Description

The present invention relates to a device management apparatus that grasps the state of valves as field devices used in plants and the like.

Various valves are used in plants such as control valves and gas governors. In addition, an emergency shutoff valve that shuts off in order to ensure safety when an abnormality occurs is also used in the plant. This emergency shutoff valve is normally held in a fully opened state. For this reason, even if the emergency cutoff valve is stuck and does not operate in an emergency, it is difficult to detect the sticking of the emergency cutoff valve.

In order to detect the above-mentioned valve failure, a valve full-close test is regularly performed. This fully closed test causes the cost to rise because the plant is shut down and executed. On the other hand, in the Partial Stroke Test (PST), the valve is not fully closed and is operated a little while the plant is in operation to confirm the initial operation. With PST, the interval between full-closed tests can be extended, and maintenance and maintenance costs can be reduced (see Patent Document 1, Patent Document 2, and Non-Patent Document 1).

The confirmation unit 104 performs the above-described confirmation at the time when the acquisition unit 102 performs the acquisition operation at the set cycle. The acquisition unit 102 acquires the valve information specified by the valve identification information confirmed by the confirmation unit 104.

The display control unit 105 causes the display unit 106 to display the valve information stored in the test result storage unit 103 for each valve identification information. Not acquired the display control unit 108, non-acquisition unit 102 confirmation unit 104 to confirm for notifying that there is not acquired in the region displayed valve information of the valve identification information has not been acquired valve information The acquisition display is displayed on the display unit 106.

Next, an operation example of the device management apparatus according to the embodiment of the present invention will be described with reference to the flowchart of FIG.

First, in step S201, the display control unit 105 causes the display unit 106 to display the valve information including the result of the partial stroke test stored in the test result storage unit 103 for each valve identification information.

Next, in step S202, the acquisition unit 102 confirms that the valve information acquisition date and time has come. When it is the date and time of valve information acquisition (y in step S202), the confirmation unit 104 controls the opening degree of the valve specified by the valve identification information stored in the identification information storage unit 101 in step S203. Check the valve identification information that the test execution date and time included in the result of the partial stroke test stored in the positioner is after the date and time when the acquisition was performed immediately before. Note that the set time (time axis) in the positioner and the set time (time axis) in the device management apparatus may be different. In consideration of such a case, the judgment before and after the test execution date and time may be allowed if the error is several seconds.

When the confirmation unit 104 confirms the valve identification information whose test date and time is after the date and time when the acquisition was performed immediately before (y in step S203), first, in step S204, the unacquired display control unit 108 confirms. The display unit 106 displays an unacquired display for notifying that there is unacquired information in the area where the valve information of the valve identification information for which the acquisition unit 102 has confirmed and the valve information has not been acquired by the acquisition unit 102. ..

Here, the display unit 107 displays a list of information acquired immediately before the valve information of the valve specified by the valve identification information stored in the identification information storage unit 101. For example, the valve identification information is displayed in the "Device tag" item, the alert occurrence status is displayed in the "Alert" item, the test execution date and time is displayed in the "PST execution date and time" item, and the "Next PST schedule date and time" item is displayed. The date and time information of the scheduled execution of the partial stroke test is displayed in the item. In addition, “unacquired” indicating that the valve information has not been acquired is displayed in the “result data” item of the valve identification information that is after the date and time when the immediately preceding acquisition was performed.

Next, in step S205, the acquisition unit 102 acquires the valve information specified by the valve identification information confirmed by the confirmation unit 104. Acquisition unit 102, the valve identification information of the valve the valve information including the results of the partial stroke test stored in the positioner for controlling the opening of a valve specified by the valve identification information stored in the identification information storage unit 101 It is also acquired via the network 121. Next, in step S206, the valve information acquired by the acquisition unit 102 is stored in the test result storage unit 103 together with the valve identification information.

Next, in step S207, the display control unit 105 updates the display of the display unit 106 with new valve information including the result of the partial stroke test stored in the test result storage unit 103. When the valve information operation described above is performed for all the targets (y in step S208), the acquisition unit 102 waits until the next valve information acquisition date and time (step S202). The above operation is continued until the end is instructed (step S209).

The device management device described above is a computer device including a CPU (Central Processing Unit), a main storage device, an external storage device, a network connection device, and the like, and a program expanded in the main storage device. By the CPU operating, the above-described functions are realized. Further, each function may be distributed to a plurality of computer devices.

As described above, according to the present invention, the acquisition unit is configured to acquire the valve information at the set cycle, so that the results of all target partial stroke tests are the device management apparatus. You will be able to check easily in. In addition, since the administrator or operator does not need to obtain the valve information each time, the work load is reduced.

For example, it becomes easier to understand how the PST is executed in the device in the valve of the entire system. In addition, it is possible to grasp at a glance what the state of the emergency shutoff valve that operates in an emergency of the plant is, and to give a sense of security to the manager and the operator. In addition, it becomes easy for the administrator and the operator to grasp the execution schedule of the PST by the schedule function and the result of the execution. The date and time at which the PST is scheduled to be executed for a plurality of valves can be known at a glance, and the timing of the next PST execution can be adjusted among the valves.

It should be noted that if there is alert information included in the valve information stored in the test result storage unit, and if the valve information has alert information, an alert is displayed in the area where the valve information of the valve identification information is displayed. You may make it display the alert display which shows that it has generate|occur|produced. Also, the content of the alert that has occurred may be displayed. Further, the stored valve information such as the partial stroke test result may be displayed by a trend graph or the like.

Further, in the device management apparatus, an instruction for canceling the alert may be notified to the valve (positioner) in which the alert is generated. In addition, this alert cancellation instruction notification may be performed for a plurality of valves. Further, the pattern creation of the partial stroke test and the partial stroke test of the created pattern may be performed from the device management apparatus side. Further, the parameter of the partial stroke test executed in the valve (positioner) may be set from the device management apparatus.

Also, based on the date and time information of the scheduled partial stroke test execution in the valve information stored in the test result storage unit, immediately before the partial stroke test is executed, the equipment management device notifies the administrator or operator of the partial stroke test. You may be able to. For example, it may be notified by a mail system. Further, when the test is performed, the valve information of the valve may be notified in the same manner.

Further, for example, the display value such as the implementation schedule displayed on the display unit may be selected by the operation of the administrator, and the setting of the selected item may be changed. For example, if the displayed scheduled dates of implementation overlap, the scheduled dates of implementation can be changed so that this overlap can be resolved. The settings such as the scheduled execution date changed in this way are reflected in the target positioner (field device) by the setting reflection unit included in the device management apparatus. The setting reflecting unit reflects the valve information whose setting has been changed on the positioner of the valve specified by the associated valve identification information.
