Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the following, the range necessary for the description for achieving the object of the present invention is schematically shown, and mainly the range necessary for the description of the relevant part of the present invention will be described, and the parts where the description is omitted shall be based on known techniques.

[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 a device. The main components of the data management system 1 include a fluid pressure driven valve 10 to be measured, a physical quantity measuring device 2 for measuring the physical quantities of the fluid pressure driven valve 10, a portable terminal device 3 used by a maintenance staff M (such as an inspector / repair worker of the fluid pressure driven valve 10) as an input person, a data management device 4 configured to be communicable with the fluid pressure driven valve 10 and the portable terminal device 3, etc., and used by a maintenance manager A (such as a manager of inspectors / repair workers), and a device manager terminal device 7 configured to be communicable with the data management device 4, etc., and used by a device manager U (such as a manager / owner of the fluid pressure driven valve 10) as a reporting target person.

[0012] In this embodiment, the fluid pressure driven valve 10 is described as an example of a device, but the device is not limited to the fluid pressure driven valve 10, and other valves such as a breathing valve, a rotating machine, a tank, and other general devices can be used. Further, the device includes one or more components constituting 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 to be measured or the components constituting the fluid pressure driven valve 10. The physical quantity measuring device 2 may be incorporated in the fluid pressure driven valve 10 or provided as a separate device from the fluid pressure driven valve 10 to the fluid pressure driven valve 10. The physical quantity information is, for example, measurement data obtained from various sensors installed in the fluid pressure driven valve 10 or processed data obtained by processing the measurement data. At that time, the physical quantity information may be obtained by recording measurement data (hereinafter including processed data) obtained from the sensor at a predetermined sampling period or sampling frequency.

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

[0015] The data management device 4 is configured by, for example, a server-type computer or a cloud-type computer. The data management device 4 includes a management control unit 41 that creates management information by associating the physical quantity information received from the physical quantity measurement device 2, the proprioceptive information and the input time received from the portable terminal device 3, by device or by 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 proprioceptive information may be voice data, character data (text data), etc. that the maintenance staff M intuitively uttered about the fluid pressure driven valve 10. In the case of voice data, it is preferable for the portable terminal device 3 to convert the voice data into character data. Also, the proprioceptive information may be biological data such as the sweating amount or heart rate of the maintenance staff M. In the case of biological data, it is preferable for the portable terminal device 3 to convert it into character data such as "abnormal" when the sweating amount or heart rate is high and "normal" when it is low. The input time may be obtained from a clock or the like built into the portable 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, device identification numbers such as ID numbers uniquely assigned to each fluid pressure driven valve 10 or each component of the fluid pressure driven valve 10, and terminal position information for identifying the position of the portable terminal device 3.

[0018] For the device identification number, for example, it is obtained by the following method. For example, if there is a code image (such as a one-dimensional code or a two-dimensional code) or an ID tag (such as RFID) that records the device identification number, the address of the information transmission destination, etc. on the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10, the portable terminal device 3 may obtain the device identification number by a code recognition function for the code image captured by the camera of the portable terminal device 3 or a tag reading function of the ID tag. If there is a seal with the device identification number printed on the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10, the portable terminal device 3 may obtain the device identification number by a character recognition function for the seal captured by the camera of the portable terminal device 3. In addition, the portable terminal device 3 may obtain the device identification number by receiving an input operation for inputting the device identification number by the maintenance staff M. For the terminal position information, the portable terminal device 3 may obtain the terminal position information by a position detection function such as the GPS, Wi-Fi, beacon, inertial navigation sensor, geomagnetic sensor, etc. of the portable terminal device 3.

[0019] When the device specific information is the device identification number, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is directly specified by the device identification number. When the device specific information is the terminal position information, the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 is indirectly specified by the terminal position information. Specifically, the maintenance manager A registers the registered position information of the fluid pressure driven valve 10 in the data management device 4 in advance. The portable terminal device 3 transmits the terminal position information as the device specific information to the data management device 4 together with the sensed information and the input time. The data management device 4 collates the terminal position information received from the portable terminal device 3 with the registered position information of the fluid pressure driven valve 10 registered in advance, and thereby specifies the fluid pressure driven valve 10 or a component of the fluid pressure driven valve 10 having the registered position information closest to the terminal position information. In any case, the data management device 4 , among the plurality of fluid pressure driven valves 10 or the components of the plurality of fluid pressure driven valves 10, based on the device identification information received from the portable terminal device 3, identify the fluid pressure driven valve 10 or the component of the fluid pressure driven valve 10 that is the input target of the emotional information, and associate the physical quantity information received from the physical quantity measurement device 2 with the emotional information and input time received from the portable terminal device 3 to create management information.

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

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

[0022] Note that 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 fluid pressure driven valve 10 using the learning model learned by the machine learning device 5.

[0023] The machine learning device 5 operates as the main body in the learning phase of machine learning. For example, it acquires a learning dataset for machine learning created by the data management device 4 using physical quantity information and emotional information associated with the physical quantity information, and generates a learning model used by the information processing device 6 through machine learning. 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 main body in the inference phase of machine learning. Using the learning model generated by the machine learning device 5, it predicts the state of the fluid pressure driven valve 10 from the physical quantity information during operation, and transmits the state information of the fluid pressure driven valve 10, which is the result of the prediction, 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 by, for example, a general-purpose or dedicated computer (see FIG. 5 described later), and is configured to be able to mutually transmit and receive various data via the network 8. Note that the number of each of the devices 3 to 7 is not limited to the example in FIG. 1, and may be one or a plurality.

[0026] (Fluid pressure driven valve 10) FIG. 2 is a schematic configuration diagram showing an example of the 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 method. During normal operation, by supplying air A (air supply) from the air supply source 13 to the drive device 40 via the solenoid valve 50, the main valve 30 is opened. During an emergency stop or test operation, by discharging air A (exhaust) from the drive device 40 via the solenoid valve 50, the main valve 30 is closed. Note that the fluid pressure driven valve 10 may employ an airless open method. In that case, it is closed by supplying air A to the drive device 40, and the main valve 30 is opened by discharging air A from the drive device 40.

[0028] In the fluid pressure driven valve 10, as a flow path for air A, a first air pipe 130 connecting between the air supply source 13 and the solenoid valve 50 and a second air pipe 131 connecting between the solenoid valve 50 and the drive device 40 are provided. Note that the drive fluid is not limited to the above-mentioned air A, and may be other gases or liquids (for example, oil).

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

[0030] The external device 14 is a device for transmitting and receiving 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 a storage medium for data storage, etc. Note that any communication standard may be adopted for the communication between the external device 14 and the solenoid valve 50, and wireless communication may also be used. In the present embodiment, the external device 14 corresponds to a data management device 4 or the like.

[0031] A ball valve is adopted for the main valve 30 shown in FIG. 2. As its specific configuration, the main valve 30 includes a valve box 32 disposed in the middle of a pipe 11 and a ball-shaped valve body 31 rotatably provided in the valve box 32. A valve shaft 12 is connected to the upper part of the valve body 31. As the valve shaft 12 rotates from 0 degrees to 90 degrees, the valve body 31 rotates in the valve box 32, and the fully open state (the state shown in FIG. 2) and the fully closed state of the main valve 30 are switched. Note that the valve used as the main valve 30 is not limited to a ball valve, and for example, a butterfly valve or other on-off valves may be used.

[0032] A single-acting air cylinder mechanism is adopted for the driving device 40 shown in FIG. 2. As its specific configuration, the driving device 40 includes a cylinder 400 having a spring chamber 470 and a cylinder chamber 480, a pair of pistons 420A and 420B reciprocally linearly movable in the cylinder 400 and connected via a piston rod 410, a coil spring 430 provided in the spring chamber 470 on the first piston 420A side, an air supply and 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 and the piston rod 410 arranged to penetrate the cylinder 400 in the radial direction are orthogonal to each other. Note that the driving device 40 is not limited to a single-acting type, and for example, it may be configured in other forms such as a double-acting type.

[0033] The first piston 420A is biased in a direction to close the main valve 30 by a coil spring 430. 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 (intake air) supplied from the air supply and exhaust 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 a rotational motion and transmits it to the valve shaft 12.

[0034] The solenoid valve 50 shown in FIG. 2 employs a three-way solenoid valve of the 2-position normally closed type (open when energized, closed when de-energized). As its specific configuration, the solenoid valve 50 includes, inside the housing portion 500, a spool portion 510 that switches the flow path through which air A flows, a solenoid portion 520 that displaces the spool portion 510 according to the energized state (when energized or de-energized), and a sensor group 530 that measures the physical quantities and state quantities of each part of the solenoid valve 50. Note that the solenoid valve 50 is not limited to a 2-position normally closed type three-way solenoid valve, and may be a 3-position, a normally open type, a four-way solenoid valve, etc., and may be configured in various forms based on any combination.

[0035] The housing portion 500 functions as the housing of the indoor type or explosion-proof type solenoid valve 50. The housing portion 500 includes a shaft insertion port 501 into which the valve shaft 12 (the 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 includes an input port 511 connected to the air supply source 13 via the first air pipe 130, an output port 512 connected to the drive device 40 via the second air pipe 131, and an exhaust port 513 that discharges the exhaust from the drive device 40.

[0037] When energized, the solenoid portion 520 displaces the spool portion 510 so as to communicate between the input port 511 and the output port 512, and when de-energized, displaces the spool portion 510 so as to communicate between the output port 512 and the exhaust port 513.

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

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

[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 respectively connected to the second shaft 12b and the third shaft 12c via a coupling, a connector, etc., and the first shaft 12a, the second shaft 12b, and the third shaft 12c are arranged coaxially. The first shaft 12a is arranged so as to penetrate the drive device 40 and is driven by the drive device 40. The second shaft 12b is connected to the first shaft 12a and is also connected to the main valve 30. The third shaft 12c is connected to the first shaft 12a and is inserted into the housing portion 500 of the solenoid valve 50 and is pivotally supported. The valve shaft 12 performs a rotational movement as a whole in synchronization with the driving of the first shaft 12a by the drive device 40.

[0041] In the fluid pressure driven valve 10 having the above configuration, when the solenoid valve 50 is energized, the air A (supply air) from the air supply source 13 flows in the order of the first air pipe 130, the input port 511, the output port 512, and the second air pipe 131, and is supplied to the air supply and discharge port 440, whereby the second piston 420B is pressed and the coil spring 430 is compressed. Then, as the piston rod 410 moves according to the compression of the coil spring 430, the first shaft 12a (valve shaft 12) is rotated via the piston rod 410 and the transmission mechanism 450, and the valve body 31 rotates in the valve box 32, and the main valve 30 is operated to the fully open state.

[0042] On the other hand, when the solenoid valve 50 is de-energized, the air A (exhaust air) in the cylinder 400 flows in the order of the second air pipe 131, the output port 512, and the exhaust port 513 from the air supply and discharge port 440 and is discharged to the outside air, whereby the pressing force of the second piston 420B decreases and the coil spring 430 is restored from the compressed state. Then, as the piston rod 410 moves according to the restoration of the coil spring 430, the first shaft 12a (valve shaft 12) is rotated via the transmission mechanism 450, and the valve body 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 an embodiment of the present invention. As shown in FIG. 3, the solenoid valve 50, as an electrical configuration example, in addition to the solenoid unit 520 and the sensor group 530 described above, includes a control unit 540 for controlling the solenoid valve 50, a communication unit 550 for communicating with the external device 14, and a power supply circuit unit 560 connected to the external power supply 15.

[0044] The sensor group 530 includes, in addition to the first pressure sensor 531, the second pressure sensor 532, and the main valve opening sensor 533 described above, a voltage sensor 534 for measuring the supply voltage to the solenoid unit 520, a current / resistance sensor 535 for measuring the current value during energization and the resistance value during non-energization in the solenoid unit 520, a temperature sensor 536 for measuring the internal temperature of the housing unit 500, and a magnetic sensor 537 for measuring the strength of the magnetic field generated by the solenoid unit 520.

[0045] In addition, the sensor group 530 includes an operation time meter (timer) 538 that measures at least one of the total energization time for the solenoid unit 520 and the current continuous energization time as the operation time of each part, as a sensor group that acquires information regarding the operation history of each part, and an operation counter (counter) 539 that counts the number of operations of each of the solenoid valve 50, the drive device 40, and the main valve 30.

[0046] Note that the sensor group 530 is not limited to the case where sensors are individually provided as described above. Even if other sensors are not individually provided, a specific sensor may also serve as the functions of other sensors. For example, the magnetic sensor 537 measures the strength of the magnetic field generated by the solenoid unit 520, and obtains the current value during energization in the solenoid unit 520 based on the strength of the magnetic field, so that the current / resistance sensor 535 does not have to be individually provided. Further, the controller 541 may incorporate the functions of the sensors or may implement a part of the functions of the sensors. For example, if the controller 541 incorporates the operation time meter 538 and the operation counter 539, the operation time 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 composed of, for example, a general-purpose or dedicated computer (see FIG. 5 described later).

[0048] The control unit 540 includes a controller 541 that 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 controls each part of the fluid pressure driven valve 10, and a valve test switch 542 that controls the energization state of the solenoid unit 520 and performs the opening / closing operation of the main valve 30 during the test operation.

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

[0050] When the predetermined test operation conditions are satisfied, the valve test switch 542 receives a command from the controller 541 and executes a stroke test of the fluid pressure driven valve 10 as a test operation for performing a predetermined opening / closing operation.

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

[0052] Note that as the test operation conditions, for example, the execution timing based on the execution frequency (e.g., once a year) specified as a set value by the administrator, or when a specific specified date and time arrives, or when receiving an execution command from the external device 14, or when the test execution button (not shown) provided on the solenoid valve 50 is operated by the administrator, the test operation (stroke test) may be executed so as to satisfy the test operation conditions.

[0053] The sensor group 530 of the fluid pressure driven valve 10 constitutes the physical quantity measuring device 2 shown in FIG. 1. The physical quantity to be measured by the physical quantity measuring device 2 is, for example, pressure, valve opening degree, voltage, current, temperature, etc. 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 degree sensor 533, a voltage sensor 534, a current / resistance sensor 535, a temperature sensor 536, a magnetic sensor 537, etc. shown in the sensor group 530. Note that the physical quantity to be measured is not limited to the above examples, and may be, for example, physical quantities such as acceleration (vibration), speed, displacement, ambient sound, load, etc. In that case, a physical quantity measuring device 2 such as an acceleration sensor, a speed sensor, a displacement sensor, a sound sensor, a load sensor, etc. is used. Also, the physical quantity measuring device 2 may include a plurality of sensors in order to measure a plurality of physical quantities respectively. 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)) FIG. 4 is a schematic block diagram showing an example of the 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, for example, by executing 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 to and from, for example, the physical quantity measurement device 2, the mobile terminal device 3, and the device administrator 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 management setting information 42b) used in the operation of the data management device 4. The management setting information 42b is various setting parameters referred to by the management control unit 41 when the data management device 4 operates. As shown in FIG. 4, the management setting information 42b includes, for example, registration position information of devices or components and device identification numbers corresponding to the registration position information for each device or component. Note that the registration position information may be latitude and longitude or a predetermined unique data format. The management input unit 44 and the management output unit 45 function as a user interface by receiving input operations from the maintenance administrator A and outputting various information via a display screen or voice.

[0056] Based on the device identification information acquired from the mobile terminal device 3, the management processing unit 41a creates management information by associating the physical quantity information acquired from the physical quantity measurement device 2 with the emotional information and input time acquired from the mobile terminal device 3. For example, when the physical quantity measurement device 2 and the mobile terminal device 3 start communication with the management processing unit 41a via the management communication unit 43 and the management processing unit 41a receives emotional information, input time, device identification information, etc. from the mobile terminal device 3, the management processing unit 41a executes a management process for creating management information.

[0057] As a management process, the management processing unit 41a identifies a device or component that is the input target of the proprioceptive information based on the device identification information. The management processing unit 41a creates management information by associating the physical quantity information of the device or component to be measured based on the device identification information with the proprioceptive information and the input time acquired together with the device identification information. At this time, the management processing unit 41a may create management information by associating the physical quantity information obtained by measuring the physical quantity for a predetermined period including the input time acquired together with the device identification information, with the proprioceptive information acquired together with the device identification information, with the device or component identified based on the device identification information as the measurement target.

[0058] The management information created by the management processing unit 41a is transmitted to the device manager terminal device 7. Note that the management information may be stored in the management storage unit 42 and made referable by an application, a browser, or the like. Further, the management control unit 41 may analyze the management information to perform a detailed diagnosis.

The input device 916 and the display device 918 may be integrally configured like a touch panel display. The storage device 920 is composed of, for example, an HDD, an SSD, etc. and functions as a storage unit. The storage device 920 stores various data necessary for the execution of the operating system and the program 930.

[0066] The computer 900 is constituted by, for example, a stationary computer or a portable computer, and is an electronic device in any form. The computer 900 may be a client-type computer, a server-type computer, a cloud-type computer, or may be an embedded computer called, for example, a control panel, a controller (including a microcomputer, a programmable logic controller, a sequencer), etc. The computer 900 may be applied to other devices such as the portable terminal device 3, the machine learning device 5, the information processing device 6, and the device manager terminal device 7 other than the data management device 4.

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

[0068] The management information created by the data management device 4 of the present embodiment is associated with, for example, as shown in FIG. 6, a device identification number, an input time, sensed information, physical quantity information, etc. That is, the management information is associated with the sensed information input by the maintenance staff M and the physical quantity information at the input time when the sensed information was input, for the fluid pressure driven valve 10 with the device identification number specified by the device specific information. Note that FIG. 7 shows a case where the management information for the fluid pressure driven valve 10 with the device identification number "MA100", the fluid pressure driven valve 10 with the device identification number "MA200", and the fluid pressure driven valve 10 with the device identification number "MA300" is managed in three table formats, but the management information for other fluid pressure driven valves 10 is created in the same way. Note that the data format is not limited to the table format and may be changed as appropriate. Further, the management information may be associated with, for example, the terminal position information acquired as the device specific information and the maintenance staff identification number uniquely assigned to the maintenance staff M who input the sensed information.

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

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

[0071] As shown in FIG. 8, the sensed information is information input from the maintenance staff M, and is, for example, information such as "no abnormality", "abnormality", "abnormal noise", "something strange", etc. The sensed information is voice data uttered by the maintenance staff M, character data converted from the voice data, character data input by the maintenance staff M, selection data selected by the maintenance staff M from pre-defined sentences or options, biological data such as the sweating amount and heart rate of the maintenance staff M, character data converted from the biological data, etc. Note that the sensed information may be any one of these, or may be an arbitrary combination of these.

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

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

[0074] The data management device 4 of the present embodiment creates a management daily report using the above-described management information in a template predetermined for each equipment manager U. The management daily report is created, for example, as shown in FIG. 9, by including the physical quantity information obtained from the physical quantity measuring device 2, the feeling information and the input time obtained from the portable terminal device 3, and the equipment identification number indicating the equipment or the component of the equipment specified based on the equipment specific information obtained from the portable terminal device 3. The equipment manager U can view the management daily report created by the data management device 4 using an application or a browser installed on the equipment manager terminal device 7. Further, the equipment 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 management daily report shown in FIG. 9, it can be seen that when the maintenance staff M inspected at 9:00, it was determined that there was "no abnormality", and it was judged that the fluid pressure driven valve 10 was operating normally. Also, when the maintenance staff M inspected at 13:00, it was determined that there was "a sense of discomfort", and it was judged that there was some sense of discomfort in the fluid pressure driven valve 10. When the maintenance staff M inspected at 17:00, it was determined that there was "abnormality", and it was judged that some abnormality was felt in the fluid pressure driven valve 10.

[0076] In this way, the data management device 4 acquires the physical quantity information obtained by measuring the physical quantity of the fluid pressure driven valve 10 to be measured, the feeling information indicating the feeling of the input person with respect to the fluid pressure driven valve 10, the input time when the feeling information was input, and the device identification information for identifying the fluid pressure driven valve 10 as the input target of the feeling information, and creates the management information of the fluid pressure driven valve 10 in which the physical quantity information with the fluid pressure driven valve 10 specified based on the device identification information as the measurement target, the feeling information and the input time acquired together with the device identification information are associated. Therefore, a report associating the state of the device with the feeling of the maintenance staff M can be made.

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

[0078] (Data management method of the first embodiment) FIG. 10 is a flowchart showing an example of a data management method executed by the data management system 1 according to the first embodiment. Note that the flowchart of the present embodiment is executed by the physical quantity measurement device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, and the like.

[0079] In the data management method of the first embodiment, first, in step S311, the mobile terminal device 3 acquires the emotional information from the security guard M. Then, the mobile terminal device 3 acquires the input time indicating the time at that moment and, as device identification information, the terminal position information that identifies the position of the mobile terminal device 3 (security guard M) at that time.

[0080] Subsequently, in step S312, the mobile terminal device 3 uploads (transmits) the emotional information, the input time of the emotional information, and the terminal position 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 emotional information, the input time, and the terminal position information. Then, the data management device 4 collates the registration position information of the fluid pressure driven valve 10 registered in advance in the management setting information 42b (see FIG. 4) with the terminal position information received from the mobile terminal device 3, and identifies the device identification number of the fluid pressure driven valve 10 having the registration position information closest to the terminal position information as the input target of the emotional information. For example, when the registration position information closest to the terminal position information received from the mobile terminal device 3 is "Aa10", the device identification number "MA100" corresponding to the registration position information "Aa10" is identified as the fluid pressure driven valve 10 that is the input target of the emotional information.

[0082] Subsequently, in step S412, 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 identified in step S411 to transmit the physical quantity information. Subsequently, in step S211, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information as a 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 for the fluid pressure drive valve 10 indicated by the device identification number specified based on the terminal position information. Subsequently, in step S414, the data management device 4 creates management information associating the physical quantity information, the device identification number specified based on the terminal position information, the proprioceptive information received together with the device identification information, and the input time.

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

[0085] Thus, according to the data management method of the present embodiment, since management information of the fluid pressure drive valve 10 associating the physical quantity information for the fluid pressure drive valve 10 specified based on the terminal position information, the proprioceptive information acquired together with the terminal position information, and the input time is created, it is possible to make a report associating the state of the device and the feelings of the maintenance staff M.

[0086] (Data management method of the second embodiment) FIG. 11 is a flowchart showing an example of a data management method executed by the data management system 1 according to the second embodiment. Note that the flowchart of the present embodiment is executed by the physical quantity measurement device 2, the mobile terminal device 3, the data management device 4, the device manager terminal device 7, and the like.

[0087] In the data management method of the second embodiment, first, in step S321, the mobile terminal device 3 acquires the emotional information from the security guard M. Then, the mobile terminal device 3 acquires the input time indicating the time at that moment and, as device identification information, the device identification number indicating the fluid pressure driven valve 10 which is the input target of the emotional information at that time.

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

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

[0090] Subsequently, 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 the physical quantity information. Subsequently, in step S221, the physical quantity measuring device 2 notifies the data management device 4 of the physical quantity information as a response to the request from the data management device 4.

[0091] Next, in step S423, the data management device 4 receives (acquires) the physical quantity information for measuring the fluid pressure driven valve 10 indicated by the device identification number. Subsequently, in step S424, the data management device 4 creates management information associating the physical quantity information, the device identification number, and the emotional information and the input time received together with the device identification number.

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

[0093] As described above, according to the data management method of the present embodiment, management information is created in which the physical quantity information for which the fluid pressure driven valve 10 specified based on the equipment identification number is the measurement target is associated with the feeling information and the input time acquired together with the equipment identification number. Therefore, it is possible to report the state of the equipment in association with the feelings of the maintenance staff M.

[0094] (Annotation for machine learning) FIG. 12 is a diagram showing an example of using the management information created by the data management system 1 according to the present embodiment for annotation for machine learning.

[0095] The physical quantity information and the feeling information associated by the data management system 1 may be used for annotation for machine learning. The data management system 1 of the present embodiment creates, for example, physical quantity information with a normal label and physical quantity information with an abnormal label based on the feeling information associated with the physical quantity information, thereby creating a learning data set for a classification problem in supervised learning. Instead of classifying by assigning two classes of labels, a normal label and an abnormal label, it may be classified by assigning multi-class labels of three or more classes. That is, in the annotation using the management information, by preparing labels for each class according to the content of the feeling information, a learning data set for an arbitrary classification problem can be created. That is, in the annotation using the management information, by preparing labels for each class according to the content of the feeling information, a learning data set for an arbitrary classification problem can be created.

[0096] When creating a learning dataset, 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 proprioceptive information preferably includes information representing the state of the fluid pressure driven valve 10 or its components. At this time, a learning dataset used for machine learning is created by associating and classifying the physical quantity information with a label based on the proprioceptive information associated with the physical quantity information. In this way, associating the physical quantity information with a specific measurement period and the label based on the proprioceptive information is effective for annotation in the learning model of the classification problem, and the learning dataset can be easily created.

[0097] For example, as shown in FIG. 8, the proprioceptive information is roughly divided into "no abnormality" and "abnormality". The data management device 4 creates data in which the physical quantity information is labeled with "no abnormality" or "abnormality" for each event. Machine learning may be executed in the machine learning device 5 of the data management system 1 according to the present embodiment or an external machine learning device using the labeled data. Note that the machine learning method and the configuration of the learning model may be appropriately selected.

[0098] Note that the label of "abnormality" may be further subdivided into "abnormality 1" and "abnormality 2". For example, "abnormality 1" may be at a stage where there seems to be an abnormality such as "uneasy feeling" or "something strange", and "abnormality 2" may be at a stage where there is definitely an abnormality such as "abnormality" or "abnormal noise". Further, the abnormality may be subdivided to specify a specific location or cause such as "cylinder abnormality" or "external air leakage".

[0099] As described above, since the data management system 1 of the present embodiment creates a learning dataset used for machine learning from the physical quantity information and the proprioceptive information associated with the physical quantity information, it is possible to efficiently learn a supervised learning model for state diagnosis (for example, abnormality diagnosis). That is, it is possible to efficiently create a learning model reflecting the know-how of the skilled maintenance worker M.

[0100] (Other embodiments) The present invention is not restricted to the above-described embodiments, and various modifications can be made and implemented without departing from the gist of the present invention. And all of them are included in the technical idea 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 by separate devices. In contrast, the data management device 4, the machine learning device 5, and the information processing device 6 may be configured by a single device or two devices in an arbitrary combination. Further, the information processing device 6 may be incorporated into a device (for example, the controller 541 of the fluid pressure drive valve 10).

[0102] In the above embodiment, in steps S412 and S422, the data management device 4 has been described as acquiring physical quantity information in steps S413 and S423 by requesting physical quantity information from the physical quantity measurement device 2 that measures the physical quantity of the device or component that is the input target of the sensed information. In contrast, the physical quantity measurement device 2 may transmit physical quantity information to the data management device 4 periodically without depending on 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. Thus, the data management device 4 may acquire, from the management storage unit 42, the physical quantity information in which the physical quantity of the device or component that is the input target of the sensed information has been measured. At that time, as the physical quantity information, the data management device 4 may acquire the measurement data measured during a predetermined period including the input time. The measurement data measured during a predetermined period may be acquired.
