In FIG. 3, "processing completed", "operation", "stop", or "general error", which are "data names and signal names", are bit data, and "bit" is set as the "data format". be done. Further, as the "address" in FIG. 3, for example, an address in the PLC of the processing equipment 2 when acquiring various data (text data or bit data) corresponding to "data name, signal name" is set.

The display control information generation unit 33 acquires the learned model TM stored in the model storage unit 31 . Also, the display control information generation unit 33 acquires the new required specification information NY acquired by the required specification information acquisition unit 32 . Thereby, the display control information generation unit 33 generates new display control information NH based on the learned model TM and the new required specification information NY.

Specifically, the display control information generation unit 33 of this example, according to the new required specification information NY shown in FIG. 1” and “Equipment Name 2”, the “Planned Production Quantity” and the “Actual Production Quantity” are generated by bar graphs extending horizontally. In the display mode 14a, the color and size of the bar graph to be displayed are set by new display control information NH based on the color and size displayed by past display control information KH, for example.

Further, according to the new required specification information NY shown in FIG. And new display control information NH is generated that represents the "planned availability" and "actual availability" of "facility name 2" by vertically extending bar graphs. In the display mode 14a, the color and size of the bar graph to be displayed are set by new display control information NH based on the color and size displayed by past display control information KH, for example.

Further, the display control information generation unit 33 of this example, in accordance with the new required specification information NY shown in FIG. New display control information NH is generated that represents the ratio between the number of non-defective products and the number of defective products by a vertically extending bar graph. In the display mode 14a, the color and size of the bar graph to be displayed are set by new display control information NH based on the color and size displayed by past display control information KH, for example.

Further, the display control information generation unit 33 of this example, in accordance with the new required specification information NY shown in FIG. is represented by a vertically extending bar flag, and new display control information NH is generated to represent the "stop rate" by a line graph. In the display mode 14a, the colors and sizes of the bar graphs and line graphs to be displayed are set by new display control information NH based on the colors and sizes displayed by past display control information KH, for example. In addition, the display control information generation unit 33 is not limited to generating one new display control information NH for one "small item", and can also generate a plurality of new display control information NH. be.

The output unit 34 outputs the new display control information NH generated by the display control information generation unit 33 to the database 15 of the management device 10, as shown in FIG. In this example, the output unit 34 outputs new display control information NH to the database 15 . However, the output unit 34 can also directly output the new display control information NH generated by the display control information generation unit 33 to the control unit 12 of the management device 10 . The control unit 12 of the management device 10 controls the operation of the display unit 14 according to the new display control information NH stored in the database 15, and the display modes shown in FIGS. 14a displays "actual production", "operating rate", "first-run rate", and "equipment abnormality history". Note that the control unit 12 of the management device 10 can output signals based on, for example, the "operating rate", the "first-run rate", and the "equipment abnormality history" to the PLC of the processing equipment 2. FIG. Thereby, the PLC of the processing equipment 2 can turn on the signal lamp 5 depending on the situation.

Further, the control unit 12 stores the new display control information NH displayed on the display unit 14 in the database 15 in association with the new required specification information NY. Thereby, the learning processing equipment 20 performs machine learning using the new display control information NH generated by the display control information generation unit 33 as the past display control information KH, and updates the learned model TM. Then, when new requirement specification information NY is created on a different occasion than this time, the output device 30 uses the updated trained model TM to generate a new request specification information NY corresponding to the new requirement specification information NY. Generate display control information NH.

As can be understood from the above description, according to the display system 1, the output device 30 is generated by the learning processing equipment 20 only by creating new required specification information NY reflecting the needs of the administrator and the worker. New display control information NH can be generated using the learned model TM. Then, by generating new display control information NH, the control unit 12 of the management device 10 reflects the display mode of the display unit 14 according to the new display control information NH, that is, the needs of the administrator and the operator. Various information can be displayed and provided depending on the display mode. Therefore, it is possible to reduce the man-hours required for the administrator and the operator to create new display control information NH, and to easily display various information on the display unit 14 in the display mode 14a that reflects the needs of the administrator and the operator. can be made

(5. Separate example)
In this example described above, the output destination of various data D, for example, the address of the PLC, is set in advance in the new required specification information NY. Then, the display control information generation unit 33 acquires desired signals and values from the corresponding signal lamps 5 and detection devices 6 according to the addresses set in the new required specification information NY, and generates new display control information NH. I made it

By the way, the database 15 accumulates and stores past required specification information KY in which output destinations of various data D are set and past display control information KH corresponding to the past required specification information KY. For this reason, the model generating unit 23 of the learning processing equipment 20 performs machine learning using, for example, the address of the past required specification information KY as an explanatory variable and the past display control information KH as an objective variable, thereby outputting various data D. A trained model can be generated that represents the correlation between the previous and display 14a. As a result, for example, even if the "address" is not set in the new requirement specification information NY, various data corresponding to the items displayed on the "output screen" can be generated using the generated learned model. The output destination of D can be set automatically. Therefore, in this case, the manager or worker can omit the setting of the output destination of the various data D and create new required specification information NY. Various kinds of information can be displayed on the display unit 14 by means of 14a.
