The processor 310 may acquire EBC data and virtual factory data from the data acquisition unit 100 according to a command stored in the memory 320 . In other words, the processor 310 may acquire new EBC data and store it in the EBC storage, and when new EBC data is acquired, the information obtained by acquiring the new EBC data is stored in the configuration DB 210 , the product DB 220 and It can be reflected in the production process DB (230).

Here, as the simulation method, a conventional simulation method may be used.

When a simulation result satisfies a preset criterion according to a command stored in the memory 320 , the processor 310 may generate an EBC set based on the plurality of EBCs.

A method of simulating a virtual factory based on EBC according to an embodiment of the present invention will be described using an automobile door trim assembly process as an example.

First, the automatic door trim assembly process may be performed using infrared detection sensor equipment, vision-based barcode recognition equipment, screwdriver equipment, AGV (automated guided vehicle) equipment, and PPC (panel pc) equipment.

Here, the infrared detection sensor equipment may mean equipment that detects when an AGV enters the workbench in the idle state and sends an 'AGV in' signal to the vision-based barcode recognition equipment, and the vision-based barcode recognition equipment detects infrared rays in the idle state When the AGV receives the 'AGV in' signal from the sensor equipment, it acquires a barcode image through auto zoom in/auto focus/auto shooting, extracts the barcode from the acquired image, and makes the barcode more vivid during the barcode extraction process. It may mean equipment that performs pre-processing so that it can be easily recognized, and transmits the result of recognizing a barcode from the pre-processed barcode image to the barcode processing program of PPC.

In addition, the screwdriver equipment may refer to equipment that transmits the assembled number of screws to the PPC when the operator assembles the number of screws set by the PPC in the fixed position of the door trim in the idle state, and the AGV equipment is idle. When the start signal is received from the server, it enters the assembly process workbench, and when entering the assembly process workbench, it recognizes the tag on the bottom of the workbench and stops until the assembly process is completed. When the screw assembly work is completed, it starts from the server It may refer to equipment exiting the current workbench to enter the next process workbench after receiving a signal. The PPC equipment may refer to equipment that has an Ethernet communication interface with a server and performs a function of receiving information required for an assembly process from a server or notifying the server of an assembly process state.

In addition, a simulation may be performed by generating a virtual unit process in which each of the above-described equipment is used, and generating an equipment processing model through mapping of the virtual equipment and the virtual unit process according to the equipment instance model.

In other words, using the equipment processing model of the infrared detection sensor equipment, when the AGV enters the workbench, it is possible to perform a simulation that sends an 'AGV in' signal, and 'AGV in' using the equipment processing model of the vision-based barcode recognition equipment By receiving the signal, it is possible to perform simulations of acquiring barcode images, extracting barcodes, pre-processing, and sending recognition results to PPC. In addition, using the equipment processing model of the screwdriver equipment, if the operator assembles at a fixed location, it is possible to perform a simulation of transferring the number of screws to the PPC. A simulation of leaving the workbench can be performed by receiving the stop and start signals. A simulation may be performed to receive information using the equipment processing model of the PPC equipment and inform the server of the status.

In addition, in the virtual device registration method according to an embodiment of the present invention, when the simulation result satisfies the user's criteria, the automatic door trim assembly process, which is the equipment used for the simulation, is an infrared sensor device, a vision-based barcode recognition device, and a screw EBCs of driver equipment, AGV equipment, and PPC equipment can be created as one EBC set, and the created EBC set can be registered in the EBC storage.

Therefore, if the user performs the simulation again, the EBC set of the car door trim assembly, rather than individually extracting the EBCs of the infrared detection sensor equipment, vision-based barcode recognition equipment, screwdriver equipment, AGV equipment, and PPC equipment from the EBC storage can be extracted, and simulation can be performed using the EBC set.

In other words, using the equipment processing model of each equipment in the car door trim assembly equipment set, simulation to send 'AGV in' signal when AGV enters the workbench, receive 'AGV in' signal to acquire barcode image, barcode extraction, pre-processing And a simulation that transmits the recognition result to the PPC, a simulation that transmits the number of screws to the PPC when an operator assembles at a fixed location, a simulation of entering a workbench, and a simulation of leaving the workbench by receiving stop and start signals until the assembly process is completed. In addition, a simulation that notifies the status to the server can be performed together.

Thereafter, by creating equipment instance models 1 to 7 based on EBCs 1 to 7 and mapping each to seven unit processes, seven equipment processing models can be generated, and simulations can be performed based on the seven equipment processing models. there is.

When the simulation result using the equipment processing model corresponding to the unit processes 1 to 4 is higher than the standard set by the user, EBCs 1 to 4 can be generated as one EBC set, and the EBC set corresponding to the sub-process 1234 is generated. The obtained information may be transmitted and reflected to the configuration DB 210 , the product DB 220 , and the production process DB 230 .
