Description

Leather Manufacturing Process and Logistics Management System with RFID

Technical Field

The present invention relates to an application technology to which a wireless processing system (RFID) technology and a LON (Local Operating Network) technology using power line communication are applied to a leather processing process and logistics management system.

The prior art to which the invention belongs

Most of the leather processing is done by using machines, but because the specifications of the raw materials are not constant and the uses and colors of the products are varied, they work with the hands of skilled workers.

In addition, since the automation of the machine to be used is quite expensive, the automation of most of the machine is a lot of difficulties. Large leather companies use expensive automated machines, but a large number of small companies have no choice but to use old machines. Therefore, it is very difficult to completely achieve the automation and unmanned promotion of the facilities of the leather processing industry.

Unlike the processing of other products, the leather processing process is handled by the worker by hand, so it is difficult to identify the location and inventory of the leather in the process. Therefore, the bar code system has been applied as a method for identifying the location of leather and the number of stocks in the process, but it is not directly applied due to various processing processes (chemical treatment, cleaning, cutting, vibration, drying, dyeing, etc.). I couldn't. That is, barcode retention in the chemical treatment / dyeing / cleaning process and barcode damage in the drying and vibration process. In addition, a method of writing a color code on the leather and counting it for each process has been applied, but has not achieved great effectiveness.

<Technology applied in the present invention>

The radio recognition system is used under the name RFID (Radio Frequency Identification) and is expected to play a role as a medium suitable for the coming ubiquitous era. The radio recognition system consists of a transponder and a reader. First, transponders are divided into active and non-powered passives, which can be read and written to the transponder and only read. In addition, it is divided into 100kHz ~ 500kHz, 10MHz ~ 15MHz, 860MHz ~ 930MHz, 2.4GHz ~ 5GHz according to frequency band, and the recognition distance, speed and price are determined for each.

This wireless recognition system is applied to pharmaceutical, health care, amusement park, event business, manufacturing industry, library, video rental store, logistics management, non-cash payment, retail business, security, shipping, warehousing, transportation management, hospitality, etc. have.

LON stands for Local Operating Network and is similar to the concept of a local area network (LAN) for data networks. The concept is to communicate with devices such as the lowest sensors and actuators, and devices that are responsible for communication and monitoring / control functions. The data network is a single protocol, for example, Ethernet / TCPIP. This concept is focused on the fact that the computer industry has evolved from the days of mainframe / terminals to workstations, now intelligent PCs, and client / server architectures. It is derived from the philosophy of going from Peer-to-peer to Flat Architecture.

<Problems with Prior Art>

The method of attaching a barcode to the leather can cause problems with the preservation of the barcode over the whole process (particularly washing, dyeing and fatal damage of the barcode in the process),

Printing a serial number on the leather may cause a preservation problem on the printed surface like a bar code.

The method of attaching RFID to the leather sheet is not suitable for using the recognition medium on each leather because of the preservation of the recognition medium in the chemical treatment process due to external physical pressure and impact applied to the leather.

In order to solve the problems of the prior art to which the present invention belongs, by applying LON technology applied with RFID and power line communication to the existing obsolete leather processing process management system, more efficient process management and process technology improvement and information (ubiquitous) society The aim is to expand the application of the technology.
