Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation device for storing an operation of a plant by an operator as a history and outputting the operation history data to an output device such as a display device.

[0002]

2. Description of the Related Art In general, the operation of an industrial plant is performed by monitoring the plant condition at the site where plant auxiliary equipment is installed, and then performing centralized monitoring operation from a remote location such as a central operating room. The system is shifting to the monitoring operation method. As a result, the load on the operators is reduced, the number of operators is reduced, or the plant operation is accelerated.

For such centralized monitoring operation, at the site where the plant equipment is arranged, a sensor for measuring the amount of plant state, switches for detecting the state of auxiliary equipment such as valve opening / closing, and auxiliary equipment. A drive device for remote control of is installed. On the other hand, in the central operation room, there are indicators such as meters for displaying the plant state quantity measured by sensors, lamps for indicating the state of auxiliary equipment, and operating equipment such as switches for starting and stopping auxiliary equipment. An operation panel is provided, and a method is adopted in which operation is performed while monitoring plant state quantities such as temperature and pressure and the state of auxiliary equipment.

In such an operating method, the number of indicators and operating devices increases as the target plant grows in size and complexity, resulting in an increase in the size of the monitoring operation panel and an increase in the operator's burden, which is economical and economical. There is a problem in terms of operability. Therefore, as one of the solutions to such problems, a monitor control system in which a computer is applied to plant operation has come to be used.

As a man-machine interface of this supervisory control system, a display device for displaying a screen such as a CRT display device, a plasma display device, a liquid crystal display device or the like is used. With the development of various input devices, their operability has reached a level equal to or higher than that of a monitoring operation panel.

Thus, in recent years, a combination of a display device and a keyboard input device arranged on the desk of the display device has been used in place of the monitor operation panel. Hereinafter, this is called an operation device. A device using a CRT display device as a display device is particularly called a CRT operation device. Hereinafter, a CRT operation device will be described as an example of the operation device.

In the plant operation operation by the CRT operation device, normally, when the operation of the operator is performed, the operation of the operator is only confirmed on the spot by the CRT display device. A CRT operation operation that can be confirmed later is also being developed. This is to save the plant operation operation from the CRT operation device as a history and to output the operation history of the plant operation operation to an output device such as a CRT display device at the request of an operator after the CRT operation operation. .

Further, by selecting any operation data (operation end) on the screen of the CRT display device while the operation history is displayed as a list on the CRT display device, the operation frame of the operation end is included. Some have a function for promptly operating the operation end from displaying operation history data, such as displaying on a screen.

FIG. 22 is a block diagram of such a conventional CRT operation device 1. The touch input means 11, which is an input means, instructs the input / output processing means 14 to select an operating end of the plant to be operated and what operation to perform on the operating end.
For example, when a start command is issued to the rotary auxiliary device, an instruction for issuing the start command is given to the plant control device, which is the operating end of the rotary auxiliary device. In addition, the CRT display device 12
Displays the operating status of the plant and the contents of the dialogue with the operator. The operating status of the plant is displayed together with the system diagram, and the man-machine screen such as the menu screen for the above-mentioned operation operation is displayed. Further, the keyboard input device 13 which is an input means, for example, when outputting operation history data, displays necessary characters such as operation end number and date and time in the input area on the screen of the CRT operation machine displayed on the display device 12. Enter the key.

Next, the input information from the touch input means 11 and the keyboard input device 13 is input to the input / output processing means 14 and processed, and the CRT operation processing means 15 is then processed.
The input information is transmitted to the operation history dialogue processing means 17.

When the input information from the touch input means 11 or the keyboard input device 13 is input through the input / output processing means 14, the CRT operation processing means 15 refers to the operating end information table 23 to input the input information. The operation information for the operation end designated by is replaced with the operation output signal and output to the plant control device 25 via the data transmission means 16. The operated operation end and the operation content are output to the operation history storage processing unit 18.

As shown in FIG. 23, the operating end information table 23 is for outputting an operating end number, an operating end name, an input end for displaying an operating end state, an opening / closing operation, etc. of an operating end targeted for CRT operation. Is a data table in which the operation item number C of the output point is stored, and the CRT operation processing means 15 has the operation end information table 23.
With reference to, the operation output signal is output to the corresponding operation end. For example, when the operation end number is CV-101 and the operation item number is "2", the command to close the condenser outlet valve is output, and the output point is It will be C002.

The operation history storage means 18 writes the operation end number and the operation content in the operation history data file 19 when the operation end operated by the CRT operation processing means 15 and the operation content are input. As shown in FIG. 24, the operation history data file 19 includes the date and time when the CRT operation processing means 15 operates the operation end,
The operated operation number and the operation item are stored as operation history data. The operation contents operated by the CRT operation processing means 15 are represented by operation item numbers. In this way, the operation history data processed by the CRT operation processing means 15 is accumulated in the operation history data file 19.

Next, in outputting the operation history of the plant operation operation, the operation history dialogue processing means 17 displays the operation history dialogue screen as shown in FIG. 25 on the CRT display device 12 in response to a command from the operator. To do. Then, the operation history request range and the execution request input by the operator are processed.
As shown in FIG. 25, the operation history request range specifies operation history data on a daily basis.

The operation history output control means 20 issues an edit request to the operation history editing means 21 at the timing when the operation history interactive request means and the operation history search request are input from the operation history interactive processing means 17, and edit range information is added to the operation history editing means. Hand it to 21. Further, upon receipt of the edit completion notification from the operation history editing means 21, a dialogue screen display end request is issued to the operation history dialogue processing means 17, and a history data output request is issued to the operation history output processing means 24.

The operation history editing means 21 reads history data from the start point to the end point of the operation history data file 19 on the basis of the editing range information input from the operation history output control means 20, and sets the operation end information table 23. Referring to the operation end number and the operation item number, the operation end name and the operation item name are extracted and written in the operation history output data file 22 in the format shown in FIG. When the writing to the operation history output data file 22 is completed, an edit completion notification is issued to the operation history output control means 20.

The operation history output processing means 24 receives the output request from the operation history output control type means 20, reads the contents of the operation history output data file 22, and inputs / outputs processing means 1
A list is displayed on the CRT display device 12 via 4. As a result, when the operation history data of the plant operation operation is output to the CRT display device 12, the history is stored in the operation history output data file 22.

Here, as a conventional CRT operation device, there is also a device provided with a free group function that allows the operation end for performing the CRT operation operation to be allocated online through a dialogue. FIG. 27 shows the configuration of a CRT operation device having the free group function.

The free group function will be described below. The free group function is to assign the operation end where the operation operation is performed to the group in advance,
As shown in FIG. 27, with respect to the components shown in FIG.
A free group dialogue processing means 26, a free group editing processing means 27, and a free group operation end allocation data file 28 are additionally provided.

That is, the free group dialogue processing means 2
Reference numeral 6 carries out an interactive processing for allocating the operating end when a free group function activation request is issued from the input / output processing means, and the free group edit processing means 27 inputs / outputs the operating end assigned by the free group interactive processing means 26. The point information is set in the free group operation end allocation data file 28. When performing an operation operation, the free group interaction processing means 26 displays a free group display screen, which is an operation screen of a plurality of allocated operation ends, on the CRT display device 12, and the operation editing processing means 27 causes the free group display processing means 27 to perform a free group operation. An operation command signal to the operation end of the plant is output based on the operation operation content input via the display screen.

The free group function is composed of two types of screens, a free group assignment screen shown in FIG. 28 and a free group display screen shown in FIG. FIG.
In the free group allocation screen of, each operation frame has an operation end number peculiar to the operation end. The operation end number is keyed in the parentheses 1 to 8 and the allocation execution PB in the screen is touched. As a result, an arbitrary operation frame can be assigned to each of the locations 1 to 8.

In the free group display screen of FIG. 29, the operation frame set on the free group allocation screen is displayed on the free group display screen, and the actual CRT operation operation is performed on this free group display screen. Be seen. In the current general CRT operation device, as shown in FIG.
A strip-shaped window called an operation window is displayed on the screen, and all actual CRT operation operations are performed by dialogues in this operation window. As for the width of the operation window, as shown in the example of the free group display screen of FIG. 29, a maximum of eight operation windows can be displayed. With the free group function, up to eight can be set on one screen.

In response to the free group function activation request from the input / output processing means 14, the free group dialogue processing means 26 displays the free group assignment screen shown in FIG. 29 to perform the dialogue processing of operating end assignment. The free group edit processing means 27 receives the operation end allocation request from the free group interaction processing means 26, retrieves the requested operation end number from the operation end information table 23, and frees the input / output point information of the operation end. The data is set in the group operation end allocation data file 28. The processing up to this point is the processing for allocating the operation frame to the free group.

Next, the CRT operation operation is actually performed using the free group thus allocated. The processing in that case will be described below. First, the input / output processing means 14 sends a display request for the free group display screen shown in FIG. 29 to the free group interaction processing means 26, whereby the free group interaction processing means 26 sends CR to the CRT operation processing means 15.
Request that T operation be performed from the free group display screen. In response to the above request, the CRT operation processing means 15 refers to the input / output point information of the currently assigned operating end from the free group operating end assignment data file 28 and performs a normal CRT operation operation.

As described above, as shown in FIGS.
In any of the CRT operation devices shown in FIG. 3, the plant operation record is easily left by storing the CRT operation operation history in the operation history data file 19 and outputting the operation history data to the CRT display device 12. It is possible.

[0026]

However, in such a conventional operation history storage and operation history output method by the CRT operation device, history data arranged in order of operation time is output to the CRT display device as a list. Therefore, in order to display the operation history data desired by the operator, the operator needs to search for the desired operation history data by scrolling the screen of the CRT display device 12.

In some conventional CRT operation devices, the operator specifies the output range of the history data by date and time and displays the history data within the range. Such a system So, for example, if the operator wants to see the historical data related to a certain operating end, or if he / she wants to see the historical data of an operation performed in a special situation (such as a test operation during a plant inspection), an enormous amount of history remains. The operator had to increase the load by searching for the desired data by scrolling.

Further, there is a problem that the information amount of the operation history data is insufficient. In the operation history data in the conventional CRT operation device, there are cases where operation history data that is not related to the original operation of the plant, such as an operation during a test, is collected. In that case, even if the operation history data is referred to, it is impossible to distinguish whether the operation history data is the operation history data of the operation performed in the test or the like or the operation history data of the operation necessary for the original operation of the plant. Therefore, when the operation history data is searched, there is no choice but to search using the operation date as a key, which increases the load on the operator.

There is also the problem of the amount of operation history data collected. In the conventional CRT operation device, the operation history data is stored in the operation history data file 19, but the collection processing is performed when the plant is in a stopped state or when there is no need to collect data such as during a test. Even if there was, all the operation history was collected every time the CRT operation operation was performed. Since a storage medium such as the operation history data file 19 naturally has a maximum number of storages that can be stored, in the conventional CRT operation device, when the operation history data exceeds the maximum number of storages, the oldest data is stored. It was supposed to be erased or overwritten in order each time.

Therefore, in such a conventional method of collecting operation history data in the CRT operation device, in order to collect operation history data which is not actually necessary, it is a record old operation but is very important in operation. There was a danger that the history data would be erased. Therefore, the operator
Before the important operation history data was erased or overwritten due to unnecessary operation history data, it was necessary to read and record the data or save it on another medium such as a floppy disk.

Further, by providing the function of storing and outputting the operation history data, in the conventional CRT operation device, the operation content can be confirmed by a third party other than the operator, but the operation history is the operator. Is not output unless requested by the operator, so that in order for another operator to immediately confirm the operation performed by the operator, attention is paid to the operation content on the CRT display device 12 operated by the operator, or the operation is performed. There was no choice but to confirm the content of the operation by the staff pointing and calling "... the operation has been performed" or by the operation completion voice output by the voice notification device.

In particular, in the operation completion voice output by the voice notification device, since the output target operation end is limited, the CRT operation operation contents cannot always be confirmed.
In addition, even for operators who are located in areas other than the central operating room, such as the computer room, there was no way to confirm whether the operation is currently being performed in the central operating room or what the operation was.

Further, in the conventional free group function, the operator allocates an arbitrary operating end by dialogue, but there is no particular standard of allocation, and the operator allocates it at the discretion of the operator as necessary. . For this reason, when using the free group function for the first time, it was necessary for the operator to search for and allocate the necessary operating end from all operating ends.

Here, considering the operation history data of the CRT operation operation, it can be said that it is the actual result of the CRT operation operation in the previous plant operation. Along with the increase in the scale of the plant, the number of target operation ends operated by the CRT operation device is also increasing. It is important to know at what time, in what procedure, and what operation end does not have to be operated. It can be said to be driving know-how. Therefore, in the conventional CRT operation device that simply allocates the operating end to be operated by the free group function,
It was not possible to accumulate the results of CRT operation operations.

The object of the present invention is to save the operation operation history data in a form that can be searched from various viewpoints, and to extract and output only the history data desired by the operator from the saved data, so that the operator can An object is to obtain an operation device that can reduce the operation load until the desired history data is reached.

When the free group function is provided, the operation history data can be used as the allocation data of the free group to reduce the load on the operator in the allocation of the free group and effectively use the operation know-how. To obtain an operation device that can

Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing the first embodiment of the present invention. The first embodiment differs from the conventional example shown in FIG. 22 in that the operating end number searching means 30 searches the operating history data file 19 for the operating end number requested by the operator, and the operating end searching means 30. A search data address storage memory 31 for storing a pointer address for accessing the operation history data of the searched operation end is added. As a result, the operation history data of the CRT operation operation can be retrieved for each operation end, so that the operation history data of any operation end requested by the operator can be retrieved and output. Other configurations are shown in FIG.
Since they are the same as those shown in, the same elements are given the same reference numerals and the description thereof is omitted.

That is, when the operating end detecting means 30 retrieves the operating history data of the operating end, the operating history editing means 2
Reference numeral 1 edits the operation history data of the operation end searched by the operation end search means 30 as operation history output data and saves it in the operation history output data file 22, and the operation history output processing means 24 outputs the operation history of the operation end. The data is displayed on the CRT display device 12.

Next, the CRT according to the first embodiment
A case where the operation device retrieves the operation history data for each operation end will be described. In FIG. 1, the operation history dialogue processing means 17 displays the dialogue screen of the operation history on the CRT display device 12 as in the conventional example, and processes the execution request inputted by the operator. In this case, as the dialogue screen, the dialogue screen of the operation history as shown in FIG. 2 is displayed, and the operation end number input by the operator through the dialogue screen is passed to the operation history output control means 20.

The operation history output control means 20 issues an edit request to the operation history editing means 21 at the timing of inputting the operation history search request and the requested operation end number from the operation history interactive processing means 17, and selects the operation end to be searched. Operation history section 21
Pass to. Further, upon receipt of the edit completion notification from the operation history editing means 21, a dialogue screen display end request is issued to the operation history dialogue processing means 17, and a history data output request is issued to the operation history output processing means 24.

At this time, when the operation history editing means 21 notifies that there is no search data when the editing is completed, the operation history output display means 24 is not requested to start, and the operation history interactive processing means 17 is notified. Request display that there is no corresponding operation history data.

That is, the operation history editing means 21 passes the search target operation end number input from the operation history output control means 20 to the operation end search means 30, and receives the number of search data as the search end notification. Thereafter, the addresses corresponding to the number of search data items are read from the top of the search data address storage memory 31, and the operation history data existing at the relevant address in the operation history data file 19 is referred to the operation end information table 23 as in the prior art. Write to the operation history output data file 22. Operation history output data file 2
When the writing to 2 is completed, an edit completion notification is issued to the operation history output control means 20, as in the conventional example.

At this time, if the search result of the operating end search means 30 is 0, the operation history editing means 21 does not perform the editing process, and the operation history output control means 20 has completed the editing and the data is 0. Notify that.

FIG. 3 shows a processing flow of the operating end searching means 30. The operation end searching means 30 is the operation history editing means 21.
Enter the operation end number (S1) and the number of search data is 0
Is confirmed (S2), and that the search start address is 0 (S3). Then, the operation history data of the operation end is searched from the operation history data file 19 (S4), and it is determined whether or not there is the corresponding history data (S5). If there is, the corresponding history data. The leading addresses of the above are sequentially written in the search data address storage memory 31 (S6). At that time, the number of search data items is counted (S7), and it is determined whether or not the data search is completed (S7).
8) When the data search is completed, the final search data number is output to the operation history editing means 21 (S9). When the data search is not completed, the address is added by the data size (R-SIZE) of the operation history data and the process returns to step S4 (S10).

Here, the search data address storage memory 3
1 has a data structure as shown in FIG. 4, and stores the address of the history data of the operating end retrieved by the operating end retrieval means 30.

As described above, in the first embodiment, the CRT operation device having the conventional operation history storing and outputting function is further provided with the operation end searching means for searching the operation history data by using the operation end number as a key. Since 30 is provided,
It becomes possible to retrieve and output only the history data regarding an arbitrary operation end. As a result, the operation history data that has been miscellaneously output in the conventional system can be displayed only by limiting the history data requested by the operator.
The load on the operator until the desired history data is reached can be reduced.

Next, FIG. 5 shows a block diagram of the second embodiment of the present invention. This second embodiment is shown in FIG.
As compared with the conventional example shown in FIG. 2, a comment data file 41 storing comment data added to the operation history data.
And a comment registration interactive processing means 40 for registering the comment data in the comment data file 41, and a comment data registered in the comment data file 41 for selecting and adding to the operation history data performed by the CRT operation processing means 15. Comment selection dialogue processing means 42
When there is a request from the operator to output operation history data with comment data as an output request for operation history data from the operator, the operation history editing means 21 operates the operation history data with comment data added. The history output data is edited and saved in the operation history output data file 22, and the operation history output processing means 24 displays the operation history output data of the operation end on the CRT display device 12. Since other configurations are the same as those shown in FIG. 22, the same reference numerals are given to the same elements and the description thereof will be omitted.

That is, the comment registration dialogue processing means 40.
Receives a comment registration screen display request requested by the operator from the input / output processing means 14, displays a comment registration screen for registering comment data to be added to the operation history data for each index, and is set by the operator. The comment data and the comment data index are written and stored in the comment data file 41, which is a storage medium.

On the other hand, the comment selection interactive processing means receives the comment selection screen display request from the operator from the input / output processing means 14 and selects the index of the comment data to be added to the operation history data of the CRT operation operation to be performed. A comment selection screen for displaying the comment data is displayed, and the index of the comment data selected by the operator is written to and saved in the operation history data file 19 via the operation history saving processing unit 18.

Further, the operation history editing means 21 reads the comment data index from the operation history data file 19 to which the comment data index is added by receiving the operation history data output request from the operator, and this is read as a key. The comment data file 41 is searched for comment data and the function of writing the comment data into the operation history output data file 22 is added.

Therefore, in the second embodiment,
Memorize comments set by the operator for each index,
Since it is possible to select the comment index during CRT operation, the comment can be added to the operation history output data using the index as a key to add free human comment information. Therefore, it becomes easy to search the operation history data.

FIG. 6 is a flow chart showing the interactive operation by the operator in the second embodiment of the present invention. When a new comment to be added to the operation history data is to be registered (S1), the operator uses the input means to make a request to call the comment registration screen (S2). That is, using the CRT display device 12, the touch input means 11, the keyboard input means 13 and other input means for the man-machine interface, a request for calling the comment registration screen is made. The request for calling the comment registration screen from the operator is
The comment registration dialogue processing means 4 via the input / output processing means 14
Informed to 0. In the comment registration dialogue processing means 40,
A comment registration screen 43 as shown in FIG. 7 is displayed on the CRT display device 12 via the input / output processing means 14 (S
3).

After that, all the comment registration operations are performed by the dialogue on the comment registration screen 43. First, the operator uses the touch input means 11 to select the area of the index (1 to 5) for which a comment is to be registered (S).
4). The comment to be set from now on will be set in the comment data file 41 as a comment having the index touch-selected here.

Next, the comment contents are keyed in by the keyboard input device 13 or the like (S5). For example, if an operation is to be performed for the purpose of testing the operating end, a comment such as "test" can be added to the history data by keying in and registering it with the keyboard input device 13 or the like. When the history data is searched later, it can be determined that the data is the data when the operation is performed on a trial basis.

After inputting the comment, the "Registration" area on the dialog of the comment registration screen 43 is touched by the touch input means 11
And the like, the comment contents input by the comment registration dialogue processing unit 40 via the input / output processing unit 14 via the keyboard input device 13 and the like through the input / output processing unit 14 and the comment data which is a storage medium together with the index selected by the touch. The file 41 is written and saved. FIG. 8 shows the comment data file 41.

Next, a comment is selected and set before the CRT operation operation is performed. When the operator operates the CRT operation processing means 15, before the operation is performed, a comment to be added to the history data of the CRT operation operation to be performed is set. In that case, for example, first, the operator uses the input means to request calling of the comment selection screen 44 (S6). The request for calling the comment selection screen from the operator is transmitted to the comment selection dialogue processing means 42 via the input / output processing means 14. In the comment selection dialogue processing means 42, the comment selection screen 44 as shown in FIG.
It is displayed on the T display device 12 (S7).

After that, all comment setting operations are performed by dialogue in the comment selection screen 44. First, the operator uses the touch input means 11 to select the area of the index to be added to the history data of the CRT operation operation to be performed. Next, the "selection" area on the dialog of the comment selection screen 44 is touched by the touch input means 1
Touch selection using 1 or the like. As a result, the comment selection dialogue processing means 42 via the input / output processing means 14 sets the index of the comment touch-selected using the touch input means 11 on the comment selection screen 43 via the operation history storage processing means 18 as the operation history. The operation history data file 19 which is a data storage medium is written and saved (S8).

After that, the operator performs a normal CRT operation operation (S9). When the operator performs an operation using the CRT operation processing means 15, the comment index written by the comment selection dialogue processing means 42 in the operation history data is set to the “release” area on the dialogue of the comment selection screen 44. It is added until touch selection is performed using the touch input unit 11.

Next, when it is desired to output the operation history data, the operator uses the CRT display device 12, the touch input means 11, and the keyboard input means 13 for man-machine interface input / output means as in the conventional example. Make an operation history data output request. When the operation history output control means 20 receives an operation history data output request from an operator, the operation history edit means 21 issues an edit request. Upon receiving the edit request, the operation history editing unit 21 reads the comment data index from the operation history data file 19 to which the comment data index is added. Then, using this as a key, the operation history editing means 21 retrieves comment data from the comment data file 41 and writes it in the operation history output data file 22.

As described above, in the second embodiment, the CRT having the operation history storage and output functions of the conventional example is used.
The comment set by the operator is further stored in the operation device for each index, and the index of the comment is selected during the CRT operation operation before the operation. As a result, a comment is added to the operation history output data using the index as a key. That is, since it is possible to add free comment information by the human system, it becomes easy to search the operation history data. Further, it becomes possible to extract the operation that needs to be performed for operating the plant, and it becomes easy to search for the same operation when the same operation as the past operation is required again.

Next, a third embodiment of the present invention will be described. FIG. 10 is a block diagram showing the third embodiment of the present invention. The third embodiment is different from the conventional example shown in FIG. 22 in that it is set by the operator and a collection timing interactive processing means 50 for setting conditions of collection start timing and collection end timing of operation history data. A collection timing data file 51 for storing the collection start timing and the collection end timing conditions and a collection start command for operation history data when a collection start timing condition set by the collection timing interactive processing means 50 are satisfied, When the collection end timing is established, a collection timing execution processing means 52 for issuing a collection end command for operation history data is additionally provided.

Then, the collection timing execution processing means 50
When there is a collection start command from the operation history editing means 2
Reference numeral 1 edits the operation history data as operation history output data and saves it in the operation history output data file 22, and the operation history output processing means 24 displays the operation history output data of the operation end on the CRT display device 12, and the collection timing. When there is a collection end command from the execution processing means 52, the operation history editing means 21 ends the editing of the operation history output data.

That is, the collection timing interactive processing means 5
0 receives a collection timing setting request requested by the operator from the input / output processing means 14, displays a collection timing setting screen for setting conditions of the collection start timing and the collection end timing of the operation history data, and the operator The collection start and collection end timing conditions set by the collection timing data file 51
Write to and save.

Further, the collection timing execution processing means 52
Receives a collection timing control execution request from the collection timing interactive processing means 50, inputs the collection start timing and the collection end timing conditions set from the collection timing data file 51, and the plant control device 25 having these conditions is input. From the plant state signal inputted via the data transmission means 16 from the data transmission means 16 to execute the operation history storage processing means 18 when the collection start condition is satisfied, and stop the operation history storage processing means 18 when the collection end condition is satisfied. .

As a result, the collection start timing and collection end timing conditions set by the operator are compared with the plant status signal input from the plant control device 25, and the history data is collected only for the period when the operator needs the operation history data. By collecting the data, it is possible to prevent the unnecessary data from being erased or overwritten by the unnecessary data.

FIG. 11 shows the collection timing execution processing means 5.
2 is a flowchart showing the processing contents in 2. When it is desired to give a condition to the collection timing of the operation history data, the operator uses the input / output means for the man-machine interface such as the CRT display device 12, the touch input means 11 and the keyboard input means 13 to display the collection timing setting screen. A call request is made (S1). The request for calling the collection timing setting screen from the operator is input / output processing means 1.
4 is transmitted to the collection timing dialogue processing means 50.

The collection timing interactive processing means 50 displays the collection timing setting screen 53 as shown in FIG. 12 on the CRT display device 12 via the input / output processing means 14. After that, all the collection timing setting operations are performed by dialogue on the collection timing setting screen 53. The operator sets conditions for the collection start timing and the collection end timing of the operation history data (S2).

First, the operator uses the keyboard input device 13 to key-in the PID, which is the ID number assigned to the plant status signal to be used as the collection start condition. For example, if a signal such as "press PB for plant activation" is input from the plant control device 25, it is possible to start collection of operation history data at the same time when the plant is activated. And the set PID is ON / OFF
In order to specify in which state the condition is satisfied, whether or not to include NOT is specified by Y / N. For example, if NOT is Y, the set PID
When the state of is OFF, the condition is satisfied, and when NOT is N, the condition is satisfied when the state of the set PID is OFF.

Next, the collection end condition is set in the same manner as the collection start condition. For example, if a signal such as “press plant stop PB” is input from the plant control device 25, the use of this signal allows the operation history data collection to be completed in the same manner as the plant stop. Then, "write" placed on the collection timing setting screen 53
By selecting PB by touching, the collection start and collection end conditions described above are written and stored in the collection timing data file 51 shown in FIG. In the collection timing data file 51 shown in FIG. 13, the presence / absence of NOT processing is Y /
It is represented by 1/0 instead of N.

Further, by touching and selecting "execute" PB arranged on the collection timing setting screen 53, the collection timing interactive processing means 50 makes a collection timing control execution request to the collection timing execution processing means 52. . The collection timing execution processing unit 52 receives the control execution request of the collection timing, refers to the collection start condition and the collection end condition saved in the collection timing data file 51, and collects the collection start condition and the collection end condition from the data transmission unit 16. Enter the current value of the PID specified in (S
3).

Then, it is judged whether or not the current value input from the data transmission means 16 matches the start condition (S).
4). When the current value input from the data transmission unit 16 matches the start condition, the operation history storage processing unit 18 is requested to execute the operation history storage processing (S5). Further, it is determined whether or not the current value input from the data transmission means 16 matches the end condition (S6), and when the current value input from the data transmission means 16 matches the end condition, the operation history storage processing means. A request to stop the operation history saving process is issued to 18 (S7). This allows the operation history data to be saved under the conditions set by the operator.

As described above, in the third embodiment, the CR having the operation history storage and output function in the conventional example is used.
Since the T operation device is provided with a function that allows the start and end conditions of operation history collection to be specified arbitrarily, operation history is collected only during the period when history data is needed, and no history data is required. It is possible not to collect the operation history.

As a result, it is possible to avoid storing unnecessary data in the operation history data file 19 which is the storage destination of the operation history data, and the size of the operation history data file 19 itself can be small. In addition, since the maximum number of stored data in the operation history data file 19 is rarely exceeded, the oldest data will not be erased or overwritten each time. Therefore, there is no danger that the operation history data, which is old in record but very important in operation, will be erased.

Next, a fourth embodiment of the present invention will be described. FIG. 14 is a block diagram showing the fourth embodiment of the present invention. The fourth embodiment differs from the conventional example shown in FIG. 22 in that at the timing when the operation history of the operation by the operator is written in the operation history data file 19, an interrupt for editing the interrupt display data of the operation content is created. Display data editing means 60, interrupt display data storage memory 61 for storing data to be displayed in interrupt, and a plurality of Cs.
Interrupt display means 62 for displaying the operation contents operated by the operator in real time is additionally provided for all the RT display devices 12. Then, in the operation history storage processing unit 18, every time one operation history is written in the operation history data file 19, the address in the operation history data file 19 of the written operation history is transferred to the interrupt display data editing unit 60. It has a processing function to pass.

That is, when the CRT operation processing means 15 executes the operation operation content requested by the operator, the interrupt display means 62 operates the operation history data file 19 by the operation history storage processing means 18.
The contents of the current operation are displayed on the CRT display device 12 as an interrupt screen.

As a result, the CR operated by the operator
T operation operation contents can be displayed in real time by multiple C
By displaying an interruption on the screen of the RT display device 12, it is possible to display it to a remote operator other than the central operation room where the CRT display device 12 is installed, or an operator who is monitoring the operation of the other CRT display device 12 in the central operation room. CRT for operating operators
The operation content of the operation operation can be immediately notified.

Here, the operation history saving processing means 18 writes the operation end number and the operation content input from the CRT operation processing means 15 into the operation history data file 19 as well as the interrupt display data editing means, as in the conventional example. The address in the operation history data file 19 in which the operation history data is written is passed to 60. When the address is input from the operation history saving processing means 18, the interrupt display data editing means 60 reads one operation history data existing at the address in the operation history data file 19.

The read operation history data is written in the interrupt display data storage memory 61 by referring to the operation end information table 23. When the writing to the interrupt display data storage memory 61 is completed, a display request is issued to the interrupt display means 62. Interrupt display data storage memory 61
Has a data structure as shown in FIG. 15, and is edited by the interrupt display data editing means 60 to display the CRT display device 1.
The operation history data for displaying the interruption to 2 is stored.

The interrupt display means 62 receives the display request from the interrupt display data editing means 60, reads the data in the interrupt display data storage memory 61, and through the input processing means 14, all the CRT display devices 12a to 12n.
On the other hand, an interrupt screen as shown in FIG. 16 is displayed. The interrupt screen may be automatically erased after a touch (operation for confirming the operator) in the interrupt screen display area by the operator or a timer is provided and a predetermined time is displayed.

As described above, in the fourth embodiment, the CRT having the operation history storage and output functions of the conventional example is used.
Since the operation device is further provided with an interrupt display data editing means, an interrupt display data storage memory, and an interrupt display means for displaying the operation contents of the CRT operation of the operator on the CRT screen in an interrupt manner, the present CR
T operation operation contents in multiple CRs in real time
The screen of the T display device 12 can be displayed on the screen by interruption such as a list screen and pop-up.

As a result, the operation status of the plant, which was unknown only to the operator who operated the conventional method, can be operated on the screen of the CRT display device 12 at a remote place as well as other operators in the central operation room. Even the operating personnel can recognize the current operation status of the plant and can monitor it as a third party.

Here, in the above-described first to fourth embodiments, the case where the display device 12 is the CRT operation device 1 using the CRT display device has been described, but the CRT display is used as the display device. It can be applied to an operation device using a plasma display device or a liquid crystal display device other than the device. In addition, the first embodiment is the second
It is also possible to apply to the embodiments to the fourth embodiment, and similarly, it is also possible to apply the first embodiment to the fourth embodiment in combination as appropriate.

Further, in the first to fourth embodiments, the embodiments of the present invention are shown respectively with respect to the conventional example shown in FIG. 22 which does not have the free group function. Each embodiment can be applied to the conventional example shown in FIG. 27 having a free group function.

Next explained is the fifth embodiment of the invention. FIG. 17 is a block diagram showing the fifth embodiment of the present invention. This fifth embodiment is shown in FIG.
In contrast to the conventional example having the free group function shown in 7,
When there is a request for allocating an operation end for the operation history from the free group dialogue processing means 26, an operation end satisfying the allocation range specified by the request is extracted by referring to the operation history data file, and the extracted operation end is extracted. A free group automatic edit processing means 70 for making an allocation request is additionally provided to the free group edit processing means 27.

That is, the free group automatic edit processing means 70 receives a request from the free group interactive processing means 26, refers to the operation history data file 19 and automatically extracts an arbitrary operation end, and performs the free group edit processing. Means 2
Request operation end assignment to 7.

As a result, the operation history data can be used as the allocation data of the free group, thereby reducing the load on the operator in the allocation of the free group and effectively utilizing the operation know-how. Since other configurations are the same as those of the conventional example shown in FIG. 27, the same components are designated by the same reference numerals and the description thereof will be omitted.

FIG. 18 is a flow chart showing the flow of processing contents of the free group automatic editing processing means 70.
When the free group dialogue processing means 26 is activated by a command from the operator (S1), a function selection screen is displayed on the CRT display device 12 as shown in FIG. 19 (a). The operator selects the free group allocation function from this function selection screen. When the free group allocation function is selected, the CRT display device 12 next displays the free group allocation screen shown in FIG. Here, when the operator selects the operation end designation allocation on the screen, the conventional free group allocation processing is performed. On the other hand, when the operation history automatic allocation is selected, the allocation range setting screen shown in FIG. 19C is displayed on the CRT display device 12.

On this allocation range setting screen, the operation history time (allocation start time and allocation end time) is set for the range to be automatically allocated in the operation history (S2). Then, after setting the operation history time, by selecting allocation execution on the screen, C
The message "allocation in progress" is displayed in the message display area of the RT display device 12 to inform the operator that the allocation process is in progress (S3).

The free group automatic edit processing means 70
It is determined whether or not there is a request for allocation execution of automatic operation history allocation (S4), and if it is determined that there is a request for allocation execution, the operation history data file 19 is searched (S5).
That is, it is determined whether or not the search covers all of the operation history data file 19 (S6). If not, the operation time of the operation history data file 19 shown in FIG. It is compared with the requested operation history set time (S7). Then, it is determined whether or not there is operation history data within the range (S8), and if within the range, 1 is set to the automatic allocation flag of the operation history data file 19 (S9). When the search of the operation history data file 19 is completed (S6), the operation end number of the operation end whose automatic allocation flag is set to 1 is taken out (S10), and an allocation request is issued to the free group edit processing means 27. (S11).

Next, the free group edit processing means 27
Retrieves the operation end number requested by the free group automatic edit processing means 70 from the operation end information table 23,
The operation end number and the input / output point information are sequentially written into the automatic allocation group provided in the free group operation end allocation data file 28 shown in FIG.

As a result, the operation end in any operation history requested by the operator is automatically allocated to any automatic allocation group of the free group operation end allocation data file 28, and the CRT display device. A message "allocation completed" is displayed in the 12 message display area to notify the operator of the completion of the allocation process.

By performing the above-mentioned processing, the CR by calling the automatically assigned group is the same as calling the free group by the conventional free group function.
T-operation can be operated.

As described above, in the fifth embodiment, the range of automatic allocation required from the operation history is further added to the CRT operation device having the operation history storage / output function and the free group function of the conventional example. By setting by the operator, the operation end number of the specified range is extracted from the operation history data file 19 and automatically assigned to the free group, so that the operator's load in the assignment of the free group can be reduced. Enables effective use of driving know-how.

Here, in the fifth embodiment, a CRT operation device using a CRT display device as a display device has been described, but it goes without saying that an operation device using a display device other than the CRT display device can be used. Yes. Further, it is possible to appropriately combine the fifth embodiment with the first to fourth embodiments having the free group function.

[0104]

As described above, according to the invention of claim 1 or claim 8 of the present invention, the operation history data of the operation operation can be searched by using the operation end number as a key, and therefore any operation can be performed. It is possible to retrieve and output only the historical data relating to the operating end. As a result, the operation history data that has been miscellaneously output by the conventional operation device can be limited to the history data requested by the operator and displayed. Therefore, the load on the operator until the desired history data is reached can be reduced.

According to the invention of claim 2 or claim 3 or claim 8 of the present invention, a comment stored for each index set by the operator can be added to the operation history data. Since the amount of information in the data is abundant and the amount of information that is the key to data retrieval increases, the classification and management of data becomes easy.

According to the invention of claim 4 or claim 5 or claim 8 of the present invention, it is possible to avoid storing unnecessary data in the operation history data file which is the storage destination of the operation history data. The size of the data file itself will be small. Further, since the maximum number of stored operation history data files is rarely exceeded, the oldest data will not be erased or overwritten in each case. For this reason, there is no risk that the operation history data, which is old but very important in operation in order to collect unnecessary operation history data, is erased.

According to claim 6 or claim 7 or claim 8 of the present invention, the contents of the current operation operation by the operator are displayed on the screen of the display device in an interrupted manner.
It becomes possible to display the contents of the current operation operation on the screens of a plurality of display devices in real time by interruption such as a list screen and popup.

As a result, the operating status of the plant, which was unknown only to the operator who operated the conventional method, can be used not only by the other operators in the central operation room but also by the operator operating the remote CRT screen. Also, the current operation status of the plant can be recognized, and it can be monitored as a third party.

According to the ninth aspect of the present invention, the operation history data can be used as the allocation data of the free group. Therefore, in the conventional free group function, the operator can operate from all the operation ends to the operation ends required. It is possible to save all the trouble of searching for and assigning any operating end individually by dialogue, and at the same time, the results of the operation by the operator during plant operation can be assigned to the free group as it is. Therefore, it is possible to reduce the load on the operator in the allocation of the free group and effectively use the operation know-how.
