The event generation unit 200 may include a condition generation unit 210, a disturbance information generation unit 220, and a data conversion unit 230.

The condition generator 210 generates a condition for generating an abnormal condition of the 3D virtual facility generated by the PLC controller 300, which will be described later.

More specifically, the disturbance range setting unit 221 forcibly sets the disturbance information to a minimum value when the disturbance information is smaller than the predetermined minimum value, and forcibly sets the disturbance information to the maximum value when the disturbance information is larger than the maximum value.

 The disturbance information can be classified into a facility influence factor, a product influence factor, and a facility-equipment influence factor.

Here, the facility influence factor may be a factor for arbitrarily changing the roll gap, the stroke, etc. when the rolling facility is a rolling stand. The product influencing factor may be a factor for arbitrarily changing the material information (e.g., width, thickness, top height, width direction position, etc.) rolled and discharged in a particular rolling stand. The facility-equipment impact factor may be a factor that affects the after rolling facility as a result of the operation of the previous rolling facility.

The data conversion unit 230 converts the conditional condition and the disturbance information into a script file and provides processed event information.

Next, the PLC control unit 300 generates and provides an operation signal of the rolling facility based on the event information.

The simulation processing unit 400 has a function of generating a 3D virtual equipment corresponding to the rolling facility and then simulating the shape and position of a virtual product produced from the 3D virtual equipment and the 3D virtual equipment based on the operation signal .

The simulation processing unit 400 designs a 3D virtual facility corresponding to the rolling process facility and reflects a kinematic function (e.g., linear motion, rotational motion, multi-axis motion, etc.) in the designed 3D virtual facility, ) Simulates the rolling operation of the 3D virtual machine in accordance with the operation signal provided in the 3D virtual machine.

More specifically, the simulation processing unit 400 may include a 3D shape extracting unit 410, a virtual driving unit 420, an operation calculating unit 430, and an operation calculation managing unit 440.

The virtual driving unit 420 performs a function of applying a kinematic operation model so that the 3D virtual facility is operated based on the operation signal provided by the PLC control unit 300. [ Here, different operation models may be applied to the 3D virtual facility depending on the operation shape.

The operation calculation unit 430 calculates a shape and a position of a virtual product produced according to the operation and operation of the 3D virtual facility based on the operation model applied to the 3D virtual facility.

The operation calculation management unit 440 determines whether the virtual product can be input to the subsequent 3D rolling process facility, and then determines whether the rolling process is proceeding according to the determination result.

Finally, the display unit 500 displays a result value of the simulation processing unit to the user.

Meanwhile, the disturbance information generating step S220 may include a disturbance range setting step S221 for setting the maximum and minimum values of the disturbance information, and the minimum value and the minimum value may be a state in which the 3D virtual equipment is capable of rolling It indicates the range that can be maintained.

More specifically, the disturbance range setting step S221 includes setting the disturbance information to a minimum value when the disturbance information is smaller than the predetermined minimum value, and setting the disturbance information to a maximum value when the disturbance information is greater than the maximum value. Here, the disturbance information can be divided into a facility influence factor, a product influence factor, and an influence factor between facilities-equipment, and detailed description of each factor will be omitted in the above-mentioned relation.
