Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) [0001] The present invention relates to an operation prohibition information providing apparatus for displaying a device for which operation is prohibited due to permitting work.

(Prior Art) In recent years, CR has been used as a device for operating and operating an industrial plant.
The one that uses the CRT touch operation that uses the T display device for both monitoring and operation has been widely used. For example, the operation monitoring device for a nuclear power plant also uses this CRT touch operation. Things are being used.

On the other hand, at a nuclear power plant, operations such as inspection and equipment replacement regarding plant equipment are permitted, and operation of the equipment subject to the work is prohibited during the permitted work (hereinafter referred to as PTW (permit work)). To be done. Hereinafter, this operation prohibited device is referred to as a TAG.

When such a PTW is carried out, as shown in Fig. 12, the operation prohibition in which the PTW number for identifying the PTW, the TAG number representing the TAG, the name of the worker in charge, the registration date of the PTW, etc. are entered is prohibited. As shown in FIG. 13, the tag LB is hung on the operation switch ST of each TAG.

In addition, when a plurality of PTWs are executed in parallel, an operation prohibition tag for a plurality of PTWs may be placed on one TAG operation switch.

Then, when one PTW ends, the operation prohibition tag associated with the PTW is removed from the operation switch.

In this way, when one or more operation prohibition tags are hung, it is prohibited to operate the operation switch, so that safety during work can be secured.

As described above, since the operation of the TAG is prohibited when performing the PTW, the device for which operation is monitored by the CRT touch operation needs to clearly display the device whose operation is prohibited.

FIG. 14 shows a conventional example of the operation monitoring device for such a CRT touch operation. In the figure, only the portion for identifying and displaying the TAG is shown.

The process signal from the plant 1 is sampled by the process input device 2 and input to the plant state display means 4 of the operation monitoring device 3.

The plant status display means 4 displays the status of each device of the plant 1 by a simplified diagram of the system diagram of the plant 1 and the display information is displayed on the CRT display device 5 for performing the CRT touch operation. It is being output.

The input device 6 inputs the identification information of the TAG relating to the PTW when the PTW is executed, and the input data is the TAG information processing means 8 via the TAG data input means 7.
Is added to

The TAG information processing means 8 outputs the inputted TAG identification information to the plant status display means 4.

The plant status display means 4 displays the TAG information from the TAG information processing means.
Is notified, an operation prohibition mark indicating operation prohibition is displayed near the TAG display.

For example, as shown in FIG. 15 (a), when the monitoring screen of the plant 1 is displayed, the TAG information processing unit 8 from the input device 6 uses the device number of F001 as the TAG on the plant state display unit 4. Notice.

As a result, as shown in FIG. 9B, the operation prohibition mark MK is displayed near the display symbol of the device of F001. Note that this equipment number is assigned to all plant equipment in advance.

Further, when the TAG is canceled after the PTW ends, if the fact is input from the input device 6, the cancellation of the TAG is notified to the TAG information processing means 8, whereby the TAG information processing means 8 is notified.
Cancels the output of TAG information.

As a result, the plant status display means 4 cancels the display of the operation prohibition mark MK.

However, such a device has the following disadvantages.

As described above, one device is designated as a TAG by a plurality of PTWs, but the above-described device cannot perform TAG processing regarding a plurality of PTWs.

Therefore, conventionally, the TAG is managed as follows.

That is, a board with one nail is formed on the operation switch of one device. Each nail has the same name as the operation switch. When performing PTW, the operation prohibition tag similar to that shown in FIG. 12 is hung on the nail of the board, and the TAG device number is input from the input device 6.

As a result, the operation prohibition mark MK is displayed on the CRT display device 5 as described above, and the operator refers to the display to perform the driving operation.

When the PTW ends, remove the operation prohibition tag for the PTW from the board nail. Then, for the nail from which all the operation prohibition tags have been removed, the operation of canceling the corresponding TAG is performed from the input device 6.

As a result, as described above, the device is excluded from the target of TAG, and the display of the operation prohibition mark MK disappears.

In this way, TAG management relating to a plurality of PTWs is performed.

(Problems to be solved by the invention) However, such a conventional method has the following disadvantages.

(A) It is not possible to collectively manage multiple operation prohibition tags for one device.

(B) The operator must operate the operation prohibition tag and the input device, and the operation is complicated and burdensome, and operation mistakes are likely to occur.

(C) I can recognize the device (TAG) whose operation is prohibited, but I cannot easily know the relation with PTW. For example, it takes time to find out how many PTWs are set for an arbitrary TAG or which TAG is targeted for an arbitrary PTW.

(D) It is necessary for the operator to operate the operation prohibition tag and the input device, and the operation is complicated and burdensome, and operation mistakes are likely to occur.

The present invention has been made in view of such circumstances,
It is intended to provide an operation prohibition information providing device capable of easily managing PTW and TAG.

The recording information to be output to the printer 27 is formed based on the display information input from the related information output processing means 26.

Here, the printer 27 corresponds to the output device 17 in FIG.

With the above configuration, the operator operates the interactive input device 20.
When inputting information relating to PTW / TAG operation, first, as shown in FIG. 4, TAG data and PTW data are input (process 101).

In this process 101, an interactive screen as shown in FIG. 5 is displayed on the interactive display device 20. In this state, if the user selects and inputs the function item “1”, the PWT number, the process type, the person in charge You can enter your name, registration date, and TAG number.
In this case, the PTW number is "150", the process type is "1", the data entry is "SATOH", and the person in charge is "SATOH".
"890220" as the registration date and "K12-F00" as the TAG number
It is assumed that three items, "2", "K13-C003", and "K15-F005", have been input.

Next, an input data table is created based on the input data input from the interactive input device 20 (process 10).
2). In this case, as shown in FIG. 6 (a), "150" is set as the PTW number information and "SAITO
"H" is the registration date information "890220" and the TAG number information is "K12-F002", "K13C003", "K15-F005".
Two are set respectively.

Then, the contents of the input data table formed at that time are added to the PTW-related information table (process 10).
3). For example, as shown in FIG. 6 (b), three pieces of PTW number information “90”, “122”, and “123” are already registered information, and when the above operation is performed, the PTW number information "150" is added.

Next, the contents of the input data table at that time are added to the TAG related information table (process 104). For example,
In this case, as shown in FIG. 6 (c), "K12-F00
PTW number information “150” is added to each of the three items of TAG number information “2”, “K13-C003”, and “K15-F005”.

Then, the content of the PTW count value information in the TAG related information table is updated (process 105). In this case, the value of the PTW count value information of the item of the TAG number information to which the PTW number information “150” is added is incremented by one.

Next, for each TAG number information item in the TAG related information table, the content of the PTW count value information is checked (decision 106), and if the content is 0, the TAG information table (see FIG. "0" is set to the display flag of the corresponding TAG number information (see d)) (process 107), and
When the content is 1 or more, the display flag of the corresponding TAG number information in the TAG information table is set to "1" (process 108).

In this way, the contents of the PTW related information table, the TAG related information table, and the TAG information table are appropriately updated based on the data input from the interactive input device 20.

Then, the TAG information processing means 24 outputs the TAG number information of each item of the TAG information table whose display flag is set to "1" to the plant state display means 4 as the operation prohibited operation equipment number. .

As a result, on the CRT display device 5, a mark indicating operation prohibition is displayed near the display symbol of the device set to TAG at that time.

On the other hand, when the interactive input device 20 is operated and, for example, as shown in FIG. 7, "PTW-related information output request" of "2" is designated as the function, "1. TAG number designation" is designated as the processing type. And "2. All TAG numbers" are displayed.

Therefore, if you enter "1" as the process type, you will be prompted to enter the first TAG number (start TAG number) to display and the end TAG number (end TAG number). Therefore, enter "K12-F001" as the start TAG number. ”As the end TAG number
When "5" is input, the input data is output to the PTW related information output processing means 25 via the output request input means 14.

As a result, the PTW-related information output processing means 25 extracts the contents of the PTW-related information table formed by the PTW-related information processing means 22 at that time, forms display information for listing the contents, and outputs the display information to the PTW-related information. Output to the related information output means 15.

As a result, as shown in FIG. 8, the printer 27 records and outputs a report capable of displaying a list of the contents of the PTW-related information table.

Similarly, when the interactive input device 20 commands a TAG related information output request, the command is output from the output request input means 14 to the TAG related information output processing means 26.

As a result, the TAG related information output processing means 26 takes out the contents of the TAG related information table formed by the TAG related information processing means 23 at that time, forms a display method for displaying the list, and displays the display information by TAG. Output to the related information output means 16.

As a result, from the printer 27, as shown in FIG.
A report that lists the contents of the TAG-related information table is recorded and output.

Also, by operating the interactive input device 20, as a function "1.

The G information table is appropriately modified, and the operation prohibition mark is added to the display content of the CRT display device 5 for the device designated as the TAG, so that the operator can easily confirm the operation prohibited device. be able to.

Also, when the PTW ends and the registered contents related to that PTW are deleted, the PTW related information table, TAG
The related information table and the TAG information table are appropriately modified, and the display content of the CRT display device 5 is also modified.

Therefore, the operator does not need to specially manage the relationship between the PTW and the TAG, and the burden of the driving operation is significantly reduced. Moreover, operation mistakes are reduced.

By the way, in the above-mentioned embodiment, only the printer is used as the output device, but it is also possible to use both the printer and the CRT display device. In that case,
As shown in FIG. 10, it is advisable to newly provide an operation item for selecting an output device.

Further, in the above-described embodiment, when one PTW is completed, all the data related to the PTW is deleted, but in the case where the number of devices specified as TAG decreases as the PTW progresses. For example, as shown in FIG. 11, it is preferable to be able to select a device from which the designation of TAG is excluded from the registered contents.

Furthermore, it is also possible to set whether or not to display the operation prohibition for each TAG. By doing this, when the same PTW is executed after the PTW is completed once, the operation prohibition display is set not to be displayed when the PTW is completed, and the operation prohibition display is displayed when the PTW is executed again. By doing so, it is possible to save the trouble of repeating the same data input operation.

Further, in the above-described embodiment, the interactive input device in which the CRT display device and the keyboard input device are combined is used as the input device, but the input device may have a configuration other than that.

As described above, according to the present invention, the PTW and the TAG are
Since the information is collectively managed and the operation prohibition display is performed, it is possible to significantly reduce the time and effort of the operator's operation, and it is possible to significantly reduce the operation mistakes. Also, since the information related to PTW and TAG is displayed in a list, for example, for any TAG, PTW
There is also an effect that it is possible to easily check how many TAGs are set or which TAG is targeted for an arbitrary PTW.
