiring this information representing the state of the equipment 40 via a communication network from a camera that captures an image of the equipment 40, a microphone that inputs sounds generated from the equipment 40, or a sensor that measures the state of the equipment 40.

The equipment diagnosis device 20 determines whether or not an abnormality has occurred in the equipment 40 based on the information representing the state of the equipment 40 acquired as described above and a predetermined diagnosis criterion. Since the method by which the equipment diagnosis device 20 determines whether or not an abnormality has occurred in the equipment 40 can be performed by applying well-known technology, a detailed description thereof will be omitted in this embodiment. The equipment diagnosis device 20 transmits information representing the state of the equipment 40, including the determination result of whether or not an abnormality has occurred in the equipment 40, to the equipment inspection support device 10. The functions of the equipment diagnosis device 20 may be implemented in the equipment inspection support device 10.

The management terminal device 30 is an information processing device such as a personal computer, and is connected to the equipment inspection support device 10 so that it can communicate with it. The management terminal device 30 is a device used as a user interface, for example, when a user (such as a manager or worker of the equipment 40) inputs information to the equipment inspection support device 10, or when the user checks the contents of the information output from the equipment inspection support device 10. The management terminal device 30 is provided with a display screen 31 that displays the information input to the equipment inspection support device 10 or the information output from the equipment inspection support device 10.

The equipment inspection support device 10 is an information processing device such as a server, and specifically, an information processing device such as the information processing device 900 illustrated in FIG. 8 described below. 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 memory unit 15. The acquisition unit 11, the determination unit 12, the generation unit 13, and the display control unit 14 are examples of an acquisition means, a determination means, a generation means, and a display control means, respectively.

The storage unit 15 is, for example, a non-volatile storage device such as a RAM (Random Access Memory) 903 or a hard disk 904 illustrated in FIG. 8. 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, from the equipment diagnosis device 20, information representing the state of the equipment 40 and abnormality occurrence information 152 representing the determination result as to whether or not an abnormality has occurred in the equipment 40. The acquisition unit 11 stores the acquired abnormality occurrence information 152 in the memory unit 15. The abnormality occurrence information 152 includes captured images 153 and measurement data 154.

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

The measurement data 154 is, for example, audio recording data obtained by recording sounds generated from the equipment 40 using a microphone. Alternatively, the measurement data 154 is, for example, measurement data obtained by measuring the state of the equipment 40 (for example, the temperature at a specific location, or the current or voltage in an electrical circuit provided in the equipment 40, etc.) using a sensor (measuring device). The measurement data 154 includes the result of determining whether or not an abnormal sound is generated from the equipment 40 by analyzing the above-mentioned audio recording data. Alternatively, the measurement data 154 includes the result of determining whether or not the equipment 40 is in an abnormal state by analyzing measurement data related to temperature, current, voltage, etc.

The determination unit 12 determines the priority of inspecting each piece of equipment 40 based on the abnormality occurrence information 152 and the equipment attribute information 151. That is, the determination unit 12 determines the priority by using the abnormality occurrence information 152, the equipment attribute information 151, and a criterion for determining the priority, as described below.

The equipment attribute information 151 is information that represents the attributes of each equipment 40, and is information that is created in advance, for example, by an administrator of the equipment 40, and stored in the memory unit 15.

The equipment attribute information 151 represents, as an attribute of the equipment 40, for example, the location (position) where the equipment 40 is installed. The location where the equipment 40 is installed can be represented, for example, by latitude and longitude. The equipment attribute information 151 may also include characteristics of the location where the equipment 40 is installed. The location characteristics include, for example, characteristics related to the topography, such as being along a river or a coast, being in the mountains, or the hardness of the ground. The location characteristics may also include characteristics related to the use, such as whether or not it is a residential area, whether or not it is adjacent to farmland, whether or not it is an industrial area, etc.

The facility attribute information 151 represents the attributes of the facility 40, or, for example, the importance of the facility 40 in people's lives. The importance of the facility 40 is, for example, the degree of impact that a certain facility 40 that has failed has on people's living environment. For example, if a certain facility 40 fails, the wider the area in which a power outage may occur, the higher the importance of the facility 40. Or, for example, if the surface of a certain facility 40 is damaged and a liquid used by the facility 40 leaks, the more toxic the liquid is and the larger the population in the vicinity of the facility 40, the higher the importance of the facility 40.

For example, assume that, for a certain piece of equipment 40, the abnormality occurrence information 152 indicates an abnormality in a power distribution system such as a transformer, and the equipment attribute information 151 indicates that the importance of the equipment 40 is high (for example, a failure of the equipment 40 may cause a widespread power outage). In this case, the determination unit 12 sets a high priority for inspecting the equipment 40.

Alternatively, for example, with respect to a certain facility 40, the abnormality occurrence information 152 indicates that a non-toxic liquid such as water is leaking, and the facility attribute information 151 indicates that the importance of the facility 40 is low (for example, even if the facility 40 stops functioning, there is a low possibility that a serious event such as a power outage will occur). In this case, the determination unit 12 sets the priority of inspecting the facility 40 to low.

The determination unit 12 may also calculate an anomaly rate representing the degree of anomaly from the difference between the state of the equipment 40 represented by the anomaly occurrence information 152 and the normal state of the equipment 40, and determine the priority of inspecting the above-mentioned equipment 40 based on the calculated anomaly rate. That is, the higher the anomaly rate, the higher the determination unit 12 sets the priority of inspecting the equipment 40.

For example, the determination unit 12 calculates the anomaly rate for a certain piece of equipment 40 from the difference between the temperature at a specific location indicated by the anomaly occurrence information 152 and the temperature at the specific location when the equipment 40 is operating normally. However, it is assumed that the temperature at the specific location when the equipment 40 is operating normally is included in the equipment attribute information 151.

Alternatively, for example, the determination unit 12 calculates the anomaly rate for a certain piece of equipment 40 from the difference between the current or voltage in the electric circuit of the equipment 40 indicated by the anomaly occurrence information 152 and the current or voltage in the electric circuit when the equipment 40 is operating normally. 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 anomaly rate, for example, as a ratio of the above-mentioned difference to a predetermined reference value. The reference value is a value set in advance by, for example, an administrator of the equipment 40, and is included in the equipment attribute information 151. The reference value may be, for example, a value indicating an acceptable range of the state of the equipment 40, which may be regarded as indicating that the equipment 40 is operating normally (it cannot be determined that a fault has occurred in the equipment 40).

For example, when a certain equipment 40 is operating normally, the temperature of a specific location of the equipment 40 is approximately 30 degrees. Then, taking into account the air temperature at the installation location of the equipment 40 and the load status of the equipment 40, the temperature of the specific location up to 40 degrees is within the allowable range in which the equipment 40 can be considered to be operating normally. Then, when the temperature of the specific location becomes 40 degrees or higher, it can be considered that a fault has occurred in the equipment 40. In this case, when the temperature of the specific location of the equipment 40 indicated by the abnormality occurrence information 152 is 40 degrees or higher, the determination unit 12 calculates the abnormality rate of the equipment 40 to be 100%. Also, in this example, when the temperature of the specific location of the equipment 40 is 30 degrees and 35 degrees, the determination unit 12 calculates the abnormality rate of the equipment 40 to be 0% and 50%, respectively. Note that when the temperature of the specific location of the equipment 40 is 30 degrees or lower, there is no abnormal heat generation in the specific location of the equipment 40, so the determination unit 12 may calculate the abnormality rate to be 0%. Alternatively, for example, the determination unit 12 may calculate the abnormality rate based on an area where an oil leak, a crack, or the like occurs in the equipment 40. More specifically, the determination unit 12 may calculate the abnormality rate based on a ratio of the detected area to a maximum allowable area for the oil leak or the crack.

The determination unit 12 may also adjust the above-mentioned abnormality rate based on the degree of impact of the equipment 40 in which the failure has occurred on people's living environment. For example, in the above example, the determination unit 12 may set stricter calculation criteria for the abnormality rate as the importance of the equipment 40 is higher (the impact on the living environment is greater), and may set lenient calculation criteria for the abnormality rate as the importance of the equipment 40 is lower. More specifically, the determination unit 12 may calculate the abnormality rate to be 100% when the temperature of the specified location indicated by the abnormality occurrence information 152 is 35 degrees or higher when the importance of the equipment 40 is high, and may calculate the abnormality rate to be 100% when the temperature of the specified location indicated by the abnormality occurrence information 152 is 45 degrees or higher when the importance of the equipment 40 is low.

The generation unit 13 generates inspection work information 155 representing the inspection work of the equipment 40 based on the priority of inspecting each 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 using the priority, the equipment attribute information 151, and criteria for generating the inspection work information 155 as described below. The inspection work information includes an inspection route 156 and inspection items 157. Details of how 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 31 of the management terminal device 30. However, the management terminal device 30 is an example of a display device.

2 is a diagram illustrating an example of a manner in which the display control unit 14 according to this embodiment displays abnormality occurrence information 152 and 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. Note that the manner in which the display control unit 14 displays on the display screen 31 is not limited to the manner illustrated in FIG. 2. The display control unit 14 may, for example, display at least one of the above-mentioned windows on the display screen 31, or may display information different from the information displayed in the above-mentioned windows on the display screen 31.

The display control unit 14 displays in the equipment name display window 311 the name of the equipment 40 for which information is to be displayed in 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 occurred, and the equipment attribute information 151 includes the name of the equipment 40 for each identifier.

The display control unit 14 displays, in the measurement data display window 312, the measurement data 154 relating to the equipment 40 whose name is displayed in the equipment name display window 311. 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, in the measurement data display window 312, for example, a graph representing the time progression of the temperature at a specific location of the equipment 40, or a graph representing the time progression of the current or voltage in an electric circuit provided in the equipment 40. The display control unit 14 may also display, in the measurement data display window 312, for example, a graph representing the luminance value of an image of the equipment 40 relative to wavelength components such as infrared light.

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

The display control unit 14 displays the abnormality rate for the equipment 40, calculated by the determination unit 12 as described above, in the abnormality rate display window 313. In the example shown in FIG. 2, the display control unit 14 displays the abnormality rates for two items, item A and item B, by graphs and numerical values. However, item A and item B represent the detected abnormality items in the equipment 40, specifically representing, for example, temperature, current, voltage, the occurrence of scratches or cracks, the adhesion of liquid, the occurrence of abnormal noise, etc. Note that the number of items related to the abnormality rate displayed by the display control unit 14 in the abnormality rate display window 313 is not limited to two.

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 equipment 40 having scratches or cracks on its surface. The display control unit 14 may also display the analysis results of the captured image 153 in the captured image display window 314.

The display control unit 14 switches and displays the above-mentioned abnormality occurrence information 152, etc., displayed in 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 in order from the equipment 40 with the highest priority determined as described above by the determination unit 12. For example, the display control unit 14 displays the above-mentioned abnormality occurrence information 152, etc., related to a certain equipment 40 for a predetermined period of time, and then switches and displays the abnormality occurrence information 152, etc., related to the next equipment 40.

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

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

In the inspection route 156 illustrated in FIG. 3, "◎", "◯", and "△" represent facilities 40 whose inspection priorities have been determined to be "high", "medium", and "low" by the determination unit 12, respectively. In the example illustrated in FIG. 3, there are four, five, and eight facilities 40 whose inspection priorities have been determined to be "high", "medium", and "low", respectively.

In this case, for example, the generation unit 13 determines that four pieces of equipment 40 with an inspection priority of "high" are to be inspected by the worker, and excludes other pieces of equipment 40 with a priority of "medium" and "low" from the targets of inspection by the worker. The generation unit 13 then generates an inspection route 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 for the worker to patrol the equipment 40 to be inspected.

The generation unit 13 generates the inspection route 156 using, for example, an algorithm for solving the traveling salesman problem, based on the locations of the four pieces of equipment 40 with a "high" inspection priority indicated by the equipment attribute information 151 and map information indicating roads near the equipment 40. However, it is assumed that the map information is stored in the storage unit 15.

For example, when a worker patrols equipment with a "high" priority and there is equipment with a "medium" priority on the shortest route, the generation unit 13 may generate an inspection route 156 that indicates that the equipment with a "medium" priority will also be inspected.

Figure 4 is a diagram showing a second example of how the display control unit 14 according to this embodiment displays an inspection route 156 in the inspection route display window 315. The inspection route 156 in the example shown in Figure 4 represents an inspection route for equipment 40 in an area larger than the area shown in Figure 3. In this case, the equipment 40 is, for example, a substation facility.

In the example shown in FIG. 4, there are 5, 9, and 10 pieces of equipment 40 whose inspection priorities have been determined to be "high," "medium," and "low," respectively. In the example shown in FIG. 4, the determination unit 12 sets a higher priority for equipment 40 the closer it is to the sea and the closer it is to a river. This is because the closer the equipment 40 is to the sea or a river, the greater the impact on the living environment of water pollution via the sea or river due to substances leaking due to a malfunction. Also, the closer the equipment 40 is to the sea or a river, the more susceptible it is to the effects of flooding and other flooding damage.

As in the example shown in Figure 3, the generation unit 13 generates an inspection route 156 based on the locations of five pieces of equipment 40 with a "high" inspection priority indicated by the equipment attribute information 151 and map information in the vicinity of the equipment 40.

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.

Figure 5 is a diagram illustrating an example of how the display control unit 14 according to this embodiment displays inspection items 157 in the inspection item display window 316. In the example shown in Figure 5, the inspection items 157 indicate the names of four pieces of equipment 40 with high priority to be inspected when the inspection route 156 is the example shown in Figure 3, and the inspection items for each of those pieces of equipment 40.

The generation unit 13 generates inspection items 157 for each piece of equipment 40 based on the abnormality occurrence information 152. In the example shown in Fig. 5, the inspection items 157 indicate "condition of cracks and oil leaks on the equipment surface" and "location of heat generation" as inspection items for "equipment #0001". In this case, the generation unit 13 generates the inspection items 157 with the above-mentioned contents based on the abnormality occurrence information 152 indicating that cracks and oil leaks on the equipment surface, and temperature abnormalities have occurred in "equipment #0001".

5, the inspection item 157 indicates "whether or not a foreign object is attached to the electric circuit" and "whether or not a cable breakage has occurred" as the inspection item for "equipment #0032". In this case, the generation unit 13 refers to the abnormality occurrence information 152 indicating that an abnormality in the current or voltage of the electric circuit has occurred in "equipment #0032". The generation unit 13 also refers to the equipment attribute information 151 indicating that a short circuit caused by the attachment of a foreign object to the electric circuit or a cable breakage may cause an abnormality in the current or voltage of the electric circuit. Then, the generation unit 13 generates the inspection item 157 with the above-mentioned contents based on the abnormality occurrence information 152 and the equipment attribute information 151. In this way, the generation unit 13 may generate the inspection item 157 indicating more detailed contents based on the equipment attribute information 151 when, for example, the equipment attribute information 151 includes information indicating an association between an abnormality that has occurred in the equipment 40 and an event that is considered to be the cause of the abnormality.

In addition, when abnormalities occur in multiple items in a certain facility 40, the generation unit 13 may generate inspection items 157 only for items that satisfy a criterion for importance (high importance), and may not generate inspection items 157 for items that do not satisfy the criterion (low importance). However, items of high importance are, for example, items that lead to events that have a large impact on the living environment, such as power outages or environmental pollution. More specifically, for example, in a certain facility 40, when voltage abnormalities are a cause of power outages but temperature abnormalities are not a cause of power outages, the generation unit 13 may generate inspection items 157 only for voltage abnormalities.

Next, with reference to the flowchart in Figure 6, the operation (processing) of the equipment inspection support system 1 in this embodiment will be explained in detail.

The acquisition unit 11 acquires abnormality occurrence information 152 for each of the multiple pieces of equipment 40 from the equipment diagnosis device 20 (step S101). The determination unit 12 calculates an abnormality rate for each piece of equipment 40 based on the equipment attribute information 151 and the abnormality occurrence information 152 (step S102). The determination unit 12 determines the priority of inspecting each piece of equipment 40 based on the calculated abnormality rate (step S103).

The generation unit 13 generates an inspection route 156 for the worker to patrol based on the priority of inspecting each piece of equipment 40 determined by the determination unit 12 and the location of each piece of equipment 40 indicated by the equipment attribute information 151 (step S104). The generation unit 13 generates inspection items 157 for each piece of equipment 40 to be inspected based on the abnormality occurrence information 152 (step S105).

The display control unit 14 displays the name, measurement data 154, abnormality rate, and captured image 153 for each facility 40 in the facility name display window 311, measurement data display window 312, abnormality rate display window 313, and captured image display window 314 on the display screen 31, switching between the facilities 40 with the highest priority at a predetermined time interval (step S106). The display control unit 14 displays the inspection route 156 and inspection items 157 generated by the generation unit 13 in the inspection route display window 315 and inspection item display window 316 on the display screen 31 (step S107), and the entire process is completed.

The equipment inspection support system 1 according to this embodiment can determine inspection work based on an appropriate response policy for a fault that occurs in the equipment. This is because the equipment inspection support system 1 determines a priority for the inspection of the equipment 40 based on the abnormality occurrence information 152 and the equipment attribute information 151 for each of the multiple pieces of equipment 40, and generates inspection work information 155 based on the determined priority and the equipment attribute information 151.

Below, the effects achieved by the equipment inspection support system 1 of this embodiment are explained in detail.

For example, when a failure occurs in multiple facilities that make up a social infrastructure, it is necessary to minimize the impact on people's lives as much as possible by responding efficiently with limited human resources. The response policy for a failure that occurs in a facility is usually decided manually. However, due to an error in judgment by the facility manager who decided the response policy for the failure, an inappropriate response to the failure may be taken, resulting in a significant impact on people's lives. One example of an inappropriate response to a failure is when the inspection of a facility that has a large impact (high importance) on people's lives is delayed, and the inspection work indicated by the response policy does not prioritize the inspection of the facility. In other words, when a failure occurs in a facility, the challenge is to support the decision on the inspection work of the facility based on an appropriate response policy.

In response to such issues, the equipment inspection support system 1 according to this embodiment includes an acquisition unit 11, a determination unit 12, and a generation unit 13, and operates, for example, as described above with reference to Figures 1 to 6. That is, the acquisition unit 11 acquires abnormality occurrence information 152 representing the occurrence status of an abnormality for each of the multiple pieces of equipment 40. The determination unit 12 determines a priority for the inspection of the equipment based on the abnormality occurrence information 152 and the equipment attribute information 151. Then, the generation unit 13 generates inspection work information 155 representing the inspection work for the equipment based on the priority and the equipment attribute information 151.

That is, the equipment inspection support system 1 according to this embodiment determines the priority for inspecting the equipment 40 based on the occurrence of an abnormality in the equipment 40 and the impact of the equipment 40 on people's lives, and determines the inspection work information 155 based on the priority and the location of the equipment 40, etc. As a result, the equipment inspection support system 1 according to this embodiment can determine inspection work based on an appropriate response policy for a fault that has occurred in the equipment 40.

Furthermore, the equipment inspection support system 1 according to this embodiment calculates an anomaly rate based on the difference between the state of the equipment 40 represented by the anomaly occurrence information 152 and the normal state of the equipment 40, and the degree of impact that the equipment 40 in which a fault has occurred has on the living environment. Then, the equipment inspection support system 1 determines the priority of inspecting the equipment 40 based on the calculated anomaly rate. This allows the equipment inspection support system 1 to more appropriately determine the inspection work for the equipment 40.

As illustrated in Figures 2 to 5, the equipment inspection support system 1 according to this embodiment displays abnormality occurrence information 152, inspection work information 155, and abnormality rate on the display screen 31. The equipment inspection support system 1 then switches between displaying the abnormality occurrence information 152 and the abnormality rate on the display screen 31 in order of the equipment 40 with the highest inspection priority. This allows the equipment inspection support system 1 to support the manager or worker of the equipment 40 in appropriately recognizing the status of the equipment 40 in which an abnormality has occurred, taking into account its importance.

Furthermore, the equipment inspection support system 1 according to this embodiment sets a higher inspection priority the closer the equipment 40 is to the sea and the closer the equipment 40 is to a river, taking into account the impact of a failure of the equipment 40 on environmental pollution. Furthermore, the equipment inspection support system 1 sets a higher inspection priority the larger the area that will be affected by a failure of the equipment 40. This allows the equipment inspection support system 1 to determine inspection work that minimizes the impact on people's lives as much as possible.

In addition, the equipment inspection support system 1 according to this embodiment generates an inspection route 156 that represents the shortest route for an operator to travel around the equipment 40 that requires inspection. This enables the equipment inspection support system 1 to support the realization of efficient inspection work of the equipment 40 using limited human resources.

Furthermore, when multiple abnormalities occur in the equipment 40, the equipment inspection support system 1 according to this embodiment includes in the inspection work information 155 inspection items 157 related to abnormalities whose degree of impact on the living environment meets the criteria. In other words, the equipment inspection support system 1 does not include in the inspection work information 155 inspection items 157 related to abnormalities whose degree of impact on the living environment does not meet the criteria (i.e., low importance). In this way, the equipment inspection support system 1 narrows down the inspection items to those with high importance, thereby supporting the realization of efficient inspection work of the equipment 40 using limited human resources.

In addition, the equipment inspection support system 1 according to this embodiment generates inspection items 157 based on equipment attribute information 151 indicating an association between an abnormality that has occurred in the equipment 40 and an event that is considered to be the cause of the abnormality. This enables the equipment inspection support system 1 to support the realization of accurate inspection work for the equipment 40.

Second Embodiment
7 is a block diagram showing a configuration of an equipment inspection support system 50 according to a second embodiment of the present invention. The equipment inspection support system 50 includes an acquisition unit 51, a determination unit 52, and a generation unit 53. However, the acquisition unit 51, the determination unit 52, and the generation unit 53 are examples of an acquisition means, a determination means, and a generation means, respectively.

The acquisition unit 51 acquires abnormality occurrence information 600 that indicates the occurrence status of an abnormality for each of the multiple facilities 60. However, the facilities 60 are, for example, power facilities or communication facilities similar to the facilities 40 according to the first embodiment, and the abnormality occurrence information 600 is, for example, information similar to the abnormality occurrence information 152 according to the first embodiment. The acquisition unit 51 may acquire the abnormality occurrence information 600 via a device such as the equipment diagnosis device 20, similar to the acquisition unit 11 according to the first embodiment.

The determination unit 52 determines a priority 521 for equipment inspection based on the abnormality occurrence information 600 and the equipment attributes 520. The equipment attributes 520 are, for example, information similar to the equipment attribute information 151 according to the first embodiment. The determination unit 52 determines the priority 521 in a manner similar to that of the determination unit 12 according to the first embodiment.

The generation unit 53 generates inspection work information 530 representing the inspection work of the equipment based on the priority 521 and the equipment attributes 520. The inspection work information 530 is, for example, information similar to the inspection work information 155 according to the first embodiment, and may include information such as the inspection route 156 and inspection items 157 according to the first embodiment.

The equipment inspection support system 50 according to this embodiment can determine inspection work based on an appropriate response policy for a fault that occurs in the equipment. This is because the equipment inspection support system 50 determines a priority 521 for the inspection of the equipment 60 based on the abnormality occurrence information 600 for each of the multiple pieces of equipment 60 and the equipment attributes 520, and generates inspection work information 530 based on the determined priority 521 and the equipment attributes 520.
