Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Field of Industrial Application) The present invention relates to an operation prohibition information providing device that displays devices whose operation is prohibited due to permitted work.

(Prior art) In recent years, CR has been used as equipment for operating industrial plants.
CRT touch operation devices that use a T display device for both monitoring and operation are becoming widely used1.For example, CRT touch operation devices are also used in operation monitoring equipment at nuclear power plants. things are used.

On the other hand, at nuclear power plants, work such as inspection and equipment replacement of plant equipment is permitted. It is forbidden. below,
This device whose operation is prohibited is called a TAG.

When such a PTW is performed, as shown in FIG.
As shown in FIG. 13, an operation prohibition hole LB in which the TAG number representing G, the name of the person in charge of the work, the registration date of the PTW, etc. is written is hung on the operation switch ST of each TAG.

Furthermore, when a plurality of PTWs are executed in parallel, the operation switch of one TAG may be provided with an operation prohibiting hole for the plurality of PTWs.

Then, when one PTII ends, that PTIll
The operation-inhibiting hole is removed from the operation switch.

In this way, when one or more operation prohibition holes are hung, operation of the operation switch is prohibited,
This ensures safety during work.

In this way, when performing PTlil, TAG operation is prohibited, so in a device that monitors operation by CRT touch operation, it is necessary to clearly display devices whose operation is prohibited.

A conventional example of such a CRT touch operation operation monitoring device is shown in FIG. In addition, in the same figure, only the part that identifies and displays the TAG is shown.

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

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

The input device 6 is used to input the identification information of the TAG associated with the PTV when the PTW is executed.

The input data is sent to TAG via TAG data input means 7.
It is added to the AG information processing means 8.

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

The plant status display means 4 receives T from the TAG information processing means.
When the AG is notified, an operation prohibition mark indicating that the operation is prohibited is displayed near the display of the TAG.

For example, as shown in FIG. 15(a), while the monitoring screen of the plant 1 is being displayed, the TAG information processing means 8 uses the input device 6 to input the equipment number of Fool to the plant status display means 4 as TAG. Notice.

As a result, as shown in FIG. 4B, an operation prohibition mark MK is displayed near the display symbol of the FOOI device. Note that this equipment number is assigned in advance to all plant equipment.

Also, when PTW ends and TAG is canceled,
If you input that information from the input device 6, the TAG will be canceled.
The AG information processing means 8 is notified, and the TAG information processing means 8 thereby stops outputting the TAG information.

As a result, the plant status display means 4 stops displaying the operation prohibition mark.

However, such a device has the following disadvantages.

As mentioned above, for one device, multiple PTit
However, in the above-mentioned device,
TAG processing regarding multiple PTWs cannot be performed.

Therefore, conventionally, TAGs have been managed in the following manner.

That is, a board is formed by nailing one nail to one operating switch of one device. On each nail,
Give it the same name as the operation switch. When performing PTIil, an operation prohibition hole similar to that shown in FIG. 12 is hung on the nail of the board, and the device number of the TAG is inputted from the input bag W6.

As a result, as described above, the operation prohibition mark MK is displayed on the CRT display M5, and the operator performs the driving operation while referring to the display.

When the PTW is completed, the operation-inhibiting hole on the PTV is removed from the nail on the board. Then, for a nail from which all operation-prohibiting holes have been removed, an operation to cancel the corresponding TAG is performed using the input bag M6.

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

In this way, TAGs related to multiple PTWs are managed.

(Problems to be Solved by the Invention) However, such conventional methods have the following disadvantages.

(a) Multiple operation-prohibited holes for one device cannot be managed all at once.

(b) The operator must operate the operation-prohibited hole and the input device, which is complicated and burdensome, and is also prone to operational errors.

(1) The device whose operation is prohibited (TAG) can be recognized, but the relationship with the PTW cannot be easily known.

For example, it takes time to check how many PTWs are set for an arbitrary TAG, or whether a specific AG is a target for an arbitrary PTW.

(1) It is necessary for the operator to operate the operation prohibition hole and the input device, and the operation is complicated and burdensome, and operation errors are likely to occur.

The present invention has been made in view of such circumstances, and
It is an object of the present invention to provide an operation prohibition information providing device that can easily manage Tv and TAG.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a data input means for inputting permission work for a plant, data on equipment whose operation is prohibited due to the permission work, and output requests for various information. Then, an information table summarizing the permitted work and operation prohibited equipment data input through this data input means is created, and if there is one or more permitted work whose operation is prohibited, an operation prohibited display is displayed for that equipment. At the same time, when an output request is inputted from the data input means, a data processing means forms information for displaying a list of the items requested at that time, and a data processing means that generates information for displaying a list of items requested at that time; a plant status display means for displaying the state of the equipment and displaying a mark indicating that the operation of the equipment is prohibited when the data processing means commands the equipment to be prohibited from operating; and a list displaying information from the data processing means. It is equipped with an output means that outputs the contents when the is output.

(Function) Therefore, the relationship between PTW and TAG is handled centrally, and for equipment designated as TAG by one or more PTVs, an operation prohibition mark is automatically displayed, which prevents operators from working. significantly reduced. Also, P.T.
Since you can display a list of Ii and TAG,

Here, the TAG information table is a set of TAG number information indicating the device number and a display flag indicating display of an operation prohibition mark for each device.

When the PTW related information output processing means 25 receives an output request from the output request inputting means 14, it forms display information that displays a list of the contents of the PTW related information table formed by the PTW related information processing means 22.

The display information is output to the PTW related information output means 15.

When an output request is input from the output request input means 14, the TAG-related information output processing means 26 forms display information that lists the contents of the TAG-related information table formed by the TAG-related information processing means 23. The display information is output to the TAG related information output means 16.

The PTW related information output means 15 forms recording information to be output to the printer 27 based on the display information input from the PTW related information output processing means 25, and the TAG related information output means 16 forms record information to be output to the printer 27. The recording information to be output to the printer 27 is formed based on the display information input from the printer 27.

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

With the above configuration, when the operator operates the interactive input device 20 to input information regarding the operation of the PTII/TAG,
First, as shown in FIG. 4, TAG data and PTt
il data is input (process 101).

In this process 101, the interactive display device 20 displays an interactive screen as shown in FIG. You can enter your name, registration date, and TAG number. In this case, the PTW number is ``r150'', the processing type is ``l'', and the person in charge is rs.
AITOHJ has r890220J as the registration date and T
rK12-F002J, rK12-CO as AG number
It is assumed that O3J and rK15-FO05J are each 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), PT
r150J is the W number information and r is the person in charge name information.
sAITOHJ is r890220J as registration date information
but.

rK12-F002J, "Ni12" as TAG number information
-COO3J and rK15-FOO5J are set respectively.

Then, the contents of the input data table formed at that time are added to the PTW related information table (process 103
). For example, as shown in FIG. 6(b), when the above operation is performed with the PTW number information "90", r122J, and r123J already registered,
An item with T11 number information r150J 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, as shown in FIG. 6(C), in this case, r
K12-F002J, rK12-C003J, rK15
-FOO5", PTW number information r150J is added to each of the three TAG number information items.

Then, the contents of the PTW count value information in the TAG related information table are updated (process 105). In this case, P.T.
The values of the P-W count value information of the TAG number information items to which the V number information r150J has been added are each increased by one.

Next, for each TAG number information item in the TAG related information table, the content of PTII count value information is checked (determination 106), and if the content is O, the TAG information table (Fig. 6 ( Process 107) to set "O" to the display flag of the corresponding TAG number information (see d)), and if the content is 1 or more, set the display flag of the corresponding TAG number information of the TAG information table to "O". Set to "1" (process 108).

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

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

As a result, a mark indicating that the operation is prohibited is displayed on the CR7 display device 5 near the display symbol of the device set in the TAG at that time.

On the other hand, if you operate the interactive input bag N20 and specify "2" rPTW related information output request as the function, as shown in FIG.
"Specify number" and "2. All TAG numbers" are displayed.

Therefore, if you enter "1" as the processing type, the first TAG number to be displayed (start TAG number) and the last TAG number will be displayed.
You will be asked to enter a number (ending TAG number), so enter rK12-FOOIJ as the starting TAG number, and enter rK12-FOOIJ as the ending TAG number.
When rK15-FOO5J is input as the number, the input data is output to the PTV related information output processing means 25 via the output request input means 14.

As a result, the PTV-related information output processing means 25 takes out the contents of the PTv-related information table formed by the PTW-related information processing means 22 at that time, forms display information for displaying it, and displays the display information. is output to the PTW related information output means 15.

As a result, the printer 27 records and outputs a report that can display a list of the contents of the 17w related information table, as shown in FIG.

Similarly, the interactive input device 20 allows TAG
When a related information output request is issued, 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 extracts the contents of the TAG-related information table formed by the TAG-related information processing means 23 at that time, creates a display method for displaying the contents, and displays the display information. The information is output to the TAG related information output means 16.

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

In addition, by operating the interactive input device 20, you can select r as a function.
