Description

Auxiliary system for rolling operation
Technical Field
The present invention relates to a system for assisting a rolling operation performed in a rolling line.
Background
A rolling line for rolling materials such as steel is provided with a computer room and an operation room. The computer room is provided at a place remote from the rolling line. The remote operator resides in a computer room. The remote operator is a process manager or a quality manager that performs setting calculation of rolling control performed in the rolling line. On the other hand, the operation room is provided in the vicinity of the rolling line. The field operator resides in the studio. The field operator performs various operations for intervention in rolling control while directly or indirectly monitoring the state of work in the rolling line.
A monitor for displaying the status of the work in the rolling line is installed in the computer room. The remote operator may perform various operations for intervention in rolling control while monitoring the work state via the monitor. That is, the remote operator may perform the same intervention operation as that performed by the field operator during execution of the rolling control. In such a case, it is common practice for the remote operator to converse with the field operator directly by telephone during the execution of the rolling control.
After the rolling control of this time is completed, the remote operator may make various adjustments in preparation for the next rolling control based on the history of the operation data of the site operator. In this case, it is common practice for a remote operator to access a shared database in which operation data is recorded to acquire the operation data. The shared database is also accessed by field operators. The reason is to confirm the operation data by the remote operator during the period from the end of the previous rolling control to the start of the current rolling control. Another reason is to confirm the contents of the operation performed by the site operator himself during the previous rolling control.
Japanese patent No. 4795498 discloses a work assisting apparatus. The work support device adjusts the timing of guiding the content to be operated by the site operator during the execution of the rolling control, according to the skill level of the site operator. However, the guidance does not consider the operation content of the remote operator. Therefore, the same problem as that in the conventional rolling control occurs. That is, during execution of the rolling control, it takes time and effort for one operator to grasp the contents of the operation of the other operator. If one operator does not sufficiently grasp the content of the operation of the other operator, it may cause a work failure.

The remote operator additionally monitors the status of the work via the monitors 41a to 41 d. The remote operator also performs an operation for intervening in rolling control using the terminal 43 or an input device (not shown) connected to the terminal 43 according to the state of the work. Hereinafter, the intervention operation of the rolling control by the remote operator is referred to as "second operation". Data relating to the second operation (hereinafter, referred to as "second operation data") is written in the memory 45. The processor 44 performs processing for displaying the second operation data on any of the monitors 42a to 42 c. The computer room 40 is connected to the control device 20 and the auxiliary device 50. The processor 44 performs processing for transmitting the second operation data to these devices.

Details of the transfer process will be described later. The "operation data" is a general name of the first operation data and the second operation data.
1-2. flow of Primary data
Fig. 2 is a diagram showing the flow of main data in the rolling work support system 100. The command data D1 is sent from the control device 20 to the rolling line 10. The instruction data D1 includes numerical value data. The command data D1 also includes data of the control parameters and the gain that have been changed in accordance with the operation data.

The first operation data of the case where the transmission destination is the auxiliary device 50 is referred to as first operation data D41. The second operation data of the case where the transmission destination is the control device 20 is referred to as second operation data D32. The second operation data of the case where the transmission destination is the auxiliary device 50 is referred to as second operation data D42.
1-3 characteristics of embodiment 1
1-3-1. problems of the past
Fig. 3 is a diagram illustrating an example of intervention in rolling control. In the example shown in fig. 3, the materials 11a and 11b are rolled in sequence in the finish rolling machine shown in fig. 1. During the period from the time T1 to the time T2, the material 11a is rolled. During the period from the time T3 to the time T4, the material 11b is rolled. Time T1 is preceded by the time that the material 11a waits to be rolled. The period from time T2 to time T3 is the time during which the material 11b waits to be rolled.
As shown in fig. 3, before time T1, the first operation data D31a and D31b are transmitted from the cab 30 to the control device 20 in this order. In addition, 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 D31 b. In addition, during the period from the time T1 to the time T2, the first operation data D31c is transmitted from the cab 30 to the control device 20. In addition, during the period from the time T2 to the time T3, the first operation data D31D is transmitted from the cab 30 to the control device 20.
Conventionally, in preparation for rolling or during rolling, a remote operator and a site operator are in contact with each other, so that one operator can grasp details of an intervention operation of the other operator. However, not only is such a connection troublesome, but there is a risk of a malfunction of the work due to an audible error. In addition, in the conventional system, the remote operator and the field operator may perform the same intervention operation on the same material. Thus, the intervention operation is excessively performed, and it is difficult to maintain the quality of the product.
1-3-2. improvement point of embodiment 1
In view of this, in embodiment 1, transfer processing is performed. Fig. 4 is a diagram illustrating the transfer process. As explained in fig. 2, the operation data is transmitted not only to the control device 20 but also to the auxiliary device 50. Therefore, the same data as the data transmitted to the control device 20 is written in the memory 52 in preparation for or during the progress of rolling. The first operation data D41 a-D41D shown in FIG. 4 are the same as the first operation data D31 a-D31D illustrated in FIG. 3, respectively. The second operation data D42a is the same as the second operation data D32a illustrated in fig. 3. In fig. 4, "steel grade classification: AA "," thickness division "and" width division "correspond to product data. The "operation destination", "operation item", and "operation amount" correspond to operation data.
In the transfer process, transfer data D6 is read from the memory 52. The transfer data D6 includes the latest data written to the memory 52 and the product data associated therewith. In the transfer process, the transfer data D6 is transmitted from the terminal at the operation site to a terminal installed in a different operation room from the operation room in which the terminal is installed (hereinafter, also referred to as "terminal of another operation room"). For example, consider the case where the latest data is the first operation data D41 a. In this case, the terminal 43 corresponds to a terminal of another 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 D42 a. In this case, the terminal 33 corresponds to a terminal of another 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 destination of the data. Specifically, the transfer data D6 in the case where the terminal of the other operation room is the terminal 33 is referred to as first notification data D71. The transfer data D6 when the terminal of the other operation room is the terminal 43 is referred to as second notification data D72.
In the case where the terminal 33 receives the first notification data D71, the first notification data D71 is written to the memory 35. The processor 34 performs a process for displaying the first notification data D71 on any one of the monitors 32a to 32 c.
In the case where the terminal 43 receives the second notification data D72, the second notification data D72 is written to the memory 45. The processor 44 performs processing for displaying the second notification data D72 on any one of the monitors 42a to 42 c.
1-4. Effect
According to embodiment 1, transfer processing is performed. According to the transfer process, the latest data of the operation data is transmitted to the terminal of the other operation room together with the product data associated therewith. Therefore, in preparation for rolling or during the progress of rolling, the site operator and the remote operator can grasp details of the intervention operation of the other operator without being in contact with each other. Therefore, the operation can be stabilized and the product quality can be kept constant.
In the transfer process, even when only the latest data of the operation data is transmitted to the terminal of another operation room, the above-described effect can be expected. This is because the product data is displayed on the monitors 32a to 32c and 42a to 42c in preparation for rolling or during the progress of rolling. Therefore, it is expected that the field operator and the remote operator can associate the latest data of the operation data with the product data displayed on the monitors by themselves.
After the end of the current rolling control, the remote operator may make various adjustments based on the history of the first operation data D41 for the next rolling control. According to the transfer processing, the history of the first operation data D41 is written to the memory 45 as the second notification data D72. Therefore, even when the remote operator performs the adjustment, the remote operator can omit the trouble of accessing the memory 22 to check the operation history of the field operator. The data changed by the adjustment is written into the memory 35 as the first notification data D71. Therefore, the field operator can omit the trouble of accessing the memory 22 to check the adjustment history of the remote operator, and the field operator can easily grasp the result of the adjustment by the remote operator before the next rolling control.
In addition, according to embodiment 1, the first notification data D71 is displayed on any of the monitors 32a to 32c, and the second notification data D72 is displayed on any of the monitors 42a to 42 c. Therefore, one operator can visually grasp details of the intervention operation of the other operator.
1-5. correspondence between embodiment 1 and the invention
In embodiment 1, the operation chamber 30 corresponds to the "first operation chamber" of the first invention. The computer room 40 corresponds to the "second operating 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.

2-1 characteristics 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 sequence in the finish rolling mill. The times T1 to T4 are the same as those described in fig. 3. During the period from the time T5 to the time T6, the material 11c is rolled. The period from time T4 to time T5 is the time during which the material 11c waits to be rolled.
As shown in fig. 5, before time T1, the first operation data D31a and D31b are transmitted from the cab 30 to the control device 20 in this order. In addition, before the time T1, the second operation data D32a is transmitted from the computer room 40 to the control device 20. In addition, during the period from the time T2 to the time T3, the first operation data D31c is transmitted from the cab 30 to the control device 20. In addition, during the period from the time T4 to the time T5, the first operation data D31D and D31e are sequentially transmitted from the cab 30 to the control device 20.

In fig. 6, "steel grades are classified: AA "," thickness division "and" width division "correspond to product data. "time", "operation place", "operation item", and "operation amount" correspond to operation data.
In the second transfer process, the transfer data D6 is read out from the memory 52. The transfer data D6 includes the latest data written to the memory 52 and the product data associated therewith. The processing is the same as the transfer processing (hereinafter referred to as "first transfer processing") of embodiment 1. In the second transfer process, the same operation data as the "product data", "operation place", and "operation item" of the latest data is read as the common data D8. The common data D8 can be selected only from data traced back for a certain period of time (for example, one hour) from the latest data. .
For example, in the case where the newest data is the first operation data D41e, the common data D8 may select the first operation data D41b and 41D. The "product data" of the first operation data D41c is different from the first operation data D41 e. The "operation ground" of the second operation data D42a is different from the first operation data D41 e. The time of backtracking of the first operation data D41a from the latest data does not exceed a certain time. Therefore, these operation data are not selected as the common data D8.
In the second transfer process, the feature data is generated based on the latest data and the common data D8. The characteristic data includes the maximum value rMAX, the minimum value rMIN, and the average value rAVE of the "operation amount" of the latest data and the common data D8. For example, when the latest data is the first operation data D41e, the feature data is generated based on the operation amounts α 3, α 5, and α 6.
In the second transfer process, the latest data, the product data, and the feature data are transmitted as transfer data D6 to the terminal of the other operation room. The processing of the processor 34 when the terminal 33 receives the first notification data D71 is the same as that described in embodiment 1. The processing when the terminal 43 receives the second notification data D72 is also the same as that described in embodiment 1.
2-2. Effect
According to embodiment 2, the second transfer process is performed. According to the second transfer process, the characteristic data is transferred in addition to the data transmitted by the first transfer process. By transferring the characteristic data, the tendency of the "operation amount" of the material common to the material currently being rolled with respect to the "product data" and the "operation item" by the operator on the one hand can be easily grasped by the operator on the other hand. Therefore, the operation can be stabilized and the product quality can be kept constant.
3. Embodiment 3
Next, embodiment 3 of the present invention will be described with reference to fig. 7. Hereinafter, descriptions overlapping with those of embodiment 1 or 2 will be omitted as appropriate.
3-1 characteristics of embodiment 3
Fig. 7 is a diagram for explaining a transfer process (hereinafter referred to as a "third transfer process") according to embodiment 3. In the third transfer process, the timing to perform the third transfer process 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 operator wishes to accept the first notification data D71. As the desired timing, timing of each time, timing of the next time, or both of the two of the second operation can be exemplified. The next timing is a timing at which a material having the same hierarchical data as that of a material rolled in the past is supplied to the rolling line 10. The layered data consists of "steel type division", "thickness division", and "width division".
The default value of the first timing data D91 is set to "timing at each time". If the site operator changes the desired timing, the changed first timing data D91 is transmitted from the cab 30 to the auxiliary device 50. The desired timing is changed via the terminal 33.
The second timing data D92 is data indicating the timing at which the remote operator wishes to accept the second notification data D72. As the desired timing, timing of each time, timing of the next time, or both of the first operation and the second operation can be exemplified. The definition of the timing of the next time is the same as the definition of the timing of the next time included in the first timing data D91.
The default value of the second timing data D92 is set to "timing at each time". If the remote operator changes the desired timing, the changed second timing data D92 is transmitted from the computer room 40 to the auxiliary device 50. The desired timing is changed via the terminal 43.
In embodiment 3, the schedule data D10 is transmitted from the control device 20 to the assist device 50. As shown in fig. 7, the schedule data D10 includes rolling order data and hierarchical data.
In the third transfer process, when the desired timing includes "timing of the next time", the transmission timings of the first notification data D71 and the second notification data D72 are determined based on the schedule data D10, the first timing data D91, and the second timing data D92. For example, attention is paid to the second rolled steel type BB. The transmission timing in this case is the timing at which the third steel type BB is supplied to the rolling line 10. The fifth rolled steel type CC was noted. The sending timing in this case is the timing at which the sixth steel type CC is supplied to the rolling line 10.
When the "next timing" is not included in the desired timing, that is, when the "timing at 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 embodiment 3, the third transfer process is performed. According to the third transfer process, the timing at which the auxiliary 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 an operator who always wants to grasp the operation movement of an operator staying in another room, "timing at each time" or "timing at both of the time and the next time" is suitable. On the other hand, operators with high skill may feel troublesome about "timing each time". In this regard, according to the third transfer process, the first notification data D71 or the second notification data D72 can be received according to the preference of the operator, and therefore, the operation efficiency of the operator can be improved. Therefore, the operation can be stabilized and the product quality can be kept constant.
