[0009] Hereinafter, embodiments of the present invention (referred to as "the present embodiment") will be described with reference to the drawings. The present embodiment is an example of managing water quality in a water supply-related facility (not shown). The water supply management facility is a concept including a water purification plant and a sewage treatment plant. However, the present invention is also applicable to general plants (not shown) other than water supply management facilities.

[0010] FIG. 1 is a diagram showing the configuration of an action procedure information display system in the present embodiment. The action procedure information display system 100 includes a water quality data collection server 1, a water quality data storage unit 2, an event information storage unit 3, a water quality monitoring control server 4, a document information storage unit 5, a document viewing information storage unit 6, a driver information terminal 7, an action procedure information storage unit 8, a surveillance camera 9, and an action procedure information management server (action procedure information management device) 10. These are connected by a network 11.

[0011] In plants other than water management facilities, the water quality data collection server 1 becomes a "sensor data collection server 1" that collects arbitrary sensor values of the plant, and the water quality monitoring control server 4 becomes a "plant monitoring control server 4" that monitors and controls arbitrary devices constituting the plant. The action procedure information management device 10, the sensor data collection server 1, the plant monitoring control server 4, and the driver information terminal 7 constitute an action procedure information management system 100.

[0012] The water quality data collection server 1 uses sensors installed at specific locations such as intake wells and receiving wells to collect data on specific indicators related to water, such as turbidity and pH, as water quality data, attaches a timestamp (date and time), and transmits it to the water quality data storage unit 2. The water quality data collection server 1 includes a water quality data measurement unit 1a and a water quality data transmission unit 1b. The water quality data measurement unit 1a collects data on specific indicators as water quality data using sensors.

The action procedure information search unit 10e includes a similar date and time extraction unit 10q, an event extraction unit 10r, an event screening unit 10s, and an action procedure information extraction unit 10t. The similar date and time extraction unit 10q receives water quality data from the water quality / event information receiving unit 10a. The similar date and time extraction unit 10q calculates the similarity between a specific index such as turbidity at a reference date and time such as the current time and the specific index at each past time according to the similarity calculation formula selected by the similarity calculation formula type receiving unit 10c for the received water quality data. The similar date and time extraction unit 10q extracts several past dates and times in descending order of the calculated similarity. As an example of the similarity calculation formula, a calculation formula for the divergence degree, which is the reciprocal of the similarity, is shown in Equation (1).

[0042] [Equation 1] TIFF0007698591000001.tif16145

[0043] "dtw" on the left side of Equation (1) is the divergence degree, which is the reciprocal of the similarity. "turb(t)" on the right side is the value of the specific index at time t. The specific index is selected from among turbidity, pH, etc. The specific index is also called the "target variable" in the sense that it is included as a variable in the similarity calculation formula. "t b " on the right side is the reference date and time. "t s " on the right side is the past date and time. "ΔT" on the right side is the sampling period. "i" on the right side is a coefficient (i = 0, 1, 2, ···, n) multiplied by the sampling period.

[0044] The similar date / time extraction unit 10q randomly acquires a plurality of past date / times to be compared with a specific reference date / time (for example, the current time). The similar date / time extraction unit 10q calculates, for each of the randomly acquired past date / times, the sum of the absolute values of the differences obtained by subtracting the value of the specific index at the time retrogressed by “iΔT” from the past date / time from the value of the specific index at the time retrogressed by “iΔT” starting from the reference date / time. Then, the similar date / time extraction unit 10q extracts past time points with a small degree of divergence (that is, a large degree of similarity) that satisfy a predetermined criterion. Eventually, the similar date / time extraction unit 10q extracts past date / times in which the transition of the specific index related to water in the water supply-related facility is similar to the reference date / time.

[0045] The event extraction unit 10r extracts event information at the past date / times extracted by the similar date / time extraction unit 10q from the water quality / event information reception unit 10a. The event screening unit 10s selects and outputs event information with a high degree of involvement with the type of similarity calculation formula (type of specific index, that is, type of target variable) received by the similarity calculation formula type reception unit 10c from among the many extracted event information. The action procedure information extraction unit 10t searches for action procedure information using the event information selected by the event screening unit 10s as a key, and outputs the result to the action procedure information transmission unit 10f.

[0046] In addition, the action procedure information generation unit 10d aggregates the electronic manual browsing history / annotation information received from the electronic manual browsing history / annotation information reception unit 10b, the type of similarity calculation formula received from the similarity calculation formula type reception unit 10c, and the event information selected by the event screening unit 10s for each time stamp to generate action procedure information.

[0047] FIG. 9 is a diagram showing the data structure in the present embodiment. The water quality data storage unit 2 stores water quality data 2f. The water quality data 2f aggregates specific indexes such as the turbidity of the intake well and the water temperature of the receiving well for each date / time.

[0048] The event information storage unit 3 stores a plurality of event information 3a, a plurality of alarm information 3b, and a plurality of operation / driving information 3c. The event information 3a aggregates an alarm ID group, an operation amount, and an operation / driving information ID group for each date and time. The alarm information 3b is composed of an alarm ID and an alarm content. The operation / driving information 3c is composed of an operation / driving information ID and an operation / driving information content.

[0049] The document viewing information storage unit 6 stores a plurality of document viewing information 6a and a plurality of driver information 6b. The document viewing information 6a stores who viewed which part of a document (electronic manual) and when. That is, the document viewing information 6a stores a driver ID, a document ID, a page ID, a date and time, an annotator ID, and an annotation content. The driver information 6b stores a driver ID, a driver name, and a driver attribute (such as the driver's position and years of experience). Among the drivers of the device, those who viewed the electronic manual are the drivers, and among the drivers, those who added an annotation (comment) to the electronic manual are the annotators.

[0050] The document information storage unit 5 stores a plurality of electronic manuals 5a as documents. The electronic manual 5a stores a document ID, a document name, table of contents information, and a document file. The document file stores a plurality of page IDs and page contents. The page contents include a document in text format or image format.

[0051] The action procedure information storage unit 8 stores a plurality of action procedure information 8a indicating the past driving performance of drivers (actual operations / driving, pages of the electronic manual actually viewed), an event information / involvement degree table 8b, and a similar date and time information table 8c for a reference date and time.

[0052] The action procedure information 8a stores the action procedure information ID, the driver ID, the date and time when the action procedure was executed, the group of alarm IDs issued at that date and time, the group of operation / driving information IDs, and a plurality of action procedure contents. The action procedure content stores the document ID, the page ID, the order, the specific index, and the text of the action procedure. That is, the action procedure information 8a is, as a whole, a combination of the event information that occurred in the past and the page of the document viewed by the driver at that date and time. Further, among them, the event information indicates the alarm issued at that date and time and the operation / driving of the driver at that date and time. The event information - relevance table 8b stores, in a matrix format, the degree of relevance, which is the degree of involvement between the event information and the specific index (the target variable of the similarity calculation formula), for each combination of the event information and the specific index.

[0053] Now, for example, assume that the degree of relevance between the event "Alarm 1" and the specific index "turbidity of the intake well" is "1.0". Then, when the specific index "turbidity of the intake well" is selected, the event screening unit 10s preferentially selects the event "Alarm 1" from among many events.

[0054] As another example, assume that the degree of relevance between the event "Alarm 2" and the specific index "turbidity of the intake well" is "-1.0". Then, when the specific index "turbidity of the intake well" is selected, the event screening unit 10s preferentially excludes the event "Alarm 2" from among many events.

[0055] In this way, the action procedure information generation unit 10d of the action procedure information management server 10 normalizes the degree of relevance within the range of "-1.0 or more and less than 1.0". The action procedure information generation unit 10d determines the degree of relevance based on the past adoption frequency, etc. (especially the content of the annotations associated with the electronic manual actually viewed corresponding to that event).

[0056] Furthermore, the action procedure information generation unit 10d may use, as learning data, a large number of combinations of event information corresponding to the electronic manuals viewed by the skilled driver at past dates and times and to which the skilled driver has added positive annotations, and the specific indicators selected by the skilled driver at those past dates and times, and may perform machine learning on the following formula (2). "F" indicates that formula (2) is a kind of function.

[0057] [Equation 2] Degree of involvement = F(Specific indicator, Event information) …(2)

[0058] The similar date and time information table 8c for the reference date and time stores the reference date and time, the period (the period for randomly acquiring past dates and times), and a plurality of similar dates and times (past dates and times with a high degree of similarity to the reference date and time). The similar dates and times include rank, degree of similarity (or degree of deviation), and the date and time itself.

[0059] As is clear from the whole of FIG. 9, the water quality data 2f, the event information 3a, the document viewing information 6a, the action procedure information 8a, and the similar date and time table 8c for the reference date and time include "date and time". That is, these are mutually associated via the same date and time (timestamp) and can be aggregated with the same date and time as the key.

[0060] In the event information - degree of involvement table 8b of FIG. 10, one value of the degree of involvement is defined for a combination of one specific indicator and one piece of event information. However, more generally, one value of the degree of involvement may be defined for a combination of one or more specific indicators and one or more pieces of event information.

[0061] FIG. 10 shows the processing flow during the generation of action procedure information in the present embodiment. The processing flow is a procedure for accumulating action procedure information (norms for novice drivers) by the skilled driver.

[0062] In step S1, the water quality data collection server 1 collects water quality data. In step S2, the water quality monitoring control server 4 collects event information. In step S3, the driver information terminal 7 requests the manual information from the document information storage unit 2. Here, the driver information terminal 7 is operated by an experienced driver.

[0063] In step S4, the document information storage unit 2 transmits the electronic manual information to the driver information terminal 7. In step S5, the driver information terminal 7 accepts the similarity calculation formula (type of specific index) and the annotation for the electronic manual. In step S6, the monitoring camera 9 collects the driver behavior information. Specifically, the monitoring camera 9 captures the state of the driver viewing the electronic manual as a video or a still image, and recognizes and collects the manual name, page number, and in some cases, the gesture indicating the annotation. Also, the monitoring camera 9 captures the video or still image of the driver operating various devices, and recognizes and collects the type of the operating device and the presence or absence of the operation. These collected results become the driver behavior information here.

[0064] In step S7, the action procedure information management server 10 requests the event information from the water quality monitoring control server 4. In step S8, the water quality monitoring control server 4 transmits the event information to the action procedure information management server 10. In step S9, the action procedure information management server 10 requests the driver behavior information from the monitoring camera 9. In step S10, the monitoring camera 9 transmits the driver behavior information to the action procedure information management server 10.

[0065] In step S11, the action procedure information management server 10 requests the water quality data from the water quality data collection server 1. In step S12, the water quality data collection server 1 transmits the water quality data to the action procedure information management server 10. In step S13, the action procedure information management server 10 requests the driver behavior information from the driver information terminal 7.

[0066] In step S14, the driver information terminal 7 collects driver behavior information. Specifically, the driver behavior information here includes the electronic manual browsing history, the type of similarity calculation formula, the equipment operation location, etc. In step S15, the driver information terminal 7 transmits the driver behavior information to the action procedure information management server 10. In step S16, the action procedure information management server 10 screens (selects) event information according to the type of similarity calculation formula or annotation information. In step S17, the action procedure information management server 10 generates action procedure information using the screening result.

[0067] As is clear from the above, screening event information means, for each specific index selected by the driver, selecting event information with a high degree of involvement and event information with a low degree of involvement, and separating and storing the action procedure information corresponding to the event information with a high degree of involvement and the action procedure information corresponding to the event information with a low degree of involvement for each specific index.

[0068] Figure 11 is the processing flow when displaying action procedure information in this embodiment. The processing flow is a procedure for displaying the action procedure information of a skilled driver to an unskilled driver.

[0069] In step S21, the water quality data collection server 1 collects water quality data. In step S22, the water quality monitoring control server 4 collects event information. In step S23, the driver information terminal 7 receives a similarity calculation formula (type of specific index). In step S24, the action procedure information management server 10 requests event information from the water quality monitoring control server 4. In step S25, the water quality monitoring control server 4 transmits event information to the action procedure information management server 10.

[0070] In step S26, the action procedure information management server 10 requests water quality data from the water quality data collection server 1. In step S27, the water quality data collection server 1 transmits water quality data to the operation procedure information management server 10. In step S28, the operation procedure information management server 10 requests the type of similarity calculation formula (the type of specific index selected by the driver) from the driver information terminal 7. In step S29, the driver information terminal 7 transmits the type of similarity calculation formula to the operation procedure information management server 10.

[0071] In step S30, the similarity date / time extraction unit 10q of the operation procedure information management server 10 receives water quality data from the water quality / event information reception unit 10a. The similarity date / time extraction unit 10q calculates the similarity between the specific index such as turbidity at the reference date / time such as the current time and the specific index at each past date / time according to the similarity calculation formula selected (received) by the similarity calculation formula type reception unit 10c for the received water quality data. The similarity date / time extraction unit 10q extracts a predetermined number of past date / times in descending order of similarity.

[0072] In step S31, the event extraction unit 10r of the operation procedure information management server 10 extracts event information at the past date / times extracted by the similarity date / time extraction unit 10q from the water quality / event information reception unit 10a. Further, the event screening unit 10s of the operation procedure information management server 10 selects events from the extracted event information in which the degree of relevance to the specific index selected in step S23 satisfies a predetermined criterion and is large enough based on the event information / relevance table 8b (Fig. 9).

[0073] In step S32, the operation procedure information extraction unit 10t of the operation procedure information management server 10 searches for operation procedure information using the event information selected by the event screening unit 10s as a key. Here, the event information serving as the key is selected as those in which the degree of relevance to the specific index received in step S23 satisfies a predetermined criterion and is large enough.

[0074] In step S33, the action procedure information transmission unit 10f displays the action procedure information of the search result on the driver information terminal 7. The action procedure information displayed at this time corresponds to the event information having a high degree of involvement with the specific index selected by the driver at the reference date and time (see FIG. 12).

[0075] As is clear from the above, when an unskilled driver selects, for example, "intake well turbidity" as a specific index in step S23, only the action procedure information corresponding to the event information having a high degree of involvement with "intake well turbidity" is displayed in step S33.

[0076] FIG. 12 is a screen transition diagram of the driver information terminal 7 in the present embodiment. The upper part shows the top screen 21, the middle part shows the reason display screen 31, and the lower part shows the event information display screen 41.

[0077] The driver information terminal 7 accepts the driver's input of a target variable (any one of intake well turbidity, wellhead pH, etc. as a specific index) in the similarity calculation formula target variable column 22 of the top screen 21. Then, the driver information terminal 7 displays the recommended action procedure 23 on the top screen 21. If the input target variable (specific index) is different, the content of the recommended action procedure 23 displayed thereafter is also different.

[0078] The recommended action procedure 23 is a combination of a plurality of electronic manual pages, condition match degrees, and beginner recommended phrases. The electronic manual page is, for example, "Read pages 150 to 165 of Document X", which is the page of the electronic manual browsed by the driver at a past date and time. The condition match degree is, for example, "60%". The condition match degree here is the ratio of positive annotations among the annotations given to the electronic manual. Further, the condition match degree may be the similarity or divergence itself, or may be obtained by performing a predetermined correction (correction using the number of views in the most recent predetermined period, etc.) on the similarity or divergence. The beginner recommended phrase is, for example, "Recommended for beginners!". The driver information terminal 7 displays the current state 24. The current state is, for example, "The current state is an increase in intake well turbidity".

[0079] Now, assume that the driver has entered "intake well turbidity" in the similarity calculation formula target variable column 22 and selected the record (row) with a thick frame among the recommended action procedures 23. Then, the driver information terminal 7 displays the reason display screen 31.

[0080] The driver information terminal 7 displays the index transition graph 32 on the reason display screen 31. The index transition graph 32 shows the transition of the intake well turbidity during the period (reference period) corresponding to four sampling cycles with the reference date and time (current date and time) as the end point (thick line broken line). The index transition graph 32 also shows four cases with a high similarity between the intake well turbidity during the reference period and the intake well turbidity during the past period corresponding to four sampling cycles (the four broken lines other than the thick line). Furthermore, these four broken lines are extended further by three sampling cycles in the future direction in the past. Note that the "4" in the four broken lines corresponds to the fact that four past dates and times with a high similarity (low divergence) satisfying a predetermined criterion have been obtained, and has no direct relation to the "4" in the four sampling cycles.

[0081] The driver information terminal 7 displays the operation amount transition graph 33 on the reason display screen 31. The operation amount transition graph 33 shows the coagulant dosage during the reference period (thick line broken line). The operation amount transition graph 33 also shows the coagulant dosage during the period corresponding to seven sampling cycles before and after each of the four past dates and times with a high similarity (the four broken lines other than the thick line).

[0082] The driver information terminal 7 displays a past example list 34 on the reason display screen 31. "Standard" in the type column of the past example list 34 means the reference date and time (current date and time), and "Similar ○" means the past date and time. In the date and time column, the specific month, day, hour, and minute of the reference date and time and the past date and time are displayed. The deviation degree is displayed in the deviation degree column. In the driver column, the name or ID of the driver at the past date and time is displayed. In the content column, the page of the electronic manual viewed by the driver at the past date and time is displayed. The driver information terminal 7 displays a title 35 at a prominent position on the reason display screen 31. The title 35 contains a specific character string described on a page of the electronic manual. "Increase the coagulant injection rate by 5 mg / L" in the example of FIG. 12 is a countermeasure against the increase in the turbidity of the intake well.

[0083] When the driver selects the record with the thick frame in the past example list 34, the driver information terminal 7 displays the event information display screen 41. When the driver presses the "Back" button 36, the driver information terminal 7 displays the top screen 21. For the sake of explanation, now assume that the driver has selected a record including the type "Similar 1".

[0084] The driver information terminal 7 displays event information 42 on the event information display screen 41. The event information 42 is a time-series combination of the degree of involvement, alarm, and operation / driving at the past date and time corresponding to "Similar 1". The alarm is the alarm actually issued at the past date and time. The operation / driving is the operation / driving actually performed by the driver "B" at the past date and time.

[0085] In the first row, the degree of involvement "1.0" corresponds to the alarm "increase in turbidity". In the fourth row, the degree of involvement "1.0" also corresponds to the operation / driving "coagulant injection". This indicates that the driver who encountered "increase in turbidity of the intake well" at the reference date and time should pay attention to the first row and the fourth row as a result of the change in the turbidity of the intake well being sufficiently involved in the alarm "increase in turbidity" and the operation / driving "coagulant injection" which are the event information.

[0086] The degree of involvement “-1.0” in the second row indicates that the change in the turbidity of the intake well is not involved in the alarm “pump abnormality” at all. The degree of involvement “0.0” in the third row indicates that it cannot be said whether the change in the turbidity of the intake well is involved in the operation / driving “pump restart”. It is desirable for the driver information terminal 7 to hide records with such a small degree of involvement (in FIG. 12, an example of displaying them is shown for explanatory purposes). If the event screening unit 10s does not exist, the number of records of the event information 42 will become extremely large.

[0087] The driver information terminal 7 may predict the change in a specific index after the reference date and time, and based on the result, display the alarm 43 that is likely to be issued in the future and the operation / driving 44 that is likely to be performed in the future.

[0088] When the driver presses the “return” button 45, the driver information terminal 7 displays the reason display screen 21.

[0089] (Effect of this embodiment) (1) The action procedure information management device can limit the event information at a past time point when the specific index is similar to the reference time point to those related to the specific index. (2) The action procedure information management device enables the driver to select a specific index. (3) The action procedure information management device can aggregate the event information and the document viewing information having the same date and time, and generate the action procedure information. (4) The action procedure information management device can determine the degree of involvement between the specific index and the event information based on the annotation for the electronic manual.

[0090] (5) The action procedure information management device can be applied to a water purification plant or a sewage treatment plant. (6) The action procedure information management device can use, as the event information, an alarm that is easy to appear externally or the content of the driver's operation / driving. (7) The action procedure information management device can define the degree of involvement between the specific index that is highly interesting to the driver and the event information.
