[0005] Patent Document 2: Japanese Patent Application Publication No. 2018-112903 Summary of the invention

[0006] Technical issues to be solved by the invention

[0007] However, in the past, only by understanding the various parameters configured on the physical map from all aspects can the operating status of the factory equipment be understood. This sometimes not only puts too much burden on the operators, but also makes it difficult for non-professionals to accurately understand the operating status of the factory equipment.

[0008] Here, the device of Patent Document 1 merely calculates the maintenance priority, which cannot be said to be sufficient for grasping the operating status of the plant equipment. In addition, the device of Patent Document 2 needs to calculate the estimated value or the predicted value, so it is expected to grasp the operating status of the plant equipment with a simpler structure.

[0009] One of the exemplary purposes of one embodiment of the present invention is to provide a support device, a display device, a support method, and a support program that can easily grasp the operating status of plant equipment with a simple structure.

[0010] Means for solving technical problems

[0011] In order to solve the above-mentioned problems, a support device involved in one embodiment of the present invention is used to grasp the operating status of factory equipment, and comprises: a data acquisition unit, which acquires process data of factory equipment; a summary unit, which summarizes the dimensions of the process data acquired by the data acquisition unit; and a display unit, which displays the summary data summarized by the summary unit.

[0012] According to the above method, the dimensions of the process data are summarized by the summary unit, and the summary data summarized by the summary unit is displayed on the display unit. Thus, since the summary data in which the dimensions of the process data are summarized is displayed, compared with the case of displaying multi-dimensional process data, for example, it is not too much burden on the operator, and the operating status of the factory equipment can be easily grasped. In addition, since the display is based on the summary data, even non-professionals can grasp the operating status of the factory equipment. In addition, since the summary data in which the dimensions of the process data are summarized is used, it is possible to support the grasp of the operating status of the factory equipment with a simple structure.

[0013] Another embodiment of the present invention is a display device. The device is a display device for grasping the operating status of factory equipment, which can display the following data in a comparable manner: summary data that summarizes the dimensions of process data of factory equipment; and past summary data that integrates logged events related to factory equipment.

[0014] Another embodiment of the present invention is a support method. The method is a support method for grasping the operating status of factory equipment, which includes the following steps: acquiring process data of factory equipment through a data acquisition unit; aggregating dimensions of the process data acquired by the data acquisition unit through a summary unit; and displaying the summary data summarized by the summary unit through a display unit.

[0015] Another embodiment of the present invention is a computer program product, including a support program executed by a computer in order to understand the operating status of factory equipment, wherein the program causes the computer to execute the following steps: obtaining process data of the factory equipment; summarizing the dimensions of the obtained process data; and displaying the summarized data.

[0016] Another embodiment of the present invention is a factory equipment. The factory equipment includes: a data acquisition unit that acquires process data from a sensor installed in the factory equipment and a control device that controls the factory equipment; a summary unit that summarizes the dimensions of the process data acquired by the data acquisition unit; and a display unit that displays the summary data summarized by the summary unit.

[0026] Hereinafter, the embodiments of the present invention will be described with reference to the accompanying drawings, but the following embodiments are not intended to limit the scope of the claims, and not all feature combinations described in the embodiments are essential to the solution of the invention. In each of the drawings, the same or identical constituent elements, components, and processes are marked with the same symbols, and repeated descriptions are appropriately omitted.

[0027] Figures 1 to 6 1 is a diagram for explaining a support device and a support method according to an embodiment of the present invention. Figure 1 is a diagram showing a configuration of a support device 10 according to an embodiment of the present invention. Figure 2 is a diagram showing an example of the hardware configuration of the support device 10. Figure 3 and Figure 4 is a flowchart showing an example of a support method by the support device 10. Figure 5 and Figure 6 This is a diagram for explaining an example of a supporting method.

[0028] The support device 10 is used to grasp the operating status of factory equipment. As an example of factory equipment, power generation plant equipment, incineration plant equipment or chemical plant equipment can be cited. The factory equipment is equipped with a processing device (not shown) for performing a predetermined process (for example, power generation processing, incineration processing, chemical processing, etc.). Any process data can be used in the factory equipment. Process data is, for example, data of process values ​​such as temperature, pressure, air volume, concentration or composition. Specifically, the process value of the process data may include a measured value detected by a sensor installed in the factory equipment and an operating amount based on the difference between a set value and a measured value at a position detected by the sensor. The process data obtained from the factory equipment is multidimensional data with more than hundreds of types.

[0029] The support device 10 includes a dimension aggregation mechanism 20 and a storage unit 30. The dimension aggregation mechanism 20 is connected to a plurality of sensors (not shown) provided in the factory equipment and a control device (not shown) for controlling the factory equipment, and acquires process data from the sensors and the control device, aggregates the acquired process data, and displays the aggregated data. The storage unit 30 stores various data related to the factory equipment, and also stores various data calculated or acquired by the dimension aggregation mechanism 20.

[0030] The support device 10 has pre-installed therein a predetermined program required for executing the support method of this embodiment. Figure 2 1 shows an example of the hardware structure of the support device 10. Specifically, the support device 10 can use a general-purpose or dedicated computer including a CPU 101, a ROM 102, a RAM 103, an external memory 104, a user interface 105, a display 106, a printer 107, and a communication interface 108. The CPU 101 performs calculations based on information input by an operator through the user interface 105, and outputs the calculation results to the display 106 or the printer 107. The operator can recognize the output and input the required information to the support device 10 through the user interface 105.

[0031] The support device 10 may be composed of a single computer or a plurality of computers distributed on a network. Regarding the support device 10, for example, the CPU executes a predetermined program (a program that specifies the support method involved in this embodiment) stored in the above-mentioned ROM, RAM, external memory, etc. or downloaded via a communication network, so that the support device 10 can perform the functions of various functional blocks or various steps described later.

[0032] Hereinafter, various functional blocks of the dimension aggregation unit 20 and the storage unit 30 in the support device 10 will be described.

[0033] The dimension aggregation mechanism 20 includes a data acquisition unit 21, a rule generation unit 22, an aggregation unit 23, an event registration unit 24, a data integration unit 25, and a display unit 26. The storage unit 30 includes a process data storage unit 31, a dimension aggregation rule storage unit 32, and an aggregation data storage unit 33.

[0034] The data acquisition unit 21 acquires process data of the plant equipment. The process data is, for example, data indicating the time-dependent changes of the process value. In this case, the process data may be the changes of the continuous process values ​​separated by a predetermined time interval. The process data is multidimensional data. The process data acquired by the data acquisition unit 21 is stored in the process data storage unit 31 together with the time information of the plant equipment.

[0035] The rule generation unit 22 generates a dimension aggregation rule for aggregating the dimensions of the process data stored in the process data storage unit 31 into a smaller number of dimensions. The dimension aggregation rule generated by the rule generation unit 22 is stored in the dimension aggregation rule storage unit 32 together with the time information of the plant equipment.

[0036] The algorithm for dimensional aggregation is not particularly limited, and for example, principal component analysis can be applied. At this time, the dimensional aggregation rule determines the 1st to nth (n is an integer greater than 2) principal components for the process data stored in the process data storage unit 31. The generation of dimensional aggregation rules by the rule generation unit 22 can be performed periodically, or the dimensional aggregation rule can be generated (or updated) for the process data stored in the process data storage unit 31 each time the dimensional aggregation mechanism 20 aggregates the dimensions of the process data in order to grasp the operating status of the factory equipment. The number of principal components in the dimensional aggregation rule is not limited, and for example, it can be two principal components, the first principal component and the second principal component, or it can be three principal components, the first principal component to the third principal component. By reducing the number of principal components, the operating status of the factory equipment can be displayed more simply.

[0037] The summarizing unit 23 summarizes the dimensions of the process data acquired by the data acquisition unit 21. For example, the summarizing unit 23 summarizes the dimensions of the process data based on the dimension summarizing rule generated by the rule generating unit 22. Thus, summary data having a dimension less than the dimension of the process data is generated. The process data summarized by the summarizing unit 23 is process data of a predetermined period for which the operating status of the factory equipment is to be understood. For example, the summarizing unit 23 can generate the current summary data from the current process data. The summary data generated in this way is stored in the summary data storage unit 33. In addition, the summary data can be displayed in a coordinate system having each principal component as a coordinate axis. For example, the summary data summarized into two dimensions consisting of the first principal component and the second principal component can be displayed in a two-dimensional coordinate system.

[0038] The event registering unit 24 registers events related to the plant equipment. The event registering unit 24 registers events, for example, by receiving input from an operator via the user interface 105. The content of the event varies depending on the operating conditions of the plant equipment, and can be roughly divided into a good state or a bad state for the operation of the plant equipment. As specific contents of the event, for example, there may be a trial operation of the plant equipment (good state), operation just after a regular inspection (good state), a fault state (bad state), a state where the actual operation of the plant equipment deviates from the set value (bad state), and operation when the plant equipment is re-operated (bad state). The event registering unit 24 may register the event after establishing an association with the good or bad information of the operating conditions of the plant equipment. The good or bad information is not limited to a sign indicating good or bad, etc., as long as the operator can recognize its content and can grasp the good or bad information for the operation of the plant equipment. In addition, the event registered by the event registering unit 24 is not limited to any one of the good and bad states for the operation of the plant equipment, but may also belong to an unknown state other than this.

[0039] The data integration unit 25 integrates the events registered by the event registration unit 24 and the summary data compiled by the aggregation unit 23. The summary data integrated with the events is stored in the summary data storage unit 33. In addition, it is not limited to integrating all the summary data compiled by the aggregation unit 23 with the events. For example, only the summary data of a predetermined time and the events occurring at the predetermined time may be integrated.

[0040] The display unit 26 (an example of a display device) displays the summary data summarized by the summary unit 23. For example, if the summary data is summarized into two dimensions consisting of the first principal component and the second principal component, the summary data can be displayed in a two-dimensional coordinate system through the display unit 26. In addition, the display unit 26 displays the summary data at a predetermined time for grasping the operating status of the factory equipment and the summary data before that time in a comparable manner. At this time, the past summary data and the content of the event integrated with it can be displayed together (and good and bad information can also be displayed as needed). In addition, the display unit 26 can also display the changes in the summary data when an action is performed on the factory equipment. The display of the change in the summary data is performed, for example, by showing the coordinate-based information before and after the action of the summary data in the coordinate system.

[0041] In addition, the specific operations of the various structures of the dimension aggregation unit 20 and the storage unit 30 will be described in detail in the supporting method described later.

[0042] As a support method according to one embodiment of the present invention, reference is made to Figures 3 to 6 An example of the operation of the usage support device 10 will be described. Figure 3 This is an example of the entire support method involved in this embodiment. Figure 4 An example of a method for integrating events and aggregating data is shown in FIG. Figure 5 and Figure 6 2 shows an example of a display method on the display unit 26 before and after an operation is performed on the plant equipment.

[0043] In the following method, an example of a method is described in which the current summary data is compared with the past summary data (good status during trial operation), the past summary data in good status is used as a target, and the factory equipment is operated in a manner close to the target. In addition, an example of an algorithm using principal component analysis as a dimensional summary is described.

[0044] exist Figure 3 In the process, first, the current process data of the plant equipment is acquired by the data acquisition unit 21 (S10). The current process data acquired by the data acquisition unit 21 is stored in the process data storage unit 31. In addition to the current process data, the process data storage unit 31 also stores the past process data of a predetermined period. The acquisition of process data by the data acquisition unit 21 can be performed by receiving input from the operator via the user interface 105.

[0045] Next, the dimensions of the current process data are summarized by the summary unit 23 (S11). Specifically, the summary unit 23 summarizes the dimensions of the current process data read from the process data storage unit 31 based on the dimension summary rule generated by the rule generation unit 22, thereby generating the current summary data. The dimension summary rule is generated for the current and past process data stored in the process data storage unit 31, and includes, for example, the content of determining each principal component. Then, the summary unit 23 calculates the principal component score of each principal component determined by the rule generation unit 22, and uses the principal component score as the summary data. The summary data generated in this way is stored in the summary data storage unit 33.

[0046] Next, the display unit 26 displays the current summary data and the past summary data integrated with the event in a comparable manner ( S12 ). The display unit 26 may display in response to an input via the user interface 105 .

[0047] Here, reference Figure 4 An example of a method for integrating events and aggregating data is described. First, an event is logged in through the event logging unit 24 (S20). Regarding the logging of events, the operator inputs the content through the user interface 105 to log the event. The event logging of the event logging unit 24 can log various events that can be imagined in advance, or can log in at the moment when the event occurs due to the operating status of the factory equipment. In addition, the event can be logged after establishing an association with the good or bad information of the operating status of the factory equipment. The data of the logged event is stored in the storage unit 30.

[0048] Next, the logged events and summary data are integrated by the data integration unit 25 (S21). Step S21 can be performed based on the input of the operator via the user interface 105. For example, when the summary data is data generated during the test run of the plant equipment, the summary data is stored in the summary data storage unit 33 after establishing a correspondence relationship with the event "test run" (S22).

[0049] The display unit 26 can display the past summary data stored in the summary data storage unit 33 and the events integrated therewith together ( S23 ), and can also display the past summary data together with the current summary data ( Figure 3 S12).

[0050] Here, Figure 5 1 is a diagram showing an example of a display form of the display unit 26 in step S12. Figure 5 The display area 40 of the display unit 23 displays the current summary data summarized by the summary unit 23 (in Figure 5 The display area 40 includes a display area 50 for displaying a coordinate system corresponding to the dimension of the summary data summarized by the summary unit 23, and display areas 70, 80, and 90 for displaying information related to the summary data.

[0051] The display area 50 shows a coordinate system with the first principal component 52 and the second principal component 54 as two-dimensional coordinate axes. In the coordinate system of the display area 50, a plurality of summary data 60 are plotted based on the principal component scores of the principal components. The plurality of summary data 60 includes the current summary data 62a and the target summary data 64 (in Figure 5 In the example, except for the summary data 62a and 64, other past summary data are indicated by dots. Moreover, any of these multiple summary data 60 is associated with the predetermined event 56 and the events 58a, 58b, and 58c. In this example, the event 56 including the target summary data 64 is a "test run" event, and the events 58a, 58b, and 58c are "fault state" events with different fault causes. Furthermore, the event 56 is an event in which the plant equipment is identified as being in a good state, and the events 58a, 58b, and 58c are events in which the plant equipment is identified as being in a deteriorated state.

[0052] The display area 70 displays information about the current summary data 62a and the target summary data 64. The display area 80 displays information about at least one past summary data similar to the current summary data 62a. The display area 90 displays information about at least one past summary data not similar to the current summary data 62a.

[0053] The display area 70 shows the similarity between the current summary data 62a and the target summary data 64 (in Figure 5 In the example of , it is "70%"). In addition, past summary data that is similar or dissimilar to the current summary data 62a is displayed in an arranged manner in each display area 80, 90. In addition, the operation time of the plant equipment of the summary data and the support information for grasping the operation status of the plant equipment are displayed in these display areas 70 to 90. The support information includes, for example, events that have a corresponding relationship with the summary data, the operation status of the plant equipment at this time, the content of the action performed at this time or the result after the action is performed, or information related to the original data of the summary data (that is, various process data, etc.). This support information can be used to support the determination of the action to be performed on the plant equipment.

[0054] The operator uses the naked eye to identify Figure 5 The display area 40 shown in FIG. 4 is used to determine whether the current summary data 62 a is similar to the target past summary data 64 ( S13 ). Figure 5 In the example, the target past summary data 64 is associated with the event 56 of "trial operation" in which the plant equipment is identified as being in a good state, so the operator operates the plant equipment in such a way that the current summary data 62a is closer to the target past summary data 64.

[0055] exist Figure 5 In the example shown, the similarity between the current summary data 62a and the target summary data 64 is displayed as "70%". If the operator who visually recognizes the display area 40 of the display unit 26 determines that the current summary data 62a cannot be said to be similar to the target summary data 64 (No in S13), the input of the operator via the user interface 105 is used as an opportunity to make the factory equipment perform a predetermined action (S14). At this time, for example, the support information displayed on the display unit 26 is taken into consideration to perform the predetermined action on the factory equipment. Specifically, when the operator performs the predetermined action on the factory equipment, the display area 80 in the display unit 26 can be recognized by the naked eye to consider the support information of at least one past summary data that has a high similarity with the current summary data 62a (for example, which event has a corresponding relationship, the action performed or its result, etc.).

[0056] After the operation is performed, the process returns to step S12 , and the display unit 26 displays the current summary data and the past summary data integrated with the event in a comparable form again ( S12 ).

[0057] Here, Figure 6 2 is a diagram showing an example of the display mode of the display unit 26 after the operation is performed on the plant equipment in step S14. Figure 6 In the display area 40 of , the date of the current summary data summarized by the summary unit 23 is Figure 5 The next day (i.e., December 4, 2018). Furthermore, the coordinate system of the display area 50 shows the direction in which the current summary data 62b has changed from the previous day's summary data 62a in the coordinate system, and the changes in the positional relationship of the current summary data 62b relative to the target past summary data 64 can be compared. As a result of the action performed in step S14, the similarity between the current summary data 62b and the target past summary data is displayed as "80%". It can be seen that it is close to the target past summary data, so it can be recognized that the directionality of the action performed in step S14 is accurate. In this way, steps S12 to S14 are repeated until it is determined to be similar to the target past summary data.

[0058] If it is determined that the data is similar to the target past summary data (good state) (Yes in S13 ), the process ends.

[0059] As described above, the support device involved in this embodiment summarizes the dimensions of process data by the summary unit, and displays the summary data summarized by the summary unit on the display unit. Thus, the summary data summarizing the dimensions of the process data is displayed, so compared with the case of displaying multi-dimensional process data, for example, it is not too much burden on the operator, and the operating status of the factory equipment can be easily grasped. In addition, since it is based on the display of the summary data, even non-professionals can grasp the operating status of the factory equipment. In addition, since the summary data summarizing the dimensions of the process data is used, it is possible to support the grasp of the operating status of the factory equipment with a simple structure.

[0060] The present invention is not limited to the above-mentioned embodiment, and various modifications are possible. In the above-mentioned embodiment, an example of generating two-dimensional summary data composed of the first principal component and the second principal component is described, but the number of principal components is not limited to this, for example, three-dimensional summary data composed of the first principal component, the second principal component, and the third principal component may be generated. In this case, Figure 5 and Figure 6The three-dimensional coordinate system is displayed in the display area 50. In addition, the algorithm for dimension aggregation is not limited to principal component analysis, and other statistical methods can also be used.

[0061] Furthermore, the operation of the support device 10 is not limited to all operations being automatically performed by computer calculations, but includes at least a portion of the operations being performed manually by an operator. Figure 5 and Figure 6 The display method is just an example and is not limited to this.

[0062] Furthermore, the support device 10 shown in the above embodiment may be a device provided separately from the factory equipment, or may be a device assembled in the factory equipment itself. In the case of a device assembled in the factory equipment itself, the factory equipment includes a processing device for performing predetermined processing and a control device for controlling the processing device, and also includes the structure of various functional blocks of the dimension aggregation mechanism 20 and the storage unit 30 in the support device 10 shown in the above embodiment.

[0063] The above embodiments can be appropriately combined, changed or improved according to the application, and the present invention is not limited to the above embodiments. It is clear from the description of the claims that such combinations, changes or improvements can also be included in the technical scope of the present invention.
