Description

Rolling operation support system

The present invention relates to a system that supports a rolling operation performed on a rolling line.

A computer room and an operation room will be provided on the rolling line where materials such as steel are rolled. The computer room is provided at a location away from the rolling line. A remote worker is stationed in the computer room. The remote worker is a process manager or quality manager who performs the setting calculation of the rolling control performed on the rolling line. On the other hand, the cab is provided near the rolling line. On-site workers are stationed in the driver's cab. Field workers perform various operations to intervene in rolling control while directly or indirectly monitoring the status of operations on the rolling line.

The computer room will be equipped with a monitor that displays the operating status of the rolling line. The remote worker may perform various operations to intervene in the rolling control while monitoring the operation status through this monitor. That is, the remote worker may perform an intervention operation similar to the intervention operation performed by the field worker during the rolling control. In such a case, it is customary for the remote worker and the field worker to directly communicate with each other by telephone during the rolling control.

The remote worker may also make various adjustments in preparation for the next rolling control based on the history of operation data by the field worker after the end of the rolling control this time. In this case, the remote worker usually obtains the data by accessing the shared database in which the operation data is recorded. Field workers also access the shared database. The reason for this is to confirm the operation data performed by the remote operator between the end of the previous rolling control and the start of the current rolling control. Another reason is to confirm the contents of the operations performed by the field workers themselves in the previous rolling control.

Japanese Patent No. 4795498 discloses an operation support device. This operation support device adjusts the time for guiding the contents to be operated by the field worker during the rolling control according to the skill level of the field worker. However, this guidance does not consider the operation contents of the remote operator. Therefore, a problem similar to the problem in the conventional rolling control occurs. That is, it takes time and effort for one worker to grasp the contents of the operation of the other worker during the rolling control. If one worker does not fully understand the contents of the operation of the other worker, it may cause an operation trouble.

1-3. Features of Embodiment 1 1-3-1. Conventional Problems FIG. 3 is a diagram illustrating an example of intervention for rolling control. In the example shown in FIG. 3, the materials 11a and 11b are rolled in this order in the finish rolling mill shown in FIG. From time T1 to time T2, the material 11a is rolled. From time T3 to time T4, the material 11b is rolled. Before the time T1, it is the time when the rolling of the material 11a is awaited. The period from the time T2 to the time T3 is the time during which the rolling of the material 11b is awaited.

As shown in FIG. 3, before the time T1, the first operation data D31a and D31b are transmitted from the driver's cab 30 to the control device 20 in this order. Further, before the time T1, the second operation data D32a is transmitted from the computer room 40 to the control device 20. The transmission of the second operation data D32a is performed between the transmission of the first operation data D31a and the transmission of the first operation data D31b. Further, between the time T1 and the time T2, the first operation data D31c is transmitted from the driver's cab 30 to the control device 20. Further, between the time T2 and the time T3, the first operation data D31d is transmitted from the driver's cab 30 to the control device 20.

Conventionally, during preparation for rolling or during rolling, a remote worker and a field worker communicate with each other, and one worker grasps the details of the intervention operation of the other worker. However, it is troublesome to make such a contact, and there is a risk that misunderstanding may lead to operational troubles. Further, in the conventional method, a remote worker and a field worker may perform a similar intervention operation on the same material. Then, the intervention operation is excessively performed, and it becomes difficult to keep the quality of the product constant.

1-3-2. Improvement points of the first embodiment Therefore, in the first embodiment, the transfer process is performed. FIG. 4 is a diagram illustrating a transfer process. As described with reference to FIG. 2, the operation data is transmitted not only to the control device 20 but also to the support device 50. Therefore, during the preparation for rolling or during rolling, the same data as the data transmitted to the control device 20 is written in the memory 52. The first operation data D41a to D41d shown in FIG. 4 are the same as the first operation data D31a to D31d described with reference to FIG. The second operation data D42a is the same as the second operation data D32a described with reference to FIG. In FIG. 4, "steel type classification: AA", "thickness classification", and "width classification" correspond to product data. The "operation source", "operation item", and "operation amount" correspond to operation data.

In the transfer process, the transfer data D6 is read from the memory 52. The transfer data D6 includes the latest data written in the memory 52 and the product data associated therewith. In the transfer process, the transfer data D6 is transferred from the operation source terminal to a terminal installed in an operation room different from the operation room in which the terminal is installed (hereinafter, also referred to as a "terminal in another operation room"). Will be sent to. For example, consider the case where the latest data is the first operation data D41a. In this case, the terminal 43 corresponds to the terminal in the separate operation room. The transfer data D6 includes the first operation data D41a and the product data associated therewith. Consider the case where the latest data is the second operation data D42a. In this case, the terminal 33 corresponds to the terminal in the separate operation room. The transfer data D6 includes the second operation data D42a and the product data associated therewith.

The transfer data D6 is distinguished by the data transmission destination. Specifically, the transfer data D6 when the terminal in the separate operation room is the terminal 33 is referred to as the first notification data D71. The transfer data D6 when the terminal in the separate operation room is the terminal 43 is referred to as the second notification data D72.

When the terminal 33 receives the first notification data D71, the first notification data D71 is written in the memory 35. The processor 34 performs a process for displaying the first notification data D71 on any one of the monitors 32a to 32c.

When the terminal 43 receives the second notification data D72, the second notification data D72 is written in the memory 45. The processor 44 performs a process for displaying the second notification data D72 on any one of the monitors 42a to 42c.

1-4. Effect According to the first embodiment, the transfer process is performed. According to the transfer process, the latest operation data is transmitted to a terminal in another operation room together with the product data associated with the operation data. Therefore, during preparation for rolling or during rolling, one worker can grasp the details of the intervention operation of the other worker without the field worker and the remote worker communicating with each other. It becomes. Therefore, it is possible to stabilize the operation and keep the quality of the product constant.

In the transfer process, the above effect is expected even when only the latest operation data is transmitted to the terminal in another operation room. This is because the product data is displayed on the monitors 32a-32c and 42a-42c during the preparation for rolling or during the rolling. Therefore, the field worker and the remote worker are expected to associate the latest operation data with the product data displayed on these monitors by themselves.

After the end of the rolling control this time, the remote worker may make various adjustments in preparation for the next rolling control based on the history of the first operation data D41. According to the transfer process, the history of the first operation data D41 is written in the memory 45 as the second notification data D72. Therefore, when the remote worker makes adjustments, it is possible to save the trouble of the remote worker accessing the memory 22 and investigating the operation history of the field worker. Further, the data changed by the adjustment is written in the memory 35 as the first notification data D71. Therefore, it is not necessary for the field worker to access the memory 22 to investigate the adjustment history of the remote worker, and the field worker can easily grasp the adjustment result of the remote worker before the next rolling control. Is possible.

In addition, according to the first embodiment, the first notification data D71 is displayed on any one of the monitors 32a to 32c, and the second notification data D72 is displayed on any one of the monitors 42a to 42c. Therefore, one worker can visually grasp the details of the intervention operation of the other worker.

1-5. Correspondence between the first embodiment and the invention In the first embodiment, the driver's cab 30 corresponds to the "first operation room" of the first invention. The computer room 40 corresponds to the "second operation room" of the first invention. The terminal 33 corresponds to the "first terminal" of the first invention. The terminal 43 corresponds to the "second terminal" of the first invention. At least one of the monitors 32a to 32c corresponds to the "first monitor" of the second invention. At least one of the monitors 42a to 42c corresponds to the "second monitor" of the second invention.

2. Embodiment 2
Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. Hereinafter, the description overlapping with the first embodiment will be omitted as appropriate.

2-1. Features of Embodiment 2 FIG. 5 is a diagram illustrating another example of intervention in rolling control. In the example shown in FIG. 5, the materials 11a, 11b and 11c are rolled in this order in the finish rolling mill. Times T1 to T4 are as described in FIG. From time T5 to time T6, the material 11c is rolled. The time between the time T4 and the time T5 is the time during which the rolling of the material 11c is awaited.

As shown in FIG. 5, before the time T1, the first operation data D31a and D31b are transmitted from the driver's cab 30 to the control device 20 in this order. Further, before the time T1, the second operation data D32a is transmitted from the computer room 40 to the control device 20. Further, between the time T2 and the time T3, the first operation data D31c is transmitted from the driver's cab 30 to the control device 20. Further, between the time T4 and the time T5, the first operation data D31d and D31e are transmitted from the driver's cab 30 to the control device 20 in this order.

FIG. 6 is a diagram illustrating a transfer process (hereinafter, referred to as “second transfer process”) performed in the second embodiment. The first operation data D41a to 41e shown in FIG. 6 are the same as the first operation data D31a to 31e described with reference to FIG. The second operation data D42a is the same as the second operation data D32a described with reference to FIG. In FIG. 6, "steel type classification: AA", "thickness classification" and "width classification" correspond to product data. The "time", "operation source", "operation item", and "operation amount" correspond to operation data.

In the second transfer process, the transfer data D6 is read from the memory 52. The transfer data D6 includes the latest data written in the memory 52 and the product data associated therewith. Up to this point, it is the same as the transfer process of the first embodiment (hereinafter, referred to as "first transfer process"). In the second transfer process, the latest data and the operation data in which the "product data", the "operation source" and the "operation item" are common are read out as the common data D8. As the common data D8, data that goes back by a certain time (for example, 1 hour) from the latest data is selected.

For example, when the latest data is the first operation data D41e, the first operation data D41b and 41d are selected as the common data D8. The first operation data D41c is different from the first operation data D41e in the "product data". The second operation data D42a is different from the first operation data D41e in the “operation source”. The time of the first operation data D41a traced back from the latest data exceeds a certain time. Therefore, these operation data are not selected as the common data D8.

In the second transfer process, characteristic data is generated based on the latest data and common data D8. The characteristic data includes the maximum value rMAX, the minimum value rMIN, and the average value rAVE of the "manipulation amount" of the latest data and the common data D8. For example, when the latest data is the first operation data D41e, characteristic data is generated based on the operation amounts α3, α5 and α6.

In the second transfer process, the latest data, product data, and characteristic data are transmitted as transfer data D6 to a terminal in another operation room. The processing of the processor 34 when the terminal 33 receives the first notification data D71 is as described in the first embodiment. The process when the terminal 43 receives the second notification data D72 is also as described in the first embodiment.

2-2. Effect According to the second embodiment, the second transfer process is performed. According to the second transfer process, not only the data transmitted in the first transfer process but also the characteristic data is transferred. By transferring the characteristic data, one worker can easily check the tendency of one worker's "operation amount" with respect to the material currently being rolled and the material having the same "product data" and "operation item". It becomes possible to grasp. Therefore, it is possible to stabilize the operation and keep the quality of the product constant.

3. 3. Embodiment 3
Next, a third embodiment of the present invention will be described with reference to FIG. 7. Hereinafter, the description overlapping with the first or second embodiment will be omitted as appropriate.

3-1. Features of the third embodiment FIG. 7 is a diagram illustrating a transfer process of the third embodiment (hereinafter, referred to as a “third transfer process”). In the third transfer process, the timing at which the third transfer process is performed is determined based on the first timing data D91 and the second timing data D92.

The first timing data D91 is data indicating the timing at which the field worker wishes to receive the first notification data D71. Examples of the desired timing include the timing of each second operation, the next timing, or both of these timings. The next timing means the timing at which a material having the same layering data as the layered data of the material rolled in the past is provided to the rolling line 10. The stratified data is composed of "steel type classification", "thickness classification" and "width classification".

The default of the first timing data D91 is set to "timing each time". When the field worker changes the desired timing, the changed first timing data D91 is transmitted from the driver's cab 30 to the support device 50. The change of the desired timing is performed via the terminal 33.

The second timing data D92 is data indicating the timing at which the remote worker desires to receive the second notification data D72. Examples of the desired timing include the timing of each first operation, the next timing, or both of these timings. The definition of the next timing is the same as that of the next timing included in the first timing data D91.

The default of the second timing data D92 is set to "timing each time". When the remote worker changes the desired timing, the changed second timing data D92 is transmitted from the computer room 40 to the support device 50. The change of the desired timing is performed via the terminal 43.

In the third embodiment, the schedule data D10 is transmitted from the control device 20 to the support device 50. As shown in FIG. 7, the schedule data D10 includes rolling order data and stratified data.

In the third transfer process, when the "next timing" is included in the desired timing, the first notification data D71 and the second notification data D72 are based on the schedule data D10, the first timing data D91, and the second timing data D92. The transmission timing is determined. For example, pay attention to the steel type BB to be rolled second. The transmission timing in this case is the timing at which the third steel grade BB is provided to the rolling line 10. Focus on the fifth rolled steel grade CC. The transmission timing in this case is the timing at which the sixth steel grade CC is provided to the rolling line 10.

When the "next timing" is not included in the desired timing, that is, when the "timing each time" is selected, the content of the third transfer process is the same as the content of the first transfer process.

3-2. Effect According to the third embodiment, the third transfer process is performed. According to the third transfer process, the timing at which the support device 50 transmits the first notification data D71 and the second notification data D72 is determined based on the first timing data D91 and the second timing data D92. For workers who want to keep track of the operation trends of workers stationed in separate rooms, "timing each time" or "timing both each time and next time" is convenient. On the other hand, if the worker has a high degree of skill, "timing each time" may be troublesome. In this regard, according to the third transfer process, it is possible to receive the first notification data D71 or the second notification data D72 according to the preference of the worker, so that the work efficiency by the worker can be improved. .. Therefore, it is possible to stabilize the operation and keep the quality of the product constant.
