That is, the virtualization system of things and the autonomous production operation apparatus according to the embodiments may collectively refer to a hardware device and software related thereto for storing or transmitting data of a specific format and content in an electronic communication method. The terms "part", "module", "server" and "system" are intended to refer to the combination of hardware and software driven by the hardware. For example, the hardware may be a data processing device including a CPU or other processor. In addition, software driven by hardware may refer to a running process, an object, an executable, a thread of execution, a program, or the like.

In addition, each part constituting the autonomous production operation apparatus 3 shown in FIG. 2 is not intended to refer to separate components that are necessarily physically separated. That is, in FIG. 2, the database 301, the receiver 302, the virtual object manager 303, and the job manager 304 are illustrated as separate blocks that are separated from each other, but this is an autonomous production operating apparatus according to an embodiment of the present invention. (3) is functionally divided by the operation performed thereby. In some embodiments, some or all of the above-described units may be integrated in the same single device, or one or more of the units may be implemented as separate devices that are physically separated from other units. For example, each unit may be components that are communicatively coupled to each other under a distributed computing environment.

The database 301 stores specification information related to the work object 100, production information for each process, and operation information of the autonomous mobile transportation means. Production information for each process may include information about parts or tools required for each assembly process of the work object 100 and fastening information required for fastening parts. The driving information of the autonomous mobile transportation means may include information on a moving path of the autonomous mobile transportation means including at least one work area and a moving speed of each section of the autonomous mobile transportation means in the moving path. In addition, the database 301 may further store work result information received from the work device 5.

The receiving unit 302 receives identification information (eg, a vehicle body number) of the work object 100 and identification information of the smart tag 1 attached to the work object 100 when the assembly of the work object 100 is started. can do. To this end, the object virtualization system is disposed in the work area and a scanner (not shown) for a worker to scan identification information and / or identification information of the smart tag 1 and the like imprinted on the work object 100 and transmit the scanned information to the receiving unit 302. May further include). On the other hand, the identification information of the smart tag 1 may be transmitted from the smart tag 1 to the receiver 302 through communication without using a scanner. In addition, the receiver 302 may periodically receive the position information of the smart tag 1 while the work object 100 is being transferred and the work is performed. For example, the location information of the smart tag 1 may be transmitted to the receiver 302 through the wireless transceiver 2. Furthermore, the receiver 302 may receive the position information of the work device 5.

The virtual object manager 303 generates a virtual object corresponding to the work object 100 and the smart tag 1 attached thereto at the time when assembly of the work object 100 is started, and the work object 100 is applied to the work object 100. As the assembly proceeds, the information to be recorded in the smart tag 1 is equally stored in the virtual object. For example, specification information of the work object 100 and work result information according to completion of each process may be recorded in the virtual object.

In addition, the virtual object manager 303 updates the position of the virtual object over time. In order to update the position of the virtual object, the driving information of the autonomous transportation means stored in the database 301 is used. Since the autonomous mobile transportation means moves a predetermined path at a predetermined speed, if the movement path and the speed of each section are known, the time required for the work object 100 to pass through each section can be calculated, and the work target ( The position of the virtual object may be periodically updated to indicate the current position of 100).

3A is a conceptual diagram illustrating an exemplary arrangement of process areas in a smart factory according to one embodiment of the invention.

Referring further to FIG. 3A, the movement path of the autonomous transportation means may consist of one or more work areas 601-604. In each work area 601-604, the operator is located and the specification controller 4, the work machine 5, and the like are located, and the worker is controlled by the autonomous transport means. And -604, the assembly of the parts is performed based on the job information displayed on the work device 5.

At this time, the virtual object manager 303 uses the length L11-L14 of each work area 601-604 to be defined in advance and the moving speed of the autonomous transport means in each work area 601-604. Update the position of the object. The length L11-L14 of each work area 601-604 is divided by the moving speed of the autonomous transport means in the work area 601-604, and the autonomous transport means passes through each work area 601-604. Since the time required to calculate can be calculated, the location information of the virtual object is determined and updated to indicate the current position of the work object 100 calculated using the calculated time.

When the position information is determined, the job manager 304 transmits the job information to the adjacent work device 5 located within a predetermined distance from the work object 100. The adjacent work device 5 to which the work information is to be transmitted may be the work device 5 arranged in the work area in which the current work object 100 is located, or the current work object 100 is located on the moving path. It may also be a work machine 5 arranged in a work area located after the work area. The job management unit 304 may transmit job information to the work device 5 via the specification controller 4 disposed in each work area 601-604.

In one embodiment of the present invention, the job management unit 304, based on the location information received from the smart tag 1 in a state where the location information is periodically received from the smart tag 1 to the receiving unit 302 Determine the work device 5 and transmit the work information, but the reception of the location information from the smart tag 1 is stopped or the location information received from the smart tag 1 is different from the location information of the virtual object through calculation. If so, the adjacent work device 5 is determined based on the location information of the virtual object, and the work information is transmitted. Therefore, even when the smart tag 1 cannot be communicated with the smart tag 1 due to theft or loss during operation, or the sensing of the smart tag 1 is impossible, the work is performed in accordance with the assembly progress of the work object 100. Information can be transferred.

3B is a conceptual diagram illustrating another exemplary arrangement of process areas in a smart factory according to an embodiment of the present invention.

As shown in FIG. 3B, the movement path of the autonomous transport means may further include a margin area 611-613 between each work area 601-604 in addition to the plurality of work areas 601-604 described above. have. In this case, the driving information stored in the database 301 is not only the length information L11-L14 of each work area 601-604 but also the length information L21-L23 of the blank area 611-613 therebetween. The virtual object manager 303 may further update the position of the virtual object by time using the length information of the blank areas 611-613. The process of calculating the position of the virtual object is the same as described above with reference to FIG. 3A, except that the time for which the work object passes through the margins 611-613 is further considered.

3A and 3B, the movement path of the autonomous mobile transportation means is shown in a linear one-dimensional form for convenience of description. However, in actual implementation, the movement path of the autonomous transport means may have a more complicated form involving a two-dimensional position change.

3C is a conceptual diagram illustrating another exemplary arrangement of process areas in a smart factory according to an embodiment of the present invention.

As shown in FIG. 3C, the movement path of the autonomous transportation means may include one or more inflection sections including the standby area 600 and the plurality of work areas 601-608 and the movement direction thereof changed. In this case, the positional information of the virtual object along the moving path may be two-dimensional positional information on a plane such as (x, y) coordinates. However, the movement route described with reference to FIG. 3C is also exemplary, and the form of the movement route is not limited thereto. For example, the movement path of the autonomous transportation means may be a three-dimensional form with a change in height in the vertical direction, in which case the position information of the virtual object is taken into account in consideration of the time until the autonomous transportation means moves in the vertical direction. For example, it may calculate in the form of (x, y, z) coordinates.

As described above, in the embodiments of the present invention, the virtual object manager 303 updates the position information of the virtual object to reflect the current position of the work object 100, and based on the updated position of the virtual object, the task manager ( 304 transmits the job information to the adjacent work device 5. As a result, even when the smart tag 1 cannot be communicated with the smart tag 1 due to loss or theft of the smart tag 1, or the like, the smart tag 1 cannot be sensed, based on the information stored in the virtual object and its location information. It has the advantage of delivering accurate job information to the operator in a timely manner.

1 and 4, at the time when assembly using the workpiece 100 is started, the autonomous production operation apparatus 3 performs an operation of the workpiece 100 scanned by a worker using a scanner (not shown). The identification information and the identification information of the smart tag 1 are received (S1). The autonomous production operating apparatus 3 generates a virtual object corresponding to the combination of the received work object 100 and the smart tag 1 (S2).

While the assembling process is performed while the work object 100 is transported by the autonomous mobile transportation means, the autonomous production operating apparatus 3 receives the position information of the work devices 5 arranged in each work area (S3). . In addition, the autonomous production operation apparatus 3 may receive location information from the smart tag 1 attached to the work object 100.

In addition, the autonomous production operation apparatus 3 updates the positional information of the virtual object based on the driving information of the autonomous mobile transportation means during the assembly process (S4). Since the moving path and the moving speed of each section of the autonomous vehicle for transporting the work object are predetermined, the current position of the work object 100 is determined by updating the position of the virtual object based on this information. To be reflected as information.

Next, the autonomous production operating apparatus 3 determines the work device 5 positioned adjacent to the current work object 100 based on the location information of the smart tag 1 or the virtual object (S5). For example, in a state where position information is periodically received from the smart tag 1, the adjacent work device 5 is determined based on the position information received from the smart tag 1, but the position information from the smart tag 1 is determined. If the reception of the is stopped or the location information received from the smart tag 1 is different from the location information of the virtual object through calculation, the adjacent work device 5 may be determined based on the location information of the virtual object.

Next, the work information based on the production information for each process is transmitted to the adjacent work device 5 determined in the above-described step S5 (S6). The transmitted work information is displayed to be visible to the worker by the display element provided in the work device 5, so that the worker can perform the assembly of the work object 100 based on this. The job information transmitted to the adjacent work device 5 may be determined by further referring to the job result information stored in the virtual object until the job information is transmitted.

Meanwhile, the work device 5 may further include transmitting the work result information to the specification controller 4 so as to transmit the work result to the autonomous production operation apparatus 3 or to record it in the smart tag 1.
