Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is suitable for transmission of large-capacity files such as image data and transmission speed, and is suitable for production lines where the production order is determined, such as a production line for modular housing. Regarding an instruction display system.

0002

[Prior Art] Conventionally, in production lines for such modular housing, work instructions for each process at the work site were given in advance by distributing copied design drawings for each product to each worker. Ta.

[0003] However, in recent years, terminal devices have been installed near each worker in such housing production lines, and work instruction files for one process sent from a host computer are now being installed near each worker. By displaying the information on the screen of the terminal device, the user can work while looking at the design drawings, markings, etc. displayed on the screen.

[0004] In other words, when each worker completes the work of one process, he or she operates the operation button of the terminal device to update the screen with the design drawings, etc. of the next process.

[0005] When such an operation button is pressed, the terminal device outputs a request to send a file for the next process to the host computer, and imports the file for the next process sent from the host computer in response to this request. The design drawing of the imported file is displayed on the screen.

[0006] In this way, in the conventional system, work instruction files for all workpieces and all processes are stored in the host computer as image data, and necessary files are transmitted in response to a transmission request from each terminal device. It looks like this.

[0007]

[Problem to be Solved by the Invention] However, since it takes time to transmit large files such as image data, it is difficult for a field worker who has completed the work of the currently displayed process to press the operation button on the terminal device. Even if an attempt is made to update the display screen to the screen for the next process, a situation occurs in which the workpiece for the next process comes down the line before it is actually updated. In particular, when a plurality of terminal devices are installed, there is a problem in that if transmission requests are sent from each terminal device at the same time, the response on the host computer side is further delayed.

[0008] The present invention was made in view of the above circumstances, and its purpose is to keep the display screen update time within a certain amount of time that allows field workers to wait, and to simultaneously send transmission requests from each terminal device. It is an object of the present invention to provide a work instruction display system capable of preventing a decrease in response due to such factors.

[0009]

[Means for Solving the Problems] In order to solve the above problems, the work instruction display system of the present invention creates a work instruction file according to production planning data, and classifies the created file by type of workpiece. At the same time, each workpiece is sorted in the order of process, and the factory host computer, which stores the files sorted in this way for each workpiece, communicates with each terminal device installed at the work site in the factory. The mutual communication system includes a transmission request operation unit that sends various transmission requests to the factory host computer in each terminal device, and a transmission request operation unit that sends a file transmission request to the factory host computer. A storage unit that stores file groups for multiple processes before and after the process, including files for the process currently being worked on, sent from the computer according to the production order; A display unit that reads and displays a file, and an update operation unit that updates the display screen of this display unit from a file of one process stored in the storage unit to a file of another process. It is.

0010

[Operation] A request to send a file is made to the factory host computer by operating the transmission request operation section of each terminal device installed near each worker at the work site.

Upon receiving this transmission request, the factory host computer reads out a group of files for a plurality of processes before and after the process, including the file for the process currently in progress, according to the production order, and sends them to the terminal device that made the transmission request.

[0012] In the terminal device, this file group is stored in the storage section.

[0013] Here, the storage unit is configured to be able to store, for example, five files, centering on the file (F1) of the process currently being worked on, and three files on the previous process side (next process side). (F2, F3, F4) and one file (F0) on the previous process side (completed process side) are stored.

[0014] In principle, the file (F1) of the process currently being worked on is first displayed on the display section of the terminal device.

[0015] Furthermore, by appropriately operating the update operation section of the terminal device, the operator updates the screen on the display section, for example, to a file (F2) for one step ahead (next step). At this time,
All five files stored in the first storage section are updated one by one. In other words, the three files on the previous process side are (
F3, F4, F5) and the file F5 is newly read, one file on the previous process side is updated to (F1) and the original file F0 is deleted.

[0016] As a result, the on-site worker can select one file from the file (F1) of the process currently being worked on, which is displayed on the display section.
If you want to see the file (F2) of the next process (next process) or the file (F0) of the previous process (completed process), you can save it to the storage unit by operating the update operation unit appropriately. It is possible to immediately read out and display on the screen from a group of files that are currently available, and it is possible to view the file you want instantly (actually, after as much time as the worker can wait, for example, 0.5 seconds). .

[0017]

Furthermore, the terminal control section 22 and the storage section 23 are bidirectionally connected.

As shown in FIG. 3, the storage unit 23 stores the files containing the files of the process currently in progress, which are transmitted from the factory host computer A in accordance with the production order by operating the “Required” button 21a of the operation unit 21. It is designed to store files for five processes.

Specifically, centering on the file (F1) of the process currently being worked on, three files (F2, F3, F4) on the previous process side (next process side) and the previous process side (completed process side)
One file (F0) is stored.

That is, the storage unit 23 is constituted by a VRAM or the like, and has five storage areas corresponding to each file so that the above five files can be stored. In this embodiment, the file (F0) of the previous process (completed process) is stored in the first storage area R1, and the file (F1) of the process currently being worked on is stored in the second storage area R2. , the file one process ahead (F

Furthermore, the output of the display section 24 is led to a printer 25, and the configuration is such that the file (design drawing with markings, etc.) displayed on the display section 24 can be printed.

Next, the operation of the work instruction display system having the above configuration will be explained.

Prior to the operation of this system, a necessary file group is first stored in the file storage section 14 of the factory host computer A.

That is, the operator of the factory host computer A inputs production plan data. This production plan data is led to the file editing section 13 via the main control section 12. Further, the file editing unit 13 is led to a file group for each workpiece, which has been subjected to reading and processing of design drawings by an editing machine (not shown).

The file editing section 13 rearranges the file group for each work according to the given production plan data, and stores the rearranged file group data in the file storage section 14.

With the above operations, the process of storing necessary data in the file storage section 14 is completed.

[0040] After this, the workers who operate the terminal devices B1, B2, etc. installed at each work site,

Processing after this start-up operation will be explained for one terminal device B1.

The on-site worker using the terminal device B1 first turns on the "required" button 21a of the operating section 21 when starting up the device.

As a result, a file transmission request is sent from the terminal device B1 to the factory host computer A. Upon receiving this transmission request, the factory host computer A searches the file storage unit 14 and retrieves the file of the process currently being worked on according to the production order (in this case, the process to be performed first after startup). The files of the preceding and succeeding five processes are read out and sent to the terminal device B1 that made the transmission request. The terminal device B1 stores these five files in a predetermined storage area of the storage unit 23. That is, as described above, the file (F0) of the previous process (in this case, the last process performed on the previous day) is stored in the first storage area R1, and the file (F0) for the process currently being worked on is stored in the second storage area R2. A process file (F1) is stored, a file (F2) for one process ahead is stored in the third storage area R3, a file (F3) for two processes ahead is stored in the fourth storage area R4, and a file (F3) for the next process is stored in the fourth storage area R4. A file (F4) three steps ahead is stored in the storage area R5.

At this time, the display unit 24 also displays the file F of the process currently being worked on, which is stored in the second storage area R2.

At this time, the contents stored in the storage unit 23 are not updated, unlike in the case of operation (1) described above.

From this state, when the "Next" button 21c is turned on one more time (that is, turned on four times from the initial state), the terminal control section 22 stores data in the fifth storage area R5 of the storage section 23. The file 3 steps ahead (F4
) is then read out from the file storage section 14 of the factory host computer A, the file (F5) for four processes ahead, and stored in the empty fifth storage area R5 of the storage section 23 (Fig. 8).

[0061] Thereafter, the terminal control unit 22 reads out the file (F5) for four steps ahead stored in the fifth storage area R5 of the storage unit 23, outputs it to the display unit 24, and
The screen display is updated from the file three steps ahead (F4) to the file four steps ahead (F5) shown in FIG.

Thereafter, the above operation is repeated each time the "Next" button 21c is turned ON, and the display screen of the display section 24 is sequentially updated with the file for the next process.
Only the storage contents of the fifth storage area R5 of the storage unit 23 are sequentially updated to the files for the next process.

(3) Operation when the "previous" button 21d is turned on.

[0064] When the "previous" button 21d is turned on once, the terminal control section 22 transfers data from the storage section 23 to the first storage area R.
The file (F
0) is output to the display unit 24, and the screen display shows the file (F1) of the process currently being worked on as shown in FIG.
is updated to the file (F0) one step before, shown in FIG.

[0065] At this time, the storage contents of the storage unit 23 are not updated, as in the case of operation (2) described above.

From this state, when the "previous" button 21d is turned on once more (that is, turned on twice from the initial state), the terminal control section 22 stores data in the first storage area R1 of the storage section 23. The file from the previous process (F0
), and then reads the file (F-1) from two processes ago from the file storage section 14 of the factory host computer A, and stores it in the first storage area R1 of the storage section 23, which is now in an empty state. let Thereafter, the terminal control unit 22 reads the file (F-1) stored in the first storage area R1 of the storage unit 23 and displays it on the display unit 24.
Output to the file (F0) of the previous process and display the screen display.
The file is updated to the file (F-1) two steps earlier shown in FIG. 11.

From then on, the above operation is repeated each time the "previous" button 21d is turned ON, and the display screen of the display section 24 is sequentially updated to the file from the previous step.
Accordingly, only the storage contents of the first storage area R1 of the storage unit 23 are sequentially updated to the file one step before.

(4) Operation when the "current" button 21e is turned on.

For example, as shown in FIG. 12, a file (F8) seven steps ahead is stored in the fifth storage area R5 of the storage section 23, and the file seven steps ahead is displayed on the screen of the display section 24. (F8) is displayed.

In this state, the "current" button 21e
When you turn ON once, the terminal control unit 22
The file (F1) of the process currently being worked on is stored in the second storage area R2 of File of the process currently in progress shown in 13 (F1)
Update to. In addition, the terminal control unit 22 erases the file (F8) for 7 processes ahead stored in the fifth storage area R5 of the storage unit 23, and then deletes the file 3 processes ahead from the file storage unit 14 of the factory host computer A. The file (F4) is read out and stored in the empty fifth storage area R5 of the storage section 23.

Further, as shown in FIG. 14, for example, the file (F-
4) is stored, and this 4 is displayed on the screen of the display unit 24.
It is assumed that the file before the process (F-4) is displayed.

In this state, the "current" button 21e
When you turn ON once, the terminal control unit 22
The file (F1) of the process currently being worked on is stored in the second storage area R2 of
, the file of the process currently being worked on (F1
). In addition, the terminal control unit 22 erases the file (F-4) from four processes ago that was stored in the first storage area R1 of the storage unit 23, and then deletes the file (F-4) from the file storage unit 14 of the factory host computer A. File before process (F0
) and stores it in the first memory section 23 which is now empty.
is stored in the storage area R1.

[0073] In this way, by turning on each operation button of the operation section 21 as necessary, the site worker can:
It is possible to instantly view not only the file of the process currently being worked on, but also the files of the next process or the previous process, or the files of the two or three processes ahead.

In the above embodiment, the screen drawing speed (ie, screen display speed) in the VRAM constituting the storage section 23 is substantially within 0.5 seconds. Furthermore, since the storage unit 23 is configured to store files for a plurality of processes, it is possible to sufficiently handle file rendering at the current network transmission speed. Furthermore, even if the number of terminals increases to, say, 10, the response will essentially be 2.
Within seconds.

In the above embodiment, five files can be stored in the storage section 23, but the number of files that can be stored is not limited to five.

[0076]

[Effects of the Invention] The work instruction display system of the present invention can select any one of the groups of files of a plurality of processes before and after, including the file of the process currently being worked on, stored in the storage unit, by appropriately operating the update operation unit. Since the configuration is configured to read the file for one process and display it on the display screen, regardless of the transmission speed from the factory host computer to the terminal,
This has the effect of allowing you to instantly view drawings of several processes before and after the process you are currently working on.
