DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, a management system and a management method according to an embodiment will be described in detail with reference to the accompanying drawings.

[0011] Embodiment 1 1 is a diagram illustrating an example of the configuration of a water treatment plant system according to the first embodiment. The water treatment plant system 1 according to the first embodiment includes a management system 10. The management system 10 is a system that centralizes maintenance management support that supports the maintenance management of equipment in a water treatment plant, which is a water treatment plant, and operation management support that supports the operation management of equipment in the water treatment plant, and is capable of implementing maintenance management support and operation management support for equipment in the water treatment plant.

[0012] In the management system 10, an operation management support database device 20, a maintenance management support database device 30, a terminal 40, a server 50, a mechanical equipment controller 60, and a water treatment equipment controller 70 are each connected so as to be able to communicate with the management system 10. That is, the management system 10 can exchange information with the operation management support database device 20, the maintenance management support database device 30, the terminal 40, the server 50, the mechanical equipment controller 60, and the water treatment equipment controller 70. Communication between each of the above devices and the management system 10 may be wireless or wired.

[0013] The management system 10 includes an operation management support device 11, a maintenance management support device 12, and a display unit 13.

[0014] The maintenance management support device 12 is a device that supports the maintenance management of equipment in a water treatment plant. The maintenance management support device 12 performs a deterioration diagnosis analysis, i.e., a deterioration diagnosis that determines the type and degree of deterioration for each deterioration diagnosis item, based on sensor information, which is status data that indicates the status of each piece of equipment in the water treatment plant. More specifically, the sensor information can be considered as status data that indicates the status of the equipment or parts that make up the equipment that make up each piece of equipment in the water treatment plant.

[0015] The maintenance management support device 12 transmits the diagnosis result of the deterioration diagnosis and the sensor information to the display unit 13 for display. The maintenance management support device 12 stores the diagnosis result as a deterioration diagnosis result in the maintenance management storage unit 31 of the maintenance management support database device 30. In addition, the maintenance management support device 12 transmits the diagnosis result to the operation management support device 11 as a deterioration diagnosis result.

[0016] The operation management support device 11 supports the operation management of each piece of equipment in the water treatment plant based on information on the type of deterioration and the degree of deterioration obtained based on the diagnosis results of the deterioration diagnosis in the maintenance management support device 12. Details of the type of deterioration and the degree of deterioration will be described later. The management system 10 according to the first embodiment can detect an abnormality in the equipment based on the type of deterioration, the magnitude of the degree of deterioration, and the importance. This eliminates the need for workers to patrol each piece of equipment in the water treatment plant to check for any abnormalities occurring in the equipment, thereby reducing the burden of maintenance management work on the workers.

[0017] Furthermore, the operation management support device 11 simulates an equipment operation method for continuing operation of the water treatment plant equipment in accordance with the status of the deterioration type and the deterioration level, based on the type of deterioration, the magnitude of the deterioration level, and the importance level. More specifically, the operation management support device 11 simulates an equipment operation method for continuing operation of the equipment in which deterioration has occurred in accordance with the status of the determined deterioration type and the deterioration level. The operation management support device 11 displays the equipment operation method, which is the simulation result, on the display unit 13 and presents the equipment operation method of the simulation result to the operator. This allows the equipment operator to consider how to respond when an abnormality occurs in the equipment based on the equipment operation method of the simulation result presented by the operation management support device 11, and can quickly and easily respond when an abnormality occurs in the equipment.

[0018] The operation management support database device 20 includes an operation management storage unit 21 that stores various information related to the operation management of the facilities of the water treatment plant as a database. The operation management storage unit 21 stores, for example, equipment operation history and monitoring and control information.

[0019] The equipment operation history is a history of the operation of the water treatment plant equipment performed by an operator in the past, i.e., a history of information on the operation method of the water treatment plant equipment during past operation. The equipment operation history includes appropriate operation of the water treatment plant equipment performed by a skilled operator.

[0020] The monitoring and control information is monitoring information on the status of the water treatment plant equipment, such as water level, water quality, and energy, during past operation of the equipment.

[0021] Information other than the above may also be stored in the operation management storage unit 21 of the operation management support database device 20. Although the operation management support database device 20 is shown as a single device in Fig. 1, the operation management support database device 20 may be part of the operation management support device 11 or part of the management system 10. Furthermore, the operation management support database device 20 may be divided into multiple devices.

[0022] The maintenance management support database device 30 includes a maintenance management storage unit 31 that stores various information related to the maintenance management of the water treatment plant equipment as a database. The maintenance management storage unit 31 stores, for example, information on equipment inspection work, equipment renewal plans, and deterioration diagnosis results, including the type and degree of deterioration and importance.

[0023] The inspection work information is information including the details of the inspection work for each device corresponding to the deterioration level.

[0024] The importance level is the importance level of the equipment constituting the facilities in the water treatment plant, and is stored in advance in the maintenance management storage unit 31. The importance level is determined by the operators of the water treatment plant.

[0025] The maintenance management storage unit 31 of the maintenance management support database device 30 may also store information other than the above. Although the maintenance management support database device 30 is depicted as a single device in FIG. 1, the maintenance management support database device 30 may be part of the maintenance management support device 12 or part of the management system 10. Furthermore, the maintenance management support database device 30 may be separated into multiple devices. Furthermore, although the maintenance management support database device 30 is depicted as a single device in FIG. 1, the maintenance management support database device 30 and the operation management support database device 20 may be included in a single database device.

[0026] In the example shown in FIG. 1, a water treatment plant, which is a plant to be managed by the management system 10, includes mechanical equipment and water treatment equipment.

[0027] The mechanical equipment includes a distribution board 61 and equipment 63. The equipment 63 includes a motor 64, a pump 65, and a blower 66. The distribution board 61 includes an equipment diagnostic device 62, which is a diagnostic device that performs deterioration diagnosis on each device in the equipment 63 using sensor information indicating the state of the motor 64, the pump 65, and the blower 66. The distribution board 61 and the equipment 63 are provided with sensors (not shown) that detect the state of the distribution board 61 and the equipment 63. The sensors transmit the detection results as sensor information to the mechanical equipment controller 60. The mechanical equipment controller 60 transmits the received sensor information to the management system 10.

[0028] The water treatment facility includes a primary sedimentation tank 71, a biological reaction tank 73, and a final sedimentation tank 76. The biological reaction tank 73 includes a filtration membrane 74. The primary sedimentation tank 71, the biological reaction tank 73, and the final sedimentation tank 76 are each equipped with a sensor 72, a sensor 75, and a sensor 77, respectively, that detect the state of the primary sedimentation tank 71, the biological reaction tank 73, and the final sedimentation tank 76. The sensors 72, 75, and 77 include, for example, a water quality sensor, a dissolved oxygen meter, a water thermometer, an aeration rate meter, and a water / sludge flow meter. The sensor information obtained by these sensors includes, for example, aeration rate, electrical conductivity, ammonia concentration, dissolved oxygen, and water temperature. The sensor 75 includes, for example, a transmembrane pressure meter, a filtration flow meter, a water thermometer, or the like that detects the state of the filtration membrane 74 and outputs an analog signal. For example, the sensor information obtained by the sensor 75 includes at least one of the transmembrane pressure meter, the filtration flow rate, and the water temperature of the filtration membrane 74. The sensors 72, 75, and 77 transmit the sensor information, which is the detection result, to the water treatment facility controller 70. The water treatment facility controller 70 transmits the received sensor information to the management system 10.

[0029] Hereinafter, when there is no need to distinguish between the sensors 72, 75, and 77 and the above-mentioned sensors not shown, they will be referred to as sensors. The sensors are capable of outputting sensor information, which is the detection result, as an electrical signal to another device.

[0030] The configuration of the water treatment plant shown in FIG. 1 is an example, and the facilities of the water treatment plant and the devices that make up each facility are not limited to the example shown in FIG. 1. For example, if a sufficient amount of solid-liquid separation can be performed using the filtration membrane 74, the final settling tank 76 does not necessarily need to be installed. The number of sensors shown in FIG. 1 is also not limited to the example shown in FIG. 1. In the example shown in FIG. 1, each device and each sensor in each facility transmits information to the management system 10 via a controller such as the mechanical equipment controller 60 or the water treatment equipment controller 70. However, this is not limiting. Each device and each sensor in each facility may transmit information directly to the management system 10 without going through a controller, or may transmit information to the management system 10 via the terminal 40 or another device not shown.

[0031] The terminal 40 is a portable terminal that can be carried by a worker, such as a tablet, smartphone, or personal computer. The terminal 40 transmits sensor information or diagnostic result information received from each device and each sensor in each facility to the management system 10. The terminal 40 also allows the worker to check the sensor information or diagnostic result information received from each device and each sensor in each facility on the terminal 40. The terminal 40 may also transmit and display the sensor information, diagnostic result information, etc. on a glasses-type display called smart glasses or AR (Augmented Reality) glasses that can be worn by the worker.

[0032] The server 50 can have some or all of the functions of the management system 10 and some of the functions of a diagnostic device, which will be described later. That is, the server 50 can function as part of the management system 10 or as the management system 10. The server 50 can also function as a diagnostic device. The server 50 can be a physical server or a cloud server.

[0033] The mechanical equipment controller 60 is a control device that controls the operation of the equipment by sending control commands to the devices of the equipment facility 63. The mechanical equipment controller 60 also receives sensor information that is the detection result of a sensor installed in the mechanical equipment, and transmits the sensor information to the management system 10. The mechanical equipment controller 60 also receives diagnostic result information that indicates the diagnosis result of an equipment diagnostic device 62 installed in the mechanical equipment from the equipment diagnostic device 62, and transmits the diagnostic result information to the management system 10.

[0034] The water treatment facility controller 70 is a control device that sends control commands to the equipment of the water treatment facility to control the operation of the equipment. The water treatment facility controller 70 also receives sensor information, which is the detection result of sensors installed in the water treatment facility, and transmits the sensor information to the management system 10.

[0035] In general, inspections at plants are carried out periodically. For example, in the case of water treatment plants, traditionally, on-site inspection workers would patrol each facility every day, inspecting it visually, listening, and using their five senses, and recording the inspection results on an inspection sheet. Because water treatment plants have multiple pieces of equipment, including machinery and water treatment equipment, spread across a wide area, inspections require time and effort. Meanwhile, water treatment plants often face challenges in maintaining stable operation and management due to factors such as declining water bill revenues and the retirement of veteran engineers. Furthermore, the likelihood of equipment breakdowns due to facility aging is increasing, while maintenance costs are also on the rise. For these reasons, water treatment plants are seeking labor-saving, manpower-saving, and more efficient maintenance.

[0036] The management system 10 according to the first embodiment can detect abnormalities in equipment using information on the type and degree of deterioration determined based on the results of the deterioration diagnosis, and information on the importance level. This eliminates the need for workers to patrol each piece of equipment in the water treatment plant to check for any abnormalities in the equipment, thereby reducing the burden of maintenance and management work on workers.

[0037] 2 is a diagram showing an example of the configuration of each diagnostic device according to Embodiment 1. As shown in FIG.

[0038] The communication unit 621 communicates with devices external to the device diagnostic device 62 .

[0039] The sensor unit 622 has a sensor that detects the state of each device in the equipment facility 63 , and transmits sensor information indicating the detection results by the sensor to the degradation diagnosis analysis unit 623 and the communication unit 621 .

[0040] The degradation diagnostic analysis unit 623 uses the sensor information to perform degradation diagnostic analysis, that is, degradation diagnosis to estimate the type and degree of degradation in the device.

[0041] The sensor unit 622 includes, as sensors, for example, a current sensor that detects the current of the motor 64, or a current-voltage sensor that detects the current and voltage of the motor 64. The sensor unit 622 also includes a vibration sensor that detects the vibration of the motor 64. Note that a voltage sensor that detects the voltage of the motor 64 may be provided separately.

[0042] The sensor unit 622 also includes, as sensors, for example, a current sensor that detects the current of the pump 65, or a current-voltage sensor that detects the current and voltage of the pump 65. The sensor unit 622 also includes a vibration sensor that detects the vibration of the pump 65. Note that a voltage sensor that detects the voltage of the pump 65 may be provided separately.

[0043] The sensor unit 622 also includes, as a sensor, for example, a current sensor that detects the current of the blower 66, or a current-voltage sensor that detects the current and voltage of the blower 66. The sensor unit 622 also includes a vibration sensor that detects the vibration of the blower 66. Note that a voltage sensor that detects the voltage of the blower 66 may also be provided separately.

[0044] There are no particular restrictions on the specific method of degradation diagnosis performed by the degradation diagnosis analysis unit 623, but for example, a degradation diagnosis method used in a technique called CBM (Condition Based Maintenance) can be used. For example, the degradation diagnosis method may be a method that uses a frequency spectrum of sensor information obtained as time-series data, a method that uses a threshold, or a method that uses machine learning.

[0045] The method using the frequency spectrum involves, for example, determining the frequency spectrum of sensor information obtained as time-series data, calculating a feature in the frequency spectrum, and estimating the type and degree of deterioration based on the feature. The feature is, for example, but is not limited to, a parameter representing the shape of the frequency spectrum or a value at a point in the frequency spectrum that satisfies a specified condition.

[0046] The threshold method estimates the type and degree of degradation by predetermining thresholds corresponding to the type and degree of degradation for the sensor information values. The machine learning method may involve, for example, having an experienced inspector provide the type and degree of degradation as correct answer data for each feature obtained from the sensor information, and then generating a trained model through supervised learning using multiple data sets containing the feature and correct answer data. The feature may be the amplitude or specific frequency components of the sensor information, or the sensor information itself extracted for a certain period of time. When using such a trained model, the degradation diagnosis analysis unit 623 extracts feature values ​​from the sensor information and inputs the extracted feature values ​​into the trained model to obtain an estimated result of the type and degree of degradation. Degradation diagnosis may also be performed using machine learning using clustering, such as the K-means method. The degradation diagnosis method is not limited to the above-described example.

[0047] Here, an example will be described in which amounts indicating the type of degradation and the degree of degradation are calculated as the diagnostic results of the degradation diagnosis by the degradation diagnosis analysis unit 623, and the maintenance management support device 12 calculates the type of degradation and the degree of degradation from the diagnostic results based on the calculated amounts. However, the results of the degradation diagnosis by the degradation diagnosis analysis unit 623 may also be the type of degradation itself and the degree of degradation itself. That is, in the degradation diagnosis by the degradation diagnosis analysis unit 623, amounts indicating the type of degradation and the degree of degradation may be calculated as the diagnostic results, or the type of degradation itself and the degree of degradation itself, which are the final diagnostic results, may be estimated along with the calculation of the amounts indicating the type of degradation and the degree of degradation as the diagnostic results. Furthermore, the degradation diagnosis analysis unit 623 may calculate one diagnostic result using sensor information obtained from one sensor, or may calculate one diagnostic result using multiple pieces of sensor information obtained from multiple sensors.

[0048] The diagnosis result may be obtained for each device such as the motor 64, the pump 65, the blower 66, etc., or for each component constituting the device. For example, diagnosis results may be obtained for each component A and B of the device X. In other words, if the unit for which a diagnosis result is obtained, i.e., the unit for which an estimated result of the degree of deterioration is obtained, is called a deterioration estimation item, the deterioration diagnosis analysis unit 623 will obtain a diagnosis result for each deterioration estimation item.

[0049] The maintenance management support device 12 determines the type of deterioration occurring in the equipment based on the diagnosis results of the deterioration estimation items. That is, the deterioration type is the type of deterioration occurring in the equipment, and is the same as the deterioration estimation items, and can also be said to be the type of abnormality.

[0050] The degradation diagnosis analysis unit 623 outputs diagnosis result information indicating the diagnosis result to the communication unit 621. The communication unit 621 transmits the diagnosis result information and the sensor information to the mechanical equipment controller 60. The mechanical equipment controller 60 transmits the diagnosis result information and the sensor information received from the equipment diagnostic device 62 to the maintenance management support device 12 in the management system 10.

[0051] Next, we will explain the filtration membrane diagnostic device 78. In the configuration shown in Fig. 1, sensor information, which is the detection result of a sensor 75 that detects the state of the filtration membrane 74, is transmitted to the management system 10 via the water treatment facility controller 70, and the management system 10 performs a deterioration diagnostic analysis, i.e., a deterioration diagnosis that estimates the type and degree of deterioration.

[0052] On the other hand, the biological reactor 73 may be configured to include a filtration membrane diagnostic device 78. As shown in FIG. 2 , the filtration membrane diagnostic device 78 includes a communication unit 781, a sensor unit 782, and a degradation diagnostic analysis unit 783. The sensor unit 782 includes, as a sensor, a sensor 75 that detects the state of the filtration membrane 74. The functions and operations of the communication unit 781, the sensor unit 782, and the degradation diagnostic analysis unit 783 are similar to the functions and operations of the communication unit 621, the sensor unit 622, and the degradation diagnostic analysis unit 623 of the equipment diagnostic device 62, respectively, except that the sensor unit 782 includes the sensor 75 that detects the state of the filtration membrane 74, and the degradation diagnostic analysis unit 783 performs degradation diagnosis corresponding to the filtration membrane 74.

[0053] The water treatment facility may also be configured to include a sensor diagnostic device 79. As shown in FIG. 2 , sensor diagnostic device 79 includes a communication unit 791, a sensor unit 792, and a degradation diagnostic analysis unit 793. Sensor unit 792 includes sensors that detect the states of various sensors provided in the water treatment facility. The functions and operations of communication unit 791, sensor unit 792, and degradation diagnostic analysis unit 793 are similar to the functions and operations of communication unit 621, sensor unit 622, and degradation diagnostic analysis unit 623 of equipment diagnostic device 62, respectively, except that sensor unit 792 includes sensors that detect the states of various sensors provided in the water treatment facility, and degradation diagnostic analysis unit 793 performs degradation diagnosis corresponding to the various sensors provided in the water treatment facility.

[0054] Deterioration diagnosis of various sensors can be performed using, for example, a learning device. Taking a water quality sensor as an example, a predicted value is calculated by a learning device that has learned actual measured values ​​from the water quality sensor from the past to the present. If the calculated predicted value differs from the actual measured value by more than a predetermined threshold, it can be determined that the sensor has deteriorated.

[0055] FIG. 3 is a diagram showing an example of a configuration related to the processing of each diagnostic device of the equipment diagnostic device, the filtration membrane diagnostic device, and the biological reactor according to the first embodiment. "Target equipment" in FIG. 3 indicates equipment that is the target of deterioration diagnosis by each diagnostic device. The motor, pump, and blower shown in "target equipment" are equipment that is the target of deterioration diagnosis by the equipment diagnostic device 62. The "filtration membrane" shown in "target equipment" is equipment that is the target of deterioration diagnosis by the filtration membrane diagnostic device 78. The "sensor" shown in "target equipment" is equipment that is the target of deterioration diagnosis by the sensor diagnostic device 79, and is a sensor installed in the primary sedimentation tank 71, the biological reactor 73, and the final sedimentation tank 76.

[0056] "Sensor" in Fig. 3 indicates the sensor from which each diagnostic device acquires sensor information for performing a degradation diagnosis. "Data" shown in Fig. 3 indicates the type of sensor information data used by each diagnostic device for performing a degradation diagnosis. "Degradation diagnosis" shown in Fig. 3 indicates the content of the degradation diagnosis performed by each diagnostic device. Then, an abnormality can be detected based on the content of the degradation diagnosis performed by each diagnostic device.

[0057] For example, if the target device is a motor, the device diagnostic device 62 can acquire current data as sensor information from a current sensor and diagnose the type and level of deterioration of the motor or motor components by analyzing the current data. Furthermore, if the target device is a motor, the device diagnostic device 62 can acquire current data as sensor information from a current sensor, voltage data as sensor information from a voltage sensor, and diagnose the type and level of deterioration of the motor or motor components by analyzing the current data and voltage data. Furthermore, if the target device is a motor, the device diagnostic device 62 can acquire current data as sensor information from a current sensor, voltage data as sensor information from a voltage sensor, and vibration data as sensor information from a vibration sensor, and diagnose the type and level of deterioration of the motor or motor components by analyzing the current data, voltage data, and vibration data.

[0058] That is, the device diagnostic device 62 can diagnose the type and degree of degradation by performing data analysis using only the current data acquired from the current sensor. The device diagnostic device 62 can also diagnose the type and degree of degradation by performing data analysis using the current data acquired from the current sensor and the voltage data acquired from the voltage sensor. The device diagnostic device 62 can also diagnose the type and degree of degradation by performing data analysis using the current data acquired from the current sensor, the voltage data acquired from the voltage sensor, and the vibration data acquired from the vibration sensor. Increasing the types of sensor information used for degradation diagnosis increases the accuracy of the degradation diagnosis, the number of types of degradation that can be diagnosed by the degradation diagnosis, and the number of types of abnormalities that can be diagnosed.

[0059] The same applies when the target equipment is a pump, blower, filtration membrane, or sensor shown in Figure 3, and the equipment diagnostic device 62 can diagnose the type and degree of deterioration of the target equipment or parts of the target equipment using one or more types of sensor information.

[0060] Next, a configuration example of the management system 10 according to the embodiment 1 will be described. Fig. 4 is a diagram showing a configuration example of the management system according to the embodiment 1. The maintenance management support device 12 includes a sensor information acquisition unit 121, a diagnosis result information acquisition unit 122, an analysis unit 123, an update plan creation unit 124, and a maintenance management communication unit 125.

[0061] The sensor information acquisition unit 121 acquires sensor information, which is status data indicating the status of each piece of equipment in the water treatment plant, from each diagnostic device and sensor installed in the equipment of the water treatment plant, such as the mechanical equipment and the water treatment equipment, and transmits the acquired sensor information to the analysis unit 123. That is, the sensor information acquisition unit 121 receives sensor information from each diagnostic device and sensor via each controller, the mechanical equipment controller 60 and the water treatment equipment controller 70, to acquire sensor information indicating the status of the equipment in the water treatment plant and transmits the acquired sensor information to the analysis unit 123. An example of a diagnostic device is the equipment diagnostic device 62.

[0062] The diagnostic result information acquiring unit 122 acquires diagnostic result information indicating the diagnostic results of the deterioration diagnosis performed by the diagnostic devices installed in the equipment of the water treatment plant, such as the mechanical equipment and the water treatment equipment, from each diagnostic device. That is, the diagnostic result information acquiring unit 122 acquires the diagnostic result information from each diagnostic device by receiving the diagnostic result information from each diagnostic device via each controller, the mechanical equipment controller 60 and the water treatment equipment controller 70, and transmits the acquired diagnostic result information to the analyzing unit 123. Note that the diagnostic result information acquiring unit 122 may receive the diagnostic result information from each diagnostic device via the terminal 40. An example of a diagnostic device is the equipment diagnostic device 62.

[0063] The analysis unit 123 includes a degradation diagnosis analysis unit 1231 and a degradation degree calculation unit 1232 .

[0064] The deterioration diagnosis analysis unit 1231 performs deterioration diagnosis based on the sensor information of the sensors 72, 75, and 77 of the water treatment facility among the sensor information acquired by the sensor information acquisition unit 121. The deterioration diagnosis performed by the deterioration diagnosis analysis unit 1231 is similar to the deterioration diagnosis in the equipment diagnosis device 62.

[0065] The deterioration level calculation unit 1232 calculates the type of deterioration and the degree of deterioration for each diagnosis result, i.e., for each degradation diagnosis item, using the diagnosis result information received from the diagnosis result information acquisition unit 122, the diagnosis result information indicating the diagnosis result of the degradation diagnosis analysis unit 1231, and the deterioration level correspondence information indicating the correspondence between the diagnosis result and the degree of deterioration. That is, the deterioration level calculation unit 1232 calculates the type of deterioration and the degree of deterioration for each diagnosis result. The deterioration level correspondence information is determined in advance and stored in the deterioration level calculation unit 1232. Note that, if the diagnosis result (deterioration diagnosis result) is calculated as the type of deterioration and the degree of deterioration themselves, it is not necessary to provide the deterioration level calculation unit 1232. That is, the type of deterioration and the degree of deterioration may be determined based on the diagnosis result of the degradation diagnosis, and the diagnosis result itself may be the type of deterioration and the degree of deterioration.

[0066] The deterioration level correspondence information includes a range of values ​​obtained as a diagnosis result for each deterioration diagnosis item and a deterioration level corresponding to the range. For example, in the deterioration level correspondence information, the deterioration level is expressed in four stages from 0 to 3, where a deterioration level of 0 corresponds to normal, a deterioration level of 1 corresponds to early abnormality, a deterioration level of 2 corresponds to mid-stage abnormality, and a deterioration level of 3 corresponds to terminal abnormality. The deterioration level is not limited to this, and may be expressed in two stages, normal and abnormal, or in five or more stages. Note that, although an example is shown here in which the deterioration diagnosis result is some quantity indicating the deterioration level, as described above, the deterioration diagnosis result may be the deterioration level itself. In this case, the process of calculating the deterioration level is unnecessary. Also, here, it is assumed that the smaller the degree of deterioration, the smaller the value of the deterioration level.

[0067] The deterioration degree calculation unit 1232 transmits the sensor information received from the sensor information acquisition unit 121, the diagnosis result information received from the diagnosis result information acquisition unit 122, the diagnosis result information indicating the diagnosis result by the degradation diagnosis analysis unit 1231, and the deterioration type and deterioration degree calculated by the deterioration degree calculation unit 1232 to the update plan creation unit 124, the display unit 13, and the maintenance management communication unit 125. In addition, the deterioration degree calculation unit 1232 stores various information related to deterioration diagnosis, such as the diagnosis result information received from the diagnosis result information acquisition unit 122, the diagnosis result information indicating the diagnosis result by the degradation diagnosis analysis unit 1231, and the deterioration type and deterioration degree calculated by the deterioration degree calculation unit 1232, as deterioration diagnosis results in the maintenance management storage unit 31 of the maintenance management support database device 30.

[0068] The update plan creation unit 124 creates an update plan for the equipment and parts using the information on the type and degree of deterioration received from the analysis unit 123, and stores the created update plan in the maintenance management storage unit 31 of the maintenance management support database device 30 and transmits it to the display unit 13. In addition, an operator of the water treatment plant can create an equipment update plan based on the sensor information and diagnosis results displayed on the display unit 13, and store the update plan in the maintenance management storage unit 31 of the maintenance management support database device 30.

[0069] The maintenance management communication unit 125 communicates with external devices of the maintenance management support device 12 .

[0070] Next, a description will be given of the configuration of the operation management support device 11. The operation management support device 11 includes a normal state support unit 111, an abnormal state support unit 112, and an operation management communication unit 113.

[0071] The normal state response support unit 111 includes a driving support information analysis unit 1111 .

[0072] The operation support information analysis unit 1111 receives the information on the type of deterioration and the degree of deterioration transmitted from the maintenance management support device 12 via the operation management communication unit 113. When the operation support information analysis unit 1111 determines that there is no abnormality in the equipment based on the information on the type of deterioration and the degree of deterioration transmitted from the maintenance management support device 12, it transmits and stores the current normal operation method of the equipment, i.e., information on the current normal operation of the equipment, as an equipment operation history to the operation management storage unit 21 of the operation management support database device 20. In this way, the current normal operation method of the equipment is stored as an equipment operation history in the operation management storage unit 21 of the operation management support database device 20, making it possible to accumulate know-how on the equipment operation method.

[0073] The abnormality response support unit 112 includes a driving support information analysis unit 1121 and a simulation unit 1122 .

[0074] The operation support information analysis unit 1121 receives the information on the type of deterioration and the degree of deterioration transmitted from the maintenance management support device 12 via the operation management communication unit 113. When the operation support information analysis unit 1121 determines that there is an abnormality in the equipment based on the information on the type of deterioration and the degree of deterioration transmitted from the maintenance management support device 12, the operation support information analysis unit 1121 determines whether to continue operating the equipment or to suspend the equipment based on the type of deterioration and the degree of deterioration acquired from the maintenance management support device 12 and the importance stored in the maintenance management support database device 30.

[0075] When it is determined that the operation of the equipment is to be suspended, the operation support information analysis unit 1121 causes the display unit 13 to display a suspension instruction notice indicating that the operation of the equipment is to be suspended as the operation method of the equipment.

[0076] If it is determined that the operation of the equipment should be continued, the operation support information analysis unit 1121 extracts an equipment operation method for continuing the operation of the equipment under the conditions of the acquired deterioration type and deterioration level from the equipment operation history stored in the operation management storage unit 21 of the operation management support database device 20. The operation support information analysis unit 1121 extracts, from the equipment operation history stored in the operation management storage unit 21, an equipment operation method with conditions similar to the acquired deterioration type, deterioration level, and importance level.

[0077] The simulation unit 1122 acquires information on the type and degree of deterioration transmitted from the maintenance management support device 12 and information on the equipment operation method extracted by the operation support information analysis unit 1121. Based on the acquired information on the type and degree of deterioration, the simulation unit 1122 simulates an equipment operation method for continuing operation of the water treatment plant equipment in the conditions of the acquired type and degree of deterioration that meets predetermined target conditions for water level, water quality, and energy, using water level, water quality, and energy as KPIs (Key Performance Indicators). The equipment operation method for continuing operation of the water treatment plant equipment in the conditions of the acquired type and degree of deterioration can be said to be an equipment operation method for continuing operation of the water treatment plant.

[0078] The operation management communication unit 113 communicates with devices external to the operation management support device 11. The operation management communication unit 113 receives, from the maintenance management communication unit 125, sensor information acquired by the sensor information acquisition unit 121, diagnostic result information acquired by the diagnostic result information acquisition unit 122, diagnostic result information indicating the diagnostic result by the degradation diagnostic analysis unit 1231, and information on the type of degradation and degree of degradation calculated by the degradation degree calculation unit 1232. The operation management communication unit 113 transmits each of these received pieces of information to the normal state response support unit 111 and the abnormal state response support unit 112.

[0079] Next, a configuration example of the terminal 40 according to the first embodiment will be described. Fig. 5 is a diagram showing a configuration example of the terminal according to the first embodiment. The terminal 40 includes an input receiving unit 41, an information acquiring unit 42, a terminal storage unit 43, a terminal communication unit 44, a terminal display unit 45, and a terminal control unit 46.

[0080] The input receiving unit 41 receives input from a user such as a worker.

[0081] The information acquisition unit 42 receives diagnostic result information from diagnostic devices installed in the equipment of the water treatment plant, such as mechanical equipment and water treatment equipment. The information acquisition unit 42 transmits the acquired diagnostic result information to the management system 10 via the terminal communication unit 44.

[0082] The terminal storage unit 43 stores information used to control the terminal 40 and information acquired from outside the terminal 40.

[0083] The terminal communication unit 44 communicates with devices external to the terminal 40 .

[0084] The terminal display unit 45 displays various information within the terminal 40 .

[0085] The terminal control unit 46 controls the operation of the terminal 40 .

[0086] Next, a configuration example of the server 50 according to the first embodiment will be described. FIG. 6 is a diagram illustrating a configuration example of the server according to the first embodiment. The server 50 includes a server storage unit 51, a server communication unit 52, and a server control unit 53. As described above, the server 50 can function as part of the management system 10 or as the management system 10. The server 50 can also function as a degradation diagnosis analysis unit that is part of the diagnostic device. In this case, the server 50 realizes part of the functions of the management system 10 or the diagnostic device by the server storage unit 51, the server communication unit 52, and the server control unit 53. A physical server or a cloud server can be used as the server 50.

[0087] The server storage unit 51 stores information used to control the server 50 and information acquired from outside the server 50.

[0088] The server communication unit 52 communicates with devices external to the server 50 .

[0089] The server control unit 53 controls the operation of the server 50 .

[0090] Next, the operation of the management system 10 according to the first embodiment will be described. Fig. 7 is a flowchart showing an example of management processing of a water treatment facility in the management system according to the first embodiment. In Fig. 7, steps S110 to S130 are processing related to maintenance management support. In Fig. 7, steps S140 to S170 are processing related to operation management support.

[0091] In step S110, the sensor information acquisition unit 121 of the maintenance management support device 12 acquires sensor information, which is status data indicating the status of each piece of equipment in the water treatment plant, from each diagnostic device and sensor installed in the equipment in the water treatment plant, such as the mechanical equipment and the water treatment equipment. The sensor information acquisition unit 121 transmits the acquired sensor information to the analysis unit 123. Then, the process proceeds to step S120.

[0092] Specifically, the sensor information acquisition unit 121 acquires the sensor information of the sensor unit 622 of the equipment diagnostic device 62 via the machine equipment controller 60. The sensor information acquisition unit 121 may acquire the sensor information of the sensor unit 622 of the equipment diagnostic device 62 directly without going through the machine equipment controller 60, or may acquire the sensor information via the terminal 40 or another device not shown.

[0093] Furthermore, sensor information acquisition unit 121 acquires sensor information from sensors 72, 75, and 77 arranged in the water treatment facility via water treatment facility controller 70. Sensor information acquisition unit 121 may acquire the sensor information from sensors 72, 75, and 77 directly without going through water treatment facility controller 70, or may acquire the information via terminal 40 or another device not shown.

[0094] In step S120, the diagnostic result information acquiring unit 122 of the maintenance management support device 12 acquires, from the diagnostic device, diagnostic result information indicating the diagnostic results of the deterioration diagnosis performed by the diagnostic device installed in the equipment of the water treatment plant, such as the mechanical equipment and the water treatment equipment. The diagnostic result information acquiring unit 122 transmits the acquired diagnostic result information to the analysis unit 123. Then, the process proceeds to step S130.

[0095] Specifically, the diagnostic result information acquisition unit 122 acquires diagnostic result information indicating the diagnostic results of the degradation diagnosis performed by the degradation diagnosis analysis unit 623 of the equipment diagnostic device 62 via the mechanical equipment controller 60. The diagnostic result information acquisition unit 122 may acquire the diagnostic result information of the degradation diagnosis analysis unit 623 directly without going through the mechanical equipment controller 60, or may acquire it via the terminal 40 or another device not shown.

[0096] In step S130, the type and degree of deterioration are determined. Specifically, the deterioration diagnosis analysis unit 1231 of the analysis unit 123 performs deterioration diagnosis based on the sensor information of sensors 72, 75, and 77 of the water treatment facility, among the sensor information acquired by the sensor information acquisition unit 121. The deterioration diagnosis performed by the deterioration diagnosis analysis unit 1231 is similar to the deterioration diagnosis in the equipment diagnosis device 62. The deterioration diagnosis analysis unit 1231 transmits diagnosis result information indicating the diagnosis result of the deterioration diagnosis to the deterioration degree calculation unit 1232.

[0097] Then, the deterioration degree calculation unit 1232 determines the type of deterioration and the degree of deterioration for each piece of diagnostic result information, using the diagnostic result information received from the diagnostic result information acquisition unit 122 and the diagnostic result information received from the degradation diagnosis analysis unit 1231, and the deterioration degree correspondence information. The deterioration degree calculation unit 1232 transmits the sensor information received from the sensor information acquisition unit 121, the diagnostic result information received from the diagnostic result information acquisition unit 122, the diagnostic result information indicating the diagnosis result by the degradation diagnosis analysis unit 1231, and information on the type of deterioration and the degree of deterioration calculated by the deterioration degree calculation unit 1232 to the update plan creation unit 124 and the maintenance management communication unit 125.

[0098] The maintenance management communication unit 125 transmits the sensor information, diagnosis result information, degradation type, and degradation level information to the operation management communication unit 113 of the operation management support device 11. Upon receiving the sensor information, diagnosis result information, degradation type, and degradation level information, the operation management communication unit 113 transmits the information to the normal state response support unit 111 and the abnormal state response support unit 112.

[0099] Furthermore, the deterioration degree calculation unit 1232 displays the sensor information, diagnosis result information, and information on the type of deterioration and degree of deterioration on the display unit 13 to present to the worker. Furthermore, the deterioration degree calculation unit 1232 stores the diagnosis result information received from the diagnosis result information acquisition unit 122 and the diagnosis result information indicating the diagnosis result by the deterioration diagnosis analysis unit 1231 as a deterioration diagnosis result in the maintenance management storage unit 31 of the maintenance management support database device 30. Thereafter, the process proceeds to step S140.

[0100] Fig. 8 is a diagram showing an example of degradation diagnosis locations where degradation diagnosis is performed in a motor pump used in the equipment according to the first embodiment. As shown in Fig. 8, in the motor section of motor pump 67, degradation diagnosis location 671 for rotor bar abnormality, degradation diagnosis location 672 for winding abnormality, degradation diagnosis location 673 for bearing abnormality, degradation diagnosis location 674 for torque abnormality, and degradation diagnosis location 675 for misalignment abnormality are exemplified. In addition, in the pump section of motor pump 67, degradation diagnosis location 676 for bearing abnormality, degradation diagnosis location 677 for cavitation abnormality, degradation diagnosis location 678 for impeller abnormality, and degradation diagnosis location 679 for mechanical seal abnormality are exemplified.

[0101] Fig. 9 is a diagram illustrating an example of classification of deterioration levels in the first embodiment. For example, "deterioration levels" are classified into "deterioration level 0," "deterioration level 1," "deterioration level 2," and "deterioration level 3" according to the deterioration state of the device or device component. "State" in Fig. 9 defines the normal state or abnormal state of the device or device component corresponding to the deterioration level.

[0102] For example, "deterioration level 0" corresponds to the case where the state of the equipment or equipment parts is "normal."

[0103] "Deterioration Level 1" corresponds to when the condition of the equipment or equipment parts is an "initial abnormality." An "initial abnormality" is an abnormality that is difficult to detect through inspection based on the five senses. For example, if there is an "initial abnormality" such as a minute scratch on the bearing of a pump, the pump will perform at the same level as a normal product.

[0104] "Deterioration Level 2" corresponds to when the condition of the equipment or equipment parts is "medium-term abnormality." A "medium-term abnormality" is an abnormality where the deterioration of the equipment or equipment parts has progressed beyond an "initial abnormality." For example, if the damage to the bearings of a pump has progressed to a "medium-term abnormality," the pump will start making strange noises. In this case, the pump will not immediately fail and stop, but it is best to refrain from operating it.

[0105] "Deterioration Level 3" corresponds to when the equipment or equipment parts are in an "end-stage abnormality" state. An "end-stage abnormality" is an abnormality in which the equipment or equipment parts have deteriorated more severely than an "intermediate-stage abnormality." For example, if the damage to a pump bearing has progressed to an "end-stage abnormality," there is a risk that the pump will stop working due to end-stage failure of the bearing, and the pump must be stopped immediately.

[0106] Returning to the explanation of Fig. 7, in step S140, the driving support information analysis unit 1111 of the normal state response support unit 111 and the driving support information analysis unit 1121 of the abnormal state response support unit 112 determine whether or not there is an abnormality in the equipment. Specifically, the driving support information analysis unit 1111 of the normal state response support unit 111 and the driving support information analysis unit 1121 of the abnormal state response support unit 112 determine whether or not there is an abnormality in the equipment, that is, whether or not the deterioration level satisfies the conditions corresponding to an abnormality in the equipment, based on the information on the deterioration type and deterioration level received from the maintenance management communication unit 125.

[0107] The driving support information analysis unit 1111 of the normal state response support unit 111 and the driving support information analysis unit 1121 of the abnormal state response support unit 112 determine that there is no abnormality in the equipment when the deterioration level indicated in the deterioration level information received from the maintenance management communication unit 125 is deterioration level 0, as shown in Fig. 9, for example. The driving support information analysis unit 1111 of the normal state response support unit 111 and the driving support information analysis unit 1121 of the abnormal state response support unit 112 determine that there is an abnormality in the equipment when the deterioration level indicated in the deterioration level information received from the maintenance management communication unit 125 is deterioration level 1 to deterioration level 3, as shown in Fig. 9, for example.

[0108] If it is determined that there is an abnormality in the equipment, the result in step S140 is Yes, and the process proceeds to step S150. If it is determined that there is no abnormality in the equipment, the result in step S140 is No, and the process proceeds to step S170. If it is determined that there is no abnormality in the equipment, the driving support information analysis unit 1121 of the abnormality response support unit 112 ends the process.

[0109] Here, we have explained the case where the normal state response support unit 111 and the abnormal state response support unit 112 determine whether or not there is an abnormality in the equipment, but it is also possible to provide an independent component that determines whether or not there is an abnormality in the equipment based on information on the type and degree of deterioration.

[0110] In step S150, an operation method for continuing operation of the equipment in the state of the deterioration type and deterioration level received from the maintenance management communication unit 125 is simulated. First, the operation support information analysis unit 1121 of the abnormality response support unit 112 determines whether to continue operation of the equipment or to suspend operation of the equipment based on the deterioration type, deterioration level, and importance level acquired from the maintenance management support device 12. The operation support information analysis unit 1121 determines whether to continue operation of the equipment or to suspend operation of the equipment based on an operation policy that determines whether to continue operation of the equipment or to suspend operation of the equipment. The operation policy is policy information used by the operation support information analysis unit 1121 when determining whether to continue operation of the equipment or to suspend operation of the equipment based on the deterioration type, deterioration level, and importance level, and is predetermined and stored in the operation support information analysis unit 1121.

[0111] 10 is a diagram illustrating an example of an operation policy corresponding to a type of motor deterioration in the first embodiment. For example, the operation policy when a winding abnormality, which is a short circuit event, occurs is to immediately suspend the operation of the pump. The operation policy when a rotor bar abnormality or misalignment abnormality occurs is to continue operation of the equipment if the deterioration level is lower than a predetermined deterioration level, and to temporarily suspend operation of the equipment if the deterioration level is higher than the predetermined deterioration level.

[0112] The operating policy when torque abnormalities and bearing abnormalities occur is to continue operation of the equipment if the deterioration level is lower than a predetermined deterioration level and the importance level is lower than a predetermined importance level, to temporarily suspend operation of the equipment if the deterioration level is lower than a predetermined deterioration level and the importance level is higher than a predetermined importance level, and to temporarily suspend operation of the equipment if the deterioration level is higher than a predetermined deterioration level.

[0113] 11 is a diagram illustrating an example of an operation policy corresponding to a pump deterioration type in the first embodiment. For example, the operation policy when an impeller abnormality or a cavitation abnormality occurs is to continue operation of the equipment if the deterioration level is lower than a predetermined deterioration level, and to temporarily suspend operation of the equipment if the deterioration level is higher than the predetermined deterioration level.

[0114] The operating policy when a mechanical seal abnormality or a bearing abnormality occurs is to continue operation of the equipment if the deterioration level is lower than a predetermined deterioration level and the importance level is lower than a predetermined importance level, to temporarily suspend operation of the equipment if the deterioration level is lower than a predetermined deterioration level and the importance level is higher than a predetermined importance level, and to temporarily suspend operation of the equipment if the deterioration level is higher than a predetermined deterioration level.

[0115] When the operation support information analysis unit 1121 determines that the operation of the equipment is to be suspended, it causes the display unit 13 to display a suspension instruction notice indicating that the operation of the equipment is to be suspended as an operation method of the equipment.

[0116] If the operation support information analysis unit 1121 determines to continue operation of the equipment, it extracts an equipment operation method for continuing operation of the equipment under the conditions of the acquired deterioration type and deterioration level from the equipment operation history stored in the operation management storage unit 21 of the operation management support database device 20. The operation support information analysis unit 1121 extracts an equipment operation method having conditions similar to the acquired deterioration type, deterioration level, and importance level from the equipment operation history stored in the operation management storage unit 21. The operation support information analysis unit 1121 transmits the extracted information on the equipment operation method to the simulation unit 1122 together with the information on the deterioration type and deterioration level transmitted from the maintenance management support device 12. In addition, the operation support information analysis unit 1121 displays the extracted information on the equipment operation method on an equipment operation history confirmation screen (described later) of the display unit 13.

[0117] The simulation unit 1122 acquires the information on the type and degree of deterioration transmitted from the operation support information analysis unit 1121, and the information on the operation method of the equipment extracted by the operation support information analysis unit 1121. Based on the acquired information on the type and degree of deterioration, the simulation unit 1122 simulates the operation method of the equipment for continuing operation in the situation of the acquired type and degree of deterioration, using the water level, water quality, and energy as KPIs.

[0118] The simulation unit 1122 simulates an equipment operation method for continuing operation of the equipment under the conditions of the acquired deterioration type and deterioration level, in which the operating state of the deteriorated equipment satisfies a predetermined operating state. The simulation unit 1122 also simulates an equipment operation method for satisfying predetermined target conditions for water level, water quality, and energy. The predetermined water level, water quality, and energy are each a plurality of evaluation indices for evaluating the operating state of the equipment. The predetermined target conditions for water level, water quality, and energy can be said to be predetermined operating states of the deteriorated equipment. The simulation unit 1122 also simulates an equipment operation method for satisfying a predetermined balance between the evaluation indices of water level, water quality, and energy.

[0119] That is, the simulation unit 1122 predicts changes in evaluation indexes such as water level, water quality, and energy, and simulates an operation method for the water treatment facility that satisfies predetermined target conditions for water level, water quality, and energy and achieves a good balance among the water level, water quality, and energy.The simulation unit 1122 also simulates the operation method for the facility extracted by the operation support information analysis unit 1121 to determine whether the predetermined target conditions for water level, water quality, and energy are met, and the balance among the water level, water quality, and energy.

[0120] The simulation unit 1122 determines, from among the simulated equipment operation methods, including the equipment operation method extracted by the operation support information analysis unit 1121, an equipment operation method that satisfies predetermined target conditions for water level, water quality, and energy and that satisfies a predetermined balance between water level, water quality, and energy, as the equipment operation method for continuing operation of the equipment in the occurrence status of the acquired deterioration type and deterioration level.In this way, the simulation unit 1122 simulates a more preferable equipment operation method for continuing operation of deteriorated equipment, based on the deterioration type, deterioration level, and predetermined importance of the equipment in the water treatment plant.

[0121] The water level is the water level of the primary sedimentation tank 71, the biological reactor 73, or the final sedimentation tank 76. The water quality is the water quality of the biological reactor 73 or the final sedimentation tank 76. The energy is the electricity used to operate the equipment. The target conditions for the water level, water quality, and energy may be determined in advance and stored in the simulation unit 1122, or may be input to the simulation unit 1122 from outside the simulation unit 1122 as needed. Then, the process proceeds to step S160.

[0122] In step S160, the determined equipment operation method is output. Specifically, the simulation unit 1122 outputs information about the determined equipment operation method to the display unit 13, and displays the determined equipment operation method on the display unit 13 to present to the worker. This allows the worker to consider how to respond when an abnormality occurs in the equipment based on the equipment operation method of the simulation results presented by the operation management support device 11, and allows the worker to quickly and easily respond when an abnormality occurs in the equipment.

[0123] In step S170, the operation support information analysis unit 1111 transmits and stores the current normal operation method of the equipment, i.e., information on the current normal operation of the equipment, as an equipment operation history to the operation management storage unit 21 of the operation management support database device 20. Here, the operation support information analysis unit 1111 associates the current normal operation information of the equipment with other information such as information on the type and degree of deterioration, information on the current time, information on the current weather, and information on the current processing volume, and stores the information in the operation management storage unit 21 of the operation management support database device 20. In this way, the current normal operation method of the equipment is stored as an equipment operation history in the operation management storage unit 21 of the operation management support database device 20, making it possible to accumulate know-how on equipment operation methods.

[0124] Furthermore, the operation support information analysis unit 1111 displays on the display unit 13 the equipment operation history that corresponds to the current equipment operating conditions among the equipment operation history stored in the operation management storage unit 21 of the operation management support database device 20. This allows the operator to continue appropriate operation of the equipment based on the appropriate equipment operation history under normal conditions that is displayed on the display unit 13.

[0125] FIG. 12 is a diagram showing an example of a maintenance management screen displayed on the display unit according to the first embodiment. In steps S130 to S140 described above, for example, the maintenance management screen shown in FIG. 12 is displayed on the display unit 13. In the graph on the maintenance management screen shown in FIG. 12, the horizontal axis represents time and the vertical axis represents the degree of deterioration. The graph on the maintenance management screen shown in FIG. 12 shows the progression of the degree of deterioration. The maintenance management screen shown in FIG. 12 displays that the operating states of the first pump and the second pump are in a rated operating state, and that the operating states of the third pump and the fourth pump are in a suspended state. It also displays that the states of the first pump, the third pump, and the fourth pump are determined to be normal, and that the state of the second pump is determined to be an abnormal state with a deterioration level of 3.

[0126] Fig. 13 is a diagram showing an example of an apparatus operation history confirmation screen displayed on the display unit according to the first embodiment. In step S150 described above, for example, the apparatus operation history confirmation screen shown in Fig. 13 is displayed on the display unit 13. The apparatus operation history confirmation screen shown in Fig. 13 displays an operation method of the equipment extracted by the operation support information analysis unit 1121 from the apparatus operation history stored in the operation management storage unit 21. The apparatus operation history confirmation screen shown in Fig. 13 displays an operation method of the equipment when the deterioration type is a bearing abnormality and the second pump, which has a high importance level, has a deterioration level of 3.

[0127] In the graphs for the first pump and the third pump on the device operation history confirmation screen shown in Fig. 13, the horizontal axis represents time, and the vertical axis represents whether the pump is on or off. The graphs for the first pump and the third pump on the device operation history confirmation screen shown in Fig. 13 represent the operating status of the pumps. In the graph for the water level on the device operation history confirmation screen shown in Fig. 13, the horizontal axis represents time, and the vertical axis represents water level. In the graph for the water quality on the device operation history confirmation screen shown in Fig. 13, the horizontal axis represents time, and the vertical axis represents water quality.

[0128] FIG. 14 is a diagram illustrating an example of a simulation screen displayed on the display unit according to the first embodiment. In step S150 described above, for example, the simulation screen illustrated in FIG. 14 is displayed on the display unit 13. On the simulation screen illustrated in FIG. 14, the equipment operation method simulated by the simulation unit 1122 is displayed on the display unit 13. FIG. 14 illustrates a portion of the equipment operation method simulated by the simulation unit 1122. In the graphs of the first pump and the third pump on the simulation screen illustrated in FIG. 14, the equipment operation method illustrated on the equipment operation history confirmation screen illustrated in FIG. 13 is indicated by a thin line. In the graph of the third pump on the simulation screen illustrated in FIG. 14, the equipment operation method changed by the equipment operation method simulated by the simulation unit 1122, relative to the equipment operation method illustrated on the equipment operation history confirmation screen illustrated in FIG. 13, is indicated by a medium-thick line.

[0129] In the graphs of water level and water quality on the simulation screen shown in Fig. 14, the transitions of the water level and water quality, which are KPIs corresponding to the equipment operation method shown on the equipment operation history confirmation screen shown in Fig. 13, are shown by dashed lines. Also, in the graphs of water level and water quality on the simulation screen shown in Fig. 14, the transitions of the water level and water quality, which are KPIs corresponding to the equipment operation method simulated by the simulation unit 1122, are shown by solid lines.

[0130] Furthermore, on the simulation screen shown in Fig. 14, information on the balance of KPIs corresponding to the equipment operation methods shown on the equipment operation history confirmation screen shown in Fig. 13 is shown by thin lines. Furthermore, on the simulation screen shown in Fig. 14, information on the balance of KPIs corresponding to the equipment operation methods simulated by the simulation unit 1122 is shown by medium-thick lines.

[0131] 14, the equipment operation method simulated by the simulation unit 1122 has improved all of the KPIs compared to the equipment operation method extracted from the equipment operation history stored in the operation management storage unit 21. In other words, the equipment operation method simulated by the simulation unit 1122 is more preferable as an equipment operation method for continuing equipment operation under the current equipment deterioration type and deterioration level conditions than the equipment operation method extracted from the equipment operation history stored in the operation management storage unit 21.

[0132] For example, an operator monitors the status of each pump on the maintenance management screen shown in FIG. 12, and when he or she finds that the level of deterioration has increased, he or she can check the type of pump and the level of deterioration at that time. Furthermore, by checking the equipment operation history confirmation screen shown in FIG. 13, the operator can manually determine whether to operate the third pump because the second pump is abnormal, and how to operate the third pump. In response to this determination, the simulation unit 1122 simulates what operation method is appropriate to achieve more favorable conditions for the KPIs of water level, water quality, and energy, and the equipment operation method resulting from the simulation is displayed on the display unit 13. The operator can determine the equipment operation method based on the equipment operation method resulting from the simulation displayed on the display unit 13 shown in FIG. 14.

[0133] Therefore, the simulation unit 1122 can simulate an equipment operation method for continuing operation of the equipment in the situation of the acquired deterioration type and deterioration level, using the water level, water quality, and energy as KPIs, based on the acquired information on the deterioration type and deterioration level. Furthermore, the simulation unit 1122 can simulate an equipment operation method for continuing operation of the equipment in the situation of the acquired deterioration type and deterioration level, using the water level, water quality, and energy as KPIs, based on the equipment operation method determined by the worker, which is information determined by the worker based on the display of the maintenance management screen shown in FIG. 12 . The information determined by the worker can be input to the simulation unit 1122 using, for example, input means provided in the terminal 40 or the monitoring system. Then, the simulation unit 1122 simulates an equipment operation method for continuing operation of the equipment in the situation of the acquired deterioration type and deterioration level, using the water level, water quality, and energy as KPIs, based on the equipment operation method determined by the worker that has been input to the simulation unit 1122.

[0134] By carrying out the above processing, the management system 10 can provide support for the maintenance management of the water treatment plant and the operation management of the equipment of the water treatment plant in a seamless manner.

[0135] A modified example of the management process for water treatment equipment in the management system according to the first embodiment will be described. As described above, the operator can determine an equipment operation method based on the equipment operation method of the simulation results displayed on the display unit 13 shown in FIG. 14. The operator operates the equipment of the water treatment plant using the equipment operation method determined based on the equipment operation method of the simulation results. Here, the operator operates the equipment of the water treatment plant using an operation device (not shown) provided in the management system 10 in accordance with the determined equipment operation method. The operation device is a device by which the operator operates the equipment of the water treatment plant, i.e., a device by which the operator controls the operation of the equipment of the water treatment plant. The operation device may have an automatic operation function for automatically operating the equipment of the water treatment plant. The operation device may be provided independently of the management system 10.

[0136] The operating device is connected to controllers such as the mechanical equipment controller 60 and the water treatment equipment controller 70. In other words, the operating device can exchange information with controllers such as the mechanical equipment controller 60 and the water treatment equipment controller 70. Communication between the operating device and each controller may be wireless or wired.

[0137] The operating device controls the operation of the mechanical equipment by sending control commands to the mechanical equipment controller 60 so that the mechanical equipment controller 60 controls the operation of the equipment in the equipment facility 63. The operating device also controls the operation of the water treatment facility by sending control commands to the water treatment facility controller 70 so that the water treatment facility controller 70 controls the operation of the equipment in the water treatment facility.

[0138] The operation device is also connected to the operation management support device 11 and the operation management support database device 20. That is, the operation device can exchange information with the operation management support device 11 and the operation management support database device 20. Communication between the operation device and the operation management support device 11 and the operation management support database device 20 may be wireless or wired communication.

[0139] As described above, when the operation support information analysis unit 1111 of the normal state response support unit 111 of the operation management support device 11 determines that there is no abnormality in the equipment based on the information on the deterioration type and deterioration level transmitted from the maintenance management support device 12, it transmits and stores the current normal state equipment operation method, i.e., information on the current normal state equipment operation, as an equipment operation history to the operation management storage unit 21 of the operation management support database device 20. The operation support information analysis unit 1111 of the normal state response support unit 111 acquires the current normal state equipment operation information from the operation device, and transmits the acquired equipment operation information as an equipment operation history to the operation management storage unit 21 of the operation management support database device 20.

[0140] Meanwhile, the operation support information analysis unit 1121 of the abnormality response support unit 112 of the operation management support device 11 transmits and stores, as an equipment operation history, the equipment operation method performed from the operation device in the event of an abnormality after the equipment operation method of the simulation results was displayed on the display unit 13, i.e., information on the equipment operation in the event of an abnormality, to the operation management storage unit 21 of the operation management support database device 20. The operation support information analysis unit 1121 of the abnormality response support unit 112 acquires, from the operation device, information on the equipment operation in the event of an abnormality that was performed from the operation device after the equipment operation method of the simulation results was displayed on the display unit 13, and transmits the acquired information on the equipment operation as an equipment operation history to the operation management storage unit 21 of the operation management support database device 20.

[0141] Furthermore, the operation support information analysis unit 1121 of the abnormality response support unit 112 can link judgment information, which is information about what judgment the worker made based on the simulation results when deciding on an operation method for the equipment in the event of an abnormality, to information about the operation method for the equipment, and store the information in the operation management storage unit 21 of the operation management support database device 20 in the equipment operation history. The worker can input the judgment information to the operation support information analysis unit 1121 of the abnormality response support unit 112, for example, using input means provided in the terminal 40 or the monitoring system.

[0142] The above-mentioned management system 10 realizes a management system that includes an analysis unit that determines the type and degree of deterioration occurring in the equipment from the results of a deterioration diagnosis using status information that indicates the status of the equipment in the water treatment plant, and a simulation unit that simulates an operation method for the equipment to continue operating the water treatment plant based on the type and degree of deterioration and the predetermined importance of the equipment in the water treatment plant.

[0143] The management system 10 having such a configuration can automatically determine the type of deterioration occurring in the equipment and the degree of deterioration based on sensor information, and automatically detect whether or not an abnormality has occurred in the equipment. This makes it possible for the management system 10 to propose an operation method for equipment based on remote monitoring, i.e., an operation method for equipment based on remote monitoring, and eliminates the need for workers to patrol each piece of equipment in the water treatment plant to check for the presence or absence of an abnormality in the equipment, thereby reducing the burden on workers in maintenance management work and realizing labor savings in maintenance management work.

[0144] In addition, when the management system 10 detects whether or not an abnormality has occurred in the equipment, it can automatically suggest an operating method appropriate to the condition of the equipment, thereby realizing safe, stable, and appropriate operation management of the equipment without relying on manuals for responding to equipment abnormalities, etc.

[0145] Furthermore, the management system 10 can provide support for the maintenance management of the water treatment plant and the operation management of the equipment of the water treatment plant in a seamless manner using the same system, thereby improving the operability of the management equipment for operators in supporting the maintenance management and operation management of the water treatment plant.

[0146] The management system 10 can also propose equipment operation methods based on the type, severity, and importance of the equipment, based on past equipment operation history and simulation results. For example, the management system can change the equipment operation method depending on the type of deterioration, such as continuing operation if there is a minor bearing abnormality and suspending operation if there is an electrical short circuit abnormality that indicates significant deterioration. The management system can also change the equipment operation method depending on the severity of the deterioration, such as continuing operation if the severity of the deterioration is low and suspending operation if the severity of the deterioration is high. The management system can also change the operation method based on the balance between the severity and severity of the deterioration, such as continuing operation if the severity of the deterioration is low and immediately suspending operation if the severity of the deterioration is high, even if the severity of the deterioration is low. This allows the management system 10 to present appropriate equipment operation methods to operators based on the status of the equipment and the importance of the equipment in the water treatment plant. The management system 10 can not only determine whether the equipment is normal or abnormal, but also determine whether the abnormality is severe, moderate, or mild based on the severity of the deterioration.

[0147] Although the above describes the case where the diagnostic device is installed in the mechanical equipment or the water treatment equipment, the location of the diagnostic device is not limited. The diagnostic device may be installed in the equipment controller such as the mechanical equipment controller 60 or the water treatment equipment controller 70, in the terminal 40, in the server 50, or in another device not shown.

[0148] Although the above describes a case where sensor information is transmitted to the management system 10 via equipment controllers such as the mechanical equipment controller 60 and the water treatment equipment controller 70, the transmission path of the sensor information is not limited. The sensor information may be transmitted directly to the management system 10 without going through a controller, may be transmitted to the management system 10 via the terminal 40, or may be provided in another device not shown.

[0149] In addition, although the above describes a case where the maintenance management support device 12 and the operation management support device 11 are located in the same place, the maintenance management support device 12 and the operation management support device 11 may be located in different places. For example, one of the functions of the maintenance management support device 12 and the operation management support device 11 may be provided in the server 50, or may be provided in another device not shown.

[0150] In the above description, the sensor information acquisition unit 121, the diagnosis result information acquisition unit 122, and the analysis unit 123 are provided in the maintenance management support device 12, but these components may be provided in different locations. For example, the sensor information acquisition unit 121 and the diagnosis result information acquisition unit 122 may be provided in the maintenance management support device 12, and the analysis unit 123 may be provided in the server 50 or another device not shown. When the analysis unit 123 is provided in the server 50 or another device not shown, the analysis unit 123 can be accessed from other water treatment plants, and the analysis unit 123 can be shared among a plurality of water treatment plants.

[0151] In the above description, the degradation diagnosis analysis unit 1231 and the degradation degree calculation unit 1232 are provided in the analysis unit 123, but the degradation diagnosis analysis unit 1231 and the degradation degree calculation unit 1232 may be provided in different locations. For example, one of the degradation diagnosis analysis unit 1231 and the degradation degree calculation unit 1232 may be provided in the analysis unit 123, and the other may be provided in the server 50 or another device not shown.

[0152] In addition, although the above describes a case where the driving support information analysis unit 1121 and the simulation unit 1122 are provided in the abnormality response support unit 112 of the driving management support device 11, the driving support information analysis unit 1121 and the simulation unit 1122 may be provided in different locations. For example, one of the driving support information analysis unit 1121 and the simulation unit 1122 may be provided in the abnormality response support unit 112, and the other may be provided in the server 50 or another device not shown.

[0153] In addition, although the above describes a case where the normal state response support unit 111 and the abnormal state response support unit 112 are provided in the operation management support device 11, the normal state response support unit 111 and the abnormal state response support unit 112 may be provided in different locations. For example, one of the normal state response support unit 111 and the abnormal state response support unit 112 may be provided in the operation management support device 11, and the other may be provided in the server 50 or another device not shown.

[0154] In the above, the case has been described in which equipment diagnostic device 62 is provided separately from analysis unit 123, and analysis unit 123 performs degradation diagnosis on the water treatment equipment, but degradation diagnosis of all equipment may be performed by analysis unit 123. Alternatively, a degradation diagnosis device that performs degradation diagnosis on each piece of equipment in the water treatment equipment may be provided, and analysis unit 123 may also acquire diagnosis result information for the water treatment equipment from that degradation diagnosis device. Degradation diagnosis of each piece of equipment may be performed by analysis unit 123, respectively, or by a separate diagnostic device, and the device that performs degradation diagnosis is not limited to the example described above.

[0155] As described above, the management system 10 according to the first embodiment has the effect of reducing the burden of maintenance management work on the workers of the water treatment plant.
