DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. In the following, the scope necessary for the explanation to achieve the object of the present invention will be shown in a schematic manner, and the scope necessary for the explanation of the relevant part of the present invention will be mainly explained, and the parts that are omitted from the explanation will be based on the publicly known technology.

[0011] (Data Management System) FIG. 1 is an overall configuration diagram showing an example of a data management system 1 according to an embodiment of the present invention. The data management system 1 functions as a system for managing a fluid pressure driven valve 10 as an example of equipment. The data management system 1 mainly includes the fluid pressure driven valve 10 as a measurement target, a physical quantity measuring device 2 for measuring a physical quantity of the fluid pressure driven valve 10, a mobile terminal device 3 used by a maintenance worker M (an inspector / repair worker of the fluid pressure driven valve 10, etc.) as an inputter, a data management device 4 configured to be able to communicate with the fluid pressure driven valve 10 and the mobile terminal device 3, etc. and used by a maintenance manager A (a manager of the inspection / repair worker, etc.), and an equipment manager terminal device 7 configured to be able to communicate with the data management device 4, etc. and used by an equipment manager U (a manager or owner of the fluid pressure driven valve 10, etc.) as a report target.

[0012] In this embodiment, the device will be described by taking the fluid pressure driven valve 10 as an example, but the device is not limited to the fluid pressure driven valve 10, and general devices such as other valves such as breathing valves, rotating machines, tanks, etc. may be used. The device includes one or more components that constitute the device. The details of the fluid pressure driven valve 10 will be described later.

[0013] The physical quantity measuring device 2 acquires physical quantity information obtained by measuring the physical quantities of the fluid pressure driven valve 10 or components constituting the fluid pressure driven valve 10 that are the measurement target. The physical quantity measuring device 2 may be incorporated in the fluid pressure driven valve 10, or may be provided in the fluid pressure driven valve 10 as a device separate from the fluid pressure driven valve 10. The physical quantity information is, for example, measurement data obtained from various sensors or the like installed in the fluid pressure driven valve 10, or processed data obtained by processing the measurement data. In this case, the physical quantity information may be measurement data obtained from the sensors (hereinafter, including processed data) recorded at a predetermined sampling period or sampling frequency.

[0014] The mobile terminal device 3 is a device used by a maintenance worker M located near the installation location of the fluid pressure driven valve 10, and is configured, for example, with a portable computer. Programs such as applications and browsers are installed in the mobile terminal device 3, and the mobile terminal device 3 accepts various input operations and displays various information on a display screen (an input screen for impression information, etc.). When the mobile terminal device 3 accepts an input operation of impression information by the maintenance worker M with respect to the fluid pressure driven valve 10, the mobile terminal device 3 uploads to the data management device 4 the impression information, the input time when the impression information was input by the maintenance worker M, and device identification information for identifying the fluid pressure driven valve 10 as the input target of the impression information.

[0015] The data management device 4 is composed of, for example, a server-type computer or a cloud-type computer. The data management device 4 has a management control unit 41 that creates management information by associating the physical quantity information received from the physical quantity measuring device 2 and the impression information and input time received from the mobile terminal device 3 with each device or each component identified based on the device identification information, and a management storage unit 42 that stores the management information created by the management control unit 41. The details of the data management device 4 will be described later.

[0016] The impression information may be voice data or character data (text data) intuitively uttered by the maintenance worker M about his / her impression of the fluid pressure driven valve 10. In the case of voice data, it is preferable for the mobile terminal device 3 to convert the voice data into character data. The impression information may also be biometric data such as the amount of sweating or heart rate of the maintenance worker M. In the case of biometric data, it is preferable for the mobile terminal device 3 to convert the biometric data into character data such as "abnormal" when the amount of sweating or heart rate is high, and "no abnormality" when the amount of sweating or heart rate is low. The input time may be obtained from a clock or the like built into the mobile terminal device 3.

[0017] The device identification information is information for identifying the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10. Examples of the device identification information include, but are not limited to, a device identification number such as an ID number uniquely assigned to each fluid pressure driven valve 10 or each component of the fluid pressure driven valve 10, and terminal location information that identifies the location of the mobile terminal device 3.

[0018] The device identification number is acquired, for example, by the following method. For example, if the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 has a code image (one-dimensional code, two-dimensional code, etc.) or an ID tag (RFID, etc.) that records the device identification number, the address of the information transmission destination, etc., the mobile terminal device 3 may acquire the device identification number by a code recognition function for a code image captured by the camera of the mobile terminal device 3 or a tag reading function for an ID tag. If the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 has a sticker on which the device identification number is printed, the mobile terminal device 3 may acquire the device identification number by a character recognition function for a sticker captured by the camera of the mobile terminal device 3. The mobile terminal device 3 may acquire the device identification number by accepting an input operation by the maintenance worker M to input the device identification number. As for the terminal location information, the mobile terminal device 3 may acquire the terminal location information by a position detection function such as GPS, Wi-Fi, a beacon, an inertial navigation sensor, or a geomagnetic sensor of the mobile terminal device 3.

[0019] When the device identification information is a device identification number, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is directly identified by the device identification number. When the device identification information is terminal location information, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is indirectly identified by the terminal location information. Specifically, the maintenance manager A registers the registered location information of the fluid pressure driven valve 10 in advance in the data management device 4. The mobile terminal device 3 transmits the terminal location information as device identification information to the data management device 4 together with the impression information and the input time. The data management device 4 compares the terminal location information received from the mobile terminal device 3 with the registered location information of the fluid pressure driven valve 10 registered in advance, thereby identifying the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 having registered location information closest to the terminal location information. In either case, the data management device 4 From among the multiple fluid-pressure driven valves 10 or the multiple components of the fluid-pressure driven valves 10, the fluid-pressure driven valve 10 or the component of the fluid-pressure driven valve 10 that is the target of input of impression information can be identified based on the device identification information received from the mobile terminal device 3, and management information can be created by associating the physical quantity information received from the physical quantity measuring device 2 with the impression information and input time received from the mobile terminal device 3.

[0020] The equipment manager terminal device 7 is a device used by an equipment manager U located in a remote location away from the installation location of the fluid pressure driven valve 10, and is configured as, for example, a stationary computer or a portable computer. The equipment manager terminal device 7 has applications, browsers, and other programs installed, accepts various input operations, and displays various information (management information, daily management reports, etc.) on the display screen.

[0021] The network 8 is configured by wired communication or wireless communication according to any communication standard, or a combination of wired communication and wireless communication. Specifically, for example, a standardized communication network such as the Internet, a communication network managed within a building such as a local network, or a combination of these communication networks can be used.

[0022] In addition, the data management system 1 may further include a machine learning device 5 that generates a learning model based on the management information created by the data management device 4, and an information processing device 6 that predicts the state of the hydraulically driven valve 10 using the learning model learned by the machine learning device 5.

[0023] The machine learning device 5 operates as a subject of the learning phase of machine learning, and, for example, acquires a learning data set used for machine learning created by the data management device 4 from physical quantity information and impression information associated with the physical quantity information, and generates by machine learning a learning model used in the information processing device 6. The learned learning model is provided to the information processing device 6 via the network 8, a recording medium, or the like.

[0024] The information processing device 6 operates as the subject of the machine learning inference phase, and predicts the state of the fluid pressure driven valve 10 from physical quantity information during operation using the learning model generated by the machine learning device 5, and transmits the predicted state information of the fluid pressure driven valve 10 to at least one of the data management device 4 or the equipment administrator terminal device 7, etc.

[0025] Each of the devices 3 to 7 is configured, for example, as a general-purpose or dedicated computer (see FIG. 5 described later), and is configured to be able to transmit and receive various data to and from each other via the network 8. The number of each of the devices 3 to 7 is not limited to the example in FIG. 1, and may be one or more.

[0026] (Fluid pressure operated valve 10) 2 is a schematic diagram showing an example of a fluid pressure driven valve 10 according to an embodiment of the present invention. The fluid pressure driven valve 10 includes a main valve 30, a drive device 40, and a solenoid valve 50.

[0027] The fluid pressure driven valve 10 shown in Fig. 2 employs an airless close system. During normal operation, the main valve 30 is opened by supplying air A (intake air) from the air supply source 13 to the drive unit 40 via the solenoid valve 50, and during emergency stop or test operation, the main valve 30 is closed by discharging air A (exhaust air) from the drive unit 40 via the solenoid valve 50. Note that the fluid pressure driven valve 10 may employ an airless open system, in which case the main valve 30 is closed by supplying air A to the drive unit 40 and opened by discharging air A from the drive unit 40.

[0028] The fluid pressure driven valve 10 includes a first air pipe 130 connecting the air supply source 13 and the solenoid valve 50, and a second air pipe 130 connecting the solenoid valve 50 and the drive unit 40 as a flow path for the air A. A pipe 131 is provided. The driving fluid is not limited to the above air A, but may be other gases or liquids (for example, oil).

[0029] The fluid pressure driven valve 10 is connected to a communication cable 140 for transmitting and receiving various data between the external device 14 and the solenoid valve 50 , and a power cable 150 for supplying power from the external power source 15 to the solenoid valve 50 .

[0030] The external device 14 is a device that transmits and receives various information to and from the fluid pressure driven valve 10. The external device 14 is composed of, for example, a computer for facility management (including a local server and a cloud server), a computer for an operator, a storage device or storage medium for storing data, etc. Any communication standard may be adopted for communication between the external device 14 and the solenoid valve 50, and wireless communication may also be used. In this embodiment, the external device 14 corresponds to the data management device 4, etc.

[0031] A ball valve is used for the main valve 30 shown in Fig. 2. Specifically, the main valve 30 includes a valve box 32 disposed midway through the piping 11, and a ball-shaped valve element 31 rotatably provided within the valve box 32, with the valve stem 12 connected to the upper part of the valve element 31. As the valve stem 12 is rotated from 0 degrees to 90 degrees, the valve element 31 rotates within the valve box 32, and the main valve 30 is switched between a fully open state (the state shown in Fig. 2) and a fully closed state. Note that the valve used as the main valve 30 is not limited to a ball valve, and may be, for example, a butterfly valve or other on-off valve.

[0032] The drive device 40 shown in Fig. 2 employs a single-acting air cylinder mechanism. The drive device 40 includes, as specific configurations, a cylinder 400 having a spring chamber 470 and a cylinder chamber 480, a pair of pistons 420A, 420B connected via a piston rod 410 that is provided in the cylinder 400 so as to be capable of reciprocating linearly, a coil spring 430 provided in the spring chamber 470 on the first piston 420A side, an air supply / discharge port 440 connected to the cylinder chamber 480 on the second piston 420B side, and a transmission mechanism 450 provided at a portion where the valve shaft 12 arranged to penetrate the cylinder 400 in the radial direction and the piston rod 410 intersect at right angles. The drive device 40 is not limited to a single-acting type, and may be configured in other types, such as a double-acting type.

[0033] The first piston 420A is biased by a coil spring 430 in a direction to close the main valve 30. The second piston 420B is pressed in a direction to open the main valve 30 against the biasing force of the coil spring 430 by air A (supply air) supplied from an air supply / discharge port 440. The transmission mechanism 450 is composed of a rack and pinion mechanism, a Scotch yoke mechanism, a link mechanism, a cam mechanism, etc., and converts the reciprocating linear motion of the piston rod 410 into rotational motion and transmits it to the valve shaft 12.

[0034] 2 employs a two-position normally closed type three-way solenoid valve ("open" when energized, "closed" when de-energized). The solenoid valve 50 is specifically configured to include, inside the housing 500, a spool portion 510 that switches the flow path through which the air A flows, a solenoid portion 520 that displaces the spool portion 510 depending on the energized state (when energized or de-energized), and a sensor group 530 that measures physical quantities and state quantities of each portion of the solenoid valve 50. The solenoid valve 50 is not limited to a two-position normally closed type three-way solenoid valve, but may be a three-position type, a normally open type, a four-way solenoid valve, or the like, and may be configured in various configurations based on any combination.

[0035] The accommodating section 500 functions as a housing for the indoor or explosion-proof solenoid valve 50. The accommodating section 500 includes a shaft insertion port 501 into which the valve shaft 12 (third shaft 12c) is inserted, and a cable insertion port 502 into which the communication cable 140 and the power cable 150 are inserted.

[0036] The spool portion 510 has an input port 511 connected to the air supply source 13 via a first air pipe 130, an output port 512 connected to the drive unit 40 via a second air pipe 131, and an exhaust port 513 for discharging exhaust air from the drive unit 40.

[0037] When energized, the solenoid portion 520 displaces the spool portion 510 so as to connect the input port 511 and the output port 512, and when not energized, the solenoid portion 520 displaces the spool portion 510 so as to connect the output port 512 and the exhaust port 513.

[0038] The sensor group 530 is disposed at various locations inside the accommodation section 500. The sensor group 530 includes, for example, a first pressure sensor 531 that measures the fluid pressure of the air A flowing through a first flow path 503 that communicates with the input port 511, a second pressure sensor 532 that measures the fluid pressure of the air A flowing through a second flow path 504 that communicates with the output port 512, and a main valve opening sensor 533 that measures the rotation angle when the valve shaft 12 (third shaft 12c) rotates and acquires valve opening information of the main valve 30 according to the rotation angle.

[0039] The main valve opening sensor 533 is composed of, for example, a magnetic sensor, and measures the strength of the magnetic field generated by the permanent magnet 120 attached to the valve shaft 12 (third shaft 12c), and obtains valve opening information of the main valve 30 according to the magnetic field strength.

[0040] The valve shaft 12 is formed in a rotatable shaft shape and is composed of a first shaft 12a, a second shaft 12b, and a third shaft 12c. Both ends of the first shaft 12a are connected to the second shaft 12b and the third shaft 12c, respectively, via couplings, connectors, etc., and the first shaft 12a, the second shaft 12b, and the third shaft 12c are arranged coaxially. The first shaft 12a is arranged to pass through the drive unit 40 and is driven by the drive unit 40. The second shaft 12b is connected to the first shaft 12a and is connected to the main valve 30. The third shaft 12c is connected to the first shaft 12a and is inserted into and supported by the housing portion 500 of the solenoid valve 50. The valve shaft 12 performs a rotational motion as a whole in synchronization with the driving of the first shaft 12a by the drive unit 40.

[0041] In the fluid pressure driven valve 10 having the above configuration, when the solenoid valve 50 is in an energized state, air A (supply air) from the air supply source 13 flows through the first air piping 130, the input port 511, the output port 512, and the second air piping 131 in this order, and is supplied to the air supply / discharge port 440, thereby pressing the second piston 420B and compressing the coil spring 430. Then, when the first shaft 12a (valve shaft 12) is rotated via the piston rod 410 and the transmission mechanism 450 by an amount corresponding to the movement of the piston rod 410 in response to the compression of the coil spring 430, the valve element 31 rotates within the valve box 32, and the main valve 30 is operated to a fully open state.

[0042] On the other hand, when the solenoid valve 50 is in a non-energized state, the air A (exhaust) in the cylinder 400 flows from the air supply / exhaust port 440 through the second air pipe 131, the output port 512, and the exhaust port 513 in this order, and is discharged to the outside air, thereby reducing the pressing force of the second piston 420B and causing the coil spring 430 to restore from the compressed state. Then, when the first shaft 12a (valve shaft 12) is rotated via the transmission mechanism 450 by the amount of movement of the piston rod 410 in response to the restoration of the coil spring 430, the valve element 31 rotates in the valve box 32, and the main valve 30 is operated to the fully closed state.

[0043] Fig. 3 is a schematic block diagram showing an example of the fluid pressure driven valve 10 according to the embodiment of the present invention. As shown in Fig. 3, the solenoid valve 50 includes, as an example of an electrical configuration, a control unit 540 that controls the solenoid valve 50, a communication unit 550 for communicating with the external device 14, and a power supply circuit unit 560 that is connected to the external power supply 15, in addition to the solenoid unit 520 and the sensor group 530 described above.

[0044] In addition to the first pressure sensor 531, second pressure sensor 532, and main valve opening sensor 533 described above, the sensor group 530 includes a voltage sensor 534 that measures the voltage supplied to the solenoid section 520, a current / resistance sensor 535 that measures the current value when current is applied to the solenoid section 520 and the resistance value when current is not applied, a temperature sensor 536 that measures the internal temperature of the accommodating section 500, and a magnetic sensor 537 that measures the strength of the magnetic field generated by the solenoid section 520.

[0045] The sensor group 530 also includes an operation time meter (timer) 538 that measures at least one of the total time that electricity is supplied to the solenoid section 520 and the current time of electricity supply as the operation time of the fluid pressure driven valve 10 as a sensor group that acquires information regarding the operation history of each section, and an operation counter (counter) 539 that counts the number of times that the solenoid valve 50, the drive unit 40, and the main valve 30 are each operated.

[0046] The sensor group 530 is not limited to the above-mentioned sensors being individually provided, and a specific sensor may also function as another sensor, so that the other sensors do not have to be individually provided. For example, the magnetic sensor 537 measures the strength of the magnetic field generated by the solenoid unit 520 and calculates the current value when the current is applied to the solenoid unit 520 based on the magnetic field strength, so that the current / resistance sensor 535 does not have to be individually provided. The controller 541 may incorporate the sensor function or realize part of the sensor function. For example, the controller 541 may incorporate an operating hour meter 538 and an operation counter 539, so that the operating hour meter 538 and the operation counter 539 do not have to be individually provided.

[0047] The control unit 540, the communication unit 550, and the power supply circuit unit 560 are configured, for example, by a general-purpose or dedicated computer (see FIG. 5 described later).

[0048] The control unit 540 processes information indicating the physical quantities and state quantities of each part of the fluid pressure driven valve 10 measured by the sensor group 530, and is equipped with a controller 541 that controls each part of the fluid pressure driven valve 10, and a valve test switch 542 that controls the electrified state of the solenoid unit 520 and opens and closes the main valve 30 during test operation.

[0049] The controller 541 incorporates, for example, a state determination device 70, and includes a function for realizing the state determination device 70. Note that all or a part of the configuration of the state determination device 70 may be realized by other equipment, for example, the external device 14 or another device (for example, the information processing device 6) connected to the fluid pressure driven valve 10.

[0050] The valve test switch 542 receives a command from the controller 541 when a predetermined test operation condition is satisfied, and executes a stroke test of the fluid pressure driven valve 10 as a test operation in which a predetermined opening and closing operation is performed.

[0051] The stroke test is performed, for example, by either a full stroke test or a partial stroke test. The full stroke test is performed by switching the main valve 30 from a conducting state to a non-conducting state in a fully open state to operate it to a fully closed state, and by switching it from a non-conducting state to a conducting state in the fully closed state to return it to the fully open state. The partial stroke test is performed by switching the main valve 30 from a conducting state to a non-conducting state in a fully open state to partially close it to a predetermined opening degree without operating the main valve 30 to a fully closed state (i.e., without stopping the equipment), and by switching it from a non-conducting state to a conducting state in the partially closed state to return it to the fully open state.

[0052] The test operation conditions may be, for example, an execution time based on an execution frequency (e.g., once a year) set by an administrator, a specific specified date and time, or a request from an external device 14. When an execution command from the solenoid valve 50 is received, or when a test execution button (not shown) provided on the solenoid valve 50 is operated by an administrator, it is determined that the test operation conditions are met and a test operation (stroke test) is executed.

[0053] The sensor group 530 of the fluid pressure driven valve 10 constitutes the physical quantity measuring device 2 shown in FIG. 1. Examples of physical quantities to be measured by the physical quantity measuring device 2 include pressure, valve opening, voltage, current, and temperature. The physical quantity measuring device 2 is composed of, for example, a first pressure sensor 531, a second pressure sensor 532, a main valve opening sensor 533, a voltage sensor 534, a current / resistance sensor 535, a temperature sensor 536, and a magnetic sensor 537, which are shown in the sensor group 530. Note that the physical quantity to be measured is not limited to the above example, and may be, for example, a physical quantity such as acceleration (vibration), speed, displacement, environmental sound, and load. In that case, a physical quantity measuring device 2 such as an acceleration sensor, a speed sensor, a displacement sensor, a sound sensor, or a load sensor is used. The physical quantity measuring device 2 may include a plurality of sensors to measure a plurality of physical quantities. The physical quantity measuring device 2 processes physical quantity information in which an analog signal indicating the measured physical quantity is converted into a digital signal. The processed physical quantity information is used by the data management device 4.

[0054] (Data management device (cloud)) 4 is a schematic block diagram showing an example of a data management device 4 according to an embodiment of the present invention. The data management device 4 includes, as its main components, a management control unit 41, a management storage unit 42, a management communication unit 43, a management input unit 44, and a management output unit 45.

[0055] The management control unit 41 functions as a management processing unit 41a by executing, for example, a data management program 42a stored in the management storage unit 42. The management communication unit 43 functions as a communication interface for transmitting and receiving various data between, for example, the physical quantity measuring device 2, the mobile terminal device 3, and the device manager terminal device 7 via the network 8. The management storage unit 42 stores various data, various programs (such as the data management program 42a) and data (such as the management setting information 42b) used in the operation of the data management device 4. The management setting information 42b is various setting parameters referenced by the management control unit 41 when the data management device 4 operates.

[0067] (Various information) Fig. 6 is a diagram showing an example of a data format of management information created by the data management device 4 according to the present embodiment. Fig. 7 is a diagram showing an example of a device identification number according to the present embodiment. Fig. 8 is a diagram showing an example of impression information according to the present embodiment.

[0068] The management information created by the data management device 4 of this embodiment is associated with, for example, an equipment identification number, an input time, impression information, physical quantity information, etc., as shown in FIG. 6. That is, the management information is associated with the impression information input by the maintenance worker M and the physical quantity information at the input time when the impression information is input, etc., for the fluid pressure driven valve 10 having the equipment identification number specified by the equipment identification information. Note that FIG. 7 illustrates a case in which the management information for the fluid pressure driven valve 10 having the equipment identification number "MA100", the fluid pressure driven valve 10 having the equipment identification number "MA200", and the fluid pressure driven valve 10 having the equipment identification number "MA300" are managed in three table formats, but the management information for the other fluid pressure driven valves 10 is created in the same manner. Note that the data format is not limited to the table format and may be changed as appropriate. In addition, the management information may be associated with, for example, terminal location information acquired as the equipment identification information, or a maintenance worker identification number uniquely assigned to the maintenance worker M who inputs the impression information.

[0069] 7, the device identification number is an ID number or the like that is uniquely assigned to each fluid pressure driven valve 10 or each component of the fluid pressure driven valve 10. The device identification number is identified directly or indirectly based on the device identification information.

[0070] The input time is the time when the maintenance worker M inputs the impression information. The input time is acquired from a clock or the like built into the mobile terminal device 3, for example.

[0071] The impression information is information input by the maintenance worker M as shown in Fig. 8, and is, for example, information such as "no abnormality", "abnormality", "abnormal sound", "something is wrong", etc. The impression information is voice data uttered by the maintenance worker M, character data converted from the voice data, character data uttered by the maintenance worker M, etc. These are input character data, selected data selected by the maintenance worker M from a set of standard sentences or options, biometric data such as the amount of sweating or heart rate of the maintenance worker M, character data converted from the biometric data, etc. The subjective information may be one of these, or any combination of these.

[0072] The physical quantity information is, for example, measurement data obtained by measuring various physical quantities by the sensor group 530 of the fluid pressure driven valve 10 to be measured. The physical quantity information may be measurement data measured by all sensors of the sensor group 530, or may be measurement data measured by a specific sensor (which may be one or more) selected from the sensor group 530. In this case, the specific sensor may be selected in advance by the maintenance manager A, or may be selected according to the content of the impression information. For example, if the impression information includes content related to "abnormal sound", an acceleration sensor or a sound sensor may be selected. The physical quantity information may be measurement data obtained by measuring various physical quantities during a predetermined period including the input time. In this case, the predetermined period including the input time may be a period between a pre-input time before the input time and the input time, a period between the input time and a post-input time after the input time, or a period between the pre-input time and the post-input time. The predetermined period may be determined in advance by the maintenance manager A, or may be determined according to the content of the impression information. For example, when the impression information includes content related to an "abnormal sound," a period necessary for analyzing the abnormal sound may be determined.

[0073] (Management daily report) FIG. 9 is a diagram showing an example of a daily management report created from management information that can be acquired by the data management system 1 according to this embodiment.

[0074] The data management device 4 of this embodiment uses the above-mentioned management information to create a management daily report with a template predetermined for each device manager U. For example, as shown in Fig. 9, the management daily report is created by including physical quantity information acquired from the physical quantity measuring device 2, impression information and input time acquired from the mobile terminal device 3, and a device identification number indicating a device or a component of a device identified based on device identification information acquired from the mobile terminal device 3. The device manager U can view the management daily report created by the data management device 4 on an app, browser, or the like installed in the device manager terminal device 7. In addition, the device manager U can download the management daily report created by the data management device 4 in a file format such as PDF.

[0075] In the daily management report shown in Figure 9, when maintenance worker M inspected at 9:00, it was judged that there was "no abnormality" and it was determined that the fluid pressure driven valve 10 was operating normally. Also, when maintenance worker M inspected at 13:00, it was judged that there was "something unusual" and it was determined that there was some kind of abnormality with the fluid pressure driven valve 10. When maintenance worker M inspected at 17:00, it was judged that there was "something abnormal" and it was determined that there was some kind of abnormality with the fluid pressure driven valve 10.

[0076] In this way, the data management device 4 acquires physical quantity information obtained by measuring the physical quantities of the fluid-pressure driven valve 10 that is the measurement target, impression information indicating the impression of the person inputting the information about the fluid-pressure driven valve 10, the input time when the impression information was input, and equipment identification information for identifying the fluid-pressure driven valve 10 as the input target of the impression information, and creates management information for the fluid-pressure driven valve 10 that associates the physical quantity information of the fluid-pressure driven valve 10 that is the measurement target and is identified based on the equipment identification information with the impression information acquired together with the equipment identification information and the input time, so that a report can be made that associates the state of the equipment with the impression of the maintenance worker M.

[0077] Furthermore, the data management device 4 creates a daily management report based on a template predetermined for each device administrator U from the management information, so that a daily management report that is easy for each device administrator U to view and use can be created.

[0078] (Data Management Method of the First Embodiment) 10 is a flowchart showing an example of a data management method executed by the data management system 1 according to the first embodiment. The flowchart of this embodiment is executed by the physical quantity measuring device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, etc.

[0079] In the data management method of the first embodiment, first, in step S311, the mobile terminal device 3 acquires impression information from the maintenance worker M. Then, the mobile terminal device 3 acquires an input time indicating the current time, and terminal location information identifying the location of the mobile terminal device 3 (maintenance worker M) at that time as device identification information.

[0080] Next, in step S312, the mobile terminal device 3 uploads (transmits) the impression information, the input time of the impression information, and the terminal location information as device identification information to the data management device 4 (cloud).

[0081] Next, in step S411, the data management device 4 receives (acquires) the impression information, the input time, and the terminal location information. Then, the data management device 4 compares the registered location information of the fluid pressure driven valve 10 registered in advance in the management setting information 42b (see FIG. 4) with the terminal location information received from the mobile terminal device 3, and specifies the device identification number of the fluid pressure driven valve 10 having registered location information closest to the terminal location information as the input target of the impression information. For example, if the registered location information closest to the terminal location information received from the mobile terminal device 3 is "Aa10", the device identification number "MA100" corresponding to the registered location information "Aa10" is specified as the fluid pressure driven valve 10 as the input target of the impression information.

[0082] Next, in step S412, the data management device 4 requests the physical quantity measuring device 2 provided in the fluid pressure driven valve 10 identified by the device identification number specified in step S411 to transmit physical quantity information. Next, in step S211, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information in response to the request from the data management device 4.

[0083] Next, in step S413, the data management device 4 receives (acquires) physical quantity information of the fluid pressure driven valve 10 as the measurement target, which is indicated by the device identification number specified based on the terminal location information. Then, in step S414, the data management device 4 creates management information that associates the physical quantity information, the device identification number specified based on the terminal location information, and the impression information and input time received together with the device identification information.

[0084] Next, in step S415, the data management device 4 creates a daily management report based on a template predetermined for each equipment manager U, from the management information created in step 414. At this time, a template for the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information is used as the template. Then, the data management device 4 transmits the daily management report to the equipment manager terminal device 7 used by the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information. Next, in step S511, the equipment manager terminal device 7 receives the daily management report and displays it, for example, on a display screen.

[0085] In this way, according to the data management method of this embodiment, management information for the fluid-pressure driven valve 10 is created which associates physical quantity information of the fluid-pressure driven valve 10 identified based on the terminal location information with the impression information and input time acquired together with the terminal location information, so that a report can be made which associates the state of the equipment with the impression of the maintenance worker M.

[0086] (Data Management Method of the Second Embodiment) 11 is a flowchart showing an example of a data management method executed by the data management system 1 according to the second embodiment. The flowchart of this embodiment is executed by the physical quantity measuring device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, etc.

[0087] In the data management method of the second embodiment, first, in step S321, the mobile terminal device 3 acquires impression information from the maintenance worker M. Then, the mobile terminal device 3 acquires an input time indicating the current time and, as device identification information, a device identification number indicating the fluid pressure driven valve 10 to which the impression information at that time is to be input.

[0088] Next, in step S322, the mobile terminal device 3 uploads (transmits) the impression information, the input time of the impression information, and the device identification number as device specification information to the data management device 4 (cloud).

[0089] Next, in step S421, the data management device 4 receives (acquires) the impression information, the input time, and the device identification number.

[0090] Next, in step S422, the data management device 4 requests the physical quantity measuring device 2 provided in the fluid pressure driven valve 10 indicated by the device identification number received in step S421 to transmit physical quantity information. Next, in step S221, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information in response to the request from the data management device 4.

[0091] Next, in step S423, the data management device 4 receives (acquires) physical quantity information of the fluid pressure driven valve 10 indicated by the device identification number as the measurement target. Then, in step S424, the data management device 4 creates management information that associates the physical quantity information, the device identification number, and the impression information and input time received together with the device identification number.

[0092] Next, in step S425, the data management device 4 creates a daily management report based on a template predetermined for each equipment manager U, from the management information created in step 424. At this time, a template for the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information is used as the template. Then, the data management device 4 transmits the daily management report to the equipment manager terminal device 7 used by the equipment manager U of the fluid pressure driven valve 10 that is the target of input of impression information. Next, in step S521, the equipment manager terminal device 7 receives the daily management report and displays it, for example, on a display screen.

[0093] In this way, according to the data management method of this embodiment, management information is created that associates physical quantity information of the fluid pressure driven valve 10 identified based on the equipment identification number as the measurement target with the impression information and input time acquired together with the equipment identification number, so that a report can be made that associates the equipment status with the impression of maintenance worker M.

[0094] (Annotation for Machine Learning) FIG. 12 is a diagram showing an example in which management information created by the data management system 1 according to this embodiment is used for annotation for machine learning.

[0095] The physical quantity information and the impression information associated by the data management system 1 may be used for annotation for machine learning. The data management system 1 of this embodiment creates, for example, physical quantity information to which a normal label is assigned and physical quantity information to which an abnormal label is assigned based on the impression information associated with the physical quantity information, thereby creating a learning data set for a classification problem in supervised learning. Note that instead of assigning two-class labels, a normal label and an abnormal label, and classifying the data, it is also possible to assign multiple classes of labels, three or more classes, and classify the data. That is, in the annotation using management information, by preparing labels for each class according to the contents of the opinion information, it is possible to create a learning dataset for any classification problem.

[0096] When creating a learning dataset, it is preferable that the physical quantity information is measurement data obtained by measuring the physical quantity of the fluid pressure driven valve 10 or its components during a predetermined period including the input time, and the impression information includes information that represents the state of the fluid pressure driven valve 10 or its components. In this case, the learning dataset used for machine learning is created by linking and classifying the physical quantity information with a label based on the impression information associated with the physical quantity information. In this way, linking the physical quantity information, for which the period for measuring the physical quantity is specified, with the label based on the impression information is effective for annotation in a learning model for a classification problem, and the learning dataset can be easily created.

[0097] For example, as shown in Fig. 8, the impression information is roughly divided into "normal" and "abnormal". The data management device 4 creates data in which the physical quantity information is labeled with "normal" or "abnormal" for each event. Machine learning may be performed by the machine learning device 5 of the data management system 1 according to this embodiment or an external machine learning device using the labeled data. The machine learning method and the configuration of the learning model may be appropriately selected.

[0098] The label "abnormal" may be further divided into "abnormal 1" and "abnormal 2", etc. For example, "abnormal 1" may be a stage where an abnormality is likely, such as "something feels strange" or "something is wrong", and "abnormal 2" may be a stage where an abnormality is definitely present, such as "abnormality" or "abnormal noise". Furthermore, abnormalities may be further divided to identify specific locations or causes, such as "cylinder abnormality" or "external air leakage".

[0099] In this way, the data management system 1 of the present embodiment creates a learning data set used for machine learning using physical quantity information and subjective information associated with the physical quantity information, and therefore enables efficient learning of a supervised learning model for condition diagnosis (e.g., abnormality diagnosis). In other words, a learning model reflecting the know-how of an experienced maintenance worker M can be efficiently created.

[0100] (Other embodiments) The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention. All such modifications are included in the technical concept of the present invention.

[0101] In the above embodiment, the data management device 4, the machine learning device 5, and the information processing device 6 have been described as being configured as separate devices. In contrast, the data management device 4, the machine learning device 5, and the information processing device 6 may be configured as a single device or two devices in any combination. Furthermore, the information processing device 6 may be incorporated into a device (for example, the controller 541 of the fluid pressure driven valve 10).

[0102] In the above embodiment, the data management device 4 has been described as requesting physical quantity information from the physical quantity measuring device 2 that measures the physical quantity of the device or component that is the subject of input of impression information in steps S412 and S422, and acquiring the physical quantity information in steps S413 and S423. In contrast, the physical quantity measuring device 2 may periodically transmit physical quantity information to the data management device 4 regardless of the above request, and the data management device 4 may accumulate the physical quantity information in the management storage unit 42 by device or component, so that the data management device 4 may acquire physical quantity information in which the physical quantity of the device or component that is the subject of input of impression information is measured from the management storage unit 42. In this case, the data management device 4 may store a predetermined time including the input time as the physical quantity information. Alternatively, measurement data measured over a fixed period of time may be acquired. [Explanation of symbols]
