Description

  The present invention relates to a control valve characteristic information management device that acquires and manages characteristic information of a control valve set in a positioner.

  Conventionally, in a control valve opening control system that controls the opening of a control valve, a positioner is attached to the control valve to control the opening of the control valve. In this control valve opening control system, the control valve has a valve and an operating device for driving the valve, and the positioner uses air pressure corresponding to the difference between the actual opening of the valve and the set opening as an operating device. To control the opening of the valve.

  In such a control valve opening control system, the control valve and the positioner are used in combination, but they are not integrated and are often independent devices. Some positioner functions require information on the characteristics of the control valve to be combined, such as the specifications of the control valve. In recent years, as the function of the positioner, such as abnormality diagnosis, becomes more sophisticated, the required control valve characteristics Information is also increasing.

  For example, in the positioner (valve positioner) disclosed in Patent Document 1, specification data (for example, valve capacity, valve spring range, valve value) of a control valve to be combined through a man-machine interface such as a keyboard or a button. The hysteresis and the supply pressure to the operating device) are manually input to the positioner as characteristic information of the control valve.

  In this case, the positioner reads the control parameters corresponding to the specification data from the specification data (characteristic information) of the control valve input via the man-machine interface, and sets it in the valve control calculation unit. For example, values of control parameters used for valve opening control such as proportional gain, integration time, and derivative time are read from the database and set in the valve control calculation unit.

  The control valve and the positioner are often purchased and combined from different vendors, and there is almost no information on which control valve is combined with the positioner at the time of shipment. For this reason, it is difficult to obtain characteristic information of the control valve to be combined at the time of shipment of the positioner and to preset a parameter value corresponding to the characteristic information in the positioner.

  For this reason, in Patent Document 1, when the control valve and the positioner are combined, the specification data (characteristic information) of the control valve is manually transmitted to the positioner via a man-machine interface such as a keyboard and buttons. I am trying to input it. For example, the handy communicator is used to manually input the control valve characteristic information one by one. For this reason, the input operation of the characteristic information of the control valve becomes complicated and takes much time.

  The input of the characteristic information of the control valve to the positioner can also be performed using a device management system or the like. However, since the characteristic information of the control valve varies, and the characteristic information of the required control valve varies depending on the positioner (model / model), it is often impossible to set all at once even if the device management system is used. However, the problem of time-consuming input remains.

  Even if there is a database that collectively manages the characteristic information of many control valves, the device management system or the like cannot link the positioner to the control valve. Therefore, the operation of referring to the characteristic information of the control valve combined with each positioner from the instrumentation information and inputting it to the positioner occurs, and it still takes time to input.

Moreover, it is not only time-consuming, but also confirms the control valve to be combined (arrow (1) shown in FIG. 9), reads the characteristic information of the confirmed control valve from the database (arrow (2) shown in FIG. 9), since the work will leave inputting the characteristic information of the read control valve positioner (arrow shown in FIG. 9 (3)) is carried out manually, it is likely that human error will occur.

  Therefore, the applicant of the present invention reduces the effort of inputting the control valve characteristic information to the positioner and reduces the possibility of occurrence of a human error, as shown in FIG. A control system was previously proposed (Patent Document 2).

  In FIG. 10, 1 is a control valve, 2 is a positioner mounted on the control valve 1, and the control valve 1 and the positioner 2 constitute a control valve opening control system 100. In this control valve opening control system 100, the control valve 1 includes a valve (valve) 11 that opens and closes a passage through which a fluid flows, and an operating device 12 that receives the air pressure Pout and drives the valve 11. The control valve 1 also includes a control valve characteristic information holding unit 13 that holds characteristic information of the control valve 1.

  In the control valve 1, the control valve characteristic information holding unit 13 holds the characteristic information of the control valve 1 so as to be readable. For example, the valve type (Type), the operation direction (Direction), the valve diameter (Size), etc. are stored as the control valve 1 characteristic information together with the control valve 1 model number (valve model number), etc. The portion 13 is held so as to be readable.

  The positioner 2 includes a control valve characteristic information reading unit 22 and an information conversion setting unit 23 in addition to the valve control calculation unit 21. In the positioner 2, the valve control calculation unit 21 inputs the actual opening θpv of the valve 11 of the control valve 1 and the set opening θsp from the host device (not shown), and the actual opening θpv and the set opening An air pressure Pout corresponding to the difference from θsp is generated and applied to the operating device 12 of the control valve 1. Thereby, the opening degree of the valve 11 is controlled so that θpv = θsp.

  In the positioner 2, the control valve characteristic information reading unit 22 receives a reading start command sent from the outside and starts reading the characteristic information of the control valve 1 held in the control valve characteristic information holding unit 13. For example, when a read start command is sent from the host device as an operation command from the operator, the control valve characteristic information reading unit 22 accesses the control valve characteristic information holding unit 13 in response to the read start command, and the adjustment is performed. Reading of the characteristic information of the valve 1 is started.

The characteristic information of the control valve 1 read by the control valve characteristic information reading unit 22 is sent to the information conversion setting unit 23. The information conversion setting unit 23 uses the characteristic information of the control valve 1 sent from the control valve characteristic information reading unit 22, that is, the characteristic information of the control valve 1 read by the control valve characteristic information reading unit 22 as this characteristic information. The corresponding parameter value (proportional gain, integral time, derivative time, etc.) is converted and set in the valve control calculation unit 21.

  In this manner, in this control valve opening control system 100, the control valve characteristic information holding unit is simply installed by attaching the positioner 2 to the control valve 1 and sending a reading start command to the control valve characteristic information reading unit 22 of the positioner 2. The characteristic information of the control valve 1 from 13 (setting of the characteristic information of the control valve 1 to the positioner 2), the conversion of the read characteristic information into the parameter value, and the setting of the converted parameter value are automatically performed. It will be a thing.

  In addition, as a method of reading the characteristic information of the control valve 1 from the control valve characteristic information holding unit 13, a method of reading the characteristic information of the control valve 1 via a communication line (a method of reading by wired communication), or a control valve by wireless communication Various methods such as a method of reading the characteristic information of 1 and a method of reading the characteristic information of the control valve 1 in an optical non-contact manner are employed. In addition, when a large-scale plant is assumed, such a control valve opening control system 100 is installed in various places in the plant.

JP 2001-142505 A (Patent No. 3724289) Japanese Patent Application No. 2013-051416 JP 2014-134918 A

  The control valve opening control system 100 described above is excellent in that it can reduce the labor of inputting the characteristic information of the control valve 1 to the positioner 2 and can reduce the possibility of human error.

  However, if the characteristic information of the control valve 1 is not correctly registered in the control valve characteristic information holding unit 13, an appropriate parameter value is not set in the valve control calculation unit 21, and trouble may occur. In addition, when automatic reading of the characteristic information of the control valve 1 from the control valve characteristic information holding unit 13, even when an error occurs in the reading, an appropriate parameter value is not set in the valve control calculation unit 21, Trouble may occur.

  In Patent Document 3, when it is instructed to display history information of parameter information corresponding to one device among a plurality of devices displayed in a list, the same group as the instructed one device 1 shows a device management apparatus that extracts parameter information of devices belonging to the device from stored parameter information and displays the extracted parameter information of devices belonging to the same group on the screen.

  When the technology disclosed in Patent Document 3 is applied to the management of control valve characteristic information, the control valve characteristic information set for the positioner is obtained from the positioners attached to the control valves. When a plurality of control valves that have acquired the characteristic information are displayed in a list, and the characteristic information of one control valve is designated from among the plurality of control valves displayed in the list, the designated control valve and It is conceivable to extract characteristic information of control valves belonging to the same group from stored characteristic information and display the extracted characteristic information of control valves belonging to the same group on the screen.

  However, this method is convenient for picking up and comparing and confirming the characteristics information of some control valves that should be handled as one group from the acquired characteristics information of multiple control valves. In order to check whether or not the valve characteristic information has been correctly read from the control valve and whether it has been registered correctly in the control valve, it is necessary to select and display several times for each group. is there. That is, for example, when the control valves of the same model number are grouped into one group, different control valves must be selected for each model number, and the characteristic information of the control valve of the same model number must be displayed on the screen one by one.

  Further, in the method of simply displaying a list of characteristic information of all the control valves, the operator must understand which control valves are to be compared and confirmed, and cannot be used by an operator with a low level of proficiency.

  The present invention has been made in order to solve such problems, and the object of the present invention is to have a problem among the characteristic information of all the control valves acquired even by an operator having a low level of proficiency. An object of the present invention is to provide a control valve characteristic information management device capable of quickly extracting and confirming control valve characteristic information.

In order to achieve such an object, the present invention uses a plurality of control valves as management targets, and obtains characteristic information of the control valves set in the positioners from the positioners attached to the control valves. A control valve characteristic information management device that acquires and manages a control valve characteristic information acquisition unit that acquires characteristic information of a control valve set in the positioner from each positioner together with key information indicating a group to which the control valve belongs. And a group identification information registration storage unit for storing group identification information registered in advance as identification information used when grouping the control valves, and characteristic information of all the control valves acquired by the control valve characteristic information acquisition unit The characteristic information of all the control valves that are the targets is shared with the group identification information registered in the group identification information registration storage unit and the characteristic information of the control valves. Grouped on the basis of the acquired key information, listing the characteristics information of the regulating valve to which the grouping for each group, on the display unit collectively characteristic information of the regulating valve of all groups that this listing And a display processing unit for displaying.

For example, in the present invention, the registered group identification information is used as the control valve model number information, and the key information indicating the group to which the control valve belongs together with the control valve characteristic information acquired from each positioner includes the control valve model number information. If all the control valve characteristics information obtained from each positioner is grouped by control valve model number, the control valve characteristic information grouped by model number is listed by model number. The characteristic information of the control valves of all the groups listed is collectively displayed on the display unit.

  Thus, the operator can easily compare and confirm the characteristic information of the control valve of the same model number on the screen for each control valve of the same model number. That is, since it is considered that the characteristic information of the control valve of the same model number must be the same, all the acquired information is obtained by comparing the characteristic information of the control valve of the same model number and checking whether there is a discrepancy. It is possible to quickly extract and confirm the characteristic information of the problematic control valve from the characteristic information of the control valve.

  In the present invention, when the display processing unit compares the characteristic information of the control valves belonging to the same group, and the number of characteristic information different from other characteristic information is equal to or less than the number of other characteristic information, the characteristic information May be provided with a function of performing processing for displaying on the display unit in a display form different from other characteristic information. In this way, depending on the display form of the characteristic information of the control valve, it is possible to visually and quickly identify and identify the characteristic information of the problematic control valve, such as the possibility of failure of the reading process.

  Further, in the present invention, information on whether or not the characteristic information has been manually changed is obtained together with the characteristic information of the control valve set in the positioner from each of the positioners, and the control valve characteristic is displayed in the display processing unit. When the characteristic information of the control valve acquired by the information acquisition unit has been manually changed in the positioner, a function of displaying the characteristic information separately from the characteristic information of other control valves may be provided.

  In this way, if the characteristic information of the control valve is different from the characteristic information of other control valves in the same group as a result of manual change, the operator is warned that the characteristic information is not abnormal. It becomes possible. In this case, the date and time of the manual change may be included in the information on whether or not the manual change has been made.

  Further, in the present invention, the date and time when the characteristic information is set together with the characteristic information of the control valve set for the positioner is obtained from each positioner, and the characteristics of the control valves belonging to the same group are obtained in the display processing unit. When the set date / time in which information is set is compared in the set date / time range to which each date / time belongs, and the number of set date / time ranges different from other set date / time ranges is less than or equal to the other set date / time ranges, the set date / time A function for displaying the set date and time belonging to the range on the display unit in a display form different from the set date and time belonging to another set date and time range may be provided.

  In this way, for example, for each group where the date and time of automatic reading of the characteristic information of the control valve (automatic setting of the characteristic information of the control valve to the positioner) should be the same, such as for each area where the control valve is installed When the characteristic information of the control valve is displayed, the presence and identification of the characteristic information of the problematic control valve can be quickly and visually determined by the display format of the date and time when the characteristic information of the control valve is set. Become.

In the present invention, the group identification information to be registered is not limited to the model number information of the control valve, and may be area information where the control valve is installed. For example, in the present invention, the registered group identification information is set as area information where the control valve is installed, and the control valve is included in the key information indicating the group to which the control valve belongs together with the control valve characteristic information acquired from each positioner. Assuming that the installed area information was included, the characteristic information of all control valves acquired from each positioner was grouped for each area where control valves were installed, and grouped for each area. The characteristic information of the control valves thus created is listed for each area, and the characteristic information of the control valves of all the listed groups is displayed on the display unit collectively.

Further, in the present invention, the characteristic information of the control valves divided into groups is listed for each group, and the characteristic information of the control valves of all the groups listed is collectively displayed on the display unit. If it does not fit, it may be displayed in a scrollable manner on the screen. In some cases, it is divided into a plurality of pages for display. Such a display form also corresponds to the collective display in the present invention.

According to the present invention, the characteristic information of the control valve set in the positioner is acquired from each positioner together with the key information indicating the group to which the control valve belongs, and the acquired characteristic information of all the control valves is registered in advance. Grouped based on the group identification information and the key information acquired together with the control valve characteristic information, and the grouped control valve characteristic information is listed for each group. Because the characteristic information of all control valves is displayed at once, even the less skilled operator can quickly extract the characteristic information of the problematic control valve from all the acquired control valve characteristic information Can be confirmed.

  Further, in the present invention, when the characteristic information of the control valves belonging to the same group is compared, and the number of characteristic information different from the other characteristic information is equal to or less than the other characteristic information, the characteristic information is Presence and identification of problematic control valve characteristic information such as the possibility of reading processing failure depending on the control valve characteristic information display form if displayed on the display unit in a display form different from the characteristic information Can be made visually quick.

  Further, in the present invention, the control valve characteristic information acquisition unit acquires information on whether or not the characteristic information has been changed manually together with the characteristic information of the control valve set to the positioner from each positioner. If the characteristic information of the control valve was changed manually in the positioner, the characteristic information is displayed separately from the characteristic information of other control valves. If the characteristic information is different from the characteristic information of other control valves in the same group, the operator can be alerted that the characteristic information is not abnormal.

  Further, in the present invention, the date and time when the characteristic information is set together with the characteristic information of the control valve set in the positioner is acquired from each positioner, and the characteristic information of the control valves belonging to the same group is set. When the set date / time range is compared with the set date / time range to which each date / time belongs, and the number of set date / time ranges different from other set date / time ranges is less than or equal to the other set date / time ranges, the set date / time belonging to the set date / time range Is displayed on the display unit in a display form different from the set date and time belonging to other set date and time ranges, for example, the date and time of automatic reading of the control valve characteristic information is the same, for example, for each area where the control valve is installed If the control valve characteristic information is displayed for each group that should be, the characteristics of the problematic control valve may vary depending on the date and time display format of the control valve characteristic information. It is possible to perform visual quickly presence and specific information.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a main part of a system including an embodiment of a control valve characteristic information management device according to the present invention.

  In FIG. 1, 1 is a control valve, 2 is a positioner attached to the control valve 1, and a combination of the control valve 1 and the positioner 2 is provided as a control valve opening degree control system 100 in various parts of a large-scale plant. ing. Since the configuration of the control valve opening control system 100 combining the control valve 1 and the positioner 2 is the same as that shown in FIG. 10, the description thereof is omitted here.

  In the present embodiment, a control valve opening control system 100 (a combination of control valves 1 (1-1 to 1-n) and positioners 2 (2-1 to 2-n) provided at various locations in the plant. 100-1 to 100-n) is provided with a device management system 3. This equipment management system 3 corresponds to a control valve characteristic information management apparatus according to the present invention. The device management system 3 is realized by hardware including a processor and a storage device, and a program that realizes various functions in cooperation with the hardware.

In this embodiment, the device management system 3 obtains the characteristic information of the control valve 1 set in the positioner 2 from each of the positioners 2 (in this example, the characteristic information automatically read from the control valve 1). A control valve characteristic information acquisition unit 31 that is acquired together with key information indicating a group to which the control valve 1 belongs, and a group that stores pre-registered group identification information as identification information used when grouping the control valves 1 in the plant. The identification information registration storage unit 32 and the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31 are the targets, and the characteristic information of all the control valves 1 that are the targets are the group identification information registration storage unit Grouped based on the group identification information registered in the key No. 32 and the key information acquired together with the characteristic information of the control valve 1, and the grouped control valves A display processing section 33 of the characteristic information in a lump into a list for each group of (collectively the characteristic information of the regulating valve 1 of all groups were listed) is displayed on the display unit 34, a display unit such as a liquid crystal display 34.

[Embodiment 1: Example of grouping based on model number information]
In a large-scale plant, there is a high possibility that a plurality of control valves 1 of the same type are installed. Moreover, the characteristic information of the control valve 1 is highly likely to be the same depending on the model number.

  Focusing on this point, in the first embodiment, the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31 is grouped based on the model number (model number information) of the control valve 1, The grouped characteristic information of the control valve 1 is listed for each group and displayed on the display unit 34 at a time.

  FIG. 2 illustrates information acquired from each of the positioners 2 by the control valve characteristic information acquisition unit 31 in the first embodiment. In the first embodiment, the control valve characteristic information acquisition unit 31 sets the valve type (Type), the operation direction (Direction), and the valve diameter (Size) as the characteristic information of the control valve 1 set in the positioner 2. get. Further, together with the characteristic information of the control valve 1, the identifier of the positioner 2 (positioner identifier) and the model number (valve model number) of the control valve 1 are acquired. Information acquired from each of the positioners 2 by the control valve characteristic information acquisition unit 31 is stored in the database DB.

  In the first embodiment, among the information acquired by the control valve characteristic information acquisition unit 31, the model number of the control valve 1 is used as key information indicating a group to which the control valve 1 belongs. In the first embodiment, the characteristic information of the control valve 1 is regarded as the same if the model numbers are the same, and is used as identification information (group identification information) used when grouping the control valves 1 in the plant. The model number of the control valve 1 used in the plant is registered and stored in the group identification information registration storage unit 32.

  Even if the model numbers are different, the characteristic information may be the same, so the model number of the control valve 1 may not be the group identification information registered in the group identification information registration storage unit 32 as it is. For example, group identification information may be registered with a combination of model numbers having the same characteristic information. In the first embodiment, in order to simplify the explanation, all kinds of model numbers of the control valve 1 used in the plant are simply used as group identification information.

  In the first embodiment, when the display processing unit 33 receives an operation command (characteristic information reading confirmation command) for reading the characteristic information from the operator, the display processing unit 33 instructs the control valve characteristic information acquisition unit 31 to acquire the characteristic information of the control valve. Send.

  Upon receiving this control valve characteristic information acquisition command, the control valve characteristic information acquisition unit 31 receives the characteristic information of the control valve 1 set in the positioner 2 from each positioner 2 in the plant, and the positioner 2 Information including the model number of the mounted control valve 1 and the identifier (positioner identifier) of the positioner 2 is acquired and stored in the database DB. FIG. 2 illustrates information acquired by the control valve characteristic information acquisition unit 31 at this time.

  Before receiving the characteristic information reading confirmation command, each positioner 2 receives the characteristic information reading start command from the operator, and automatically reads the characteristic information of the mounted control valve 1 (control valve to the positioner 2). 1) (automatic setting of characteristic information).

  Next, the display processing unit 33 targets the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31 stored in the database DB, and the characteristics of all the control valves 1 that are the targets. The information is grouped based on the group identification information (model number) registered in the group identification information registration storage unit 32 and the key information (model number) acquired together with the characteristic information of the control valve 1, and the grouped control valves 1 characteristic information is listed for each group (for each model number) and displayed on the display unit 34 in a lump. In this grouping, the display processing unit 33 treats the positioner identifier as information added to the characteristic information of the control valve 1 among the information acquired by the control valve characteristic information acquisition unit 31.

  FIG. 3 shows a display example of the characteristic information of the control valve 1 grouped and listed for each model number in the display unit 34. In this example, the display processing unit 33 groups the characteristic information of all the control valves 1 including the positioner identifier acquired by the control valve characteristic information acquisition unit 31 by the valve model numbers A, B, C, and D, and the grouping is performed. The characteristic information of the control valve 1 is listed for each valve model number A, B, C, D, and displayed on the display unit 34 at once.

  Thereby, the operator can easily compare and confirm the characteristic information of the control valve 1 of the same model number for each control valve 1 of the same model number on the screen of the display unit 34. That is, in this example, the characteristic information of the control valve 1 of the same model number must be the same, but if the number of characteristic information different from other characteristic information is equal to or less than the other characteristic information, the characteristic information is It can be seen that there is a possibility that the reading is not normally performed from the control valve 1 or that it is not correctly registered in the control valve 1.

  In the example of FIG. 3, the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0003” of the valve model number A is different from the characteristic information of the other three control valves 1 of the same model number. Accordingly, there is a possibility that the characteristic information of the control valve 1 with the positioner identifier “YYY.AVP.0003” is not normally read from the control valve 1 or is not correctly registered in the control valve 1. I understand that.

  In the example of FIG. 3, the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0003” of the model number A is different from the others by changing the color of its display area. They are displayed separately. In this case, the display processing unit 33 compares the characteristic information of the control valves 1 belonging to the same group, and when the number of characteristic information different from the other characteristic information is equal to or less than the other characteristic information, the characteristic The information is displayed on the display unit 34 in a display form different from other characteristic information.

  As shown in FIG. 4, for example, when there are two control valves 1 of the valve model number C and the characteristic information of the two control valves 1 is different, that is, different adjustments are made between the control valves 1 of the same model number. When the number of characteristic information of the valve 1 is the same, it is not known which is the problem. Therefore, it is considered that the characteristic information of either of the control valves 1 may have a problem. Different display formats such as changing the display color of information are displayed.

  In this way, in the first embodiment, the operator is a low-skilled operator by viewing the characteristic information of the control valve 1 displayed in a list for each group (for each model number) on the display unit 34. However, the characteristic information of the problematic control valve 1 can be quickly extracted and confirmed from the acquired characteristic information of all the control valves 1. In addition, when the number of characteristic information different from other characteristic information is equal to or less than the number of other characteristic information in the characteristic information of the control valve 1 of the same model number, the characteristic information is different from the other characteristic information. Since it is displayed in different display forms, the existence and specification of the characteristic information of the problematic control valve 1 can be quickly performed visually.

[Embodiment 2: Example of grouping based on area information]
In a large-scale plant, a plurality of control valves 1 may be installed in divided areas. Moreover, when the some control valve 1 is divided and installed in an area, the installation time of the control valve 1 may differ for every area.

  Focusing on this point, in the second embodiment, the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31 is based on the area (area information) where the control valves 1 are installed. The characteristics information of the grouped control valves 1 is listed for each group and displayed on the display unit 34 at once.

  FIG. 5 illustrates information acquired from each of the positioners 2 by the control valve characteristic information acquisition unit 31 in the second embodiment. In the second embodiment, the control valve characteristic information acquisition unit 31 sets the valve type (Type), the operation direction (Direction), and the valve diameter (Size) as the characteristic information of the control valve 1 set in the positioner 2. get. In addition to the characteristic information of the control valve 1, the identifier of the positioner 2 (positioner identifier), the area where the control valve 1 is installed (plant area), and the characteristic information of the control valve 1 are set in the positioner 2. The date and time (the date and time when the characteristic information of the control valve 1 was automatically read) is acquired. Information acquired from each of the positioners 2 by the control valve characteristic information acquisition unit 31 is stored in the database DB.

  Moreover, in Embodiment 2, the area where the control valve 1 is installed among the information which the control valve characteristic information acquisition part 31 acquires is used as key information which shows the group to which the control valve 1 belongs. In the second embodiment, if the area where the control valve 1 is installed is the same, the setting date and time (adjustment of the characteristic information of the control valve 1 to the positioner 2 mounted on the control valve 1 in the area) The date and time when the characteristic information of the valve 1 is automatically read) are regarded as the same, and the control valve 1 in the plant is used as identification information (group identification information) used when grouping the control valves 1 in the plant. Is registered in the group identification information registration storage unit 32 and stored.

  In the second embodiment, when the display processing unit 33 receives an operation command (characteristic information reading confirmation command) for reading confirmation of the characteristic information from the operator, the display processing unit 33 instructs the control valve characteristic information acquisition unit 31 to acquire the characteristic information of the control valve. Send.

  Upon receiving this control valve characteristic information acquisition command, the control valve characteristic information acquisition unit 31 receives the characteristic information of the control valve 1 set in the positioner 2 from each positioner 2 in the plant, and the positioner 2 Information including the area where the mounted control valve 1 is installed, the date and time when the characteristic information of the control valve 1 is set in the positioner 2, and the identifier (positioner identifier) of the positioner 2 is acquired, and the database Store in DB. FIG. 5 illustrates information acquired by the control valve characteristic information acquisition unit 31 at this time.

  Before receiving the characteristic information reading confirmation command, each positioner 2 receives the characteristic information reading start command from the operator, and automatically reads the characteristic information of the mounted control valve 1 (control valve to the positioner 2). 1) (automatic setting of characteristic information).

  Next, the display processing unit 33 targets the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31 stored in the database DB, and the characteristics of all the control valves 1 that are the targets. The information is grouped based on the group identification information (area) stored in the group identification information registration storage unit 32 and the key information (area) acquired together with the characteristic information of the control valve 1, and the grouped control valves The one characteristic information is listed for each group (for each area) and displayed on the display unit 34 in a lump. In this grouping, the display processing unit 33 adds the date and time when the positioner identifier and the characteristic information of the control valve 1 among the information acquired by the control valve characteristic information acquisition unit 31 are set to the characteristic information of the control valve 1. Information.

  FIG. 6 shows a display example of the characteristic information of the control valve 1 grouped for each area in the display unit 34 and listed. In this example, the display processing unit 33 displays the characteristic information of all the control valves 1 including the date and time when the positioner identifier acquired by the control valve characteristic information acquisition unit 31 and the characteristic information of the control valve 1 are set in the plant areas AR1, AR2. The characteristic information of the control valve 1 thus grouped is listed for each of the plant areas AR1 and AR2, and is collectively displayed on the display unit 34.

  Thus, the operator can easily compare and confirm the characteristic information of the control valve 1 in the same area for each control valve 1 installed in the same area on the screen of the display unit 34. That is, in this example, the setting date / time of the characteristic information of the control valve 1 installed in the same area must be the same, but the setting date / time of the characteristic information of the control valve 1 installed in the same area is When the number of setting date / time ranges different from other setting date / time ranges is equal to or less than the number of other setting date / time ranges, the characteristic information to which the setting date / time is added is the control valve 1. It can be seen that there is a possibility that the data is not read correctly or is not correctly registered in the control valve 1.

  In the example of FIG. 6, the setting date / time of the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0001” in the plant area AR1 is significantly different from the setting date / time of the characteristic information of the other five control valves 1 in the same area. ing. As a result, there is a possibility that the characteristic information of the control valve 1 with the positioner identifier “YYY.AVP.0001” is not normally read from the control valve 1 or is not correctly registered in the control valve 1. I understand that.

  In the example of FIG. 6, the setting date and time of the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0001” of the plant area AR1 is displayed separately by changing the color of the display area. Yes. In this case, the display processing unit 33 compares the set dates and times of the characteristic information of the control valves 1 belonging to the same group with the set date and time ranges to which the respective dates and times belong, and the number of set date and time ranges different from the other set date and time ranges is different. If the number is less than or equal to the set date / time range, the setting date / time belonging to the set date / time range is displayed on the display unit 34 in a display form different from the set date / time belonging to the other set date / time range.

  Further, as shown in FIG. 7, for example, when there are two control valves 1 in the area AR3 and the setting date and time of the characteristic information of the two control valves 1 are different, that is, in the control valve 1 in the same area. If the number of different setting date and time of the characteristic information is the same, it is not known which is the problem. Therefore, it is considered that the characteristic information of either control valve 1 may have a problem. Change the display form such as changing the display color of the set date and time.

  As described above, in the second embodiment, the learning level is low by viewing the characteristic information of the control valve 1 including the set date and time displayed in a list for each group (for each area) on the display unit 34. Even an operator can quickly extract and confirm the characteristic information of the problematic control valve 1 from the acquired characteristic information of all the control valves 1. If the number of set date / time ranges different from other set date / time ranges is less than or equal to the other set date / time ranges in the set date / time of the characteristic information of the control valve 1 installed in the same area Since the set date and time belonging to the date and time range is displayed in a display form different from the set date and time belonging to other set date and time ranges, the presence and identification of the characteristic information of the problematic control valve 1 can be quickly performed visually. become.

[Embodiment 3: Example of displaying manual change date and time of characteristic information of control valve]
In FIG. 1, the positioner 2 automatically reads the characteristic information from the control valve 1 in response to a characteristic information reading start command from the operator. However, the characteristic information that has been automatically read may be manually changed. is there.

  Focusing on this point, in the third embodiment, the date and time when the characteristic information is manually changed is acquired together with the characteristic information of the control valve 1, and together with the characteristic information of the control valves 1 grouped together It is displayed on the display unit 34.

  In the third embodiment, when the display processing unit 33 receives an operation command (characteristic information reading confirmation command) for confirming reading of characteristic information from the operator, the control valve characteristic information acquisition unit 31 receives an instruction for acquiring characteristic information of the control valve. Send.

  Upon receiving this control valve characteristic information acquisition command, the control valve characteristic information acquisition unit 31 receives the characteristic information of the control valve 1 set in the positioner 2 from each positioner 2 in the plant, and the positioner 2 Whether or not the model number of the mounted control valve 1, the identifier of the positioner 2 (positioner identifier), and the characteristic information of the control valve 1 set in the positioner 2 are manually changed characteristic information Information is acquired and stored in the database DB.

  In this case, as information on whether or not the characteristic information of the control valve 1 set in the positioner 2 is the characteristic information manually changed, the date and time when the characteristic information of the control valve 1 is manually changed in the positioner 2 is displayed. Shall be acquired. Of the characteristic information of the control valve 1 acquired from the positioner 2, the characteristic information to which the manually changed date and time is not added indicates that the characteristic information is automatically read.

  Next, the display processing unit 33 targets the characteristic information of all the control valves 1 acquired by the control valve characteristic information acquisition unit 31, and stores the characteristic information of all the control valves 1 that are the targets as a group identification information registration storage. Grouping is performed based on the group identification information (model number) stored in the unit 32 and the key information (model number) acquired together with the characteristic information of the control valve 1, and the characteristic information of the grouped control valve 1 is displayed for each group. A list is created for each model number and displayed on the display unit 34 in a batch. In this grouping, the display processing unit 33 adjusts the date and time when the positioner identifier and the characteristic information of the control valve 1 are manually changed among the information acquired by the control valve characteristic information acquisition unit 31 (manual change date and time). It is handled as information added to the characteristic information of the valve 1.

  FIG. 8 shows a display example of the characteristic information of the control valve 1 grouped and listed for each model number in the display unit 34. In this example, the display processing unit 33 displays the characteristic information of all the control valves 1 including the positioner identifier and manual change date and time acquired by the control valve characteristic information acquisition unit 31 stored in the database DB. The characteristic information of the control valve 1 that has been grouped is grouped by C, and is listed for each valve model number A, B, and C, and displayed together on the display unit 34. In this example, the characteristic information of the control valve 1 includes a valve type (Type), an operation direction (Direction), a valve diameter (Size), and a valve spring range (Range).

  As a result, the operator determines whether the characteristic information has been changed manually or has been automatically read for each control valve 1 installed in the same area on the screen of the display unit 34. While confirming, the characteristic information of the control valve 1 in the same area can be easily compared and confirmed. In this case, since the information on which the manual change date and time is displayed is not the characteristic information automatically read, even if the value is different from the characteristic information of the other control valve 1 of the same model number, it is not a reading abnormality. I understand that.

  In the example of FIG. 8, manual change date and time is added to the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0004” of the valve model number A. Thereby, even if the characteristic information of the control valve 1 of the positioner identifier “YYY.AVP.0004” of the valve model number A is different from the characteristic information of the other three control valves 1 of the same model number, it is considered that the reading is not abnormal. It is done. That is, it is considered that the change is intentional by the operator.

  In the example of FIG. 8, the characteristic information of the control valve 1 of the positioner identifier “XXX.AVP.00003” of the valve model number B is different from the characteristic information of the other three control valves 1 of the same model number. No manual change date / time is added to all the control valves 1 in the group. As a result, the characteristic information of the control valve 1 with the positioner identifier “XXX.AVP.00003” is not intentionally changed by the operator and is not normally read from the control valve 1 or is correctly registered in the control valve 1. It turns out that there is a possibility that it is not.

In the third embodiment, the manual change date / time is displayed. However, the manual change date / time need not necessarily be displayed, and only whether or not the manual change has been made may be displayed. Good. In other words, it may be displayed so that it can be understood whether it has been manually changed or has been automatically read.

  Moreover, although Embodiment 3 demonstrated as an example which displays a manual change date in the type of Embodiment 1, you may make it display a manual change date in the type of Embodiment 2. FIG.

  In the first embodiment, the date and time when the characteristic information of the control valve 1 is set may be displayed in the same manner as in the second embodiment. For example, when all the target control valves 1 are installed in the same area, the troubled control valve 1 can be quickly extracted by displaying the date and time when the characteristic information of the control valve 1 is set in the positioner 2. Can be confirmed.

  In the first to third embodiments described above, the characteristic information of the control valve 1 is automatically read by the positioner 2 in response to a characteristic information reading start command from the operator. The characteristic information may be set.

  In the first to third embodiments described above, the positioner 2 receives the characteristic information reading start command before the device management system 3 receives the characteristic information reading confirmation command, and the characteristic information of the mounted control valve 1 is automatically detected. Although the reading is performed, the automatic reading of the characteristic information of the control valve 1 may be started in the positioner 2 simultaneously with the characteristic information reading confirmation command to the device management system 3.
