  (Step S201) First, the CPU 25 acquires collected data, that is, model identification information and state history information (including operation history information and measured value history information) from the terminal device 1.

  (Step S202) Next, the CPU 25 performs data analysis on the state history information. For example, the CPU 25 compares the state history information of the pump device P with the normal state history information of the same model as the monitored device stored in the storage device 3 and detects a failure in the state history information of the pump device P. It is determined whether there is a specific state change before. When there is a specific state change before the occurrence of the failure, the CPU 25 may transmit information on the specific state change and / or information on the failure event to the terminal device 1 before the occurrence of the failure, for example. Then, the terminal device 1 may receive and display information on a specific state change and / or information on a failure event before a failure occurs. This allows the local service personnel to recognize the specific state change and / or the failure predicted in the future before the occurrence of the failure, thereby assisting the local service personnel in making the determination.

  Here, a method of determining a specific state change before a failure occurs will be described. The terminal device 1 may transmit the state history information before the failure of the monitored device for each failure event. Then, the information processing device 2 causes the storage device 3 to accumulate state history information of the monitored device before the occurrence of the failure for each failure event. As a result, the state history information of the monitored device before the occurrence of the failure is accumulated in the storage device 3 for each failure event.

The CPU 25 of the information processing device 2 statistically processes the state history information before the occurrence of the failure for each failure event, and determines a unique state change before the occurrence of the failure. Specifically, for example, the CPU 25
For a plurality of state history information before the occurrence of a failure, a branch point at which a parameter (for example, a motor temperature rise rate) changes rapidly is extracted, and parameters (for example, a motor temperature rise rate) before and after the branch point are compared. If there is a difference between the values that is equal to or greater than a predetermined ratio (or if there is a statistically significant difference), the state change (for example, an increase in the motor temperature increase rate) is performed before a failure occurs. To decide. This makes it possible to predict the occurrence of a future failure event (event). By accumulating the state history information of the monitored device before the occurrence of the failure in the storage device 3 for each failure event as needed, it is possible to improve the detection accuracy of a proper correct state change before the occurrence of the failure.

In addition, the storage device 3 stores, in association with the past failure, model identification information, a state change peculiar to the occurrence of the failure, repair work contents, parts to be replaced, and the like. Further, a failed component may be further stored in association with the failed component. In this case, the CPU 25 refers to, for example, the storage device 3, and the CPU 25 performs, for example, the repair work content associated with the specific state change and the model identification information for identifying the model of the pump device P before the occurrence of the failure. And / or extracts components to be replaced from the storage device 3 and executes control for transmitting the repair work content and / or information on the components to be replaced to the terminal device 1.
This allows the local service staff to provide the information necessary for providing the user of the pump device P with optimum maintenance work, so that a repair plan can be made before the pump device P fails. Can be.

  (Step S203) Then, the CPU 25 determines whether or not the operating state of the pump is normal based on the result of the data analysis.

For example, in the normal operation history information stored in the storage device 3, as shown in FIG. 8A, it is assumed that one pump operation has been continued for about four hours. On the other hand, in the latest operation history information collected, it is assumed that the start and stop of the pump are repeated in a short time as shown in FIG. Here, the normal operation history information is stored in the storage device 3 for each model by the process of step S204 described later.
In this case, the CPU 25 determines that the operating state of the pump 102 is not normal (that is, abnormal) when the duration of the pump operation shorter than the threshold time is repeated a predetermined threshold number of times. Here, the threshold time may be determined based on a past average duration of the pump operation. For example, the threshold time may be half the duration of the past average pump operation.

Further, for example, in the normal operation history information stored in the storage device 3, as shown in FIG. 9A, it is assumed that the number of pump activations per hour is about 5 to 8 times. On the other hand, in the collected latest operation history information, as shown in FIG. 9B, it is assumed that the number of times of activation of the pump 102 per hour has sharply increased at time t1.
In this case, for example, the CPU 25 determines the maximum value of the number of pump starts per hour in the normal operation history information as the threshold Th, and the number of pump starts per hour in the latest operation history information exceeds the threshold Th. In this case, it is determined that the operation state of the pump device P is not normal (that is, abnormal).

  (Step S204) If it is determined in step S203 that the operating state of the pump is normal, the CPU 25 uses the acquired collected data (that is, state history information) as normal state history information (also referred to as normal state data). It is stored in the storage device 3.

  (Step S205) Next, the CPU 25 performs control for transmitting a determination result (here, a determination result indicating that the pump is normal) to the terminal device 1. Thereafter, the process proceeds to step S215 and step S216.

  (Step S206) When it is determined in step S203 that the operating state of the pump is not normal, it is determined whether or not there is precedent information on the abnormality.

  (Step S207) When it is determined in step S206 that there is precedent information on the abnormality, the CPU 25 extracts the contents of the abnormality, the repair work plan, the work instruction information, and the component replacement cost accumulation from the storage device 3.

  Here, for an abnormality having a precedent, the storage device 3 stores in the storage device 3 the details of the abnormality of the precedent, the determination condition, the repair work plan corresponding to the details of the abnormality of the precedent, the work instruction information corresponding to the details of the abnormality of the precedent, and the abnormality of the precedent. The component replacement cost accumulation corresponding to the content is stored in association with the content.

  For example, in the case of the abnormality shown in FIG. 8B, when the duration of the pump operation shorter than the threshold time is repeated a predetermined threshold number of times, a water leak in the pump pipe portion is assumed. If there is a precedent for this situation, the storage device 3 previously repeats the content of the abnormality “water leakage in the pump piping section” and the duration of the pump operation shorter than the threshold time a predetermined threshold number of times. Judgment condition "repair work plan corresponding to" pump piping leak ", work instruction information corresponding to" pump piping leak ", parts replacement corresponding to" pump piping leak " Cost estimates are stored in association with each other.

  For example, in the case shown in FIG. 8B, the duration of the pump operation shorter than the threshold time is repeated a predetermined threshold number of times, and therefore, in step S209, the CPU 25 The record of the precedent information corresponding to the condition that “the duration is repeated a predetermined threshold number of times” is searched in the storage device 3, and if there is a record of the precedent information (YES in step S206), the record is included in this record. The abnormal contents, the repair work plan, the work instruction information, and the component replacement cost estimation are extracted from the storage device 3.

  For example, in the case of the abnormality shown in FIG. 9 (B), the maximum value of the number of pump startups per hour in the normal operation history information is set as the threshold Th, and when the threshold Th is exceeded, the water in the pump pipe section is changed. Leakage is assumed. If there is a precedent for this situation, the storage device 3 stores in advance the content of the abnormality "water leakage in the pump piping section" and the maximum number of pump starts per hour in the normal operation history information. Condition, "Repair work plan corresponding to" Pump piping leak ", Work instruction information corresponding to" Pump piping leak ", Parts corresponding to" Pump piping leak " The exchange cost accumulation is stored in association with the exchange cost accumulation.

  For example, in the case of the abnormality shown in FIG. 9B, the duration of the pump operation shorter than the threshold time is repeated a predetermined threshold number of times. The record of the precedent information corresponding to the condition that “the duration is repeated a predetermined threshold number of times” is searched in the storage device 3, and if there is a record of the precedent information (YES in step S206), the record is included in this record. The abnormal contents, the repair work plan, the work instruction information, and the component replacement cost estimation are extracted from the storage device 3.

  (Step S208) Next, the CPU 25 performs control for transmitting the determination result to the terminal device 1. Here, the determination result includes, in addition to the content of the determination that the pump is abnormal, the content of the abnormality, the repair work plan, the work instruction information, and the component replacement cost estimation. Thereafter, the process proceeds to step S215 and step S216.

  (Step S209) When it is determined in step S209 that there is no precedent information of the abnormality, the CPU 25 determines whether or not a takeover investigation is necessary according to a predetermined rule, and performs a process of summarizing the failure assumption contents according to a predetermined rule. Execute.

After step S209, the CPU 25 executes step S210 and steps S211 to S214 in parallel.
(Step S210) The CPU 25 performs control for transmitting the determination result to the terminal device 1. Here, the determination result includes the content of the determination that the pump is abnormal. Thereafter, the process proceeds to step S215.

  (Step S211) The CPU 25 executes processing for transmitting the fact that an abnormality has occurred in the manufacturer of the pump device 1 and transmitting detailed information thereof.

  (Step S212) The CPU 25 requests the terminal device 1 for a failed component (for example, a bearing). In response to this request, the terminal device 1 displays information that prompts the service technician to check for a failed component, and also displays information that prompts the user to input the failed component. Then, when a faulty component is input from the service staff, the terminal device 1 transmits faulty component identification information for identifying the faulty component to the information processing device 2. The CPU 25 acquires the failed component in this manner. Here, the storage device 3 stores, for each failed component, failed component identification information for identifying the failed component and work items for the failed component in association with each other. The CPU 25 refers to the storage device 3 and acquires a work item corresponding to the acquired failed component.

  (Step S213) The CPU 25 performs a failure analysis. For example, an example where a bearing failure occurs will be described. FIG. 10A shows L1 indicating a time-series change in the pump operation state in a normal state and L2 indicating a time-series change in the motor temperature. On the other hand, FIG. 10B shows L3 indicating a time-series change in the pump operation state immediately before the occurrence of the bearing failure and L4 indicating a time-series change in the motor temperature. As shown in FIG. 10B, a large increase in the motor temperature increase rate is observed immediately before the occurrence of a failure as compared with the normal state. However, the increased temperature is equal to or lower than the motor temperature upper limit and is not abnormal in motor design. That is, by analyzing the motor temperature rise rate, it is possible to predict a bearing failure.

  In the example of FIG. 10, in step S213, the CPU 25 determines, for each of a plurality of predetermined state changes including the motor temperature increase rate, the normal state history information of the same model and the abnormal state history information generated this time. Compare with At this time, when the state change obtained from the abnormal state history information that has occurred this time does not fall within the normal range of the state change set from the normal state history information, by using this state change, Abnormality or failure can be predicted. Therefore, in this case, the CPU 25 sets the state change as a determination item.

  Next, the CPU 25 extracts state history information in which the extracted state change is observed from a plurality of state history information of the same model that has failed in the past. For example, in the case of the example of FIG. 10B, the CPU 25 calculates the motor temperature rise within a range of less than the motor temperature upper limit value as shown in FIG. The state history information whose rate is higher than usual is extracted. Then, using the extracted state history information, the CPU 25 determines a determination condition for determining the state history information in which the motor temperature rise rate is higher than normal within a range less than the motor temperature upper limit value. Specifically, for example, if the motor temperature rise rate of at least 20% of the extracted state history information is higher than that of the normal state, the CPU 25 increases the motor temperature rise rate by 20% from the normal state. The above increase may be determined as the determination condition.

As described above, the CPU 25 extracts state history information in which an extracted state change is observed from a plurality of state history information of the same model that has failed in the past, and determines a determination condition using the extracted state history information. .
As a result, it is possible to newly discover a causal relationship between the failure and the extracted state change, which the business operator could not predict in advance. For this reason, the accuracy of failure prediction can be improved, and the service personnel of the business can improve the validity of the schedule for maintenance work. And / or suggest a budget.

  (Step S214) The CPU 25 sets work items (recommended or guided items) from the failed parts acquired in step S212. For example, when the failed part is “bearing”, the CPU 25 refers to the storage device 3 and sets “replacement of bearing” as a work item (recommended or guided item). Then, the CPU 25 performs control for transmitting information including the determination item, the determination condition, and the set work item set in step S213 to the terminal device 1. Then, the terminal device 1 adds these pieces of information to the table T1 of FIG. 5 stored in the storage unit 11. Thus, the terminal device 1 can display the additionally written work item when the additionally written determination item corresponds to the additionally written determination condition.

  As a result, a causal relationship between a newly discovered failure and a state change that could not be predicted in advance by the business operator can be added as a determination item of the terminal device 1 at any time. If there is a similar tendency of the state change thereafter, the terminal device 1 can display, as a work item, guidance for replacement of a component that may fail in the future, and Can propose replacement of parts before a failure occurs.

  Further, for example, an example in which a disconnection failure of the temperature measuring device (temperature sensor) 106 occurs will be described. FIG. 11A shows L5 indicating a time-series change in the pump operation state in a normal state and L6 indicating a time-series change in the motor temperature. On the other hand, FIG. 11B shows L7 indicating a time-series change in the pump operation state immediately before the failure of the temperature measuring device (temperature sensor) 106 and L8 indicating a time-series change in the motor temperature. . As shown in FIG. 11B, the motor temperature rise rate is significantly reduced immediately before the occurrence of a failure as compared with the normal state. However, the increased temperature is equal to or lower than the motor temperature upper limit and is not abnormal in motor design. That is, if the motor temperature rise rate is analyzed, it is possible to predict the failure of the temperature measuring device (temperature sensor) 106. In this case, the CPU 25 performs control for adding a record for this determination to the table T1 of the terminal device 1.

  (Step S215) The CPU 25 stores the determination result in the storage device 3.

In this way, the storage device 3 stores, for each failed component, the failed component identification information for identifying the failed component and the work item for the failed component in association with each other. The terminal device 1 receives an input of a failed component of the failed monitored device from the operator, and transmits to the information processing device 2 failed component identification information for identifying the received failed component.
The CPU 25 refers to the storage device 3 and acquires a work item corresponding to the received failed component identification information. The CPU 25 compares the state history information before the failure of the monitored device with the normal state history information stored in the storage device 3 and having the same model as that of the failed monitored device, and extracts a state change. The CPU 25 determines a determination condition for determining whether or not the extracted state change is normal. Then, the CPU 25 performs control for transmitting the state change, the determination condition, and the work item to the terminal device 1.

The terminal device 1 receives the state change, the determination condition, and the work item, stores the state change, the determination condition, and the work item in association with each other, and, when receiving certain state history information, stores the state history information. It is determined whether the state change satisfies the corresponding determination condition. If the determination condition is satisfied, a work item corresponding to the determination condition corresponding to the set of the state change and the determination condition is displayed.
With this, when the state change satisfies the determination condition, the work item suitable for the failed portion corresponding to the state change can be displayed, so that a repair plan can be made before the monitored device fails. it can.

  In addition, by utilizing the information processing system S according to the present embodiment, it is possible to smooth the state diagnosis, which has been conventionally entrusted to the human skill and know-how of the inspector at the time of the periodic inspection, to a certain level. Further, it is possible to correct the instability of the post-repair life caused by the difference in the judgment level due to the difference in the work staff. In addition, since unnecessary parts are not replaced, unnecessary inspections and unnecessary repairs are not performed, costs can be reduced, and waste generated in the repair work can be reduced. We can expect improvement. Furthermore, even in a state where the operation of the pump device P is maintained, the status report presented to the user at the time of inspection can be provided with numerical support.

  Note that the precedent information may be updated after the failure analysis in step S213. Specifically, for example, the CPU 25 may additionally write a set of the abnormality content acquired in step S212 and the set determination condition to the storage device 3 as a record of new precedent information. In addition, the repair work plan, the work instruction sheet information, and the component replacement cost estimation may be added to this record by the operator of the information processing apparatus 2. In this way, when there is no precedent information, the precedent information is added, and when there is a similar abnormality thereafter, the renovation work plan, the work instruction sheet, The information, the component replacement cost estimation, and the like can be displayed on the terminal device 1. Therefore, when there is a similar abnormality thereafter, the service technician refers to the information displayed on the terminal device 1 and immediately obtains an appropriate repair work plan, work contents, parts replacement costs, and the like at the site. Can be suggested to users.

  Further, the CPU 25 extracts, for the data immediately before the failure, how long after a state change that satisfies the determination condition is found, how long after the failure, the new record of the remaining life period is newly added to the corresponding record of the precedent information. Items may be provided and added. After that, when the same determination condition is satisfied thereafter, the CPU 25 may extract from the precedent information how long the failure will take, and execute control for transmitting the failure to the terminal device 1. . Then, the terminal device 1 may display information about how long the corresponding component will be out of order. Thereby, the service person using the terminal device 1 can lengthen or shorten the interval of the maintenance and inspection according to this information. Can be adjusted. Further, it is possible to determine an individual inspection standard for each device to be inspected, such as extending the initial periodic inspection execution interval or changing the frequency of the periodic inspection. For this reason, the service staff of the business can propose an inspection program suitable for the state of the equipment without excessive inspection and equipment investment, which is the case when a conventional remote monitoring device is installed.

  In the present embodiment, the communication between the pump device P and the terminal device 1 is a wireless LAN, but is not limited thereto, and may be another short-range wireless communication. Further, the information processing device 2 and the storage device 3 are connected by the local network LN, but are not limited thereto, and may be a global network. Further, the terminal device 1 may have the function of the information processing device 2 or may have the function of the information processing device 2 and the storage device 3.
