The systems and apparatus described herein may be wholly hardware, or may be partially hardware, and partially software. That is, the object virtualization system and the autonomous production operating device according to the embodiments may collectively refer to a hardware device for storing data of a specific format and contents, or for exchanging data by an electronic communication method, and software related thereto. The terms "part", "module", "server", and "system" are used herein to refer to a combination of hardware and software driven by the hardware. For example, the hardware may be a data processing device comprising a CPU or other processor. Also, the software driven by the hardware may refer to a running process, an object, an executable, a thread of execution, a program, and the like.

Further, each part constituting the autonomous production operating device 3 shown in Fig. 2 is not necessarily intended to refer to a separate component which is physically separated. 2, the database 301, the reception unit 302, the virtual object management unit 303, and the task management unit 304 are shown as separate blocks that are distinguished from each other. However, (3) is functionally distinguished by the operation performed thereby. Depending on the embodiment, some or all of the above described units may be integrated in one and the same device, or one or more of the units may be implemented in a separate device physically separate from the other. For example, the components may be components communicatively coupled to each other under a distributed computing environment.

In the database 301, specification information related to the workpiece 100, production information for each process, and operation information of the autonomous mobile means are stored. The production information for each process may include information on parts and tools necessary for each assembly process of the workpiece 100, and fastening information necessary for fastening the parts. The operation information of the autonomous mobile means may include information on the movement path of the autonomous mobile means including one or more work areas and the movement speed of the autonomous mobile means within the movement path. Further, the database 301 may further store job result information received from the work machine 5. [

The receiving unit 302 receives the identification information (e.g., the body number) of the workpiece 100 and the identification information of the smart tag 1 attached to the workpiece 100 at the time of starting assembling the workpiece 100 can do. To this end, the object virtualization system is arranged in a work area and includes a scanner (not shown) for scanning the identification information stamped on the workpiece 100 and / or the identification information of the smart tag 1 and transmitting it to the receiver 302, Time). On the other hand, the identification information of the smart tag 1 may be transmitted from the smart tag 1 to the receiving unit 302 via communication without using a scanner. Also, the receiving unit 302 may periodically receive the position information of the smart tag 1 while the workpiece 100 is being transferred, while the work is being performed. For example, the location information of the smart tag 1 may be transmitted to the receiving unit 302 through the wireless transceiver 2. [ Furthermore, the receiving unit 302 can receive position information of the work equipment 5. [

The virtual object management unit 303 generates a virtual object corresponding to the workpiece 100 and the smart tag 1 attached to the workpiece 100 at the start of assembling the workpiece 100, As the assembly progresses, the information to be written in the smart tag 1 is also stored in the virtual object. For example, the specification information of the workpiece 100 and the work result information according to the completion of each process can be recorded in the virtual object.

In addition, the virtual object management unit 303 updates the position of the virtual object with the lapse of time. In order to update the position of the virtual object, the driving information of the autonomous mobile transportation means stored in the database 301 is used. Since the autonomous mobile transportation means moves the predetermined path at a predetermined speed, it is possible to calculate the time required for the workpiece 100 to pass through each section if the traveling route and the speed for each section are known, The location of the virtual object may be updated periodically to indicate the current location of the virtual object.

Figure 3A is a conceptual diagram illustrating an exemplary deployment of a process area in a smart factory according to one embodiment of the present invention.

With further reference to FIG. 3A, the movement path of the autonomous mobile means may be comprised of one or more work areas 601-604.

Dividing the lengths L11-L14 of the respective work areas 601-604 by the travel speed of the autonomous mobile means in the work areas 601-604 allows the autonomous mobile means to pass through each work area 601-604 The position information of the virtual object is determined and updated so as to indicate the current position of the workpiece 100 calculated using the calculated time.

When the position information is determined, the task management unit 304 transmits the task information to the adjacent work device 5 located within a predetermined distance from the workpiece 100. [ The neighboring work device 5 to which the work information is to be transmitted may be the work device 5 disposed in the work area where the current workpiece 100 is located or the current workpiece 100 Or may be a work machine 5 disposed in a work area positioned next to the work area. The task management unit 304 may transmit the task information to the work equipment 5 via the specification controller 4 disposed in each work area 601-604.

In the present embodiment, the task management unit 304 determines whether or not the position information is received from the smart tag 1 in the state where the position information is periodically received from the smart tag 1, The work information is transmitted by determining the work device 5 and the position information received from the smart tag 1 is stopped or the position information received from the smart tag 1 is different from the position information of the virtual object through the calculation The neighboring 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 can not communicate with the smart tag 1 due to theft or loss of the robot during operation or the sensing of the smart tag 1, Information can be transmitted.

In this case, the driving information stored in the database 301 includes 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 between them In addition, the virtual object management unit 303 may further update the position of the virtual object by using the length information of the blank areas 611-613. The process of calculating the position of the virtual object is the same as that described above with reference to FIG. 3A, except that the time at which the workpiece passes through the margins 611-613 is further considered.

3A and 3B, the movement path of the autonomous moving vehicle is shown as a one-dimensional straight line for convenience of explanation. However, in actual implementation, the movement path of the autonomous moving vehicle may have a more complex form accompanied by a two-dimensional position change.

As shown in FIG. 3C, the movement path of the autonomous moving transportation means may include at least one of the atmospheric region 600 and the plurality of the operation regions 601- In this case, the position information of the virtual object along the movement path may be two-dimensional position information on the plane, such as (x, y) coordinates. However, the movement route described with reference to FIG. 3C is also an example, and the form of the movement route is not limited thereto. For example, the moving path of the autonomous moving vehicle may be a three-dimensional form accompanied by a change in height in the vertical direction. In this case, considering the time when the autonomous moving vehicle moves up and down, For example, (x, y, z) coordinates or the like.

As described above, in the embodiments of the present invention, the virtual object management unit 303 updates the position information of the virtual object so as to reflect the current position of the workpiece 100, and based on the updated position of the virtual object, 304 transmit work information to the adjacent work equipment 5. As a result, even if the smart tag 1 can not communicate with the smart tag 1 due to the loss or theft of the smart tag 1 or the sensing of the smart tag 1, There is an advantage that accurate work information can be delivered to a worker in a timely manner.

In addition, the autonomous production operating device 3 updates the position information of the virtual object based on the driving information of the autonomous moving vehicle during the assembling process (S4). Since the movement path of the autonomous mobile means for carrying the workpiece and the movement speed of each section are predetermined, the position of the virtual object is calculated and updated based on this information, Information.

Next, the autonomous production operating device 3 determines the work equipment 5 located adjacent to the current workpiece 100 based on the position 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 neighboring work device 5 is determined based on the position information received from the smart tag 1, Or when the position information received from the smart tag 1 is different from the position information of the virtual object through the calculation, the neighboring work device 5 can be determined based on the position information of the virtual object.

Next, the work information based on the production information for each process is transmitted to the adjacent work equipment 5 determined in step S5 (S6). The transmitted work information is displayed so that the operator can see the transmitted work information by the display device provided in the work machine 5, thereby allowing the worker to perform the assembly with respect to the workpiece 100 based on the information. The job information transmitted to the adjacent work device 5 may be determined by referring to the job result information stored in the virtual object until the job information is transmitted.

On the other hand, the work machine 5 may further include a step of transferring the work result information to the specification controller 4, thereby transferring the work result to the autonomous production operating device 3 or writing the result to the smart tag 1. [
