Description

[Technical field]

[0001] The present invention relates to an assembly condition presentation device and an assembly condition presentation method. [Background technology]

[0002] Conventionally, there is known a fluid pressure driven valve that controls a driving fluid by a solenoid valve and opens and closes a main valve via a valve shaft driven by a drive device. For example, Patent Document 1 discloses an emergency shutoff valve device as a fluid pressure driven valve used in piping of a plant facility, which, in an emergency such as when an abnormality occurs in the facility, controls the driving fluid by a solenoid valve and closes a ball valve (main valve) via a drive device to shut off the fluid flowing through the piping. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-97539 A Summary of the Invention [Problem to be solved by the invention]

[0004] In order to improve the availability and reliability of the entire plant equipment, it is preferable that unexpected abnormalities do not occur in fluid pressure driven valves such as emergency shutoff valves used in plant equipment as shown in Patent Document 1. Therefore, in such fluid pressure driven valves, it is desirable to realize not only corrective maintenance that identifies an abnormality when it occurs, but also predictive maintenance that identifies signs of an abnormality.

[0005] Here, the fluid pressure driven valve has a main valve, a drive device, and a solenoid valve as its component parts, and each component part has multiple types of main valves, multiple types of drive devices, and multiple types of solenoid valves. In addition, the usage environment in which the fluid pressure driven valve is used is assumed to be a variety of environments because various conditions such as the type and pressure of the fluid, and the situation of the usage location are different. Therefore, when the characteristics required of the fluid pressure driven valve (e.g., lifespan, etc.) and the usage environment in which the fluid pressure driven valve is used are specified as the specifications of the fluid pressure driven valve, it is difficult to select an appropriate combination that satisfies the specifications from the countless combinations of components, and a large part of it relies on the experience (including tacit knowledge) of the designer.

[0006] The present invention has been made in consideration of the above problems, and has an object to provide an assembly condition presentation device and an assembly condition presentation method that are capable of presenting a combination of component parts that meets the specifications of a fluid-pressure-driven valve. [Means for solving the problem]

[0007] In order to achieve the above object, an assembly condition presentation device according to one aspect of the present invention comprises: 1. An assembly condition presentation device that presents assembly of a fluid pressure driven valve including a main valve used in a predetermined operating environment, a drive device that drives a valve stem connected to the main valve, and a solenoid valve that controls supply and discharge of a drive fluid to and from the drive device, a storage unit that stores a database in which characteristic reference data serving as a standard for the characteristics of the fluid pressure driven valve is registered for each combination of a plurality of types of the use environments, a plurality of types of the main valves, a plurality of types of the drive devices, and one or a plurality of types of the solenoid valves; a specification receiving unit that receives, as specifications of the newly assembled fluid-pressure driven valve, the properties required of the fluid-pressure driven valve and the usage environment in which the fluid-pressure driven valve is to be used; a candidate extraction unit that refers to the database and extracts candidates for combinations of the main valve, the drive device, and the solenoid valve that constitute the fluid pressure driven valve and satisfy the specifications; and an information presenting unit that presents the combination candidates extracted by the candidate extracting unit as the assembly conditions. Effect of the Invention

[0008] According to an assembly condition presentation device according to one aspect of the present invention, when a specification reception unit receives, as specifications for a newly assembled fluid-pressure driven valve, characteristics required for the fluid-pressure driven valve and an operating environment in which the fluid-pressure driven valve will be used, a candidate extraction unit refers to a database and extracts candidate combinations of a main valve, a drive unit, and a solenoid valve that constitute the fluid-pressure driven valve and that satisfy the specifications, and an information presentation unit presents the candidate combinations extracted by the candidate extraction unit as assembly conditions. Thus, it is possible to present combinations of components that satisfy the specifications of the fluid-pressure driven valve.

[0011] 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.

[0012] FIG. 1 is an overall configuration diagram showing an example of an assembly support system 100 for a fluid pressure driven valve 1 according to an embodiment of the present invention.

[0013] The fluid pressure driven valve 1, which is the object of support in the assembly support system 100, is, for example, The fluid pressure driven valve 1 is installed in a pipe 11 through which a control fluid such as various gases or oil flows in an actual facility such as a gas facility or an infrastructure facility. The fluid pressure driven valve 1 is used as an emergency shutoff valve for shutting off the flow in the pipe 11 during an emergency stop due to some abnormality occurring in the actual facility, for example. Note that the actual facility and uses in which the fluid pressure driven valve 1 is installed are not limited to the above examples.

[0014] The fluid pressure driven valve 1 mainly comprises a main valve 3 arranged midway through a pipe 11, a drive unit 4 that drives a valve shaft 12 connected to the main valve 3, and a solenoid valve 5 that controls the supply and discharge of driving fluid to the drive unit 4. Furthermore, if an abnormality occurs in the fluid pressure driven valve 1 itself, the function as an emergency cutoff valve as described above will be lost, so the fluid pressure driven valve 1 is provided with a condition diagnosis function for monitoring the condition of the fluid pressure driven valve 1 (for example, the presence or absence of abnormalities, remaining life, etc.) in accordance with predetermined condition diagnosis conditions.

[0015] The main valve 3, the drive unit 4, and the solenoid valve 5, which are components that make up the fluid pressure driven valve 1, are provided in a plurality of types of main valves 3 (31, 32, ..., 3 q ) and multiple types of drive units 4 (41, 42, ..., 4 r ) and multiple types of solenoid valves 5 (51, 52, ..., 5 s In addition, the operating environment 10 in which the fluid pressure driven valve 1 is used has various different conditions such as the type and pressure of the control fluid flowing through the pipe 11, the situation of the place of use (outdoors or indoors, outside temperature, humidity, etc.), and so on. Therefore, there are multiple operating environments 10 (101, 102, ..., 10 p ) are assumed. The properties of the fluid pressure-driven valve 1 are characterized according to the combination of the usage environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5. Note that the subscripts p, q, r, and s are arbitrary integers and indicate the number of types of usage environment 10, main valve 3, drive unit 4, and solenoid valve 5, respectively.

[0016] Therefore, when the properties required of the fluid pressure driven valve 1 and the usage environment 10 in which the fluid pressure driven valve 1 will be used are specified as the specifications of a newly assembled fluid pressure driven valve 1, it is necessary to select a combination of components that satisfy these specifications, that is, the type of the main valve 3, the type of the drive unit 4, and the type of the solenoid valve 5. The types are specified, for example, by the model name, type name, model number, etc.

[0017] Therefore, the assembly support system 100 for the fluid-pressure driven valve 1 generates a database 2 for presenting assembly conditions for a newly assembled fluid-pressure driven valve 1, and uses the database 2 to present candidate combinations of a main valve 3, a drive unit 4, and a solenoid valve 5 that satisfy the specifications of the fluid-pressure driven valve 1, thereby functioning as a system for supporting the assembly of the fluid-pressure driven valve 1.

[0018] Furthermore, when a specific combination is selected from the candidate combinations presented as described above and the fluid-pressure-driven valve 1 is newly assembled according to the specific combination, the fluid-pressure-driven valve 1 is subjected to an assembly inspection based on a plurality of inspection items such as appearance, structure, dimensions, pressure resistance, leakage, operating state, etc. Criteria for judging whether the assembly inspection has passed or failed are set for each inspection item.

[0019] In particular, for the inspection items related to the operating state, judgment criterion data serving as a reference for the operating state when a predetermined opening and closing operation is performed on the fluid pressure driven valve 1 during assembly inspection, and property reference data serving as a reference for the properties derived from the operating state when an opening and closing operation is performed on the fluid pressure driven valve 1 after assembly inspection are set. Then, when a newly assembled fluid pressure driven valve 1 is to be judged in assembly inspection, the operating state when an opening and closing operation is performed on the fluid pressure driven valve 1 is measured as judgment object data, and assembly inspection is performed based on the judgment criterion data, property reference data, and judgment object data. Details of the property reference data will be described later.

[0020] For this reason, the assembly support system 100 for the fluid pressure driven valve 1 generates a database 2 for setting judgment criteria data and property criteria data that serve as standards for assembly inspection, and The system also functions as a system for supporting assembly inspection of the fluid pressure driven valve 1 using the base 2.

[0021] The assembly support system 100 mainly comprises a database generating device 6 that generates a database 2 used to determine the properties of the fluid-pressure-driven valve 1, and an assembly condition presenting device 7 that uses the database 2 to determine the properties of the fluid-pressure-driven valve 1 during assembly inspection.

[0022] The database generating device 6 has a database 2 in which state reference data and property reference data can be registered for each combination of a usage environment 10, a main valve 3, a drive device 4, and a solenoid valve 5, and provides the state reference data and property reference data registered in the database 2 to the assembly condition presentation device 7.

[0023] When the assembly condition presentation device 7 receives the specifications of the fluid pressure driven valve 1, it refers to the database 2 provided by the database generation device 6 and presents candidate combinations of the main valve 3, drive device 4, and solenoid valve 5 that satisfy the specifications.

[0024] Furthermore, when the fluid-pressure-driven valve 1 is newly assembled in accordance with a specific combination selected from the candidate combinations, the assembly condition presentation device 7 determines during assembly inspection whether or not the specifications of the fluid-pressure-driven valve 1 are satisfied, based on the condition reference data and property reference data registered in the database 2 and the condition diagnosis data measured by the fluid-pressure-driven valve 1.

[0025] The properties of the fluid pressure driven valve 1 indicate, for example, the remaining life of the fluid pressure driven valve 1 with the time of assembly inspection as the reference point in time. The property reference data is data obtained by converting the period from the time of assembly inspection to the time of detection of the abnormality as the remaining life of the fluid pressure driven valve 1 when an abnormal state is determined based on the operating state when opening and closing operations are performed on the fluid pressure driven valve 1 installed in a test facility or an actual facility after assembly inspection.

[0026] The assembly inspection includes not only an inspection performed before shipment from a factory after the fluid pressure driven valve 1 is newly assembled, but also an inspection performed after the fluid pressure driven valve 1 is overhauled or parts are replaced.

[0027] In the following, first, the fluid pressure driven valve 1 that is the target of support by the assembly support system 100 will be described in detail, and then the database generating device 6 and the assembly condition presenting device 7 will be described in detail.

[0028] (Fluid pressure valve 1) 2 is a schematic diagram showing an example of a fluid pressure driven valve 1 according to an embodiment of the present invention. The fluid pressure driven valve 1 includes a main valve 3, a drive unit 4, and a solenoid valve 5.

[0029] The fluid pressure driven valve 1 shown in Fig. 2 employs an airless close system. During normal operation, the main valve 3 is opened by supplying air A (intake air) from the air supply source 13 to the drive unit 4 via the solenoid valve 5, and during emergency stop or test operation, the main valve 3 is closed by discharging air A (exhaust air) from the drive unit 4 via the solenoid valve 5. Note that the fluid pressure driven valve 1 may employ an airless open system, in which case the main valve 3 is closed by supplying air A to the drive unit 4 and opened by discharging air A from the drive unit 4.

[0030] In the fluid pressure driven valve 1, a first air pipe 130 connecting the air supply source 13 and the solenoid valve 5, and a second air pipe 131 connecting the solenoid valve 5 and the drive unit 4 are provided as flow paths for the air A. Note that the drive fluid is not limited to the above air A, and may be other gases or liquids (e.g., oil).

[0031] The fluid pressure driven valve 1 includes a communication cable 140 for transmitting and receiving various data between the external device 14 and the solenoid valve 5, and a power cable 150 for supplying power from the external power source 15 to the solenoid valve 5. Connected.

[0032] The external device 14 is a device that transmits and receives various information to and from the fluid pressure driven valve 1. 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 5, and wireless communication may also be used.

[0033] A ball valve is used for the main valve 3 shown in Fig. 2. Specifically, the main valve 3 includes a valve box 30 disposed midway through the piping 11, and a ball-shaped valve element 31 rotatably provided within the valve box 30, 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 30, and the main valve 3 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 3 is not limited to a ball valve, and may be, for example, a butterfly valve or other on-off valve.

[0034] The drive device 4 shown in Fig. 2 employs a single-acting air cylinder mechanism. The drive device 4 includes, as specific configurations, a cylinder 40 having a spring chamber 47 and a cylinder chamber 48, a pair of pistons 42A, 42B that are arranged in the cylinder 40 so as to be capable of linearly reciprocating and connected via a piston rod 41, a coil spring 43 arranged in the spring chamber 47 on the first piston 42A side, an air supply / discharge port 44 connected to the cylinder chamber 48 on the second piston 42B side, and a transmission mechanism 45 provided at a portion where the valve shaft 12 arranged to penetrate the cylinder 40 in the radial direction and the piston rod 41 intersect at right angles. The drive device 4 is not limited to a single-acting type, and may be configured in another form, such as a double-acting type.

[0035] The first piston 42A is biased by a coil spring 43 in a direction to close the main valve 3. The second piston 42B is pressed in a direction to open the main valve 3 against the biasing force of the coil spring 43 by air A (supply air) supplied from an air supply / discharge port 44. The transmission mechanism 45 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 41 into rotational motion and transmits it to the valve shaft 12.

[0036] 2 employs a two-position normally closed type three-way solenoid valve ("open" when energized, "closed" when de-energized). The solenoid valve 5 specifically includes, inside a housing 50, a spool portion 51 that switches the flow path through which air A flows, a solenoid portion 52 that displaces the spool portion 51 depending on the energized state (when energized or de-energized), and a sensor group 53 that measures physical quantities and state quantities of each portion of the solenoid valve 5. The solenoid valve 5 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.

[0037] The accommodating section 50 functions as a housing for the indoor or explosion-proof solenoid valve 5. The accommodating section 50 includes a shaft insertion port 500 into which the valve shaft 12 (third shaft 12c) is inserted, and a cable insertion port 501 into which the communication cable 140 and the power cable 150 are inserted.

[0038] The spool portion 51 has an input port 510 connected to the air supply source 13 via a first air pipe 130, an output port 511 connected to the drive unit 4 via a second air pipe 131, and an exhaust port 512 for discharging exhaust air from the drive unit 4.

[0039] When energized, the solenoid portion 52 displaces the spool portion 51 so as to connect the input port 510 and the output port 511 to each other, and when deenergized, the solenoid portion 52 displaces the spool portion 51 so as to connect the output port 511 and the exhaust port 51 2. The spool portion 51 is displaced so as to communicate with the

[0040] The sensor group 53 is disposed at various locations inside the storage section 50. The sensor group 53 includes, for example, a first pressure sensor 530 that measures the fluid pressure of the air A flowing through a first flow path 502 that communicates with the input port 510, a second pressure sensor 531 that measures the fluid pressure of the air A flowing through a second flow path 503 that communicates with the output port 511, and a main valve opening sensor 532 that measures the rotation angle when the valve shaft 12 (third shaft 12c) rotates and acquires valve opening information of the main valve 3 according to the rotation angle.

[0041] The main valve opening sensor 532 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 3 according to the magnetic field strength.

[0042] 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 penetrate the drive unit 4 and is driven by the drive unit 4. The second shaft 12b is connected to the first shaft 12a and is also connected to the main valve 3. The third shaft 12c is connected to the first shaft 12a and is inserted into the housing portion 50 of the solenoid valve 5 and is supported. The valve shaft 12 performs a rotational motion as a whole in synchronization with the first shaft 12a being driven by the drive unit 4.

[0043] In the fluid pressure driven valve 1 having the above configuration, when the solenoid valve 5 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 510, the output port 511, and the second air piping 131 in this order, and is supplied to the air supply / discharge port 44, thereby pressing the second piston 42B and compressing the coil spring 43. Then, when the first shaft 12a (valve shaft 12) is rotated via the piston rod 41 and the transmission mechanism 45 by an amount corresponding to the movement of the piston rod 41 in response to the compression of the coil spring 43, the valve element 31 rotates within the valve box 30, and the main valve 3 is operated to a fully open state.

[0044] On the other hand, when the solenoid valve 5 is in a non-energized state, the air A (exhaust) in the cylinder 40 flows from the air supply / exhaust port 44 through the second air pipe 131, the output port 511, and the exhaust port 512 in this order, and is discharged to the outside air, thereby reducing the pressing force of the second piston 42B and causing the coil spring 43 to restore from the compressed state. Then, when the first shaft 12a (valve shaft 12) is rotated via the transmission mechanism 45 by the amount of movement of the piston rod 41 in response to the restoration of the coil spring 43, the valve element 31 rotates in the valve box 30, and the main valve 3 is operated to the fully closed state.

[0045] Fig. 3 is a schematic block diagram showing an example of the fluid pressure driven valve 1 according to an embodiment of the present invention. As shown in Fig. 3, the solenoid valve 5 includes, as an example of an electrical configuration, a control unit 54 for controlling the solenoid valve 5, a communication unit 55 for communicating with the external device 14, and a power supply circuit unit 56 connected to the external power supply 15, in addition to the solenoid unit 52 and the sensor group 53 described above.

[0046] In addition to the first pressure sensor 530, second pressure sensor 531, and main valve opening sensor 532 described above, the sensor group 53 includes a voltage sensor 533 that measures the voltage supplied to the solenoid section 52, a current / resistance sensor 534 that measures the current value when current is applied to the solenoid section 52 and the resistance value when current is not applied, a temperature sensor 535 that measures the internal temperature of the accommodating section 50, and a magnetic sensor 536 that measures the strength of the magnetic field generated by the solenoid section 52.

[0047] The sensor group 53 is a sensor group for acquiring information on the operation history of each part. The pressure-driven valve 1 is equipped with an operation time meter (timer) 537 that measures at least one of the total time that electricity is supplied to the solenoid section 52 and the current time of electricity supply as the operation time of the pressure-driven valve 1, and an operation counter (counter) 538 that counts the number of times that the solenoid valve 5, the drive device 4, and the main valve 3 are each operated.

[0048] The sensor group 53 is not limited to the above-mentioned sensors being provided separately, and a specific sensor may also function as the other sensors, so that the other sensors do not have to be provided separately. For example, the magnetic sensor 536 measures the strength of the magnetic field generated by the solenoid unit 52 and calculates the current value when the current is applied to the solenoid unit 52 based on the magnetic field strength, so that the current / resistance sensor 534 does not have to be provided separately. The controller 540 may incorporate the sensor function or realize part of the sensor function. For example, the controller 540 may incorporate the operation hour meter 537 and the operation counter 538, so that the operation hour meter 537 and the operation counter 538 do not have to be provided separately.

[0049] The control unit 54, the communication unit 55, and the power supply circuit unit 56 are configured, for example, by a general-purpose or dedicated computer (see FIG. 4 described later).

[0050] The control unit 54 processes information indicating the physical quantities and state quantities of each part of the fluid pressure driven valve 1 measured by the sensor group 53, and is equipped with a controller 540 that controls each part of the fluid pressure driven valve 1, and a valve test switch 541 that controls the electrified state of the solenoid unit 52 and opens and closes the main valve 3 during test operation.

[0051] A condition diagnosis device 57 that diagnoses the condition of the fluid pressure driven valve 1 (e.g., the presence or absence of an abnormality, remaining life, etc.) is incorporated in the controller 540, and the controller 540 realizes a condition diagnosis function. Note that all or part of the functions of the condition diagnosis device 57 may be realized by other equipment, for example, the external device 14 or another device connected to the fluid pressure driven valve 1.

[0052] The valve test switch 541 receives a command from the controller 540 when a predetermined test operation condition is satisfied, and executes a stroke test of the fluid pressure driven valve 1 as a test operation in which a predetermined opening and closing operation is performed.

[0053] 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 3 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 3 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 3 to a fully closed state (i.e., without stopping the actual 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.

[0054] As for the test operation conditions, for example, when the execution time based on the execution frequency (e.g., once a year) set by the administrator or a specific specified date and time arrives, when an execution command is received from the external device 14, or when a test execution button (not shown) provided on the solenoid valve 5 is operated by the administrator, the test operation conditions are met and a test operation (stroke test) is executed.

[0055] When a test operation (stroke test) is performed, the condition diagnosis device 57 determines (diagnoses) whether the fluid pressure driven valve 1 is in a normal state or an abnormal state based on measurement result information indicating the physical quantities and state quantities of each part of the fluid pressure driven valve 1 measured by the sensor group 53. Then, the condition diagnosis device 57 transmits condition diagnosis data including the diagnosis time, the measurement result information, the diagnosis result, and the like to the external device 14.

[0056] The abnormal state may include a plurality of abnormal states according to the specific contents and degrees of the abnormality, for example. In this case, the state diagnosis device 57 judges whether the state of the fluid pressure driven valve 1B is a normal state or one of a plurality of abnormal states.

[0057] The abnormal state may include not only a retroactive abnormality where the occurrence of an abnormality is found at the time of judgment, but also a sign of an abnormality where the occurrence of a future abnormality is predicted, although it is within an allowable range that is judged to be normal at the time of judgment. In this case, the state diagnosis device 57 judges whether the state of the fluid pressure driven valve 1 is a normal state or an abnormal state within a preset remaining life period (for example, several hours, several days, several months, or several years). Furthermore, the state diagnosis device 57 may judge whether the state of the fluid pressure driven valve 1B is a normal state or one of a plurality of abnormal states within a preset remaining life period.

The media input / output unit 228 is composed of a drive device such as a DVD drive or a CD drive, and reads and writes data from and to a medium 270 such as a DVD or a CD.

[0063] In the computer 200 having the above configuration, the processor 212 executes the program 23. 0 into a work memory area of ​​the memory 214, and executes it to control each part of the computer 200 via the bus 210.

[0064] The computer 200 is, for example, a desktop computer or a portable computer, and is an electronic device of any type. The computer 200 may be a client computer, a server computer, or a cloud computer. The computer 200 may be applied to devices other than the database generating device 6 and the assembly condition presenting device 7.

[0065] (Database generating device 6) Figures 5 and 6 are schematic block diagrams showing an example of a database generating device 6 according to an embodiment of the present invention. Figure 7 is a data structure diagram showing an example of a database 2 according to an embodiment of the present invention.

[0066] The database generating device 6 collects judgment criteria data and property criteria data by measuring the operating state when a predetermined opening and closing operation is performed in the fluid pressure driven valves 1A, 1B to be registered, for each combination (combination to be registered) of the usage environment 10, the main valve 3, the drive device 4, and the solenoid valve 5 that constitute the fluid pressure driven valves 1A, 1B to be registered in the database 2. As shown in Fig. 5 and Fig. 6, the database generating device 6 includes a storage unit 60, an initial test data acquiring unit 61, an assembly inspection data acquiring unit 62, a durability test data acquiring unit 63, an operation data acquiring unit 64, and a database registration unit 65.

[0067] The database generating device 6 is configured to be able to communicate with various devices and systems by wired communication or wireless communication, and is connected to, for example, an external device 14, an assembly condition presentation device 7, a test facility 8, an assembly inspection facility 9A, and the fluid pressure driven valves 1A and 1B to be registered. The database generating device 6 may be connected to the fluid pressure driven valves 1A and 1B via the external device 14. Also, there may be a plurality of test facilities 8 and assembly inspection facilities 9A.

[0068] The test facility 8 is a facility for carrying out an initial test and a durability test on a virtual fluid pressure driven valve 1A corresponding to a combination of registered objects. As shown in FIG. 5, the test facility 8 includes an operator terminal device 80 and a virtual load unit 81.

[0069] The virtual load unit 81 is configured with a device capable of virtually reproducing the load state when the main valve 3 is driven in the usage environment 10 for each combination of multiple types of main valves 3 and multiple types of usage environments 10. The virtual load unit 81 is configured with, for example, a disk brake device, and is connected to the second shaft 12b. The disk brake device adjusts the braking force on the second shaft 12b to reproduce the load state acting on the second shaft 12b when the main valve 3 to be registered is driven in the usage environment 10 to be registered.

[0070] The virtual fluid pressure driven valve 1A corresponding to the combination of the registered objects is composed of a virtual load section 81 in which a load state that reproduces the use environment 10 and the main valve 3 to be registered is set, and the drive unit 4 and the solenoid valve 5 to be registered. That is, the virtual fluid pressure driven valve 1A is composed of the virtual load section 81 and the registered main valve 3 connected to the virtual load section 81 via a first shaft 12a and a second shaft 12b. The system is composed of a target drive unit 4 and a registration target solenoid valve 5 into which a third shaft 12c connected to a first shaft 12a is inserted.

[0071] The assembly inspection equipment 9A is equipment for carrying out an assembly inspection on the actual fluid pressure driven valve 1B corresponding to the combination of the registered objects. As shown in FIG. 6, the assembly inspection equipment 9A includes an operator terminal device 90 and a use environment reproducing unit 91.

[0072] The use environment reproducing unit 91 includes a simulated pipe 92 that reproduces the pipe 11 in the actual facility, and by adjusting the fluid pressure of the control fluid flowing through the simulated pipe 92, a variety of use environments 10 are virtually reproduced.

[0073] The actual fluid pressure-driven valve 1B corresponding to the combination to be registered is constructed by newly assembling the main valve 3, drive unit 4, and solenoid valve 5 to be registered by connecting them with a valve shaft 12, and installing them in a simulated piping 92 in which the fluid pressure of the control fluid is adjusted to reproduce the usage environment 10 to be registered.

[0074] The database generating device 6 is configured, for example, by a computer 200 shown in Fig. 4. In this case, the memory unit 60 is configured by a storage device 220, and the initial test data acquiring unit 61, the assembly inspection data acquiring unit 62, the durability test data acquiring unit 63, the operation data acquiring unit 64 and the database registration unit 65 are configured by a processor 212 and the like.

[0075] The storage unit 60 stores various data such as a database 2. As shown in Fig. 7, the database 2 is configured to be able to register judgment criteria data and property criteria data in association with each combination of multiple types of use environments 10, multiple types of main valves 3, multiple types of drive devices 4, and one or multiple types of solenoid valves 5. The database 2 is capable of not only registering new records, but also searching, extracting, and referencing registered records, as well as updating or deleting them.

[0076] In the database 2 shown in FIG. 7, for the sake of simplicity, symbols are used to represent the data in each field of the usage environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5. However, information specifying the conditions of the usage environment 10 is input into the field of the usage environment 10, and information specifying the respective types (e.g., model name, type name, model number, etc.) is input into the fields of the main valve 3, the drive unit 4, and the solenoid valve 5.

[0077] The initial test data acquisition unit 61 acquires, as judgment criteria data, the operating state when opening and closing operations are performed on the virtual fluid-pressure-driven valve 1A during initial testing (performed in test equipment 8) of the virtual fluid-pressure-driven valve 1A corresponding to the combination of registered objects.

[0078] The assembly inspection data acquisition unit 62 acquires, as judgment criteria data, the operating state when opening and closing operations are performed on the actual fluid-pressure driven valve 1B during assembly inspection (performed in assembly inspection equipment 9A) of the actual fluid-pressure driven valve 1B corresponding to the combination to be registered.

[0079] The opening and closing operations when the initial test data acquiring unit 61 and the assembly inspection data acquiring unit 62 acquire the judgment reference data are performed by a common stroke test. The opening and closing operations may be performed multiple times. In this case, the initial test data acquiring unit 61 and the assembly inspection data acquiring unit 62 may acquire the judgment reference data by averaging the data from each time or selecting representative data.

[0080] The initial test data acquisition unit 61 and the assembly inspection data acquisition unit 62 are connected to the solenoid valves 5 constituting the virtual fluid pressure driven valve 1A and the actual fluid pressure driven valve 1B, respectively, and are used to acquire the sensor data of the solenoid valves 5. The judgment reference data is obtained based on the measurement results obtained by the sensor group 53.

[0081] In this case, the initial test data acquisition unit 61 and the assembly inspection data acquisition unit 62 acquire judgment criteria data that include at least time series data on the valve opening degree of the main valve 3 during the opening and closing operation and time series data on the solenoid valve output side pressure of air A supplied and exhausted from the solenoid valve 5 to the drive unit 4 during the opening and closing operation, as the operating state when opening and closing operations are performed on the virtual fluid pressure driven valve 1A and the actual fluid pressure driven valve 1B, respectively.

[0082] The valve opening of the main valve 3 is measured by a main valve opening sensor 532. The solenoid valve output side pressure of air A is the pressure of air A supplied to or exhausted from the solenoid valve 5 to the drive device 4, and includes the pressure of air A (supply air) when air A is supplied from the solenoid valve 5 to the drive device 4, and the pressure of air A (exhaust air) when air A is exhausted from the drive device 4 to the outside air via the solenoid valve 5. The solenoid valve output side pressure of air A is measured by a second pressure sensor 531.

[0083] Furthermore, when the database generating device 6 includes a group of sensors 66 for a test facility, the initial test data acquiring unit 61 and the assembly inspection data acquiring unit 62 may each acquire the judgment reference data based on the measurement results measured by the group of sensors 66 for a test facility. The group of sensors 66 for a test facility includes, for example, at least one of a first torque sensor 660A that measures a first acting torque acting between the first shaft 12a and the second shaft 12b, and a second torque sensor 660B that measures a first acting torque acting between the first shaft 12a and the second shaft 12b.

[0084] In this case, the initial test data acquiring unit 61 and the assembly inspection data acquiring unit 62 acquire, as operating states when opening and closing operations are performed in the virtual fluid pressure driven valve 1A and the actual fluid pressure driven valve 1B, judgment reference data including at least time series data of the acting torque acting on the valve stem 12 during opening and closing operations in addition to or instead of time series data of the valve opening degree of the main valve 3 and time series data of the solenoid valve output side pressure of air A. The acting torque is measured by at least one of the first torque sensor 660A and the second torque sensor 660B.

[0085] The time series data is composed of a plurality of pieces of data measured at different times within a predetermined period, and is acquired, for example, at a predetermined sampling period. In this embodiment, the time series data of the valve opening of the main valve 3, the time series data of the solenoid valve output side pressure of air A, and the time series data of the acting torque are measured at a plurality of times with the same sampling period and the same phase (without phase difference), but at least one of the sampling period and the phase may be different.

[0086] The predetermined period is a period during which the main valve 3 is opened and closed, and corresponds to, for example, a period during which a stroke test is performed on the fluid pressure driven valve 1. The predetermined period may be the entire period during which the stroke test is performed, from the start of the test to the end of the test, or a part of that period. Therefore, the predetermined period may be, for example, the entire period of the full stroke test (fully open state → fully closed state → fully open state), the entire period of the partial stroke test (fully open state → partially closed state), a part of the full stroke test (fully open state → fully closed state, or fully closed state → fully open state, etc.), or a part of the partial stroke test (fully open state → partially closed state, partially closed state → fully open state, etc.), but is not limited thereto.

[0087] Optionally, the judgment criteria data may be acquired based on the measurement results measured by the sensor group 53 other than the main valve opening sensor 532 and the second pressure sensor 531. For example, the judgment criteria data may be time series data of the solenoid valve input side pressure of air A supplied from the air supply source 13 to the solenoid valve 5, time series data of the differential pressure between the solenoid valve input side pressure and the solenoid valve output side pressure of air A, control parameters of the solenoid unit 52 (supply voltage, current value when energized, resistance value when not energized), The time series data may further include time series data of the magnetic field strength, magnetic field intensity, etc., time series data of the temperature of the solenoid valve 5, the total operating time of the fluid pressure driven valve 1, the operating time since power was last applied to the fluid pressure driven valve 1, the number of operations of the main valve 3, the number of operations of the drive device 4, the number of operations of the solenoid valve 5 (mainly the solenoid portion 52), and the opening and closing time of the main valve 3.

[0088] The durability test data acquisition unit 63 performs a durability test (or an accelerated test) in which the virtual fluid-pressure-driven valve 1A installed in the test facility 8 is repeatedly opened and closed, and when the condition diagnosis function determines that an abnormal condition exists, estimates the remaining life (based on the time of the initial test) of the fluid-pressure-driven valve 1A from the number of opening and closing operations and the operating condition, and acquires the remaining life as characteristic reference data.

[0089] When the operation data acquisition unit 64 receives from the fluid pressure driven valve 1B (condition diagnosis device 57) condition diagnosis data indicating that a test operation (stroke test) has been performed on the actual fluid pressure driven valve 1B installed in the piping 11 of the actual equipment and that the condition has been determined to be abnormal, the operation data acquisition unit 64 determines the remaining life (based on the time of assembly inspection) of the fluid pressure driven valve 1B from various information included in the condition diagnosis data (diagnosis time, measurement result information, diagnosis result, etc.) and acquires the remaining life as characteristic reference data.

[0090] The database registration unit 65 associates the judgment criterion data and property criterion data acquired by the virtual fluid pressure driven valve 1A with the combination of the use environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5 that constitute the virtual fluid pressure driven valve 1A, and registers them in the database 2. That is, the database registration unit 65 registers (adds) in the database 2 a new record (one line of data in FIG. 7) that associates the combination of registration targets that constitute the virtual fluid pressure driven valve 1A when the initial test data acquisition unit 61 acquires the judgment criterion data with the judgment criterion data, and thereafter, when the durability test data acquisition unit 63 acquires the property criterion data, it registers the property criterion data in the same record.

[0091] The database registration unit 65 associates the judgment criterion data and property criterion data acquired in the actual fluid pressure driven valve 1B with the combination of the use environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5 that constitute the actual fluid pressure driven valve 1B, and registers them in the database 2. That is, the database registration unit 65 registers (adds) in the database 2 a new record (one line of data in FIG. 7) that associates the combination of registration targets that constitute the actual fluid pressure driven valve 1B when the assembly inspection data acquisition unit 62 acquires the judgment criterion data with the judgment criterion data, and thereafter, when the operation data acquisition unit 64 acquires the property criterion data, registers the property criterion data in the same record.

[0092] (Database generation method) FIG. 8 is a flowchart showing an example of a database generation method by the database generation device 6 according to the embodiment of the present invention when a virtual fluid pressure driven valve 1A is used.

[0093] First, in step S100, when an operator operates the operator terminal device 80 of the test equipment 8 shown in FIG. 5 to specify a combination of the usage environment 10, main valve 3, drive device 4, and solenoid valve 5 that constitute the virtual fluid pressure driven valve 1A to be registered (the combination to be registered), the database registration unit 65 of the database generation device 6 accepts the specification operation.

[0094] Next, in step S110, an operator attaches the driving device 4 and solenoid valve 5 to be registered to the virtual load section 81 of the test equipment 8. At this time, the virtual load section 81 and the driving device 4 to be registered are connected via the first shaft 12a and the second shaft 12b, and the driving device 4 to be registered and the solenoid valve 5 to be registered are connected via the first shaft 12a and the third shaft 12c. In addition, if necessary, a first torque sensor 660A is attached between the first shaft 12a and the second shaft 12b, and a second torque sensor 660B is attached between the first shaft 12a and the second shaft 12b. , mounted between the first shaft 12a and the third shaft 12c.

[0095] Next, in step S120, the operator sets a load state that reproduces the combination of the usage environment 10 and the main valve 3 to be registered in the virtual load unit 81, thereby configuring a virtual fluid pressure driven valve 1A corresponding to the combination to be registered. Note that, if the virtual load unit 81 is configured to be able to automatically set the load state, the virtual load unit 81 automatically sets the load state according to the data corresponding to the combination to be registered designated in step S100.

[0096] Next, in step S130, when the operator operates the operator terminal device 80 to input that the setting work is completed, the initial test data acquiring unit 61 accepts the setting completion operation and performs an opening and closing operation with the virtual fluid pressure driven valve 1A. The opening and closing operation is performed by a stroke test, for example, by transmitting a command from the initial test data acquiring unit 61 to the valve test switch 541 of the solenoid valve 5.

[0097] Then, in step S140, in parallel with step S130, the initial test data acquiring unit 61 acquires criterion data based on the measurement results measured by the sensor group 53 of the solenoid valve 5 when the opening and closing operation is performed. The initial test data acquiring unit 61 acquires, as criterion data, time series data on the valve opening of the main valve 3 and time series data on the solenoid valve output side pressure of air A, for example, based on the measurement results measured by the main valve opening sensor 532 and the second pressure sensor 531, respectively.

[0098] Next, in step S150, the database registration unit 65 registers in the database 2 the combination to be registered designated in step S100 in association with the criterion data acquired in step S140.

[0099] Next, in step S160, when the operator operates the operator terminal device 80 to instruct the execution of a durability test, a durability test is executed in which the virtual fluid pressure driven valve 1A is repeatedly opened and closed.

[0100] Next, in step S170, when the durability test data acquisition unit 63 determines that an abnormal state exists based on the operating state when the opening and closing operations are performed in the durability test, it estimates the remaining life (based on the time of the initial test) of the virtual fluid pressure driven valve 1A from the number of opening and closing operations and the operating state, and acquires the remaining life as characteristic reference data.

[0101] Next, in step S180, the database registration unit 65 associates the property reference data acquired in step S170 with the combination of registration targets designated in step S100 and registers them in the database 2. Then, the database generation method shown in Fig. 8 is terminated. In the database generation method, steps S140 and S170 correspond to a registration data acquisition step, and steps S150 and S180 correspond to a database registration step. Note that the database generation method shown in Fig. 8 is executed for each combination of registration targets.

[0102] FIG. 9 is a flowchart showing an example of a database generation method by the database generation device 6 according to the embodiment of the present invention when an actual fluid pressure driven valve 1B is used.

[0103] First, in step S200, when an operator operates the operator terminal device 90 of the assembly inspection equipment 9A shown in FIG. 6 to specify a combination of the usage environment 10, the main valve 3, the drive device 4, and the solenoid valve 5 that constitute the actual fluid pressure driven valve 1B to be registered (the combination to be registered), the database registration unit 65 of the database generation device 6 accepts the specification operation.

[0104] Next, in step S210, the worker performs the following on the simulated piping 92 of the assembly inspection equipment 9A: Then, the main valve 3, the drive unit 4, and the solenoid valve 5 to be registered are attached. Furthermore, a first torque sensor 660A and a second torque sensor 660B are attached as necessary.

[0105] Next, in step S220, the operator adjusts the usage environment reproducing unit 91 to the fluid pressure of the control fluid that reproduces the usage environment 10 to be registered, thereby configuring an actual fluid pressure-driven valve 1B that corresponds to the combination to be registered. If the usage environment reproducing unit 91 is configured to be able to automatically adjust the fluid pressure, the usage environment reproducing unit 91 automatically adjusts the fluid pressure according to the data corresponding to the combination to be registered designated in step S200.

[0106] Next, in step S230, when the operator operates the operator terminal device 90 to input that the setting work is completed, the assembly inspection data acquisition unit 62 accepts the setting completion operation and performs an opening and closing operation with the actual fluid pressure driven valve 1B. The opening and closing operation is performed by a stroke test, similar to step S130.

[0107] Then, in step S240, in parallel with step S230, the assembly inspection data acquiring unit 62 acquires judgment reference data based on the measurement results measured by the sensor group 53 of the solenoid valve 5 when the opening and closing operation is performed. The assembly inspection data acquiring unit 62 acquires, as judgment reference data, time series data on the valve opening of the main valve 3 and time series data on the solenoid valve output side pressure of air A, based on the measurement results respectively measured by the main valve opening sensor 532 and the second pressure sensor 531, for example.

[0108] Next, in step S250, the database registration unit 65 registers in the database 2 the combination to be registered designated in step S200 in association with the criterion data acquired in step S240.

[0109] Next, in step S260, the fluid pressure driven valve 1B is removed from the simulated piping 92, and the assembly inspection in the assembly inspection equipment 9A is completed. The assembly inspection equipment 9A not only acquires the judgment criteria data, but also performs the assembly inspection based on various inspection items, but the description thereof will be omitted here. The actual fluid pressure driven valve 1B that has passed the assembly inspection in the assembly inspection equipment 9A is then installed in the piping 11 of the actual equipment and used, for example, as an emergency shutoff valve.

[0110] Next, in step S270, the fluid pressure driven valve 1B installed in the piping 11 of the actual equipment undergoes a stroke test by the condition diagnosis device 57 when predetermined test operation conditions are satisfied.

[0111] Next, in step S280, when the operating data acquisition unit 64 receives from the fluid pressure driven valve 1B (condition diagnosis device 57) condition diagnosis data that is determined to be abnormal based on the operating state when the opening and closing operation is performed in the stroke test, the operating data acquisition unit 64 estimates the remaining life (based on the time of assembly inspection) of the fluid pressure driven valve 1B from the condition diagnosis data and acquires the remaining life as characteristic reference data.

[0112] Next, in step S290, the database registration unit 65 associates the property reference data acquired in step S280 with the combination of registration targets designated in step S200 and registers them in the database 2. Then, the database generation method shown in Fig. 9 is terminated. In the database generation method, steps S240 and S280 correspond to a registration data acquisition step, and steps S250 and S290 correspond to a database registration step. Note that the database generation method shown in Fig. 9 is executed for each combination of registration targets.

[0113] As described above, according to the database generating device 6 and the database generating method of the present embodiment, the load corresponding to the combination of the usage environment 10 and the main valve 3 to be registered in the test facility 8 is generated. A virtual fluid pressure driven valve 1A is constructed by reproducing the state by the virtual load section 81. As a result, the judgment reference data and the property reference data are obtained using the virtual fluid pressure driven valve 1A.

[0114] In addition, in the assembly inspection equipment 9A, the judgment criteria data is obtained using the actual fluid pressure driven valve 1B, and then the actual fluid pressure driven valve 1B is installed in the actual equipment and a stroke test is performed to obtain the property reference data. In this way, the judgment criteria data and the property reference data are obtained using the actual fluid pressure driven valve 1B.

[0115] Therefore, for each combination of registered objects consisting of the four elements of the use environment 10, the main valve 3, the drive device 4, and the solenoid valve 5, the judgment criterion data and the property criterion data can be easily collected.

[0116] (Assembly condition presentation device 7) FIG. 10 is a schematic block diagram showing an example of an assembly condition presentation device 7 and an assembly inspection facility 9B according to an embodiment of the present invention.

[0117] When the assembly condition presentation device 7 receives the required properties of the fluid-pressure driven valve 1C and the usage environment 10 in which the fluid-pressure driven valve 1C will be used as specifications for the newly assembled fluid-pressure driven valve 1C, it refers to the database 2 based on the specifications and extracts and presents candidate combinations of the main valve 3, drive unit 4, and solenoid valve 5 that satisfy the specifications.

[0118] In addition, when the assembly condition presentation device 7 determines that a newly assembled fluid-pressure-driven valve 1C assembled according to a specific combination selected from candidate combinations is to be judged in the assembly inspection, the assembly condition presentation device 7 refers to the database 2 based on the combination of the usage environment 10, the main valve 3, the drive device 4, and the solenoid valve 5 constituting the fluid-pressure-driven valve 1C (the combination to be judged), and determines during the assembly inspection whether or not the properties of the fluid-pressure-driven valve 1C to be judged satisfy the specifications of the fluid-pressure-driven valve 1C.

[0119] As shown in FIG. 10, the assembly condition presentation device 7 includes a memory unit 70, a specification receiving unit 71, a candidate extraction unit 72, a reference data acquisition unit 73, a judgment target data acquisition unit 74, a property judgment unit 75, and an information presentation unit 76.

[0120] The assembly condition presentation device 7 is configured to be able to communicate with various devices and systems by wired communication or wireless communication, and is connected to, for example, a designer terminal device 700, an external device 14, a database generation device 6, an assembly inspection facility 9B, and the fluid pressure driven valve 1C to be judged. The assembly condition presentation device 7 may be connected to the fluid pressure driven valve 1C via the external device 14. Also, there may be a plurality of designer terminal devices 700 and a plurality of assembly inspection facilities 9B.

[0121] The assembly inspection equipment 9B is equipment for carrying out an assembly inspection on the fluid pressure driven valve 1C to be judged. The assembly inspection equipment 9B is configured similarly to the assembly inspection equipment 9A shown in FIG. 6, and includes an operator terminal device 90 and a use environment reproducing unit 91.

[0122] The fluid pressure-driven valve 1C corresponding to the combination to be judged is constructed by newly assembling the main valve 3, drive unit 4, and solenoid valve 5 to be judged by connecting them with a valve shaft 12, and installing them in a simulated piping 92 in which the fluid pressure of the control fluid is adjusted to reproduce the usage environment 10 to be judged.

[0123] The assembly condition presentation device 7 is configured, for example, by a computer 200 shown in Fig. 4. In this case, the memory unit 70 is configured by a storage device 220, and includes a specification reception unit 71, a candidate extraction unit 72, a reference data acquisition unit 73, a judgment target data acquisition unit 74, a property judgment unit 75, and an information presentation unit 7 6 is composed of a processor 212 and the like.

[0124] The storage unit 70 stores various data such as a database 2. The database 2 is provided from the database generating device 6 via any communication network or storage medium. In this case, the database 2 may include all data, or may be limited to a portion of the data. Note that the database 2 stored in the storage unit 60 of the database generating device 6 may be referenced as the database 2.

[0125] The specification receiving unit 71 receives, as specifications of a newly assembled fluid pressure driven valve 1C, the properties required of the fluid pressure driven valve 1C and the usage environment 10 in which the fluid pressure driven valve 1C is to be used. The specifications may be specified by a specific value or a specific type, may be specified by multiple values ​​or multiple types, or may be specified within a specific range.

[0126] The candidate extraction unit 72 refers to the database 2 stored in the storage unit 70, and extracts candidates for combinations of the main valve 3, the drive unit 4, and the solenoid valve 5 that constitute the fluid pressure driven valve 1C that satisfy the specifications (properties and usage environment 10) accepted by the specification acceptance unit 71. As for the candidate combinations, one candidate may be extracted, or multiple candidate combinations may be extracted, and when multiple candidate combinations are extracted, they may be ranked based on the degree of match with the specifications.

[0127] The reference data acquisition unit 73 refers to the database 2 stored in the memory unit 70, and acquires judgment criteria data and property criteria data associated with the combination of the usage environment 10, main valve 3, drive unit 4, and solenoid valve 5 that constitute the fluid pressure driven valve 1C to be judged (the combination to be judged).

[0128] For example, when the assembly condition presentation device 7 specifies a combination of objects to be judged (use environment 102, main valve 32, drive device 42, solenoid valve 52) as shown in a solid line frame in Fig. 10, it acquires the judgment criteria data "Data4A", "Data4B" and property criteria data "Data4C" associated with ID "4" in the database 2 shown in Fig. 7. Note that the specification data of the fluid pressure driven valve 1 indicating the combination of objects to be judged may be stored in the controller 540 of the solenoid valve 5 or the storage unit 70 during assembly of the fluid pressure driven valve 1, and in that case, the criteria data acquisition unit 73 may specify the combination of objects to be judged by referring to the specification data.

[0129] The judgment target data acquisition unit 74 acquires, as judgment target data, an operating state when an opening / closing operation is performed on the fluid pressure driven valve 1C to be judged. The opening / closing operation when the judgment target data acquisition unit 74 acquires the judgment target data is performed, for example, by a stroke test. Note that the opening / closing operation may be performed multiple times, in which case the judgment target data acquisition unit 74 may acquire judgment criterion data by averaging the data from each time or selecting representative data.

[0130] The determination target data acquisition unit 74 is connected to the solenoid valve 5 constituting the fluid pressure driven valve 1C to be determined, and acquires determination target data based on the measurement results measured by the sensor group 53 of the solenoid valve 5. In this case, the determination target data acquisition unit 74 acquires determination target data including at least time series data of the valve opening degree of the main valve 3 during the opening and closing operation, and time series data of the solenoid valve output side pressure of the air A supplied and exhausted from the solenoid valve 5 to the drive device 4 during the opening and closing operation, as the operating state when the opening and closing operation is performed on the fluid pressure driven valve 1C to be determined.

[0131] The target data acquisition unit 74 is connected to the sensor group 53 of the solenoid valve 5, and may be connected to a part of the sensor group 53 depending on the type and format of data included in the judgment criteria data, or may be connected to the entire sensor group 53 and select data to be acquired as target data from the measurement results of the sensor group 53.

[0132] The property determination unit 75 compares the determination reference data with the data to be determined, and determines whether or not the fluid pressure driven valve 1C to be determined satisfies the property (hereinafter referred to as "required property") accepted as a specification by the specification acceptance unit 71 (suitability of the specification) based on the comparison result and the property reference data. In addition, the property determination unit 75 determines whether or not to perform readjustment on the fluid pressure driven valve 1C to be determined (adoption or rejection of readjustment) or whether or not to adopt a candidate for another combination (adoption or rejection of another combination) based on the comparison result and the property reference data.

[0133] For example, the property determination unit 75 compares the determination reference data with the data to be determined, estimates the property (hereinafter referred to as the "estimated property") of the fluid pressure driven valve 1C to be determined based on the comparison result and the property reference data, determines whether the estimated property satisfies the required property, and sends the determination result to the information presentation unit 76. Then, if the property determination unit 75 determines that the estimated property does not satisfy the required property, it determines whether to readjust the fluid pressure driven valve 1C or whether to adopt another candidate combination, and sends the determination result to the information presentation unit 76.

[0134] The readjustment is, for example, readjustment of the tightening torque of the seal portion (not shown) of the main valve 3 during assembly, the assembly position between parts, etc., and the property determination unit 75 determines whether to adopt the readjustment depending on whether the degree of dissatisfaction when it is determined that the estimated property does not satisfy the specified property can be resolved by the readjustment. The other candidate combination is, for example, another candidate combination when a plurality of candidate combinations is extracted by the candidate extraction unit 72, and the property determination unit 75 determines whether to adopt the other candidate combination depending on whether the degree of dissatisfaction when it is determined that the estimated property does not satisfy the specified property can be resolved by the other candidate combination.

[0135] The method for estimating the property of the fluid pressure driven valve 1C to be judged is appropriately selected according to the type and format of data included in the judgment reference data and judgment target data.

[0136] When the judgment criteria data and the judgment target data include, as operating states, time series data on the valve opening degree of the main valve 3 and time series data on the solenoid valve output side pressure of air A, the property judgment unit 75 estimates the properties of the fluid pressure driven valve 1C based on the similarity when comparing the judgment criteria data with the judgment target data.

[0137] Furthermore, when the judgment criteria data includes time series data of the acting torque, the property judgment unit 75 estimates the time series data of the acting torque by inputting the time series data of the valve opening of the main valve 3 and the time series data of the solenoid valve output side pressure of air A, which are included in the judgment target data, into a predetermined estimation formula or learning model, and estimates the property of the fluid pressure driven valve 1C based on the similarity when comparing the judgment criteria data (time series data of the acting torque) with the estimated time series data of the acting torque.

[0138] The similarity is calculated, for example, by calculating the difference between the time series data included in the judgment reference data and the time series data included in the judgment target data at each time when the data are represented as a graph of time progression, and then summing the difference values ​​at each time or based on a statistical value (e.g., average value, standard deviation, etc.) for the difference values ​​at each time. In this case, the similarity is calculated such that the smaller the sum value or statistical value, the higher the similarity. Note that the similarity may be calculated, for example, by calculating the difference between statistical values ​​(e.g., regression coefficients of a regression equation, etc.) representative of each graph and based on the difference value.

[0139] When the property determining unit 75 estimates the remaining life as a property of the fluid pressure driven valve 1C, for example, the property determining unit 75 compares the judgment reference data with the judgment target data, and corrects the remaining life based on the property reference data on the basis of the similarity at that time, thereby estimating the remaining life of the fluid pressure driven valve 1C to be determined. The higher the degree of similarity when compared with the data, the closer the remaining life of the fluid pressure driven valve 1C being judged is estimated to be to the remaining life that is the standard in the property reference data.

[0140] The estimation of the properties by the property determination unit 75 utilizes the characteristic that when there is a high degree of similarity between the determination reference data acquired during assembly inspection of the registered fluid-pressure driven valves 1A, 1B configured in the same combination as the combination to be determined, and the determination target data acquired during assembly inspection of the fluid-pressure driven valve 1C to be determined, the remaining life of the fluid-pressure driven valve 1C to be determined tends to be close to the remaining life (remaining life represented by the property reference data) of the registered fluid-pressure driven valves 1A, 1B from which the determination reference data was obtained.

[0141] Furthermore, when the similarity of the comparison results is low and the data to be judged is on the safe side (the side with a lower risk of abnormality occurring) compared to the judgment reference data, the property judgment unit 75 estimates that the remaining life of the fluid-pressure-driven valve 1C to be judged is longer than the remaining life used as a standard in the property reference data, and when the data to be judged is on the dangerous side (the side with a higher risk of abnormality occurring) compared to the judgment reference data, it estimates that the remaining life of the fluid-pressure-driven valve 1C to be judged is shorter than the remaining life used as a standard in the property reference data.

[0142] The information presenting unit 76 presents the combination candidates extracted by the candidate extracting unit 72 as assembly conditions.

[0143] The information presenting unit 76 presents the judgment result when the property determining unit 75 judges whether the specifications are appropriate. The information presenting unit 76 presents the judgment result when the property determining unit 75 judges whether to accept readjustment or whether to accept other combination candidates, as assembly conditions.

[0144] Various means can be adopted as specific means for presenting various pieces of information by the information presenting unit 76. The information presenting unit 76 may present the assembly conditions and the judgment results to the designer or worker, for example, by displaying or sounding them, or may store them as information in the storage unit 70, or transmit them to the database generating device 6, the designer terminal device 700, the worker terminal device 90, the external device 14, or the like.

[0145] (Assembly condition presentation method) 11 and 12 are flowcharts showing an example of an assembly condition presenting method by the assembly condition presenting device 7 according to the embodiment of the present invention.

[0146] First, in step S300, the designer operates the designer terminal device 700 to specify, as specifications for a newly assembled fluid-pressure-driven valve 1C, the properties required of the fluid-pressure-driven valve 1C and the usage environment 10 in which the fluid-pressure-driven valve 1C will be used. The specification receiving unit 71 of the assembly condition presentation device 7 then receives the specifications of the newly assembled fluid-pressure-driven valve 1C based on the specification operation.

[0147] Next, in step S310, the candidate extraction unit 72 refers to the database 2 based on the specifications received in step S310, and extracts candidates for combinations of the main valve 3, the drive device 4, and the solenoid valve 5 that constitute the fluid pressure driven valve 1C that satisfy the specifications.

[0148] Next, in step S320, the information presenting unit 76 presents (displays) the combination candidates extracted in step S320 as assembly conditions on, for example, the designer terminal device 700.

[0149] Next, in step 330, the designer selects a specific combination from the candidate combinations, creates, for example, assembly instruction information on the designer terminal device 700, and transmits it to the worker terminal device 90 of the assembly and inspection equipment 9B. and combinations thereof.

[0150] Next, in step 340, the worker displays the assembly instruction information on the worker terminal device 90, and performs the assembly work of the fluid pressure driven valve 1C according to the specific combination included in the assembly instruction information. That is, the worker newly assembles the fluid pressure driven valve 1C by connecting the main valve 3, the drive device 4, and the solenoid valve 5 corresponding to the specific combination with the valve shaft 12.

[0151] Next, in step S400, when the worker operates the worker terminal device 90 to specify a combination (combination to be judged) of the use environment 10, main valve 3, drive device 4, and solenoid valve 5 that constitute the fluid pressure driven valve 1C to be judged in the assembly inspection based on a specific combination included in the assembly instruction information, the reference data acquisition unit 73 accepts the specification operation. The combination to be judged is accepted as a specific combination selected by the designer from candidate combinations.

[0152] Next, in step S410, an operator attaches the fluid-pressure-driven valve 1C newly assembled in step S340, i.e., the main valve 3, drive unit 4, and solenoid valve 5 corresponding to the combination to be judged (specific combination), to the simulated piping 92 of the assembly inspection equipment 9B shown in FIG. 10.

[0153] Next, in step S420, the operator adjusts the usage environment reproducing unit 91 to the fluid pressure of the control fluid that reproduces the usage environment 10 to be determined, thereby configuring a fluid pressure-driven valve 1C that corresponds to the combination to be determined. If the usage environment reproducing unit 91 is configured to be able to automatically adjust the fluid pressure, the usage environment reproducing unit 91 automatically adjusts the fluid pressure according to the data corresponding to the combination to be determined specified in step S400.

[0154] Next, in step S430, when the operator operates the operator terminal device 90 to input that the setting work is completed, the judgment target data acquisition unit 74 accepts the setting completion operation and performs an opening and closing operation of the fluid pressure driven valve 1C. The opening and closing operation is performed by, for example, a stroke test by transmitting a command from the judgment target data acquisition unit 74 to the valve test switch 541 of the solenoid valve 5.

[0155] Then, in step S440, in parallel with step S430, the judgment target data acquisition unit 74 acquires judgment target data based on the measurement results measured by the sensor group 53 of the solenoid valve 5 when the opening and closing operation is performed. The judgment target data acquisition unit 74 acquires, as judgment reference data, time series data on the valve opening of the main valve 3 and time series data on the solenoid valve output side pressure of air A, for example, based on the measurement results measured by the main valve opening sensor 532 and the second pressure sensor 531, respectively.

[0156] It should be noted that the fluid pressure driven valve 1C to be judged here can also be treated as the fluid pressure driven valve 1B to be registered in the database 2. In this case, the assembly condition presentation device 7 transmits the judgement target data acquired by the judgement target data acquisition unit 74 and the specification data indicating the combination of the judgement targets to the database generation device 6, so that the assembly inspection data acquisition unit 62 acquires the judgement target data as judgement criterion data, and the database registration unit 65 associates the judgement criterion data acquired by the assembly inspection data acquisition unit 62 with the combination of the registration targets according to the specification data and registers them in the database 2.

[0157] Next, in step S450, the reference data acquisition unit 73 refers to the database 2 based on the combination of objects to be determined designated in step S400, and acquires the determination reference data and property reference data associated with the combination of objects to be determined.

[0158] Next, in step S460, the property determining unit 75 determines whether the property obtained in step S450 is The constant reference data is compared with the data to be judged acquired in step S440, and the properties (estimated properties) of the fluid pressure driven valve 1C to be judged are estimated based on the comparison result and the property reference data acquired in step S450. Then, the property determining unit 75 determines whether the estimated properties satisfy the properties (required properties) accepted as specifications by the specification accepting unit 71.

[0159] Then, in step S461, if the property determination unit 75 determines that the estimated property satisfies the required property ("Yes" in step S461), in step S470, the information presentation unit 76 presents (displays), for example, on the worker terminal device 90, that the estimated property satisfies the required property.

[0160] On the other hand, in step S461, if the property determination unit 75 determines that the estimated properties do not satisfy the required properties ("No" in step S461), in step S480, the property determination unit 75 determines whether to accept readjustment for the fluid-pressure-driven valve 1C that is the subject of judgment, or whether to accept a candidate for another combination, based on the result of the comparison between the judgment criteria data and the judgment target data and the property reference data.

[0161] Then, in step S490, the information presenting unit 76 presents (displays) on, for example, the operator terminal device 90, a message indicating that the estimated properties do not satisfy the required properties, and whether or not to accept readjustment or whether or not to accept other candidate combinations, and ends the series of assembly condition presenting methods shown in Figures 11 and 12. In the assembly condition presenting method, step S300 corresponds to a specification receiving step, step S310 corresponds to a candidate extracting step, step S450 corresponds to a reference data obtaining step, step S440 corresponds to a judgment target data obtaining step, steps S460 and S480 correspond to a property determining step, and steps S320, S470 and S490 correspond to an information presenting step.

[0162] As described above, according to the assembly condition presentation device 7 and the assembly condition presentation method of this embodiment, when the specification receiving unit 71 receives, as the specifications of a newly assembled fluid pressure driven valve 1C, the properties required of the fluid pressure driven valve 1C and the usage environment 10 in which the fluid pressure driven valve 1C is to be used, the candidate extraction unit 72 refers to the database 2 and extracts candidates for combinations of the main valve 3, the drive unit 4, and the solenoid valve 5 that constitute the fluid pressure driven valve 1C that satisfy the specifications, and the information presentation unit 76 presents, as assembly conditions, the candidates for combinations extracted by the candidate extraction unit 72. Therefore, it is possible to present combinations of components that satisfy the specifications of the fluid pressure driven valve 1C.

[0163] Furthermore, the reference data acquisition unit 73 refers to the database 2 with the fluid-pressure-driven valve 1C newly assembled according to a specific combination selected from the candidate combinations as the object of judgment for assembly inspection, and acquires judgment criterion data and property reference data associated with the combination of the usage environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5 that constitute the fluid-pressure-driven valve 1C, the judgment target data acquisition unit 74 acquires, as judgment target data, the operating state when an opening and closing operation is performed on the fluid-pressure-driven valve 1C to be judged, and the property judgment unit 75 compares the judgment criterion data with the judgment target data and judges, based on the comparison result and the property reference data, whether or not the fluid-pressure-driven valve 1C to be judged satisfies the properties accepted as specifications by the specification acceptance unit 71.

[0164] Here, the judgment reference data is data representing the operating state of a fluid pressure driven valve configured in the same combination as the fluid pressure driven valve 1C to be judged at the time of assembly inspection, and the judgment target data is data representing the operating state of the fluid pressure driven valve 1C to be judged at the time of assembly inspection. Therefore, the property judgment unit 75 compares these to obtain the difference in the operating state of the above two fluid pressure driven valves at the time of assembly inspection. And the property reference data is data representing the property (derived from the operating state after assembly inspection) of a fluid pressure driven valve configured in the same combination as the fluid pressure driven valve 1C to be judged.

[0165] Therefore, the property determining unit 75 determines the property of the fluid pressure driven valve 1C by using the same combination as that of the fluid pressure driven valve 1C to be determined. Based on the characteristics of the assembled fluid-pressure driven valve, a judgment is made as to whether the fluid-pressure driven valve 1C to be judged satisfies the characteristics accepted as specifications in a state where differences in the operating state at the time of assembly inspection are reflected. Therefore, when the fluid-pressure driven valve 1C is newly assembled, it can be appropriately judged whether each individual fluid-pressure driven valve satisfies the specifications.

[0166] (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 of which are included in the technical concept of the present invention.

[0167] In the above embodiment, the case where the fluid pressure driven valve 1 includes multiple types of main valves 3 has been described, but the main valve 3 may be of one type. The case where the fluid pressure driven valve 1 includes multiple types of drive devices 4 has been described, but the drive devices 4 may be of one type. The above embodiment, the case where the fluid pressure driven valve 1 includes multiple types of solenoid valves 5 has been described, but the solenoid valves 5 may be of one type.

[0168] In the above embodiment, the database generating device 6 and the assembly condition presenting device 7 are described as separate devices, but the database generating device 6 and the assembly condition presenting device 7 may be configured as a single device.

[0169] (Database 2 variant) 13 is a data configuration diagram showing a modified example of the database 2 according to the embodiment of the present invention. In the database 2 shown in FIG. 13, instead of the fields of the use environment 10 and the main valve 3 shown in FIG. 7, the load state L (L1, L2, ..., L t ) (the subscript t is an arbitrary integer indicating the number of types of load state L). In the load state L field, data corresponding to the combination of the usage environment 10 and the main valve 3 is registered, for example, the magnitude and amount of change of the load when the second shaft 12b (valve shaft 12) is rotated in the range of 0 degrees to 90 degrees.

[0170] When the database registration unit 65 of the database generation device 6 associates judgment data with the combination to be registered and registers it in the database 2 shown in FIG. 13 (step S150 in FIG. 8 or step S150 in FIG. 9), the load state L set for the virtual load unit 81 in step S120 is registered in the database 2 (the field for load state L), or the load state L (measured, for example, using a temporarily installed torque sensor or the like) when the second axis 12b is manually rotated after adjusting the usage environment reproducing unit 91 in step S220 is registered in the database 2 (the field for load state L).

[0171] When the candidate extraction unit 72 of the assembly condition presentation device 7 determines candidate combinations using the database 2 shown in FIG. 13 (step S310 in FIG. 12), in step S300, the specification receiving unit 71 receives, as specifications for a newly assembled fluid-pressure driven valve 1C, the properties required of the fluid-pressure driven valve 1C and the load condition L (combination of the usage environment 10 and the main valve 3) under which the fluid-pressure driven valve 1C is to be used, and the candidate extraction unit 72 extracts candidate combinations of the drive unit 4 and the solenoid valve 5 that satisfy the specifications.

[0172] 13 (step S460 in FIG. 12), the load state L (measured, for example, by a temporarily installed torque sensor or the like) when the second shaft 12b is manually rotated after the use environment reproducing section 91 is adjusted in step S420 is input to the assembly condition presenting device 7 as data corresponding to the combination of the use environment 10 and the main valve 3. Then, in step S450, the reference data acquiring section 73 refers to the database 2 shown in FIG. 13 and obtains a judgment criterion corresponding to the load state L (including the use environment 10 and the main valve 3) constituting the fluid pressure driven valve 1C to be judged and the combination of the drive unit 4 and the solenoid valve 5 (combination to be judged). Obtain basic data.

[0173] For example, when the measurement result of the load state L by the worker matches the load state L2 (which may be considered to match if it is within a predetermined range), the assembly condition presentation device 7 identifies the combination to be judged (load state L2 (corresponding to the combination of the use environment 102 and the main valve 32), the drive unit 42, and the solenoid valve 52) as shown in the solid line frame in Fig. 10, and acquires the judgment criteria data "Data4A" and "Data4B" associated with the ID "4" in the database 2 shown in Fig. 13. Then, the process from step S460 onwards is the same as in the above embodiment, and therefore the description will be omitted.

[0174] (Modification of the assembly condition presentation device 7) In the above embodiment, the specification receiving unit 71 of the assembly condition presentation device 7 has been described as receiving the properties and the usage environment 10 as the specifications of the newly assembled fluid pressure driven valve 1C. In contrast, the specification receiving unit 71 may further receive one or two of the type of the main valve 3, the type of the drive unit 4, and the type of the solenoid valve 5 as the specifications of the newly assembled fluid pressure driven valve 1C. In this case, the candidate extraction unit 72 may extract candidates for components that the specification receiving unit 71 has not received as specifications.

[0175] In the above embodiment, the assembly condition presentation device 7 has been described as including the specification receiving unit 71, the candidate extracting unit 72, the reference data acquiring unit 73, the judgment target data acquiring unit 74, the property determining unit 75, and the information presenting unit 76. In contrast, the assembly condition presentation device 7 may be configured not to include the reference data acquiring unit 73, the judgment target data acquiring unit 74, and the property determining unit 75. In this case, it is sufficient that at least the property reference data is registered in the database 2 for each combination of the use environment 10, the main valve 3, the drive unit 4, and the solenoid valve 5.

[0176] In the above embodiment, the assembly condition presentation device 7 has been described as determining the properties of the fluid pressure driven valve 1 by referring to the database 2 (FIGS. 7 and 13) in which the judgment criterion data and property reference data are registered for each combination. In contrast, the assembly condition presentation device 7 may determine the properties of the fluid pressure driven valve 1 without referring to such a database 2. In this case, the storage unit 70 of the assembly condition presentation device 7 stores, for example, judgment criterion data and property reference data corresponding to a specific combination, and when the judgment target data acquisition unit 74 determines a newly assembled fluid pressure driven valve 1 (corresponding to a specific combination) as a judgment target for assembly inspection, it acquires, as judgment target data, an operating state when an opening / closing operation is performed on the fluid pressure driven valve 1, and the property determination unit 75 compares the judgment criterion data with the judgment target data and determines the properties of the fluid pressure driven valve to be determined based on the comparison result and the property reference data.

Also, the present invention can be provided in the form of a program (assembly condition presentation program) 230 that causes the computer 200 shown in Fig. 4 to function as each unit included in the assembly condition presentation device 7 according to the above embodiment.
