Further, when it is difficult for the management control unit 260 to generate manufacturing management data on the basis of manufacturing site data, the management control unit 260 may request additional data from the site control device 10.
Specifically, when the management control unit 260 fails to generate manufacturing management data corresponding to manufacturing site data after receiving initial manufacturing site data from the site control device 10, the management control unit 260 may request additional data from the site control device 10 before transmitting the manufacturing management data, receive the additional data, and then generate manufacturing management data using the manufacturing site data and the additional data on the basis of standard data.
In some embodiments, the management control unit 260 may generate the manufacturing management data reflecting only the additional data without reflecting the initial manufacturing site data, or may generate manufacturing management data not reflecting additional data.

That is, when sequential pre-missions for manufacturing site management training cannot be executed, the manufacturing site management training cannot be terminated.
For example, when the pre-mission performance data is not the same as the standard pre-mission performance data, that is, when the pre-mission performance data is not included within a standard range, the management control unit 260 may generate and output a retraining message for re-executing the manufacturing site management training.
In some embodiments, the management control unit 260 may execute manufacturing site management training after on-site integrated management is completed.
For example, the management control unit 260 may perform post-safety training for integrated management of the manufacturing site after on-site integrated management is completed.
In some embodiments, the management control unit 260 may execute manufacturing site management training and then evaluate post-mission performance for the manufacturing site management training.

Next, the management server 20 may classify the manufacturing site data using the keywords extracted based on the standard data (S140).
For example, the management server 20 may use the keywords included in the manufacturing site data to classify the manufacturing site data by each field corresponding to at least one of casting, molding, welding, plastic processing, surface treatment, and heat treatment using the keywords included in the manufacturing site data, classify the manufacturing site data by each apparatus for manufacturing products manufactured by each field, classify the manufacturing site data by each process corresponding to at least one of working time, non-working time, AS time, and working speed for each apparatus, classify the manufacturing site data by each product corresponding to at least one of a casting product, a molding product, a welding product, a plastic processing product, a surface treatment product, and a heat treatment product, classify the manufacturing site data by each biosignal corresponding to at least one of fatigue, movement, and working hours of a worker, and whether the worker commutes to work, or classify the manufacturing site data by each site environment corresponding to at least one of temperature, humidity, smoke, flames, harmful gas, fine dust concentration, oxygen concentration, noise, and vibrations.
Next, the management server 20 may analyze the manufacturing site data classified into the site-specific information, the process-specific information, the product-specific information, the site environment-specific information, and the biosignal-specific information using the keywords extracted based on the standard data, and may generate the manufacturing analysis data corresponding thereto (S150).
Meanwhile, when the received manufacturing site data consists of voice, a video, an image, or conversation data rather than text (S110), the management server 20 may convert the manufacturing site data consisting of voice, a video, an image, or conversation data into text so that the manufacturing site data is recognized (S160).
Next, the management server 20 may generate manufacturing management data using the manufacturing analysis data on the basis of the standard data (S16).
Specifically, as illustrated in
That is, the management server 20 may analyze the management measurement data and estimate an estimated production volume of the product and an estimated lifetime of the apparatus for the remaining lifetime excluding the actual lifetime on the basis of a total lifetime of the apparatus to generate management estimation data using data that matches the standard data.
Next, the management server 20 may analyze the management measurement data to estimate the estimated production volume of the product and the estimated lifetime of the apparatus (S230), and generate management estimation data using data that matches the standard data (S240).
Next, the management server 20 may calculate a maximum production volume of the product and a maximum lifetime of the apparatus at the manufacturing site using the management estimation data on the basis of the standard data (S250), and generate management control data for controlling the manufacturing site in response thereto (S260).
Next, the management server 20 may generate manufacturing management data including the management estimation data and the management control data that correspond to the manufacturing site data on the basis of the standard data (S270).
Next, the site control device 10 may receive a service of on-site integrated management corresponding to the manufacturing site data and then generate a feedback signal for the corresponding service (S18).
In this case, the feedback signal may include information such as satisfaction, accuracy, and reliability for the service.
Next, the management server 20 may generate a feedback control signal for improving the system in response to the feedback signal received from the site control device 10 (S20).
Next, the management server 20 may update the standard data in real time using the manufacturing management data (S22).
In some embodiments, the management server 20 may update the standard data in real time in response to at least one of the feedback signal received from the site control device 10 and the feedback control signal.
Finally, the administrator terminal 30 may monitor the on-site integrated management in real time (S24).
As illustrated in
Next, the management server 20 may extract energy usage and carbon emissions using the simulated manufacturing analysis data and simulate a maximum production volume of a product and a maximum lifetime of an apparatus to generate simulation result data (S340), and generate manufacturing management data including management estimation data reflecting the simulation result data (S350).
As illustrated in
In some embodiments, pre-safety training and/or post-safety training may be executed for the integrated management of the manufacturing site.
For example, the management server 20 may output a method for integrated management of the manufacturing site on a screen.
Next, the management server 20 may execute test questions for the manufacturing site management training visually or audibly (S410), receive results corresponding thereto, and generate mission performance data (S420).
Next, the management server 20 may analyze the mission performance data, and when the mission performance data is the same as standard mission performance data (S430), the management server 20 may generate training result data after the manufacturing site management training is completed (S440).
For example, when the mission performance data is the same as standard mission performance data, the management server 20 may end the manufacturing site management training.
Meanwhile, when the mission performance data is not the same as the standard mission performance data (S430), the management server 20 may generate and output a retraining message for re-executing the manufacturing site management training (S450).
That is, when the mission performance data is not included within a standard range, a worker or an administrator may undergo the manufacturing site management training again.
