That is, each of the above-mentioned functions of the equipment maintenance device 100 is a functional module realized by software.

The communication unit 101 controls communication with the field device 19 or communication with another device via the communication I / F 16 to acquire information on the field device 19. By the communication controlled by the communication unit 101, for example, the parameters (device information) of the field device 19 of the standard such as ISA100, HART, BRAIN are set, the parameters are read, and the parameters are confirmed.
The communication unit 101 may control wireless LAN communication, wired LAN communication, infrared communication, short-range wireless communication, and the like. The communication unit 101 may have a program module for performing control corresponding to each communication. The communication unit 101 may add and install a program module required for each communication. The communication unit 101 can automatically recognize the field device 19 connected via the communication I / F 16 and acquire the parameters of the recognized field device 19.

The acquisition of information on the field device 19 is not limited to the acquisition of information by the above-mentioned communication. For example, an operator visually confirms the tag name and model name of the field device 19 and inputs a key, or photographs the name plate of the field device 19 with the tag name and model name written by the camera provided in the device maintenance device 1. Then, the tag name and the model name may be recognized and acquired from the captured image.

The device information storage unit 102 stores device information of the field device 19 and information on maintenance items corresponding thereto. The parameters (device information) of the field device 19 stored in the device information storage unit 102 are, for example, field devices such as the device tag, device address, manufacturer, device ID or device type, model name, and communication standard of the field device 19. Information for identifying 19, or measurement data measured by the field device 19.

The maintenance items stored in the device information storage unit 102 are confirmation of parameters set in the field device 19, setting of parameters for the field device 19, predetermined test, predetermined adjustment, and the like. The maintenance item may include the output of a report for reporting the implementation result of the maintenance item.

The device information storage unit 102 associates each field device 19 with a maintenance item executed in the field device 19 and stores the associated information in a readable manner. The device information storage unit 102 can associate one or more maintenance items with one field device 19. Among the above maintenance items, there are maintenance items that can be executed and maintenance items that cannot be executed in the predetermined field device 19. For example, a valve calibration maintenance item can be performed on a field device 19 that has a valve, but not on a field device 19 such as a thermometer that does not have a valve. The device information storage unit 102 stores maintenance items that can be executed in each field device 19 in association with the field device 19. The association between the device information of the field device 19 and the maintenance item can be performed, for example, based on a setting file in which correspondence is set in advance. In the setting file, for example, information such as a device type and a communication standard may be associated with maintenance items. Further, the association between the field device 19 and the maintenance item may be arbitrarily set by the operator. The association between the field device 19 and the maintenance item may be set by the device information setting unit 104.

In the field device 19, the maintenance items may not be associated (0 maintenance items are associated). For example, for the field equipment 19 that is out of order or not in use, it can be shown that the maintenance work is unnecessary by storing the fact that the maintenance items are not associated with each other. The device information storage unit 102 may store the associated information in, for example, the HDD 14.

The maintenance item identification unit 103 selects maintenance items to be displayed on the touch panel 15 from the maintenance items stored in the device information storage unit 102 based on the device information (also referred to as “parameter”) acquired by the communication unit 101. Identify. For example, when five maintenance items are associated with one field device 19 in the device information storage unit 102, the maintenance item identification unit 103 has three of the five associated maintenance items. Identify maintenance items. The details of the method for identifying the maintenance item will be described with reference to FIG. The maintenance item specifying unit 103 outputs the specified maintenance item to the display data generation unit 105.

The device information setting unit 104 provides a UI (User Interface) for setting parameters and maintenance items of the field device 19 stored in the device information storage unit 102.
For example, the device information setting unit 104 acquires information on the parameters of the field device 19 and maintenance items in advance via the communication I / F 16. The device information setting unit 104 displays the acquired parameters of the field device 19 and the maintenance item information on the touch panel 15 so that the association between the field device 19 and the maintenance item can be set. The device information setting unit 104 may output the set correspondence to the device information storage unit 102.

The display data generation unit 105 generates display data for displaying the parameters of the field device 19 acquired by communication connection by the communication unit 101 on the touch panel 15. Further, the display data generation unit 105 generates display data for displaying the maintenance items specified by the maintenance item identification unit 103 together with the parameters of the field equipment 19 in correspondence with the parameters of the displayed field equipment 19. For example, on the touch panel 15, maintenance items are displayed in association with parameters of the field device 19. Further, when a plurality of field devices 19 are displayed, maintenance items may be displayed for each field device 19. It should be noted that "generating display data for display" may be abbreviated as "displaying". Further, the display data generation unit 105 may be expressed as a display unit. That is, the display unit in the present embodiment may be a display device such as the touch panel 15, or may generate display data displayed on the display device.

In addition, the display data generation unit 105 generates data for displaying an execution button for executing the specified maintenance item for the connected field device 19. The execution button is an operation target displayed on the touch panel 15 and is an embodiment of the “operation unit”. The maintenance item is executed by operating the execute button. The execute button is displayed in the form of, for example, a figure, a character, an icon, a symbol, or the like. The operator can execute the maintenance item by operating the execution button displayed on the touch panel 15. Note that FIG. 4 illustrates an execution button having a rectangular area in which characters are displayed. The operator can execute the maintenance item by touching the area of the rectangular operation portion of the touch panel 15.
The execute button may be an item selected by the pull-down menu.

Further, the display data generation unit 105 may display information regarding the execution button of the maintenance item to be displayed. For example, the display data generation unit 105 displays the execution button and the past execution result of the maintenance item executed by the execution button.

The maintenance execution unit 106 executes a maintenance item displayed by the display data generation unit 105 and operated by an operator (for example, pressing a button). The maintenance item is executed for each maintenance item operated. For example, when one maintenance item is operated, one maintenance item is executed. The maintenance execution unit 106 sets maintenance items, displays the progress of maintenance items, displays the execution result of maintenance items, and the like.

The maintenance information storage unit 107 stores the results of maintenance items executed by the maintenance execution unit 106.
The result of the maintenance item is, for example, the execution date and time of the maintenance item, the execution result of the maintenance item, the maintenance plan based on the execution result of the maintenance item, and the like. The results of the maintenance items saved in the maintenance information storage unit 107 are obtained from, for example, the maintenance item identification unit 103, the maintenance execution unit 106, and the like.

In FIG. 2, the communication unit 101, the equipment information storage unit 102, the maintenance item identification unit 103, the equipment information setting unit 104, the display data generation unit 105, the maintenance execution unit 106, and the maintenance information included in the equipment maintenance device 10. The case where each function of the storage unit 107 is realized by software has been described. However, one or more of the above-mentioned functions of the equipment maintenance device 10 may be realized by hardware. Further, each of the above-mentioned functions of the equipment maintenance device 10 may be performed by dividing one function into a plurality of functions. Further, each of the above-mentioned functions of the equipment maintenance device 10 may be implemented by consolidating two or more functions into one function.
This completes the description of the functional configuration of the equipment maintenance device 100 using FIG.

Next, the operation of the equipment maintenance device 10 will be described with reference to FIG. FIG. 3 is a flowchart showing an example of the operation of the equipment maintenance device 10 in the embodiment. The operation of the equipment maintenance device 10 described with reference to FIG. 3 can be carried out, for example, by the CPU 11 of the equipment maintenance device 10 to execute each function described with reference to FIG. In the following description, FIGS. 1 and 2 will be referred to as appropriate.

In FIG. 3, the equipment maintenance device 10 executes the communication connection process (step S11). The communication connection process is executed by the communication unit 101 communicating with the field device 19 connected to the communication I / F 16 via a predetermined protocol. For example, the device maintenance device 10 connects to the field device 19 at a predetermined device address via a predetermined communication protocol.

After executing the process of step S11, the equipment maintenance device 10 acquires the parameter (equipment information) from the connected field equipment 19 (step S12). The acquisition of the parameters from the field device 19 is executed by the communication unit 101. For example, when there are two field devices 19 connected in step S11, the communication unit 101 acquires parameters from each of the two field devices 19. In steps S11 to S12, the parameter acquisition is shown in the case where the parameter is acquired by communication from the field device 19 connected via the communication I / F 16, but the parameter acquisition is, for example, the device maintenance device 1. It may be acquired by a method other than communication, such as a camera and a microphone provided in the device.

After executing the process of step S12, the equipment maintenance device 10 searches for maintenance items (step S13). The search for the maintenance item can be executed by the maintenance item identification unit 103. The search for the maintenance item is performed based on the parameters of the field device 19 acquired in step S12, using the information associated with the field device 19 stored in the device information storage unit 102 and the maintenance item. For example, when the parameters of the field devices 19 for two devices are acquired in step S12, the device maintenance device 10 searches for maintenance items corresponding to the parameters of the field devices 19 for the two devices, and for the two devices. Get search results.

After executing the process of step S13, the equipment maintenance device 10 specifies a maintenance item to be displayed as an execution button on the touch panel 15 (step S14). The identification of the maintenance item in step S14 is, for example, a determination of whether or not to display the execution button of the specified maintenance item on the touch panel 15. Further, the maintenance items may be specified to determine the display order of the execution buttons displayed on the touch panel 15. Here, a method for identifying maintenance items will be described. The method for specifying the maintenance items illustrated below can be carried out by any one or a combination of two or more.

[Specification of maintenance items by optional settings of workers]
The maintenance items in the process of step S14 are specified based on the settings arbitrarily set by the operator in advance. For example, the operator selects one field device 19 displayed on the touch panel 15, and selects the execution button displayed corresponding to the selected field device 19 from the maintenance item selection screen displayed on the touch panel 15. To do. The selected maintenance item is stored in, for example, the device information storage unit 102. The maintenance item specifying unit 103 specifies the maintenance item to be displayed as an execution button on the touch panel 15 according to the stored maintenance item. The method for specifying this maintenance item will be described later with reference to FIG.

[Identification of maintenance items based on the implementation results of maintenance items]
The maintenance item in the process of step S14 is specified based on the execution result of the maintenance item. For example, the maintenance item for which an abnormality was found in the previous implementation of the maintenance item is stored in the device information storage unit 102. The maintenance item specifying unit 103 specifies the maintenance item to be displayed as an execution button on the touch panel 15 based on the maintenance item in which the stored abnormality is found.

[Identification of maintenance items based on the implementation frequency of maintenance items]
As another example of executing the identification of the maintenance item in the process of step S14 based on the execution result of the maintenance item, it is executed based on the execution frequency of the maintenance item. For example, maintenance items often performed by workers are stored in the device information storage unit 102. Frequently performed maintenance items may be determined, for example, by the number of times they have been performed in the past few months based on the results of the maintenance items. The maintenance item specifying unit 103 specifies a maintenance item to be displayed as an execution button on the touch panel 15 based on the stored well-performed maintenance items.

[Identification of maintenance items based on the maintenance item implementation plan]
The maintenance item in the process of step S14 is specified based on the maintenance item implementation plan. For example, when an implementation plan (maintenance plan) for maintenance items has been created in advance, the maintenance plan is stored in the equipment information storage unit 102. The maintenance item specifying unit 103 specifies the maintenance item to be displayed as an execution button on the touch panel 15 based on the stored maintenance plan. The maintenance items performed may be excluded from the specific target.

After executing the process of step S14, the equipment maintenance device 10 displays the parameters of the field equipment 19 acquired in step S12 on the touch panel 15 (step S15). The parameters of the field device 19 displayed on the touch panel 15 in the process of step S15 are, for example, basic information such as the device tag of the field device 19, device ID, and measurement data acquired from the field device 19.

After executing the process of step S15, the device maintenance device 10 displays the execution button of the maintenance item specified in the process of step S14 on the touch panel 15 together with the parameters of the field device 19 displayed in the process of step S14 ( Step S16).
By displaying the execution button of the specified maintenance item together with the parameters of the field device 19, the maintenance item for the displayed field device 19 can be executed with one touch.

After executing the process of step S16, the device maintenance device 10 determines whether or not to reacquire the information of the field device 19 executed in the process of step S12 (step S17). For example, when the worker reconnects the device maintenance device 1 to the field device 19 having a different device address, it is necessary to reacquire the information of the field device 19. The equipment maintenance device 10 may determine the necessity of reacquisition by the presence or absence of an explicit instruction from the operator or by automatically detecting a change in the connection status of the communication I / F 16. If it is determined to execute the reacquisition (step S17: YES), the equipment maintenance device 10 returns to the process of step S11 and reacquires the information of the field equipment 19.

On the other hand, when it is determined that the reacquisition is not executed (step S17: NO), the equipment maintenance device 10 determines whether or not to edit the maintenance item. Depending on the maintenance item, various setting items for executing the maintenance item are required. By editing the maintenance item, it is possible to reset the setting item for executing the maintenance item. The equipment maintenance device 10 may determine whether or not to edit the maintenance item depending on whether or not there is an explicit instruction from the operator or whether or not the maintenance item has no setting item.

When it is determined that the maintenance item is to be edited, the equipment maintenance device 10 provides a UI for editing the maintenance item via the touch panel 15 (step S22). After executing the process of step S22, the equipment maintenance device 10 displays the maintenance item again in the process of step S16.

On the other hand, when it is determined that the maintenance item is not edited, the equipment maintenance device 10 determines whether or not the execution button of the maintenance item has been pressed (operated) by the operator (step S23). Whether or not the maintenance item execution button is pressed by the operator can be determined, for example, by the maintenance execution unit 106 monitoring the operation event of the touch panel 15.

When it is determined that the execution button has been operated by the operator (step S23: YES), the equipment maintenance device 10 executes the maintenance item corresponding to the pressed execution button (step S24). The maintenance item may be executed immediately after the execution button is pressed, or may be executed after another display or operation is performed after the execution button is pressed. For example, the maintenance item may be executed by pressing the start button 1131 of FIG. 6 after the display of the touch panel 15 transitions to the display of FIG. 6 described later after the execution button is pressed. In addition, even if the maintenance item is executed after the execution button is pressed, a display confirming whether or not to execute the execution, or an editable display of the contents related to the execution is performed and an operation for these displays is performed. Good.

Execution of the maintenance item can be carried out by the maintenance execution unit 106. After executing the process of step S24, the equipment maintenance device 10 saves the result of the executed maintenance item (step S25). The storage of the results of the executed maintenance items can be carried out by the maintenance information storage unit 107. After executing the process of step S25, the equipment maintenance device 10 returns to the process of step S14 and re-executes the identification of the maintenance item. That is, the identification of the maintenance item in the process of step S14 is executed again according to the result of the executed maintenance item. By executing the identification of the maintenance item again, for example, on the touch panel 15, the display of the execution button of the executed maintenance item can be deleted, the display order of the execution button of the executed maintenance item can be changed, or the like. It is possible to display the execution button of the maintenance item of.

On the other hand, when it is determined that the execution button is not operated by the operator (step S23: NO), the equipment maintenance device 10 determines whether or not to end the processing of the flowchart shown in FIG. 3 (step S26). Whether or not to end the process is determined, for example, whether or not the display screen of the touch panel 15 has switched from a display screen capable of executing maintenance items to another display screen, and whether or not the power switch has been turned off.
