Generally, parts such as an automobile body frame and a vehicle exterior panel are manufactured through press working. Particularly, automobile-related parts have too many press dies, and the operator can not individually identify various types of press dies.

Thus, when the mold is to be replaced between the press mold operations, it is impossible to confirm whether the mold to be replaced is correct unless the operator recognizes the information related to the mold to be replaced. Accordingly, .

In addition, since an integrated production monitoring system is not constructed for the operator to grasp the production quantity of each press die product, it is troublesome to check one by one, and the operator can check the pressing state of a specific product There are many cases where reference value information is not provided and depend only on know-how of the worker, so it is somewhat difficult to objectively determine the product defect.

In addition, since it is impossible to grasp a product defect or a non-operating state of a line in real time, a product is unnecessarily advanced to a final press line, resulting in a large number of defective products, and production efficiency is lowered.

Therefore, there is a growing demand for a real-time press-molding product production monitoring system which can improve productivity and quality through inspection of products in real time in the space of such conventional presses or by monitoring production quantities of products.
